The habitat ( word origin from Latin habitare ' to live' ), in German mostly translated as habitat , describes in biology the characteristic habitat of a certain animal or plant species or the habitat determined by specific abiotic and biotic factors in which the species is in a stage lives its life cycle.

The term habitat was originally used only in an autecological sense , i.e. based on one species. In English-language literature (and now occasionally in German-language texts) it is also used in a synecological context, synonymous with biotope , so that the place where a community lives is also referred to as habitat. Campbell and Reece define a habitat as a spatially delimitable part of a biotope. The term is also used in other sciences. In botany, especially vegetation ecology, the term location is usually used instead of habitat in the auto-ecological sense .

Habitat of animals and plants

According to Campbell and Reece (2009), a habitat is understood to be the habitat used by a selection of animal or plant species from the community of a biotope. Habitats thus form partial habitats in biotopes. The selection is often limited to a few species or one species, such as “habitat of a species”. Depending on the type and time of use, a distinction is made between foraging, spawning, breeding and nesting habitats or between summer and winter habitats.

Very small or specially demarcated habitats are called microhabitats . Habitats that mark the preferred habitat of a species are also called preferred habitats, biochorions or choriotopes . They are usually given for larger, heterogeneously structured biotopes. Extremophile species settle in extreme habitats , in habitats with extreme environmental conditions.

If the entire habitat of an individual or a population comprises several differently structured areas, we speak of complementary or partial habitats. They can be determined primarily for mobile, migratory species such as fish or migratory birds and can also be located in separate biotopes. Partial habitats can be found for all animals whose habitats can be divided into functional spaces, for example for feeding, reproducing or retreating.

In connection with (especially huntable) wild animals, habitat or colloquially, habitat is common. Such habitats form protection, cover or resting zones. The fish fauna, for example, needs habitat on or after exhausting long-distance hikes.

Fauna-flora habitat

The terms Fauna-Flora-Habitat and FFH-Area are used colloquially abbreviated and unspecifically for areas of community importance, i.e. areas according to Directive 92/43 / EEC (Fauna-Flora-Habitat Directive) . This refers to habitats of mostly individual species that have been or will be included in the European Natura 2000 system of protected areas for the purpose of species conservation .

Habitat specificity

The degree of dependence on a particular habitat is called habitat specificity . In the case of parasites, for example, this describes their dependence on certain body regions on or in the host organism.

To the origin of the word

The widespread use of the term habitat in biology goes back to the naturalist Carl von Linné , who in his work Species Plantarum published in 1753 always introduced the sentence or paragraph on the habitat of the species in his Latin-language descriptions of the species with italicised habitat in ... 'Lives in ... ' (Emphasis on the first syllable, hence for example Spanish hábitat ). This practice was retained in later species descriptions.

To the change of meaning

Both in German and in other languages ​​- such as French and Spanish - the term is originally only used in an auto-ecological way, i.e. each habitat is a habitat of a species . The use in a synecological context, up to the synonym for biotope , is mainly due to the influence from the English-speaking area.

Human habitat

In anthropology Habitat commonly referred to as a dwelling place like a house or tent or even a settlement of the people , as living space , town , agglomeration or landscape typical form of housing, or a settlement area as one used by a certain population group as a living room area . A dwelling station on another celestial body in space is also called a habitat. In this sense, human habitats are examined by settlement geography and macrosociology .
