Airborne laser scanning of natural forests in New Zealand reveals the influences of wind on forest carbon

Forests are a key component of the global carbon cycle, and research is needed into the effects of human-driven and natural processes on their carbon pools. Airborne laser scanning (ALS) produces detailed 3D maps of forest canopy structure from which aboveground carbon density can be estimated. Working with a ALS dataset collected over the 8049-km2 WellingtonContinue reading “Airborne laser scanning of natural forests in New Zealand reveals the influences of wind on forest carbon”

Enhancing of accuracy assessment for forest above-ground biomass estimates obtained from remote sensing via hypothesis testing and overfitting evaluation

The evaluation of accuracy is essential for assuring the reliability of ecological models. Usually, the accuracy of above-ground biomass (AGB) predictions obtained from remote sensing is assessed by the mean differences (MD), the root mean squared differences (RMSD), and the coefficient of determination (R2) between observed and predicted values. In this article we propose aContinue reading “Enhancing of accuracy assessment for forest above-ground biomass estimates obtained from remote sensing via hypothesis testing and overfitting evaluation”

Nitrous oxide emissions from sugarcane fields in the Brazilian Cerrado

We quantified N2O fluxes from a sugarcane experiment in the Brazilian Cerrado over an entire year, comparing the magnitude of response to different fertilizer treatments: mineral nitrogen (N), a liquid residue from bioethanol distillation known as vinasse (V) and a combination of both (NV), on irrigated and nonirrigated plots.

Forest soils in France are sequestering substantial amounts of carbon

The aim of this study was to assess whether French forest soils are sources or sinks of carbon and to quantify changes in soil organic carbon (SOC) stocks over time by resampling soil in long-term forest monitoring plots.

Advances in Microclimate Ecology Arising from Remote Sensing

This paper reviews the use of remote sensing in detecting microclimates in forests. We look into how we could combine remotely sensed data along with data from weather stations to map microclimates in forests in great detail, highlighting some opportunities they provide for ecology, conservation and climate change research.
