A potential mechanism for cryptic female choice in a flour beetle

Cryptic female choice of mates in flour beetles (Coleoptera: Tenebrionidae)

Sexual selection drives the evolution of diverse traits that provide an advantage in reproduction. In polyandrous species the traditional premating processes of male-male competition and female choice have as counterparts sperm competition and cryptic female choice (CFC) occurring during and after mating; these processes determine paternity shares of multiple males mated to the same female. I c...

Cryptic Female Choice

Evidence of female cryptic choice in crayfish.

To test whether male body size affects female reproductive investment in the polygamous crayfish Procambarus clarkii, we described mating behaviour of virgin females paired with either small or large males, and analysed the number, size and weight of both eggs and juveniles sired by either types of male. Along with confirming the overt selection by females of larger mates, we found that the siz...

passivity in waiting for godot and endgame: a psychoanalytic reading

this study intends to investigate samuel beckett’s waiting for godot and endgame under the lacanian psychoanalysis. it begins by explaining the most important concepts of lacanian psychoanalysis. the beckettian characters are studied regarding their state of unconscious, and not the state of consciousness as is common in most beckett studies. according to lacan, language plays the sole role in ...
