Sexual selection driving diversification in jumping spiders [PDF]

open access: yesProceedings of the National Academy of Sciences, 2002
Theory predicts that speciation rates should be accelerated in organisms undergoing sexual selection. In systems involving female choice, sexual selection acts directly on traits that may be important in prezygotic reproductive isolation, potentially fostering rapid divergence of such traits among allopatric populations. Despite the appeal

Matching habitat choice could be brightness‐based instead of hue‐based in green‐brown polymorphic grasshoppers

open access: yesOikos, EarlyView.
Some prey species have evolved background matching, that is they resemble their surrounding environment in terms of colour and/or brightness. When prey populations inhabit patchy environments, they may even have evolved specialised phenotypes: each phenotype matching a specific subset of patches.
