Connecting Inventory Information Sources for Landscape Level Analyses

Creator:: Lemay, Valerie and Temesgen, Hailemariam
Abstract:: In forest landscape level analyses, forest information is commonly represented by separate polygons, defined by differences in species composition, stand structure, crown closure, and productivity. The simplest approach to projecting yield of stands over the land base is to create an aggregated yield table, weighted by area of each stand...

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...

Decomposition and nitrogen release from decomposing woody roots in coniferous forests of the Pacific Northwest: a chronosequence approach

Creator:: Chen, Hua, Harmon, Mark E., and Griffiths, Robert P.
Abstract:: Decomposition of woody roots in Sitka spruce (Picea sitchensis (Bong.) Carrière), Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), and ponderosa pine (Pinus ponderosa P. Laws. ex C. Laws.) dominated forests in Oregon, U.S.A. was studied using a chronosequence. Roots of five coniferous species were excavated from stumps with ages up to 46...

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...

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...

Simulating Current Successional Trajectories in Sagebrush Ecosystems With Multiple Disturbances Using a State-and-Transition Modeling Framework

Creator:: Evers, Louisa B., Miller, Richard F., Doescher, Paul S., Hemstrom, Miles, and Neilson, Ronald P.
Abstract:: Disturbances and their interactions play major roles in sagebrush (Artemisia spp. L.) community dynamics. Although impacts of some disturbances, most notably fire, have been quantified at the landscape level, some have been ignored and rarely are interactions between disturbances evaluated. We developed conceptual state-and-transition models for each of two broad...

Automated reconstruction of tree and canopy structure for modeling the internal canopy radiation regime

Creator:: van Leeuwen, Martin, Coops, Nicholas C., Hilker, Thomas, Wulder, Michael A., Newnham, Glenn J., and Culvenor, Darius S.
Abstract:: Understanding canopy radiation regimes is critical to successfully modeling vegetation growth and function. For instance, the vertical distribution of photosynthetically active radiation (PAR) affects vegetation growth, informative upon carbon and energy cycling. Availing upon advances in information capture and computing power, geometrically explicit modeling of forest structure becomes increasingly possible....

Viewing forests through the lens of complex systems science

Abstract:: Complex systems science provides a transdisciplinary framework to study systems characterized by (1) heterogeneity, (2) hierarchy, (3) self‐organization, (4) openness, (5) adaptation, (6) memory, (7) non‐linearity, and (8) uncertainty. Complex systems thinking has inspired both theory and applied strategies for improving ecosystem resilience and adaptability, but applications in forest ecology...

Nutrient stores and dynamics of woody detritus in a boreal forest: modeling potential implications at the stand level

Creator:: Krankina, Olga N., Harmon, Mark E., and Griazkin, Anatolii V.
Abstract:: Concentrations of 14 chemical elements (Al, B, C, Ca, Cu, Fe, K, N, Mg, Mn, Na, P, S, Zn) were measured in wood and bark of 126 sample trees representing different stages of decomposition in three major tree species of northwestern Russia: Scots pine (Pinus sylvestris L.), Norway spruce (Picea...
