Until recently, the negative effects associated with the spread of large retail institutions away from the central business districts of local communities was most commonly identified with towns and cities in the developed ...

Differential resource use, habitat partitioning, and sexual segregation have been noted for many ungulate species. However, the mechanisms behind sexual segregation have not been resolved. This study was designed to examine ...

I investigated factors influencing diversity ami abundance of wintering raptor assemblages in southern Texas. I approached this problem from several spatial and temporal scales, ranging from continental to patch, and 30 ...

Rainfall, one of the most important hydrologic model inputs, varies spatially and temporally. Simulations using rainfall data with a reasonable representation of this variability can be expected to produce better results ...

Black bear habitat use based on available digestible energy was investigated in the Serranias del Burro, Coahuila, Mexico, during 1998-2001. Reproduction, survival and density of the bear population were also calculated ...

Molt intensity, digestive tract morphology, diet, and carcass composition of northern pintails were investigated along the southern Texas Coast during winters of 1997-98 and 1998-99. Precipitation was 133% and 83% of the ...

A full wave analysis of the electromagnetic field in the time-domain derived from R. P. Feynman’s path integral is examined. The propagator, which evolves the fields through successive time steps, comes from a state variable ...
