Animals often need to signal to attract mates and behavioural signalling may impose
substantial energetic and fitness costs to signallers. Consequently, individuals often …

In her influential book “Developmental Plasticity and Evolution,” Mary Jane West-Eberhard
introduced the concept of cross-sexual transfer, where traits expressed in one sex in an …

Parentage analyses via microsatellite markers have revealed multiple paternity within the
broods of polytocous species of mammals, reptiles, amphibians, fishes and invertebrates …

Sexual dimorphism often results from hormonally regulated trait differences between the
sexes. In sex-role-reversed vertebrates, females often have ornaments used in mating …

Endocrine disruptors have devastating impacts on the reproductive physiology of aquatic
organisms. The Gulf pipefish, Syngnathus scovelli, is a sexually dimorphic species, which …

Species lacking distinct secondary sex characteristics, such as differences in size or
morphology, are often thought to experience lower levels of sex‐specific selection in …

In species with sex-specific signalling traits that appear to be ornamental (ie are
conspicuous and with no obvious natural selection benefit), the ornamented sex typically …

Seahorses, pipefishes, and seadragons are fishes from the family Syngnathidae that have
evolved extraordinary traits including male pregnancy, elongated snouts, loss of teeth, and …

Reliably quantifying the strength of visual sexual signals, such as iridescence, has been
challenging across the field of evolutionary biology, but is critically important for studying …
