Migratory shorebirds traveling the East Asian–Australasian Flyway face systemic policy fragmentation and habitat disconnection between China (coordination challenges and renewable energy conflicts) and Australia (federal governance fragmentation). This study proposes a transboundary conservation framework to fill this gap.

土壤盐分和含水量的空间变异性及其CoKriging估值——以黄河三角洲地区典型地块为例
以黄河三角洲地区典型地块为研究区,运用经典统计学和地统计学相结合的方法研究了不同深度土层盐分和含水量的空间变异特征。结果表明:研究区土壤盐分和含水量普遍较高,土壤表层积盐作用明显;各层土壤盐分均属于中等变异强度,土壤含水量除表层为中等变异强度外,其余各层为弱变异强度;受结构性因素和随机性因素的共同作用,各土层盐分和含水量均具有中等的空间相关性。对Kriging插值结果分析表明,研究区各土层盐分和含水量在一定的范围内均存在着空间上的相关性和变异性,表层土壤盐分和含水量的空间分布主要受微地形和气候条件的影响,

ABSTRACT A facile coprecipitation‐pyrolysis strategy was employed to fabricate Cu/Co nanoparticles (NPs) embedded in nitrogen‐doped carbon matrices (Cu/Co@N‐C) through the carbonization of CuCo‐MOF precursors. Moreover, monometallic counterparts of Cu@N‐C and Co@N‐C were also prepared via carbonization of bimetallic CuZn‐MOF and CoZn‐MOF, respectively.

Dual‐Layer Solid Electrolyte Interphase Enables Effective Suppression of Lithium Dendrites
ABSTRACT The heterogeneous solid electrolyte interphase (SEI) at the Li metal anode often leads to slow and uneven Li+ flux, causing severe Li dendrite growth. Herein, we combine X‐ray photoelectron spectroscopy and cryogenic transmission electron microscopy to demonstrate that a dual‐layer SEI, consisting of an inorganic inner layer and an organic ...

ABSTRACT Although alloy‐based materials present potential for peroxymonosulfate (PMS) activation, metal ion leaching remains severely restricted during the pollution degradation process. Herein, the porous carbon‐supported Fe–Cu alloy derived from industrial copper slag was prepared to remove the organic pollutants from wastewater while inhibiting the ...

ABSTRACT Groundwater depletion is a major challenge in semiarid, hard‐rock regions where irrigation demands often exceed natural recharge. This study evaluates the effectiveness of farm‐scale recharge pits as a local, supplementary, and community‐managed groundwater recharge solution in the Dharta catchment of Rajasthan, India. Alongside check dams and

Structured machine learning modeling to support conservation of deep‐sea benthic biodiversity
Abstract Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim).

Mechanoluminescent Mixed‐Anion Borate Sr2B5O9Cl:Eu for Dynamic Anticounterfeiting
ABSTRACT Mechanoluminescence (ML)—the emission of light in response to mechanical stimuli—offers a direct and visually intuitive route for transducing mechanical information into optical signals. Herein, we report a mixed‐anion strategy to prepare mixed‐anion borate Sr2B5O9Cl:Eu phosphors through a facile, low‐temperature, and ambient‐atmosphere solid ...
