Intraspecific home range scaling: a case study from the owl limpet (Lottia gigantea)

Creator:: Fenberg, Phillip B.
Abstract:: Background: The owl limpet (Lottia gigantea) is an ectothermic invertebrate that inhabits the rocky intertidal zone where it territorially defends home ranges and grazes algae growing on the rocks. Among endothermic species, home range scales isometrically with body mass. Hypothesis: Home range area scales isometrically (scaling exponent ∼1.0) across individuals...

The Influence of fire on the Radiocarbon Signature and Character of Soil Organic Matter in the Siskiyou National Forest, Oregon, USA

Creator:: Heckman, Katherine, Campbell, John, Powers, Heath, Law, Beverly, and Swanston, Chris
Abstract:: Forest fires contribute a significant amount of CO₂ to the atmosphere each year, and CO₂ emissions from fires are likely to increase under projected conditions of global climate change. In addition to volatilizing aboveground biomass and litter layers, forest fires have a profound effect on belowground carbon (C) pools and...

Human hunting mortality threshold rules for extinction in mammals (and fish)

Creator:: Charnov, Eric L. and Zuo, Wenyun
Abstract:: Question: Are there general life-history rules for exploitation-caused extinction of mammal populations? Mathematical methods: A population of size N faced with the added mortality of human exploitation will deterministically go extinct if its per-capita birth rate can no longer match its per-capita mortality rate as N approaches zero. We develop...

Shrimp adjust their sex ratio to fluctuating age distributions

Creator:: Charnov, Eric L. and Hannah, Robert W.
Abstract:: Long-term data sets that quantitatively confirm basic ecological theory are rare for field populations. Highly variable recruitment often causes wide temporal variation in population age distribution and basic theory for adaptive sex ratio often predicts ‘sex ratio tracking’ to match the fluctuating age distribution. Using sex-changing shrimp as a model...

Non-forest Plant Communities of the Northern Oregon Coast Range and Vicinity Draft Report

Creator:: Glavich, Doug
Abstract:: DRAFT REPORT. In 2013 – 2015, reconnaissance observations were made across non-forest habitats on FS and BLM land in the Coast Range and Cascade foothills within the Salem and Eugene BLM district areas for plant communities that did not fit the USFS Northwest Oregon Non-forest Plant Community guide. Surveys were...

Black bear population ecology

Creator:: Lindzey, Frederick Grier
Abstract:: Despite relatively mild weather, black bears (Ursus americanus) in southwestern Washington entered dens and remained for an average of 126 days. Bears entered their dens during a 5-week period which began on 21 October. A significant difference (P < 0.05) was found among the average dates of den entrance of...
