Sperm Transfer Under Behavioral and Morphological Constraints in the Orb‐Web Spider Genus Argiope
Integrative Zoology, EarlyView.The polygamous mating system of the orb‐web spider genus Argiope provides a model to study the evolution of sperm transfer under morphological and behavioral constraints. This helps us to understand how male and female behavioral and morphological reproductive traits influence sperm transfer.

Integrative Zoology, EarlyView.Sexual cannibalism (SC), where one mating partner consumes the other in the context of mating, is especially prevalent among spiders. However, the evolution of SC in spiders is still not fully understood. We review key hypotheses for SC and explore how female‐initiated SC has driven the evolution of various male counter‐adaptations to mitigate its ...

Animal Conservation, EarlyView.Reproductive success rates are a key parameter determining the recovery potential of ex‐situ managed threatened species, with high rates often being required to produce offspring for wild releases while ensuring ex situ population viability. Here, we quantify reproductive success rates in the Extinct in the Wild sihek (Guam kingfisher) and find ...
