Effects of neurotoxins on orb webs

Drug webs
The project was about web-building behaviour and web-geometry of orb-weaving spiders. The research focused on the garden cross spider, but also included catching and maintaining populations of other orb-weaving spiders in the laboratory. The project was split into two parts. The first part investigated the effects of neurotoxins such as amphetamine, caffeine and scopolamine and temperature on the geometry of the web as well as web-building behaviour of the spider. The second part involved examining the effects of temperature on prey escape time and spider capture time in orb webs. The research methods included automated computer tracking of spiders from video recordings, drug administering and image analysis.
