The trophic role of the squid Loligo plei as a keystone species in the South Brazil Bight ecosystem
(OXFORD UNIV PRESS, 2010)
The issue of whether loliginid squid can influence the average structure of marine ecosystems in a keystone role, i.e. a strong effect with relatively low biomass, has not yet been examined. Here, the diet of Loligo plei ...

Pogonomyrmexcunicularius as the keystone disperser of elaiosome-bearing Jatropha excisa seeds in semi-arid Argentina
(Wiley Blackwell Publishing, Inc, 2011-05)
