Population Size. Biodiversity hot spots have a high number of endemic species(species that occur nowhere else). Primary succession can occur, for example, following the eruption of volcanoes such as those on Hawaii's Big Island. Some species do really well after a disturbance, they are called: Primary successional species WWF works to sustain the natural world for the benefit of people and wildlife, collaborating with partners from local to global levels in nearly 100 countries. Those terms can include species that are at low populations and near extinction but still not legally protected under ESA. Which of the following is an example of pollution? A perfect example for this would be rock formations into the ocean after a volcanic eruption. The extent and quality of its forest habitat are in decline. Saving this habitat also benefits other species, Flagship species are especially interesting or attractive organisms to which people react emotionally. Human beings are a species of least concern, along with most domestic animals, such as dogs and cats. Until 2000, black soft-shell turtles lived throughout the wetlands of the Brahmaputra River, feeding mostly on freshwater fish.Unlike other animals that are extinct in the wild, black soft-shell turtles are not found in many zoos. They have healthy populations, but their rain forest habitat is disappearing at a fast pace. Probably vulnerable but definitely not near threatened 2. Compare it to fossil fuels by explaining two pros and two cons for its implementation on a large scale.Maintain an environmental focus (do not just give economic reasons). 3) Population sizeSpecies with fewer than 10,000 mature individuals are vulnerable.
