Keystone Species

Keystone Species Image
Agnes Lewis 20-30 minutes Some species have a larger-than-most impact on their ecological niches – these are the Keystone species  -- if they disappear, a whole ecological system suffers.  What are some of these species, and how are they likely to hold up over the next hundred years?  What happens if an important species is hated or feared (like sharks?)  How do we know when a species is particularly important?  How are currently identified keystone species doing?
