Effects of spatial grouping on the functional response of predators
A unified mechanistic approach is given for the derivation of various forms of functional response in predator-prey models. The derivation is based on the principle-of-mass action but with the crucial refinement that the nature of the spatial distribution of predators and/or opportunities for predation are taken into account in an implicit way. If the predators are assumed to have a homogeneous sp

Suggestions for new and aspiring graduate students in wildlife science
The transition from an undergraduate to a graduate program can be a difficult experience for students. Many undergraduates are unfamiliar with the process of preparing for graduate school, especially the search for a graduate program. Once in graduate school, they may be unfamiliar with requirements (both written and unwritten) and expectations, and they may also lack the necessary knowledge or s

Effects of vertebrate herbivores on soil processes, plant biomass, litter accumulation and soil elevation changes in a coastal marsh
1 Submergence of coastal wetlands in Louisiana is currently rapid and widespread. A number of factors contribute to this loss of habitat, including the activities of herbivores. The objective of this study was to examine the effects of large mammals, predominantly nutria and wild boar, on processes controlling soil elevation in coastal marshes.2 Effects of herbivores on soil and vegetation were as

Factors influencing cattail abundance in the northern Everglades
Since the early 1900s, the Everglades have been influenced by anthropogenic actions including altered hydrology and increased nutrient loading. In the northern Everglades an apparent effect of these disturbances has been the development and proliferation of dense cattail (Typha spp. ) stands in areas previously dominated by sawgrass (Cladium jamaicense Crantz) and sloughs. Cattail cover, soil nutr

Resource management of forested wetlands: Hurricane impact and recovery mapped by combining Landsat TM and NOAA AVHRR data
A temporal suite of NOAA Advanced Very High Resolution Radiometer (AVHRR) images, transformed into a vegetation biomass indicator, was combined with a single-date classification of Landsat Thematic Mapper (TM) to map the association between forest type and hurricane effects. Hurricane effects to the forested wetland included an abrupt decrease and subsequent increase in biomass. The decrease was a
