The number of new calves born in recent years has been below average. Laws may limit hunting and destruction of the species habitat. Biologists say that during the last ice age, cheetahs went through a long period of inbreeding. This technique is also called:Focusing on hot spots. Probably Vulnerable but definitely NOT "near threatened" One way to try to protect species is to focus on areas with high species diversity. Cheetahs (Acinonyx jubatus) are a species of cat best known for being the fastest land animal, with the ability to sprint at speeds of up to 120 kilometers per hour (75 miles per hour) and accelerate to 97 kilometers per hour (60 miles per hour) in as little as three seconds, making them faster than most sports cars.

No, salmon are not endangered worldwide. What is gap analysis, and how is it related to ecosystem management and design of nature preserves? As development and invasive species such as Miconia destroy the bamboo forests, the population of Tahiti reed-warblers continues to shrink. Convention on Biological DiversityThe Convention on Biological Diversity is an international treaty to sustain and protect the diversity of life on Earth. Polar bears, mountain lions, and alligators are all predators brought into close contact with people as they lose their habitat to homes, farms, and businesses. They are called: Secondary successional species Which species example is least likely to become endangered?
