The Bering Sea is a highly productive ecosystem with abundant prey populations in the summer that support some of the largest seabird colonies in the Northern Hemisphere. In the fall, the Bering Sea is used by large numbers of migrants and post-breeding seabirds. We used over 22000 km of vessel-based...

Mensacarcin is a stereogenic complex polyketide with potent anti-tumor activity produced by a soil-dwelling Streptomyces bottropensis. The US National Cancer Institute (NCI) 60 human tumor cell line anticancer drug screen (NCI-60) reveals mensacarcin’s cytostatic properties in almost all tested cell lines and distinct cytotoxic properties specifically in eight melanoma cell...
Animal pollination is critical to plant reproduction in agricultural and wildland ecosystems. Much of the production of seeds and fruits in natural areas, which underlie many food webs, depends on pollination services by insects. The taxon responsible for delivering the bulk of these services in most temperate systems is bees....
Native bees play an important role as pollinators of natural vegetation and agricultural
crops. Yet many pollinators, including some native bees, are declining in numbers.
Some of the potential causes of these declines are habitat destruction and degradation
by various human land uses, including urban development and sprawl, construction of...
Individuals participating in the enviromental sport activity courses of backpacking-orienteering, mountaineering, and scuba diving responded to pre- and post - test trials of the Self-Cathexis Scale ard the Body-Oathexis Scale. Two control groups composed of random samples of the university student population reponded to the Self-Cathexis Scale Body-Cathexis Scale: one...
In a story of his life Les reflects on what he
has gained and what he has lost while seeking success in
the moving and shifting of military and academic life
through homes and schools all over the United States.
He describes himself as between races, languages, and
cultures.
Human satiety and hunger are usually measured by observations of
eating behavior or by verbal reports. Neither of these seems to be an
objective method of measurement. Some studies have indicated that pupil
responses to pictures of food may correspond with interest in food. The
objective of this study was...
