This study looks at huddling behavior in several groups of Eulemur rubriventer in Ranomafana National Park, Madagascar, in order to compare the functions of huddling in relation to thermoregulation and social bonding. The proportions of time spent huddling as functions of rainfall and ambient temperature were used to explore the possibility of huddling as a means of thermoregulation. A positive relationship between loose huddling behavior and temperature was deemed significant. Data collected on proximity of individuals to each other (nearest neighbor) was able to establish a significant correlation …

Novelty Interactions Between Herbivorous Fish And Sargassum: Insight Into Macroalgal Phase Shifts, Christopher Pickens

Independent Study Project (ISP) Collection

Herbivores play a key role in the maintenance of algal and coral communities. A reduction in herbivory has been shown to result in a shift to a macroalgae dominated system, which can have significant effects on the biodiversity and restorative capabilities of coral reefs. Several studies have been done to better understand how herbivorous communities respond to macroalgae. These have shown that only certain herbivorous taxa are capable of removing macroalgae and there are several factors (depth, density, etc.) that affect the susceptibility of macroalgae to herbivory. However, few studies have yet to determine if the novelty of the resource …

Effects Of A Cymothoid Ectoparasite On The Turning Behavior (Lateralization) Of The Bridled Monocle Bream Scolopsis Bilineata, Laura Strong

Independent Study Project (ISP) Collection

Lateralization, or behavioral asymmetry, is the tendency to favor one side of the body over the other, and exists in humans and animals including in mammals, birds, and fishes. It has been found to increase performance in certain behaviors such as escape from predators by lowering reation time. Lateralization has predominantly genetic bases, but can also be influenced by environmental factors. For example, lateralization has been observed to increase in populations of fish subject to high predation pressure as it decreases their response time to predatory attacks. Parasitism may also have important effects on lateralization. In particular, increased drag from …

Coarse Woody Debris In A Tropical Rainforest In North Queensland, Australia: Relationships With Stand Structure And Disturbance, Nadine Rea

Independent Study Project (ISP) Collection

Coarse woody debris (CWD) refers to the woody material on the forest floor, including fallen stems, large branches, coarse roots, wood pieces, and standing dead trees (snags) (Harmon et al. 1986). CWD is an essential but often overlooked aspect of ecosystems. It plays many key ecosystem roles and is instrumental in overall ecosystem functionality. While a piece of CWD decomposes, it provides key habitat for many different species, minimizes soil erosion, affects soil development, stores nutrients and water, and influences the global carbon cycle (Harmon and Hua 1991). In some forests, CWD can exist on the forest floor for hundreds …
