Socially cued developmental plasticity in web-building spiders

Abstract: BackgroundSocially cued anticipatory plasticity (SCAP) has been proposed as a widespread mechanism of adaptive life-history shifts in semelparous species with extreme male mating investment. Such mating systems evolved several times independently in spiders and male reproductive success should critically depend on timely maturation and rapid location of a receptive and, ideally, virgin female. We experimentally investigated socially cued anticipatory plasticity in two sympatric, closely related Nephila species… Show more

“…In agreement with two earlier studies on two other spider species (Kasumovic & Andrade, ; Neumann & Schneider, ), male A. bruennichi shortened their subadult stage if they were exposed to the silk of virgin females. The silk contains a specific sex pheromone that attracts males to their web and induces male courtship (Chinta et al., ).…”

“…In agreement with two earlier studies on two other spider species (Kasumovic & Andrade, 2006;Neumann & Schneider, 2016), male A. bruennichi shortened their subadult stage if they were exposed to Data from Southern males (estimates and SE) were log-transformed. In Northern males, we used family lineage as a random factor (26 groups) and in Southern males the collection site (4 groups).…”

“…These factors may favour protandry and amplify the trade-off between developmental time and adult size in males. The importance of a timely maturation was further supported in an experimental study, showing that male N. senegalensis are able to adjust the duration of their subadult instar (i.e., the last developmental stage preceding maturity) to the presence of receptive females by shifting maturation in the order of several days ( Neumann & Schneider, 2016 ). Immature males use female silk (or probably silk-borne pheromones) as a cue to perceive females.…”
