Modeling wet headwater stream networks across multiple flow conditions in the Appalachian Highlands
Despite the advancement of remote sensing and geospatial technology in recent decades, maps of headwater streams continue to have high uncertainty and fail to adequately characterize temporary streams that expand and ...
Trust ecology and the resilience of natural resource management institutions
(The Resilience Alliance, 2015)
The resilience of natural resource management (NRM) institutions are largely contingent on the capacities of the people and organizations within those institutions to learn, innovate, and adapt, both individually and ...
Global patterns of lake ice phenology and climate: Model simulations and observations
(American Geophysical Union, 1998-11-27)
Lake ice phenology parameters (dates of ice onset and thaw) provide an integrative climatic description of autumn to springtime conditions. Interannual variations in lake ice duration and thickness allow estimates of local ...
Edaphic and climatic effects on forest stand development, net primary production, and net ecosystem productivity simulated for Coastal Plain loblolly pine in Virginia
(American Geophysical Union, 2008-01-11)
We used SECRETS-3PG to simulate net primary production (NPP) and net ecosystem productivity (NEP) of loblolly pine (Pinus taeda L.) growing on the Virginia Coastal Plain, focusing on the effects of soils and climate, and ...
Biodiversity conservation in the era of biofuels: risks and opportunities
(Ecological Society of America, 2011-04)
Growing demand for alternative energy sources has contributed to increased biofuel production, but the effects on biodiversity of land-use change to biofuel crops remain unclear. Using a meta-analysis for crops being used ...
Low mortality in tall tropical trees
(Ecological Society of America, 2013-04)
The dynamics of the tallest trees in tropical forests are of special interest due to their carbon content, canopy dominance, and the large canopy gaps created when they die. Known ecological mechanisms that may influence ...
accuracy of visible and ultraviolet light for estimating live root proportions with minirhizotrons
(Ecological Society of America, 1995-10)
Growth, Collapse, and Reorganization of the Annapurna Conservation Area, Nepal: an Analysis of Institutional Resilience
(Resilience Alliance, 2010)
Community-based conservation institutions can be conceptualized as complex adaptive systems that pass through a cycle of growth, maturation, collapse, and reorganization. We test the applicability of this four-phase adaptive ...
on estimating aboveground weights of tree stands
(Ecological Society of America, 1975)
Simulated sampling of nine tree stands was used to compare estimated stand component weights with known weights based on complete harvest. On average, estimates based on regressions of logarithm weight on either logarithm ...
sampling-skewed biological populations: behavior of confidence intervals for the population total
(Ecological Society of America, 1999-04)
Four populations were repeatedly sampled with the aim of examining interval estimation of the cumulative amount, T, of some characteristic that has a positively skewed distribution, a feature of many biological populations. ...
