Phenotypic divergence
WebApr 19, 2010 · Our results support the hypothesis that phenotypic divergence in swamps sparrows is the result of genetic differentiation, and demonstrate that adaptive traits have evolved more rapidly than ... WebJun 16, 2024 · The post hoc tests indicated that phenotypic divergence may be largest between CKD/T2DM patients compared to controls and much less between CKD patients compared to controls. While this may represent the additive burden of risk-increasing co-morbidities, this may also be driven by the age difference between cases and controls in …

Depending on their diet, spadefoot toad tadpoles in the genus Spea develop into either an omnivore ... WebDec 8, 2024 · We measured phenotypic divergence by using field playback experiments to measure vocal behavioral discrimination between sister pairs on either side of the Marañón Gap, in concert with plumage and morphological measurements from museum specimens. To test for a phylogenetic component to rates of phenotypic evolution, we asked whether …
WebAug 12, 2024 · A three-year reciprocal transplant illustrates that, beyond strong maternal effects and phenotypic plasticity, genetically driven divergence in seedling growth and leaf traits was detected both between seedlings originating from different regions, and between seedlings from different microhabitats. WebApr 10, 2024 · extended phenotypic datasets is needed to more rigorously explain the distinct causes underlying the patterns displayed by these lineages. The analysis here represent only a starting point from which to draw deeper links between the evolution of phenotypic variation across species bounds and the ecological strategies employed by …
WebGenetic divergence can occur without geographic separation, through Disruptive selection.This occurs when individuals in a population with both high and low phenotypic extremes are fitter than the intermediate phenotype. These individuals occupy two different niches, within each niche there is Gaussian trait distribution. If the genetic variation … WebMay 22, 2024 · Phenotypic distinctness hindered detection of their relationships with their close relatives and resulted in incorrect classification in the past. This rapid phenotypic divergence happened in several genera. The following are the five most prominent examples ( figure 2 ). Figure 2. Rapidly diverging wing patterns in close relatives.
WebJul 31, 2024 · Ecomorphological divergence can occur via genetic mechanisms or via phenotypic plasticity. While the former may facilitate adaptation over many generations, the latter permits populations to respond to variation in environmental conditions within a generation by remodeling their morphology.
WebUsing this approach, we identified modules of coexpressed genes involved in phenotypic divergence and their key drivers, and further identified a module part specifically rewired in the backcross progeny. Functional analysis of transcriptomic data can significantly contribute to the understanding of the mechanisms underlying ecological speciation. medication used panic attacksWe sampled 535 individuals from 35 localities of E. anthonyi from 2012 to 2014 encompassing the species’ range in Ecuador, which constitutes approximately half of its entire range … See more We downloaded environmental data from online GIS databases for 25 continuous variables hypothesized to affect E. anthonyi genetic and … See more To assess phenotypic divergence, we focused on size and color from 19 sites.
