Converging themes from the fields of environmental health, ecology and health, and human ecology highlight opportunities for innovation and advancement in environmental health theory and practice. In this commentary we outline the role of research and applied programs that integrate biophysical and social sciences with environmental health practice in order(More)
The time has come for a scientific journal that recognizes the inherent interdependence of the health of humans, wildlife, and ecosystems, and that provides a ‘‘gathering place’’ for those exploring the perspectives, theories, and methodologies emerging at the interface between ecological and health sciences. EcoHealth responds to this challenge and to the(More)
A survey of the literature shows that in many central actions, scopolamine has about 10 times the activity of atropine, whereas the ratio for most peripheral actions is nearer 2. For effects upon the eye, however, the ratio lies between 5 and 10, even when the drugs are applied locally. In a comparison of the central activities of a series of synthetic(More)
The increasing burden of emerging infectious diseases worldwide confronts us with numerous challenges, including the imperative to design research and responses that are commensurate to understanding the complex social and ecological contexts in which infectious diseases occur. A diverse group of scientists met in Hawaii in March 2005 to discuss the linked(More)
Ecohealth has emerged as a nexus of scholarly and practical effort at a time of considerable transition in research, policy, practice, and education. Amidst this flux, critical reflection is important, especially regarding where ecohealth is headed as a transdisciplinary field and how ecohealth positions itself among a series of iterative and converging(More)
The intimate interdependence of human health and the ecosystems in which we are embedded is now a commonplace observation. For much of the history of public health, this was not so obvious. After over a century of focus on diseases, their biologic causes and the correction of exposures (clean water and air) and facilitation of responses (immunizations and(More)
The effect of exposing mice to a hole-board in reducing the number of head dips made on a subsequent exposure was studied. The period of first exposure that was effective in causing this reduction, the interval between exposure that must elapse before this effect appears and the duration of the effect were also determined. Chlordiazepoxide and other(More)
Understanding links between catchment management and community health demands consideration of complex bio-physical, socio-economic, and public health relationships. These relationships cut across a spectrum of health, environment and development considerations and highlight the need for appropriate and integrative modes of inquiry and decision making. What(More)
In coupled social–ecological systems, the same driving forces can result in combined social and environmental health inequities, hazards, and impacts. Policies that decrease social inequities and improve social cohesion, however, also have the potential to improve health outcomes and to minimize and offset the drivers of ecosystem change. Actions that(More)
