Altered Belowground Carbon Cycling Following Land-Use Change to Perennial Bioenergy Crops
Springer Science and Business Media LLC - Tập 16 - Trang 508-520 - 2013
Belowground carbon (C) dynamics of terrestrial ecosystems play an important role in the global C cycle and thereby in climate regulation. Globally, land-use change is a major driver of changes in belowground C storage. The emerging bioenergy industry is likely to drive widespread land-use changes, including the replacement of annually tilled croplands with perennial bioenergy crops, and thereby to...... hiện toàn bộ
Cross-Scale Patterns in Shrub Thicket Dynamics in the Virginia Barrier Complex
Springer Science and Business Media LLC - Tập 10 - Trang 854-863 - 2007
To interpret broad-scale erosion and accretion patterns and the expansion and contraction of shrub thickets in response to sea level rise for a coastal barrier system, we examined the fine-scale processes of shrub recruitment and mortality within the context of the influence of ocean current and sediment transport processes on variations in island size and location. We focused on Myrica cerifera s...... hiện toàn bộ
Shoot-Level Flammability of Species Mixtures is Driven by the Most Flammable Species: Implications for Vegetation-Fire Feedbacks Favouring Invasive Species
Springer Science and Business Media LLC - Tập 21 - Trang 886-900 - 2017
Invasive species can cause shifts in vegetation composition and fire regimes by initiating positive vegetation-fire feedbacks. To understand the mechanisms underpinning these shifts, we need to determine how invasive species interact with other species when burned in combination and thus how they may influence net flammability in the communities they invade. Previous studies using litter and grou...... hiện toàn bộ
Direct and Indirect Effects of Dissolved Organic Matter Source and Concentration on Denitrification in Northern Florida Rivers
Springer Science and Business Media LLC - Tập 17 - Trang 14-28 - 2013
Using a natural gradient of dissolved organic carbon (DOC) source and concentration in rivers of northern Florida, we investigated how terrestrially-derived DOC affects denitrification rates in river sediments. Specifically, we examined if the higher concentrations of DOC in blackwater rivers stimulate denitrification, or whether such terrestrially-derived DOC supports lower denitrification rates ...... hiện toàn bộ
Comparison of the Higher-Severity Fire Regime in Historical (A.D. 1800s) and Modern (A.D. 1984–2009) Montane Forests Across 624,156 ha of the Colorado Front Range
Springer Science and Business Media LLC - Tập 15 - Trang 832-847 - 2012
There are concerns that recent fires, following a century of land uses, are burning in dry western forests in an uncharacteristic manner with large patches of higher-severity fire affecting long-term ecosystem dynamics. For example, it is well documented that a mixed-severity fire regime predominated over montane forests of the Colorado Front Range. However, much about the historical fire regime i...... hiện toàn bộ
Shifts in Key Leaf Litter Traits Can Predict Effects of Plant Diversity Loss on Decomposition in Streams
Springer Science and Business Media LLC - Tập 24 - Trang 185-196 - 2020
Plant biodiversity loss in riparian forests is known to alter key stream ecosystem processes such as leaf litter decomposition. One potential mechanism mediating this biodiversity–decomposition relationship is the increased variability of plant functional traits at higher levels of biodiversity, providing more varied resources for decomposers and thus improving their function. We explored this in ...... hiện toàn bộ
Effects of Extreme Weather Events on Plant Productivity and Tissue Die-Back are Modified by Community Composition

Bridging Disciplinary Divides to Address Environmental and Intellectual Challenges

Soil Microbes Compete Strongly with Plants for Soil Inorganic and Amino Acid Nitrogen in a Semiarid Grassland Exposed to Elevated CO2 and Warming
Springer Science and Business Media LLC - Tập 18 - Trang 867-880 - 2015
Free amino acids (FAAs) in soil are an important N source for plants, and abundances are predicted to shift under altered atmospheric conditions such as elevated CO2. Composition, plant uptake capacity, and plant and microbial use of FAAs relative to inorganic N forms were investigated in a temperate semiarid grassland exposed to experimental warming and free-air CO2 enrichment. FAA uptake by two ...... hiện toàn bộ
Cross-Scale Modeling of Riparian Ecosystem Responses to Hydrologic Management
Springer Science and Business Media LLC - Tập 2 - Trang 411-421 - 1999
There is much demand for quantitative models to aid in comparison of policy options and design of adaptive management policies for riparian ecosystems. Such models must represent a wide variety of physical and biological factors that can vary on space–time scales from meters-seconds to basin-decades. It is not possible in practice to develop a complete model for all variation. Incomplete but sti...... hiện toàn bộ
