Reporting the death of Prof Alan M. Wilson FRS in a light plane crash in Namibia, while doing wildlife research. He was 62. He built and flew his own planes but I do not know if he either built or flew this one. He even flew from London to Cromer to meet me for lunch (he brought cake). Devastated.

1977. A small colony of Wall Lizard (Podarcis muralis) are introduced to a pocket of brownfield in Eltham, SE3. 2026, 49yrs later, the population is still present, and self-sustaining.

Today, I was given access to the site, and thankfully the lizards got the memo!

I believe it was the plane they built, but it was being flown by a professional pilot at the time, with Alan as the passenger.

A North Atlantic Right Whale swims in calm blue water, a gathering of smaller animals, possibly fish, around its mouth.

Only about 70 reproductively active female North Atlantic right whales remain.

But the Trump administration just announced plans to revoke vessel speed restrictions on the Atlantic coast that protect these critically endangered whales from deadly ship strikes.

Fascinating watching this Jay from my office window. Buries acorn - looks around for something to cover it with, and then looks for another object to go on top (perhaps to help relocate?), regurgitates next one ready, and flies off.

Moth perched on a streetlamp. Our work suggests that light suppresses activity in moths, so once attracted to a light they are prevented from escape.

Eye-opening findings on how light suppresses moth activity. Light attracts moths, but what if we've been missing a much more pervasive effect where even sky-glow light levels make them freeze?
