Estimates of soil ingestion by wildlife Estimates of soil ingestion by wildlife

Many wildlife species ingest soil while feeding, but ingestion rates are known for only a few species. Knowing ingestion rates may be important for studies of environmental contaminants. Wildlife may ingest soil deliberately, or incidentally, when they ingest soil-laden forage or animals that contain soil. We fed white-footed mice (Peromyscus leucopus) diets containing 0-15% soil to...

Conservation of invertebrates in US National Parks Conservation of invertebrates in US National Parks

Entomologists who enter national parks often are surprised by the diversity of life and geography found in these remarkable natural areas. There are ichneumon wasps, carabid beetles, leps…and, of course, there are trees and mountains. In contrast, an average person entering the same parks will see the magnificent mountains and rivers, the endless forests and meadows, and the abundant...

Habitat use by an endangered riverine fish and implications for species protection Habitat use by an endangered riverine fish and implications for species protection

We investigated habitat specificity of the amber darter (Percina antesella Williams & Etnier 1977), an imperiled fish from restricted portions of 2 rivers in the southeastern United States. Foraging amber darters occupied a narrow range of riffle habitat, consistently avoiding areas 20 cm deep and with velocity 10 cm. s−1 near the substrate, occupying areas with cobble or gravel...

In my experience: Improved capture techniques for psittacines In my experience: Improved capture techniques for psittacines

Four methods for capturing psittacines were developed and tested in Puerto Rico from 1991-1993. Elevated mist nets at canopy height in scrub-forest or mangrove habitat captured fewer nontarget birds and possibly more parakeets than mist nets at ground level. Playback of conspecific calls may have attracted parakeets to the net area and reduced the need to erect more than six 12-m long...
