Reproductive interference between two sibling species of gift-giving spiders
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTDLONDON, 2012)
We investigated the possibility of reproductive interference between two sibling spider species, Paratrechalea azul and Paratrechalea ornata, which occur syntopically and reproduce synchronously. Males of both species offer ...
Worthless and nutritive nuptial 1 gifts: mating duration, sperm stored and potential female decisions in spiders
(Public Library Of Science, 2015-06)
In nuptial gift-giving species females sometimes select their potential mates based on the presence and size of the gift. But in some species, such as the Neotropical polyandrous spider Paratrechalea ornate male gifts vary ...
