This study tests how divergent natural selection promotes genomic differentiation during ecological speciation. Specifically, we use adaptive ecological divergence (here, population divergence in host plant use and preference) as a proxy for selection strength and evaluate the correlation between levels of adaptive and genetic differentiation across pairwise population comparisons. Positive cor...

1. Species reintroductions often aim to establish populations of threatened taxa over the long-term. However, climate change may jeopardize reintroduction efforts by altering conditions a recipient site beyond tolerances focal species. To aid selection sites that will retain their suitability under change, species distribution models (SDMs) have been proposed as method locating areas with great...

Under the effects of strong genetic drift, it is highly probable to observe gene fixation or loss in a population, shown by divergent probability density functions, or infinite adaptive peaks on a landscape. It is then interesting to ask what such infinite peaks imply, with or without combining other biological factors (e.g. mutation and selection). We study the stochastic escape time from the ...
