Before we can even contemplate trying to maintain or even increase the biodiversity of a habitat we need to know what species are present i.e. we need to give them a name. Without taxonomy that would not be possible.

A2 students will be looking at these ideas this week in lessons. For those people keen to get a head start have a look at the Natural History Museum Web Site. It gives you the background to the topic and information on Linnaeus‘ role in every species having a name in two parts.

Tripping over Psychoactive Toads October 13, 2009

For anyone fresh out of frogs and tempted to kiss a toad instead, this article has a word of warning.
