Speciation by Natural and Sexual Selection: Models and Experiments
TLDR
It is shown that the geographical context of speciation can be viewed as a form of assortative mating and this provides a framework for interpreting results from laboratory experiments, which are found to agree generally with theoretical predictions about conditions that are favorable to the evolution of prezygotic isolation. Expand
Live Where You Thrive: Joint Evolution of Habitat Choice and Local Adaptation Facilitates Specialization and Promotes Diversity
TLDR
Unless trapped by maladaptive genetic constraints, joint evolution of local adaptation and habitat choice in the models analyzed here always leads to specialists, independent of life cycle, density regulation, and trade‐off strength, thus raising the bar for evolutionarily sound explanations of generalism. Expand
Aggressiveness and its role in the adaptation of plant pathogens
TLDR
Adaptations of pathogen aggressiveness components to host and environment are analysed, showing that selection for aggressiveness in pathogen populations can be mediated by climatic parameters and selection for quantitative traits can influence pathogen evolution in agricultural pathosystems and can result in differential adaptation to host cultivars, sometimes leading to erosion of quantitative resistance. Expand
Linking dendritic network structures to population demogenetics: The downside of connectivity
TLDR
The main results show that connectivity in dendritic networks can promote local extinction and genetic isolation by distance at low dispersal and diminish the size of the metapopulation at high dispersal. Expand
Anthropogenically induced adaptation to invade (AIAI): contemporary adaptation to human-altered habitats within the native range can promote invasions
TLDR
It is proposed that recent adaptation within the native range, in particular adaptations to human‐altered habitat, could also contribute to the evolution of invasive populations. Expand
The chestnut blight fungus world tour: successive introduction events from diverse origins in an invasive plant fungal pathogen
TLDR
This study confirmed the importance of multiple introductions, but questioned the role of genetic admixture in the success of introduction of a fungal plant pathogen. Expand
Is There a Genetic Paradox of Biological Invasion
TLDR
This work proposes research directions into remaining paradoxical aspects of introduced populations, as seen in introduced populations with low diversity in neutral markers that maintain high genetic variation in ecologically relevant traits. Expand
Implications of habitat choice for protected polymorphisms
TLDR
Analysis of the third class of models introduced here suggests that the joint evolution of matching habitat choice and local- adaptation polymorphism is easier than was previously understood. Expand
Long-Distance Wind-Dispersal of Spores in a Fungal Plant Pathogen: Estimation of Anisotropic Dispersal Kernels from an Extensive Field Experiment
TLDR
Two field experiments designed to measure disease gradients caused by sexually- and asexually-produced spores of the wind-dispersed banana plant fungus Mycosphaerella fijiensis measure the dispersal kernel and discuss the validity of the results as well as their implications in terms of disease diffusion and management strategy. Expand
Contrasting introduction scenarios among continents in the worldwide invasion of the banana fungal pathogen Mycosphaerella fijiensis
TLDR
An original and unprecedented global scenario of invasion for this recently emerging disease caused by a wind‐dispersed pathogen is revealed. Expand
