The shape of a cornea can be measured and represented by color-coded maps in several ways. A number of different dioptric intervals has been used for color-coded maps and most topographers offer ...
Cold, steep, high-elevation slopes with less vegetation produce coarser and larger sediment than low-elevation, gentle slopes. This finding quantifies how sediment production varies with topography ...
A warming climate is likely to drive species to higher, cooler altitudes. A new study highlights a less obvious, yet crucial way in which their new habitat could differ from the one they leave behind.
