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 … http://mnmuskie.org/wp-content/uploads/2013/04/size-issues659_002.pdf
WebSo the third kind of selection is diversifying selection. And there's a phenotypic distribution. But this time selection is against individuals toward the mean. And it begins, then, in the next generation, to split the part the population apart a little bit in this phenotypic distribution. So positive selection is selection that spreads an allele.

Parallel phenotypic changes thus masked highly divergent 5 genomic responses to selection, illustrating how contingent rapid adaptation can be in the face of strong human-induced selection. One Sentence Summary: Fish harvest drive rapid evolution in growth rates through inconsistent genomic shifts. 10 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 ...
