In her four-chapter series called “The Pigment Change,” rather than developing photos on photographic paper, she prints them directly onto plants. “I just put a negative on top of the leaf ...
The southern edge of the Canadian Arctic tundra is met by an arboreal tree line - the Arctic forest tundra transition zone. In order to adapt to the extreme conditions of the Arctic, plants have: reduced leaf size to minimize water loss to wind; fuzzy hair-like structures or alternatively grow in mats to protect themselves from snow and wind damage
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.
We've all grown up thinking that sitting too close to the television is damaging to our eyes ... but that might not be the case. Technology spawns lots of confusion ... and a few affectionately ...
Alpine tundra. Hikers traversing the Franconia Ridge in the White Mountains of New Hampshire, much of which is in the alpine zone. Alpine tundra is a type of natural region or biome that does not contain trees because it is at high elevation, with an associated harsh climate. As the latitude of a location approaches the poles, the threshold ...
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 ...
