More bog desmids from Widdybank Fell

Chris Carter continues to find some amazing-looking desmids in the gungy bits of Sphagnum I've been sending him from Widdybank Fell. Last time I sent him just 2 bits of Sphagnum and he has been busy for months finding more and more species of these microscopic algae in amongst the Sphagnum - and he's not finished yet!

Here are some of his latest finds -



There is a Dutch method of assessing the conservation value of wetland sites using desmid species called the Coesel method. Based on what Chris has found so far from just 5 small samples of Sphagnum from Widdybank Fell, the site now has a score of 8 or 9 out of 10. I'm sure its only a matter of time before it reaches 10 out of 10.

Yes, some of them do look a lot like pollen grains. Desmids are a type of microscopic alga that always have lateral symmetry. But I know very little about them. There is a link to a good Desmid site on my original post about bog micro-organisms from 19/1/2008 with lots more pictures.
