Pixels and Patterns in the Sand: Decoding Coastal Dune Habitats With Multi‐Resolution CNNs

Journal of Vegetation Science, Volume 37, Issue 5, September/October 2026.
Coastal dune habitats are small, fragmented, and challenging to map. We tested convolutional neural networks (CNNs) on an Italian coastal dune system, comparing four remote sensing datasets: UAV, airborne, Google Earth, and WorldView‐3 satellite. Mapping accuracy dropped sharply with coarser spatial resolution, while adding spectral bands mostly ...

Using Drones for Large Mammal Monitoring

Mammal Review, Volume 56, Issue 3, September 2026.
Drones were used to obtain video data on animals and locations and distance from the midline was automatically determined by our pipeline so that the input for Distance sampling is generated. ABSTRACT Introduction The emergence of drones has profoundly transformed the field of large mammal monitoring, offering unprecedented capabilities for data ...

Geophysical update of the diameter of the Zhamanshin impact structure, Kazakhstan

Meteoritics &Planetary Science, Volume 61, Issue 9, Page 2284-2302, September 2026.
Abstract The rim of the 0.9‐Ma‐old Zhamanshin impact crater in Kazakhstan is considered to be almost completely exposed via a series of hills surrounding a central flat area, indicating an apparent diameter of 14 km. This would make Zhamanshin the second largest impact crater of the Quaternary period. However, the overall geometry of these hills is not

Differential growth dynamics of common salt marsh species Spartina alterniflora and Juncus roemerianus under varied sediment amendments

Restoration Ecology, Volume 34, Issue 7, September 2026.
Abstract Introduction Many coastal wetlands are at high risk of degradation or loss due to sea‐level rise. Restoration techniques for maintaining coastal marshes are paramount, with thin‐layer placement (TLP) emerging as one feasible solution. Despite TLP's utilization, additional research is needed on species‐ and sediment‐specific responses ...

Smart Routing Framework for Urban Curbside Scanning: A Framework for Time‐Optimized and Spatially Representative Data Collection

Transactions in GIS, Volume 30, Issue 6, September 2026.
ABSTRACT Urban curbside monitoring requires routes that balance travel efficiency with representative sensing coverage. This study develops a reproducible GIS‐based routing framework for vehicle‐based residential curbside scanning. The framework integrates local‐residential target link identification, deterministic farthest point sampling, directed ...
