In ecological studies, biocoenosis is the emphasis on relationships between species in an area.

The association is a conceptual model of a concrete phytocoenosis (the plant component of a biocoenosis).

However, with environmentalists warning that the island's biocoenosis has been overly affected, a new population of 60 hares and 100 pheasants was introduced into the ecosystem in 2006.

Several authors recognized at the time that species were not independent of each other, and grouped them into plant species, animal species, and later into communities of living beings or biocoenosis.

A biocoenosis (biocoenose, biocenose, biotic community, biological community, ecological community), coined by Karl Möbius in 1877, describes the interacting organisms living together in a habitat (biotope).

For modern ecologists, ecology can be studied at several levels: population level (individuals of the same species in the same or similar environment), biocoenosis level (or community of species), ecosystem level, and biosphere level.

It is different from biophysics in having the necessity of taking into account the specific features of biotope and biocoenosis, which involves the knowledge of nutritional science and agroecology, agricultural technology, biotechnology, genetics etc.

It was in 1935 that Arthur Tansley, the British ecologist, coined the term ecosystem, the interactive system established between the biocoenosis (the group of living creatures), and their biotope, the environment in which they live.

Agrophysics is a branch of science bordering on agronomy and physics, whose objects of study are the agroecosystem - the biological objects, biotope and biocoenosis affected by human activity, studied and described using the methods of physical sciences.

Other historically important work sought to provide biotic indices for classifying waters according to the biotic communities that they supported.

Hawley writes "thus the development of human dominance through the agency of culture involves a reconstruction of the biotic community.

Instead of accommodating his activities, as do primitive peoples, to the natural life association, civilized man regulates the biotic community in accordance with his needs".

"Sea level rise will cause a change of state from freshwater to marine or estuarine ecosystems, radically altering the composition of biotic communities".

In regards to the biotic communities of the Great Plains, the potential repercussions of these changes could be felt in a variety of ways.

Ecocentrism focuses on the biotic community as a whole and strives to maintain ecosystem composition and ecological processes.

An explicit statement of what is now called the concept of a biotic community was made in Karl Möbius' study of oyster beds (1877).

Biotic communities that are essential components of marine ecological system such as coral and sea grasses can be observed in the coastal waters of the island.

Their biotic communities are restricted to aquatic wetland and riparian zones within Arizona, with a more restricted elevation distribution of 609 to 2060 meters.

They have a stricter range in elevation, being found only in rivers between 2600 and 5600 feet, and they are restricted to Riparian biotic communities.

The coral community is really a system that includes a collection of biological communities, representing one of the most diverse ecosystems in the world.

Microbiologists and biophysicists have largely adopted this definition, leading to some conflict in the biological community over an issue of language.

Thus, many biological communities may be made up of organisms that despite their complex biological interactions have very little evolutionary history with each other.

It affects oceans, flooding, and biological communities.

Many undesirable changes in the structure of biological communities have resulted, and some important species have either declined or completely disappeared.
