Monitoring surface moisture changes using NDWI and extended indices: a case study of Suyahu Reservoir

Shuili Shuiyun Gongcheng Xuebao
Based on the differential reflectance of surface moisture in the green and near-infrared bands observed via remote sensing, this study explores the use of the Normalized Difference Water Index (NDWI) and its extended indices to monitor surface moisture ...

Identification of initial vegetation and habitat changes in small temperate fens using remote sensing

Remote Sensing in Ecology and Conservation, EarlyView.
Temperate fens with only incipient, subtle signs of deterioration can be reliably identified using Sentinel‐2 and aerial imagery, which sensitively detect early productivity‐related structural changes. Abstract Small temperate fens rank among the most endangered habitats in temperate Europe.

Climate‐Driven Mangrove Dieback and Recovery: A Case Study in Albert and Leichhardt Rivers, Australia

Remote Sensing in Ecology and Conservation, EarlyView.
Cycles of dieback and recovery drove mangrove forest dynamics at the Albert and Leichhardt Rivers (Gulf of Carpentaria, Queensland, Australia) over 36 years (1987–2023). Landward margins were the most affected by reduced tidal inundation when the alignment of low lunar declination suppressed tidal range and extreme El Niño phases lowered mean sea level.

Mapping Coastal Dynamics Induced Land Use Change in Sandwip Island, Bangladesh

Remote Sensing
Evaluating satellite water extraction indices, particularly for coastal environments, guarantees that satellite-derived water maps are as accurate and functional as possible, notwithstanding the unique complexities these areas present.

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

Remote 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.

Mapping mosquito larval densities and assessing area vulnerable to diseases transmission in Nile valley of Giza, Egypt

Egyptian Journal of Remote Sensing and Space Sciences, 2022
Diversity and abundance of mosquito larvae have significant impact on the dynamics of disease transmission. In the present study, remote sensing (RS) technology integrated with field survey and spatial analyses were utilized to map mosquito breeding ...

Improved Cerrado Wetland Mapping Through Seasonal Moisture Metrics, Terrain Information and Semantic Segmentation

Remote Sensing in Ecology and Conservation, EarlyView.
Brazil's Cerrado valley wetlands—swamp savanna and gallery forest—are highly important for the biome's water cycle and carbon storage and are susceptible to degradation from the impacts of land use expansion and the climate crisis. In support of their detailed monitoring and assessment, we developed and tested a transferable mapping approach that ...

‘Using anuran community diversity and Pseudacris crucifer to predict landscape quality across a land use gradient'

Wildlife Biology, EarlyView.
As human‐modified landscape and climate changes proliferate, maintaining biodiversity and understanding the function and quality of available habitat is imperative. As anurans (frogs/toads) such as Pseudacris crucifer, can be an indicator species of habitat quality and ecosystem productivity, studying the anuran community in a mixed‐land use region ...

Monitoring of Inland Surface Water Quality Using Remote Sensing on the Example of Wigry Lake

E3S Web of Conferences, 2018
The study examines how LANDSAT images can be used to monitor inland surface water quality effectively by using correlations between various indicators. Wigry lake (area 21.7 km2) was selected for the study as an example. The study uses images acquired in

Fine‐scale spatio‐temporal niche partitioning enables coexistence of wild ungulates and livestock in a resource‐limited Himalayan landscape, India

Wildlife Biology, EarlyView.
Understanding how wild ungulates share space with domestic livestock is central to conservation planning in Himalayan multi‐use landscapes. This study focuses on multi‐axis niche relationships among six wild ungulates: hangul Cervus hanglu hanglu, Kashmir musk deer Moschus cupreus, Himalayan goral Naemorhedus goral, kashmir markhor Capra falconeri ...
