Rumen Microbial Ecology in Mule Deer [PDF]
Mule deer rumen microbial populations from animals in the natural habitat in Utah and from captive deer fed various rations were studied. The microorganisms were characterized on the basis of morphology and Gram reaction. Rumen samples contained 13 identifiable types of bacteria and one genus of ciliate protozoa

Mule deer (Odocoileus hemionus) resource selection: trade-offs between forage and predation risk
Ungulates commonly select habitat with higher forage biomass and or nutritional quality to improve body condition and fitness. However, predation risk can alter ungulate habitat selection and foraging behavior and may affect their nutritional condition ...

Cyclic Variation in the Mule Deer Thymus.
SummaryThymus glands from a series of fawn, yearling, and adult female mule deer, collected on the National Bison Range, Moiese, Mont., varied in volume with the season. The thymus reached its lowest volume during the winter months (Dec.-Feb.)

Polarized microscopic images of the outer bone cortex (a and b) and deeper trabecular bone (c and d) of the deer calcaneus in thin cross‐sections. The brighter gray levels reflect more oblique‐to‐transverse collagen fibers in the compression/dorsal bone (a, c) and the darker gray levels reflect more longitudinal collagen in the tension/plantar bone (b,

Developing a macroecology for human‐altered ecosystems
Although anthropogenically‐induced ecological disruptions are fundamentally important in defining ecosystem properties, they are largely overlooked by macroecological theory. Anthropogenic disruptions and their effects are generally not comparable to one another, nor to disturbances that are part of natural disturbance regimes.

Diets of Desert Mule Deer [PDF]
We studied the diets of desert mule deer (Odocoileus hemionus crooki Mearns) at 3 sites in Arizona and collated this information with that of previous diet studies of desert mule deer across their range in the United States. We documented 96 browse, 69 forbs, 14 succulent, and 6 grass species that each constituted greater than or equal to 1% of the ...

When wolves aren't enough: revisiting trophic cascades in northern Wisconsin
Elimination of top predators has allowed large herbivores to flourish in many terrestrial ecosystems, transforming food webs and ecosystem functions. Restoration of large predator communities is hoped to reverse negative effects of this trophic downgrading, but evidence for such effects is elusive.

Abstract The return of grey wolves to multi‐use landscapes in North America and Europe raises concerns over accompanying risks of livestock predation. While local‐level risk factors have received attention, it is difficult to explore the role that landscape‐scale variables, such as landscape connectivity, play in driving livestock losses.

Capacity and limitations of US wild meat donation programmes
Abstract Historically, sharing of wild harvests to facilitate food security followed concepts of kin selection and reciprocal altruism. However, cultural shifts have reduced access to foods for some populations in modern times. Cultural altruism through sustainably harvested wild meat donation programmes (WDPs) can reduce food and nutritional ...
