Time till death affects spider mobility and web-building behavior during web construction in an orb-web spider
It is well known that age influences organism mobility. This was demonstrated in vertebrates (such as mammals and birds) but has been less studied in invertebrates with the exception of Drosophila and the nematode Caenorhabditis elegans. Here we studied the influence of age on the mobility of the orb-weaving spider Zygiella x-notata during web construction. The orb-web is a good model because i...

متن کاملFemale genital mutilation and monandry in an orb-web spider.
Monandry, in which a female has only one mating partner during the reproductive period, is established when a female spontaneously refrains from re-mating, or when a partner male interferes with the attempts of a female to mate again. In the latter case, however, females often have countermeasures against males, which may explain why polyandry is ubiquitous. Here, I demonstrate that the genital...
متن کاملMales under attack: sexual cannibalism and its consequences for male morphology and behaviour in an orb-weaving spider
During their quest to maximize fertilization success, males may be under sexual selection through male–male competition, female choice and/or sexual conflict over mating frequency. In many orb-weaving spiders, mating interactions are characterized by sexual cannibalism, which has been hypothesized to drive the evolution of male morphology and mating behaviour in this group. Here, we investigate...
متن کاملSpontaneous male death during copulation in an orb-weaving spider.
Males of some cannibalistic species of spiders and insects appear to sacrifice themselves by allowing the female to eat them, and the adaptive significance of such drastic terminal reproductive investment has recently been demonstrated for a spider. Typically, the female has to kill the male, but it has been suggested that males of some species in the cannibalistic orb-weaving spider genus Argi...
