Waterflea with an inprint of an Asterionella diatom. Waterflea bares unborne waterfleas in its back

Asterionella is a radial shaped diatom like spokes of a cart wheel.

Very young waterflea with yolk.

We're besotted by #Bosmina! So this Microscope Monday 🔬 we're enjoying getting up close with #Cladocera, aka the #WaterFlea!

Geoffrey Fryer’s impressive half century — Freshwater Biological Association FBA Fellows Martyn Kelly and Catherine Duigan remind us of a significant anniversary in the FBA’s history. Fifty years ago this year, Geoffrey Fryer, then a scientist at the FBA’s Windermere laborato...

Careers can be enriched by chance encounters and friendships - research today reminded me of the kindness and wisdom of Geoffrey Fryer, #freshwater #ecologist.

These included an amphipod used in water toxicity assessments, and a ctenopod (waterflea), which can indicate the pH level of the water. Bea’s work provides a crucial baseline for monitoring the health of the reservoir and will help ensure the community has access to safe water. 4/5 #cladocera

New FWB paper shows ducks often disperse aquatic crustacean eggs >100 km, but species with larger eggs are moved over greater distances #cladocera @WileyEcolEvol @ebdonana @freshwaterbio @BenthosNews @AIL_limnologia @sibecol @BES_AquaEco @Rheophillic

Lough Feeagh #zooplankton from July 2016 is FULL of PREDATORS...big fat Bythotrephes longimanus and also lots of Leptodora kindtii, feeding on all the Diaphanosoma brachyurum that bloom in summer. #BurrishooleLTER @MarineInst #cladocera #minibeasts

NOVEMBER: back to the microscope for winter #zooplankton enumeration. #BurrishooleLTER backlog of monthly samples. Quite a treat to do a sample every morning while listening to the radio 🙂#minibeasts #freshwater #cladocera #copepoda #Lakes

1st African study of #dispersal of invertebrates by waterbirds. #cladocera and #bryozoa abundant, as seen elsewhere
