Structural engineering of an orb-spider's web

Article Abstract:

The structural engineering features of the orb web of the garden spider Araneus diadematus are analyzed using computer simulation techniques. The techniques include the stress-strain features of the web-silk, which are dependent on time. The orb webs are built by spiders to capture large- and fast-moving insects. Aerodynamic damping is used for the capture of the fast moving prey.

Involvement of Notch and Delta genes in spider segmentation

Article Abstract:

Spider segmentation and the involvement of Notch and Delta genes are discussed. It is currently debated whether segmentation in different animal phyla has a common origin and shares a common genetic mechanism.

Spider manipulation by a wasp larva

Article Abstract:

The larva of the ichneumonid wasp Hymenoepimecis sp. induces its spider host to build a cocoon web to act as a support for the wasp larva's cocoon.
