Despite 250 years of work in systematics, the majority of species remains to be identified.
Rising extinction rates and the need for increased biological monitoring lend urgency to this …

Avec presque 40 000 espèces, les araignées constituent un modèle important pour l'étude
de la vie sociale, des systèmes d'accouplement et du dimorphisme sexuel. Cependant, la …

Spiders use pheromones for sexual communication, as do other animals such as insects.
Nevertheless, knowledge about their chemical structure, function, and biosynthesis is only …

Mate searching is a risky behavior that decreases survival by increasing predation risk and
the risk of energy depletion. However, few studies have quantified actual mortality during …

In species where virgin females have higher reproductive value to males than nonvirgin
females, selection will favour males that can discriminate female reproductive status …

Although females rarely experience strong mate limitation, delays or lifelong problems of
mate acquisition are detrimental to female fitness. In systems where males search for …

Spiders are well known for using chemical, vibratory, tactile, and visual signals within mating
contexts. All spiders produce silk, and even in non-web building spiders, silk is intimately …

Bateman's principle predicts the intensity of sexual selection depends on rates of increase of
fecundity with mating success for each sex (Bateman slopes). The sex with the steeper …

Theory predicts that interplay between sexual and natural selection shapes phenotypic
distributions over evolutionary time [1–3]. We show that this also significantly affects …

Strong male mate preferences have been documented in species with otherwise
conventional sex roles in the laboratory, and across taxa, male preferences generally focus …
