Mougeotia viridis algae undergoing sexual reproduction (conjugation) by producing zygospores. 40x Objective. From boggy area in acidic heath.
This was taken during Thanksgiving. For some reason , some purple algae started growing on the pond. It was beautiful!
Because of their calcified structure, coralline algae have a number of economic uses. The collection of unattached corallines (maërl) for use as soil conditioners dates to the 18th century. This is particularly significant in Britain and France, where more than 300,000 tonnes of Phymatolithon calcareum (Pallas) Adey & McKinnin and Lithothamnion corallioides are dredged annually. Some harvesting of maërl beds that span several thousand kilometres off the coast of Brazil takes place. These beds contain as-yet undetermined species belonging to the genera Lithothamnion and Lithophyllum. Maërl is also used as a food additive for cattle and pigs, as well as in the filtration of acidic drinking water.
The earliest use of corallines in medicine involved the preparation of a vermifuge from ground geniculate corallines of the genera Corallina and Jania. This use stopped towards the end of the 18th century. Medical science now uses corallines in the preparation of dental bone implants. The cell fusions provide the matrix for the regeneration of bone tissue.
Since coralline algae contain calcium carbonate, they fossilize fairly well. They are particularly significant as stratigraphic markers in petroleum geology. Coralline rock also functions as building stones, with the best examples being in Vienna, Austria.
We usually suffer from blue-green algae in the heat of summer, but it's autumn now and quite cool. Must be a lot of nutrients in the lagoon.

Gold Algae Eater
Gyrinocheilos aymonieri
This slender algae eater has a silver underbelly with a bright yellow/gold back. A horizontal line that is patterned runs along the side. The Gold Algae Eater comes from Northern India. It is usually kept in tanks for the purpose of keeping algae under control.
The main source of food is algae on plants, rocks, glass, and driftwood. Algae based wafers should be provided if there is a lack of algae.
Due to variable algal concentrations, vivid colors – from pale green to bright red – are created in the evaporation ponds. The color indicates the salinity of the ponds. Micro-organisms change their hues as the salinity of the pond increases. In low- to mid-salinity ponds, green algae are predominant. In middle- to high-salinity ponds, an alga called Dunaliella salina shifts the color to red. Millions of tiny brine shrimp create an orange cast in mid-salinity ponds. Other bacteria such as Stichococcus also contribute tints.

Not fun painting in the cold!
Great to see lots of top people today. A few absentees but a good meet up anyway.
Got to step up the shapes and get a new twist on the 3dish ting. More sketching required....
