The Effect of Hunger and Multiple Chemical Cues on the Foraging Behavior of the Wolf Spider Pardosa Milvina (Araneae, Lycosidae)

Koper, Marlena

Abstract Details

2003, Master of Science, Miami University, Zoology.
The decision to obtain food can affect the fitness of an animal. Theory suggests that the present state of an animal may affect whether or not an animal performs a given behavior. I found that hungry wolf spiders (Pardosa milvina) were significantly more active and demonstrated a greater propensity to forage than spiders that were well-fed. This increased activity is predicted to result in higher rates of mortality due to predation. Since P. milvina is known to respond to chemical cues left by other organisms in its environment I also explored the effects of both hunger and environmental cues on activity level and foraging behavior. Across cue treatments, food-limited spiders were significantly more active and demonstrated a greater propensity to forage than well-fed spiders. These results suggest that the effects of hunger may override the presence of environmental cues.
