"Even on the same field worms are much more frequent in some places than in others, without any visible difference in the nature of the soil"
We have a project with Ron Corstanje at Cranfield and Paul Eggleton at the Natural History Museum to try and solve the puzzle of why earthworms are where they are.
Last week Jo, myself and Jess finally finished processing our 500 odd soil samples (analysed for pH, soil organic matter, nutrients, bacterial activity etc) and David at the Natural History Museum finished identifying all the earthworms. We are now the proud owners of an incredible data set. For seven farms dotted around the UK we have full soil property information and know what earthworms are present. We have passed the information on to Ron Corstanje at Cranfield our geostatistician to tell us what it all means. Hopefully in five or six months time we'll be able to predict what controls the occurrence and diversity of earthworms in grassland sites in the UK.
However, there's no time to be idle. The summer term at university is always rather odd. With little teaching it always feels like there should be lots of spare time however there is lots of marking to be done. I've also been up to Glasgow to act as external examiner for their environmental chemistry degree and, yesterday was in Leiden, The Netherlands to help examine Hao Qiu's PhD thesis that he completed with Martina Vijver and Willie Peijnenburg. It was a long day ( up at 5 for a flight from Leeds Bradford to Schipol and back into Leeds Bradford at about 9.20 in the evening) but a good thesis and an excellent meal afterwards. The European system is interestingly different to that in the UK. In the UK the PhD student is grilled for 1 to 4 hours (or even all day in extreme cases) by a single examiner. It is a real academically challenging rite of passage which I'm sure is valuable though draining. In the Netherlands we had a panel of 7 examiners with 5 to 8 minutes each to question the candidate in front of an audience so it's a completely different experience. Both systems have their merits. I'm not sure about the robes we had to wear during the viva though...

|Getting ready for the World cup in the Netherlands|
World Cup fever is beginning to take root in the Environment department as well. We did the World Cup sweep stake today and I was delighted to draw Brasil (though as I was organising the draw this raised some questions from my colleagues) - roll on the finals.
