Spatial variation in liana effects on host‐tree allometry and biomass in an intact tropical forest

Ecography, EarlyView.
Lianas are increasing in abundance across the tropics, yet local spatial variation in their effects on host‐tree allometry and biomass, and the drivers of this variation within forests, remain poorly understood. Using field inventory, drone photogrammetry, and terrestrial laser scanning (TLS) across a 50‐ha plot on Barro Colorado Island, Panama, we ...

Post-Fire Changes in Forest Biomass Retrieved by Airborne LiDAR in Amazonia

Remote Sensing, 2016
Fire is one of the main factors directly impacting Amazonian forest biomass and dynamics. Because of Amazonia’s large geographical extent, remote sensing techniques are required for comprehensively assessing forest fire impacts at the landscape level. In

Review of the Salpausselkä ice‐marginal formations in Finland

Journal of Quaternary Science, EarlyView.
ABSTRACT Extensive Salpausselkä ice‐marginal formations were deposited in southern and eastern Finland during the Weichselian deglaciation. These comprise three major ridges (I, II, and III Salpausselkäs) and their eastern counterparts (Tuupovaara, Koitere, and Pielisjärvi), together forming laterally continuous ice‐marginal formations extending ...
