Data from: Genotype-dependent responses to levels of sibling competition over maternal resources in mice

Reinmar Hager, James M. Cheverud & Jason B. Wolf
Research on phenotypic plasticity has often focused on how a given genotype responds to changing physical environments. However, for many species the social environment plays an equally important role due to competition for resources. During early development, the level of competition for limited resources will often depend critically on the number of siblings. Therefore, competition among siblings should drive the evolution of genes that allow flexible responses to realized levels of competition and maternal resource...

Data from: Persistence of an extreme male-biased adult sex ratio in a natural population of polyandrous bird

András Kosztolányi, Zoltan Barta, Clemens Küpper & Tamás Székely
In a number of insects, fishes and birds the conventional sex roles are reversed: males are the main care provider whereas females focus on matings. The reversal of typical sex roles is an evolutionary puzzle, because it challenges the foundations of sex roles, sexual selection and parental investment theory. Recent theoretical models predict that biased parental care may be a response to biased adult sex ratios (ASRs). However, estimating ASR is challenging in natural populations,...
