Encyclopedia of Global Resources part 37 provides a wide variety of perspectives on both traditional and more recent views of Earth's resources. It serves as a bridge connecting the domains of resource exploitation, environmentalism, geology, and biology, and it explains their interrelationships in terms that students and other nonspecialists can understand. The articles in this set are extremely diverse, with articles covering soil, fisheries, forests, aluminum, the Industrial Revolution, the . Department of the Interior, the hydrologic cycle, glass, and placer mineral deposits. . | 330 Ecology Global Resources evolutionary history developmental processes and behavioral adaptations and interactions of organisms from all over the world for the purpose of studying biodiversity. This type of study operates mainly at the levels of population species and communities and utilizes many subsets of ecology. Scientists employ paleoecology to establish historic patterns of biodiversity genetic ecology especially DNA techniques to study variation and to make genealogical connections among organisms telemetr y and satellites to study patterns in distribution of various species and computer simulations and field experimentation to test out hypotheses. Both genetic and evolutionar y ecology are important for the conservation of biodiversity and for developing applications to solve biological problems. Applied Ecology Ecology also involves many aspects of applied science in which the results of scientific study are applied to real-life situations from natural resource management to urban planning. Biotic natural resources have been managed at the individual and population levels since the agricultural revolution occurred eight thousand to ten thousand years ago. Until the 1960 s forestr y fish and wildlife management techniques were aimed at increasing the productivity of single species usually game species such as quail and trout or commercial tree species such as loblolly pine. As community ecology and ecosystem ecology matured and as popular concern for the loss of species arose in the 1960 s natural resource management agencies began to look at the effects of single-species management techniques on the entire community. Range management has always taken the community ecology perspective in managing native grass and shrub communities for livestock forage production. However range conser vationists also manage forage production for wildlife as well as for livestock. Conser vation biology applies the understanding of all ecological levels in the attempt to .
