Reproductive behaviour of three species of freshwater crabs of the family Trichodactylidae (Crustacea: Decapoda) including forced copulation by males
(Taylor & Francis Ltd, 2015-03)
This report includes a detailed description of the reproductive behaviour of the freshwater crab Zilchiopsis collastinensis in the family Trichodactylidae and some observations on two other genera. It presents observations ...
Female monopolization and paternity assurance in South American crickets (Orthoptera, Grylloidea): mating plugs, extra claspers and forced copulation
(USP, 2007-01-01)
Este trabalho descreve os primeiros três casos em que grilos machos monopolizam suas fêmeas através de plugues de acasalamento. A origem dessas estruturas varia entre os casos (i.e., não há homologia entre as mesmas). A ...

Life History and Mating Behavior of Rhagoletis solanophaga (Diptera: Tephritidae), a Non-Diapausing Species with Highly Variable Mating Duration
(Springer/plenum Publishers, 2016-11)
As an initial contribution to understanding the adaptive value of behavioral and life-history strategies, the life cycle and mating behavior of an unstudied species of tephritid fruit fly in the genus Rhagoletis are ...
Copulation behaviour of Glossina pallidipes (Diptera: Muscidae) outside and inside the female, with a discussion of genitalic evolution
(Bulletin of Entomological Research (2007) 97, 1–18, 2007-04-26)
If species-specific male genitalia are courtship devices under sexual selection by cryptic female choice, then species-specific aspects of the morphology and behaviour of male genitalia should often function to stimulate ...

Patterns of sperm transfer behavior in a pholcid spider with two distinct copulatory phases
(Springer New York LLC, 2018-11)
Sexual selection is the responsible force for the evolution and maintenance of genital diversity and function. This is the case for example, of genital movements performed by males during mating and copulation duration. ...

Fertility of male adult rats submitted to forced swimming stress
(Associação Brasileira de Divulgação Científica (ABRADIC), 2003-05-01)
We investigated whether stress interferes with fertility during adulthood. Male Wistar rats (weighing 220 g in the beginning of the experiment) were forced to swim for 3 min in water at 32ºC daily for 15 days. Stress was ...
