Behavioral Disparities Between Two Troops Of Lemur Catta That Occupy Different Habitats, Laura Saucier
Behavioral Disparities Between Two Troops Of Lemur Catta That Occupy Different Habitats, Laura Saucier
Independent Study Project (ISP) Collection
The present study was conducted during the early wet season at Berenty Private Reserve. It investigates behavioral disparities between two troops of Lemur catta that occupy different habitats—gallery forest and scrub. Methods included density and phenology analysis to evaluate relative food availability in each territory. Behavioral observations were collected across eleven full-day troop follows. Results show extensive, statistically significant differences between behavior in the gallery and the scrub, many of which can be explained by relative food abundance within a troop’s home range. Some trends included greater intra-troop discord and fewer inter-troop conflicts in the scrub. In addition, the troops …
Estatus Actual De Los Búhos Terrestres (Athene Cunicularia) En La Zona De Puerto López, Ecuador: Efectos De Las Creencias Y Sentimientos Hacía Los Animales Silvestres, Allison Qubain
Independent Study Project (ISP) Collection
In response to negative attitudes towards the existing biodiversity in the region of Puerto Lopez, Ecuador and as a follow-up of a study conducted in 2006 on the status of Burrowing Owl (Athene cunicularia) populations, through informal interviews and observation, this investigation focuses on how local sentiments towards nature have affected the current status of the Burrowing Owl populations and their habitat. The investigation revealed that in addition to the effects of legends and beliefs, there is an existing lack of knowledge, understanding, and appreciation for the extremely high biodiversity, which has created an evident fear instilled in the people. …
Corallivorous Reef Fishes As Potential Vectors Of Coral Disease Based On A Study Of Dietary Preferences, Tanya Rogers
Corallivorous Reef Fishes As Potential Vectors Of Coral Disease Based On A Study Of Dietary Preferences, Tanya Rogers
Independent Study Project (ISP) Collection
The prevalence of coral disease appears to be increasing worldwide, although little is known about how these diseases are transmitted between coral colonies. To examine whether corallivorous fishes could potentially act as disease vectors, this study examined whether and which fish species feed on diseased coral, and whether these fishes actively target diseased coral sections. Branches of Acropora muricata with brown band disease were filmed in the field, and bites taken by fishes on different sections of the coral (live tissue, tissue margin, disease band, dead skeleton, and algae) were recorded. For each fish species, electivity indices were calculated for …
The Stallion's Mane: The Next Generation Of Horses In Mongolia, Amanda Hund
The Stallion's Mane: The Next Generation Of Horses In Mongolia, Amanda Hund
Independent Study Project (ISP) Collection
Horses play a central role in Mongolian history and culture, yet there has been little academic research on breeding methods, either traditional or modern in Mongolia. The goal of good horse breeding is to maintain and improve the quality of the breed. By looking at the traditional breeding, we gain a better understanding of what Mongolian culture values in their horses and what they are hoping to pass on to the next generation. We can also learn how this information is passed on in an oral tradition from generation to generation of horse trainers and herders. In traditional Mongolian horse …
Flowers And Feeders: A Comparison Of Hummingbird Feeding Activity, Caitlin A. Mchugh
Flowers And Feeders: A Comparison Of Hummingbird Feeding Activity, Caitlin A. Mchugh
Independent Study Project (ISP) Collection
Hummingbird feeders are the best way to see high species abundance and diversity, but few studies examine the differences in species abundance, diversity, feeding patterns, and aggression between flowering plants and artificial feeder sites within the same habitat. Are there significant affects on local hummingbird ecology by the presence of feeders? This paper explores possible answers to this question by investigating discrepancies between the two types of site and the implications of said discrepancies. A high count method was used to estimate species abundance and diversity along with qualitative observation was used to analyze aggression. The study found that, in …
Glandular Secretions Of Male Pteropus (Flying Foxes): Preliminary Chemical Comparisons Among Species, Jamie Wagner
Glandular Secretions Of Male Pteropus (Flying Foxes): Preliminary Chemical Comparisons Among Species, Jamie Wagner
Independent Study Project (ISP) Collection
Chemosignaling – passing information by means of chemical compounds that can be detected by members of the same species – is a very important form of communication for most mammals. Flying fox males have odiferous marking secretions on their neck-ruffs that include a combination of secretion from the neck gland and from the urogenital tract; males use this substance to establish territory, especially during the mating season. The secretions of flying fox males from three Australian species – spectacled (Pteropus conspicillatus), grey-headed (P. poliocephalus), and black (P. alecto) – were compared using high pressure liquid chromatography (HPLC); two spectacled females …
Prey Selectivity Of Planktivorous Fish: Analysis Of Stomach Contents In Four Pomacentrids At Lizard Island, Great Barrier Reef, James O'Hare
Prey Selectivity Of Planktivorous Fish: Analysis Of Stomach Contents In Four Pomacentrids At Lizard Island, Great Barrier Reef, James O'Hare
Independent Study Project (ISP) Collection
Coral reef planktivores are important to coral reefs by concentrating and delivering nutrients and allochthonous carbon from the plankton to reef building corals. In an otherwise very oligotrophic system this function may be of major importance. Planktivorous Damselfish (Pomicentridae) were analysed for prey selectivity through enumeration of stomach contents. Simultaneous plankton tows were conducted to establish the plankton community composition of the waters they were taken from. There was a statistically significant variation between the stomach composition and that of the water column. While there was not a significant difference among Simpson’s diversity indices of the stomach contents, there was …
Heifer Tanzania’S Alternate Training Methods: A Study Comparing The Dairy Cow Husbandry Practices Of Farmers Trained In Their Villages By Project Supervisors To Those Of Farmers Trained By The Liti Tengeru Animal Husbandry Training Center, Ciara Lowery
Independent Study Project (ISP) Collection
This study was conducted in nine villages near Mount Meru, Tanzania between 14 April 2008 and 1 May 2008. The study question and methods were developed in conjunction with Heifer Tanzania. Heifer is a non-profit organization that provides dairy-cattle and other livestock to farmers in need. Heifer’s agents also provide training in sustainable farming techniques, such as zero-grazing livestock husbandry, and building contours. Some farmers receive this training in their village from a project supervisor, and other farmers are sent to a government facility, Liti Tengeru Animal Husbandry Training Center. The aim of this study was to determine what differences …

Aquatic And Terrestrial Habitat Use Of The Australian Freshwater Turtle, Chelodina Expansa, Ellyn Ercolano
Independent Study Project (ISP) Collection
Organisms select habitats that provide the best possible resources necessary to their survival. Organisms may occupy and utilize a home range which requires specific selection of components in their available habitat. Monitoring the threats to a species within their habitats is a crucial tool in conservation and management practices. The Murray-Darling Basin of south-eastern Australia has suffered alterations to its hydrology, flow regime, catchment size and usage, flooding cycles, as well as from vast removal of vegetation in the floodplains since European settlement in Australia in the mid-nineteenth century. Knowledge of the habitat use of a focal species can guide …
