Sexual selection and life history are firmly established disciplines in evolutionary biology,
and associated theory and research are focused on determining the ultimate and proximate …

Background That crime is concentrated at a few places is well established by over 44
studies. This is true whether one examines addresses or street segments. Additionally, crime …

Sexual size dimorphism may evolve as a result of both natural and sexual selection. In
polygynous mammals, the main factor resulting in the evolution of large body size in males …

Is the cost of reproduction different between males and females? On the one hand, males
typically compete intensely for mates, thus sexual selection theory predicts higher cost of …

Reproductive effort in female ungulates originates from gestation and lactation and has
been studied extensively; however, no comparable studies of reproductive effort in males …

Rhythmic stability (nonrandom temporal structure) is required for many neural and
physiological functions, whereas rhythmic irregularities can indicate genetic or …

Background Models of honest advertisement predict that sexually selected calls should
signal male quality. In most vertebrates, high quality males have larger body sizes that …

Male African elephants experience intense intrasexual selection in gaining access to
oestrous females, who represent a very scarce and highly mobile resource. An unusual …

Across vertebrates, high social status affords preferential access to resources, and is
expected to correlate positively with health and longevity. Increasing evidence, however …

Survival and reproduction are key features in the evolution of life–history strategies. In this
study, we use capture–mark–resighting and multi–state models to examine survival …
