Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Root activity creates unique microbial hotspots in the rhizosphere by influencing the metabolic activities of surrounding soil microorganisms, profoundly regulating the dynamics of soil organic carbon (SOC). However, how root economic strategies affect the formation and

Using customs data to understand overlooked trade in non‐CITES birds between Africa and Asia
Conservation Biology, EarlyView.Abstract The international trade in live birds poses risks to animals, people, and biodiversity. To effectively mitigate these risks, decision‐makers require information on the volume, dynamics, and direction of trade. Despite Africa once being the largest exporter of birds by region, very little data exist on recent trade in live birds not listed on ...

Risks of concealing environmental degradation
Conservation Biology, EarlyView.Abstract Current practice seeks to conceal the visual impact of land‐use change (i.e., development). Six percent of development impact assessments in Australia and 14% of the World Bank's assessments recommend visual impact mitigation. This mitigation results in, for example, vegetated buffer strips alongside cleared agricultural areas and earthen ...

Shuitu Baochi Xuebao, 2003 环县地处陇东黄土高原北部,面积9 326 km2,其天然植被为森林草原与荒漠草原过渡地带.通过对40年前后天然草地植被的比较研究,得出40年来在自然和人类共同作用下,天然草地植被演变的结果是:天然分布的原生植被基本被天然次生植被所替代,植被组成更趋于简单化,天然生长的乔木和灌木群系消失,地带性顶极植被类型短花针茅、长芒草和大针茅群系消失,小面积分布的部分群系消失,各群系中次优势种发生了改变,植被的生态学特征发生变化,生态功能显著降低,天然草地植被严重退化,造成这一结果的主要原因是人类的垦荒 ...

Uncovering correlates of decline and critical refuges for a threatened terrestrial mammal
Conservation Biology, EarlyView.Abstract Globally, the geographic ranges of numerous species are contracting. Identifying spatiotemporal patterns of threat impact can illuminate why species decline in some parts of their range but persist in others. We developed a correlative approach to identify species’ response thresholds and locate ecological refuge areas associated with ...

Shuitu Baochi Xuebao, 2017 通过室内水槽模拟冲刷试验，研究缓坡坡降1.4%、流量0.6～1.8 L/s、非淹没条件下，植被类型（柔性植被、刚性植被）和植被配置格局（棋盘状格局、长条状格局、带状格局）对坡面流水深、流速、流态、达西阻力系数等水动力学特性的影响，探究其规律。结果表明：（1）与裸坡相比，植被具有雍水缓流作用，水深雍高1.4～2.8倍，流速延缓31%～65%，植被格局较植被类型作用更为明显，其中柔性植被、带状格局雍水效果最好。（2）坡面流态指数m显示刚性植被、棋盘状格局条件下水流紊动性最强，而坡面综合指数k显示刚性植被 ...

Effects of restoration practices on biodiversity in temperate and boreal forests
Conservation Biology, EarlyView.Abstract Several restoration practices are used to mitigate and compensate for the negative effects of large‐scale forestry on biodiversity in temperate and boreal forests. A comprehensive synthesis of the benefits of these practices across taxa is missing. We conducted a systematic review and meta‐analysis on this topic.

International Journal of Applied Linguistics, EarlyView.ABSTRACT This study examines how foreign language teachers’ beliefs about the medium of instruction and translanguaging evolve over time by revisiting three in‐service teachers twelve years after their initial interviews. Using a qualitative longitudinal design, the study traces how translanguaging was initially framed as pedagogically deficient but ...

New Phytologist, EarlyView.Morphospace position and phylogenetic placements of Trimeriantha monopolyada. Summary Floral structure is a key aspect of angiosperm diversity. Recent research revealed that significant floral disparity was already present in the Cretaceous. However, our understanding of early floral diversity remains limited, as it is directly dependent on the fossil ...

Shuitu Baochi Xuebao, 2021 植被覆盖度变化及其与驱动因子关系的研究是开展大规模植被恢复效益评估的基础，而目前对西南槽谷地区植被绿化的时空变化模式及其驱动因素的认识并不明晰，不利于进一步生态建设。基于2000—2018年西南槽谷区NDVI、气温、降雨、DEM、土地覆被和人口密度数据，应用线性趋势回归分析和Hurst指数分析等方法以及地理探测器模型，探究了西南槽谷区植被覆盖的时空变化特征和驱动因素，预测未来变化趋势。结果表明：（1）近19年来NDVI范围介于0.79~0.84，总体呈波动上升趋势，岩溶区植被NDVI （0.003 17/
