Cannibalismus sexualis

Cannibalismus sexualis est cannibalismus coniugis a femina ante, per, vel post copulationem effectus.Polis et Farley 1979. Quae plerumque est res cuius proprietas speciebus plurimorum arachnidorum ordinum, ac nonnullis ordinibus insectorum est.Buskirk, Frohlich, et Ross 1984/ Inter coniecturas ad evolutionem cannibalismi sexualis explanandam propositas sunt hypothesis pabulandi adaptivi,Anglice: "adaptive foraging hypothesis" (Blamires 2011). hypothesis nimii hostilis,Anglice: "aggressive spillover hypothesis" (Arnqvist 1992). et hypothesis identitatis falsae.Anglice: "mistaken identity hypothesis" (Gould 1984). Qui mores sese evolvisse putantur e pugna sexuali, quae fit cum genitales marium et feminarum usus variarent.Chapman et al. 2003. In multis speciebus quae cannibalismum sexualem exhibent, femina marem detectum consumit. Feminae specierum cannibalisticarum plerumque hostiles sunt, coire invitae; ergo multi mares harum specierum mores adaptivos evolverunt ut aggressionem feminae evitent.Zhang, Kuntner, et Li 2011.Fromhage et Schneider 2004.

Cannibalismus sexualis plerumque videtur inter insecta, arachnida,Polis 1981. et amphipoda.Polis 1981. Sunt etiam indicia cannibalismi sexualis inter gastropoda et copepoda.Bilde et al. 2006. Cannibalismus sexualis pervulgatus est inter species quibus est prominens dimorphismus magnitudinis sexualis; extremus quidem talis dimorphismus evolutionem cannibalismi sexualis in araneis propellere videtur.Wilder et Rypstra 2008.
