The major historical studies that have examined American
biology have emphasized the development of experimental biology at
the end of the nineteenth century. In this characterization, the
descriptive branch of biology has often been treated as less than
important and, in several cases, as a hindrance in the application
of...
Background: Barn Swallows (Hirundo rustica) breed almost exclusively in the Northern Hemisphere. However, since the early 1980's, a small disjunct breeding population has become established in eastern Argentina, presumably by birds previously derived from those breeding in North America. Currently, it is unknown where these individuals go following breeding and...
The objectives of this study were to determine the
peritoneal clearance of vitamin B-6 and to evaluate the
vitamin B-6 and vitamin A status of children with chronic
renal failure undergoing continuous ambulatory peritoneal
dialysis (CAPD). Eight children aged 2 to 18 years
(mean 12) were included in the study....
As time continues, the issue of full European Union membership for Norway becomes a more pertinent issue. The EU has long awaited the membership of Norway, but unfortunately the Nordic country has decided to remain independent. Norway’s historical past has led many Norwegians to believe their country is not ready...
Small mammal populations are vital to the Metolius Forest Preserve. The forest preserve is undergoing selective thinning, which may affect small mammal populations in the forest. Our null hypothesis is that small mammal populations are not affected by the treatment of the forest. In addition to the null hypothesis, we...
INTRODUCTION: Many species of ambystomatid salamanders are dependent upon highly variable temporary wetlands
for larval development. High larval densities may prompt the expression of a distinct head morphology that may
facilitate cannibalism. However, few studies have characterized structural cannibalism within natural populations of
larval salamanders. In this study we used...
Shepody potatoes were grown under sprinkler irrigation on sloping ground (4.2 to 8.5 percent slope) with and without mechanically applied wheat straw, grass straw, or reservoir tillage. Mechanical furrow mulching used 1,000 lbs/ac of wheat straw or grass straw. Mulched, non-mulched, reservoir-tillage, and check plots were irrigated 12 times with...
Variation in growth rate of Dover sole (Microstomous pacificus) off Astoria and Brookings, and English sole (Parophrys vetulus) growth off Astoria and Coos Bay, Oregon was studied using the distance between annuli on scales and interoperculum bones indicating growth rate for Dover sole
and English sole respectively. The age at...
The objectives of this research paper are (1) to establish if a
relationship exists between those water-related services - domestic
water and waste disposal - already present in the North Albany are a
prior to 1966 and housing growth that occurred during the period
1966-1975, (2) to assess the impact...
