Frost Tolerance Increases With Plant Height Among Co-Occurring Alpine Species in the Central Tibetan Plateau. [PDF]

Ecol Evol
Frost tolerance (LT50) varies greatly among species coexisting in an alpine community. Taller plants are more frost‐tolerant, reversing the expected intra‐community pattern. Evidence for a frost survival trade‐off: avoidance in short plants vs. tolerance in tall plants.

Description of the skull, braincase, and dentition of Moschognathus whaitsi (Dinocephalia, Tapinocephalia), and its palaeobiological and behavioral implications. [PDF]

Anat Rec (Hoboken)
Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

Succession of Lichens in Front of Retreating Glaciers in Sweden and Norway. [PDF]

Ecol Evol
We investigated the succession of lichens in glacier forefields in Sweden and Norway to assess how retreating ice shapes early lichen colonization and diversity patterns. Our results reveal consistent successional trends across sites and highlight the role of time since deglaciation and local environmental conditions in structuring lichen communities ...
