New paper lead by @etspencer.bsky.social We use biologging to understand why great hammerheads may specialize on large prey like other sharks. If they hunt blacktips off south Florida then they probably only have to catch a shark once per month link.springer.com/journal/442

Happy International Angel Shark Day, especially to all my wonderful colleagues @angelsharkproject.bsky.social

These are a special, and heavily threatened set of species.

Happy International Angel Shark Day from the IUCN SSC Shark Specialist Group!

There are at least 24 species of angel sharks (Order Squatiniformes) and they occur across the world, from temperate to tropical waters, and from depths of <1m to 1,300m.

Breaking news: it appears Emperor penguin populations in Antarctica are declining faster than predicted.

Latest satellite data shows a massive 22% drop in penguin numbers over the last 15 years in key regions.

This is more than double the rate of loss that experts had expected...

Still hope for coral reefs. Using 28-years of data in Seychelles, we find reefs recovering 4-5 years faster from the 2016 bleaching event, than they did after 1998. Also, a reef that had regime-shifted to macroalgae for over 15 years, is recovering to coral.

Assessing coral reefs across the inner Seychelles islands, using a 28-year dataset, we document faster coral recovery from the 2016 than the 1998 marine heatwave events. Further, a reef that had regi....

Great to see new information about smalltooth sawfish in Cuba out today. Evidence that a local population may still exist, but numbers are likely low and action is required (and suggested in the paper).

Really nice looking postion open here at SLU Sweden: Professor (fully tenured) in conservation ecology with focus on biodiversity linked to forest management & green infrastructure.

It is also at our Alnarp campus which is...well...rather nice & even has a castle! 🧪🌎

www.slu.se/en/about-slu...
A green lawn stretches towards an old castl, three wings of the castle can be seen with multiple arched entries and at leasted 4 levels of whindows. Two large sections of the castle walls are covered with green vine with leaves or red vine with red or orange leaves. This is the opposite side of the castle in the previous picture. Here three distinct 'towers' cant be see with two sections of building between them. This side of the case appears to only have one entrance and the sections between the towers are covered in thick green foilage with the exception of the 12 windows in each section spread over three floors.
