The abiotic and biotic drivers of rapid diversification in Andean bellflowers (Campanulaceae)
(John Wiley and Sons Inc., 2016)Summary The tropical Andes of South America, the world's richest biodiversity hotspot, are home to many rapid radiations. While geological, climatic, and ecological processes collectively explain such radiations, their ... -
Additive Damages, Fat-Tailed Climate Dynamics, and Uncertain Discounting
(Economics, 2009)This paper in applied theory argues that there is a loose chain of reasoning connecting the following three basic links in the economics of climate change: 1) additive disutility damages may be appropriate for analyzing ... -
Amazon Forest Response to Changes in Rainfall Regime: Results from an Individual-Based Dynamic Vegetation Model
(2014-02-25)The Amazon is the largest tropical rainforest in the world, and thus plays a major role on global water, energy, and carbon cycles. However, it is still unknown how the Amazon forest will respond to the ongoing changes ... -
Assessing the Air Pollution Health and Climate Impacts of Transportation as the U.S. Shifts to Electric and Autonomous Vehicles
(2021-03-05)Vehicles remain a major climate and public health issue in the United States despite decades of regulation. In order to mitigate this burden, electric vehicles (EVs) are starting to be deployed in larger numbers, and there ... -
Climate change alters temperate tree and shrub spring phenology and false spring risk
(2021-08-24)Temperate tree and shrub species are at risk of damage from late spring freezing events. Individuals that initiate budburst before the last spring freeze risk leaf tissue loss, damage to the xylem, and slowed, or even ... -
Climate Change and Global Food Systems: Potential Impacts on Food Security and Undernutrition
(Annual Reviews, 2017)Great progress has been made in addressing global undernutrition over the past several decades, in part because of large increases in food production from agricultural expansion and intensification. Food systems, however, ... -
Climate Change and the Integrity of Science
(American Association for the Advancement of Science, 2010)We are deeply disturbed by the recent escalation of political assaults on scientists in general and on climate scientists in particular. All citizens should understand some basic scientific facts. There is always some ... -
Climate response to the increase in tropospheric ozone since preindustrial times: A comparison between ozone and equivalent CO 2 forcings
(Wiley-Blackwell, 2004)We examine the characteristics of the climate response to anthropogenic changes in tropospheric ozone. Using a general circulation model, we have carried out a pair of equilibrium climate simulations with realistic present-day ... -
A Climatic Driver for Abrupt Mid-Holocene Vegetation Dynamics and the Hemlock Decline in New England
(Ecological Society of America, 2006)The mid-Holocene decline of eastern hemlock is widely viewed as the sole prehistorical example of an insect- or pathogen-mediated collapse of a North American tree species and has been extensively studied for insights into ... -
Climatic Drivers of Hemispheric Asymmetry in Global Patterns of Ant Species Richness
(Blackwell Science, 2009)Although many taxa show a latitudinal gradient in richness, the relationship between latitude and species richness is often asymmetrical between the northern and southern hemispheres. Here we examine the latitudinal pattern ... -
Common Garden Experiments Reveal Uncommon Responses across Temperatures, Locations, and Species of Ants
(Wiley Open Access, 2012-10-12)Population changes and shifts in geographic range boundaries induced by climate change have been documented for many insect species. On the basis of such studies, ecological forecasting models predict that, in the absence ... -
Correlations between Fine Particulate Matter \((PM_{2.5})\) and Meteorological Variables in the United States: Implications for the Sensitivity of \(PM_{2.5}\) to Climate Change
(Elsevier, 2010)We applied a multiple linear regression (MLR) model to study the correlations of total \(PM_{2.5}\) and its components with meteorological variables using an 11-year (1998–2008) observational record over the contiguous US. ... -
Effect of Climate Change on Air Quality
(Elsevier, 2009)Air quality is strongly dependent on weather and is therefore sensitive to climate change. Recent studies have provided estimates of this climate effect through correlations of air quality with meteorological variables, ... -
Effects of Short-Term Warming On Low and High Latitude Forest Ant Communities
(Ecological Society of America, 2011)Climatic change is expected to have differential effects on ecological communities in different geographic areas. However, few studies have experimentally demonstrated the effects of warming on communities simultaneously ... -
Environmental Spiral: Scientific Mediation in Twentieth-Century American Poetry
(2013-08-28)This dissertation asks how the heightening of artistic and scientific mediation has affected the representation of the environment in modernist and contemporary American poetry. In chapters on Marianne Moore, A.R. Ammons, ... -
Essays on the Economics of Climate Change
(2012-07-25)This dissertation studies three aspects of the economics of climate change: how rising sea levels will affect coastal homeowners in Florida; how changes in weather will affect the prevalence of crime in the United States; ... -
The Fate of an Engineered Planet
(Nature Publishing Group, 2013)Solar engineering and other exceptionally ambitious new technologies to deal with the reality of rising global temperatures come riddled with uncertainties. To illustrate how complex the problem is and what kind of challenges ... -
Gender and Sexuality in U.S. Biodiversity Discourse
(2022-07-28)This dissertation examines the role of gender and sexuality in discourses surrounding the biodiversity crisis that threatens the future of most known species, including humans. I examine the gendered rhetoric that biodiversity ... -
Heating Up the Forest: Open-Top Chamber Warming Manipulation of Arthropod Communities at Harvard and Duke Forests
(John Wiley & Sons, 2011)1. Recent observations indicate that climatic change is altering biodiversity, and models suggest that the consequences of climate change will differ across latitude. However, long-term experimental field manipulations ... -
Herbarium records are reliable sources of phenological change driven by climate and provide novel insights into species’ phenological cueing mechanisms
(Botanical Society of America, 2015)Premise of the study: Climate change has resulted in major changes in the phenology of some species but not others. Long-term field observational records provide the best assessment of these changes, but geographic and ...
