Corallivorous Reef Fishes As Potential Vectors Of Coral Disease Based On A Study Of Dietary Preferences, Tanya Rogers Oct 2008

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 …


Improving Beekeeping On Unguja Island, Larken Root Oct 2008

Improving Beekeeping On Unguja Island, Larken Root

Independent Study Project (ISP) Collection

The purpose of this study was to investigate the current practices and methods for improvement of beekeeping on Unguja Island in Zanzibar. Beekeeping has been occurring for many years in Unguja but has retained traditional techniques with little improvement. Improvement can occur in the form of introduction of modern equipment, formation of beekeeping organizations, advancing and diversifying products, and gaining governmental support. Beekeeping is worthy of expansion because of its potential to increase rural income in a sustainable way as well as support conservation of forest areas. The study found that there has so far been little improvement of income …


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 Oct 2008

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. …


A Reassessment Of Avian Assemblages Along The Lakes Corridor In The Atherton Tablelands, North Queensland, Shaina N. Stewart Apr 2008

A Reassessment Of Avian Assemblages Along The Lakes Corridor In The Atherton Tablelands, North Queensland, Shaina N. Stewart

Independent Study Project (ISP) Collection

Forest fragmentation is the process by which large areas of continuous forest are replaced by foreign ecosystems that restrict native growth to isolated patches. Biota remaining within these fragmented environments often suffer consequences that stem from reduced forest area. Wildlife corridors—linear patches of habitat that connect remnant fragments—have frequently been proposed to alleviate fragmentation effects by facilitating biotic movement between forest patches. Initiated in 1998, the Lakes Corridor on the Atherton Tablelands in North Queensland, Australia, connects the two formerly isolated sections of Crater Lakes National Park with the goal of promoting wildlife dispersal between them. This study monitored avian …


Post-Fire Demography Of A Dry Eucalypt Forest In The Midlands, Tasmania: A Pilot Study, Christine Urbanowicz Apr 2008

Post-Fire Demography Of A Dry Eucalypt Forest In The Midlands, Tasmania: A Pilot Study, Christine Urbanowicz

Independent Study Project (ISP) Collection

There have been many efforts to regenerate the threatened and declining dry eucalypt forests found within the Midlands of Tasmania. This pilot study was completed as part of a larger research project on eucalypt regeneration. Researchers need to know where recruits are most successful in order to appropriately place regeneration microsites. I have begun characterizing the baseline demography of a recently burnt remnant forest. I had two objectives: 1. to characterize the stand structure where recruits are successful, and 2. to describe where the recruits are within this structure. Data on location, size, and life history stage of trees were …
