Estimating Rangeland Fine Fuel Biomass in Western Texas Using High-Resolution Aerial Imagery and Machine Learning

Remote Sensing, 2022
Rangeland fine fuel biomass is a key factor in determining fire spread and intensity, while the accuracy of biomass estimation is limited due to inherent heterogeneity in rangeland ecosystems.

UAV-based remote sensing for rangeland monitoring, a generalized and transparent workflow with an Australian lead

Ecological Informatics
Vegetation is a central indicator of rangeland condition, yet monitoring it across vast and heterogeneous dryland landscapes remains a major challenge. Although the advantages of remote sensing and unmanned aerial vehicles (UAVs) have been recognized for

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

Biological Reviews, EarlyView.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

Microclimate mediates the strength and direction of avian biotic interactions

Ecography, EarlyView.
Theory predicts that the strength and direction of species interactions can shift from being competitive in benign environments toward being facilitative in stressful environments. However, the environmental context dependency of species interactions has rarely been tested in animal communities.

Modeling the impacts of grazing management on livestock behavior and performance: A case study in the Peruvian Andes

Grassland Research, EarlyView.
Our modeling study shows that livestock management strongly influences grazing behavior and animal performance in the Peruvian Andes. Furthermore, adjusting stocking rates and improving animal distribution can enhance forage intake and body condition while increasing forage biomass.

Separation of trichothecene mycotoxins in a matrix of hemp (Cannabis sativa L.) seed, and quantification of deoxynivalenol in hemp grain infected with Fusarium graminearum

JSFA reports, EarlyView.
Abstract Background Fusarium graminearum, one of the causal agents of ear rot in maize and head blight of cereal grains, also infects hemp (Cannabis sativa L. containing a maximum of 0.3% tetrahydrocannabinol or THC). This fungal pathogen produces trichothecene mycotoxins when it infects maize and cereal grains, but little is known about its production

Extracting Fractional Vegetation Cover from Digital Photographs: A Comparison of In Situ, SamplePoint, and Image Classification Methods

Sensors, 2021
Fractional vegetation cover is a key indicator of rangeland health. However, survey techniques such as line-point intercept transect, pin frame quadrats, and visual cover estimates can be time-consuming and are prone to subjective variations.

Habitat characteristics along spring migration routes of elk, mule deer, and pronghorn in the southern San Juan Mountains

The Journal of Wildlife Management, EarlyView.
We evaluated habitat characteristics of spring migration routes and stopover sites for adult female elk (Cervus canadensis), mule deer (Odocoileus hemionus), and pronghorn (Antilocapra americana) in the San Juan Mountains (2021–2022) and found species‐specific differences in vegetation structure, terrain, and proximity to land cover types relative to ...
