Leicester has long been one of the leading universities nationally for palaeontology & geology - this would be a terrible loss, as would the loss of other subjects such as modern languages:

Autumn in the garden. The pond vegetation is settling into tousled senescence, but behind it the giant Veronica vies with a self-seeded hazel for brightest autumn colour.

Highly recommended! Hanna’s team is doing ground-breaking research, Stockholm is a lovely city, and a Swedish PhD position is very attractive - an actual job with paid holidays, sick leave, parental leave and pension rights.
We have several open positions in my group, funded from the ERC Grant on the Early Sequestered Germline of Fungi. We search broadly for applicants at both PhD and master-level, with a dedicated interest in fungal evolutionary biology. Please forward and RT!

Amazing TV coverage today of the church in the mining town of Kiruna in Lapland being moved to allow expansion of the mine. It will move 1.5 km at a slow walking pace. So far, everything is going well.

Back in Uppsala, and at last this is turning into a descent butterfly summer! Lots of action in the garden today. Here's a small copper, Lycaena phlaeas, feeding on a coneflower.

I'm holidaying in Oban on the West Coast of Scotland, just as the country is battered by Storm Floris barreling in from the Atlantic. But the weather has its compensations: a storm petrel (Hydrobates pelagicus) is feeding just below our living-room window!

Yesterday I went out with my telephoto to try to capture some different aspects of life in and around the pond. Here's a frog, Rana temporaria, hiding under kingcup leaves at the edge of the water.

Not such a great photo because these are difficult to capture, but the other great joy of my pond at the moment is water plantain (Alisma plantago-aquatica), a European native. Rosettes of emergent leaves and upright flower stalks bearing clouds of small white flowers.

Two more flowers of James Brydon, because why not. And here’s a possible surprise for North American readers: would you believe, my latitude is equivalent to the northern tip of Labrador? Strange but true. 🌱🌱🌱

Now that everyone's back home from #EAVP22, I would just like to comment on the offensive claim by David Marjanović that I was "hiding" in Uppsala and had sent my junior lab members instead, supposedly because I was too afraid to face criticism of our recent paper in Nature on the earliest 1/3 🧪
