Are we underestimating the genetic variances of dimorphic traits? 

Wolak, Mathew E.; Roff, Derek A.; Fairbairn, Daphne J. (2022-09-16)
Populations often contain discrete classes or morphs (e.g., sexual dimorphisms, wing dimorphisms, trophic dimorphisms) characterized by distinct patterns of trait expression. In quantitative genetic analyses, the different ...

Evolution of life histories along elevational gradients: Trade-off between parental care and fecundity 

Badyaev, Alexander V.; Ghalambor, Cameron K. (2020-04-20)
Life history responses to environmental conditions include a combination of fecundity-survival schedules and behavioral strategies that yield the highest fitness in a given environment. In this study, we examined the pattern ...
