A Functional Flows Framework for the Terminal Great Salt Lake Basin: Can We Have Our Lake and Drink It Too?

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Terminal basins provide unique aquatic environments that are often highly sensitive to streamflow contributions, making them a focal point for environmental water management. However, the water needs for terminal lake, wetland, and river ecosystems, and how they relate, remain a fundamental knowledge gap that constrains our ability to ...

Accounting for animal movement during aerial imaging surveys

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Animals are not stationary during aerial surveys; if their movements are related to the movement of the aerial platform, then bias can be introduced into subsequent population count estimates. We sought to establish a framework for assessing the impacts of animal movement on count error and platform bias by comparing aggregated counts and relative ...

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 ...

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.

Elucidating the Visual Snow Spectrum: A Latent Class Analysis Study

open access: yesBehavioural Neurology
Objective. People with visual snow syndrome (VSS) experience a range of perceptual phenomena, in addition to visual snow (VS; flickering pinpricks of light throughout the visual field). We investigated the patterns of perceptual phenomena associated with

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.
