[Nicholas Dulvy @NickDulvy]

New #GlobalSharkTrends study published in @ScienceMagazine reveals that #overfishing has more than halved shark & ray populations over the past 50-years causing widespread erosion of ecological function and exceptionally high extinction risk

Dr. @sjanefoster says bottom trawling, which drags heavy nets across the ocean floor, is one of the most destructive #fishing practices that must be overhauled to conserve species both for commercial use & to preserve #ocean ecosystem. @projectseahorse https://t.co/rqyH0v2MIF

“This is the clearest picture we’ve had of the breadth of bottom trawling. It reveals just how many species are being caught, and how much we have been missing,” said @sjanefoster @projectseahorse . https://t.co/dBDeNKHllA

Tigers are making a comeback and communities are leading the way🐅

Through @IUCN’s Integrated Tiger Habitat Conservation Programme:
• 10,500+ ha of habitat restored
• 500,000+ trees planted
• 10,000+ people trained
• 95,000+ people benefiting from sustainable livelihoods

Protecting tigers means restoring entire landscapes, for nature and people.

Lake Tanganyika’s fish stocks haven’t been fully assessed in nearly 30 years, despite supporting millions.

A new #FISH4ACP 2,500 km survey is gathering data to support sustainable management.

La organización internacional Oceana documentó que el 38 % de los pescados comercializados en México son sustituidos por especies distintas a las ofrecidas al consumidor. De acuerdo con el reporte “Gato x Liebre: engaño evidente”, esta cifra representa casi el doble del promedio internacional del 20 % reportado por la Organización de las Naciones Unidas para la Alimentación y la Agricultura.

Dennis Ritchie created C in the early 1970s without Google, Stack Overflow, GitHub, or any AI ( Claude, Cursor, Codex) assistant.

- No VC funding.
- No viral launch.
- No TED talk.
- Just two engineers at Bell Labs. A terminal. And a problem to solve.

He built a language that fit in kilobytes.

50 years later, it runs everything.

Linux kernel. Windows. macOS.

Every iPhone. Every Android.

NASA’s deep space probes.

The International Space Station.

> Python borrowed from it.
> Java borrowed from it.
> JavaScript borrowed from it.

If you have ever written a single line of code in any language, you did it in Dennis Ritchie’s shadow.

He died in 2011.
The same week as Steve Jobs.
Jobs got the front pages.
Ritchie got silence.

This Legend deserves to be celebrated.

Still the best course on modeling IMO — a gift to the scientific community that it’s all freely available.

And now I feel old because I took this course the first year of my PhD in 2014, over a decade ago 🥲

We’re missing a global indicator to track insects. By analyzing thousands of butterfly populations, we highlight both promising signals and key challenges—showing why these taxa are strong candidates for building a Global Index to support conservation. https://t.co/fbXCIiOUff
