This is a piece of local algae I pulled from our towns hot spring

drain. It seems to be mostly layers of blue green that have collected

together to form mats. I have a lot more work to do and will need

another more powerful microscope to actually attempt to ID any further.

At Verkeerder Kill Falls, noticed this algal "curtain": a continuous sheet of water with long strings of algae hanging down. A curiosity.

A red algae that grows on snow, with the pouch for my point-and-shoot for scale.

I first saw this stuff above the Cathedral Lakes ca. 1989.

Wikipedia says it's also called 'watermelon snow', officially Chlamydomonas nivalis.

  

Tree roots and green algae

The fur of the Brown-throated Three-toed Sloth (Bradypus variegatus) is impregnated with algae. During the rainy season the fur of the sloth becomes green with growing algae. This sloth was photographed during the dry season when the algae is more brownish than green. It is believed that the algae/sloth is a symbiotic relationship. The hair on the sloth is grooved to provide the algae a place to live. Sloth hair is unique in that if the tip gets wet during a rain the water flows down the shaft (mixed with by-products from the algae) to the base of the hair where it is absorbed through the skin. The leaves that the sloth eats are low in energy producing nutrients (the reason sloths to not move fast). The absorbed by-products from the algae likely provide a needed food supplement.

Cladaphora are freshwater algae that grow on submerged rocks, logs and other hard surfaces. Research has linked cladaphora blooms to high phosphorus levels resulting from fertilizing lawns, poorly maintained septic systems, inadequate sewage treatment, agricultural runoff, and detergents containing phosphorus.

 

PondZilla is very effective, when used as an adjunct to an algaecide or herbacide*, at controlling filmantous bacteria in ponds such as cladophora.

 

Aquafix created PondZilla utilizing the latest in enzyme technology to degrade 30-60% of pond muck at 1/10th the cost of physical cleaning*. Pondzilla helps degrade muck and sludge in lakes and ponds by activating the muck layer and stimulating bacterial activity. It contains surface-activating agents, which liberate pond muck and allow the active ingredients to speed up nature’s natural decomposition cycle. It works particularly well in ponds with filamentous problems.

 

*While bacterial products cannot kill aquatic plant growth, when used with algaecides or herbicides, they can help restore natural balance.

There are some very cool colours in the algae near geysers in Yellowstone National Park.

This 200X magnification of the algae from our hot spring drain was

taken with the Intel QX5 microscope. I removed the bottom plate of

the microscope and added a light that is about fifty times brighter

to obtain this photo. More interesting photos to come.

see the winch line.. that's how they pull up the nets, some other are filling further down the cliff.. hard work in the scorching desert sun.. This algae is used in many products now. ( beauty prods I think ) --

took this one with my cellphone cam, i don't remember too well but i think this is an algae, most likely chlorophyceae with blue dye.

 

Si mal no recuerdo es un alga de las chlorophyceae, teñida con azul de metileno para ver cloroplastos. La tome con mi cel.
