Development and Research Progress of the ‘Land‐Based Container + Ecological Pond’ Recirculating Aquaculture Model in China

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
This review systematically examines China's Land‐based Container + Ecological Pond (LCEP) recirculating aquaculture model. It synthesizes the system's development, technical principles, and research progress, highlighting its significant resource savings (>75% land, >90% water) and high‐density production capabilities. The analysis critically evaluates

Impacts of climate change on Tibetan lakes: patterns and processes [PDF]

open access: yes, 2018
High-altitude inland-drainage lakes on the Tibetan Plateau (TP), the earth’s third pole, are very sensitive to climate change. Tibetan lakes are important natural resources with important religious, historical, and cultural significance.

Mid-late Holocene temperature and precipitation variations in the Guanting Basin, upper reaches of the Yellow River [PDF]

open access: yes, 2018
The reconstruction of prehistoric temperature and precipitation variations in the upper reaches of the Yellow River is essential for understanding the cultural evolution of the region, but related information is sparse due to the limitations of the ...

Spatiotemporal Distribution Patterns of Plateau Foxes and Their Lagomorph Prey in Baqing County, Tibet

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Our study suggests pronounced spatiotemporal niche differentiation as a mechanism facilitating two mesocarnivores' coexistence, and enhances our understanding of the mechanisms underlying sympatric coexistence on the Tibetan Plateau. ABSTRACT Predation by carnivores is a fundamental driver of species evolution, shaping interspecific spatiotemporal ...

Drivers of Dissolved Organic Matter Quality and Concentration in a Mountainous Subarctic Watershed, Yukon, Canada

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 4, April 2026.
Abstract Northern permafrost regions contain vast frozen stores of organic carbon that are vulnerable to thaw and mobilization. While considerable attention has been paid to carbon export from large Arctic rivers, gaps remain in characterizing dissolved organic matter (DOM) quality and export in permafrost influenced catchments that contain a mosaic of

Aggregation of Single Nucleotide Polymorphisms in a Human H5N1 Clade 2.2 Hemagglutinin [PDF]

open access: yes, 2007
The evolution of H5N1 has attracted significant interest 1-4 due to linkages with avian 5,6 and human infections 7,8. The basic tenets of influenza genetics 9 attribute genetic drift to replication errors caused by a polymerase complex that lacks a ...

Realm Specific Adaptations Lead to Contrasting Global Patterns in Submerged and Emergent Aquatic Plant Height

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 4, April 2026.
ABSTRACT Aim This study aims to evaluate whether the trait–environment relationships known for terrestrial plant height extend to freshwater macrophytes, and to identify the primary environmental factors influencing global height patterns in emergent and fully submerged aquatic plants. Location Global.

Mechanisms and Applications of Impurity-Driven Surface Modification in Magnesium Sulfate Crystallization

open access: yesCrystals
Impurities significantly constrain the production of high-purity magnesium sulfate crystals, essential for advanced magnesium-based materials. Sodium–magnesium co-precipitation affects the crystals’ purity and surface smoothness, with NaCl embedding into
