Experimental modifications imply a stimulatory function for male tsetse fly genitalia, supporting cryptic female choice theory
(THE AUTHORS. J. EVOL. BIOL. 22 (2009) 151 6-1525 JOURNAL COMPILATION, 2009)
One of the most sweeping of all patterns in morphological evolution is that animal genitalia tend to diverge more rapidly than do other structures. Abundant indirect evidence supports the cryptic female choice (CFC) ...
Artificial insemination unveils a first-male fertilization advantage in the guppy
(Academic Press Ltd - Elsevier Science Ltd, 2017-09)
Several factors are involved in determining the outcome of sperm competition. In addition to sperm number, sperm quality and male phenotype, insemination order is often associated with skewed paternity share. Patterns of ...
Female genital morphology and mating behavior of Orchestina (Arachnida: Araneae: Oonopidae)
(Elsevier Gmbh, 2010-03)
The unusual reproductive biology of many spider species makes them compelling targets for evolutionary investigations. Mating behavior studies combined with genital morphological investigations help to understand complex ...
Sexual Selection and the Evolution of Male Reproductive Traits in Benthic Octopuses
(Frontiers Media S.A., 2019-11)
Competition between same-sex organisms, or intra-sexual selection, can occur before and after mating, and include processes such as sperm competition and cryptic female choice. One of the consequences of intra-sexual ...
Cryptic coloration and choice of escape microhabitats by grasshoppers (Orthoptera: Acrididae)

Worthless and nutritive nuptial 1 gifts: mating duration, sperm stored and potential female decisions in spiders
(Public Library Of Science, 2015-06)
In nuptial gift-giving species females sometimes select their potential mates based on the presence and size of the gift. But in some species, such as the Neotropical polyandrous spider Paratrechalea ornate male gifts vary ...
Female mediation of competitive fertilization success in Drosophila melanogaster
(National Academy Of Sciences, 2013-06)
How females store and use sperm after remating can generate postcopulatory sexual selection on male ejaculate traits. Variation in ejaculate performance traits generally is thought to be intrinsic to males but is likely ...
Expulsion and consumption of male ejaculates by promiscous female euxesta eluta and euxesta mazorca (Diptera: Ulidiidae)
(Taylor & Francis Ltd, 2018-06)
While expulsion of male ejaculates by the females after copulation has been reported for various animal groups, expulsion followed by consumption of the expelled ejaculate is a rare behaviour outside spermatophylax-producing ...
Hairy kisses: tactile cheliceral courtship affects female mating decisions in Leucauge mariana (Araneae, Tetragnathidae)
(2015)
Sexual selection is thought to be an important force driving the evolution of sexually dimorphic morphology and behavior, but direct experimental tests of the functions of species-specific details of morphology are rare ...
