- Title
- Anurans of Abacoa.
- Creator
- Vuong, Wei Mien., Harriet L. Wilkes Honors College
- Abstract/Description
-
The construction of Abacoa included an attempt to conserve the wildlife in a Greenway, a set of habitats separated from the residential and commercial areas. All of the wetlandswith in Abacoa represent artificially constructed ponds, canals, and streams first created from 1998-2004. The present study focuses on the anuran (i.e., frog and toad) populations and looks at the number of different species that have naturally colonized six differnet sites around Abacoa. Each of these sites varies in...
Show moreThe construction of Abacoa included an attempt to conserve the wildlife in a Greenway, a set of habitats separated from the residential and commercial areas. All of the wetlandswith in Abacoa represent artificially constructed ponds, canals, and streams first created from 1998-2004. The present study focuses on the anuran (i.e., frog and toad) populations and looks at the number of different species that have naturally colonized six differnet sites around Abacoa. Each of these sites varies in qualities that may affect the probability of breeding in that section. The quality of water is known to be less ideal as the water flows away from the headwaters and mixes with water from other sources. This study aims to determine which anuran species are found at each of these sites after nearly a decade of colonization, and how both anuran diversity and abundance correlates with water and habitat quality.

- Title
- Declining coral health and fish diversity in the South Pacific.
- Creator
- McCurdy, Paul., Harriet L. Wilkes Honors College
- Abstract/Description
-
Coral reefs harbor ~1-9 million species, including 30% of all marine fish species. Reef health worldwide is declining due to many factors: e.g. pollution, sedimentation, dynamite fishing, and global warming. Working with the Planetary Coral Reef Foundation and the crew aboard the R/V Heraclitus, I examined coral health and fish diversity in the Solomon Islands, Melanesia. In 2006, I surveyed coral and fish on Sagharughombe reef, Solomon Islands using SCUBA and compared the results with...

Reef health worldwide is declining due to many factors: e.g. pollution, sedimentation, dynamite fishing, and global warming. Working with the Planetary Coral Reef Foundation and the crew aboard the R/V Heraclitus, I examined coral health and fish diversity in the Solomon Islands, Melanesia. In 2006, I surveyed coral and fish on Sagharughombe reef, Solomon Islands using SCUBA and compared the results with surveys done in 2000 and 2002. Coral surveys indicated a significant decline in health over the six-year period. Fish surveys found no clear trend in species abundances and species richness, but a significant decline in species diversity over the years. The decline in coral health we observed may have contributed to diminished fish diversity. To protect marine biodiversity, coral reefs must be better protected and declines in coral health must be halted.

- Effects of prescribed burning on native and exotic herpetofauna in Florida pine flatwoods in Savannas Preserve State Park.
- Creator
- Goethel, Carrie Ann., Harriet L. Wilkes Honors College
- Abstract/Description
-
Florida's pine flatwoods are pyrogenic ecosystems that require frequent fires to regenerate the herbaceous layer and suppress crowding vegetation. Human development has hindered these natural fires and consequently affected the herpetofauna (amphibian and reptile) species. Anthropogenic encroachment, in addition to fire suppression, has also provided ideal habitats for invasive species within native environments. Exotic species are often found in developed areas around buildings and roads,...
Show moreFlorida's pine flatwoods are pyrogenic ecosystems that require frequent fires to regenerate the herbaceous layer and suppress crowding vegetation. Human development has hindered these natural fires and consequently affected the herpetofauna (amphibian and reptile) species. Anthropogenic encroachment, in addition to fire suppression, has also provided ideal habitats for invasive species within native environments. Exotic species are often found in developed areas around buildings and roads, and it is likely this pattern continues into the park. This eight-month coverboard survey focuses on the effects various fires may have on herpetofauna in the area and explores the level of intrusion exotic species exhibit within the communities. Minimal differences among herpetofauna composition between transects were found. However, a convincing percentage of exotic species were found only within the first ten meters of the transects while all native species were at least 25 meters into a transect.

- McKee, Kristy., Harriet L. Wilkes Honors College
- Abstract/Description
-
Freshwater marshes are a harsh wetland ecosystem classified by seasonal water level fluctuation. Dry down periods are common in some marshes, making life difficult for fish and other aquatic organisms. The goal of this study was to compile an updated species list of fishes inhabiting the freshwater marsh system within Savannas Preserve State Park. Twenty-three fish species were collected between August 2005 and May 2007. This survey, along with past collections, and the current species list...

Dry down periods are common in some marshes, making life difficult for fish and other aquatic organisms. The goal of this study was to compile an updated species list of fishes inhabiting the freshwater marsh system within Savannas Preserve State Park. Twenty-three fish species were collected between August 2005 and May 2007. This survey, along with past collections, and the current species list in the park's management plan were used to make a new proposed species list. Three species of nonnative fishes were observed during the study, the first report of exotic fishes in the park. It is believed that abnormally high water levels for an extended period may have allowed the water in neighboring canals to connect to the marsh system and, as a result, new species were able become introduced in the park.

- Canache, Christian., Harriet L. Wilkes Honors College
- Abstract/Description
-
Prior to 2000, very little was known about fish biodiversity on the New England Seamount chain. In late 2000, 115 fish species were found on Bear Seamount by the NOAA R/V "Delaware II." Woods Hole Oceanographic Institution conducted two cruises to explore the New England Seamount chain in 2003. This study assessed fish species throughout Alvin submersible dives during these 2003 cruises. Digital video footage was converted to still photographs and video clips using the Macintosh movie program...

Woods Hole Oceanographic Institution conducted two cruises to explore the New England Seamount chain in 2003. This study assessed fish species throughout Alvin submersible dives during these 2003 cruises. Digital video footage was converted to still photographs and video clips using the Macintosh movie program iMovie. Fishes were identified to the lowest possible taxonomic level using keys and literature. The habitat, depth and behavior of observed fishes were compared to the literature available. Geographical distributions of the species were considered. I assessed substrate preference by building a chart that reflects the different sediment regimes that fishes were found on. In all I identified 317 individuals representing 33 different taxa, including two species with new habitat range information Neocyttus helgae and Lepidion sp.

- Abstract/Description

Sorites dominicensis is a common epiphytic foraminifera living throughout the Carribean and South Florida, and is commonly found living on turtle grass, Thalassia Testudinum. S. dominicensis plays host to algal symbionts related to those found in coral. Estimates for the numbers in these symbiotic populations are few, of limited scale, and vary widely. In this thesis we performed a large scale survey of the populations of algal symbionts living within the S. dominicensis population of Jupiter...

S. dominicensis plays host to algal symbionts related to those found in coral. Estimates for the numbers in these symbiotic populations are few, of limited scale, and vary widely. In this thesis we performed a large scale survey of the populations of algal symbionts living within the S. dominicensis population of Jupiter Sound. We then used this data to propose a linear model for the relationship between foraminiferal size and endosymbiont population, and to suggest explanations for the variability seen in the Jupiter Sound population.
