Multi‐Scale Drivers of Food‐Water‐Energy Related Ecosystem Services in the Context of Land Degradation: Insights From the Beijing‐Tianjin‐Hebei Agglomeration

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Land degradation poses significant challenges to maintaining food–water–energy (FWE) security, particularly in rapidly urbanizing regions. The ecosystem services (ES) related to FWE are critical for sustainable regional development. Yet, rapid urbanization in the Beijing–Tianjin–Hebei region has altered land use and ecological patterns ...

Evaluation of Sediment Connectivity Indices to Improve the Prediction of the Spatiotemporal Variability of Sediment Yield for a Large River Basin (Wei River, China)

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Sediment connectivity between source areas and the main streams or local sinks is a complex and dynamic process, especially in large basins due to multiple heterogeneities and interactions between connectivity components. Sediment connectivity indices are promising tools to investigate sediment transport, especially in data‐scarce or large ...

Carbon Stock and Environmental Variations of Typical Plantations in Mufu Mountain in Hubei Province, China

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Forest ecosystems play a critical role in the global carbon cycle. As a significant terrestrial carbon sink, plantations exhibit carbon stock patterns that are shaped by tree species composition, stand structure, and environmental conditions. Here, we investigated typical plantation types in the Mufu Mountain, Hubei Province.

Effects of oligotrophication on fish growth: Insights from a mesocosm experiment

open access: yesLimnology and Oceanography, EarlyView.
Abstract Human activities can frequently affect aquatic ecosystems in irreversible ways, with flow regulation and water quality being major concerns. Dams can promote the retention of sediments and nutrients, increase water transparency, and reduce primary productivity, all of which characterize the oligotrophication process.

Experimental droughts in mesocosms reveal a gradient of tolerance in Alpine stream macroinvertebrates

open access: yesLimnology and Oceanography, EarlyView.
Abstract Prolonged droughts, driven by climate change and human pressures on water resources, are increasing in frequency and intensity, particularly impacting Alpine rivers. Benthic macroinvertebrates are one of the most important structural and functional components of Alpine lotic ecosystems.

Frontogenesis by material convergence in an estuary and its adjacent coastal ocean

open access: yesLimnology and Oceanography, EarlyView.
Abstract Surface fronts are common features across the world's oceans, particularly in estuarine and coastal regions where the merging of freshwater and saltwater creates strong density gradients. It has long been documented that fronts in these regions can trap and concentrate various properties such as floating debris, nutrients, larvae, and other ...

Zooplankton diversity in highly urbanized ponds: The role of road salt is not reflected by watershed impervious cover

open access: yesLimnology and Oceanography, EarlyView.
Abstract Urban ecosystems are structured by multiple anthropogenic stressors, yet despite the increasing extent and rate of urbanization worldwide, the ecological consequences of excessive road salt application and other urban phenomena remain poorly resolved.

Optimization of Pulsed Saturation Transfer MR Fingerprinting (ST MRF) Acquisition Using the Cramér–Rao Bound and Sequential Quadratic Programming

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a method for optimizing pulsed saturation transfer MR fingerprinting (ST MRF) acquisition. Methods The Cramér–Rao bound (CRB) for variance assessment was employed on Bloch–McConnell‐based simulated signals, followed by a numerical sequential quadratic programming optimization and basin‐hopping avoidance of local minima ...
