Coral Bleaching And The Effect Of Disturbances On The Damselfish Community On Lizard Island, Australia, Alejandra Munoz Jan 2017

Coral Bleaching And The Effect Of Disturbances On The Damselfish Community On Lizard Island, Australia, Alejandra Munoz

Independent Study Project (ISP) Collection

Coral reefs are characterized by their dynamic ecological processes that supports a high diversity through the recruitment of marine species and temporal disturbances that can have positive effects on the system. In the face of global climate change however, coral reefs face intense coral bleaching and increased degradation as they may begin to have less time to recover between bleaching events in the near future. Little is known on the long term effects of coral bleaching and habitat degradation on reef fish communities and much less is known about the mechanisms that bring about changes to reef fish assemblages.

Pteropus Voeltzkowi And The Understory: A Study Of The Behavioral Impacts Of The Pemba Flying Fox On The Vegetation And Soil Quality Of Pemba Island, Lea Davidson Jan 2017

Pteropus Voeltzkowi And The Understory: A Study Of The Behavioral Impacts Of The Pemba Flying Fox On The Vegetation And Soil Quality Of Pemba Island, Lea Davidson

Independent Study Project (ISP) Collection

This study examines the impact of Pteropus voeltzkowi , colloquially known as the Pemba Flying Fox, on biodiversity and health of the forest ground layer. Known to serve as reforesters, high concentrations of both fruit seeds and nutrient dense guano are introduced into specific environmental locations due to the bat's behavioral patterns. Working around two roost locations, one in Ngezi Forest and the other at the Kidike conservation site near Mjini Ole, diversity of juvenile vegetation was measured and quantified. In a laboratory setting, soil samples from both sites were analyzed for impacts of guano concentration on soil chemical properties. …


The Effects Of Thermal Stress On Fluorescent Protein Expression In An Indo-Pacific Scleractinian Coral Species, Acropora Tenuis, Anna Knochel Jan 2017

The Effects Of Thermal Stress On Fluorescent Protein Expression In An Indo-Pacific Scleractinian Coral Species, Acropora Tenuis, Anna Knochel

Independent Study Project (ISP) Collection

The scleractinian coral species that so heavily define tropical coral reefs are increasingly threatened by anthropogenic global warming. Rising sea surface temperatures in combination with light stress causes the photosynthetic breakdown of the coral’s algal symbiont, Symbiodinium. Corals have developed a number of physiological responses to handle acute stressors, such as the production of ultraviolet-protecting amino acids, heat shock proteins, the ability to shift symbionts, and the production of fluorescent proteins. The latter has been thought to play a photoprotective role in the coral holobiont, and studies have shown evidence that corals orient these pigments to divert harmful light away …


Distribution, Diversity, And Den Locations Of Canidae And Hyaenidae Species Across Habitat Type At Enashiva Nature Refuge, Grace Bullington Jan 2017

Distribution, Diversity, And Den Locations Of Canidae And Hyaenidae Species Across Habitat Type At Enashiva Nature Refuge, Grace Bullington

Independent Study Project (ISP) Collection

Due to the importance of top-trophic level predators have on their environment including regulating prey species and influencing ecosystem biodiversity, it is important to monitor top-trophic level predators to understand how they shape their ecosystem. While top-trophic level predators can benefit the ecosystem, they can also cause problems for surrounding human settlements like predation on livestock. Species in the Canidae and Hyaenidae families occupy the top-trophic level and can influence their ecosystem and cause human-wildlife conflict.

This study looked at the distribution, diversity, and den locations of Canidae and Hyaenidae species at Enashiva Nature Refuge over the course of 21 …
