Morphological and behavioural traits place Filistatidae basally within Araneomorphae, although some features, such as their continuing to moult after reaching adulthood, are reminiscent of mygalomorph spiders. This paper ...

The evolutionary effects of crowding on male courtship behavior were studied using wild and mass-reared medflies. Mass-reared strains had been raised under highly crowded conditions in mass-rearing facilities for ...

Courtship and breeding behaviour of anurans is species-specific and defined by vocalisation, although breeding activities are still understudied for many species. Here, we describe the courtship behaviour and unpublished ...

Reproduction involves communication. Males usually evolve elaborate displays that may declare their qualities and attract females to mate, using signals from different modalities. Females may use cues encoded in courtship ...

Postcopulatory sexual selection has shaped the ornaments used during copulatory courtship. However, we know relatively little about whether these courtship ornaments are costly to produce or whether they provide indirect ...

Complex courtships have been described for neotropical frogs, but detailed quantifications of calls emitted during this behavior are still rare. Herein, we describe the courtship call of Bokermannohyla ibitiguara, a gladiator ...
