Nitrogen isotope tree-ring chronologies show that rising atmospheric CO2 has reduced nitrogen availability in boreal forests in Sweden, suggesting that elevated atmospheric CO2 is causing oligotrophication in boreal forests.

Abstract. Albinism is typically lethal in autotrophic plants due to the absence of photosynthetic pigments and functioning chloroplasts. Yet, rare exceptio

Warming temperatures can promote arctic tree seedling establishment and growth, but these effects depend on the environmental context and the seedlings' capacity to acquire limiting resources. Here, ....

Every species has a story—but without a name, that story may never be told. This Taxonomy Recognition Day, May 23rd, a coalition of Europe’s leading natural history museums and botanical gardens is calling on the world to celebrate the science that names, classifies, and protects life on Earth. From the Canary Islands to Norway, and Portugal to Greece, over 30 institutions are coming together to shine a spotlight on taxonomy—the foundation of biodiversity research and conservation. Events across Europe will include expert talks, debates, behind-the-scenes tours, hands-on activities, and networking opportunities, all aimed at raising awareness about the critical role of taxonomy in our world. Join the #NameItToSaveIt Movement This year, we’re asking everyone—scientists, students, nature lovers—to help make taxonomy visible. Here’s how you can participate: 📸 Take a photo of a plant, animal, fungus, or microbe that fascinates you. 🔤 Find its scientific name (or ask for help—we’re here for that!). 📲 Share it on social media with the hashtag #NameItToSaveIt. Every post is a voice for biodiversity. Let’s make this the loudest Taxonomy Recognition Day yet! Why It Matters A million species are currently threatened with extinction—many of them still unknown to science. Naming a species is the first step toward protecting it. Taxonomy plays a crucial role in agriculture, medicine, conservation, and policy-making. Without it, we cannot fully understand, protect, or restore the biodiversity that sustains us all.
