Tree species classification and estimation of stem volume and DBH based on single tree extraction by exploiting airborne full-waveform LiDAR data
Moving in the Anthropocene: Global reductions in terrestrial mammalian movements
Using a unique GPS-tracking database of 803 individuals across 57 species, it is found that movements of mammals in areas with a comparatively high human footprint were on average one-half to one-third the extent of their movements in area with a low human footprint.
Partial migration in roe deer: migratory and resident tactics are end points of a behavioural gradient determined by ecological factors
The results support the idea that migration encompasses a behavioural continuum, with one-trip migration and residence as its end points, while commuting and multi- trip migration with short residence times in seasonal ranges are intermediate tactics.

Factors affecting the spatio-temporal dispersion of Ips typographus (L.) in Bavarian Forest National Park: A long-term quantitative landscape-level analysis
Vegetation Indices for Mapping Canopy Foliar Nitrogen in a Mixed Temperate Forest
The findings demonstrated the feasibility of using hyperspectral vegetation indices to estimate %N in a mixed temperate forest which may relate to the effect of the physical basis of nitrogen absorption features on canopy reflectance, or the biological links between nitrogen, chlorophyll, and canopy structure.
New Possibilities of Observing Animal Behaviour from a Distance Using Activity Sensors in Gps-Collars: An Attempt to Calibrate Remotely Collected Activity Data with Direct Behavioural Observations in…
The potential of dual-axis acceleration sensors in GPS-collars for estimating the activity of wild-living red deer is demonstrated and further observations of activity on more individuals should be performed to take into account inter-individual variability and to improve the predictive power of the threshold values.
Forecasting potential bark beetle outbreaks based on spruce forest vitality using hyperspectral remote-sensing techniques at different scales
