Rivers are essential to aquatic ecosystem and societal sustainability, but are increasingly impacted by water withdrawals, land-use change, and climate change. The relative and cumulative effects of these stressors on continental river flows are relatively unknown. In this study, we used an integrated water balance and flow routing model to evaluate the(More)
Ten lions (Panthera leo) that were treated with a single injection of doramectin at a dose ranging between 0.2 mg/kg and 0.5 mg/kg showed clinical signs consistent with avermectin toxicity, namely ataxia, hallucinations, and mydriasis. Two subsequently died whereas the other eight lions recovered after 4-5 days with symptomatic therapy. Post-mortem(More)
s u m m a r y Urban reforestation in China has led to increasing debate about the impact of urban trees and forests on water resources. Although transpiration is the largest water flux leaving terrestrial ecosystems, little is known regarding whole tree transpiration in urban environments. In this study, we quantified urban tree transpiration at various(More)
Stream water temperature (t s) is a critical water quality parameter for aquatic ecosystems. However, t s records are sparse or nonexistent in many river systems. In this work, we present an empirical model to predict t s at the site scale across the USA. The model, derived using data from 171 reference sites selected from the Geospatial Attributes of Gages(More)
Oxidation of ribosomal protein L12 with hydrogen peroxide converts the three methionine residues to methionine sulfoxide. The oxidized protein has a decreased ability to bind to ribosomes, interact with ribosomal protein L10, be precipitated by L12 antiserum, and serve as substrate for the acetylating enzyme that converts L12 to L7. Full activity of L12 is(More)
We perform a multimodel detection and attribution study with climate model simulation output and satellite-based measurements of tropospheric and stratospheric temperature change. We use simulation output from 20 climate models participating in phase 5 of the Coupled Model Intercomparison Project. This multimodel archive provides estimates of the signal(More)
Water is a critical resource of the Southern United States and is intimately linked to other ecosystem and societal values. The South is known for its warm climate, rich water resources (Figure 9.1), and large acreage of forest lands that provide an ideal place for people to live. Indeed, water availability is central to sustaining an economy that relies on(More)
Future climate and land-use changes and growing human populations may reduce the abundance of water resources relative to anthropogenic and ecological needs in the Northeast and Midwest (U.S.). We used output from WaSSI, a water accounting model, to assess potential changes between 2010 and 2060 in (1) anthro-pogenic water stress for watersheds throughout(More)
The goal of this study was to test the sensitivity of water yield to forest thinning and other forest management/disturbances and climate across the conterminous United States (CONUS). Leaf area index (LAI) was selected as a key parameter linking changes in forest ecosystem structure and functions. We used the Water Supply Stress Index model to examine(More)
