Morphology of seminal receptacle of the harvested golden crab Chaceon chilensis and its implication in the fertilization process
(2017)
The external and internal architecture of crab seminal receptacles are closely associated with mating behavior, sperm transfer, and storage patterns, and ultimately reproductive success. Therefore, describing their anatomy ...
Mating plugs and sexual cannibalism : variations between populations of the neotropical spider Leucauge mariana
(Universidad de los AndesMaestría en Ciencias BiológicasFacultad de CienciasDepartamento de Ciencias Biológicas, 2017)
"Geographic distribution and its interconnected biotic and abiotic factors, may favor variation in the expression of sexual displays. In Leucauge orb web spiders females participate in mating plugs formation and use them ...
Sexual selection in neotropical spiders: Examples from selected groups
(Springer, 2017)
Spiders have long been noted as classic examples of sexual behavior among arachnids, including extreme sexual dimorphism in some groups, and behavioral adaptations to diverse mating patterns. In recent decades, studies on ...
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 ...

Male performance and associated costs in successive sexual encounters in a polygynous web wolf spider
(Springer Heidelberg, 2019-10-14)
Polygynous males increase their reproductive success by fertilizing as many females as possible. However, this strategy can lead to costs for the males. This study focused on an atypical wolf spider that lives in webs, ...
Genital Anatomy and Copulatory Interactions in the Broad Snouted Caiman (Caiman latirostris)
(Wiley-liss, div John Wiley & Sons Inc., 2021-07)
The broad snouted caiman is a crocodylian native to South America that is subject to extensive conservation management in both wild and farming environments. Although reproductive behaviors like egg laying and clutch care ...
Microsatellite evidence for sperm storage and multiple paternity in the marine gastropod Crepidula coquimbensis
(ELSEVIER SCIENCE BV, 2011)
In gregarious species with copulation and internal fertilization, male-male competition and female cryptic choice may affect reproductive success of both sexes. We carried out a molecular analysis to study paternity and ...
