Project Bacterial cooperation at the individual cell level

Host Institution (HI) UNIVERSITAT ZURICH
Call Details Consolidator Grant (CoG), LS8, ERC-2015-CoG
Summary All levels of life entail cooperation and conflict. Genes cooperate to build up a functional genome, which can yet be undermined by selfish genetic elements. Humans and animals cooperate to build up societies, which can yet be subverted by cheats. There is a long-standing interest among biologists to comprehend the tug-of-war between cooperation and conflict. Recently, research on bacteria was successful in identifying key factors that can tip the balance in favour or against cooperation. Bacteria cooperate through the formation of protective biofilms, cell-to-cell communication, and the secretion of shareable public goods. However, the advantage of bacteria being fast replicating units, easily cultivatable in high numbers, is also their disadvantage: they are small and imperceptible, such that measures of cooperation typically rely on averaged responses across millions of cells. Thus, we still know very little about bacterial cooperation at the biological relevant scale: the individual cell level. Here, I present research using the secretion of public goods in the opportunistic human pathogen Pseudomonas aeruginosa, to tackle this issue. I will explore new dimensions of bacterial cooperation by asking whether bacteria engage in collective-decision making to find optimal group-level solutions; whether bacteria show division of labour to split up work efficiently; and whether bacteria can distinguish between trustworthy and cheating partners. The proposed research will make two significant contributions. First, it will reveal whether bacteria engage in complex forms of cooperation (collective decision-making, division of labour, partner recognition), which have traditionally been associated with higher organisms. Second, it will provide insights into the evolutionary stability of cooperation – key knowledge for designing therapies that interfere with virulence-inducing public goods in infections, and the design of stable public-good based remediation processes.

Project Towards a decentred history of the Middle East: Transborder spaces, circulations, frontier effects and state formation, 1920-1946
Researcher (PI) Jordi TEJEL GORGAS
Host Institution (HI) UNIVERSITE DE NEUCHATEL
Call Details Consolidator Grant (CoG), SH6, ERC-2016-COG
Summary While the crisis of the territorial nation-state in the Middle East has once again been brought to a head by the wars in Iraq and Syria, it cannot be simply understood as the logical consequence of an imported political construction. Based on two epistemological notions – borderlands as histoire-problème (history-as-problem) and the co-production of borders between state and society – this research project proposes to rethink the classical historical narrative about the emergence of the post-Ottoman Middle East. Taking its cue from trans-border phenomena and thus paying attention to the circulation of people, goods and ideas as well as to everyday encounters between local actors and state representatives, the project will be guided by four principle objectives to offer:
• A socio-historical analysis of state violence in the borderlands of the Middle East;
• An examination of the capacity of border populations to create the history of the borderlands, nation-states, and the region as a whole;
• A study of the frontier effects based around the notions of subjectivity, space and time, and involving various levels of observation (macro, meso and micro) in order to identify the ruptures and continuities evoked by the delineation of new borderlines; and
• A historical lens through which to make sense of current events in Syria and Iraq, and possibly orient conflict-resolution practitioners.
Through the exploitation of a wide range of sources (diplomatic, administrative and military records, missionary documents, newspapers) and by looking at the social construction of international frontiers at the borderlands located between Turkey, Iraq and Syria in the interwar era, the research project will provide a much more holistic yet finely-grained understanding of the formation of the territorial state in the region in the aftermath of the First World War as well as a historical perspective on the on-going armed conflicts.

Project Characterizing Adaptation and Migration Events with Modern and Ancient Genomes
Researcher (PI) Anna-Sapfo Malaspinas
Host Institution (HI) UNIVERSITAET BERN
Call Details Starting Grant (StG), LS8, ERC-2015-STG
Summary BACKGROUND Ancient DNA research has recently entered the genomics era. Performing “ancient population genomics” is now technically possible. Utilizing the temporal aspect of this new data, we can address fundamental evolutionary questions such as the amount of selection acting on the genome or the mode and tempo of the colonization of the world. AIMS The overall goal of the proposed research is to (i) generate and analyse data to answer two long standing questions in human evolution: understanding the molecular basis of human adaptation to high altitude and investigating the timing of the Polynesian-South American contact, (ii) develop statistical approaches that combine ancient and modern genetic data to estimate the timing and the intensity of a selective sweep and an admixture event. METHODOLOGY Application: We will collect, date and DNA sequence human remains. Combining the ancient genetic data, 14C dates with existing modern genomic data will allow us to increase the resolution as to the timing of the adaptive and the admixture event, respectively, while generating unique datasets. Theory: We will build on existing methods based on one-locus classical population genetic models to develop tools to analyse whole genome time serial data. RELEVANCE Ecological: The results will address the fundamental question of how much of the human genome is undergoing selection, better characterize one of the textbook examples of adaptation in humans and contribute to our understanding of the peopling of the Americas. Medical: We will gain insights into the fundamental stress physiology experienced at high altitude and therefore into altitude-related illnesses. Methodological: The methods developed in this project will not only benefit the growing field of ancient genomics but also other fields where data is collected in a temporal manner, such as experimental evolution and epidemiology

Host Institution (HI) UNIVERSITAT BASEL
Call Details Consolidator Grant (CoG), LS8, ERC-2013-CoG
Summary "More than 150 years after the publication of Charles Darwin’s The Origin of Species, the identification of the processes that govern the emergence of novel species remains a fundamental problem to biology. Why is it that some groups have diversified in a seemingly explosive manner, while others have lingered unvaried over millions of years? What are the external factors and environmental conditions that promote organismal diversity? And what is the molecular basis of adaptation and diversification? A key to these and related questions is the comparative study of exceptionally diverse yet relatively recent species assemblages such as Darwin’s finches, the Caribbean anole lizards, or the hundreds of endemic species of cichlid fishes in the East African Great Lakes, which are at the center of this proposal. More specifically, I intend to conduct the so far most thorough examination of a large adaptive radiation, combining in-depth eco-morphological assessments and whole genome sequencing of all members of a cichlid species flock. To this end, I plan to (i) sequence the genomes and transcriptomes of several specimens of each cichlid species from Lake Tanganyika to examine genetic and transcriptional diversity; (ii) apply stable-isotope and stomach-content analyses in combination with underwater transplant experiments and transect surveys to quantitate feeding performances, habitat preferences and natural-history parameters; (iii) use X-ray computed tomography to study phenotypic variation in 3D; and (iv) examine fossils from existing and forthcoming drilling cores to implement a time line of diversification in a cichlid adaptive radiation. This project, thus, offers the unique opportunity to test recent theory- and data-based predictions on speciation and adaptive radiation within an entire biological system – in this case the adaptive radiation of cichlid fishes in Lake Tanganyika."

Summary As evolutionary biologists we are of course motivated by the desire to gain further insight in to the evolution of natural populations. The main goals of this proposal are to (i) develop theory and methodology that will enable the identification of adaptively evolving genomic regions using polymorphism data, (ii) develop theory and methodology for the estimation of whole-genome rates of adaptive evolution, and (iii) apply the developed theory in two strategic collaborative applications. Capitalizing on recently available and soon-to-be available whole genome polymorphism data across multiple taxa, these approaches are expected to significantly improve the identification and localization of recent selective events, as well as provide long sought after information regarding the genomic distributions of selective effects. Additionally, through these on-going collaborations with empirical and experimental labs, this methodology will allow for specific hypothesis testing that will further illuminate classical examples of adaptation. Together, this proposal seeks to Describe Evolution with Theoretical, Empirical and Computational Tools (DETECT), seeking to accurately describe the very mode and tempo of Darwinian adaptation.

Project The Mass Politics of Disintegration
Researcher (PI) Stefanie Walter
Host Institution (HI) UNIVERSITAT ZURICH
Call Details Consolidator Grant (CoG), SH2, ERC-2018-COG
Summary In the past few years, there has been a growing popular backlash against international institutions. Examples include the 2015 Greek bailout referendum, the 2016 Brexit referendum, or the 2016 election of a US President seemingly determined to withdraw US support from various international treaties. The implications of these mass-based disintegration efforts reach far beyond the countries in which they originate. First, the disintegration process is shaped by how remaining member states respond to one member’s bid to unilaterally change or terminate the terms of an existing international agreement. Second, mass-based disintegration bids pose considerable political contagion risks by encouraging disintegrative tendencies in other countries. Unfortunately, our theoretical tools to understand such international disintegration processes are underdeveloped. DISINTEGRATION therefore conducts a broad, systematic, and comparative inquiry into the mass politics of disintegration that pays particular attention to reactions in the remaining member states. It explores when and how one country’s mass-based disintegration experience encourages or deters demands for disintegration in other countries, how these contagion effects are transmitted through domestic elites and domestic discourse, and how the remaining member states ultimately respond during disintegration negotiations. It undertakes large-scale multi-method data collection that exploits the research opportunities offered by two ongoing mass-based disintegration processes: the Brexit negotiations and an upcoming Swiss referendum aimed at terminating a Swiss-EU bilateral treaty. DISINTEGRATION’s main objective is to develop a much-needed theory of mass-based disintegration that helps us understand the transnational dynamics that unfold between governments, political elites and the mass public when one member state attempts to unilaterally withdraw from an international agreement on the basis of widespread popular support.

Project How God Became a Lawgiver: The Place of the Torah in Ancient Near Eastern Legal History
Researcher (PI) Konrad Schmid
Host Institution (HI) UNIVERSITAT ZURICH
Call Details Advanced Grant (AdG), SH6, ERC-2018-ADG
Summary The Torah’s notion of divine law fundamentally transforms the nature of law found in its ancient Near Eastern context. Typically kings—not gods—took on the role of the promulgation of laws. The Torah’s conception of God as lawgiver emerged gradually through historical processes, rather than constituting the bedrock of the Bible’s literary and legal history. And, while scholars have long recognized the uniqueness of the Torah’s conception, its early historical development has received little attention. Only tangential analysis exists on the forces surrounding the genesis of the Torah’s notion of divine laws within ancient Near Eastern legal history or its impact on religion and politics in the early historical contexts of ancient Israel and Judah.
This project therefore aims: 1) to explicate the anchoring of law in the religious ether of the Ancient Near East; 2) to elucidate for the first time the intellectual processes in ancient Israel and Judah that led to the notion of divine laws and God as lawgiver, drawing comparisons with other legal understandings and practices from the ancient Near East; 3) to assess the socio-political and religious impact of this notion with ancient Judaism through the Hellenistic Period; and 4) to contextualize this development in the ancient world in comparison to parallel developments in Greek polities.
The project’s innovative potential lies in: 1) the evaluation of the divine laws as a historical phenomenon; 2) the neglected effort to understand their intellectual genesis and early development in a reciprocal relation to their socio-political context; 3) the cross-cultural analysis of ancient Israel and Judah and its neighbouring cultures in this regard; and 4) the application of a longue durée and realgeschichtliche perspective to largely literary and philological disciplines. These investigations offer a new paradigm for elucidating the webs connecting divinity, law, and socio-political developments in the first millennium BCE.

Project The Drosophila-Spiroplasma interaction as a model to dissect the molecular mechanisms underlying insect endosymbiosis
Researcher (PI) Bruno Lemaitre
Host Institution (HI) ECOLE POLYTECHNIQUE FEDERALE DE LAUSANNE
Call Details Advanced Grant (AdG), LS8, ERC-2013-ADG
Summary Virtually every species of insect harbors facultative bacterial endosymbionts that are transmitted from females to their offspring, often in the egg cytoplasm. These symbionts play crucial roles in the biology of their hosts. Many manipulate host reproduction in order to spread within host populations. Others increase the fitness of their hosts under certain conditions. For example, increasing tolerance to heat or protecting their hosts against natural enemies. Over the past decade, our understanding of insect endosymbionts has shifted from seeing them as fascinating oddities to being ubiquitous and central to the biology of their hosts, including many of high economic and medical importance. However, in spite of growing interest in endosymbionts, very little is known about the molecular mechanisms underlying most endosymbiont-insect interactions. For instance, the basis of the main phenotypes caused by endosymbionts, including diverse reproductive manipulations or symbiont-protective immunity, remains largely enigmatic. The goal of the present application is to fill this gap by dissecting the interaction between Drosophila and its native endosymbiont Spiroplasma poulsonii. This project will use a broad range of approaches ranging from molecular genetic to genomics to dissect the molecular mechanisms underlying key features of the symbiosis, including vertical transmission, male killing, regulation of symbiont growth, and symbiont-mediated protection against parasitic wasps. We believe that the fundamental knowledge generated on the Drosophila-Spiroplasma interaction will serve as a paradigm for other endosymbiont-insect interactions that are less amenable to genetic studies.

Summary In the face of the alarming pace of recent environmental change we lack the tools to accurately predict how biodiversity and ecosystem services will respond. One key gap in knowledge that limits our predictive ability is uncertainty concerning how the biotic interactions will change. Developing a predictive science of species interactions requires integrating evolutionary, biogeographic and ecological mechanisms acting at different spatial and temporal scales. We will use a hierarchical cross-scale approach, combining phylogeography, network ecology, statistical modelling and experiments, to disentangle the mechanisms governing species richness and mutualistic interactions in tropical hummingbirds and their food plants. Hummingbirds and their food plants are an excellent model system because they are highly diverse, highly specialized, and logistically feasible to study. Our objectives are to (1) evaluate the influence of factors, such as trait-matching, environmental conditions and relatedness, on network structure; (2) quantify how and why interaction beta-diversity (i.e., reflecting the change in both species composition, and in interacting partners) changes across elevation gradients in each of three biogeographic regions with distinct evolutionary histories (mountain regions in Costa Rica, Ecuador, Brazil); (3) evaluate the importance of multiple factors, such as trait-matching, environmental conditions, relatedness and abundance, on species interactions and network structure; and (4) develop a predictive model of species interactions and evaluate its performance using cross-validation and experimentation. Together, these tasks will provide new insight into one of the central enigmas in ecology, namely, why species diversity and its interaction architecture change across space and time. We will also be able predict how species interactions will change from present to the future, which is essential for the conservation of biodiversity and ecosystem services.

Host Institution (HI) UNIVERZA V LJUBLJANI
Call Details Advanced Grant (AdG), SH6, ERC-2016-ADG
Summary The EIRENE project’s purpose is to think afresh 20th-century post-war transitions by taking into account a gendered perspective. Namely, the historiographic consideration of gender thoroughly alters the understanding of social dynamics in multi-ethnic areas during the post-war transitions. They will be observed in the North-Eastern Adriatic region, an overlooked European space, marked by border redefinitions, changes of political systems, and high interethnic conflict intensity, but also by genuine cooperation among ethnic groups. The region has all the qualities of a “laboratory environment” for the study of gender positions and interrelations after World Wars I and II and after the Yugoslav wars in the 1990s. The project will differ substantially from previous attempts to analyse post-war transitions in these aspects: a) longitudinal approach, comparing three post-war periods in order to detect their specifics and (dis)continuities; b) transnational approach, by overcoming nation-centric frameworks of analysis; c) by combining conceptual political and social sciences with historiography; and finally, d) by examining post-war transitions through the prism of gender. Focusing on four research-fields (politics, political violence, work, family), the project will validate innovative analytical concepts of the “inclusion-exclusion paradox” of women in post-war transitions, and women as “cross-boundary mediators”. Within the category of gender, focal attention will be given to women as they are often invisible in historical accounts and remain neglected in historicizing. By aggregating empirical sources, the project will approach the proposed subject matter by investigating the processes of identification across the lines of ethnic origin, class, generations, marital status, profession/occupation, language of use, migratory processes, etc. The project’s added value is its novel conceptual applicability to other comparable geopolitical areas.

By aggregating empirical sources, the project will approach the proposed subject matter by investigating the processes of identification across the lines of ethnic origin, class, generations, marital status, profession/occupation, language of use, migratory processes, etc. The project’s added value is its novel conceptual applicability to other comparable geopolitical areas.
