A combinatorial view on speciation and adaptive radiation

DA Marques, JI Meier, O Seehausen - Trends in ecology & evolution, 2019 - cell.com
Speciation is often thought of as a slow process due to the waiting times for mutations that
cause incompatibilities, and permit ecological differentiation or assortative mating. Cases of …

Genetic load has potential in large populations but is realized in small inbred populations

S Mathur, JA DeWoody - Evolutionary Applications, 2021 - Wiley Online Library
Populations with higher genetic diversity and larger effective sizes have greater evolutionary
capacity (ie, adaptive potential) to respond to ecological stressors. We are interested in how …

Genetic variation for adaptive traits is associated with polymorphic inversions in Littorina saxatilis
