WebPhenotypic and genetic divergence are shaped by the homogenizing effects of gene flow and the differentiating processes of genetic drift and local adaptation. Herein, we … 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 …

Experimental evidence that phenotypic divergence in predators drives …

We 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. Body size was measured as snout-vent length (SVL) of 307 … See more To characterize patterns of genetic divergence, we developed nine microsatellite loci for E. anthonyi at the EG Cornell Facility as described in Páez-Vacas and Oleas (2024). … See more WebSep 7, 2024 · Phenotypic variation, then, is the variability in phenotypes that exists in a population. For example, people come in all shapes and sizes: height, weight, and body shape are phenotypes that vary. over the counter for ulcer

Genetic structure is correlated with phenotypic divergence rather …

WebAug 18, 2015 · Introduction. Speciation commonly proceeds through genetic divergence between populations that ultimately become reproductively isolated from each other due to intrinsic and/or extrinsic breeding barriers ( Orr and Turelli 2001; Coyne and Orr 2004; Smadja and Butlin 2011; Nosil and Feder 2012).Phenotypic trait divergence usually … WebIn contrast, divergence between replicate populations within each habitat was approximately pro-portional to the level of genetic variance, a result consistent with theoretical predictions for neutral phenotypic divergence.Divergence between the two species was also primarily along major eigenvectors of G. Our results therefore suggest that ... WebWe find that divergence of ebony does indeed contribute to the pigmentation divergence between species, with effects on both the overall body color as well as a difference in pigmentation along the dorsal abdominal midline. over the counter for yeast infection walmart
