Long and Short-Term Effects of Fire on Soil Charcoal of a Conifer Forest in Southwest Oregon

Creator:: Pingree, Melissa R. A., Homann, Peter S., Morrissette, Brett, and Darbyshire, Robyn
Abstract:: In 2002, the Biscuit Wildfire burned a portion of the previously established, replicated conifer unthinned and thinned experimental units of the Siskiyou Long-Term Ecosystem Productivity (LTEP) experiment, southwest Oregon. Charcoal C in pre and post-fire O horizon and mineral soil was quantified by physical separation and a peroxide-acid digestion method....

Sex-biased dispersal in a rare butterfly and the implications for its conservation

Creator:: Bennett, Victoria J., Pack, Shalynn M., Smith, Winston P., and Betts, Matthew G.
Abstract:: The survival of many species may be dependent on their ability to exist in human-altered landscapes within metapopulations; in turn, metapopulation persistence is dictated by the ability of individuals to move effectively among patches to promote recolonization. The Taylor’s checkerspot butterfly (Euphydryas editha taylori) is a species that does not...

Impacts of disturbance on the terrestrial carbon budget of North America

Creator:: Kasischke, Eric S., Amiro, Brian D., Barger, Nichole N., French, Nancy H. F., Goetz, Scott J., Grosse, Guido, Harmon, Mark E., Hicke, Jeffrey A., Liu, Shuguang, and Masek, Jeffrey G.
Abstract:: Because it is an important regulator of terrestrial carbon cycling in North America, extensive research on natural and human disturbances has been carried out as part of the North American Carbon Program and the CarboNA project. A synthesis of various components of this research was carried out, and the results...

Post-fire tree establishment and early cohort development in conifer forests of the western Cascades of Oregon, USA

Creator:: Tepley, Alan J., Swanson, Frederick J., and Spies, Thomas A.
Abstract:: Early‐seral ecosystems make important contributions to regional biodiversity by supporting high abundance and diversity of many plant and animal species that are otherwise rare or absent from closed‐canopy forests. Therefore, the period of post‐fire tree establishment is a key stage in forest stand and ecosystem development that can be viewed...

Regional variation in stand structure and development in forests of Oregon, Washington, and inland Northern California

Creator:: Reilly, Matthew J. and Spies, Thomas A.
Abstract:: Despite its importance to biodiversity and ecosystem function, patterns and drivers of regional scale variation in forest structure and development are poorly understood. We characterize structural variation, create a hierarchical classification of forest structure, and develop an empirically based framework for conceptualizing structural development from 11,091 plots across 25 million...

Wolves and the Ecology of Fear: Can Predation Risk Structure Ecosystems?

Creator:: Ripple, William J. and Beschta, Robert L.
Abstract:: We investigated how large carnivores, herbivores, and plants may be linked to the maintenance of native species biodiversity through trophic cascades. The extirpation of wolves (Canis lupus) from Yellowstone National Park in the mid-1920s and their reintroduction in 1995 provided the opportunity to examine the cascading effects of carnivore–herbivore interactions...

Wildlife Encounters by Lewis and Clark: A Spatial Analysis of Interactions between Native Americans and Wildlife

Creator:: Laliberte, Andrea S. and Ripple, William J.
Abstract:: The Lewis and Clark journals contain some of the earliest and most detailed written descriptions of a large part of the United States before Euro-American settlement.We used the journal entries to assess the influence of humans on wildlife distribution and abundance. Areas with denser human population, such as the Columbia...

The enigmatic truffle Fevansia aurantiaca is an ectomycorrhizal member of the Albatrellus lineage

Creator:: Smith, Matthew E., Schell, Karlee J., Castellano, Michael A., Trappe, Matthew J., and Trappe, James M.
Abstract:: Fevansia aurantiaca is an orange-colored truffle that has been collected infrequently in the Pacific Northwest of the USA. This sequestrate, hypogeous fungus was originally thought to be related to the genera Rhizopogon or Alpova in the Boletales, but the large, inflated cells in the trama and the very pale spore...

Exploring the phylogenetic affiliations and the trophic mode of Sedecula pulvinata (Sedeculaceae)

Creator:: Trappe, Matthew J., Smith, Matthew E., and Hobbie, Erik A.
Abstract:: Sedecula is a monotypic genus of hypogeous fungi that is rare and endemic to dry conifer forests of the western United States. The only known species, Sedecula pulvinata, was described in 1941 and its taxonomic placement and trophic status have remained uncertain ever since. Here we employ isotopic and molecular...

Assessing earth system model predictions of C-4 grass cover in North America: From the glacial era to the end of this century

Creator:: Still, Christopher J., Cotton, Jennifer M., and Griffith, Daniel M.
Abstract:: Aim C-4 grasses are distinct from C-3 grasses, because C-4 grasses respond in a different manner to light, temperature, CO2 and nitrogen and often have higher resource-use efficiencies. C-3 and C-4 grasses are typically represented in earth system models (ESMs) by different plant functional types (PFTs). The ability of ESMs...
