1996 provide additional examples of possible keystone species in freshwater systems that include beaver Castor canadensis and their effect on streams predatory fish in river and stream food webs piscivorous fish in the trophic cascade of lakes predatory salamanders in temporary ponds that prey on anuran tadpoles and planktivorous fish that have strong impacts on zooplankton communities. Mangrove trees for instance serve a keystone role in many coastlines by firming up shorelines and reducing erosion. 16 In areas in which sea otters are abundant the kelp communities are diverse and healthy because of.
