Ontogenetic Changes In Feeding Ecology And Habitat Of The Damselfish Neoglyphidodon Melas At Lizard Island, Great Barrier Reef, Sai-Wing Chan
Independent Study Project (ISP) Collection
This study examines ontogenetic shift in habitat and feeding ecology of the black damselfish, Neoglyphidodon melas in three patch reef sites at Lizard Island, Great Barrier Reef. This rarely studied species is unique in its coprophagous relationship with the faeces of the giant clam Tridacna gigas. Distribution and habitat composition between three sites and two reef zones was estimated with 48 Visual Belt and Point Intercept Transects. 80 Focal Animal Studies revealed specific foraging strategies and aggressive behaviours. The timing of this study permitted the inclusion of juvenile recruits resulting in a more complete and comprehensive study across developmental stages. …

An Extraordinary Patch Of Feral Hog Damage In Florida Before And After Initiating Hog Removal, Richard M. Engeman, John Woolard, Henry T. Smith, Jean Bourassa, Bernice U. Constantin, Daniel Griffin
United States Department of Agriculture Wildlife Services: Staff Publications
Feral hogs (Sus scrofa) are a particularly destructive exotic species in the United States (U.S. Department of Agriculture 1999), including Florida, which, along with Hawaii, is one of 2 states cited as having the most severe invasive species problems (U.S. Congress 1993) in the country. First introduced to North America by the European colonists (Conover 2007) hogs were one of the first invasive exotic species to take hold in Florida. They can transmit disease to livestock (Hartin et al. 2007) and humans (Conover and Vail 2007). They impose a variety of negative environmental impacts, including habitat degradation and …

Benthic Mapping For Habitat Classification In The Peconic Estuary: Phase I Groundtruth Studies, Robert M. Cerrato, Nicole P. Maher
School of Marine & Atmospheric Sciences Faculty Publications
Benthic habitat maps of the estuary seafloor will increase our knowledge of range and variability in benthic habitats, will assist managers in their efforts to protect and/or restore commercially and recreationally important finfish and shellfish, will link land usage (e.g. developed vs. undeveloped areas) and water quality data to benthic habitat quality, and will make it possible to utilize faunal data as a long-term indicator of the overall “health” of the estuary. We are developing benthic habitat maps by combining high-resolution remote sensing techniques with detailed study of the physical and faunal characteristics at point locations in different seafloor environments. …
Ground Water Dependence Of Endangered Ecosystems: Nebraska’S Eastern Saline Wetlands, F. Edwin Harvey, Jerry F. Ayers, David C. Gosselin
Ground Water Dependence Of Endangered Ecosystems: Nebraska’S Eastern Saline Wetlands, F. Edwin Harvey, Jerry F. Ayers, David C. Gosselin
School of Natural Resources: Faculty Publications
Many endangered or threatened ecosystems depend on ground water for their survival. Nebraska’s saline wetlands, home to a number of endangered species, are ecosystems whose development, sustenance, and survival depend on saline ground water discharge at the surface. This study demonstrates that the saline conditions present within the eastern Nebraska saline wetlands result from the upwelling of saline ground water from within the underlying Dakota Aquifer and deeper underlying formations of Pennsylvanian age. Over thousands to tens of thousands of years, saline ground water has migrated over regional scale flowpaths from recharge zones in the west to the present-day discharge …

All Peer-Reviewed Publications
The mite Tetranychus evansi Baker & Pritchard (Tetranychidae) probably originated in South America. Because of its importance as a tomato pest in Africa, an extensive project has been conducted to detect potentially effective natural enemies in South America for the classical biological control of the pest in Africa. A search for the natural enemies of T. evansi was conducted in the Province of Tucumán, northwestern Argentina, in December 2004, and this report describes the results. One hundred predatory mites of the family Phytoseiidae referring to 11 species were collected on 11 examined species of solanaceous plants. The most abundant phytoseiid …

Comparison Of Immune And Adverse Effects Induced By Adjuvac And Freund's Complete Adjuvant In New Zealand White Rabbits (Oryctolagus Cuniculus), Jenny G. Powers, Paul B. Nash, Jack C. Rhyan, Christi A. Yoder, Lowell A. Miller
United States Department of Agriculture Wildlife Services: Staff Publications
Though Freund's complete adjuvant effectively increases immune response to vaccines in various species, its potentially severe inflammatory effects have led many animal researchers to seek alternative immunological adjuvants. In a study of New Zealand white rabbits, the authors compared the immune and adverse effects of Freund's complete adjuvant with the effects of two formulations of AdjuVac, an immunological adjuvant previously developed by their group. ALL three adjuvants improved humoral immune response but also caused inflammation. Inflammatory reactions caused by AdjuVac, however, tended to be Less severe than those caused by Freund's complete adjuvant.
Does Interference Competition With Wolves Limit The Distribution And Abundance Of Coyotes?, Kim Murray Berger, Eric M. Gese
Does Interference Competition With Wolves Limit The Distribution And Abundance Of Coyotes?, Kim Murray Berger, Eric M. Gese
United States Department of Agriculture Wildlife Services: Staff Publications
1. Interference competition with wolves Canis lupus is hypothesized to limit the distribution and abundance of coyotes Canis latrans, and the extirpation of wolves is often invoked to explain the expansion in coyote range throughout much of North America.
2. We used spatial, seasonal and temporal heterogeneity in wolf distribution and abundance to test the hypothesis that interference competition with wolves limits the distribution and abundance of coyotes. From August 2001 to August 2004, we gathered data on cause-specific mortality and survival rates of coyotes captured at wolf-free and wolf-abundant sites in Grand Teton National Park (GTNP), Wyoming, USA, …

Implementing Uganda’S National Wetlands Policy: A Case Study Of Kabale District, Sophie Glass
Independent Study Project (ISP) Collection
Uganda’s “National Policy for the Conservation and Management of Wetland Resources” was launched in 1995 to promote the protection of Uganda’s wetlands in order to sustain their ecological and socioeconomic functions. Despite the formal policy, wetlands continue to be drained and converted. This report examines factors that account for the divide between the National Wetlands Policy and reality. Six weeks were spent researching the challenges associated with implementing the National Wetlands Policy. Kabale District was used as a case-study to better understand the issues that institutions and stakeholders face when trying to abide by the precepts of the policy. Rapid …
Distribution Of Ultraviolet-Absorbing Sunscreen Compounds Across The Body Surface Of Two Species Of Scaridae, Elizabeth Cerny-Chipman
Distribution Of Ultraviolet-Absorbing Sunscreen Compounds Across The Body Surface Of Two Species Of Scaridae, Elizabeth Cerny-Chipman
Independent Study Project (ISP) Collection
Ultraviolet radiation has far-reaching effects in marine ecosystems, but many marine organisms have UV-absorbing compounds that protect them from sun-induced damage. The mucus of coral reef fish has been found to contain mycosporine-like amino acids that absorb UV light from 309-360 nm. Using UV spectrophotometry, we examined whether fish are able to allocate these MAA sunscreen compounds to areas of the body that receive the most UV radiation. We compared absorbance spectra of mucus from the body surface of dorsal, ventral, caudal and head areas in two species of Scaridae (Scarus schlegeli and Chlorurus sordidus) from Coral Bay, Western Australia. …

Effects Of Human Choices On Characteristics Of Urban Ecosystems, Lawrence A. Baker, Anthony J. Brazel, Loren Bryne, Alex Felson, Morgan Grove, Kristina Hill, Kristen C. Nelson, Jason Walker, Vivek Shandas
Institute for Sustainable Solutions Publications and Presentations
Most urban ecology in cities remains an "ecology in cities" rather than an "ecology of cities." Accomplishing the latter requires the inclusion of humans within the concept of "ecosystem," both how humans alter the properties of urban ecosystems and how these alterations in turn influence human well-being. These influences are both direct (e.g., physiological and psychological influences on the human organism) and indirect, by influencing ecosystem sustainability. For the 2007 ESA meeting, Larry Baker, Loren Byrne, Jason Walker, and Alex Felson organized a symposium to address the relationships among human choices and urban ecosystems. In the introductory talk of this …

Population Biology And Monitoring Of The Cuban Hutia At Guantanamo Bay, Cuba, Gary W. Witmer, Martin Lowney
United States Department of Agriculture Wildlife Services: Staff Publications
The Cuban hutia (Capromys pilorides) is the largest native mammal occurring in Cuba. Endemic to the West Indies, most species of hutia are rare or extinct because of over-harvesting, exotic species introductions, and habitat modifications by humans. An exception is Guantanamo Bay, Cuba, where the Cuban hutia is very common and is responsible for a variety of damage and conflicts, including damage to landscaping, gnawing through cables, damage to vehicles, the accumulation of large amounts of feces in residential areas, and damage to native vegetation, with little subsequent regeneration of many plant species. Current management focuses on population …

A Successful Case Study: The Bird Control Program Of Waste Management Outer Loop Recycling And Disposal Facility, Louisville, Kentucky, Usa, Russell P. Defusco
Bird Strike Committee-USA/Canada Joint Annual Meeting: 9th (2007)
Landfills and airports have a long history of incompatibility. Birds are attracted to landfills for various reasons including food sources, habitat, and orographic lift. Since landfills can be avian attractants, they are required to be sited at least 10,000 feet away from commercial airports in the United States. Waste Management of Kentucky (WMK) operates a municipal landfill and recycling facility -- the Outer Loop Recycling and Disposal Facility (OLRDF) located less than 1.5 miles south of the Louisville Standiford airport which, as the hub airport for United Parcel Service, is the fourth largest cargo airport in the U.S. As part …

Management programs aimed at reducing wildlife damage to row crops rely on information concerning the spatial nature of wildlife damage at local and landscape scales. In this study we explored spatial patterns of wildlife damage within individual corn and soybean fields by describing relationships between specific locations where wildlife damage was recorded and distances from such locations to various habitat types that presumably influenced animal abundance and movements in our study area. Using stratified random sampling, we conducted depredation surveys of 100 corn fields and 60 soybean fields from May through October both in 2003 and 2004 and recorded the …

Daytime Cover, Diet And Space-Use Of Golden Jackals (Canis Aureus) In Agro-Ecosystems Of Bangladesh, Michael M. Jaeger, Emdadul Haque, Parvin Sultana, Richard L. Bruggers
United States Department of Agriculture Wildlife Services: Staff Publications
Golden jackals are locally common in Bangladesh despite intensive cultivation and high human densities. We studied the relative importance of seasonal flooding, rodent prey-base, and daytime cover on the occurrence of golden jackals in the two major agro-ecosystems in Bangladesh, one with annual monsoon flooding and the other without. Jackals were less common throughout the year where floodwaters occurred that would have excluded them for 1–3 months during their pup-rearing season. Diets of jackals were similar in the two agro-ecosystems. Rodents were the most common food type in scats throughout the year. The occurrence of burrowing rats in scats peaked …

Fisheries Research Report No. 163 - Spatial Scales Of Exploitation Among Populations Of Demersal Scalefish: Implications For Management. Part 1: Stock Status Of The Key Indicator Species For The Demersal Scalefish Fishery In The West Coast Bioregion., Department Of Fisheries, Western Australia
Fisheries Research Reports
Final FRDC report - Project 2003/052
The levels of exploitation on dhufish and pink snapper across the West Coast Bioregion and for baldchin groper at the Abrolhos Islands are above international benchmark standards. This indicates that these stocks are currently being overfished and are therefore likely to be being depleted to levels below those necessary to ensure their long-term sustainability. The current reliance of the dhufish catch on a single recruitment pulse together with the extremely truncated age distribution of pink snapper indicates that both these stocks are particularly vulnerable.
The West Coast Demersal Scalefish Fishery is a multi-species fishery …
