A Helicopter Observation Platform for Atmospheric Boundary Layer Studies
(2009)Spatial variability of the Earth's surface has a considerable impact on the atmosphere at all scales and understanding the mechanisms involved in land-atmosphere interactions is hindered by the scarcity of appropriate ... -
A novel approach to assess livestock management effects on biodiversity of drylands
(Ecological Indicators, 2015-01-01)In drylands livestock grazing is the main production activity, but overgrazing due to mismanagement is a major cause of biodiversity loss. Continuous grazing around water sources generates a radial gradient of grazing intensity ... -
A tale of three disciplines: Navigating the Boundaries at the Nexus of Conservation Science, Policy, and Practice
(2009)Nature is under immediate and increasing threat. Tales of destruction and deforestation abound despite the myriad interventions and investments by government bureaucracies, non-government organizations, and private land-owners. ... -
A Time Series Regression Analysis of Future Climate
(2012-04-23)Current approaches to climate modeling, including environmental simulation, may not be able to generate actionable results for a few decades yet. Over the last 50 years, methods attempting to capture and predict states of ... -
Amazon Climate Reconstruction Using Growth Rates and Stable Isotopes of Tree Ring Cellulose from the Madre De Dios Basin, Peru
(2009)The Amazon basin is a center of deep atmospheric convection and thus acts as a major engine for global atmospheric circulation. From this basin, one fifth of the world's freshwater flux is discharged into the Atlantic and ... -
Assessing the effectiveness of the Neuse nitrogen TMDL program and its impacts on estuarine chlorophyll dynamics
(2011)Coastal eutrophication is a complex process that is caused largely by anthropogenic nutrient enrichment. Estuaries are particularly susceptible to nutrient impairment, owing to their intimate connection with the contributing ... -
A Multiscale Investigation of Snake Habitat Relationships and Snake Conservation in Illinois
(2008-02-11)Snake populations in the North American tallgrass prairie appear to be declining, yet data unavailability impedes the development of enhanced ecological understanding of snake species-habitat relationships and also hinders ... -
Bayesian Methods to Characterize Uncertainty in Predictive Modeling of the Effect of Urbanization on Aquatic Ecosystems
(2010)Urbanization causes myriad changes in watershed processes, ultimately disrupting the structure and function of stream ecosystems. Urban development introduces contaminants (human waste, pesticides, industrial chemicals). ... -
Behavior, Ecology, and Conservation of Sea Turtles in the North Atlantic Ocean
(2009)Sea turtles have experienced dramatic population declines during the last century as a consequence of direct harvest, by-catch in fisheries, and habitat loss. Despite almost 50 years of partial international protection, ... -
Biodegradation of a Sulfur-Containing PAH, Dibenzothiophene, by a Mixed Bacterial Community
(2009)Dibenzothiophene (DBT) is a constituent of creosote and petroleum waste contamination, it is a model compound for more complex thiophenes, and its degradation by mixed microbial communities has received little attention. ... -
Biomass offsets little or none of permafrost carbon release from soils, streams, and wildfire: An expert assessment
(Environmental Research Letters, 2016-03-07)As the permafrost region warms, its large organic carbon pool will be increasingly vulnerable to decomposition, combustion, and hydrologic export. Models predict that some portion of this release will be offset by increased ... -
Carbon and Water Relations in Pinus Taeda: Bridging the Gap across Plant Physiology, Genomics, and Global Climate Change
(2008-06-23)Plants respond to changes in their local environment and, at the same time, influence the environment at a global scale. The molecular and physiological mechanisms regulating this interaction are not completely understood ... -
Changes in evapotranspiration and phenology as consequences of shrub removal in dry forests of central Argentina
(Ecohydrology, 2015-10-01)More than half of the dry woodlands (forests and shrublands) of the world are in South America, mainly in Brazil and Argentina, where in the last years intense land use changes have occurred. This study evaluated how the ... -
Climate and health impacts of US emissions reductions consistent with 2 °C
(Nature Climate Change, 2016-05)© 2016 Macmillan Publishers Limited. All rights reserved. An emissions trajectory for the US consistent with 2 °C warming would require marked societal changes, making it crucial to understand the associated benefits. Previous ... -
Climate change challenges the current conservation strategy for the giant panda
(Biological Conservation, 2015-10-01)The global total of protected areas to conserve biodiversity is increasing steadily, while numerous studies show that they are broadly effective. That said, how will current conservation strategies work, given the current ... -
Coastal Plain Pond Vegetation Patterns: Tracking Changes Across Space and Time
(2010)Coastal plain ponds are an understudied and threatened wetland ecosystem with many unique environmental attributes. Research in these ponds can investigate species-environment relationships, while simultaneously providing ... -
Conceptualizing and operationalizing human wellbeing for ecosystem assessment and management
(Environmental Science and Policy, 2016-12-01)© 2016 Elsevier Ltd There is growing interest in assessing the effects of changing environmental conditions and management actions on human wellbeing. A challenge is to translate social science expertise regarding these ... -
Conserving Moving Species under Changing Landscapes and Climates
(2008-08-04)To conserve biodiversity, it is critical to understand the dynamic landscapes and climates through which species move and how the environment influences movement choices. In particular, I am interested in how species respond ... -
Creating linked datasets for SME energy-assessment evidence-building: Results from the U.S. Industrial Assessment Center Program
(Energy Policy, 2017-12-01)© 2017 Elsevier Ltd Lack of information is commonly cited as a market failure resulting in an energy-efficiency gap. Government information policies to fill this gap may enable improvements in energy efficiency and social ... -
Defaunation of large mammals alters understory vegetation and functional importance of invertebrates in an Afrotropical forest
(Biological Conservation, 2020-01-01)Hunting has reduced or eliminated large-bodied vertebrates in many areas across the tropics, contributing to the global process of defaunation. Elucidating the ecological consequences of hunting has important implications ...
