BOISE, Idaho — The network of greater sage-grouse priority areas is a highly centralized system of conservation reserves. The largest priority areas likely can support sage-grouse populations within their boundaries, but smaller priority areas will need to rely on their neighbors in the surrounding network to sustain local populations, according to new research by the U.S. Geological Survey.

From the 1880s to the 1950s, the U.S. Geological Survey (USGS) engraved information from its surveys on metal plates (usually copper) as part of a lithographic printing process to reproduce topographic and geologic maps, geologic cross sections, and other illustrations. The engraved plates show point and line symbols and text for topography, hydrography, geology, and cultural features.

In a paper released today in Science, a new model presents a common mathematical structure that underlies the full range of feeding strategies of plants and animals: from familiar parasites, predators, and scavengers to more obscure parasitic castrators and decomposers. Now ecologists can view all food-web interactions through the same lens using a common language to understand the natural world.
