Ecology is the study of the relationships among living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history.
This is an index of conservation topics. It is an alphabetical index of articles relating to conservation biology and conservation of the natural environment.
Habitat conservation is a management practice that seeks to conserve, protect and restore habitats and prevent species extinction, fragmentation or reduction in range. It is a priority of many groups that cannot be easily characterized in terms of any one ideology.
Applied ecology is a sub-field within ecology that considers the application of the science of ecology to real-world questions. It is also described as a scientific field that focuses on the application of concepts, theories, models, or methods of fundamental ecology to environmental problems.
Ecology is a new science and considered as an important branch of biological science, having only become prominent during the second half of the 20th century. Ecological thought is derivative of established currents in philosophy, particularly from ethics and politics.
Ecological engineering uses ecology and engineering to predict, design, construct or restore, and manage ecosystems that integrate "human society with its natural environment for the benefit of both".
Ecological restoration is the process of assisting the recovery of an ecosystem that has been degraded, damaged, or destroyed. It is distinct from conservation and preservation in that it is an "attempt to co-design nature with nonhuman collaborators." Ecological restoration can reverse biodiversity loss, combat climate change, and support local economies. The United Nations named 2021-2030 the Decade on Ecosystem Restoration.
Ecosystem services are the many and varied benefits to humans provided by the natural environment and healthy ecosystems. Such ecosystems include, for example, agroecosystems, forest ecosystem, grassland ecosystems, and aquatic ecosystems. These ecosystems, functioning in healthy relationships, offer such things as natural pollination of crops, clean air, extreme weather mitigation, and human mental and physical well-being. Collectively, these benefits are becoming known as ecosystem services, and are often integral to the provision of food, the provisioning of clean drinking water, the decomposition of wastes, and the resilience and productivity of food ecosystems.
Prairie restoration is a conservation effort to restore prairie lands that were destroyed due to industrial, agricultural, commercial, or residential development. The primary aim is to return areas and ecosystems to their previous state before their depletion.
An endangered species recovery plan, also known as a species recovery plan, species action plan, species conservation action, or simply recovery plan, is a document describing the current status, threats and intended methods for increasing rare and endangered species population sizes. Recovery plans act as a foundation from which to build a conservation effort to preserve animals which are under threat of extinction. More than 320 species have died out and the world is continuing a rate of 1 species becoming extinct every two years. Climate change is also linked to several issues relating to extinct species and animals' quality of life.
Pleistocene rewilding is the advocacy of the reintroduction of extant Pleistocene megafauna, or the close ecological equivalents of extinct megafauna. It is an extension of the conservation practice of rewilding, which aims to restore functioning, self-sustaining ecosystems through practices that may include species reintroductions.
Wetland conservation is aimed at protecting and preserving areas of land including marshes, swamps, bogs, and fens that are covered by water seasonally or permanently due to a variety of threats from both natural and anthropogenic hazards. Some examples of these hazards include habitat loss, pollution, and invasive species. Wetland vary widely in their salinity levels, climate zones, and surrounding geography and play a crucial role in maintaining biodiversity, ecosystem services, and support human communities. Wetlands cover at least six percent of the Earth and have become a focal issue for conservation due to the ecosystem services they provide. More than three billion people, around half the world's population, obtain their basic water needs from inland freshwater wetlands. They provide essential habitats for fish and various wildlife species, playing a vital role in purifying polluted waters and mitigating the damaging effects of floods and storms. Furthermore, they offer a diverse range of recreational activities, including fishing, hunting, photography, and wildlife observation.
Rewilding is a form of ecological restoration aimed at increasing biodiversity and restoring natural processes. It differs from ecological restoration in that rewilding aspires to reduce human influence on ecosystems. It is also distinct from other forms of restoration in that, while it places emphasis on recovering geographically specific sets of ecological interactions and functions that would have maintained ecosystems prior to human influence, rewilding is open to novel or emerging ecosystems which encompass new species and new interactions.
Pleistocene Park is a nature reserve on the Kolyma River south of Chersky in the Sakha Republic, Russia, in northeastern Siberia, where an attempt is being made to re-create the northern subarctic steppe grassland ecosystem that flourished in the area during the last glacial period.
Stuart Leonard Pimm is the Doris Duke Chair of Conservation Ecology at Duke University. His early career was as a theoretical ecologist but he now specialises in scientific research of biodiversity and conservation biology.
Michelle Nijhuis is an American science journalist who writes about conservation and climate change for many publications, including National Geographic and Smithsonian magazines.
Ecomodernism is an environmental philosophy which argues that technological development can protect nature and improve human wellbeing through eco-economic decoupling, i.e., by separating economic growth from environmental impacts.
Nancy Huntly is an American ecologist based at Utah State University, where she is a Professor in the Department of Biology and director of the USU Ecology Center. Her research has been on biodiversity, herbivory, and long-term human ecology. She started her position at USU in 2011, after serving as a Program Officer in the Division of Environmental Biology at the National Science Foundation. Prior to that she was a faculty member in the Department of Biological Sciences at Idaho State University (Pocatello).
The wood-pasture hypothesis is a scientific hypothesis positing that open and semi-open pastures and wood-pastures formed the predominant type of landscape in post-glacial temperate Europe, rather than the common belief of primeval forests. The hypothesis proposes that such a landscape would be formed and maintained by large wild herbivores. Although others, including landscape ecologist Oliver Rackham, had previously expressed similar ideas, it was the Dutch researcher Frans Vera, who, in his 2000 book Grazing Ecology and Forest History, first developed a comprehensive framework for such ideas and formulated them into a theorem. Vera's proposals, although highly controversial, came at a time when the role grazers played in woodlands was increasingly being reconsidered, and are credited for ushering in a period of increased reassesment and interdisciplinary research in European conservation theory and practice. Although Vera largely focused his research on the European situation, his findings could also be applied to other temperate ecological regions worldwide, especially the broadleaved ones.
The conservation of bison in North America is an ongoing, diverse effort to bring American bison back from the brink of extinction. Plains bison, a subspecies, are a keystone species in the North American Great Plains. Bison are a species of conservation concern in part because they suffered a severe population bottleneck at the end of the 19th century. The near extinction of the species during the 1800s unraveled fundamental ties between bison, grassland ecosystems, and indigenous peoples’ cultures and livelihoods.# English speakers used the word buffalo for this animal when they arrived. Bison was used as the scientific term to distinguish them from the true buffalo. Buffalo is commonly used as it continues to hold cultural significance, particularly for Indigenous people. Recovery began in the late 1800s with a handful of individuals independently saving the last surviving bison.# Dedicated restoration efforts in the 1900s bolstered bison numbers though they still exist in mostly small and isolated populations. Expansion of the understanding of bison ecology and management is ongoing. The contemporary widespread, collaborative effort includes attention to heritage genetics and minimal cattle introgression.#
