Inter and intraspecific variation in female remating propensity in the cactophilic sibling species Drosophila buzzatii and D. koepferae
(Elsevier, 2013-05)
Post-mating sexual selection by means of sperm competition or cryptic female choice occurs in species in which females remate before exhausting sperm supplied by previous mates. Thus, sperm competition is expected to be ...
Size-Dependent Selective Mechanisms on Males and Females and the Evolution of Sexual Size Dimorphism in Frogs
(Univ Chicago Press, 2014-12-01)
Sexual size dimorphism (SSD) varies in animals from male biased to female biased. The evolution of SSD is potentially influenced by a number of factors, such as territoriality, fecundity, and temporal breeding patterns ...
Lack of phonotactic preferences of female frogs and its consequences for signal evolution
(Elsevier, 2015)
Sexual selection is one of the main evolutionary forces that drive signal evolution. In previous studies, we have found out that males of Pleurodema thaul, a frog with an extensive latitudinal distribution in Chile, emits ...
The Role of Males in Host-Fruit Selection by Females of a Walnut Infesting Tephritid (Diptera) Rhagoletis zoqui
(Springer/plenum Publishers, 2016-01)
Rhagoletis zoqui Bush flies have a mating system in which males guard and defend walnut fruit-hosts from other males and mate, apparently without courtship, with females as they arrive to oviposit. Hypothetically, female ...
The function of female resistance behavior: Intromission by male coercion vs. female cooperation in sepsid flies (Diptera: Sepsidae)

Female tawny-bellied seedeaters do not prefer more colorful males in choice experiments
(Springer Tokyo, 2013-09)
Plumage coloration has long been studied as a sexually selected character. The tawny-bellied seedeater, Sporophila hypoxantha, is a sexually dichromatic species, with adult males the more colorful sex and juvenile males ...
Female Age Determines Remating Behavior in Wild Mexican Fruit Flies: Abraham et al.: Age Effects on Female Remating in A. ludens
(Springer/Plenum Publishers, 2016-05)
Male and female age are important factors that can influence mating and remating behavior. Females can discriminate against or prefer older males, but there have been relatively fewer studies on how female and male age ...
To be or not to be . . . a flower? A test of possible cues influencing hunting site selection in subadult females of the crab spider Epicadus heterogaster (Guerin 1812) (Araneae: Thomisidae)
(Taylor & Francis Ltd, 2012-01-01)
Females of some Thomisidae species are known to use visual and olfactory stimuli to select high quality hunting sites. However, because studies about foraging behavior in this family are concentrated on a few species, the ...
