Abstract:
... Evolutionary rescue (ER) occurs when adaptation prevents extinction under lethal selection. However, the lack of empirical studies addressing the possible factors enabling ER limits our understanding of the current biodiversity crisis in the context of global change. Here we addressed the roles of environmental deterioration rate and dispersal of metapopulations on the dynamics of ER in the freshw ...

Microcystins are highly toxic metabolites derived from some cyanobacteria species that exert its main effect in the liver through the inhibition of protein phosphatase (PP1 and PP2A). However, other damages in fish ...
