Multiscale Evaluation of Gridded Precipitation Datasets across Varied Elevation Zones in Central Asia’s Hilly Region

Remote Sensing, 2023
The lack of observed data makes research on the cryosphere and ecology extremely difficult, especially in Central Asia’s hilly regions. Before their direct hydroclimatic uses, the performance study of gridded precipitation datasets (GPDS) is of utmost ...

An evaluation of onshore digital elevation models for modeling tsunami inundation zones [PDF]

Frontiers in Earth Science, 2015
A sensitivity study is undertaken to assess the utility of different onshore digital elevation models (DEM) for simulating the extent of tsunami inundation using case studies from two locations in Indonesia. We compare airborne IFSAR, ASTER and SRTM against high resolution LiDAR and stereo-camera data in locations with different coastal morphologies ...

Biogeomorphic Feedbacks Triggered by Mangrove Degradation at the Seaward Margin Accelerate Persistent Vegetation Decline [PDF]

Ecology and Evolution
Mangrove ecosystems are vulnerable to extreme events and sea‐level rise. The present study examined how biological and geomorphological processes interact at mangrove seaward margins (MSM) using remote sensing, field surveys, and elevation monitoring ...

Improved Estimates of Population Exposure in Low-Elevation Coastal Zones of China [PDF]

International Journal of Environmental Research and Public Health, 2019
With sea level predicted to rise and the frequency and intensity of coastal flooding expected to increase due to climate change, high-resolution gridded population datasets have been extensively used to estimate the size of vulnerable populations in low-elevation coastal zones (LECZ). China is the most populous country, and populations in its LECZ grew

Integrating Temporal Vegetation and Inundation Dynamics for Elevation Mapping Across the Entire Turbid Estuarine Intertidal Zones Using ICESat-2 and Sentinel-2 Data

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
High-precision elevation mapping is essential for ecological restoration, marine disaster assessment, and morphodynamic simulation in intertidal zones. Current methodologies are often impeded by an over-reliance on extensive in situ measurements and are ...

Spruce trees have stronger drought sensitivity at low- than high-elevation sites across China’s aridity zones

Global Ecology and Conservation
The ecological relationships between tree growth and climate factors are important for the adaptation, growth prediction, and forest management of tree species against a background of global warming.

Predicting changes in molluscan spatial distributions in mangrove forests in response to sea level rise

Ecology and Evolution, 2022
Mollusks are an important component of the mangrove ecosystem, and the vertical distributions of molluscan species in this ecosystem are primarily dictated by tidal inundation.

Palustrine forested wetland vegetation communities change across an elevation gradient, Washington State, USA [PDF]

PeerJ, 2020
Background Forested wetlands support distinct vegetation and hydrology relative to upland forests and shrub-dominated or open water wetlands. Although forested wetland plant communities comprise unique habitats, these ecosystems’ community structure is ...

Asynchrony among insect pollinator groups and flowering plants with elevation

Scientific Reports, 2020
Mountains influence species distribution through differing climate variables associated with increasing elevation. These factors determine species niche ranges and phenology.
