Great Reed Warbler

Great Reed Warbler (Acrocephalus arundinaceus) is classified as Critically Endangered (CR) on the IUCN Red List. Facing an extremely high risk of extinction in the wild due to severe population decline and habitat loss.

Hemiselmis anomala is a unicellular cryptomonad alga found in marine and estuarine environments, characterised by its asymmetric, kidney-shaped cell and two unequal flagella for swimming. It contains phycobilin pigments allowing photosynthesis and plays a role in marine and coastal primary production. Cryptomonads like this species are significant contributors to phytoplankton communities in diverse aquatic habitats.
