The impacts of modern limited-access highways on the spatial distribution of non-agricultural development, and their influence in the shaping of occupancy patterns, are far-reaching and should be of eminent concern to all Americans. The location of the Interstate routes, with 80 percent of their 41,000 miles crossing rural localities, renders...
The present study was designed to examine the relationship
between expressed attitudes toward child-rearing, and children's
social behavior in a preschool setting. More specifically, the study
was concerned with the association of parental authoritarian, hostile-rejecting,
and democratic attitudes with the aggressive and cooperative
peer interactions of preschool children. Under investigation...
Increased competition in the market place for both occasional and professional chain saw users has led to a desire for improved performance in chain saw guide bars. One aspect of improved performance is lower bar weight. The primary focus of this research was to establish the feasibility of a lower...
Timber harvesting in the Pacific Northwest (PNW) region of the United States of America (USA) has a long history of explosive growth, environmental litigation and regulation, economic downturn, and workforce dynamics that have created a current environment where cable-assisted harvesting is quickly gaining popularity among private and public land managers...
Understanding the drivers of species occurrence is a fundamental goal in basic and applied ecology. Occupancy models have emerged as a popular approach for inferring species occurrence because they account for problems associated with imperfect detection in field surveys. Current models, however, are limited because they assume covariates are independent...
The influence of media size upon the effective removal
of organic waste from a liquid substrate was studied by the
use of three experimental trickling filters under a set
of uniform operating conditions. The range of experiments
involved hydraulic loadings of increasing magnitude and
of constant organic strength.
The trickling...
I examined the avian biogeography of the islands of Lago Gatun, Panama, in an effort to better understand the effects of forest fragmentation in this biodiverse region, and specifically to understand the importance of fragment isolation and the mechanism behind its effects on tropical bird distribution. I combined exhaustive surveys...
