Coastline Fractal Dimension of Mainland, Island, and Estuaries Using Multi-temporal Landsat Remote Sensing Data from 1978 to 2018: A Case Study of the Pearl River Estuary Area

Remote Sensing, 2020
The Pearl River Estuary Area was selected for this study. For the past 40 years, it has been one of the most complex coasts in China, yet few studies have analyzed the complexity and variations of the area’s different coastlines.

Multi‐objective optimization of reservoir refill operate considering energy storage and hydrological conditions

River, EarlyView.
Abstract Optimizing reservoir refill operation rules is crucial for enhancing reservoir sustainability and resilience. This study proposes a refill operation model designed to derive optimal refill guide curves by considering flood risk prevention, maximum storage levels, and the combined benefits of hydropower generation and energy storage.

Trends in thunderstorm days, lightning activity, squalls and the environmental factors in Hong Kong

Weather, EarlyView.
This study analyses trends in Hong Kong's convective weather using long‐term observer‐based and shorter‐term instrument‐based data. Annual thunderstorm days increased significantly by 1.9 days decade−1 in 1947–2024, notably in June–September, consistent with increasingly favourable warm‐season environments for thunderstorms.

Phosphorus availability shapes size structure, co-occurrence patterns and network stability of surface microeukaryotic plankton communities in an urbanized estuarine ecosystem

Ecological Indicators, 2023
The size structure of microeukaryotic plankton communities exerts a fundamental control on marine ecosystem functions, such as food web dynamics and element flows. The global expansion of nitrogen (N) and phosphorus (P) nutrient pollutants into estuaries

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

Integrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...
