Question

What types of species are most vulnerable to extinction and what kinds of factors threaten them?

Answer 1

· Species with a narrow geographic range: like mountain tops, valleys, islands

· Niche species: once their niche is lost they quickly disappear

· Species adapted to stable environments: like the shade of the canopy

· Endemic (especially island) species: easily decimated by introduced species  

· Species with naturally small, dispersed populations

· Species with few populations

· Species with poor dispersal: species that need specific pollinators or dispersers

· Species with low reproduction rates: gorillas, indri lemurs, harpy eagles, etc.

· Ecologically naive species: species that have been isolated and have no natural predators  

· Species with a large body size

· Migratory species

· Predatory species

· Species that are used (hunted, harvested, or killed) by humans

Endangered species are threatened by factors such as habitat loss, hunting, disease and climate change, and usually, endangered species, have a declining population or a very limited range.
