Deep learning‐based super‐resolution reconstruction and improved YOLOv9 for efficient benthos detection: a case study at Lake Hamana, Japan

Remote Sensing in Ecology and Conservation, EarlyView.
This study presents a UAV‐based framework that integrates deep learning‐based super‐resolution reconstruction and an enhanced YOLO detector to improve centimetre‐scale benthic organism monitoring. Using hermit crabs in Lake Hamana, a coastal lagoon in Japan, as a case study, the method substantially enhanced small‐object detection performance ...

An Islamic Perspective on the Sustainable Development Goals: Exploring Key Challenges From the Ravi Riverfront Urban Development Project

Sustainable Development, EarlyView.
ABSTRACT Projects are typically viewed as mechanisms for delivering products and services; however, this study examines projects from the distinct perspective of grand challenges (GCs). The selected case is the Ravi Riverfront Urban Development Project in Lahore, Pakistan—a grand challenge project (GCP).

Sargassum Lung Syndrome: Air Flow Obstruction and Bronchial Inflammation Are Observed After Prolonged Exposure to Sargassum Gas Emissions in the Eastern Caribbean

Environmental Toxicology, EarlyView.
ABSTRACT Sargassum inundation of Caribbean and American shorelines is a growing environmental hazard. Hydrogen sulfide (H2S) and ammonia (NH3) produced by decomposing Sargassum could be involved in airway obstruction and bronchial inflammation. The study was undertaken to evaluate the effects of exposure to H2S and NH3 gases emitted during Sargassum ...

Modernizing environmental data management for ecological research, management, and conservation at regional scales

Wildlife Society Bulletin, EarlyView.
We developed a web GIS system that delivers geospatial data for Wyoming and the Greater Yellowstone Ecosystem (GYE) using cloud‐optimized formats and open‐source tools to support regional ecological research and management. Using pronghorn as an example, we combined observed locations with environmental covariates from our geospatial library to map ...

Accuracy assessment of DSM in mountainous forest areas generated from GF-7 stereo images assisted by ATLAS/ICESat-2 [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
The successful launch of the GaoFen-7 (GF-7) satellite has made it possible to achieve sub-meter-level three-dimensional mapping. However, most current studies focus on accuracy evaluating of GF-7 stereo mapping in bare land, and less on its performance ...

Rapid loss, and slow recovery, of coral reef structural complexity resulting from a prolonged marine heatwave

Journal of Animal Ecology, EarlyView.
Using Structure‐from‐Motion photogrammetry in a longitudinal study, we show that although coral reef habitat complexity had declined significantly by the end of the most prolonged tropical marine heatwave on record, no further losses were detected and 3 years later the reef had begun to recover this critical ecosystem function.
