Abstract Withstanding extinction while facing rapid climate change depends on a species’ ability to track its ecological niche or evolve new one. Current methods that predict climate-driven range shifts use modelling without eco-evolutionary dynamics. Here we present an forecasting framework combines with individual-based demographic and genetic simulations. Applying our approach four endemic perennial plant species of the Austrian Alps, show accounting for dynamics when predicting responses...
Many species facing climate change have complex life cycles, with individuals in different stages differing their sensitivity to a changing and contribution population growth. We use quantitative genetics model predict the dynamics of adaptation stage-structured confronted steadily environment. Our assumes that optimal phenotypic values maximize fitness components, consistent many empirical observations. In constant environment, evolves toward an equilibrium phenotype, which represents best...
Many natural populations exhibit temporal fluctuations in abundance that are consistent with external forcing by a randomly changing environment. As fitness emerges from an interaction between the phenotype and environment, such demographic probably include substantial contribution fluctuating phenotypic selection. We study stochastic population dynamics of exposed to random (plus possibly directional) changes optimum for quantitative trait evolves response this moving optimum. derive simple...
In this study, we use a quantitative genetics model of structured populations to investigate the evolution senescence in variable environment. Adaptation local environments depends on phenotypic traits whose optimal values vary with age and environmental conditions. We study different scenarios heterogeneity, where environment changes abruptly, gradually, or cyclically time is heterogeneous space connected by migration. The strength selection decreases age, which predicts slower adaptation...
Co-occurrence of multiple diseases and co-infection individual plants by various pathogens have potential epidemiological evolutionary implications. Based on previous information the co-occurrence rice yellow mottle disease (caused virus, RYMV) bacterial leaf streak (BLS, due to Xanthomonas oryzae pv. oryzicola, Xoc) in Burkina Faso, experimental evidence interactions between causing these two diseases, we aimed monitor more intensively farmers fields. To this purpose, selected fields...
Disease surveillance is a keystone of human, animal, and plant health. It contributes to the prevention management epidemics. Over past two decades, several methodological frameworks have been developed for evaluation human animal health systems, but such approaches are still lacking in Here, we aimed at providing one first evaluations pest system. We applied semi-quantitative OASIS method, already successfully used centralized health, French system sharka, viral disease Prunus trees. A...
The distribution of fitness effects (DFE) new mutations is key to our understanding many evolutionary processes. Theoreticians have developed several models help understand the patterns seen in empirical DFEs. Many such reproduce broad DFEs but these often rely on structural assumptions that cannot be tested empirically. Here, we investigate how much underlying "microscopic" biological processes involved mapping can inferred from "macroscopic" observations DFE. We develop a null model by...
Abstract Anticipating and preparing for the effect of environmental changes on biodiversity requires to understand predict both ecological evolutionary responses populations. Tools methods efficiently integrate these complex processes are lacking. We present genetically spatially explicit individual‐based simulation software Nemo‐age combining processes. has a strong emphasis modelling life histories. here provide methodology in species distribution given climate projections using ....
In recent years, theoretical models have introduced the concept that ongoing hybridization between "good" species can occur because incomplete reproductive isolation be a selected optimum. They furthermore show positive frequency-dependent sexual selection, which is naturally generated by some of underlying processes lead to assortative mating, plays key role in evolution isolation. This occurs, however, through different mechanisms sympatric versus allopatric scenarios. We investigate...
Abundant empirical evidence for dispersal syndromes contrasts with the rarity of theoretical predictions about evolution life-history divergence between dispersing and philopatric individuals. We use an evolutionary model to predict optimal differences in age-specific reproductive effort individuals inhabiting same metapopulation. In our model, only young disperse, their lifelong decisions are potentially affected by this initial event. Juvenile survival declines as density adults other...
Abstract Previous models have predicted that when mortality increases with age, older individuals should invest more of their resources in reproduction and produce less dispersive offspring, as both future reproductive value prospect competing own sib decline. Those assumed stable population sizes. We here study for the first time evolution age‐specific effort offspring dispersal rate a metapopulation extinction‐recolonization dynamics juvenile dispersal. Our model explores evolutionary...
Dispersal syndromes describe the patterns of covariation morphological, behavioural, and life-history traits associated with dispersal. Studying dispersal is critical to understanding demographic genetic consequences movements. Among studies describing association dispersal, there anecdotal evidence suggesting that can vary age. Recent theory also suggests dispersive philopatric individuals might have different age-specific reproductive efforts. In a wild population common lizard (Zootoca...
Abstract Despite extensive literature on the pathogenicity and virulence of opportunistic pathogen Escherichia coli , much less is known about its ecological evolutionary dynamics as a commensal in healthy hosts. Based two detailed longitudinal datasets gut microbiota adult individuals followed over months to years France USA, we identified robust trade-off between ability establish new host (colonization) remain (residence). Major E. lineages (phylogroups) exhibited similar fitness but...
Mate choice is a crucial element of many processes in evolutionary biology. Empirical research has shown that mating preference and choosiness often change with age. Understanding the causes patterns age-specific challenging because different mechanisms can give rise to same pattern. Instead focusing on optimal strategy given fitness trade-offs, we approach this question from more general standpoint ask how strength selection changes age at which it expressed. We show modifier depends...
Predicting the adaptation of populations to a changing environment is crucial assess impact human activities on biodiversity. Many theoretical studies have tackled this issue by modeling evolution quantitative traits subject stabilizing selection around an optimum phenotype, whose value shifted continuously through time. In context, population fate results from equilibrium distribution trait, relative moving optimum. Such may vary with shape selection, system reproduction, number loci,...
Abstract Although it seems obvious that antibiotic use promotes resistance, the processes underlying changes in prevalence of MRE European communities are still poorly understood. Information on how within-host bacterial density varies after acquisition a resistant strain and absence selection is key to our ability further understand, model manage resistance community. Empirical studies dynamics following colonization by very scarce. Here, we study healthy travelers colonized with upon their...
