Summary

Habitat is a term used in ecology to describe the resources, physical, and biotic factors present in an area to support the survival and reproduction of a particular species. Every species has specific habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions, while habitat specialist species require a limited set of factors to survive. Habitat types are environmental categorizations of different environments based on the characteristics of a given geographical area, particularly vegetation and climate. Terrestrial habitat types include forests, grasslands, wetlands, and deserts, and freshwater habitat types include rivers, streams, lakes, ponds, marshes, and bogs. Marine habitats include brackish water, estuaries, bays, the open sea, the intertidal zone, the sea bed, reefs, and deep and shallow water zones. Urban environments have also become habitats for many animals and plants. A microhabitat is the small-scale physical requirements of a particular organism or population, and every habitat includes large numbers of microhabitat types with subtly different exposure to light, humidity, temperature, air movement, and other factors. Some organisms have managed to colonize extreme environments that are unsuitable for more complex life forms, such as bacteria living in Lake Whillans half a mile below the ice of Antarctica, and microbes living in environments lacking in oxygen, dependent on chemical reactions other than photosynthesis.Habitat Types: Examples and Importance

  • Animals living at great depths are adapted to high pressure environments by having pressure-resistant biomolecules and small organic molecules present in their cells.
  • Hydrothermal vents support unique communities of organisms in their immediate vicinity through the process of chemosynthesis.
  • The airborne microbial community may be as diverse as that found in soil or other terrestrial environments.
  • Loss of habitat is the single greatest threat to any species.
  • Habitat fragmentation can be ameliorated to some extent by the provision of wildlife corridors connecting the fragments.
  • Habitat disturbance can have long-lasting effects on the environment.
  • Protection of habitat types is a necessary step in the maintenance of biodiversity.
  • Even where legislation protects the environment, a lack of enforcement often prevents effective protection.
  • A monotypic habitat-type is a concept sometimes used in conservation biology, in which a single species of animal or plant is the only species of its type to be found in a specific habitat and forms a monoculture.
  • Some invasive species may create monocultural stands that prevent other species from growing there.
  • The yellow starthistle, Centaurea solstitialis, is a botanical monotypic habitat example that currently dominates over 15,000,000 acres (61,000 km2) in California alone.
  • The non-native freshwater zebra mussel, Dreissena polymorpha, that colonizes areas of the Great Lakes and the Mississippi River watershed, is a zoological monotypic habitat example.
