Vomeronasal receptor genes have frequently been invoked as integral to the establishment and maintenance of species boundaries among mammals due to the elaborate one-to-one correspondence between semiochemical signals and neuronal sensory inputs. Here, we report the most extensive sample of vomeronasal receptor class 1 (V1R) sequences ever generated for a(More)
SIR — Shocking new proof of an emerging trade in lemur bushmeat in Madagascar (see http://tinyurl. com/mqsx7w) is refocusing attention on the conservation and health challenges in one of the world’s most important biodiversity hotspots. The growth of this market, in which lemurs are sold as a delicacy to luxury consumers, could mean extinction for(More)
Big data is often discussed in the context of improving medical care, but it also has a less appreciated but equally important role to play in preventing disease. Big data can facilitate action on the modifiable risk factors that contribute to a large fraction of the chronic disease burden, such as physical activity, diet, tobacco use, and exposure to(More)
Anthropogenic habitat disturbance impairs ecosystem health by fragmenting forested areas, introducing environmental contamination, and reducing the quality of habitat resources. The effect of this disturbance on wildlife health is of particular concern in Madagascar, one of the world's biodiversity hotspots, where anthropogenic pressures on the environment(More)
Federal, state, and local park agencies across the nation have faced budget cuts in recent years as a result of the economic downturn and sequestration, resulting in park closures, reduced hours, staffing cuts, and deferred maintenance. For example, California faced closure of 70 state parks in 2012 to trim $22 million from the strapped state budget.(More)
L ogging in Madagascar, one of the world’s most threatened biodiversity hot spots ( 1, 2), has rapidly increased amid political turmoil since a transitional government assumed power in March 2009 ( 1, 3). With as much as 90% of the country’s primary forest already lost, continued logging will mean species extinctions across all biotic elements of(More)
Issues of global environmental change, global health, emerging disease, and sustainability present some of the most complex challenges of the twenty-first century. Individual disciplines cannot address these issues in isolation. Proactive, innovative, and trans-disciplinary solutions are required. Recognizing the inherent connectedness of humans, animals,(More)
Implementation of the coalescent model in a Bayesian framework is an emerging strength in genetically based species delimitation studies. By providing an objective measure of species diagnosis, these methods represent a quantitative enhancement to the analysis of multilocus data, and complement more traditional methods based on phenotypic and ecological(More)
BACKGROUND Epidemiological asthma research has relied upon self-reported symptoms or healthcare utilization data, and used the residential address as the primary location for exposure. These data sources can be temporally limited, spatially aggregated, subjective, and burdensome for the patient to collect. OBJECTIVES First, we aimed to test the(More)
