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 ...
Mating behavior in two sympatric species of andean tiger beetles (Cicindelidae).
(2011-10-06)
The tiger beetle genus Pseudoxycheila (Cicindelidae) currently contains 21 species, distributed in mid and high elevations in the Andes from Bolivia to Venezuela and in mountains in Panama and Costa Rica. The center of ...
Variation in the post-copulatory guarding behavior of Neohelice granulata (Brachyura, Grapsoidea, Varunidae) in two different habitats
(John Wiley & Sons Inc, 2014-10)
Crab guarding behaviors are influenced by the biological and physical characteristics that each population experiences in a particular habitat. We studied post-copulatory guarding behavior and the factors affecting it, ...
Mate guarding and territorial aggression vary with breeding synchrony in golden whistlers (Pachycephala pectoralis)
(SPRINGER, 2008-06)
Male paternity assurance behaviour during the
female fertile period has been widely documented amongst
birds. In contrast, how sex-specific behavioural strategies
vary with local breeding synchrony levels remains ...
A hypothesis about the origin of sperm storage in the Eubrachyura, the effects of seminal receptacle structure on mating strategies and the evolution of crab diversity: How did a race to be first become a race to be last?
(Elsevier Gmbh, 2011-10)
The origins and evolution of sperm storage in Brachyura are enigmatic: sperm is either stored in seminal receptacles, accessible via the vulvae on the sixth thoracic sternite, or in spermathecae at the border between the ...
An effective sperm competition avoidance strategy in crabs drives genetic monogamy despite evidence of polyandry
(2016)
For polyandrous species where females have sperm storage structures, males develop several strategies to avoid sperm competition and thus to maximize the number of eggs fertilized. On the other hand, females may receive ...
An effective sperm competition avoidance strategy in crabs drives genetic monogamy despite evidence of polyandry
(Springer, 2016)
For polyandrous species where females have sperm storage structures, males develop several strategies to avoid sperm competition and thus to maximize the number of eggs fertilized. On the other hand, females may receive ...
Mating system of the burrowing crab Neohelice granulata (Brachyura: Varunidae) in two contrasting environments: Effect of burrow architecture
(Springer, 2012-07)
Few studies conducted in crustaceans have demonstrated how habitat features could shape the mating systems. Here, the burrow of Neohelice granulata was considered as a resource used for mating, and its architecture was ...
Is Potimirim potimirim (Crustacea, Decapoda, Atyidae) a protandric hermaphrodite species? Behavioral and morphological aspects of the reproductive system
(2021-07-01)
We evaluated the mating behavior of Potimirim potimirim in the laboratory based on the assumption that this caridean might be hermaphroditic. We also performed histology and scanning electron microscopy analyses of the ...
A parental care-mating dilemma? Potential risks for offspring in the Pholcid spider when egg-carrying females accept mating
(Springer/Plenum Publishers, 2017-03)
Many species face a trade-off between additional mating opportunities and the offspring benefits (viability, quality) provided by parental care. Female Holocnemus pluchei spiders must abandon their egg-sac, which they ...
