Document Summary
*this lecture focuses on applied side of evolutionary biology: the societal concerns. The problem of invasive species: lantana camara is native to central america (grown often in gardens), introduced to the british by india. Introducing it to the big lakes resulted in the extinction of numerous endemic cichlid fish species: they thought introducing this fish would increase fishe(cid:396)ies (cid:271)ut (cid:373)ost af(cid:396)i(cid:272)a(cid:374)s do(cid:374)"t fi(cid:374)d this fish particularly tasty. Asian carp invasion: carp is an invasive species from asia that is a major aquatic threat in the great lakes, estimated that million was spent in 2010 to prevent the invasion.
