World Wetlands Day 2026 A call for greater protection and stewardship of the world’s peatlands

πŸ“’Feb 2 is #WorldWetlandsDay! A day to celebrate the world's wetlands, including bogs, fens, and swamps.

Many Ramsar sites are #peatlands but there are large gaps in global cover. For more on this issue, and on peatlands and @ramsar.org, see my new Peatpedia post: open.substack.com/pub/peatpedi...

Integrating Characteristic Arctic Vegetation in a Land Surface Model Improves Representation of Carbon Dynamics Across a Tundra Landscape Refined Arctic plant functional types in simulations improved landscape-level fluxes, but carbon allocation parameters need further review Incorporating representative tundra vegetation increased...

πŸ“’ New paper!
Improving how models represent Arctic veg ⬆️ ability to simulate C dynamics. Using obs from towers/chambers/drones/aircraft, we found better rep of heterogeneity=better predictions, bringing models closer to obs and highlighting key gaps for scaling (shrubs!)

So kommunizieren Fichten vor einer Sonnenfinsternis Fichten reagieren nicht nur auf Sonnenfinsternisse – sie synchronisieren ihre Signale Stunden zuvor und warnen so den gesamten Wald.

Die Natur ist einfach unglaublich.

Jeden Tag entdecken Forschende mehr von ihren Geheimnissen.

So vieles haben wir schon zerstΓΆrt, was auf immer verloren gegangen ist.

Aussterben ist das EndgΓΌltigste, das man auf diesem Planeten tun kann.
