The impacts of increasing drought on forest dynamics, structure, and biodiversity in the United States
(OxfordWiley Periodicals, Inc., 2016-07)
We synthesize insights from current understanding of drought impacts at stand‐to‐biogeographic scales, including management options, and we identify challenges to be addressed with new research. Large stand‐level shifts ...
Exposure to an enriched CO 2 atmosphere alters carbon assimilation and allocation in a pine forest ecosystem
(Blackwell Science Ltd, 2003-10)
We linked a leaf-level CO 2 assimilation model with a model that accounts for light attenuation in the canopy and measurements of sap-flux-based canopy conductance into a new canopy conductance-constrained carbon assimilation ...
Does anthropogenic nitrogen deposition induce phosphorus limitation in herbivorous insects?
(Springer‐VerlagWiley Periodicals, Inc., 2012-06)
Anthropogenic nitrogen deposition has shifted many ecosystems from nitrogen ( N ) limitation to phosphorus ( P ) limitation. Although well documented in plants, no study to date has explored whether N deposition ...
Environmental correlates of tree biomass, basal area, wood specific gravity and stem density gradients in Borneo's tropical forests
(Blackwell Publishing Ltd, 2010-01)
Aim Tropical forests have been recognized as important global carbon sinks and sources. However, many uncertainties about the spatial distribution of live tree above-ground biomass (AGB) remain, mostly due to limited ...
Climate and vegetational regime shifts in the late Paleozoic ice age earth
(Blackwell Publishing Ltd, 2009-03)
The late Paleozoic earth experienced alternation between glacial and non-glacial climates at multiple temporal scales, accompanied by atmospheric CO 2 fluctuations and global warming intervals, often attended by significant ...
The latitudinal gradient of beta diversity in relation to climate and topography for mammals in North America
(Blackwell Publishing Ltd, 2009-01)
Aim Spatial turnover of species, or beta diversity, varies in relation to geographical distance and environmental conditions, as well as spatial scale. We evaluated the explanatory power of distance, climate and topography ...
Scaling environmental change through the community-level: a trait-based response-and-effect framework for plants
(Blackwell Publishing Ltd, 2008-05)
Predicting ecosystem responses to global change is a major challenge in ecology. A critical step in that challenge is to understand how changing environmental conditions influence processes across levels of ecological ...
Soil organic matter and litter chemistry response to experimental N deposition in northern temperate deciduous forest ecosystems
(Blackwell Science Ltd, 2005-09)
The effects of atmospheric nitrogen (N) deposition on organic matter decomposition vary with the biochemical characteristics of plant litter. At the ecosystem-scale, net effects are difficult to predict because various ...
The global diversity and distribution of lizard clutch sizes
(Johns Hopkins University PressWiley Periodicals, Inc., 2020-09)
AimClutch size is a key life- history trait. In lizards, it ranges over two orders of magnitude. The global drivers of spatial and phylogenetic variation in clutch have been extensively studied in birds, but such tests ...
Rewiring coral: Anthropogenic nutrients shift diverse coral–symbiont nutrient and carbon interactions toward symbiotic algal dominance
(Springer‐VerlagWiley Periodicals, Inc., 2020-10)
Improving coral reef conservation requires heightened understanding of the mechanisms by which coral cope with changing environmental conditions to maintain optimal health. We used a long‐term (10 month) in situ experiment ...
