Wildlife Habitat on Grazed or Ungrazed Small Pond Shorelines in South Texas

South Texas Climate 2100: Potential Ecological and Wildlife Impacts

In South Texas, the impacts of increased temperature and atmospheric carbon dioxide (CO 2) on the ecological relationships that provide the foundations for wildlife habitats and populations are potentially huge, but largely unknown at present. This is because little research attention has been paid to this issue, which is unfortunate because wildlife are culturally and economically important in...

I check this assertion by analyzing wages and status within the firm, with status measured as the worker rank in the firm wage hierarchy. More precisely, I focus on worker mobility bet...

Bird Communities in Grazed and Ungrazed Oak-Pine Woodlands at the San Joaquin Experimental Range1

Ten years of spot-mapping censuses in grazed and ungrazed plots at the San Joaquin Experimental Range, Madera Co., California, indicate likely changes in abundance of several bird species. Data do not, however, indicate that any species is in jeopardy as a result of grazing in the foothill woodlands. Brown-headed cowbirds are probably more abundant in the woodlands with cattle than without catt...

Changes in vegetation states in grazed and ungrazed Mackenzie Basin grasslands, New Zealand, 1990–2000

Changes in vegetation from 1990 to 2000 were examined at 10 high country localities, representing four grassland types: fescue tussock (Festuca novae-zelandiae), snow tussock (Chionochloa rigida), red tussock (C. rubra), and silver tussock (Poa cita). At each locality, three treatments were established: ambient sheep+rabbit grazing, rabbit grazing only, and no grazing. The mutivariate methods o...
