Introduced Species And The Issue Of Animal Welfare, Michael Hutchins, Victoria Stevens, Natasha Atkins

Ecology Collection

Recently, considerable debate has been heard about the control or elimination of introduced or "exotic" animals on publicly held U.S. lands. Species introductions, whether intentional or unintentional, seem to be an inevitable result of human activities, but they may result in both economic and ecological problems: It has been estimated that over 90 percent of all such introductions have been harmful in some respect. Control of exotics can be accomplished through containment, shooting, poisoning, reintroduction of native predators, introduction of disease organisms, live capture and removal, and reproductive inhibition.

Those who must make decisions about the fate of introduced species …

Experiences In The Protection Of The Large Predators In Finland, Erkki Pulliainen

Ecology Collection

During the nineteenth century, the large predators of Finland- wolf, bear, lynx, and wolverine- were exterminated in the southern and western regions of the country. There were almost no lynx by the late 1950s, but a protection order issued in 1968 has resulted in a steady increase in their number, to about 300 by 1980. There was a breeding population of wolverines until the late 1960s, but in the 1970s, most were killed by snowmobiles, and only 10-30 are now thought to inhabit the frontiers between Finland and the USSR, and Finland and Norway. Bears, in the 1970s, tended to …

Soil Traversing Arthropod Populations As Sampled By Pitfall Traps In Sunflower And Three Adjacent Habitats In Northeast Arkansas, Linda A. Lee, Harvey E. Barton

Journal of the Arkansas Academy of Science

Soil traversing arthropod populations were sampled by pitfall traps in sunflower (Helianthus spp.) and three adjacent habitats during the months of July, August and September of 1980 and May, June, July and August of 1981. In1980, four varieties of sunflower (Ellar, Hybrid 670, 891 and S-345) were planted. A single variety of sunflower (Ellar) was planted in1981. The three adjacent habitats in both 1980 and 1981 were a pine stand, grass border and fence row. Of 1,748 specimens collected in 1980, 17 orders and 48 families were represented. Four orders comprised 78% of the total catch: Hymenoptera (45%), Acari (17%), …

Endemic Flora And Fauna Of Arkansas, Henry W. Robison, Kenneth L. Smith

Journal of the Arkansas Academy of Science

Arkansas has an amazing diversity of plants and animals contained within its political boundaries. Forty-seven taxa are reported as Arkansas endemics, including seven plants, thirteen crustaceans (two amphipods, three isopods, eight crayfishes), nine insects (one mayfly, one caddisfly, three stoneflies, four beetles), ten snails, six fishes, and two salamanders.

The Red-Tailed Hawk On Sauvie Island, Oregon, Kevin J. Lien

Dissertations and Theses

A study was undertaken to determine the abundance, distribution, perching heights, diets and territory sizes of Red-Tailed Hawks on Sauvie Island, Oregon. Sauvie Island supported a large wintering population of non-territorial Red-Tailed Hawks. The establishment of territories began around 10 January. Average perch height was found to be 14.2 m. Average perch height increased from fall to spring, corresponding-to the onset of the breeding season and to the onset of egg-laying and incubation. Voles (Microtus spp.) were the principal prey year-round, though waterfowl were more important in terms of biomass in the winter and early spring. Territory sizes on the …

The Multi-Individual Cremation Phenomenon Of The Santa Cruz Drainage, Karl J. Reinhard, T Michael Fink

Karl Reinhard Publications

Multi-individual cremation deposits found in the upper Santa Cruz River drainage were previously interpreted as the result of hypothesized cultural contact in the area. A review of 50 cremation deposits for which detailed analyses are available indicates that mulii-individual cremation deposits are the result of incomplete gleaning practices and have doubtful cultural significance. Hypotheses are generated from the present data which account for the apparent variation in cremation practices within the study area.
