Selected morphological features were measured in five populations of the giant rosette plant Espeletia schultzii occurring along an elevation gradient from 2600 to 4200 m in the Venezuelan Andes. Pith ...

Heterogeneous environments can create differential selection pressures among populations, which may result in the evolution of local adaptations. Premating isolationmechanismsmay emerge due to limited ...

Long term trends of precipitation and wind speed were evaluated along elevation gradients to assess the dominant effects on snow water equivalence (SWE) using current and historical records of ...

The laboratory or industrial floor are not the only places where the interaction of light in the world is measured; sometimes research takes you into the great outdoors. If you are lucky enough to be ...
