The Southeastern Fishes Council Technical Advisory Committee reviewed the diversity, distribution, and status of all native freshwater and diadromous fishes across 51 major drainage units of the southern United States. The southern United States supports more native fishes than any area of comparable size on the North American continent north of Mexico, but(More)
abStraCt: This is the third compilation of imperiled (i.e., endangered, threatened, vulnerable) plus extinct freshwater and diadromous fishes of North America prepared by the American Fisheries Society's Endangered Species Committee. Since the last revision in 1989, imperilment of inland fishes has increased substantially. This list includes 700 extant taxa(More)
Solifluction patterns on Lee Ridge, Glacier National Park, Montana, USA, were characterized through a combination of field transects, enhanced, digital aircraft data, and geostatistics. The objectives were to (i) assess the role of high spatial resolution digital imagery for mapping the areal extent and spatial pattern of solifluction steps and risers(More)
BACKGROUND Research on the potential effects of cognitive intervention in healthy elderly has been motivated by (1) the apparent effectiveness of cognitive rehabilitation in Alzheimer's disease (AD) patients; (2) the face validity of bolstering skills eventually burdened by disease; (3) interest in low-cost/noninvasive methods of preventing or delaying(More)
Background. Whether or not the familial form of papillary thyroid carcinoma is more aggressive than the sporadic form of the disease remains controversial. Methods. To explore this question and whether or not increased aggressiveness is more apparent in families with multiple affected members, we performed a chi square by trend analysis on our patients(More)
POLLUTION CONTROL CACHING The bandwidth mismatch of today's high speed processors and standard DRAMS is between a factor of 10 to 50. From 1995 to the year 2000 this mismatch is expected to grow to three orders of magnitude, necessitating greater emphasis for on-chip caches. However, the cost of on-chip memory is largely a function of the chip area it(More)
This paper examines the spatial arrangement of social and economic networks among villages in Nang Ž. Rong district, Thailand. We use spatial information from a geographic information system GIS for the Ž. district to help interpret the patterns of movement of agricultural equipment large tractors between villages, of people into villages for temporary(More)
Social and biophysical data were collected, integrated, and analyzed to examine scale-dependent relationships between selected population and environmental variables for a study site in northeast Thailand. Data sets were genemted through the. use of remote sensing to characterize land-use/land-cover and plant biomass variation across the Nang Rong district;(More)
