Montane Meadows as Indicators of Environmental Change

We used a time series of satellite multispectral imagery for mapping and monitoring six classes of montane meadows arrayed along a moisture gradient (from hydric to mesic to xeric). We hypothesized that mesic meadows would support the highest species diversity of plants, birds, and butterflies because they are more moderate environments. We also hypothesized that mesic meadows would exhibit the...

Orchids as Indicators of Ecosystem Health in Urban Bushland Fragments

Pfiesteria: harmful algal blooms as indicators of human: ecosystem interactions.

As man continues to expand and to develop large land areas near surface waters the pollution of these waters will intensify. Historically man has used lakes and rivers for waste disposal with little regard to the effects of these wastes on the receiving waters . . . With the predicted population growth and subsequent demands on the environment, the frequency with which recreational and muncipal...

3 Ecosystem Indicators

There are many types of indicators, including those of the physical environment (e.g., climate), ecological, and socio-economic conditions. There is an entire professional journal devoted to the topic, called Ecological Indicators. Within marine systems, the most recent focus has been on developing indicators for ecosystem-based fisheries management (EBFM). Significant recent literature on this...
