An endemic species is one whose habitat is restricted to a particular area. The term could refer to an animal, a plant, a fungus, or even a microorganism. The definition differs from “indigenous,” or “native,” species in that the latter, although it occurs naturally in an area, is also found in other areas.
What species are restricted to an area?
The species which are confined to a given region or restricted to a given area are called endermic species .
Which term is used for a species which is restricted to a particular area?
Species that are restricted to a particular geographical area are called endemic species .
What is the term used for native organisms that have a restricted distribution?
Endemic species – A species native and confined to a certain region; having comparatively restricted distribution.
What is hotspot region?
A biodiversity hotspot is a biogeographic region that is both a significant reservoir of biodiversity and is threatened with destruction . The term biodiversity hotspot specifically refers to 25 biologically rich areas around the world that have lost at least 70 percent of their original habitat.
What do you understand by the term endemic species?
Any species whose range is restricted to a limited geographical area .
Which one of the following is an example of ex situ conservation?
Zoos, botanical gardens and seed banks are all example of ex-situ conservation.
Which one is an extinct species?
One thing we do know: The western black rhinoceros, the Tasmanian tiger , and the woolly mammoth are among the creatures whose populations at one point dwindled to zero, and it’s possible that species extinction is happening a thousand times more quickly because of humans.
Which is an example of ex situ conservation?
Complete answer: Ex situ conservation is the conservation of areas outside their natural habitat. Botanical gardens, zoological parks, seed banks, cryopreservation, field gene banks , etc. are examples of it.
What are examples of endemic species?
- Hood Lava Lizard (Microlophus delanonis) endemic to Punta Suarez, Española Island Galapagos.
- Red squirrel population which is endemic to the North of Scotland.
- Manx cat found only in the Isle of Man.
- Lemur in Madagascar.
- Sinarapan fish in the Philippines.

What is the endemics area relationship?
Endemics–Area Relationships (EARs) are fundamental in theoretical and applied biogeography for understanding distribution patterns and promoting biodiversity conservation . ... From the models, we calculated the average area needed to harbour a single endemic species as 12,875 km 2 (range 9675–20,529).
What are the example of exotic species?
In addition to dreissenids, examples of competitive effects of exotics on native species include fish (e.g., effects of brown trout on galaxiids in New Zealand streams), crustaceans (e.g., effects of exotic crayfishes on native crayfishes around the world), and macrophytes (e.g., effects of water hyacinth Eichornia on ...
What is the most famous hotspot?
Major hot spots include the Iceland hot spot , under the island of Iceland in the North Atlantic; the Réunion hot spot, under the island of Réunion in the Indian Ocean; and the Afar hot spot, located under northeastern Ethiopia. Volcanic activity at hot spots can create submarine mountains known as seamounts.
What are the 4 types of biodiversity?
- Species Diversity. Every ecosystem contains a unique collection of species, all interacting with each other. ...
- Genetic Diversity. Genetic diversity describes how closely related the members of one species are in a given ecosystem. ...
- Ecosystem Diversity. ...
- Functional Diversity.
How many hotspots are there?
To be classified as a biodiversity hotspot, a region must have lost at least 70 percent of its original natural vegetation, usually due to human activity. There are over 30 recognized biodiversity hotspots in the world.
