#2939 - 2016 Day 17: Basically, if you're going to slither all over something, be careful not to leave footprints. Something has left this trail in the algae on one of our kayaks.
Note to self: clean kayaks and use them!!
The substance on these branches is 'Trentepohlia', a genus of filamentous green chlorophyte algae which lives on tree trunks and wet logs. The strong brownish-orange color of the filaments, which mask the green of the chlorophyll, is caused by the presence of large quantities of carotenoid pigments. I noticed this unusual algae growing on some Monterey Cypress trees at the top of a high bluff overlooking Woodcrest Beach on the Pacific Coast in Half Moon Bay California.
I watched this American Goldfinch (Spinus tristis) pluck algae from a small pond and then eat it. At first I thought it was eating the Duckweed but after watching closely with binoculars I saw that it was after the green algae. Checking the literature I found out that this has been observed a number of times but usually when the water level had dropped leaving the algae high and dry for the birds. This Goldfinch was not waiting and was plucking the algae from under the surface of the water. Small pond at Centennial Park, Howard County, Maryland.
They're not very good pictures, but I loved the patterns that this created with lots of layers of algae in perfectly clear water
In he late spring, the stream has dried up and all that is left are algae filled pools. At first when we started the hike, it looked completely dry. That would have been disappointing because the description in Afoot and Afield indicated that there would be a pool with a waterfall along the hike.

Pebbles of various sizes line the bottom of thie shallow and beautiful section of the Bow River, with gently rippled water and golden morning sunlight creating a lovely abstract effect as they flowed over the rocks.
I thought this shot was particularly cool as a patch of algae had built up around one of the larger pebbles, providing wonderful contrast of both color and texture to the surrounding rocks and water!
This is the trail of a bullet through an enameled steel appliance lid, attached to a fencepost on a farm near Defeated Creek in Tennessee. The green smudge is algae growing on the enamel, and the curvy trails in the algae are the tracks of snails as they inch forward, their mouths moving in an arc from one side to the other, their radulae scraping off the algae. Very efficient. Whoever hung this metal panel on this fencepost created a snail feeder.
I am growing algae. What I can't figure out is the perfectly straight line of demarkation between "algae" and "no algae" on the back of the tank. The algae just stops, six inches from the top. Not a gradual cessation, either. A perfectly straight and sudden boundary. I can't think of any explanation. If you have one, I'd love to hear it!
low water flow means plenty of food for sandpipers and willets....there were a bunch of the former and a few of the latter
Algae, possibly gloeocapsa, at 600x. Found in a sample from an artificial pond in the park near 1st Street and Chesterfield in North Vancouver, BC, Canada.
Toward Dunwich, there were several small pools that had formed a short distance from the beach.
There is lots of algae in these pools & the presence of it, makes for some very vivid colours.
Ryan Davis and Sandia National Laboratories colleagues have developed a method to recycle critical and costly algae cultivation nutrients phosphate and nitrogen.

Algae Bloom off the Coast of Estonia on July 16th, 2002. Cyanobacteria can be found in almost every terrestrial and aquatic habitat. With the appropriate conditions these can bloom and be seen from space as blue-green patches that swirl following surface currents. Lines cutting across the image are the traces of ships. Factors that lead to these blooms include low winds, increasing temperatures, and nutrients such as phosphorus (often byproducts of fertilizer runoff along the rivers). These blooms can be toxic and are often monitored from air and space.
