Spontaneous 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...
متن کاملCompeting dwarf males: sexual selection in an orb-weaving spider.
Hypotheses for the adaptive significance of extreme female-biased sexual size dimorphism (SSD) generally assume that in dimorphic species males rarely interfere with each other. Here we provide the first multivariate examination of sexual selection because of male-male competition over access to females in a species with 'dwarf' males, the orb-weaving spider Argiope aurantia. Male A. aurantia t...
متن کاملOrb-weaving spider diversity in the Iberá Marshlands, Argentina.
The Iberá Marshlands RAMSAR reserve, in the northeast of Argentina, is one of the largest and most important wetlands of America. In this study we assess orb-weaving spider (Araneae: Orbiculariae) diversity in this reserve, analyzing different facets of local diversity (species richness, diversity, evenness and taxonomic distinctness), and the contribution of species differentiation (beta diver...
متن کاملResting Postures of Orb-weaving Uloborid Spider S (araneae, Uloboridae )
Observations of 22 orb-weaving species of the family Uloboridae show that these spiders assum e one of four basic resting postures as they hang beneath the web's hub . The primitive pattern found in Tangaroa and Octonoba is characterized by all legs being spread and about equally flexed, whereas i n Zosis the protracted first legs grasp the web at nearly the same point . Uloborus species typica...
متن کاملThe Landmark Spider: Weaving the Landmark Web
Landmarks play an important role when humans navigate through foreign environments (Lynch, 1960; May, Ross, Bayer, and Tarkiainen, 2003). For example, trying to find the way is much easier if the navigator can rely on a description of the route based on well-recognizable objects in the environment, instead of navigating solely on the basis of street names and metric directions (Tom, and Denis, ...
