Species richness and abundance of forest floor bryophytes, including epiphytes from incorporated litterfall, were assessed at two sites in western Oregon. Bryophyte diversity, abundance, and community composition were compared between sites, and between young forest stands ([approximately] 55 yrs.) and old-growth stands (400+ yrs.) within each site. Relationships of stand...

AN ABSTRACT OF THE THESIS OF
Thomas Roy Rambo for the degree of
Two measured sections of the upper Silurian Douro
Formation from Devon Island, N.W.T. were examined for their
faunal content with emphasis on the paleoecology and taxonomy
of the fauna. Atrypella is believed to have lived with
its beaks embedded in the muddy substrate of a somewhat
restricted environment. Intermittent, low...

1. Chronic infections may have negative impacts on wildlife populations, yet their effects are difficult to detect in the absence of long-term population monitoring. Brucella abortus, the bacteria responsible for bovine brucellosis, causes chronic infections and abortions in wild and domestic ungulates, but its impact on population dynamics is not...

Acquisition of divergent-productive thinking skills by using
elementary science materials constitutes the basic idea of this experiment.
The data collected was used to determine statistically if
the materials had a significant role in inducing such skills.
The Ss were fifth-grade students obtained from two public elementary
schools in Oregon. Those...

AN ABSTRACT OF THE THESIS OF
JOHN PAUL HUNTSBERGER for the
Archaeological investigations at the Cooper's Ferry site in Western Idaho have recovered cultural remains dating to 16,000 years ago, suggesting the oldest human occupation recorded in North America. However, many archaeologists have argued the initial peopling of North America occurred no earlier than the opening of an ice-free corridor between...
Although early adversity has been linked to worse mental and physical health in adulthood, few studies have investigated the pathways through which positive and negative dimensions of early experiences can jointly influence psychological well-being in later life. This study examined: (a) profiles of early experiences across multiple domains, (b) the...
