The signalling function of melanin‐based colouration is debated. Sexual selection theory
states that ornaments should be costly to produce, maintain, wear or display to signal quality …

Mate choice in most organisms is not random, but determined by a suite of interacting traits
and environmental factors. While the selective pressures underlying differences in mate …

Female preferences for specific male phenotypes have been documented across a wide
range of animal taxa, including numerous species where males contribute only gametes to …

In this study, we investigated two potentially important intersexual postcopulatory gametic
interactions in a population of chinook salmon (Oncorhynchus tshawytscha):(i) the effect of …

Small or declining populations are at increased risk of extinction because of stochasticity
and Allee effects (Lande 1998, Courchamp et al. 1999, Stephens and Sutherland 1999 …

Sperm cryopreservation is routinely used in reproductive medicine, livestock production and
wildlife management. Its effect on offspring performance is often assumed to be negligible …

In some fishes, water chemistry or temperature affects sex determination or creates sex‐
specific selection pressures. The resulting population sex ratios are hard to predict from …

Major histocompatibility complex (MHC)-dependent mating preferences have been
observed across vertebrate taxa and these preferences are expected to promote offspring …

Salmonid fish have become important models in evolution and ecology, but possible effects
of embryo or larval sex are mostly ignored, probably because morphological gonad …

Recent studies found fish egg‐specific bacterial communities that changed over the course
of embryogenesis, suggesting an interaction between the developing host and its …
