Abstract: Abstract Despite extensive research on mechanisms generating biases in sex ratios, the capacity of natural enemies to shift or further skew operational sex ratios following sex allocation and parental care remains largely unstudied in natural… read more here.

DOI: 10.1002/ece3.3631
Abstract: Abstract Sexual conflict over mating rate is both pervasive and evolutionarily costly. For females, the lifetime reproductive fitness costs that arise through interactions with potential mates will be influenced by the frequency of such interactions,… read more here.

DOI: 10.1016/j.beproc.2017.04.011
Abstract: In polygynous species, sexual selection is mostly driven by male ability to monopolize access to females in oestrous. In ungulates, the operational sex ratio (OSR), i.e. the proportion of males to individuals ready to mate,… read more here.

DOI: 10.1016/j.evolhumbehav.2016.10.013
Abstract: In this paper, we use a combination of evolutionary theory, ethnographic data, written sources, and archaeological evidence to develop a new explanation for the origins of Viking raiding. Our argum ... read more here.
