WebMar 2, 2016 · Precisely predicting evolutionary responses to harvest is difficult because changes in a population's vital rates can affect density dependence, particularly at juvenile life stages, as well as biotic interactions with other species (Polacheck et al. 2004; Howell et al. 2013; Kuparinen et al. 2014a ). WebAug 26, 2024 · Human harvest can induce selection on life history and morphological traits, leading to ecological and evolutionary responses.

We subjected six populations of silverside fish (Menidia menidia) to three forms of size-selective fishing for five generations, thereby generating twofold differences among populations in mean weight and yield (biomass) at … Both theory and empirical studies suggest that harvest-induced evolution could lead to reduced body size and earlier maturation. These evolutionary changes are unlikely to be reversed rapidly when harvesting ceases, because artificial selective pressures are often much stronger than natural selection [14]. … See more The study of harvest-induced evolution only began to attract substantial scientific attention in the 1990s, even though it had been recognized for … See more Despite the debate surrounding the paucity of rigorous investigations linking observed phenotypic trends to changes in the genetic … See more Managers should consider ‘evolutionary sustainable’ harvesting strategies to prevent the long-term negative impacts of harvest-induced evolution.
