Liquid crystalline spinning of spider silk
Spider silk has outstanding mechanical properties despite being spun at close to ambient temperatures and pressures using water as the solvent. The spider achieves this feat of benign fibreExpand

Sexual dimorphism and distorted sex ratios in spiders
SEXUAL dimorphism in body size is widespread in the animal kingdom. Whereas male giantism has been studied and explained extensively1,2, male dwarfism has not. Yet it is neither rare3–7 nor withoutExpand

Movements and corridors of African elephants in relation to protected areas
Understanding how mammals satisfy their need for space in fragmenting ecosystems is crucial for ecosystem conservation. Using state-of-the-art global positioning system (GPS) technology we tracked 11Expand

Design Variability in Web Geometry of an Orb-Weaving Spider
We studied the effect of several variables (environmental and physiological) on web geometry in the garden cross spider Araneus diadematus. Variables were: web support, wind, temperature, humidity,Expand

The molecular structure of spider dragline silk: Folding and orientation of the protein backbone
The design principles of spider dragline silk, nature's high-performance fiber, are still largely unknown, in particular for the noncrystalline glycine-rich domains, which form the bulk of theExpand

Modulation of the mechanical properties of spider silk by coating with water
THE orb web of the garden cross spider Araneus diadetnatus is made up of two types of thread with distinctive mechanical properties: stiff radial threads which sag when contracted by only 10%, andExpand

Spider silk protein refolding is controlled by changing pH.
Spidroins, the major silk proteins making up the spider's dragline silk, originate in two distinct tissue layers (A and B) in the spider's major ampullate gland. Formation of the complex thread fromExpand

Thread biomechanics in the two orb-weaving spiders Araneus diadematus(Araneae, Araneidae)and Uloborus walckenaerius(Araneae, Uloboridae)
The absorption of high kinetic energy by a small amount of material depends not only on the quality of the material but also on the structural design of the elements involved. Using a rapid responseExpand

Compounds in the droplets of the orb spider's viscid spiral
THE orb web of the garden spider Araneus diadematus, like those of other ecribellate orb spiders, relies on the remarkable extensibility of its sticky capture spiral to intercept and entrap prey1,2.Expand

Variability in the mechanical properties of spider silks on three levels: interspecific, intraspecific and intraindividual.
The mechanical characteristics of dragline silks collected from a range of spiders drawn from the Argiopidae, Tetragnathidae, Theridiidae and Pisauridae displayed significant inter- and intraspecificExpand
