For forecasting, source-tracing, and sustainable management, we explored from a broad field of vet medicine to ecological practice. How to bridge the gap between ecology, medicine, vet medicine, and other related disciplines is our interest. But a simple “joint-venture” of these disciplines doesn’t work. Our practical experiences imply a possibility of the essential of diseases as a crisis of ecosystem, which expands our scope of the understanding of zoonosis and gives us an opportunity to verify it by the way of inter-discipline effort. Now we re-define these issues in an integrated way. This motivates us to monitor the common health of livings (wildlife, livestock, and human being), the environment, and the ecosystem, from the scopes of homeostasis (ROS system), fitness (for example, telomere testing) and diseases of individuals, Eco-toxicity and the assessment of the structure and functions of an ecosystem (i.e. biodiversity and ecosystem service). We have been practicing in a broad geographical range in China, wild species, and pathogens.
