Sexually antagonistic selection, sexual dimorphism, and the resolution of intralocus sexual conflict

RM Cox, R Calsbeek - The American Naturalist, 2009‏ - journals.uchicago.edu
Males and females share most of their genomes and express many of the same traits, yet the
sexes often have markedly different selective optima for these shared traits. This sexually …

Experimental Evidence for Aposematism in the Dendrobatid Poison Frog Oophaga pumilio

RA Saporito, R Zuercher, M Roberts, KG Gerow… - Copeia, 2007‏ - meridian.allenpress.com

Intraspecific color diversity and camouflage associated with ontogeny in an insular land crab

MCA João, RC Duarte, AS Freire… - Behavioral Ecology and …, 2023‏ - Springer
Many species exhibit high intraspecific color variation between sexes or ontogenetic phases

Sexual dimorphism and intra-populational colour pattern variation in the aposematic frog Dendrobates tinctorius

B Rojas, JA Endler - Evolutionary Ecology, 2013‏ - Springer
Despite the predicted purifying role of stabilising selection against variation in warning
signals, many aposematic species exhibit high variation in their colour patterns. The …
