What is endemic distribution?

What is endemic distribution?

Endemism is the condition of being endemic, or restricted in geographical distribution to an area or region. The area or region can vary in size, and is defined or identified in different ways. Endemism is an ecological classification in that it describes the range or distribution of a species, or group of species.

What are the causes of endemism in India?

Factors responsible for the production of endemics are Natural crossing among the closely related plants growing under favourable conditions and Mutations. If the condition of isolation is developed the effect become more pronounced. Endemism is found in isolated e.g., islands, isolated areas etc.

How do you know if a species is endemic?

In ecology, an endemic species refers to a species that is native to where it is found. A species can be endemic to a particular small geographical area, such as a single island, or to a larger area, such as a continent. If it is found elsewhere, then, endemic is not the word to describe it.

What is endemic and examples?

What is an Endemic? An endemic is a disease outbreak that is consistently present but limited to a particular region. This makes the disease spread and rates predictable. Malaria, for example, is considered an endemic in certain countries and regions.

What is endemism examples?

Endemic species are plant and animal species that are found in a particular geographical region and nowhere else in the world. Some species are endemic to a continent while the others can be endemic to an island. E.g., Lemurs of Madagascar and Tortoises of Galapagos.

Which disease is epidemic?

An epidemic refers to an increase, often sudden, in the number of cases of an infectious disease above what is normally expected in a given population in a specific area. Examples of major epidemics include cholera and diarrhoeal diseases, measles, malaria, and dengue fever.

What are the causes of epidemic?

Epidemics of infectious disease are generally caused by several factors including a change in the ecology of the host population (e.g., increased stress or increase in the density of a vector species), a genetic change in the pathogen reservoir or the introduction of an emerging pathogen to a host population (by …

Where is endemism most likely to be found?

Endemism is found in isolated e.g., islands, isolated areas etc. According the Wulff 85% of Flora of St. ha^ie, 80% of Hawaii islands and 72% of New Zealand is endemic.

What is the difference between endemic and hyperendemic?

Endemic refers to the constant presence and/or usual prevalence of a disease or infectious agent in a population within a geographic area. Hyperendemic refers to persistent, high levels of disease occurrence. Occasionally, the amount of disease in a community rises above the expected level. Epidemic refers to an increase, often sudden, in …

Why are endemic species at risk of destruction?

Because of the area of expertise and inability to move into new habitats, some endemic species are at particular risk of destruction when a new disease hits, when the habitats quality is threatened, or if an invasive species enters its region and becomes a competitor or predator.

When does the local conditions induce reactivation of palaeoendemics?

If the local conditions induce reactivation of Palaeoendemics evolving new endemic species after a long gap they are called active epibiotics. The degree of isolation of the area involved is usually proportional to the percentage of endemic species in flora.

What’s the difference between a stenoendemic and an endemic?

Stenoendemics, also known as local endemics, have a reduced distribution and are synonymous with the word ‘endemics’ in the traditional sense, whereas euryendemics have a larger distribution -both these have distributions which are more or less continuous. A rhoendemic has a disjunct distribution.
