Ecological hotspots are areas with outstanding biodiversity or a high concentration of biological values. These values can refer to threatened or endemic species, unique ecosystems, or globally important numbers of a particular species.
What is a hot spot in ecology?
solutions to biodiversity loss
Such “hot spots” are regions of high endemism, meaning that the species found there are not found anywhere else on Earth. Ecological hot spots tend to occur in tropical environments where species richness and biodiversity are much higher than in ecosystems closer to the poles.

What determines/identifies a biodiversity hotspot? It must have at least 1,500 vascular plants as endemics — which is to say, it must have a high percentage of plant life found nowhere else on the planet. A hotspot, in other words, is irreplaceable. It must have 30% or less of its original natural vegetation.

What is in the ecosystem?
An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors include plants, animals, and other organisms.

Most globally significant biodiversity hotspots lie firmly within the tropics or in the Mediterranean climate zones of the world, such as California and the Cape Floristic Region of South Africa.
Which habitat exhibits the greatest biodiversity?
tropical forests
Specifically, biodiversity of land species is greatest in tropical forests and marine diversity is greatest along coral reefs. Therefore, biodiversity is low around the poles of Earth, places that are cold and dry.
How many areas of the world qualify as hot spots?
35 areas
Around the world, 35 areas qualify as hotspots. They represent just 2.3% of Earth’s land surface, but they support more than half of the world’s plant species as endemics — i.e., species found no place else — and nearly 43% of bird, mammal, reptile and amphibian species as endemics.
How does identifying ecological hotspots help maintain biodiversity quizlet?
Biodiversity hotspots are important because it is within these unique ecosystems that many rare and endangered species exist. Therefore, it is important to study and protect these areas. As we have learned, the more diverse (in every sense) the ecosystem, the hardier it is.
How are biodiversity hotspots and endemic species related quizlet?
A: Endemic species are species that are native to and found only within a limited area.
