Esmalte bem lindinho e muito fácil de pintar e limpar. Poderia ter usado 1 camda, mas o hábito fez eu usar 2. Pena que estraguei o dedo médio, na foto parece que tá horrível, mas na verdade foi bem pouquinho!
The algae somehow attaches itself to random rocks and thus stacks at the bottom of the ocean (more or less).
This brown alga does not constitutively release ROS. It hardly glows at all. Back to UAB in Antarctica website.
This is an image of two species of the filamentous algae Microspora (bottom two) and the diatom Fragilaria under a microscope using UV light and 1000x magnification. The red colour is the auto-fluorescence of the chlorophyll and the blue glow is from a fluorescent stain that binds to the cell walls of the algae.
Lake Menomin in Menomonie Wisconsin was overwhelmed with a blue-green algae bloom that caused the water to become toxic.
Found in pond water.

8x10 pinhole. Same position as last shot, but a couple feet above the ground so that perspective is more normal.

Happy Sliders Sunday!
For this shot, I zoomed in on the pond algae that was swirling around as a result of water that was flowing into the lake. I used a slow shutter speed to create some blur. For processing, I added a touch of HDR, applied Focal Zoom and finally added an Orton effect.

Purple loosestrife -- As an invasive species
Infestations result in dramatic disruption in water flow in rivers and canals, and a sharp decline in biological diversity as native food and cover plant species, notably cattails, are completely crowded out, and the life cycles of organisms from waterfowl to amphibians to algae are affected. A single plant may produce up to three million tiny seeds annually. Easily carried by wind and water, the seeds germinate in moist soils after overwintering. The plant can also sprout anew from pieces of root left in the soil or water. Once established, loosestrife stands are difficult and costly to remove by mechanical and chemical means.
