Endemic species: importance, conservation and types of endemism

  • Endemic species are unique to specific geographic areas and are often highly adapted to their environment.
  • They are vulnerable to extinction due to their limited distribution and threats such as climate change and invasive species.
  • Conserving these species is vital to maintaining ecological balance and biodiversity both locally and globally.

importance of endemic species

The endemic species Endemic species are organisms that are only found in a specific geographic region, making them unique and vital to biodiversity. These organisms are not naturally present anywhere else in the world, making their conservation a priority. Throughout this article, we will explore in detail what endemic species are, their characteristics, their distribution area, the types of endemism, and the importance of their conservation to maintain the balance of ecosystems. We will also compare the differences between endemic, native, and exotic species.

What are endemic species?

In biology, the term endemic refers to the limited geographic distribution of a species, meaning that it is only found in a specific area. This phenomenon is the result of evolution and factors such as Geographical separation, climate change and the emergence of physical barriers that prevent species from dispersing outside their original range. Well-known examples include the Panda bear in China and the Kiwi in New Zealand, both adapted to their local environment and with characteristics not seen elsewhere.

Endemic species often inhabit regions that have been isolated for long periods, such as islands, mountains or valleys. As they adapt to the particular conditions of their unique environment, these species develop Unique features that are not found in other world populations, which adds additional value to their conservation.

The status of endemic species can be determined by various natural and human pressures. In many cases, humans have altered their habitats, introducing invasive species, and increasing the risks of extinction. For example, climate change and deforestation threaten many endemic species by destroying or altering the habitats in which they live.

Distribution area of ​​endemic species

different endemic species

The distribution area of ​​an endemic species covers the geographic area where it is found naturally. This area is usually limited due to natural barriers such as rivers, mountains or seas that prevent the species from dispersing to other regions. For this reason, islands tend to concentrate a large number of endemic species, since they are geographically isolated and their ecosystems evolve independently.

Endemism refers to the exclusivity of a species to a region. Endemic species are fundamental to the biological diversity of the planet. Due to their limited distribution, these species are extremely rare. vulnerable to environmental changes, so any alteration to their habitat, such as the introduction of invasive species or climate change, can have devastating effects.

Some areas especially rich in endemisms include the Galapagos Islands, Madagascar, and the tropical regions of South America and Africa. These areas, known as biodiversity hotspots, contain a great diversity of species that do not exist elsewhere and face high rates of threat from human activity.

Differences between endemic, native and exotic species

While all endemic species are also native speciesNot all native species are endemic, and it is important to know the difference. Native species are those that occur naturally in a region, but do not have a limited distribution as endemic species do. For example, a native species may exist in multiple regions due to its ability to disperse or adapt to different conditions.

On the other hand, exotic species o invasive Invasive species are species that have been introduced into a new ecosystem, usually through human activity, and can displace native or endemic species. In many cases, invasive species have no natural predators in their new environment, which allows them to multiply rapidly and change the dynamics of the entire ecosystem.

types of endemism

There are different ways to classify endemism according to the territorial distribution and evolutionary history of the species. These categories help to better understand the factors that contribute to endemism and the vulnerability of the affected species.

According to its territorial distribution:

  • Microendemism: It applies when a species has an extremely limited distribution area, which can be as small as a cave or a specific mountain.
  • Quasi-endemism: When the distribution range of a species extends slightly beyond the established limits, due to the continuity of ecosystems or habitats.
  • Semi-endemism: It refers to a species that is endemic to a region only at certain times of the year, such as migratory birds.

According to its evolutionary history:

  • Paleoendemism: It refers to species that in the past had a wider distribution, but whose range has been considerably reduced by factors such as climate change or habitat fragmentation.
  • Neoendemism: They are more recent species, in evolutionary terms, that are limited to small geographic areas, but that could still expand.

These categories underscore the importance of protecting local habitats, as even a small disturbance could lead to the extinction of species that cannot survive outside their natural environment.

Importance of conserving endemic species

Importance of endemic species and their conservation

The conservation of endemic species is crucial for the balance of ecosystems, as many of these species play unique roles within their environment. In many cases, endemic species are essential pollinators, key predators or prey, or help maintain the structure of ecosystems by controlling other species.

Your loss may have a waterfall effect negative, affecting other species and altering the entire dynamics of the ecosystem. An example would be the disappearance of a pollinator, which could lead to a decrease in the reproduction of native plants, in turn affecting herbivores that depend on those plants for food.

In addition to their ecological value, endemic species possess unique genetic characteristics, developed as adaptations to their local environments. These traits are valuable for scientific research and may have applications in fields such as medicine and biotechnology.

Conservation of endemic species also has aesthetic and cultural value. Many endemic species are emblematic and play an important role in the identity of local communities. For example, the Iberian lynx It is a symbol of wildlife in Spain. Protecting these species also helps preserve the natural and cultural heritage of a region.

It is important to remember that the conservation of endemic species not only benefits local ecosystems, but also contributes to the global biodiversityThe loss of an endemic species represents an irreversible loss in the richness of life on Earth.

In many cases, the creation of protected areas, the restoration of habitats and the elimination of invasive species are important measures to ensure the survival of endemic species.

Understanding and protecting endemic species is key not only to conserving local biodiversity, but also to maintaining the balance of ecosystems globally. Each endemic species represents a unique evolutionary story, and their conservation ensures that we can continue to learn from the extraordinary life that inhabits our planet.
