Super‐Tough Silk: The Potential of Knots in Evolved Spiders
The toughness of spider silk can be further significantly enhanced if spiders evolved the –currently absent/undiscovered– ability to tie knots in their silk. The results on 393 spiders suggest toughness increments by one or two orders of magnitude and thus a new perspective on how knotting can serve as a key innovation in spider evolution and in ...

Effects of the wasp-spider, Argiope bruennichi, on planthoppers and leafhoppers
The role of spiders as generalist predators of herbivores is an important issue for prey population dynamics and spatial distribution. We conducted a field experiment in order to study the effects of the web-building spider Argiope bruennichi on plant- and leafhoppers in a grassland habitat. Spider densities were manipulated through repeated removal in

Abstract Due to widespread atmospheric deposition of mercury (Hg), all aquatic food webs are contaminated with toxic methyl mercury (MeHg). At high concentrations, MeHg poses a health hazard to wildlife and humans. Spiders feeding in riparian habitats (hereafter referred to as riparian spiders) have been proposed as sentinels of MeHg contamination of ...

Comparative neuroanatomy of the central nervous system in web‐building and cursorial hunting spiders
In this study, we describe the central nervous system of two cursorial hunting spiders and two stationary hunting spiders. We found major differences in the secondary eye pathway between species that pertain to visual neuropils and higher‐ order neuropils. We also found differences in the proportional volume of neuropils.

Rapid spread of the wasp spider Argiope bruennichi across Europe: a consequence of climate change? [PDF]
Numerous species are expanding their ranges towards the North Pole, a pattern that is usually explained with climate change. However, few studies have actually tested the potential role of climate in such range expansions.

Direct and indirect bottom-up and top-down forces shape the abundance of the orb-web spider Argiope bruennichi [PDF]
Species abundance in local communities is determined by bottom-up and top-down processes, which can act directly and indirectly on the focal species. Studies examining these effects simultaneously are rare.
