The samples of Usnea longissima were collected from Nyingchi Prefecture in Tibet Autonomous Region, Southwest China at five altitudes ranging from 2,989 to 4,048 m.
Since Darwin, researchers have explored how species adapt to different elevations. Tropical reptiles, typically diverse in warm lowlands, have also colonized high elevations on islands and the mainlan
Identifying drivers of dispersal limitation and genetic differentiation is a key goal in biogeography. We examine patterns of population connectivity and genetic diversity using Restriction-site Assoc
Recent studies are starting to show that genetic control over stochastic variation is a key evolutionary solution of single celled organisms in the face of unpredictable environments. This has been ex
