Isolation by environment
... Isolation by environment is defined as a pattern in which genetic differentiation increases with environmental differences, independent of geographic distance (Fig. 1; Wang & Summers 2010; Bradburd et al. 2013; Sexton et al. 2014). The important environmental variables may be continuous, such as ele ...

Organisms at high altitude
.jpg?width=300)
Organisms can live at high altitude, either on land, or while flying. Decreased oxygen availability and decreased temperature make life at high altitude challenging. Despite these environmental conditions, many species have been successfully adapted at high altitudes. Animals have developed physiological adaptations to enhance oxygen uptake and delivery to tissues which can be used to sustain metabolism. The strategies used by animals to adapt to high altitude depend on their morphology and phylogeny.
