Automated extraction of right whale morphometric data from drone aerial photographs

Remote Sensing in Ecology and Conservation, EarlyView.
Aerial photogrammetry is a popular non‐invasive method for measuring marine mammal body size, body morphometrics, and body condition, but processing large datasets efficiently remains challenging. We developed a machine learning algorithm using Mask R‐CNN models to automatically measure body morphometrics of southern right whales from aerial ...

Advancing the mapping of vegetation structure in savannas using Sentinel‐1 imagery

Remote Sensing in Ecology and Conservation, EarlyView.
As vegetation structure monitoring is important for the understanding and conservation of savanna ecosystems, we explored the utility of C‐band synthetic aperture radar imagery for mapping both grassland and woody vegetation structure in the Greater Serengeti‐Mara Ecosystem.

Hyperspectral imagery, LiDAR point clouds, and environmental DNA to assess land‐water linkage of biodiversity across aquatic functional feeding groups

Remote Sensing in Ecology and Conservation, EarlyView.
Functional feeding groups (FFGs) are key components sustaining ecosystem functioning in riverine ecosystems. In this study, we conducted an airborne imaging spectroscopy campaign and a systematic environmental DNA (eDNA) river water sampling in a 740‐km2 mountainous catchment, combined with light detection and ranging (LiDAR) point clouds, to obtain ...

Night lights from space: potential of SDGSAT‐1 for ecological applications

Remote Sensing in Ecology and Conservation, EarlyView.
Our study emphasizes the importance of advancing ALAN monitoring from space for ecology and conservation, and it highlights the novel opportunities of SDGSAT‐1. We discuss shortcomings that need to be resolved and identify promising avenues for sound ecological impact assessments of ALAN on ecosystems using space‐borne remote sensing.

Spatiotemporal patterns and driving factors for vegetation growth status in the upper reaches of the Yellow River

River, EarlyView.
This study developed the WEP‐CHC model, integrating vegetation growth dynamics into the hydrological WEP framework, to explore the spatiotemporal patterns and driving mechanisms of vegetation growth status (VGS) in the upper Yellow River. The results revealed significant spatiotemporal variability in VGS, with annual hydrothermal conditions and soil ...
