Studying the ecology of endangered species in portions of their range where the population remains abundant can
provide fundamental information for conservation planners. We studied nesting by radio-tagged Marbled Murrelets
(Brachyramphus marmoratus) during 2007 and 2008 in Port Snettisham, a relatively pristine, remote mainland fjord in
southeast Alaska with high...
Lead (Pb) is a metabolic poison that can negatively influence biological processes, leading to illness and mortality
across a large spectrum of North American avifauna (>120 species) and other organisms. Pb poisoning can result from
numerous sources, including ingestion of bullet fragments and shot pellets left in animal carcasses, spent...
Since the 1964 earthquake and geologic uplift, beavers (Castor canadensis) have expanded their historic range from the inland (outwash plain) Copper River Delta, Alaska to the once tidally influenced areas of the outer area (uplifted marsh). The uplift presents a unique opportunity to observe beaver expansion, habitat selection and influence...
Here, we describe and demonstrate a geographic information systems-based lithic morphometric research (GLiMR) software approach. GLiMR accurately and rapidly handles a sequence of ArcGIS procedures to extract geometric morphometric data from 2D and 3D scan files of lithic artifacts. GLiMR generates three main types of geometric properties: shape data, topographic...

Evaluating the success or failure of work force training programs is most often accomplished through the reporting of "objective" data. Rarely are the students' views of their own success in such a training program formally solicited or applied in any useful way. But participant perceptions can be a critical barometer...
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...
Excavation of pit feature 110 (F110) at the Cooper’s Ferry site (10IH73) in central Idaho provides a unique snapshot of the domestic lifeways associated with the Western Stemmed Tradition (WST). Analysis was conducted of the F110 assemblage to better understand the function F110 served. The contents of F110 include Canis...
