Learn something new everyday

I'll admit it. When I think "invasive species" I think "eminent threat." Guilty. I mean... hello?? Zebra Mussels?? It was decades ago (1986) but few have forgotten about the stowaways in the ballast tanks of ocean vessels that reproduced uncontrollably clogging pipes and waterways.

Good news about some species in New Zealand though - reported by Carl Zimmer in the NY Times. Not all biological invasions are created equal. Read a bit of the debate about the softer side of invasive species: the naturalized species and hybrids, the evolution and diversification versus the potential "infestations," extinction, climate change and habitat loss in Zimmer's article here
