Global patterns of treeline predictability and the gap between the forest and the treeline
Ecography, EarlyView.The alpine treeline is the highest elevation at which trees can grow, which is assumed to be controlled by temperature and globally predictable. However, many upper forest limits (UFLs) do not reach this elevation, due natural factors and human disturbance.

Detectability of Repeated Airborne Laser Scanning for Mountain Landslide Monitoring
Geosciences, 2018 Multi-temporal airborne laser scanning (ALS) surveys have become a prime consideration for detecting landslide movements and evaluating landslide risk in mountain areas. The minimum elevation change (or detectability) that can be detected by repeated ALS

Exploration, EarlyView.Science has not hit an absolute ceiling; it is stranded on a local peak. Viewed through Wright's fitness landscape, today's evaluation and funding systems over‐select, refining work within established paradigms while suppressing the drift and recombination needed to cross fitness valleys.
