Genomics‐informed management of ex situ populations
Conservation Biology, EarlyView.Abstract The European Association of Zoos and Aquariums (EAZA) manages insurance populations for hundreds of species through its EAZA ex situ programs (EEPs). EEPs help safeguard against extinction in the wild and provide source populations for genetic rescue programs.

Conservation Biology, EarlyView.Abstract The sustainability of area‐based conservation initiatives depends on their value to society. Conservation often focuses inside protected areas, but the impacts of protected areas beyond their boundaries (spillovers) are critical for their social license.

Pest‐preservation paradox among insects
Conservation Biology, EarlyView.The pest‐preservation paradox is a non‐binary perspective that insects range from those that are harmful and requiring management on the one side, to those requiring conservation intervention on the opposite end of the spectrum. Importantly, the vast majority of insects occur somewhere in the center of the two extremes, and their position along the ...

Gongye shui chuli, 2016 为弥补强疏水性聚偏氟乙烯（PVDF）膜在实际应用中的缺陷，从膜本体及膜表面2个角度入手，阐述了国内外对PVDF膜亲水化改性的主要方法。膜本体改性主要是将膜材料与亲水性聚合物或无机纳米材料共混，从而改善PVDF膜的亲水性能；而膜表面改性则主要是通过表面涂覆改性与表面接枝改性来实现。PVDF膜亲水性的增强，能有效改善膜的抗污染能力，从而大大提高膜的过水通量，并延长其使用寿命。

Synthesis of Pollinator‐Friendly Management in European Protected Areas
Conservation Biology, EarlyView.Effectiveness of pollinator‐friendly management in European protected areas. Abstract Pollinators are important to humans and nature due to their role in ecosystem functioning and services. Research on the effects of pollinator management in protected areas is insufficient compared with that on farmlands and urban areas, potentially hindering ...

Gongye shui chuli, 2019 考察了聚合氯化铝生产废渣改性前后的组分、性质，及其对污泥脱水性能的改善情况。对酸/碱改性含铝废渣的污泥调理效果进行比较，结果表明：酸改性未能明显改善含铝废渣的污泥调理性能；含铝废渣的碱改性最佳条件为1 mol/L Ca（OH）2，改性3 h，废渣投加量为20 g/L，污泥经调理后沉降比、毛细吸水时间及含水率分别由原先的88%、15.7 s、78.74%降至40%、12.9 s、58.67%。扫描电镜显示碱改性含铝废渣的空隙结构更松散。

Methodology to identify ecologically matching areas and its applications in conservation planning
Conservation Biology, EarlyView.Abstract Identifying ecologically matching areas is both challenging and critical for understanding spatial patterns of biodiversity and advancing conservation planning. However, existing approaches often lack spatial flexibility, overlook shape and size constraints, or rely on limited environmental parameters, reducing their effectiveness in real ...

Gongye shui chuli, 2021 以水产业中产生的虾壳为原料进行改性，通过静态吸附实验探究H2O2改性后的虾壳粉对水中U（Ⅵ）的吸附影响因素。结果表明，当U（Ⅵ）溶液pH=3，改性虾壳粉投加量为0.2 g/L，U（Ⅵ）溶液质量浓度为10 mg/L，吸附时间为120 min时，改性虾壳粉对U（Ⅵ）的吸附量达到48.58 mg/g，pH对改性虾壳粉吸附U（Ⅵ）有较大影响。对吸附过程中的动力学分析以及吸附前后的改性虾壳粉的SEM、FTIR等表征结果表明：改性虾壳粉对U（Ⅵ）的吸附过程符合准一级动力学方程和Freundlich吸附等温模型 ...

Early outcomes of England's new biodiversity offset market
Conservation Biology, EarlyView.Abstract Nature markets are being operationalized as a tool to address the biodiversity finance gap and achieve global biodiversity targets. However, there is limited understanding of how the outcomes of these markets align with biodiversity targets.

Gongye shui chuli, 2017 用硝酸钙和氯化镧对磁铁矿进行改性，考察不同初始浓度、pH、作用时间对含磷废水的吸附效果，进而分析其吸附等温线及动力学特性。结果表明：Langmuir等温吸附方程能很好地描述其等温吸附特性，未改性、硝酸钙改性、氯化镧改性的磁铁矿对磷的吸附饱和量分别为0.068、0.409、2.157 mg/g；未改性、硝酸钙改性、氯化镧改性的磁铁矿分别在pH为12、pH为8~12、pH为4~10时，对磷的吸附效果较好；氯化镧改性磁铁矿对磷的去除率达95%以上且其吸附过程符合二级吸附动力学方程。
