animal behavior; data collection; females; males; meta-analysis; sex ratio; sexual selection
Abstract:
... The proportion of sexually receptive males in relation to females (operational sex ratio, OSR) is often invoked as an important determinant of the potential for sexual selection. Although the opportunity for sexual selection metric (Is) is frequently used to estimate such potential, recent doubts have been cast about its capacity to disentangle the relative effect of sexual competition from that o ...

Amblypygi; Araneae; animals; burrows; females; field experimentation; habitats; males; observational studies; territoriality; tree and stand measurements; trees; Amazonia
Abstract:
... Animals that select and defend suitable habitats against conspecifics may be favored by maximizing prey encounter rate, gaining protection, or securing matings. However, the identification of habitat selection and territoriality may be hindered in observational studies in sedentary species with low-density populations, such as the whip spider Heterophrynus longicornis. To circumvent such difficult ...

Anisoptera (Odonata); animal behavior; animals; game theory; males; models; ownership; prediction; probability
Abstract:
... Agonistic interactions between males for the ownership of mating territories are common among animal species. There are at least three theoretical models aimed to clarify the rules used by rivals to decide the contest winner: war of attrition model (WOA), sequential assessment model (SAM) and cumulative assessment model (CAM). However, few empirical investigations have simultaneously tested predic ...
