Image 1: Batrachospermum. A greenish coloured species. Note a few diatoms living in the mucilage.
Image 2: Ceratium dominated plankton. Ceratium belongs the major group of Dinophytes, the Dinoflagellates.
Image 3: Ceratium among filamentous Cyanophytes.
Image 4: Dinobryon. Very common in the plankton of lakes or pools which are relatively poor in nutrients and not very alkaline.
For Microscope Monday 🔬 we're sharing some mesmerising mini marvels from #FreshwaterAlgae: Their #microscopic world explored by Hilda Canter-Lund & John WG Lund.
The book hopes to "take people into a world of great beauty & fascination which they normally never see..."

Once common in our glacial lakes, the Arctic charr is now increasingly under pressure. We're supporting @freshwaterbio.bsky.social to improve this fish's spawning habitats, especially in the Lake District.

Much talk all the time of freshwater wetlands being great filters & cleaning water. We must remember that sending dirty water into wetlands destroys them. There is nothing more certain in science than that. Make wetlands clean!!! @ramsar.org @freshwaterbio.bsky.social

This Microscope Monday 🔬 for your #FreshwaterPearlMussel pleasure... we present some recently excysted juveniles.
The juveniles, from the #RiverIrt, #WestCumbria, will now be reared at the Ark (for 3 years min.) before being translocated back to their native river to reinforce the wild population.

Hello #FreshwaterPearlMussel friends! This Microscope Monday 🔬 we have some fascinating photos of glochidia encystment on a brown trout.
An observation from the FBA Ark is that the growth of encysted glochidia is highly correlated to water temperature.

Oliver H. Wilson (right) restocking a small river in Norfolk, c.1950.
The lorry from the Weston Fishery (Weston Longville, Norfolk) equipped with fish tank and oxygen cylinder making a delivery of coarse fish to a Norfolk river, c.1950. Oliver H. Wilson is on the right.
A view of the River Wensum in winter at Swanton Morley.The river flows through a broad floodplain backed by some woods and a farmhouse in the distance.
What's to be done about the River Wensum? It is sadly degraded from the biodiverse Chalk River habitat which my Gt Uncle Oliver (the Weston Fishery) knew 80 years ago. Even though it is a SSSI and a SAC. Strong words
