YouTube video by World Seagrass Association Ecophysiology Of Seagrass Seeds, with Kasper Elgetti Brodersen

The Ecophysiology of Seagrass Seeds talk is now available!

Kasper uses electrochemical & fiber-optic sensors, imaging and molecular techniques to study seagrass micro-landscapes and their impact on ecosystems under stress. Watch this and other talks in the #SeagrassSeminarSeries."

PFAS-herbicide diflufenican reduces the photosynthetic capacity in seagrass (Zostera marina L.) Global decline of seagrasses is directly linked with anthropogenic activities. One of the increasing threats, is marine pollution with a wide range of…

New paper: "PFAS-herbicide diflufenican reduces the photosynthetic capacity in seagrass"

Study addresses negative effects caused by #PFAS-herbicide diflufenican on #seagrass photobiology. We show reduced photosynthetic capacity of DFF exposed #plants.

Seed fever!
Researchers from the GPROLab are starting their experiments on Posidonia oceanica seeds and seedlings in Naples and Sicily.
Understanding the role of genetics, physiology and stress tolerance at early life stages is essential for their conservation and recovery

An underwater comeback is underway. Around the world, restoration projects are rewilding seagrass meadows—one of our greatest natural carbon stores. Here’s how ⬇️🌿🌱 #WorldRewildingDay

📢🌿 New Paper Alert!

In our latest study at @ccmar.bsky.social, we mapped #seagrass meadows across the #Algarve using a combination of systematic review, manual mapping, and machine learning techniques.

64,300 more seagrass seeds planted! 🌱

Thanks to local communities who have shown up year after year for these mighty, tiny seeds of hope! 💪

Let’s hear from the volunteers who helped harvest these very seeds and have planted them into the Forth. ⬇️ #RestorationForth

The most important part of the ocean you've never heard of The Saya de Malha Bank is one of the world’s largest seagrass fields and the planet’s most important carbon sinks. It faces incalculable risks that threaten the future of humanity.

Scaling Seagrass Mapping with Earth Genome and The Nature Conservancy

What do over a billion people live within 100km of? Seagrass! We are partnering with Earth Genome to put #seagrass back on the map. Our scalable blueprint for mapping seagrass will help build a future where #people and #nature thrive.

Så blev det Danmarks Country Overshoot Day 2025, og fra og med idag har vores lille grønne foregangsland brugt så mange naturressourcer, at alt vi forbruger fra nu af, er lig med et overtræk på naturkontoen. Godt, og heldigvis, at langt de fleste andre lande forbruger mindre end os.

Recovering essential seagrass meadows - People's Trust for Endangered Species Seagrass is a marine habitat that has declined drastically in the UK over the past century. Josh smith is recovering seagrass meadows

The UK has lost 90% of its #seagrass meadows🤯. Our intern Josh is working on the #Thames Estuary project to restore seagrass by evaluating the success of different techniques to recover the meadows👇

Saturday 1 March is World Seagrass Day! 🌊 🌿

Seagrass meadows store 19.9 gigatons of carbon and a single acre supports 50 million small invertebrates. 🦐

Today is #WorldSeagrassDay 🌿🌊

#Seagrass meadows are complex, highly productive and biologically rich habitats, home to many of #Australia’s #fish species🐟 📸 But they also need our protection 💚

Multi‐year monitoring shows higher species richness and diversity of fish assemblages in a Danish seagrass meadow as compared to neighbouring non‐vegetated areas Seagrass meadows provide an important nursery and feeding habitat for fish, globally. However, limited data exist on how these vegetated coastal ecosystems affect local fish stocks over longer time p...
