Copulatory behaviour increases sperm viability in female spiders
(Wiley Blackwell Publishing, Inc, 2020-09-20)
One remarkable reproductive feature in animals with internal fertilization is a reduction in sperm viability over time in females. Whether this reduction is driven by male-male competition and/or cryptic female choice is ...
Copulatory behaviour and the process of intromission in Anastrepha ludens (Diptera: Tephritidae)
(Universidad de Costa Rica, 2011)
Consistency of females’ stridulatory behaviour during inter-sexual interactions in spiders
(Wiley Blackwell Publishing, Inc, 2019-08-06)
In a sexual context, it is expected that females base their choice of mate on the behaviours that males perform during courtship, as such behaviours are associated with the male's mate quality. Stridulation is one form of ...
Ontogeny of copulatory behaviour in male Japanese quail classified by their T-maze performance as hatchlings
(Taylor & Francis Ltd, 2008-07)
This study examines the time courses of male mating behaviours using quail that were categorised at 2 d of age as high performance (HP) or low performance (LP) individuals in a T-maze. Individually caged males from each ...
Mating strategies of the endangered insular land crab Johngarthia lagostoma (H. Milne Edwards, 1837)
(2021-01-01)
Hard-shell-mating is the typical way that semi-terrestrial and terrestrial crabs copulate, when females reproduce with a hard carapace during the intermoult period and the couples have a brief or absent pre- and post-copulatory ...
Acoustic signals and behaviour of Ovalipes trimaculatus in the context of reproduction
(Inter-research, 2015-09)
This study focused on the acoustic behaviour of the paddle crab Ovalipes trimaculatus (De Haan, 1833) in relation to its reproductive status and behaviour. Paired males and females (demonstrating pre-copulatory behaviour) ...
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. ...
Selection for contrasting adrenocortical responsiveness in Japanese quail (Coturnix japonica) influences sexual behaviour in males
(Elsevier Science, 2003-09-26)
Selection of Japanese quail for a reduced (low stress, LS) rather than exaggerated (high stress, HS) adrenocortical response to brief restraint is associated with a non-specific reduction in stress responsiveness, decreased ...
