TL;DR: The demographic and genetic processes at play in small populations, be they stochastic or deterministic, are reviewed and the theoretical outcomes of these different processes with respect to individual fitness, population growth rate, and establishment probability are discussed.

TL;DR: Spatial heterogeneity and presence of density‐ and frequency‐dependent feedbacks in the environment could allow for the emergence of such alternative strategies in this population and the maintenance of colour variation in females.

TL;DR: The findings are consistent with a scenario of recurrent introgressive hybridization but at a very low level and through secondary contact following initial divergence in allopatry, and mirrors previous findings on introgression between the two host plants.

TL;DR: The population structure in Europe of two Microbotryum species causing anther smut disease on the plants Silene latifolia and Silene dioica is studied to indicate that migration patterns caused by climate change can be expected to include pathogen invasions that follow the redistribution of their host species at continental scales, but also that the recolonization by pathogens is not simply a mirror of their hosts, even for obligate biotrophs.

TL;DR: This study is believed to be the first empirical documentation of critical patch size induced by an Allee effect, and confirmed here using a mechanistic model developed for the gypsy moth system.
