This weekend in invasive species blogging:
- The Botany Photo of the Day for Saturday is Orbea variegata, an invasive species in Australia. So pretty! :-)
- Did introduced rats and chickens cause the downfall of Rapa Nui? Daniel Drezner, The Volokh Conspiracy and others are blogging about Terry Hunt's essay in American Scientist that questions Jared Diamond's supposition of tree-felling as one of the major causes.
- piranha's nest has got some cringe-inducing shots of European wasp nests...in Canada.
- johnatnocorners blogs about Himalayan balsam - nice photos John!
