||Published by Cambridge Scientific Abstracts, Ecology Abstracts covers journal literature pertaining to the relationships of organisms to each other and to their environments. About 285 journals are indexed, some completely, others, selectively. Included are relevant papers on evolutionary biology, economics, and systems analysis as they relate to ecosystems or the environment. There is detailed information on resource and ecosystems management and modeling as well as material on the impact of climate, water resources, soil, and man on environmental problems such as depletion, erosion, and pollution. Major areas of coverage include: algae/lichens, animals, annelids, aquatic ecosystems, arachnids, arid zones, birds, brackish water, bryophytes/pteridophytes, coastal ecosystems, conifers, conservation, crustaceans, fungi, grasses, grasslands, high altitude environments, human ecology, insects, legumes, mammals, microorganisms, mollusks, nematodes, paleo-ecology, plants, reptiles, river basins, soil, taiga/tundra, terrestrial ecosystems, vertebrates, wetlands, and woodlands. Online coverage extends back to 1982.

|Encyclopedia of Life Sciences Online (Nature)
||Published by Nature, the Encyclopedia of Life Sciences (ELS) is very comprehensive, comprised of over 3,000 original peer-reviewed articles, organized by subject and of three different academic levels (beginning undergraduate, advanced undergraduate and graduate, special essay). ELS is searchable by keywords and can be browsed by subject area. It is extensively cross-referenced and indexed and provides direct links from references to the primary literature as well as to other scientific websites. At least 20% of its content is updated each year.
