Kinzua Dam: a Study in the Congressional Disruption, Relocation-Resettlement, and Rehabilitation of the Seneca Nation of Indians

Verelst, Robert 01 1900 (has links)
This thesis embraces four major topics coinciding with the four considerations designated in President John F. Kennedy's letter to President Basil Williams of the Seneca Nation and the reactions to those items generated during numerous hearings of the House Subcommittee on Indian Affairs. The four topics covered in the President's letter include the possibility of acquiring adjacent property, commonly referred to as "in lieu of" lands, to replace the Indian real estate taken for the Allegheny Reservoir; a review of the reservoir's recreational potential for the benefit of the Seneca Nation; special damages accruing to the Senecas for the loss of their land; and relocation and resettlement.

Opposing deer and caterpillar foraging preferences may prevent reductions in songbird prey biomass in historically overbrowsed forests

Godfrey, R. Keating, Yerger, Ellen H., Nuttle, Timothy J. 01 1900 (has links)
Overbrowsing by ungulates decimates plant populations and reduces diversity in a variety of ecosystems, but the mechanisms by which changes to plant community composition influence other trophic levels are poorly understood. In addition to removal of avian nesting habitat, browsing is hypothesized to reduce bird density and diversity through reduction of insect prey on browse-tolerant hosts left behind by deer. In this study, we excluded birds from branches of six tree species to quantify differences in songbird prey removal across trees that vary in deer browse preference. Early in the breeding season, birds preyed on caterpillars at levels proportional to their abundance on each host. Combining these data with tree species composition data from stands exposed to experimentally controlled deer densities over 30 years ago, we tested whether overbrowsing by white-tailed deer reduces prey biomass long after deer densities are reduced. Our analysis predicts total prey availability in the canopy of regenerating forests is fairly robust to historic exposure to high deer densities, though distribution of prey available from host species changes dramatically. This predicted compensatory effect was unexpected and is driven by high prey abundance on a single host tree species avoided by browsing deer, Prunus serotina. Thus, while we confirm that prey abundance on host trees can act as a reliable predictor for relative prey availability, this study shows that quantifying prey abundance across host trees is essential to understanding how changes in tree species composition interact with ungulate browse preference to determine prey availability for songbirds.
