The autumn meeting of the London Freshwater Group was held on the afternoon of 2nd November 2007 at the Natural History Museum. A fantastic turn out of at least 80 participants, including a high proportion of young freshwater ecologists listened to talks criss-crossing a range of topics. Dave Williams (NHM) gave a fascinating talk on the origins of diatom species in Lake Baikal and warming to the diatom theme Helen Bennion (Geography, UCL) followed up with a comprehensive account of how palaeolimnology is being used in connection with the EU Water Framework Directive. Angela Gurnell (Geography, Kings College) then gave as good a demonstration of the need for integrated geomorphological-hydrological-ecological studies as I have ever seen with a talk on the role of trees (both dead and alive) for hydrogeomorphic processes on the Tagliamento floodplain, Italy. After coffee Suzanne McGowan (Geography, Nottingham) gave an interesting talk on her collaborative work comparing fossil pigment data with long-term phytoplankton records for Lake Windermere and was followed by Jenny Shmid-Araya (Biology, QMUL) who provided us with much food for thought on how well we have so far characterised stream food webs. Of course the Broadstone stream was high on the agenda here. All speakers received several questions from a lively audience and the lively nature of the afternoon continued into a well attended and lively session in the pub! The next LFG meeting with be on Friday March 14th 2008 (2 pm), most likely at the Linnean Society of London. Please do contact me if you would like to speak at this meeting (c.sayer@ucl.ac.uk).
