Factors that shape large‐scale gradients in clonality
Journal of Biogeography, Volume 50, Issue 5, Page 827-837, May 2023., 2023 Abstract Aim Many plant species reproduce clonally. However, ecologists still have much to learn about the factors that shape large‐scale patterns in plant clonal growth and reproduction, especially in the southern hemisphere. We addressed this knowledge gap by quantifying relationships between reproductive mode and a suite of plant characteristics and

Evident but context‐dependent mortality of fish passing hydroelectric turbines
Conservation Biology, Volume 36, Issue 3, June 2022., 2022 Abstract Globally, policies aiming for conservation of species, free‐flowing rivers, and promotion of hydroelectricity as renewable energy and as a means to decarbonize energy systems generate trade‐offs between protecting freshwater fauna and development of hydropower. Hydroelectric turbines put fish at risk of severe injury during passage. Therefore,

Journal of Ecology, Volume 110, Issue 1, Page 97-116, January 2022., 2022 In the BEF‐China experiment, metabolomics samples were collected from four different species and three organs (a). The metabolomes are species and organ specific (b), and the metabolome specificity is attributed to different chemical classes (c). Tree species diversity affects the metabolome composition (d), but more controlled interaction experiments ...

Shuitu Baochi Xuebao, 2022 为了探明西南地区长期不同施肥处理对稻麦轮作紫色土有机碳组分和碳循环相关水解酶活性的影响,依托重庆北碚29年稻麦轮作紫色土长期定位试验,选取不施肥(CK)、单施氮磷钾肥(NPK)、有机无机配施(NPKM)、秸秆还田配施含氯化肥[(NPK)ClS]和秸秆还田配施无机肥(NPKS)5个处理,测定土壤各组分有机碳含量及与土壤碳循环相关的水解酶活性并分析两者间的相关性。结果表明:长期施肥(NPK、NPKM和NPKS)显著提高土壤总有机碳和不同组分有机碳含量,各施肥处理土壤总有机碳含量较CK提升11.6%~40.2%

Shuitu Baochi Xuebao, 2004 不同开垦年限黑土土壤有机碳及其组分含量变化的研究结果表明:土壤开垦前50年,黑土耕层及犁底层总有机碳及其组分含量下降迅速,土壤有机碳的氧化稳定性系数变化强烈。黑土开垦130年后,有机碳及各组分含量基本上处于相对稳定状态。黑土耕作200年,耕层总有机碳含量损失幅度约1.76%～24.81%。有机碳组分中,FA-C受开垦年限影响相对较小,Hu-C受开垦年限影响最大。

Shuitu Baochi Xuebao, 2022 为探究增施有机肥对盐碱土壤有机碳氮组分和微生物群落的影响,以2018年开始的黄河三角洲盐碱垦殖区小麦—玉米轮作样地为研究对象,通过分析3种处理(普通化肥CN、化肥+猪粪有机肥PCOF和不施肥CK)下土壤有机碳氮组分含量和微生物群落对增施有机肥措施的响应,以期为黄河三角洲盐碱地改良和农业可持续发展提供理论依据。结果表明:(1)肥料的投入对盐碱土壤起着积极促进作用,增施有机肥与单施化肥相比,土壤氮磷钾等基础养分含量分别显著提高15.6%,251.7%,65.2%(p＜0.05),耕层结构得到改善。(2 ...

Rare Metals, EarlyView.ABSTRACT The development of efficient and stable bifunctional catalysts remains a key challenge for green hydrogen production via electrochemical water splitting. In this study, a bimetallic Mo/Fe‐doped CoP2 nanoleaf array anchored on carbon cloth (Mo, Fe‐CoP2@CC) was synthesized from zeolitic imidazolate framework‐L (ZIF‐L) via an ion‐exchange and low‐
