The hydrology of the humid tropics

Creator:: Wohl, Ellen, Barros, Ana, Brunsell, Nathaniel, Chappell, Nick A., Coe, Michael, Giambelluca, Thomas, Goldsmith, Steven, Harmon, Russell, Hendrickx, Jan M. H., Juvik, James, McDonnell, Jeffrey, and Ogden, Fred
Abstract:: Hydrological processes in the humid tropics differ from other regions in having greater energy inputs and faster rates of change, including human-induced change. Human influences on population growth, land use and climate change will profoundly influence tropical hydrology, yet understanding of key hydrological interactions is limited. We propose that efforts...

Overstory density and disturbance impacts on the resilience of coniferous forests of western Oregon

Creator:: Neill, Andrew R.
Abstract:: A trait based approach was used to assess impacts of overstory density and thinning on understory vegetation components related to wildlife habitat. The relationship between overstory basal area and understory vegetation for species grouped by traits, such as production of flowers, fleshy-fruit and palatable leaves, was characterized in thinned and...

Mapping the Global Emergence of Batrachochytrium dendrobatidis, the Amphibian Chytrid Fungus

Creator:: Olson, Deanna H., Aanensen, David M., Ronnenberg, Kathryn L., Powell, Christopher I., Walker, Susan F., Bielby, Jon, Garner, Trenton W. J., Weaver, George, The Bd Mapping Group, and Fisher, Matthew C.
Abstract:: The rapid worldwide emergence of the amphibian pathogen Batrachochytrium dendrobatidis (Bd) is having a profound negative impact on biodiversity. However, global research efforts are fragmented and an overarching synthesis of global infection data is lacking. Here, we provide results from a community tool for the compilation of worldwide Bd presence...

Homogenization of Detrital Leachate in an Old-Growth Coniferous Forest, OR : DOC Fluorescence Signatures in Soils Undergoing Long-Term Litter Manipulations

Creator:: Strid, April R.
Abstract:: Soil dissolved organic carbon (DOC) is a small but crucial part of the forest carbon cycle. Characterizing the relationship between detrital inputs and soil DOC chemistry is crucial to understanding the ultimate fate of root carbon, fallen wood and needles. Chemical differences in the DOC pool may help to explain...

Long-term Effects of Vegetation Management on Biomass Stock and Aboveground Net Primary Productivity of Four Coniferous Species in the PNW

Creator:: Flamenco, Herman N., Jr.
Abstract:: Forest vegetation management (FVM) is an important component of reforestation in the Pacific Northwest (PNW). Several studies have demonstrated the benefits of vegetation management on planted conifer growth and survival. However, few reports have been published on the long-term effects of FVM treatments on total ecosystem biomass accumulation and aboveground...

Moving water well: comparing hydraulic efficiency in twigs and trunks of coniferous, ring-porous, and diffuse-porous saplings from temperate and tropical forests

Creator:: McCulloh, Katherine A., Sperry, John S., Lachenbruch, Barbara, Meinzer, Frederick C., Reich, Peter B., and Voelker, Steven
Abstract:: • Coniferous, diffuse‐porous and ring‐porous trees vary in their xylem anatomy, but the functional consequences of these differences are not well understood from the scale of the conduit to the individual. • Hydraulic and anatomical measurements were made on branches and trunks from 16 species from temperate and tropical areas,...

Catchment-Scale Modeling of Nitrogen Dynamics in a Temperate Forested Watershed, Oregon. An Interdisciplinary Communication Strategy

Creator:: Vaché, Kellie, Breuer, Lutz, Jones, Julia A., and Sollins, Phil
Abstract:: We present a systems modeling approach to the development of a place-based ecohydrological model. The conceptual model is calibrated to a variety of existing observations, taken in watershed 10 (WS10) at the HJ Andrews Experimental Forest (HJA) in Oregon, USA, a long term ecological research (LTER) site with a long...

Interactions Between Wild Bee Communities and Douglas-fir Beetle (Dendroctonus pseudotsugae) Populations in Douglas-fir (Pseudotsugae menziezii) Forests of the Intermountain West

Creator:: Foote, Gabriel G.
Abstract:: This work combines both applied and basic research regarding previously undescribed relationships between two ecologically and economically important insect groups in coniferous forests, bark beetles (Coleoptera: Curculionidae, Scolytinae) and wild bee (Hymenoptera: Apiformes) communities in Western North America. Across the continent, native bark beetle outbreaks are key drivers of structural...

Using soil data to enhance modeling of forest responses to climate change

Creator:: Peterman, Wendy L.
Abstract:: The over-arching theme of this work is that soil data affect the performance and realism of vegetation models with particular focus on their ability to predict or explain disturbances such as fire or disease. We tested the sensitivity of the Excel version of the 3-PG model to soil properties and...

The use of remote sensing for characterizing forests in wildlife habitat modeling

Creator:: Vogeler, Jody C.
Abstract:: Spatially explicit maps of habitat relationships have proven to be valuable tools for conservation and management applications including evaluating how and which species may be impacted by large scale climate change, ongoing fragmentation of habitat, and local land-use practices. Studies have turned to remote sensing datasets as a way to...
