Harnessing the power of machine and deep learning for transferring joint species distribution models considering the structure of biotic interactions

Ecography, EarlyView.
The transferability of single or joint species distribution models ((j)SDMs) depends on their ability to predict beyond the observed environmental range and to remain consistent despite shifts in biotic interactions. Transfer accuracy may be improved by recent advances in the application of deep learning that provide greater flexibility and potentially

Estimation of Forest Height and Canopy Density From a Single InSAR Correlation Coefficient [PDF]

IEEE Geoscience and Remote Sensing Letters, 2015
A two-level model (TLM) is introduced and investigated for the estimation of forest height and canopy density from a single ground-corrected InSAR complex correlation coefficient. The TLM models forest as two scattering levels, namely, ground and vegetation, separated by a distance Delta h and with area-weighted backscatter ratio mu.

Biodiversity and biomass co‐regulate urban forest drought resistance

Frontiers in Ecology and the Environment, EarlyView.
Severe droughts induced by climate change present substantial challenges to urban forests. While the role that species richness plays in enhancing drought resistance in natural ecosystems has been highlighted in previous studies, its impact within urban forests remains less understood.

The effect of canopy position on growth and mortality in mixed sapling communities during self-thinning [PDF]

, 2009
This research investigates how species in the sapling phase differ in growth and survival depending on light availability (as estimated by canopy position) by means of tree-ring analysis and modelling mortality.

The design of a Space-borne multispectral canopy LiDAR to estimate global carbon stock and gross primary productivity [PDF]

, 2011
Understanding the dynamics of the global carbon cycle is one of the most challenging issues for the scientific community. The ability to measure the magnitude of terrestrial carbon sinks as well as monitoring the short and long term changes is vital for ...

Estimation of Forest Canopy Height in Hilly Areas Using Lidar Waveform Data

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2019
Forest canopy height (FCH) is a key parameter in the estimation of forest biomass and productivity. However, areas with hilly or mountainous terrain present a genuine challenge to extract the vertical structural parameters by using the large footprint Lidar full waveform data.
