A comparison of monitoring methods for inferring demographics of a pond‐breeding amphibian population over 14 years

The Journal of Wildlife Management, EarlyView.
We used 4 sampling methods to estimate or index the abundance and sex ratio of spotted salamanders (Ambystoma maculatum) over 14 years. The present study highlights the importance of considering individual heterogeneity in capture probability when estimating abundance of pond‐breeding amphibians from capture data with imperfect detection.

Behavioral responses of black bears to human presence and infrastructure in Yosemite National Park

The Journal of Wildlife Management, EarlyView.
Using GPS collar data from black bears in Yosemite National Park, we examined how bear spatiotemporal activity in relation to human development shifted during the COVID‐19 park closure in 2020. In the absence of visitors, bears maintained consistent landscape‐scale space use but altered fine‐scale spatial and temporal behaviors.

Coal Mining as a Driver of Land Use and Land Cover Change and Degradation: A Case in Moatize City, Mozambique

Land Degradation &Development, EarlyView.
ABSTRACT Coal remains a major global energy source despite ongoing environmental controversies, particularly, regarding climate change and landscape transformation. This study investigates the spatiotemporal dynamics of land use and land cover (LULC) in the Moatize Coal Basin (MCB), Mozambique, between 1990 and 2024, with a specific focus on land ...

Coherence-coefficient-based Markov random field approach for building segmentation from high-resolution SAR images

Journal of Measurement Science and Instrumentation, 2019
Building segmentation from high-resolution synthetic aperture radar（SAR） images has always been one of the important research issues. Due to the existence of speckle noise and multipath effect, the pixel values change drastically, causing the large ...

Forest Landscape Changes and Ecological Restoration for Sustainable Land Systems

Land Degradation &Development, EarlyView.
ABSTRACT This study investigates forest landscape changes and ecological restoration in Sichuan Province, China, to assess their contribution to sustainable land systems under climate stress. A theory‐guided multistage framework was applied to link Landsat‐based change detection, landscape metrics, habitat quality assessment, soil‐retention analysis ...
