Young juveniles of L. geometricus fit the strong trend for “ontogeny to repeat phylogeny” previously documented in other web-building spiders; younger spiders were less likely to build the derived silk retreats that occur ...

A new species of the orb-weaving spider genus Aculepeira Chamberling & Ivie 1942, A. morenoae new species, is described and illustrated based on male and female specimens from the Argentinean natural flooding pampas grasses.

Orb-weaving spiders can produce different silk fibers, which constitute outstanding materials characterized by their high strength and elasticity. Researchers have tried to reproduce the fibers of these proteins synthetically ...

I examined the potential genetic and environmental determinants of population differences in the foraging behaviour of the colonial spider Parawixia bistriata by using reciprocal transplant and prey manipulation experiments. ...

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, ...

Behavior can provide useful traits for testing phylogenetic hypotheses, and some details of orb web construction behavior have been especially useful in characterizing higher-level groups in spiders. The cues used to guide ...

Many orb-weaving spiders break the central lines of the hub at the end of web construction. Nevertheless, very little is known of how spiders break these lines and whether this behaviour differs among taxa. Here, we describe ...
