Balancing tracks and trees: Assessing railroad impact on Brazilian biodiversity
PLANTS, PEOPLE, PLANET, EarlyView.The Brazilian West–East Integration Railway (FIOL) aims to boost the national economy by improving commodity transport; however, it crosses three of Brazil's most biodiverse and fragile regions: the Caatinga, Cerrado and Atlantic Forest. Using digitised plant records and land‐use analyses, our study reveals significant vegetation loss within the ...

Georeferencing for Research Use (GRU): An integrated geospatial training paradigm for biocollections researchers and data providers [PDF]
Research Ideas and Outcomes, 2018 Georeferencing is the process of aligning a text description of a geographic location with a spatial location based on a geographic coordinate system. Training aids are commonly created around the georeferencing process to disseminate community standards

Mapping River Bed Topography in Whitewater Rapids Using Bathymetric LiDAR
River Research and Applications, EarlyView.ABSTRACT Bathymetric LiDAR captures river topography efficiently for clear and shallow water, but for mountain rivers, whitewater rapids still pose challenges. This study proposes a novel method to enable the extraction of bottom returns specifically in turbulent whitewater sections.

Remote Sensing in Ecology and Conservation, EarlyView.This study develops a novel application of UAV‐LiDAR and Red Green Blue (RGB) data and network analysis to enhance our understanding of boreal forest succession. The results indicate that tree height and spectral variables are the most influential predictors of plant functional type in random forest algorithms, and high overall accuracies were attained.
