I Ain't Afraid Of No Crab: Intertidal Gastropod Littorina Littorea Behavioral Response To Predation Risk By Carcinus Maenas, Isabelle Erin Smy
I Ain't Afraid Of No Crab: Intertidal Gastropod Littorina Littorea Behavioral Response To Predation Risk By Carcinus Maenas, Isabelle Erin Smy

Littorina littorea is an intertidal, invasive gastropod species common in the Gulf of Maine. In this paper, I studied the avoidance and risk-reducing behavioral responses of L. littorea to predation risk by invasive crustacean species Carcinus maenas. Avoidance and risk-reducing behavior in this study are defined by the tendency to move towards the edge and out of a simulated tide pool and the tendency to reduce feeding. The goal of this study was to determine whether the exposure to chemical cues of predators resulted in an increase in avoidance behavior, risk-reducing behavior, and a reduction in the time before the …

Previous studies have shown that scatter-hoarding small mammals increase seed germination success through the process of collecting and caching seeds throughout the forest. This study seeks to explore this further by examining how specific cache microsite preferences among these small mammals impacts the germination and growth of northern red oak (Quercus rubra). Seeds were planted in six different microsites across three forest treatments. Germination, seedling height, and herbivory were then monitored over time. We found that microsite did not have a significant effect on germination or height, however microsite did impact herbivory probability, and open microsites made seedlings more vulnerable …
