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)
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 ge-ometries, or meshes. These meshes " know " little about(More)
Toxoplasma gondii is an important protozoan parasite of mammals that impacts animal health and behavior. Although this parasite has been documented in several cervid species, including red deer (Cervus elaphus) in Europe, little is known about T. gondii impacts on the closely related North American counterpart, the elk (wapiti, Cervus canadensis), which has(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)
In peninsular Florida, USA, the palm-feeding guild is dominated by the black bear (Ursus americanus floridanus, Pallas) and the giant palm weevil (Rhynchophorus cruentatus, Fabricius). Bears damage palms by consuming their hearts, allowing the weevil to reproduce within the exposed palm tissue. The giant palm weevil reproductively benefits from bear-damaged(More)
