A Gis-Based Habitat Model Predicting Elk Nutritional Condition in the Pacific Northwest
… are unknown. Nutrition and summer-autumn body condition (percent body fat) have been linked to virtually every aspect of successful ungulate reproduction and productivity; however, many existing habitat evaluations discount the role of nutrition and are unlikely to detect changes in habitat …

Winter Diet and Nutritional Condition of White-Tailed Deer in the Northern Black Hills, South Dakota
… in January 1992 to evaluate the physical and nutritional condition of white-tailed deer inhabiting five NBH winter subranges. Habitat variables were measured at 100 random locations on each study area. Pellet groups were collected throughout each study area at two-week intervals during …

Terrestrial Salamanders in southern Appalachain Harwood Forests: Relative Abundance, Nutritional Condition, and Response to Silvicultural Practices
We compared techniques for assessing nutritional condition in 3 groups of terrestrial salamanders. We measured variability in species richness and relative abundance before harvest at 5 sites in the Jefferson National Forest of southwest Virginia and compared the effects of 7 silvicultural …

Nutritional Condition of White-Tailed Deer in the Central Black Hills, South Dakota: Influence of Habitat and Elk Competition
… begun in May 1994 to determine the physical and nutritional condition of white-tailed deer occupying five winter study areas, and on summer and winter ranges. Habitat variables, deer diet composition and quality, and nutritional condition were compared between the northern Black H ills (NB H) and …

Nutritional condition and stress response of fishes along a gradient of habitat quality in the St. Lawrence River: physiological consequences of anthropogenic habitat degradation
… underlying variation in organismal health and condition, such individual-level metrics are rarely evaluated in the context of ecosystem disturbance. Using physiological sampling, we can examine the effects of land use on the health of resident fishes, and improve our understanding of the …

Life history trade-offs in a parental care-providing fish: the role of reproductive value, predation threat, and physiological condition on brood abandonment decisions by paternal largemouth bass
… success at a cost to physiological and nutritional condition of the care-providing individual, and at a cost to future reproductive potential. Parental investment decisions are rooted in tradeoffs between these factors, and when the cost of care-provision is outweighed by potential …

Effects of Fire on the Nutritional Ecology of Selected Ungulates in the Southern Black Hills, South Dakota
… in the southern Black Hills. To ascertain the nutritional condition of white-tailed deer and mule deer (O. hemionus) and their response to fire, 5 adult white-tailed deer and 5 adult mule deer were collected in burned and unburned habitat, in February and August, 2002 and 2003. Collected deer …

Development of Lure Forages for Minimizing Winter Depredation By Deer in South Dakota
… little is known about their growth rates or nutritional requirements and characteristics during severe winters. The objectives for this study were: 1) To document and compare growth rates of fawns from eastern South Dakota and the Black Hills; 2) To develop/evaluate feeds (lure forages) for …

Estimation of Predator Densities in Western South Dakota
… and determine those best suited to local conditions. Knowledge of predator populations allow wildlife managers to prescribe and assess management and control activities. Objectives of this study were to assess the use of relative density estimation techniques for coyote (Canis latrans), …

Effects of enhanced winter nutrition and climatic variation on population performance of a large herbivore
… whereas recruitment of young is more variable. Nutritional condition and climate have the potential to influence demographic parameters that affect population growth. We focused on evaluating the effects of enhanced winter nutrition and environmental factors on survival of adult female and …

Investigations of the Trophic Relationships, Feeding Ecology and Feeding Behavior of Larval Spot, <i>Leiostomus Xanthurus</i> Lacepede, and Atlantic Croaker, <i>Micropogonias Undulatus</i> (Linnaeus) (Pisces:Sciaenidae)
… undulatus) larvae was evaluated and compared. Nutritional condition of spot larvae from the Gulf of Mexico was high, with no larvae classified as starving. This was probably due to an inability to sample starving larvae at sea because of predation pressure or was indicative of favorable feeding …

The Ecological Ramifications of Disease and Density in the Caribbean Spiny Lobster, <i>Panulirus argus</i>
… effect on population dynamics such as nutritional condition and short-term residency, likely due to their normal gregariousness. Thus, juvenile spiny lobsters appear to have developed remarkable contradictory behaviors, avoidance of infected conspecifics and gregariousness, both of …

Impacts of hypoxia on largemouth bass (Micropterus salmoides) behavior, physiology, and acclimation potential
… these areas altogether, 2) the physiological and nutritional condition of largemouth bass from the study site was similar to reference sites, indicating a lack of chronic stress or limited access to food, and 3) the physiological response of the study site fish to a low oxygen shock of 2.0 mg/L …

An assessment of the nutritional status and habitat quality of a southwestern Virginia deer herd
… Counties, Virginia, the relative abundance and nutritional status of the deer herd and the habitat quality of the HK area were studied relative to a deer herd and an area in the Stony Creek (SC) section of Giles County, Virginia, known to produce deer of good physical size and antler development …
