Knee height is often right: evaluating device height effects on camera trapping rate
Remote Sensing in Ecology and Conservation, EarlyView.Camera trap deployment height can introduce systematic biases in detection trapping rates across species of different body sizes. Combining 172 paired sampling points in five experiments across Europe, North America and Africa, our results show that low cameras significantly increase detections of small‐ and medium‐sized species, whereas high cameras ...

Retrospective image analysis for long‐term demography using Google Earth imagery
Remote Sensing in Ecology and Conservation, EarlyView.We demonstrate that high‐resolution Google Earth imagery, combined with minimal field validation, enables retrospective tracking of individual invasive plants. The image shows one of the monitored individuals of Opuntia sp. in Greece. Our approach reveals long‐term demographic patterns, recruitment dynamics, and spatial expansion without continuous ...
