Feldlerche

Celebrated across European literature and poetry for its complex, melodious song sung on the wing during spectacular display flights, Eurasian skylarks soar vertically hundreds of meters above open farmland, grassland, and heathland across Europe and Asia while producing an uninterrupted torrent of song lasting up to an hour. Males can produce over 700 distinct song phrases. Once enormously abundant across European farmland, skylark populations have declined over 70% since 1970 due to agricultural intensification.

Schizothrix calcicola is a filamentous cyanobacterium known for forming dense, calcareous crusts on rocks and soils in various terrestrial and aquatic habitats. It contains multiple trichomes within a common, multilayered sheath, contributing to biofilm and biocrust formation. Its conservation status is not evaluated.
