Biocoenosis
A biocenosis (UK English, biocoenosis, also biocenose, biocoenose, biotic community, biological community, ecological community, life assemblage), coined by Karl Möbius in 1877, describes the interacting organisms living together in a habitat (biotope). Möbius, Karl. 1877. ''Die Auster und die Austernwirtschaft.'' Verlag von Wiegandt, Hemple & Parey: Berlin (English translation: The Oyster and Oyster Farming. ''U.S. Commission Fish and Fisheries Report'', 1880: 683–751) The use of this term has declined in the 21st сentury. In the palaeontological literature, the term distinguishes "life assemblages", which reflect the original living community, living together at one place and time. In other words, it is an assemblage of fossils or a community of specific time, which is different from "death assemblages" ( thanatocoenoses).e.g. Ager, 1963, Principles of Palaeoecology No palaeontological assemblage will ever completely represent the original biological community (i.e. ...

Karl Möbius
Karl August Möbius (7 February 1825 in Eilenburg – 26 April 1908 in Berlin) was a German zoologist who was a pioneer in the field of ecology and a director of the Natural History Museum in Berlin. Early life Möbius was born in Eilenburg in Saxony. At the age of four he attended primary school at the Bergschule Eilenburg, and at the age of 12 he was sent by his father to train as a teacher. In 1844 he passed the exams with distinction and began working as teacher in Seesen, on the northwest edge of the Harz mountain range. In 1849, and encouraged by Alexander von Humboldt, he began studying natural science and philosophy at Natural History Museum of Berlin. After he graduated, he taught from 1853 to 1868 zoology, botany, mineralogy, geography, physics, and chemistry at the Gelehrtenschule des Johanneums in Hamburg. Oysters and ecology In 1863 he opened the first German sea water aquarium, in Hamburg. In 1868, shortly after passing his doctoral examination at the Univers ...

Thanatocoenosis
Thanatocoenosis (from Greek language ''thanatos'' - death and ''koinos'' - common) are all the embedded fossils at a single discovery site. This site may be referred to as a "death assemblage". Such groupings are composed of fossils of organisms which may not have been associated during life, often originating from different habitats. Examples include marine fossils having been brought together by a water current or animal bones having been deposited by a predator. A site containing thanatocoenosis elements can also lose clarity in its faunal history by more recent intruding factors such as burrowing microfauna or stratigraphic disturbances born from anthropogenic methods. This term differs from a related term, biocoenosis, which refers to an assemblage in which all organisms within the community interacted and lived together in the same habitat while alive. A biocoenosis can lead to a thanatocoenosis if disrupted significantly enough to have its dead/fossilized matter scattered. A ...

Community (ecology)
In ecology, a community is a group or association (ecology), association of Population ecology, populations of two or more different species occupying the same geographical area at the same time, also known as a biocoenosis, biotic community, biological community, ecological community, or life assemblage. The term community has a variety of uses. In its simplest form it refers to groups of organisms in a specific place or time, for example, "the fish community of Lake Ontario before industrialization". Community ecology or synecology is the study of the interactions between species in communities on many spatial and temporal scales, including the distribution, structure, abundance, demography, and biological interaction, interactions of coexisting populations. The primary focus of community ecology is on the interactions between populations as determined by specific genotypic and phenotypic characteristics. It is important to understand the origin, maintenance, and consequences ...

Ecosystem
An ecosystem (or ecological system) is a system formed by Organism, organisms in interaction with their Biophysical environment, environment. The Biotic material, biotic and abiotic components are linked together through nutrient cycles and energy flows. Ecosystems are controlled by external and internal Environmental factor, factors. External factors—including climate—control the ecosystem's structure, but are not influenced by it. By contrast, internal factors control and are controlled by ecosystem processes; these include decomposition, the types of species present, root competition, shading, disturbance, and succession. While external factors generally determine which Resource (biology), resource inputs an ecosystem has, their availability within the ecosystem is controlled by internal factors. Ecosystems are wikt:dynamic, dynamic, subject to periodic disturbances and always in the process of recovering from past disturbances. The tendency of an ecosystem to remain clo ...

Ecology
Ecology () is the natural science of the relationships among living organisms and their Natural environment, environment. Ecology considers organisms at the individual, population, community (ecology), community, ecosystem, and biosphere levels. Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history. Ecology is a branch of biology, and is the study of abundance (ecology), abundance, biomass (ecology), biomass, and distribution of organisms in the context of the environment. It encompasses life processes, interactions, and adaptations; movement of materials and energy through living communities; ecological succession, successional development of ecosystems; cooperation, competition, and predation within and between species; and patterns of biodiversity and its effect on ecosystem processes. Ecology has practical applications in fields such as conservation biology, wetland management, natural resource m ...

Biogeography
Biogeography is the study of the species distribution, distribution of species and ecosystems in geography, geographic space and through evolutionary history of life, geological time. Organisms and biological community (ecology), communities often vary in a regular fashion along geographic gradients of latitude, elevation, allopatric speciation, isolation and habitat species-area curve, area. Phytogeography is the branch of biogeography that studies the distribution of plants. Zoogeography is the branch that studies distribution of animals. Mycogeography is the branch that studies distribution of fungi, such as mushrooms. Knowledge of spatial variation in the numbers and types of organisms is as vital to us today as it was to our early human ancestors, as we adapt to heterogeneous but geographically predictable Natural environment, environments. Biogeography is an integrative field of inquiry that unites concepts and information from ecology, evolutionary biology, taxonomy (bio ...

Population Biology
The term population biology has been used with different meanings. In 1971, Edward O. Wilson ''et al''. used the term in the sense of applying mathematical models to population genetics, community ecology, and population dynamics. Alan Hastings used the term in 1997 as the title of his book on the mathematics used in population dynamics. The name was also used for a course given at UC Davis in the late 2010s, which describes it as an interdisciplinary field combining the areas of ecology and evolutionary biology. The course includes mathematics, statistics, ecology, genetics, and systematics Systematics is the study of the diversification of living forms, both past and present, and the relationships among living things through time. Relationships are visualized as evolutionary trees (synonyms: phylogenetic trees, phylogenies). Phy .... Numerous types of organisms are studied. The journal '' Theoretical Population Biology'' is published. See also References External l ...

Hylozoism
Hylozoism is the philosophical doctrine according to which all matter is alive or animated, either in itself or as participating in the action of a superior principle, usually the world-soul (''anima mundi''). The theory holds that matter is unified with life or spiritual activity. The word is a 17th-century term formed from the Greek words ὕλη (''hyle'': "wood, matter") and ζωή (''zoē'': "life"), which was coined by the English Platonist philosopher Ralph Cudworth in 1678. Hylozoism in Ancient Greek Philosophy Hylozoism in Western philosophy can be traced back to ancient Greece. The Milesian philosophers Thales, Anaximander, and Anaximenes, can be described as hylozoists. Philosopher David Skrbina states that hylozoism was implicit in early Greek philosophy, and was not a doctrine that was typically challenged. "For the Milesians, matter (''hyle'') possessed life (''zoe'') as an essential quality. Something like hylozoism was simply accepted as a brute cond ...

Environment Protection And Biodiversity Conservation Act 1999
The ''Environment Protection and Biodiversity Conservation Act 1999'' (Cth) is an Act of the Parliament of Australia that provides a framework for protection of the Australian environment, including its biodiversity and its natural and culturally significant places. Enacted on 16 July 2000, it established a range of processes to help protect and promote the recovery of threatened species and ecological communities, and preserve significant places from decline. The Act is administered by the Department of Climate Change, Energy, the Environment and Water. Lists of threatened species are drawn up under the Act, and these lists, the primary reference to threatened species in Australia, are available online through the Species Profile and Threats Database (SPRAT). As an Act of the Australian Parliament, it relies for its constitutional validity upon the legislative powers of the Parliament granted by the Australian Constitution, and key provisions of the Act are largely ba ...
