Defaecation behaviour of Argiope aurantia (Araneae: Araneidae)
نویسندگان
چکیده
We examined the defaecation behaviour of Argiope aurantia both in natural situations and in a greenhouse. The spiders defaecated more frequently at night than during the day. The nightly pattern of defaecation was not related to time of feeding. A. aurantia displayed at least two distinct behaviours related to defaecation, one of which involved leaving the web. These results are discussed in relation to endogenous biological rhythms, daily patterns of activity, and predator avoidance.

Phylogeography of a good Caribbean disperser: Argiope argentata (Araneae, Araneidae) and a new ‘cryptic’ species from Cuba
The Caribbean islands harbor rich biodiversity with high levels of single island endemism. Stretches of ocean between islands represent significant barriers to gene-flow. Yet some native species are widespread, indicating dispersal across oceans, even in wingless organisms like spiders. Argiope argentata (Fabricius, 1775) is a large, charismatic, and widespread species of orb-weaving spider ran...
متن کاملFunction of bright coloration in the wasp spider Argiope bruennichi (Araneae: Araneidae).
There are two major competing explanations for the counter-intuitive presence of bright coloration in certain orb-web spiders. Bright coloration could lure insect prey to the web vicinity, increasing the spider's foraging success. Alternatively, the markings could function as disruptive camouflage, making it difficult for the insect prey to distinguish spiders from background colour variation. ...

The occurrence and patterns of stabilimenta in 1195 webs of the orb weaver Argiope appensa (Walckenaer) from four islands in the Mariana Archipelago were recorded. Webs on the largest and southernmost island, Guam, had significantly fewer stabilimenta (16.4%, n = 359) than webs of conspecifics from the neighboring islands of Rota (56.9%, n = 211), Tinian (41.9%, n = 315), and Saipan (50.3%, n =...
متن کاملBroken genitals function as mating plugs and affect sex ratios in the orb-web spider Argiope aurantia
Background: To curtail competition with their own sperm, males of several spider and insect species mutilate their genitals or sacrifice themselves entirely using their genital parts or their whole dead bodies as mating plugs. The orb-web spider, Argiope aurantia, is a species characterized by both male self-sacrifice and extreme female-biased sexual size dimorphism. Plugs may reduce female mat...
