Prasiola crispa is a small terrestrial green alga. It has been recorded world-wide mostly from cold-temperate to polar regions.
Taxonomy
The species, first described as Ulva crispa Lightfoot, is the type of the genus Prasiola.[1] A lectotype was nominated for the species, the type location of which was provided in accompanying notation as walls that faced north and were favoured as urinals.[1]
The specific epithet is said to translate as "crisped", a reference to the irregular convolutions of the species.[1]
Description
This is a small green alga growing to about 6 cm long. The frond is round in shape, flattened. Generally one cell thick, the cells are arranged in rows or in groups of four.[2][3]
It seems to be an important food source for Antarctic collembolans.[4](p272)
The species has been used a model for the study of the effects of high intensities of UV radiation on photosynthesis.[4](p181)
Reproduction
Reproduction is by akinetes and aplanospores.[2]
Distribution
Recorded world-wide mostly from cold-temperate to polar regions,[1] e.g. from Iceland,[5] the British Isles including the Isle of Man, New Zealand, Japan and the Pacific shores of North America.[1][2] In Antarctica, the species lives near penguin colonies.[4](p593)
Conservation status
In Iceland, it is red listed as a vulnerable species (VU).[5]
