DOI: 10.1016/j.jcz.2016.12.002
Abstract: Abstract Comparisons between populations that differ in resource availability and in environmental variables affecting the intensity of male–male competition allow insights into the mechanisms shaping reproductive allocation. Here, we studied inter-population variation in male investments… read more here.
