WebLarge changes are taking place in yield-determining traits of commercially exploited fish, including traits such as size-at-age and age-at-maturation. The cause of these … 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 11, 2024 · An available high-quality reference genome sequence is key to elucidating the species’ origin and evolutionary history as well as the genetic basis underlying its phenotypic diversity, which can further accelerate future breeding processes 12. Despite the economic importance and evolutionary significance of cultivated chrysanthemum, its ... WebApr 12, 2024 · With a rich foundation of studies on selection and phenotypic divergence, we reference the poison frog genus Oophaga to model signal evolution. Multifarious selection on aposematic traits created the topology of our model's fitness landscape by approximating different scenarios found in natural populations. Combined, the model … birthday ideas for baby boy
Selective fishing and phenotypic evolution: Past, present …
WebSelectivity of fishing is traditionally described in terms of body length. Clearly, this is not necessarily the trait determining whether a fish is captured or not, but because of being most easily measurable and strongly correlated with the other traits affecting capture probability (such as girth or mouth size), it has become established as the primary … WebSUMMARY. EVS 518 Sustainable Natural Resource Management Law et al. 2000 (Fishing, Selection, and Phenotypic Evolution) 01/30/ Context. There is an increasing need for food for humans, notably in the field of fisheries, and this demand is being driven by causes such as the expansion in the human population and the accelerating speed of technological … WebJan 19, 2024 · Commercial and recreational harvests create selection pressures for fitness-related phenotypic traits that are partly under genetic control. Consequently, harvesting can drive evolution in targeted traits. However, the quantification of harvest-induced evolutionary life history and phenotypic change … danny gokey remarried
