Introduction
I am a molecular ecologist and conservation geneticist interested in how the genetic variation of multiple species is distributed in space and time: Are there general patterns of genetic variation? Which processes influence them? What are their implications for biodiversity conservation? With colleagues from the Powell Center Conservation Genetics / Genomics Working Group, we aim at tackling these questions using macrogenetic approaches.

Article
Full-text available
The COVID‐19 pandemic has heavily impacted academics’ professional and personal lives, forcing many research groups (labs) to shift from an academic system primarily based on in‐person work to an almost full‐time remote workforce during lockdowns. Labs are generally characterized by a strong lab culture that underpins all research and social activi...
Article
Full-text available
Biodiversity underlies ecosystem resilience, ecosystem function, sustainable economies, and human well‐being. Understanding how biodiversity sustains ecosystems under anthropogenic stressors and global environmental change will require new ways of deriving and applying biodiversity data. A major challenge is that biodiversity data and knowledge are...
Article
1‐ The efficient management of Invasive Alien Species (IAS) requires the identification of their introduction pathways. Genetic assessments have proven useful to inform invasion pathways at large (national to worldwide) scales but studies at local scales are still rare, despite their importance for guiding management. 2‐ In this study, genetic anal...

Genetic diversity is critically important for all species-domesticated and wild- to adapt to environmental change, and for ecosystem resilience to extreme events. International agreements such as the Convention on Biological Diversity (CBD) have committed to conserve and sustainably and equitably use all levels of biodiversity-genes, species and ec...
Article
Full-text available
We believe the 20 species extinction metric is a retrograde proposal, which does not adequately consider the lessons learnt from the 2020 Aichi Biodiversity Targets. Whilst having a single simple overarching target is appealing, we believe a positively-framed target will garner support, rather than one that aims to, at best, limit negative impacts....

Full-text available
The 196 parties to the Convention on Biological Diversity (CBD) will soon agree to a post-2020 global framework for conserving the three elements of biodiversity (genetic, species, and ecosystem diversity) while ensuring sustainable development and benefit sharing. As the most significant global conservation policy mechanism, the new CBD framework...
Article
Full-text available
Rivers are fascinating ecosystems in which the eco-evolutionary dynamics of organisms are constrained by particular features, and biologists have developed a wealth of knowledge about freshwater biodiversity patterns. Over the last ten years, our group used a holistic approach to contribute to this knowledge by focusing on the causes and consequenc...
Article
Teleost fishes interact with diverse microbial communities, playing crucial functions for host fitness. While gut microbiome has been extensively studied, skin microbiome has been overlooked. Specifically, there is no assessment of the relative impact of host and environmental factors on microbiome variability as well as neutral processes shaping f...
Article
Unraveling the relationship between demographic declines and genetic changes over time is of critical importance to predict the persistence of at‐risk populations and to propose efficient conservation plans. This is particularly relevant in spatially structured populations (i.e. metapopulations) in which the spatial arrangement of local populations...

The European catfish (Silurus glanis) is the largest freshwater fish in Europe. In France, where the catfish has been widely introduced, it reaches more than twice the size of native predators such as pike, which has the effect of increasing the maximum size at which preys are no longer predated. Fish species (e.g. migratory species) that previousl...
Article
Full-text available
Intraspecific diversity informs the demographic and evolutionary histories of populations, and should be a main conservation target. Although approaches exist for identifying relevant biological conservation units, attempts to identify priority conservation areas for intraspecific diversity are scarce, especially within a multi-specific framework....
Article
Full-text available
Identifying landscape features that affect functional connectivity among populations is a major challenge in fundamental and applied sciences. Landscape genetics combines landscape and genetic data to address this issue, with the main objective of disentangling direct and indirect relationships among an intricate set of variables. Causal modeling h...

Article
1. Species-genetic diversity correlations (SGDCs) have been investigated over a large spectra of organisms, which has greatly improved our understanding of parallel processes potentially driving both species and genetic diversity. However, there are still few studies comparing SGDCs (and underlying processes) for multiple species sampled over a sin...
Article
Full-text available
Emerging pathogens constitute a severe threat for human health and biodiversity. Determining the status (native or non-native) of emerging pathogens, and tracing back their spatio-temporal dynamics is crucial to understand the eco-evolutionary factors promoting their emergence, to control their spread and mitigate their impacts. However, tracing ba...
Article
Full-text available
Describing, understanding and predicting the spatial distribution of genetic diversity is a central issue in biological sciences. In river landscapes, it is generally predicted that neutral genetic diversity should increase downstream, but there have been few attempts to test and validate this assumption across taxonomic groups. Moreover, it is sti...
Article
Full-text available
Landscape features notoriously affect spatial patterns of biodiversity. For instance, in dendritic ecological networks (such as river basins), dendritic connectivity has been proposed to create unique spatial patterns of biodiversity. Here, we compared genetic datasets simulated under a lattice-like, a dendritic and a circular landscape to test the...
Thesis
Full-text available
The objective of this thesis is to characterize the distribution of genetic diversity in dendritic networks. First, we identify a general spatial pattern of genetic diversity on these ecosystems, as well as the effects of asymmetric gene flow, differential in effective population sizes and colonization processes on this pattern. Second, we characte...

Full-text available
Molecular genetic techniques have been used in freshwater biology for more than 30 years. Early work focussed on studies of population structure, systematics and taxonomy. More recently, the range of studies has broadened to include ecology and adaptation. Advances in analytical methods and in technology (e.g. next-generation sequencing) and decrea...
Article
Full-text available
Prioritizing and making efficient conservation plans for threatened populations requires information at both evolutionary and ecological timescales. Nevertheless, few studies integrate multidisciplinary approaches, mainly because of the difficulty for conservationists to assess simultaneously the evolutionary and ecological status of populations. H...
Article
Full-text available
Population structure can significantly affect genetic-based demographic inferences, generating spurious bottleneck-like signals. Previous studies have typically assumed island or stepping-stone models, which are characterized by symmetric gene flow. However, many organisms are characterized by asymmetric gene flow. Here, we combined simulated and e...

Although being a widely introduced and successfully established species, the European catfish Silurus glanis L., one of the world’s largest freshwater fish, remains poorly studied in its introduced areas. Specifically, our group aims to bring scientific information on biology and ecology of this species in a broad context (from local to international area studies and from populations to individual levels). The European catfish is also seen as a multidisciplinary model, for instance the extreme body size of this species implies novel behaviors and new questions that stimulate cross-sectional researches (e.g., bioacoustics; informatics; microbiology; social science). Some research questions: - What is the relationship between ecosystem anthropization and the survival, establishment and invasion probability of European catfish? - How do individual differences in behaviour and personality influence the ability of released European catfish individuals to disperse, to establish new populations and to colonise new regions? - Can recreation of the pathways of introduction via genetic analyses help characterise the influence of donor regions on invasive outcomes, including adaptation processes?

Project duration: 2010-2013 The IWRM-NET IMPACT project is developing a model framework to disentangle and assess the effect of anthropogenic stressors on river biota (invertebrates and fish). The main objective of the project IMPACT is to assess the relative importance of anthropogenic pressures operating at different spatial scales, to identify the main bottlenecks for river biota by coupling models, and to answer the following research questions: +) What can you expect from local reach-scale restoration given the remaining pressures on larger spatial scales? + ) How important are discharge changes due to Climate Change compared to other anthropogenic pressures? +) Will Climate Change have a major influence on natural reference conditions?
