What is endemic species?
Before focusing on endemic species, let’s look at the definition of endemism. Endemism is a term used in biology to talk about the distribution of a taxon limited to a small geographic area and which can therefore be found naturally in this place. In consequence, endemic species are those that live in a limited area, such as a mountain range, lake, or island, among others. Therefore, the ecological aspect of the place and the biological characteristics of living beings influence this condition.
Endemic species are crucial to the health of our planet because of the enormous variety of living beings they contribute to the environment. In fact, it is no coincidence that megadiverse countries, those that are home to at least 70 % of the planet’s terrestrial biological diversity account for only around 10 % of the surface but are home to a massive number of endemic species.
Endemic species are the most vulnerable of all and, therefore, those in the greatest danger of extinction, which can be due to natural causes or human activity. As well as the consequences of climate change, there are other threats, such as poaching, changing habitats, and the introduction of invasive species. What’s more, environmental conservation has become a major standard-bearer for protecting these species.
What types of endemism
Endemic species can be classified in two ways, by their geographical distribution or genetics, giving rise to a series of categories:
- Microendemic species: are those established in a limited area.
- Quasi-endemic: species that go beyond the limits of their specific zone.
- Semi-endemic: species that spend only part of the year in a specific area.
- Paleo-endemics: are species that eventually form isolated groups due to their morphological, chemical, or genetic characteristics.
- Schizo-endemics: are species formed by gradual isolation but which have similar chromosomic and morphological characteristics.
- Patro-endemics: are species that emerge due to changes in the number of chromosomes and which colonize more extensive areas than their predecessors.
- Apo-endemics: these are species that derive from others and which, unlike patro-endemic species, occupy smaller areas than their predecessors.
What is Vietnam’s endemic species?
Vietnam is included in the Indo-Burma biodiversity hotspot (Biodiversity Hotspots WM). The Annamite Forests (Wonders of the Annamites) are especially notable for endemic species. The Mekong River (ResearchGate) has one of the world’s richest freshwater faunas.
