Summary The two biggest challenges in solving practical optimization problems are computational intractability, and the presence
of uncertainty: most problems are either NP-hard, or have incomplete input data which
makes an exact computation impossible.
Recently, there has been a huge progress in our understanding of intractability, based on spectacular algorithmic and lower bound techniques. For several problems, especially those with only local constraints, we can design optimum
approximation algorithms that are provably the best possible.
However, typical optimization problems usually involve complex global constraints and are much less understood. The situation is even worse for coping with uncertainty. Most of the algorithms are based on ad-hoc techniques and there is no deeper understanding of what makes various problems easy or hard.
This proposal describes several new directions, together with concrete intermediate goals, that will break important new ground in the theory of approximation and online algorithms. The particular directions we consider are (i) extend the primal dual method to systematically design online algorithms, (ii) build a structural theory of online problems based on work functions, (iii) develop new tools to use the power of strong convex relaxations and (iv) design new algorithmic approaches based on non-constructive proof techniques.
The proposed research is at the
cutting edge of algorithm design, and builds upon the recent success of the PI in resolving several longstanding questions in these areas. Any progress is likely to be a significant contribution to theoretical
computer science and combinatorial optimization.

Project The evolution of adaptive response mechanisms
Researcher (PI) Franz WEISSING
Host Institution (HI) RIJKSUNIVERSITEIT GRONINGEN
Call Details Advanced Grant (AdG), LS8, ERC-2017-ADG
Summary In an era of rapid climate change there is a pressing need to understand whether and how organisms are able to adapt to novel environments. Such understanding is hampered by a major divide in the life sciences. Disciplines like systems biology or neurobiology make rapid progress in unravelling the mechanisms underlying the responses of organisms to their environment, but this knowledge is insufficiently integrated in eco-evolutionary theory. Current eco-evolutionary models focus on the response patterns themselves, largely neglecting the structures and mechanisms producing these patterns. Here I propose a new, mechanism-oriented framework that views the architecture of adaptation, rather than the resulting responses, as the primary target of natural selection. I am convinced that this change in perspective will yield fundamentally new insights, necessitating the re-evaluation of many seemingly well-established eco-evolutionary principles.
My aim is to develop a comprehensive theory of the eco-evolutionary causes and consequences of the architecture underlying adaptive responses. In three parallel lines of investigation, I will study how architecture is shaped by selection, how evolved response strategies reflect the underlying architecture, and how these responses affect the eco-evolutionary dynamics and the capacity to adapt to novel conditions. All three lines have the potential of making ground-breaking contributions to eco-evolutionary theory, including: the specification of evolutionary tipping points; resolving the puzzle that real organisms evolve much faster than predicted by current theory; a new and general explanation for the evolutionary emergence of individual variation; and a framework for studying the evolution of learning and other general-purpose mechanisms. By making use of concepts from information theory and artificial intelligence, the project will also introduce various methodological innovations.

Project Aiding Social Protection: the political economy of externally financing social policy in developing countries
Researcher (PI) Andrew Martin Fischer
Host Institution (HI) ERASMUS UNIVERSITEIT ROTTERDAM
Call Details Starting Grant (StG), SH2, ERC-2014-STG
Summary This research proposal explores the political economy of international development assistance (aid) directed towards social expenditures, examined through the lens of a particular financial quandary that has been ignored in the literature despite having important economic and political repercussions. The quandary is that aid cannot be directly spent on expenditures denominated in domestic currency. Instead, aid needs to be first converted into domestic currency whereas the foreign exchange provided is used for other purposes, resulting in a process prone to complex politics regarding domestic monetary policy and spending commitments.
The implications require a serious rethink of many of the accepted premises in the political economy of aid and related literatures.
It is urgent to engage in this rethinking given tensions between two dynamics in the current global political economy: a tightening financial cycle facing developing countries versus an increasing emphasis in international development agendas of directing aid towards social expenditures. The financial quandary might exacerbate these tensions, restricting recipient government policy space despite donor commitments of respecting national ownership.
The proposed research examines these implications through the emerging social protection agenda among donors, which serves as an ideal policy case given that social protection expenditures are almost entirely based on domestic currency. This will be researched through a mixed-method comparative case study of six developing countries, combining quantitative analysis of balance of payments and financing constraints with qualitative process tracing based on elite interviews and documentary research. The objective is to re-orient our thinking on these issues for a deeper appreciation of the systemic political and economic challenges facing global redistribution towards poorer countries, particularly with respect to the forthcoming Sustainable Development Goals.

Project "Rights, Responsibilities, and the HIV/AIDS Pandemic: Global Impact on Moral and Political Subjectivity"
Researcher (PI) Jarrett Zigon
Host Institution (HI) UNIVERSITEIT VAN AMSTERDAM
Call Details Starting Grant (StG), SH2, ERC-2011-StG_20101124
Summary "This project will undertake a transnational, multi-sited ethnographic study of moral and political subjectivity in HIV/AIDS prevention and treatment programs from the perspective of socio-cultural anthropology. The main research question is: what kinds of politico-moral persons are constituted in institutional contexts that combine human rights and personal responsibility approaches to health, and how these kinds of subjectivities relate to local, national, and global forms of the politico-moral represented in health policies? In particular, this research will be carried out in Indonesia (Jakarta and Bali), South Africa (Western Cape), USA (New York City), and various locations throughout Eastern Europe in HIV/AIDS programs and institutions that increasingly combine human rights and personal responsibility approaches to treatment and prevention. This project is the first anthropological research on health governance done on a global scale. Until now most anthropological studies have focused on one health program in one location without simultaneously studying similar processes in comparable contexts in other parts of the world. In contrast, this project will take a global perspective on the relationship between health issues, morality, and governance by doing transnational multi-sited research. This project will significantly contribute to the current anthropological focus on bio-citizenship and push it in new directions, resulting in a new anthropological theory of global bio-political governance and global politico-moral subjectivities. This theory will describe and explain recent transnational processes of shaping particular kinds of politico-moral subjectivities through health initiatives. By doing research in comparable world areas this project will significantly contribute to the development of a theory of politico-moral governance with global reach."

Call Details Advanced Grant (AdG), PE6, ERC-2016-ADG
Summary Our field is cryptology. Our overarching objective is to advance significantly the frontiers in
design and analysis of high-security cryptography for the future generation.
Particularly, we wish to enhance the efficiency, functionality, and, last-but-not-least, fundamental understanding of cryptographic security against very powerful adversaries.
Our approach here is to develop completely novel methods by
deepening, strengthening and broadening the
algebraic foundations of the field.
Concretely, our lens builds on
the arithmetic codex. This is a general, abstract cryptographic primitive whose basic theory we recently developed and whose asymptotic part, which relies on algebraic geometry, enjoys crucial applications in surprising foundational results on constant communication-rate two-party cryptography. A codex is a linear (error correcting) code that, when endowing its ambient vector space just with coordinate-wise multiplication, can be viewed as simulating, up to some degree, richer arithmetical structures such as finite fields (or products thereof), or generally, finite-dimensional algebras over finite fields. Besides this degree, coordinate-localities for which simulation holds and for which it does not at all are also captured.
Our method is based on novel perspectives on codices which significantly
widen their scope and strengthen their utility. Particularly, we bring
symmetries, computational- and complexity theoretic aspects, and connections with algebraic number theory, -geometry, and -combinatorics into play in novel ways. Our applications range from public-key cryptography to secure multi-party computation.
Our proposal is subdivided into 3 interconnected modules:
(1) Algebraic- and Number Theoretical Cryptanalysis
(2) Construction of Algebraic Crypto Primitives
(3) Advanced Theory of Arithmetic Codices

Project Anaerobic ammonium oxidizing bacteria: unique prokayotes with exceptional properties
Researcher (PI) Michael Silvester Maria Jetten
Host Institution (HI) STICHTING KATHOLIEKE UNIVERSITEIT
Call Details Advanced Grant (AdG), LS8, ERC-2008-AdG
Summary For over a century it was believed that ammonium could only be oxidized by microbes in the presence of oxygen. The possibility of anaerobic ammonium oxidation (anammox) was considered impossible. However, about 10 years ago the microbes responsible for the anammox reaction were discovered in a wastewater plant. This was followed by the identification of the responsible bacteria. Recently, the widespread environmental occurrence of the anammox bacteria was demonstrated leading to the realization that anammox bacteria may play a major role in biological nitrogen cycling. The anammox bacteria are unique microbes with many unusual properties. These include the biological turn-over of hydrazine, a well known rocket fuel, the biological synthesis of ladderane lipids, and the presence of a prokaryotic organelle in the cytoplasma of anammox bacteria. The aim of this project is to obtain a fundamental understanding of the metabolism and ecological importance of the anammox bacteria. Such understanding contributes directly to our environment and economy because the anammox bacteria form a new opportunity for nitrogen removal from wastewater, cheaper, with lower carbon dioxide emissions than existing technology. Scientifically the results will contribute to the understanding how hydrazine and dinitrogen gas are made by the anammox bacteria. The research will show which gene products are responsible for the anammox reaction, and how their expression is regulated. Furthermore, the experiments proposed will show if the prokaryotic organelle in anammox bacteria is involved in energy generation. Together the environmental and metabolic data will help to understand why anammox bacteria are so successful in the biogeochemical nitrogen cycle and thus shape our planets atmosphere. The different research lines will employ state of the art microbial and molecular methods to unravel the exceptional properties of these highly unusual and important anammox bacteria.

Summary Computer animation has traditionally been associated with applications in virtual-reality-based training, video games or feature films. However, interactive animation is gaining relevance in a more general scope, as a tool for early-stage analysis, design and planning in many applications in science and engineering. The user can get quick and visual feedback of the results, and then proceed by refining the experiments or designs. Potential applications include nanodesign, e-commerce or tactile telecommunication, but they also reach as far as, e.g., the analysis of ecological, climate, biological or physiological processes.
The application of computer animation is extremely limited in comparison to its potential outreach due to a trade-off between accuracy and computational efficiency. Such trade-off is induced by inherent complexity sources such as nonlinear or anisotropic behaviors, heterogeneous properties, or high dynamic ranges of effects.
The Animetrics project proposes a modeling and animation methodology, which consists of a multi-scale decomposition of complex processes, the description of the process at each scale through combination of simple local models, and fitting the parameters of those local models using large amounts of data from example effects. The modeling and animation methodology will be explored on specific problems arising in complex mechanical phenomena, including viscoelasticity of solids and thin shells, multi-body contact, granular and liquid flow, and fracture of solids.

Summary In the past decades, there has been a considerable rise in the number of apologies offered by states for injustices and human rights violations. Among transitional justice scholars, there is significant debate about how useful such apologies are. Whereas some have applauded these gestures as an important step in peacemaking processes, others have argued that they may not fit in all cultures and may even be a risky tool for peacemaking. Unfortunately, theorizing and research in the field of transitional justice is still in its infancy and has not systematically addressed questions of cross-cultural variability yet. So, at present, we do not know whether political apologies are a universally viable way to restore justice and harmony. My project addresses this challenge. Using an innovative, interdisciplinary, and multi-method approach with in-depth interviews, (experimental) surveys, and content analyses of apologies, I analyze whether there are universals in how political apologies are valued, expressed, and interpreted or whether this varies as a function of cross-cultural differences in key values (collectivism and individualism) and norms (face and honor). Based on these findings, I build a theoretical framework that will fundamentally advance our understanding of the potential value and role of apologies in transitional justice processes. This project breaks new ground because it is the first to take the difficult step to collect cross-cultural data to examine whether key assumptions regarding political apologies hold across cultures. It is also the first in this area to use a multi-method approach, which makes it possible to take into account the complex reality of political apologies. Combining insights from transitional justice, cross-cultural psychology and anthropology, this project places theorizing on transitional justice on a much firmer footing and paves the way to more cross-culturally valid models to restore justice and promote reconciliation.

Project A Unified Theory of Algorithmic Relaxations
Researcher (PI) Albert Atserias Peri
Host Institution (HI) UNIVERSITAT POLITECNICA DE CATALUNYA
Call Details Consolidator Grant (CoG), PE6, ERC-2014-CoG
Summary For a large family of computational problems collectively known as constrained optimization and satisfaction problems (CSPs), four decades of research in algorithms and computational complexity have led to a theory that tries to classify them as algorithmically tractable vs. intractable, i.e. polynomial-time solvable vs. NP-hard. However, there remains an important gap in our knowledge in that many CSPs of interest resist classification by this theory. Some such problems of practical relevance include fundamental partition problems in graph theory, isomorphism problems in combinatorics, and strategy-design problems in mathematical game theory. To tackle this gap in our knowledge, the research of the last decade has been driven either by finding hard instances for algorithms that solve tighter and tighter relaxations of the original problem, or by formulating new hardness-hypotheses that are stronger but admittedly less robust than NP-hardness.
The ultimate goal of this project is closing the gap between the partial progress that these approaches represent and the original classification project into tractable vs. intractable problems. Our thesis is that the field has reached a point where, in many cases of interest, the analysis of the current candidate algorithms that appear to solve all instances could suffice to classify the problem one way or the other, without the need for alternative hardness-hypotheses. The novelty in our approach is a program to develop our recent discovery that, in some cases of interest, two methods from different areas match in strength: indistinguishability pebble games from mathematical logic, and hierarchies of convex relaxations from mathematical programming. Thus, we aim at making significant advances in the status of important algorithmic problems by looking for a general theory that unifies and goes beyond the current understanding of its components.

Summary The overarching research question of this project is: how is authoritarian rule affected by and responding to globalisation of (a) information and communication, (b) association, and (c) people movement? The wholly unpredicted series of revolts that recently spread across the Arab world suggests that the nature and sustainability of contemporary authoritarian rule are not well-understood. Openness to global ICT and media, international NGOs, and inflow and outflow of people have thrown up new challenges for authoritarian rulers in terms of how to control citizens. This project investigates changes in both the nature and the sustainability of authoritarian rule in relation to the erosion of decision-making autonomy at the state level posited by globalisation theorists.
In four sub-projects, this project will investigate:
1. Whether, how and to what extent globalisation of information and communication, association, and people movement affect authoritarian persistence (longitudinal quantitative study, 1970-2011)
2. How, i.e. with what policy mechanisms, authoritarian states respond to globalisation of information and communication, association, and people movement (qualitative multi-sited studies relating to Belarus, China, Iran and Zimbabwe)
3. How to understand the phenomenon of subnational authoritarianism in its engagement with the democratic state and the wider world in relation to information and communication, association, and people movement (mixed method subnational studies of states within India and Mexico)
4. What authoritarianism is in a global age: reconsidering authoritarianism’s defining characteristics of low accountability and high coercion, and whether these still relate exclusively to statehood (theory study)
The project will transcend the theoretical and empirical separation between globalisation studies (which have neglected authoritarian contexts) and authoritarianism studies(which have taken relatively little notice of effects of globalisation)

Project The role of the virome in shaping the gut ecosystem during the first year of life
Researcher (PI) Alexandra Petrovna ZHERNAKOVA
Host Institution (HI) ACADEMISCH ZIEKENHUIS GRONINGEN
Call Details Starting Grant (StG), LS8, ERC-2016-STG
Summary The role of intestinal bacteria in human health and disease has been intensively studied; however the viral composition of the microbiome, the virome, remains largely unknown. As many of the viruses are bacteriophages, they are expected to be a major factor shaping the human microbiome. The dynamics of the virome during early life, its interaction with host and environmental factors, is likely to have profound effects on human physiology. Therefore it is extremely timely to study the virome in depth and on a wide scale.
This ERC project aims at understanding how the gut virome develops during the first year of life and how that relates to the composition of the bacterial microbiome. In particular, we will determine which intrinsic and environmental factors, including genetics and the mother’s microbiome and diet, interact with the virome in shaping the early gut microbiome ecosystem. In a longitudinal study of 1,000 newborns followed at 7 time points from birth till age 12 months, I will investigate: (1) the composition and evolution of the virome and bacterial microbiome in the first year of life; (2) the role of factors coming from the mother and from the host genome on virome and bacterial microbiome development and their co-evolution; and (3) the role of environmental factors, like infectious diseases, vaccinations and diet habits, on establishing the virome and overall microbiome composition during the first year of life.
This project will provide crucial knowledge about composition and maturation of the virome during the first year of life, and its symbiotic relation with the bacterial microbiome. This longitudinal dataset will be instrumental for identification of microbiome markers of diseases and for the follow up analysis of the long-term effect of microbiota maturation later in life. Knowledge of the role of viruses in shaping the microbiota may promote future directions for manipulating the human gut microbiota in health and disease.

Project acronym BALANCED LETHALS
Project Untangling the Evolution of a Balanced Lethal System
Researcher (PI) Biense WIELSTRA
Host Institution (HI) UNIVERSITEIT LEIDEN
Call Details Starting Grant (StG), LS8, ERC-2018-STG
Summary Natural selection is supposed to keep lethal alleles (dysfunctional or deleted copies of crucial genes) in check. Yet, in a balanced lethal system the frequency of lethal alleles is inflated. Because two forms of a chromosome carry distinct lethal alleles that are reciprocally compensated for by functional genes on the alternate chromosome form, both chromosome forms – and in effect their linked lethal alleles – are required for survival. The inability of natural selection to purge balanced lethal systems appears to defy evolutionary theory. How do balanced lethal systems originate and persist in nature? I suspect the answer to this pressing but neglected research question can be found in the context of supergenes in a balanced polymorphism – a current, hot topic in evolutionary biology. Chromosome rearrangements can lock distinct beneficial sets of alleles (i.e. supergenes) on two chromosome forms by suppressing recombination. Now, balancing selection would favour possession of both supergenes. However, as a consequence of suppressed recombination, unique lethal alleles could become fixed on each supergene, with natural selection powerless to prevent collapse of the arrangement into a balanced lethal system. I aim to explain the evolution of balanced lethal systems in nature. As empirical example I will use chromosome 1 syndrome, a balanced lethal system observed in newts of the genus Triturus. My research team will: Reconstruct the genomic architecture of this balanced lethal system at its point of origin [PI project]; Conduct comparative genomics with related, unaffected species [PhD project]; Determine gene order of the two supergenes involved [Postdoc project I]; and Model the conditions under which this balanced lethal system could theoretically have evolved [Postdoc project II]. Solving the paradox of chromosome 1 syndrome will allow us to understand balanced lethal systems in general and address the challenges they pose to evolutionary theory.

Project Women travelling to seek abortion care in Europe: the impact of barriers to legal abortion on women living in countries with ostensibly liberal abortion laws
Researcher (PI) Silvia De Zordo
Host Institution (HI) UNIVERSITAT DE BARCELONA
Call Details Starting Grant (StG), SH2, ERC-2015-STG
Summary In many European countries with ostensibly liberal abortion laws, women face legal restrictions to abortion beyond the first trimester of pregnancy, as well as other barriers to legal abortion, in particular shortages of providers willing and able to offer abortion due to poor training and to conscientious objection among physicians. The Council of Europe has recognized that conscientious objection can make access to safe abortion more difficult or impossible, particularly in rural areas and for low income women, who are forced to travel far to seek abortion care, including abroad. The WHO also highlights that delaying abortion care increases risks for women’s reproductive health. Despite the relevance of this topic from a public health and human rights perspective, the impact of procedural and social barriers to legal abortion on women in countries with ostensibly liberal abortion laws has not been studied by social scientists in Europe. This five-year research project is envisaged as a ground-breaking multi-disciplinary, mixed-methods investigation that will fill this gap, by capitalizing on previous, pioneer anthropological research of the PI on abortion and conscientious objection. It will contribute to the anthropology of reproduction in Europe, and particularly to the existing literature on abortion, conscientious objection and the medicalization of reproduction, and to the international debate on gender inequalities and citizenship, by exploring how barriers to legal abortion are constructed and how women embody and challenge them in different countries, by travelling or seeking illegal abortion, as well as their conceptualizations of abortion and their self perception as moral/political subjects. The project will be carried out in France, Italy and Spain, where the few existing studies show that women face several barriers to legal abortion as well as in the UK, the Netherlands and Spain, where Italian and French women travel to seek abortion care.

Project Towards a comparative sociology of beauty The transnational modelling industry and the social shaping of beauty standards in six European countries
Researcher (PI) Giselinde Maniouschka Marije Kuipers
Host Institution (HI) UNIVERSITEIT VAN AMSTERDAM
Call Details Starting Grant (StG), SH2, ERC-2009-StG
Summary This project studies how beauty standards - perceptions of physical beauty in women and men - are socially shaped. It will focus on the transnational modelling industry, an institution centrally concerned with the production and dissemination of beauty standards. The project aims to develop a comparative sociology of beauty. By comparing beauty standards both within and across nations, it will identify central mechanisms and institutions through which such standards are developed and disseminated. In 4 subprojects this study investigates 1. How standards of female and male beauty are perceived, shaped, and disseminated by professionals in the transnational modelling field; 2. How female and male models perceive, represent and embody beauty standards in their work; 3. How female and male beauty has been portrayed by models in mainstream and high fashion magazines from 1980 till 2010; 4. How people of different backgrounds perceive female and male beauty, and how their beauty standards are related to the images disseminated in modelling. Each project will be done in France, Italy, the Netherlands, Poland, Turkey and the UK. This project is innovative in several ways. It is the first comprehensive study of the social shaping of beauty standards. The 4 subprojects will result in an extensive account of production, products, and reception of a contested cultural industry. Moreover, this project draws together in novel ways theories about media, cultural production and taste formation; gender and the body; and globalization. The project will make a major contribution to the study of globalization: it studies a transnational cultural industry, and its comparative and longitudinal design allows us to gauge the impact of globalization in different contexts. Finally, the project is innovative in its comparative, multi-method research design, in which the subprojects will follow the entire process of production and consumption in a transnational field.

Project Becoming Men: Performing responsible masculinities in contemporary urban Africa
Researcher (PI) Eileen Marie Moyer
Host Institution (HI) UNIVERSITEIT VAN AMSTERDAM
Call Details Consolidator Grant (CoG), SH2, ERC-2014-CoG
Summary This anthropological study examines the reconfiguration of masculinities in urban Africa over the last 30 years. Focusing on how practices and discourses of empowerment and equality shape male subjectivities, this study builds upon a significant body of nuanced research on masculinities in Africa. Since the mid-1980s academic and public discourses have depicted African masculinity as both precarious and predatory. Economic insecurity, urbanization, shifting gender norms, and growing gender parity have accompanied claims that African masculinity is ‘in crisis’. More recently, new stories of urban men embracing responsible fatherhood, condemning intimate partner violence, and demanding homosexual rights have emerged as exemplars of progressive possibility. To disentangle these seemingly competing claims about African masculinities and shed light on the scientific, political, and economic projects that shape them, this research theorises that the discourses and practices that pathologise and politicise masculinity are simultaneously performing and producing gendered selves on multiple scales in the name of gender equality. Recently, ‘male involvement’ has become a rallying cry throughout the vast global development assemblage, around which governments, NGOs, research networks, activists, and local communities fight gender inequality to promote health, economic development, and human rights. In this research, a range of male-involvement initiatives provides a lens through which to study how masculinities are diversely imagined, (re)configured, and performed through men’s engagements with this assemblage, in both its local and global manifestations. Multi-sited ethnographic research will focus on six cities where the PI has active research ties: Nairobi and Kisumu, Kenya; Johannesburg and Durban, South Africa; and Dar es Salaam and Mwanza, Tanzania.

Project New discrete choice theory for understanding moral decision making behaviour
Researcher (PI) Caspar Gerard CHORUS
Host Institution (HI) TECHNISCHE UNIVERSITEIT DELFT
Call Details Consolidator Grant (CoG), SH2, ERC-2016-COG
Summary Discrete choice theory provides a mathematically rigorous framework to analyse and predict choice behaviour. While many of the theory’s key developments originate from the domain of transportation (mobility, travel behaviour), it is now widely used throughout the social sciences.
The theory has a blind spot for moral choice behaviour. It was designed to analyse situations where people make choices that are optimal given their consumer preferences, rather than situations where people attempt to make choices that are right, given their moral preferences. This neglect of the morality of choice is striking, in light of the fact that many of the most important choices people make, have a moral dimension.
This research program extends discrete choice theory to the domain of moral decision making.
It will produce a suite of new mathematical representations of choice behaviour (i.e., choice models), which are designed to capture the decision rules and decision weights that determine how individuals behave in moral choice situations. In these models, particular emphasis is given to heterogeneity in moral decision rules and to the role of social influences. Models will be estimated and validated using data obtained through a series of interviews, surveys and choice experiments. Empirical analyses will take place in the context of moral choice situations concerning i) co-operative road using and ii) unsafe driving practices. Estimation results will be used as input for agent based models, to identify how social interaction processes lead to the emergence, persistence or dissolution of moral (traffic) equilibria at larger spatio-temporal scales.
Together, these proposed research efforts promise to generate a major breakthrough in discrete choice theory. In addition, the program will result in important methodological contributions to the empirical study of moral decision making behaviour in general; and to new insights into the moral aspects of (travel) behaviour.

Project Biotic community attributes and ecosystem functioning: implications for predicting and mitigating global change impacts
Researcher (PI) Fernando Tomás Maestre Gil
Host Institution (HI) UNIVERSIDAD REY JUAN CARLOS
Call Details Starting Grant (StG), LS8, ERC-2009-StG
Summary Increases in nutrient availability and temperature, and changes in precipitation patterns and biodiversity are important components of global environmental change. Thus, it is imperative to understand their impacts on the functioning of natural ecosystems. Substantial research efforts are being currently devoted to predict how biodiversity will respond to global change. However, little is known on the relative importance of biodiversity against other attributes of biotic communities, such as species cover and spatial pattern, as a driver of ecosystem processes. Furthermore, the effects of global change on the relationships between these attributes and ecosystem functioning are virtually unknown. This project aims to evaluate the relationships between community attributes (species richness, composition, evenness, cover, and spatial pattern) and key processes related to ecosystem functioning under different global change scenarios. Its specific objectives are to: i) evaluate the relative importance of community attributes as drivers of ecosystem functioning, ii) assess how multiple global change drivers will affect key ecosystem processes, iii) test whether global change drivers modify observed community attributes-ecosystem functioning relationships, iv) develop models to forecast global change effects on ecosystem functioning, and v) set up protocols for the establishment of mitigation actions based on the results obtained. They will be achieved by integrating experimental and modeling approaches conducted with multiple biotic communities at different spatial scales. Such integrated framework has not been tackled before, and constitutes a ground breaking advance over current research efforts on global change. This proposal will also open the door to new research lines exploring the functional role of community attributes and their importance as modulators of ecosystem responses to global change.

Researcher (PI) Fernando Tomás Maestre Gil
Host Institution (HI) UNIVERSIDAD DE ALICANTE
Call Details Consolidator Grant (CoG), LS8, ERC-2014-CoG
Summary Changes in climate and land use (e.g., increased grazing pressure), are two main global change components that also act as major desertification drivers. Understanding how drylands will respond to these drivers is crucial because they occupy 41% of the terrestrial surface and are home to over 38% of the world’s human population. Land degradation already affects ~250 million people in the developing world, which rely upon the provision of many ecosystem processes (multifunctionality). This proposal aims to develop a better understanding of the functioning and resilience of drylands (i.e. their ability to respond to and recover from disturbances) to major desertification drivers. Its objectives are to: 1) test how changes in climate and grazing pressure determine spatiotemporal patterns in multifunctionality in global drylands, 2) assess how biotic attributes (e.g., biodiversity, cover) modulate ecosystem resilience to climate change and grazing pressure at various spatial scales, 3) test and develop early warning indicators of desertification, and 4) forecast the onset of desertification and its ecological consequences under different climate and grazing scenarios. I will use various biotic communities/attributes, ecosystem services and spatial scales (from local to global), and will combine approaches from several disciplines. Such comprehensive and highly integrated research endeavor is novel and constitutes a ground breaking advance over current research efforts on desertification. This project will provide a mechanistic understanding on the processes driving multifunctionality under different global change scenarios, as well as key insights to forecast future scenarios for the provisioning of ecosystem services in drylands, and to test and develop early warning indicators of desertification. This is of major importance to attain global sustainability and key Millennium Development Goals, such as the eradication of poverty.

Project Monitoring Biodiversity from Space

Call Details Advanced Grant (AdG), SH2, ERC-2018-ADG
Summary Life, with all its diversity, is in crisis. As humans increasingly encroach on biologically complex semi- natural landscapes, no organism, place or ecological function remains unaffected. While all 196 parties (195 countries plus the European Union) to the UN Convention on Biodiversity (CBD) have agreed to monitor the state of biodiversity, the currently available methods to do so leave much to be desired. Traditional monitoring involves the field observation of species by trained specialists, aided by skilled volunteers, whose expertise is restricted to specific biotic groupings. In a process that is both time consuming and inconsistent across time and space, botanists identify and record the presence of plant species and ornithologists the bird biota, resulting in 'unpopular' biotic groups such as fungi, bacteria and insects being under-observed or escaping identification altogether. In this project, a fundamentally different approach to terrestrial biodiversity monitoring couples next generation satellite remote sensing with environmental DNA (eDNA) profiling, complemented where available by legacy human-observed datasets. Satellite remote sensing is able to survey the environment as a single, continuous, fine-resolution map, while eDNA profiling can rapidly quantify much greater taxonomical and functional breadth and depth than human field observation. This project combines, for the first time, these two powerful, cutting-edge techniques for monitoring biodiversity at the global level in a consistent manner. Following from this, another key innovation will be the deepening of our scientific understanding of how biodiversity is impacted by anthropogenic pressure as well as by natural environmental gradients. In concert, these scientific developments will enable the accurate and fine grain monitoring of biodiversity from space – a ground-breaking contribution to the quest to meet the UN Sustainable Development Goals and CBD Aichi targets.

Project Optical dissection of circuits underlying fast cholinergic signalling during cognitive behaviour

Host Institution (HI) STICHTING VU
Call Details Starting Grant (StG), LS5, ERC-2011-StG_20101109
Summary Our ability to think, to memorize and focus our thoughts depends on acetylcholine signaling in the brain. The loss of cholinergic signalling in for instance Alzheimer’s disease strongly compromises these cognitive abilities. The traditional view on the role of cholinergic input to the neocortex is that slowly changing levels of extracellular acetylcholine (ACh) mediate different arousal states. This view has been challenged by recent studies demonstrating that rapid phasic changes in ACh levels at the scale of seconds are correlated with focus of attention, suggesting that these signals may mediate defined cognitive operations. Despite a wealth of anatomical data on the organization of the cholinergic system, very little understanding exists on its functional organization. How the relatively sparse input of cholinergic transmission in the prefrontal cortex elicits such a profound and specific control over attention is unknown. The main objective of this proposal is to develop a causal understanding of how cellular mechanisms of fast acetylcholine signalling are orchestrated during cognitive behaviour.
In a series of studies, I have identified several synaptic and cellular mechanisms by which the cholinergic system can alter neuronal circuitry function, both in cortical and subcortical areas. I have used a combination of behavioral, physiological and genetic methods in which I manipulated cholinergic receptor functionality in prefrontal cortex in a subunit specific manner and found that ACh receptors in the prefrontal cortex control attention performance. Recent advances in optogenetic and electrochemical methods now allow to rapidly manipulate and measure acetylcholine levels in freely moving, behaving animals. Using these techniques, I aim to uncover which cholinergic neurons are involved in fast cholinergic signaling during cognition and uncover the underlying neuronal mechanisms that alter prefrontal cortical network function.

The traditional view on the role of cholinergic input to the neocortex is that slowly changing levels of extracellular acetylcholine (ACh) mediate different arousal states. This view has been challenged by recent studies demonstrating that rapid phasic changes in ACh levels at the scale of seconds are correlated with focus of attention, suggesting that these signals may mediate defined cognitive operations. Despite a wealth of anatomical data on the organization of the cholinergic system, very little understanding exists on its functional organization. How the relatively sparse input of cholinergic transmission in the prefrontal cortex elicits such a profound and specific control over attention is unknown. The main objective of this proposal is to develop a causal understanding of how cellular mechanisms of fast acetylcholine signalling are orchestrated during cognitive behaviour.
In a series of studies, I have identified several synaptic and cellular mechanisms by which the cholinergic system can alter neuronal circuitry function, both in cortical and subcortical areas. I have used a combination of behavioral, physiological and genetic methods in which I manipulated cholinergic receptor functionality in prefrontal cortex in a subunit specific manner and found that ACh receptors in the prefrontal cortex control attention performance. Recent advances in optogenetic and electrochemical methods now allow to rapidly manipulate and measure acetylcholine levels in freely moving, behaving animals. Using these techniques, I aim to uncover which cholinergic neurons are involved in fast cholinergic signaling during cognition and uncover the underlying neuronal mechanisms that alter prefrontal cortical network function.
