Dispersal patterns of the cellar spider in response to manipulated sex ratios and density

The cellar spider, Pholcus manueli (Araneae, Pholcidae), has recently expanded its range and is now abundant throughout the Midwest. However, little is known about its biology and especially factors that might influence its dispersal. Studying P. manueli dispersal patterns should shed light on whether an individual can assess its environment and what factors might be important in the decision to disperse from an area. In a laboratory experiment, I observed both males and females dispersing from an environment perceived to be male dominant. In a field study, I observed that neither sex ratios nor density had a significant effect on the likelihood of dispersal. However, when comparing the amount of dispersal in the male and female biased populations, there again tended to be more dispersal in male dominated enclosures. Therefore, movement of these spiders between patches is caused, at least in part, by the demography of the population.
