August 2014 Desktop Calendar

I met this moss, Scouleria aquatica, on the bryology field trip before this year's botany conference. In its current state it doesn't look very aquatic. It was growing on the rocks at the edge of the river in a zone that would be completely flooded in the springtime. During that time of the year it grows as a completely submerged aquatic moss. For the other part of the year it is high and dry for months at a time. When dry, they are in a state of suspended animation. Not photosynthesizing or growing at all

We added a bit of water to this patch and it made a dramatic change to the mosses appearance. The edges are gray, sandy, and dry, whereas the plants in the center are hydrated and green. It is amazing how rapidly mosses can take up water and start photosynthesizing.

2 - Right-click (or ctrl-click) on the image, and chose the option that says, "Set as Desktop Background" or "Use as Desktop Picture". The wording may vary.

3 - If the image does not fit your desktop neatly, you may have to adjust the image (Mac: System Preferences - Desktop and Screen Saver - Desktop; Windows: Control Panel - Display - Desktop) and choose "Fill screen" as the display mode of your background image.
