Compare this map with the global map of the human ecological footprint, shown in Figure 1.8. Biodiversity includes diversity within species (genetic diversity), between species (species diversity), and between ecosystems (ecosystem diversity). islands, tropical rain forests, and coastal areas. ... hotspots are critical … ... [16][17]. Where are biodiversity hotspots located? Biodiversity Hotspots are biogeographic regions that have the richest and the most threatened reservoirs of plant and animal life on earth. Asian Pacific. islands, tropic rain forests, and coastal areas. The 36 biodiversity hotspots are home to around 2 billion people, including some of the world's poorest, many of whom rely directly on healthy ecosystems for their livelihood and well-being. Accordingly, 34 biodiversity hotspots have been so far identified. To qualify as a hotspot, a region must meet two strict criteria: Endemism: it must contain at least 1,500 species of vascular plants (> 0.5 percent of the world’s total) as endemics, and Loss of Habitat: it has to have lost at least 70 percent of its original habitat. The hotspots represent an opportunity to help conserve the diversity of life on earth. These also comprise of around 50% of the world's most common plant species and 42% of terrestrial vertebrates prevalent. d. All of the above . Biodiversity is a contraction of biological diversity. The Conservancy's project is located in a biodiversity hotspot convergence zone—where the coastal forests of Eastern Africa and Horn of Africa meet. But biodiversity is declining and many of the world’s greatest biodiversity hotspots are located in countries burdened by poverty, food insecurity, and intensifying climate change. Where are many critical biodiversity hotspots located? desert and polar environments. BIODIVERSITY HOTSPOT A biodiversity hotspot is a biogeographic region that is both a significant reservoir of biodiversity and is threatened with destruction. Biodiversity refers to the variety of living species on Earth, including plants, animals, bacteria, and fungi. Biodiversity is a measure of ecological health (Johnson 554). Plants, animals, and other living organisms that populate these places are rare and many of them are only found in these specific geographic areas. Hotspots are regions characterized by numerous endemic plant and animal species living in a particularly vulnerable environment. While Earth’s biodiversity is so rich that many species have yet to be discovered, many species are being threatened with extinction due to human activities, putting the Earth’s magnificent biodiversity at risk. Protecting Biodiversity Hotspots (2 of 2) Figure 10.26: Endangered natural capital.Biologists have identified these 34 biodiversity hotspots. Half of them are located in mountain regions. deserted and polar environments. SURVEY . Eastern Afromontane . Concept was first introduced by Norman Myers , in a paper published in the journal Nature. More than 35 biodiversity hotspots have been identified around the world. The ten regions identified all intersect with global Biodiversity Hotspots and cover 13-percent of currently cultivated land in the tropics and 7 … Tags: Question 25 . The country is located in biogeographic crossroad between Palaearctic and Afro-tropical ecoregions [18] and mountains disrupt the latitudinal gradient in climate and habitat of the region [19]. Biodiversity Estimation of Earth. How can zoos, botanic gardens, and wildlife parks help save species? Almost 2.3% of the land surface of Earth is represented by these hotspots. Coral reefs are believed by many to have the highest biodiversity of any ecosystem on the planet—even more than a tropical rainforest. 29. We will discuss the biodiversity distribution in the four hotspots of India. These biodiversity hotspots are currently at risk of being destroyed . To qualify as a biodiversity hotspot on Myers 2000 edition of the hotspot-map, a region must meet two strict criteria: India is one of the mega biodiversity centres in the world and has two of the world's 18 'biodiversity hotspots' located in the Western Ghats and in … Chen (1998), using estimated species richness and number of endemics, proposed 11 terrestrial critical regions for the conservation of China's biodiversity, eight of which were located within the hotspot ecoregions identified in this study. All of the above. Where are many critical biodiversity hotspots located? As many as 44% of all species of vascular plants and 35% of all species in four vertebrate groups are confined to 25 hotspots comprising only … cities and developed areas of the world. Biodiversity hotspots are defined as regions where exceptional concentrations of endemic species are undergoing an exceptional loss of habitat. There are at least 7,600 plant species including 2,350 endemic species. answer choices . Overlooked Mountain Rock Pools in Deserts Are Critical Local Hotspots of Biodiversity. SURVEY . From lush rainforests to majestic mountains, some regions of Earth are simply irreplaceable. Consequently, these regions are recognized as biodiversity hotspots (Médail & Quézel, 1997 Myers et al., 2000), which include interesting patterns and processes in … Today, there are 35 biodiversity hotspots that have been identified around the world [2]. Biodiversity hotspots can include a variety of human land-uses, rural and urban, as well as protected areas under a range of possible governance types therefore many social and/or cultural values are likely to be present in some parts. There are 36 biodiversity hotspots on our planet, and these areas are dazzling, unique, and full of life. Q. In. a. by preserving threatened species from destruction. all of the above. One of the biggest reasons that biodiversity hotspots are being destroyed is because of human activities like farming because regions are being deforested to make room for subsistence farming. Biodiversity hotspots. The hotspots provide crucial ecosystem services for human life, such as provision of clean water, pollination and climate regulation. The Guinean forests house a great diversity of flora and fauna including many endemic species. Biodiversity Hotspots of India. Question: Why do you think so many hotspots are located near coastal areas? Although they only make up less than 2.5% of land surface, a large portion of the species in these zones are only found in that particular region [1,2]. Home / Coral Reefs 101 / Coral Reef Ecology / Coral Reef Biodiversity Coral Reef Biodiversity Biodiversity is the variety of living species that can be found in a particular place—region, ecosystem, planet, etc. answer choices . Biodiversity and viable ecosystems protect us from natural disasters, regulate the climate, and provide food, fertile soil, and medicine. By now, a total of 35 biodiversity hotspots have been identified out of which most of them lie in tropical forests. On average, 30.2% of ecosystem service hotspots are located within terrestrial critical biodiversity areas, 51.1% within D’MOSS, with nominal overlaps of 0.3%, 3.9% and 5.1% within estuaries and freshwater critical biodiversity areas and conservation areas, respectively (Table 2). In the year 2000, scientists writing in the journal Nature identified 25 biodiversity hotspots that cover only about 1.4% of the Earth's surface, or an area of approximately 2.1 million square kilometers. Q. Where are many critical biodiversity hotspots located? Coming back home, India is one of the top mega-diverse countries in the world. It reflects the number, variety and variability of living organisms and how these change from one location to another and over time. A biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is threatened by human habitation.. Norman Myers wrote about the concept in two articles in “The Environmentalist” (1988), and 1990 revised after thorough analysis by Myers and others “Hotspots: Earth’s Biologically Richest and Most Endangered Terrestrial Ecoregions” and a … 36 ecological hotspots in the world fulfill this criteria and are included in Myer’s list.. Here’s a map that shows distribution of those Global Biodiversity Hotpsots. A biodiversity hotspot is the richness and variety of species in a region. b. islands, tropical rain forests, and coastal areas.
