Grazing Impacts of Diverse Zooplankton Taxa on Thin Layers
The US Navy needs to know how distributions and abundances of light-scattering and sound-scattering organisms in the ocean vary in space and time, particularly in the vertical dimension. Recent field observations have shown that many biological properties may vary substantially over small (e.g. centimeter) scales, commonly referred to as “thin layers” (e.g. Cowles et al. 1998, 1999, Hanson & Do...

متن کاملSpecies-specific impacts of collembola grazing on fungal foraging ecology
Fungi are primary agents of organic matter decomposition in forests. Although invertebrate grazing affects fungal biomass and morphology, the species-specific consequences of these interactions are little understood. Using three collembola species (Folsomia candida, Protaphorura armata, Proisotoma minuta) we employed a multi-trophic approach to investigate the individual effects of invertebrate...
متن کاملWater Quality Conditions Associated with Cattle Grazing and Recreation on National Forest Lands
There is substantial concern that microbial and nutrient pollution by cattle on public lands degrades water quality, threatening human and ecological health. Given the importance of clean water on multiple-use landscapes, additional research is required to document and examine potential water quality issues across common resource use activities. During the 2011 grazing-recreation season, we con...
