Description
Human-induced rapid environmental change, or HIREC, has a dramatic influence on biodiversity loss in areas with significant anthropogenic activity. Urbanization is an example of HIREC that can result in the proliferation of some species and the local extinction of others in urban spaces. The ability of a species to survive HIREC, or urbanization, is determined through a species' ability to respond to a disturbed environment. Species respond to novel environments through plasticity, genetic evolution, or an evolution of plasticity. The manner in which a species responds depends on the available resources within their environment such as food availability and mate availability. We investigated the influence of female pheromonal cues and prey abundance on the male development of the western black widow, Latrodectus hesperus. L. hesperus is an ideal candidate for this study because they can respond to female silk pheromonal cues and are an abundant, polyphagous predator in Phoenix, AZ. We hypothesized that the presence of female silk and high amounts of prey would influence the development of males therefore both variables would speed the development of males. It was found that the presence of silk had a marginally nonsignificant effect on decreasing foraging voracity of males as well as decreasing the lifespan of males. It was also found that a high abundance of prey had a significant effect on decreasing foraging voracity and lifespan. The interaction between food abundance and silk presence had a marginally nonsignificant influence on the mass at death. It is proposed that high food treatments had a higher mortality rate due to receiving a poor-quality nutrition diet through fruit flies, Drosophila melanogaster.
