Although studies of species linked by a common resource (i.e. ecological guilds) have so far mainly focused on competition and predation, guilds are also good places to find mutualism. In this review we consider some three- and four-species community modules to illustrate examples of wide relevance. Mutualism arises from various direct and indirect trophic(More)
Concerns over migratory bison (Bison bison) at Yellowstone National Park transmitting brucellosis (Brucella abortus) to cattle herds on adjacent lands led to proposals for bison vaccination. We developed an individual-based model to evaluate how brucellosis infection might respond under alternate vaccination strategies, including: (1) vaccination of female(More)
The seasonal availability of food resources is an important factor shaping the life-history strategies of organisms. During times of nutritional restriction, physiological trade-offs can induce periods of immune suppression, thereby increasing susceptibility to infectious disease. Our goal was to provide a conceptual framework describing how the endemic(More)

Meningeal worm (Parelaphostrongylus tenuis) has been implicated in the failure of several elk (Cervus elaphus) restoration attempts in the eastern United States. However, limited post-release monitoring and a paucity of published literature prevents a clear understanding of this parasite's role in past failures. During winters of 1997-2001, the Kentucky(More)
This paper &velops a new method for associating geometxic models, and the operations used to construct them, with the formulation of continuum field equations. Current methods of engineering analysis link a geometric model to the continuum equatioos of a corresponding analysis model via intermediate geometries, or meshes. These meshes “know” little about(More)
Increasingly, wildlife managers and land managers are challenged to maintain the viability of large mammal populations. Although the moose (Alces alces) is an ecologically, economically, and culturally important ungulate species found throughout most of Sweden, little is known about its ecology throughout the southern part of the country. We collected(More)
' ALBANY. Nov. 9—Leave it to the Sullivans to do things in a big way. There are four Sullivans on the board of directors of the Civil S e r v i c e Employees Association. And when somebody calls for •-Bill" Sullivan, two of them respond. William A, Sullivan represents the Department of Audit and Control; William F. Sullivan represents the Judiciary. On the(More)
