DOI: 10.1002/ece3.10057
Abstract: Abstract Sexual selection is a key evolutionary force but varies widely between populations. Two key factors that influence sexual selection are the extent to which females copulate with multiple males (polyandry) and variation in the… read more here.

Abstract: Abstract Sexual size dimorphism results when female and male body size is influenced differently by natural and sexual selection. Typically, in polygynous species larger male body size is thought to be favored in competition for… read more here.

DOI: 10.1002/ece3.8567
Abstract: Abstract Sexually selected traits may also be subject to non‐sexual selection. If optimal trait values depend on environmental conditions, then “narrow sense” (i.e., non‐sexual) natural selection can lead to local adaptation, with fitness in a… read more here.

Abstract: Abstract Avian feathers need to be replaced periodically to fulfill their functions, with natural, social, and sexual selection presumably driving the evolution of molting strategies. In temperate birds, a common pattern is to molt feathers… read more here.

Sex in murky waters: algal-induced turbidity increases sexual selection in pipefish

DOI: 10.1007/s00265-017-2310-8
Abstract: Algal-induced turbidity has been shown to alter several important aspects of reproduction and sexual selection. However, while turbidity has been shown to negatively affect reproduction and sexually selected traits in some species, it may instead… read more here.

DOI: 10.1007/s11538-017-0353-7
Abstract: The males of the species of frogs Engystomops pustulosus produce simple and complex calls to lure females, as a way of intersexual selection. Complex calls lead males to a greater reproductive success than what simple… read more here.

DOI: 10.1016/j.cois.2017.09.010
Abstract: Insects utilise chemical cues for a range of different purposes and the complexity and degree of specificity of these signals is arguably unparalleled in the animal kingdom. Chemical signals are particularly important for insect reproduction… read more here.

Evolution: Natural selection, sexual selection, and the jaws of death

DOI: 10.1016/j.cub.2021.07.077
Abstract: Traits that increase reproductive success in males can have negative fitness consequences in females. A new study shows that natural selection by a predator that targets males with larger secondary sexual traits drives an evolutionary… read more here.
