“It began with a few small strange patches of slime, clinging to the rocks of the Heber River in Canada. Within a year, the patches had become thick, blooming mats. Within a few years the mats had grown into a giant green snot.”
No, it’s not the trailer for an upcoming Hollywood movie (allthough it may very well become one).
It is the start of a very interesting BBC Earth program about the microscopic diatom alga, Didymosphenia geminata, commonly known as Didymo.
Although not yet reported found in the Baltic Sea, it might just be a matter of time…
A very interesting piece on how algae can be transported and gain world domination, or at least try.
A new scientific publication has just come out in the journal Estuarine, Coastal and Shelf Science by Ellen Schagerström, Helena Forslund, Lena Kautsky, Merli Pernoja and Jonne Kotta.
The article compared the thallus complexity and quantified the abundance and biomass of epiphytic algae and invertebrate taxa of the two fucoid species Fucus radicans and Fucus vesiculosus from sympatric sites in the Bothnian Sea on the Swedish coast and around the Estonian island Saaremaa.
Fucus radicans had a more complex thallus structure than Fucus vesiculosus within the whole study range, but both species were more complex in the Bothnian Sea compared to Estonia. The complexity of host algae did not contribute to their associated flora and fauna taxon richness; instead, the size of thalli was a good proxy for associated communities.
