Controlling The Dengue Mosquito (Aedes Aegypti): Assessment Of The Effects Of Metofluthrin, A Novel Vapor-Active Pyrethroid, On Mosquito Behavior In A Modeled Domestic Setting., Randy Kring

Independent Study Project (ISP) Collection

Dengue fever is a potentially life-threatening illness that is endemic in over 100 countries and threatens approximately half of the world’s population. The dengue virus is transmitted between humans by a mosquito vector, principally the dengue mosquito, Aedes aegypti. This mosquito prefers to live and feed in and around people’s homes. As a result, preventing mosquito bites within a domestic setting is essential to controlling the dengue virus. Although several methods of bite prevention are currently available to the public, most of these methods only provide short-term protection from the dengue mosquito. In contrast, a recently developed synthetic pyrethroid called …

Prevalence And Intensity Of Trypanosome Infections In Stable And Declining Populations Of Brush-Tailed Bettongs (Bettongia Penicillata), Melissa Chiasson

Independent Study Project (ISP) Collection

The brush-tailed bettong (Bettongia penicillata), or woylie, is an endemic Australian marsupial that has recently suffered a large population crash in the Upper Warren region of Western Australia. Research has shown that both the declining Upper Warren population of brush-tailed bettongs and a stable population at Karakamia Wildlife Sanctuary are infected with a novel Trypanosoma sp., and the declining Upper Warren population was found to have a higher prevalence of trypanosome infection that that of the stable Karakamia population. In this study, further work was done to see if 1) the prevalence and intensity of trypanosome infection still differed significantly …

Effects Of Re-Grown Forest Habitat On Lemur Catta Behavior, Sophie Ackoff

Independent Study Project (ISP) Collection

This study examines the effects of re-grown forest habitat on L. catta behavior at Berenty Private Reserve in Southern Madagascar during the early wet season. Evaluation of the reforested area versus natural forest revealed significant differences in species composition and food availability. Though the re-grown forest showed signs of forest regeneration and total greater food availability, the natural forest of Malaza proved to contain more preferred food sources for L. catta. Behavioral observations were collected over eight full-day troop follows and showed significant differences in feeding behavior, activity budget, and intra-troop and inter-troop aggressions. The WELL troop in Ankoba, the …

Mangroves And Crabs As Ecosystem Engineers In Zanzibar, Charlie Nicholson

Independent Study Project (ISP) Collection

Primary productivity within mangroves results from detrital and coprophagous interactions on the forest floor. The feeding behaviors of Sesarmid crabs (Decapoda:Brachyura) alter the structural and chemical composition of benthic sediment through the consumption and incorporation of mangrove leaf-litter. In doing so they create habitats for organisms that in turn provide an additional food source for herbivorous crabs. Species specific herbivory was observed in order to understand the implications of Sesarmid activity on sediment composition. The study was conducted at two contrasting mangrove forest sites, one in a protected area at Jozani and the other in a disturbed area at Pete …

Independent Study Project (ISP) Collection

“The king of this place could be Bear; it can capture and eat anything, even roe deer and moose. But I think sometimes Bear is eaten by Wolf, working as a pack. It means that Wolf is the king of the king” – Joogdernamjil, Dadal Hunter The grey wolf is a key figure in Mongolian culture, representing not only the male ancestor behind the bloodline of Chinggis Khaan, but also the messenger of heaven, sent to punish those who disrespect the spirit masters of the land. Countryside herders and UB businessmen alike honor the wolf as a spiritually powerful animal, …

Bromeliads As A Breeding Site For The Dengue Vector Aedes Aegypti, Eva B. Shultis

Independent Study Project (ISP) Collection

Dengue Fever is a major public health concern in tropical and subtropical climates worldwide, including the city of Cairns, Australia, which is currently suffering a severe outbreak. The most important vector of the Dengue virus is the predominantly urban mosquito Aedes aegypti (L.), which lays its eggs in both artificial and natural containers, including the ornamental bromeliad plants found in many household gardens. The ability of larvae to develop to adulthood inside bromeliads has become controversial, however, and bromeliad enthusiasts frequently refuse to have their plants treated with insecticide. The aim of this study was to determine the conditions under …

The Politics Of Genetically Modified Organisms: Global Rules, Local Needs, Ximena Gonzalez

Independent Study Project (ISP) Collection

Biotechnology in regards to agriculture is complex and cannot be judged by a single factor. Exporters of GM foods have their reasons for exportation, and importing countries have their reasons to accept them. There is not a unified reason for acceptance or rejection. Countries may accept or reject for economic, social, or political reasons. Other countries may accept or reject for environmental and/or health reasons. However, there is the inevitable factor of influence. Some countries like the United States, and supernational powers like the European Union are major elements to the decision making process of developing countries. When it comes …

Pomacea Canaliculata In Tram Chim National Park: An Examination Of The Golden Apple Snail Within Local Vegetation Populations, Justin Loiseau

Independent Study Project (ISP) Collection

The golden apple snail (Pomacea canaliculata) is an invasive species that was first introduced into Southeast Asia in the 1980’s. Nearly three decades later, Pomacea canaliculata has become a widespread pest that threatens several key crops of the region, including Vietnam’s expansive rice fields. Although the economic implications of the spread of Pomacea canaliculata throughout Vietnam are disastrous, the environmental implications are also quite shocking. In Tram Chim National Park, the golden apple snail has shown its ability to survive and thrive off of local grasses and wild rice. To better understand the threat level of Pomacea canaliculata to Tram …

Monkeying Around: Spatial Differences In Riverine Habitat Utilization By Vervets, Sykes, And Baboons, Sondra Lavigne

Independent Study Project (ISP) Collection

The purpose of this study was to examine where in five vertical locations (river, bank, ground, trunk, and canopy) and at what times vervet monkeys, sykes monkeys and baboons utilized the habitat of the Simba River at Ndarakwai Ranch in the West Kilimanjaro district of Northern Tanzania. The study attempted to use this information, particularly in regards to eating behavior, to see if these sympatric species use vertical special or time of day to partition the resources along the river, and if close proximity to other primates affected vertical location. The study was conducted within 25m of a 2.8km section …

Spiny Forest Heterogeneity: Implications For Regeneration And Its Detection, Catherine Reuter

Independent Study Project (ISP) Collection

This study sought to verify claims made in a recently published paper by Thomas Elmqvist that certain portions of Madagascar’s spiny forest are rapidly regenerating. The study took place in the forest around the village of Manavy located in Central Antandroy, where historical and current images of the land cover do not collaborate Elmqvist’s conclusions. Using maps derived from remote sensed images of the area, quadrats were established within Elmqvist’s ‘regenerating’ area. Within these sites detailed vegetative analyses of species composition and regenerative process were performed as well as qualitative assessment of disturbance level. The results of this study indicate …

Miti Iko Wapi Ii ?, Taylor Tully

Independent Study Project (ISP) Collection

Vegetative communities within the savannah ecosystem oscillate between grassland and woodland states. Research has found that ecological perturbations resulting from elephants, fire, other herbivores and humans have a significant influence on the oscillation of vegetative communities. Understanding these forces and how they interplay to influence vegetative dynamics states is essential to a developing any effective conservation management program. A previous study, in 2003, was conducted to establish baseline data on vegetative community structure, elephant damage and fire damage within Ndarakwai Ranch. (Hamilton and Downing 2003). However, the study drew few definitive conclusions and suggested further research. This study was a …
