Arctic vegetation. About 1,702 species of plants live on the Arctic tundra, including flowering plants, short shrubs, herbs, grasses, and mosses. These plants are adapted to short, cold growing seasons. [ 1] They have the ability to withstand extremely cold temperatures in the winter (winter hardiness), and grow and reproduce in summer ...
These mountains are largely covered with permanent ice and snow, with permanent snow above about 2150 m, and are separated by valleys filled with ice fields and great glaciers. There are small patches that are not under ice and consist of rock, rubble and alpine tundra. Elevations of the ecoregion range from sea level (on the western coast) to ...
These complex interactions between plants, animals and abiotic factors in the tundra are held together by the permafrost layer, located 450 metres (1,480 ft) under the soil. [3] However climate change is causing this crucial layer of frozen soil to melt. As a result, tundra communities are becoming unstable and basic processes are breaking down.

Red-eye effect seen on a teenager. The red-eye effect in photography is the common appearance of red pupils in color photographs of the eyes of humans and several other animals. It occurs when using a photographic flash that is very close to the camera lens (as with most compact cameras) in ambient low light.
Normal fundus photographs of the left eye (left image) and right eye (right image), seen from front so that left in each image is to the person's right. Each fundus has no sign of disease or pathology. The gaze is into the camera, so in each picture the macula is in the center of the image, and the optic disk is located towards the nose. Both ...
