Plant taxonomy is disappearing - and so is our ability to protect species 🍂

Nearly half of countries have fewer than 10 plant taxonomists. Kew is working to close the gap, but we need more experts fast.

Pollinator contribution to crop production: a temporal and economic assessment in Portugal - Regional Environmental Change Pollination is a key ecosystem service that supports agriculture and food security, with significant economic relevance. Yet, national-scale assessments remain scarce, despite their critical role in i...

🐝 Pollinators are worth billions. A new study from the FLOWer Lab shows they secure over €2B/year for PT agriculture, with €1.1B coming from wild pollinators. Protecting them is essential for our food, economy and future.

Our paper shows that most ectomycorrhizal fungal species (83% of OTUs) are "dark taxa": species we detect in DNA, but can't match to known species names. We map global "darkspots" - the parts of the world most in need of more research. @spun.earth @ethz.ch www.cell.com/current-biol...

Diagram showing how degraded plastics release microplastics that affect honey bee health. Plastics like polyethene and polystyrene break down, leading to bee exposure. Effects on bees include impaired immunity, gene expression changes, reduced gut microbiota, cognitive issues, respiratory failure, and higher mortality.

Cladonia, a lichen, grows in a white puff only a few inches above a carpet of a moss called Pleurozium. Like the iconic black spruce (Picea) of the boreal belt, they harbor diverse endophytic fungi that live symbiotically within their healthy tissues.

End of ‘beaver bombing’ as wild beavers legally return to England Four beavers released and this will be the first official, legal release of these creatures into the wild in England, in four centuries  - as opposed to the releases into fenced areas.

Wild beavers have legally returned to English waterways for the first time in four centuries.

Alex Thomson explains why the release of these remarkable engineers into the wetlands of Purbeck in Dorset is so important.
