Fishing selection and phenotypic evolution
Did you know?
WebExploitation of fish populations can induce evolutionary responses in life histories. For example, fisheries targeting large individuals are expected to select for early maturation at smaller sizes, leading to reduced fecundity and thus also reduced fisheries yield. These predicted phenotypic shifts have been observed in several fish stocks, but … WebApr 29, 2024 · A fishing–warming synergy only became apparent at the individual scale where harvest resulted in the 50% reduction of thermal growth reaction norm diversity. This phenotypic change was primarily caused by the loss of larger individuals that showed a strong positive response to temperature change after the onset of size-selective harvesting.
WebEctotherms such as insects are animals whose body temperature largely depends on ambient temperature and temperature variations provide a selection pressure affecting the geographical distribution of these species. However, over the course of evolution, some insect species managed to colonize environments characterized by various temperature ...
WebJun 1, 2000 · The cause of these phenotypic changes is often not understood, and genetic change arising from the selective effects of fishing may be a contributory factor. Selection generated by fishing gear is strong in heavily exploited fish stocks, and the spatial … WebFeb 22, 2024 · Anticipating and preparing for future evolutionary changes within harvested populations whether by fishing or hunting is critical for sustainable natural resource management and successful conservation of ecosystems (1–6).Harvest-induced evolution is a concern for both commercial and recreational fisheries, and harvest from …
