Document Summary
Hypothesis testing in wold spiders: brush-legged wolf spiders: Leaf litter habitat of north american forests. Females-mate only once a breeding season; males-mate multiple times every mating season. Females are cryptic their coloration lets then blend well with the leaflitter. Males search for female using chemical cues that female deposit on silk threads in the leaf litter. When males find female, they court them with: providing visual cues: walking rapidly in jerky fashion while waving and tapping their forelegs, seismic cues: transmit vibrations through the substrate by rubbing special organs together. These signals might also be used by other nearby males as a cue to the presence of a potential mate: george uetz, andy roberts, and dave clark: Research hypothesis: male wolf spiders use the behaviour of nearby males to find receptive females. Null hypothesis: males do not use the presence and behaviour of other males as a cue to locate receptive females.
