Status And Future Management Of Grey Goral (Naemorhedus Goral Bedfordi) In Pakistan, Fakhar -I- Abbas, Afsar Mian, Tanveer Akhtar, Thomas P. Rooney

Journal of Bioresource Management

Himalayan grey goral (HGG: Naemorhedus goral bedfordi) is endemic to Himalyas and regarded as Endangered/ Threatened. Study was designed to collect information on population biology, habitat, food and behaviour of population of HGG distributed in Pakistan, trying to understand its present status and conservational potentials. Our data suggest that the population, habitat and the species has sufficient potentials for its survival in the area, if protection from human predation is afforded to the species. HGG population is isolated into 7-8 subpopulations and is facing male-biased mortality, therefore is likely to face bottleneck effects and subsequent population crash ascribed to …

Divergent Responses Of Cryptic Invasive Watermilfoil To Treatment With Auxinic Herbicides In A Large Michigan Lake, Syndell R. Parks

Masters Theses

Invasive plants are a major concern for environmental managers. Cryptic invasive taxa present additional challenges because of their potential to respond differently to management efforts. Invasive Eurasian watermilfoil (Myriophyllum spicatum) and hybrid watermilfoil (Myriophyllum spicatum x Myriophyllum sibiricum) cannot be reliably distinguished based on morphological characters and are therefore cryptic taxa. Laboratory studies show that on average, hybrid watermilfoil grows faster, branches more, and is less responsive to standard control measures developed for Eurasian watermilfoil. These laboratory results predict less effective control of hybrid watermilfoil in mixed populations treated uniformly with one of these control measures. However, to date there …

Population Density Of The Florida Scrub Lizard (Sceloporus Woodi) In Managed Sand Pine Scrub And Longleaf Pine Sandhill Habitats, Matthew D. Kaunert, Lance D. Mcbrayer

Department of Biology Faculty Publications

Studies investigating managed landscapes are of increasing importance, as fragmentation is a known cause of biodiversity loss. From June to September 2012, we sampled populations of the rare, endemic Florida Scrub Lizard (Sceloporus woodi) across the Ocala National Forest (ONF) to compare lizard density across two managed habitat types. Florida Scrub habitat in the ONF is clearcut and roller-chopped, whereas Longleaf Pine habitat is managed via prescribed burning. We sampled 10 stands of Florida Scrub (2–3 y post disturbance) and 10 stands of Longleaf Pine (1 y post-disturbance) for lizards. We compared lizard density between the interior of …

Evaluation Of Harvest Indices For Monitoring Cougar Survival And Abundance, Michael L. Wolfe, Eric M. Gese, Patricia A. Terletzky, David C. Stoner, Lise M. Aubry

Wildland Resources Faculty Publications

Harvest indices are used by state wildlife management agencies to monitor population trends and set harvest quotas for furbearer species. Although harvest indices may be readily collected from hunters, the reliability of harvest indices for monitoring demography and abundance of the harvested species is rarely examined, particularly amongst large carnivores. The overall objective of this study was to assess whether cougar (Puma concolor) harvest statistics collected by wildlife managers were correlated with changes in cougar demography, mainly survival rates and abundance. We estimated key demographic parameters for 2 cougar populations in Utah over 17 years during which we …

Food Waste At Retail, Erin G. Killeen Davis

Graduate Theses and Dissertations

Food waste at retail represents forgone sales and embodies store management and disposal costs. Fresh produce is the largest contributing sector to food waste at retail and bulky, seasonal products are an added challenge when stores experience a high waste event. In order to improve, retailers need to better understand the costs of food waste, as well as how management strategies can impact these costs.

Using pumpkins as an example of bulky, seasonal products, a twofold research project was conducted to better understand contributors to, and costs of food waste at the retail level. In part one, using data from …

Water Column Productivity And Temperature Predict Coral Reef Regeneration Across The Indo-Pacific, Bernhard Riegl, Peter W. Glynn, Evie A. Wieters, Samuel J. Purkis, C. D'Angelo, Joerg Wiedenmann

Marine & Environmental Sciences Faculty Articles

Predicted increases in seawater temperatures accelerate coral reef decline due to mortality by heat-driven coral bleaching. Alteration of the natural nutrient environment of reef corals reduces tolerance of corals to heat and light stress and thus will exacerbate impacts of global warming on reefs. Still, many reefs demonstrate remarkable regeneration from past stress events. This paper investigates the effects of sea surface temperature (SST) and water column productivity on recovery of coral reefs. In 71 Indo-Pacific sites, coral cover changes over the past 1-3 decades correlated negative-exponentially with mean SST, chlorophyll a, and SST rise. At six monitoring sites …

Faculty members mindful of the ticking tenure and promotion clock seek ways to balance the competing and sometimes overwhelming demands of research, teaching, and service. One way to balance these demands is to find opportunities for collaboration with colleagues, especially in research. There are several compelling reasons to pursue joint research projects with colleagues; however, collaboration can be challenging. This article discusses the benefits and challenges of working on collaborative research projects with colleagues from the same discipline as well as across disciplines.

The Supply Chain Of Fair Trade Coffee: Challenges, Opportunities & The Future Inside A Troubled Industry, Katharine D. Lukas

Graduate College Dissertations and Theses

What started as a grassroots effort to aid tradespeople in developing nations, Fair Trade and similar certification models have, over the last sixty years, successfully established themselves as a viable alternative to conventional international trade; the ongoing growth of their market share and volume emphasize the increasing market demand for these alternatives. For coffee, Fair Trade's oldest and most established commodity, over two billion pounds was sold as certified in 2012 alone and the percentage of certified coffee continues to grow in share each year (Volcafe, 2012, Fair Trade USA 2012). As Fair Trade continues to grow, so does the …

Managing Hybridization Of A Recovering Endangered Species: The Red Wolf Canis Rufus As A Case Study, Eric M. Gese, Fred F. Knowlton, Jennifer R. Adams, Karen Beck, Todd K. Fuller, Dennis L. Murray, Todd D. Steury, Michael K. Stoskopf, Will T. Waddell, Lisette P. Waits

USDA Wildlife Services: Staff Publications

Hybridization presents a unique challenge for conservation biologists and managers. While hybridization is an important evolutionary process, hybridization is also a threat formany native species. The endangered species recovery effort for the red wolf Canis rufus is a classic system for understanding and addressing the challenges of hybridization. From 1987‒1993, 63 red wolves were released from captivity in eastern North Carolina, USA, to establish a free-ranging, non-essential experimental population. By 1999, managers recognized hybridization with invasive coyotes Canis latrans was the single greatest threat to successful recovery, and an adaptive management plan was adopted with innovative approaches for managing the …

Modeling The Cost Of Bird Strikes To Us Civil Aircraft, Aaron M. Anderson, David S. Carpenter, Michael J. Begier, Bradley F. Blackwell, Travis L. Devault, Stephanie A. Shwiff

USDA Wildlife Services: Staff Publications

The objective of our analysis is to develop a model of damage costs that arise from collisions between aircraft and birds, based on data drawn from the Federal Aviation Administration National Wildlife Strike Database (NWSD). We develop a two-part model, composed of two separate statistical models, that accounts for the effects of aircraft mass category, engine type, component of the aircraft struck, and the size and number of birds struck. Our results indicate the size of bird, number of birds, and engine ingestions are the largest determinants of strike-related costs. More generally, our result is a model that provides a …
