EPCN Photo of the Month is from #Italy, submitted by Davide Taurozzi. A #temporary #pond at over 1,600 m in the Monti della Laga National Park, highlighting the remarkable diversity of European #mountain #freshwater habitats. 🏔️💧 Submissions are now open for next month’s Photo of the Month! 📸

Garden ponds are easy to dismiss as too small to matter, but they contribute meaningfully to #urbanbiodiversity. Our new paper looks at what zooplankton live in garden vs urban ponds, and how fish and urban cover shape those communities. Check it out: doi.org/10.1002/lno....

Zooplankton communities and their responses to fish presence and urban cover across garden and other urban ponds

As cities expand globally, the ratio of artificial to natural freshwater habitats is increasing. While public urban ponds have been the subject of an increasing number of biodiversity studies, the bi...

The hidden drivers of cyanobacterial blooms

Toxic blue-green algae blooms are a threat to lake ecosystems and can be toxic for humans and animals. At present, it is only possible to predict roughly when and where such blooms will form – based on water temperature and nutrient levels. Now, a long-term study by Eawag researchers shows that the accumulation of blue-green algae in a lake depends crucially on other plankton species: some organisms promote blue-green algae blooms, whilst others can prevent them even under favourable environmental conditions.

Can freshwater mussels help fight aquatic diseases? A new study found that the swan mussel (Anodonta cygnea) removes pathogenic Saprolegnia spores from the water, reducing their infectivity and lowering disease occurrence in fish eggs. Read more here: doi.org/10.1111/fwb....

Very glad to be at the #AIL2026 in Bilbao! I got the opportunity to present my current work with the University of León :)

#Ghostpond restoration is rocket fuelled conservation! Over 4-5 years we have seen 100s of wet-loving plants return to 30 resurrected ice age ponds in Norfolk, England. This year's surveys saw us find more scarce species: Marsh Pennywort, Marsh Speedwell & Fringed Heartwort. So Thrilled!!!

Fun to show @norfolknats.bsky.social some restored ancient #ghostponds today at East Harling with the fab @timholtwilson.bsky.social. At least 40 wetland plants in this pond resurrected 20 months ago. Most successful form of ecological restoration known? @billsutherland.bsky.social #ghostpond
