Day three of the #30DayMapChallenge - Polygons. This map shows the earths tectonic plates. I have overlayed all of the earthquakes with a magnitude greater than 4.0 over the last 20 years, coloured according to their magnitude (blue (smallest) - red (largest).

Island-hopping anurans: diversification dynamics in a widespread frog family
Abstract. Examining diversification patterns associated with dispersal, vicariance, and local adaptation is critical in elucidating drivers of speciation.

Awesome work by @deepakveerappan.bsky.social on this paper. Here we explore "Island-hopping anurans: diversification dynamics in a widespread frog family". The article is Open Access so go and check it out!
Hot off the press. Our study on the #biogeography of Ceratobatrachid #frogs is now out in @ZoolJLinnSoc.bsky.social
I had a chance to present this work at the World Congress of #herpetology last year. I tried to compile the highlights from this study. Read the open access paper for more details

An awesome evening for the launch of the new Adder Pilsner label from Allendale Brewery. Beer and adder talks (the work going on in the North Pennines). What is not to like?!
Lucy and Samuel did a fantastic job presenting the work we have been doing on Conservation Genomics of adders in the region.
