love that reporters now have to announce tech product launches the way your local water authority informs you of an effluent release about to hit your favourite beach

I cannot complain one iota about the vistas here. 📍 South Gobi, Mongolia
There’s a certain poetic neatness to the Pacific Swifts nesting on the State Ballet & Opera Theatre in the centre of Ulaanbaatar, Mongolia. I bloody love swifts, whether seen high on a mountain top or in the heart of a capital city. Don’t their screams in Summer bring everyone a bit of joy?
"This is the largest known Nomascus population and forms the core of a population of >8,000 groups." Important new study on wild crested gibbon population size/density - crucial for guiding conservation efforts. Congrats, @olliewearn.bsky.social et al.! link.springer.com/article/10.1...

Really interesting #dataviz that I’ve never seen before. Also what is happening to people once they enter their 40s?! (or alternatively what happened ~1985?)

Good to see this new report from bank J.P. Morgan on deep uncertainty about climate change & tipping points. One way it could significantly reduce this uncertainty is by stopping being the world's largest funder of oil & gas. jpmorgan.celero.site/s/ab29c67c/c... bank.green/banks/jpmorg...
1/8 🐺📢 Our study in Behavioral Ecology is out now! We explore the drivers of daily movements of wolves in human-dominated landscapes and found out that they shorten considerably their movements 🔗 Paper: sl1nk.com/xkue00q 🧵👇 (📸 Francisco J. Lema Fuentes).
There are more than 11,000 kinds of birds. I evaluated them all and made a definitive list of the 100 greatest names. I consider myself a bird name connoisseur but these blew me away. Over the next 10 days I'll add them to this thread. This is the hardest thing I’ve ever done.
Spotted a #wildcat, my 1st in broad daylight! 📍 Las Ubiñas-La Mesa Natural Park, Asturias, north of Spain Hybridisation likely an issue for the species in the park (as elsewhere); cat colonies are present in most villages. This one at least looks relatively pure bred to me (but genetics needed).
An ex-guillemot. On the beach in St Andrews (East Sands). Hoping these little guys are doing OK out there! #seabirds #deadseabird #beachcombing
I posted about this on my Facebook page, but I'm heartbroken about the God Squad's recent decision to allow oil and gas companies to harm Rice's Whales. You can learn more about these whales here: www.ourgulfwhale.org

I wrote about why every lab should have AI use guidelines, and how to do it. open.substack.com/pub/blekhman...
You need to make AI guidelines for your lab
Here's why you should, and how to start

Gold OA has allowed those in the Global South & in conservation NGOs w/out journal subscriptions to jump the paywall, finally. Whilst also, partially (could do a lot better) protecting the ability for those same people to publish through waivers. So there’s also that. #conservationscience 🧪🌍
Gold OA is a terrible model that has done a lot of harm. news.cancerresearchuk.org/2026/04/01/w...
NSF LTER program “archived”. LTER=“Long Term Ecological Research”. This program has been incredibly successful, incredibly frugal for what they accomplish, and…of course…targeted by evil know-nothings. My heart is breaking.
And as an extension of this: BirdNet and other global AI classifiers are not useful, generally, for biodiversity research. Despite the #AIhype 😏 For example, I saw a recent paper in PNAS using BirdNet concluding that bird diversity was higher in pasture and agriculture than in old-growth forest 🙃

Surprising piece of information: on average, European eel reach sexual maturity at large age than any whale species. And certainly much older than any other exploited fish species. That's why short-term measures are not useful. Eels need a moratorium mimicking the whaling ban (see below)
Celebrated #WorldRewildingDay looking for brown bear signs in a wild corner of northern Spain. Success! Evidence of a bear enjoying last autumn’s beech mast. We also found clues of other interactions with the beech tree: some glistening inkcaps, and a dormice’s cache of hazelnuts inside a treehole
I've had this from a journal: "Print your figure in a a letter size paper, place it *on the floor*, stand next to the page. Any text or number that you can´t read from that distance needs to be enlarged" Who is reading papers like this?! Also, I haven't had access to a printer since about 2007...
At the sharp edge of defending nature across the planet, rangers suffer. That’s for sure. They are also largely overlooked and undervalued. Hence, the importance of this call for urgent mental health support for rangers👇 Now that we can’t claim we didn’t know, what are we all going to do about it?
🚨New Paper🚨'Conservation Rangers Urgently Need Mental Health Provision' in @consletters.bsky.social by Soofi et al. inc @drdavidlroberts.bsky.social @dice-kent.bsky.social Great work by Soofi bringing this paper together!!! doi.org/10.1111/con4...
My kind of paper: tech (collars/tags), cool movement data, a hypothesis rooted in field observations, and a surprising finding!
For decades biologists assumed ravens follow wolves to their kills. Our paper @science.org shows something different: ravens rarely follow wolves far. Instead they remember areas where wolf kills are common and return to them—sometimes from >150 km away. doi.org/10.1126/science.adz9467 📷Dan Stahler
In 2023, I sought to explain to a parliamentary committee what a structural collapse of the global food system would look like, and why this this is plausible - even likely. I think the likelihood has just ratcheted up a notch. I beg you to read and understand. Thanks www.monbiot.com/2023/03/09/t...

A gulf in public understanding prevents us from seeing how and why our food supply is at risk.

Incredibly shortsighted decision by our govt to cut development funding, including taking an axe to nature recovery projects. It diminishes us a country, both at home & abroad. And so we slip inexorably ever closer to the little Britain dream of Farage and his billionaire mates.

You can now add (for $20) an AI agent to your RStudio session… Any support for non-profits @posit.co? This could help to speed up analyses in wildlife conservation.
Today we're releasing AI for RStudio. It's really, really good—I'd encourage you to point it at the messiest data sources you have and see what it can do. www.simonpcouch.com/blog/2026-03...
Although we have known this for many years—e.g. @neobirdconserve financed early work by Vitek Jirinek—this should have been the top news headline last week. These declines in 'pristine' tropical forests are well-documented, poorly understood and continue apace. www.science.org/content/arti...
Birds are vanishing from tropical forests. Is another ‘silent spring’ coming?

Some argue protected areas in fire-prone landscapes can undermine forest carbon (fuel build-up → higher fire risk). This paper shows Spanish protected areas consistently outperform comparable unprotected lands, strongest in National Parks. iopscience.iop.org/article/10.1...
