Mapping Scytonemin Pigment Content and Biocrust Functional Indicators Using High‐Resolution Multispectral Imagery

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
We demonstrate that high‐resolution multispectral imagery combined with machine learning can accurately predict key biocrust functional indicators, particularly the UV‐protective pigment scytonemin, across dryland ecosystems. Using fine‐scale imagery acquired in the Chihuahuan Desert and Colorado Plateau, we identified spectral bands strongly ...

The method of intelligent wireless sensor to improve the water permeability of permeable asphalt concrete pavement

open access: yesIET Networks, EarlyView., 2022
Abstract This research aims to study the intelligent wireless sensor to improve the water permeability of permeable asphalt concrete pavement. The water permeability of pavement is extremely important for the traffic environment. This study first briefly introduces the background and significance analysis, and then exemplifies the deployment algorithm ...

Using Airborne Laser Scanning and Sentinel‐2 to Understand Subcanopy Light Regimes and Understory Diversity of Vascular Plants in Temperate Mountain Forests

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
This study demonstrates that not just Airborne Laser Scanning, but also Sentinel‐2 can effectively estimate absolute canopy cover and canopy cover heterogeneity ‐ structural metrics that determine the subcanopy light regime, found to be linked to the vascular plant species richness in the understory of temperate mountain forests.

Citizen Science for Individual Identification of Pine Martens Martes martes From Camera Trap Footage

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Camera traps generate large volumes of wildlife footage, but identifying animals to the individual level remains challenging and time‐consuming. Using European pine martens in the Forest of Dean as a case study, we assessed whether citizen scientists could identify individuals from camera trap photos and videos.

How Passive Acoustic and Traditional Monitoring Estimate Bird Diversity Across Habitats

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
We compared traditional bird counts (PC) with passive acoustic monitoring (PAM) in a heterogeneous Alpine landscape. PAM recorded twice as many species, with a strong correlation between species richness and the bird counts (rs = 0.71); however, there were significant differences depending on habitat type.

The Application of Autonomous Fixed‐Wing Drones in the Sub‐Antarctic Operating Beyond Visual Line of Sight to Enable Large Area, Multi‐Species Population Monitoring in a Changing Environment

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Autonomous fixed‐wing drones operating beyond visual line of sight of the pilot were used to conduct the first aerial, multi‐species baseline reference survey at the sub‐Antarctic island of South Georgia. Long‐term population monitoring in this remote, challenging environment has historically proved difficult, with terrestrial monitoring generally ...
