Nutritional and Physiological Markers Are Mediated by Seasonality and Forest Access in Captive Coquerel's Sifakas 圈养科氏冕狐猴 (Coquerel's Sifakas) 的营养和生理指标受季节性和森林通道的影响

open access: yesIntegrative Conservation, Volume 4, Issue 4, Page 652-664, December 2025.
We profiled nutritional and physiological markers in captive sifakas, endangered primates from Madagascar, managed in expansive, non‐native forest enclosures. Variation in many markers reflects freely foraged diets and the energy required to maintain homeostasis under more naturalistic conditions.

Factors influencing fine roots decomposition rates in response to nitrogen addition vary across root characteristics

open access: yesFunctional Ecology, Volume 39, Issue 12, Page 3504-3516, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Nitrogen (N) deposition strongly affects litter decomposition and nutrient release, thereby reshaping carbon cycling in terrestrial ecosystems. Although most studies have focused on above‐ground litter, the effects of N addition on fine root decomposition and their ...

氮肥后移对强筋小麦氮素积累转运及籽粒产量与品质的影响

open access: yesShuitu Baochi Xuebao, 2018
为探索强筋小麦施用氮肥的合理基追比模式,在山西中部麦区水地小麦田,研究了氮肥基施、拔节期追施和孕穗期追施的不同比例(10∶0∶0,7∶3∶0,7∶2∶1,6∶4∶0,6∶2∶2,5∶5∶0,5∶3∶2)对强筋小麦CA0547氮素积累转运及籽粒产量与品质的影响。结果表明:(1)适当追氮对强筋小麦CA0547氮素与干物质积累转运及产量品质有显著的调节效应。(2)追氮能显著提高小麦拔节期后的含氮量,提高花前氮素转运量和花后氮素积累量,促进氮素向籽粒中的累积,同时增加花前干物质转运量和花后干物质积累量 ...

Laser‐guided thin‐film self‐rolling for asymmetric small‐scale swimmers

open access: yesRare Metals, Volume 44, Issue 8, Page 5607-5620, August 2025.
Graphical abstract AbstractSmall‐scale robots are promising miniaturized devices in biomedicine. Thin‐film self‐assembly is a commonly used strategy to fabricate tubular small‐scale robots. However, the existing methods have limitations like complex manufacturing processes and limited control of self‐assembly behavior.

China's Eco‐Civilisation, Climate Leviathan, and Hobbesian Energy Transition

open access: yesAntipode, Volume 57, Issue 3, Page 830-861, May 2025.
Abstract Scholars have hitherto tended to theorise China's ecological civilisation project either as a form of environmental authoritarianism or as a vision of eco‐socialism. This paper contributes to the conversation by conducting a textual analysis of Chinese scholarly discussions on eco‐civilisation.

施硫对不同筋力型品种小麦碳氮运转和产量的影响

open access: yesShuitu Baochi Xuebao, 2007
在大田条件下,研究了不同施硫水平对不同筋力类型品种植株C-N积累与转运规律和籽粒产量及蛋白质、淀粉含量的影响.结果表明,施硫处理提高了两品种成熟期单茎籽粒重和籽粒氮素的积累量和开花前营养器官贮存干物质和氮素的转运量以及转运干物质和氮素对籽粒重和籽粒氮素积累的贡献率,与不施硫对照(S0)相比,每1 hm2施20 kg纯S(S1)处理能明显提高两品种的产量构成因素,显著提高籽粒产量,两品种分别增产10.69%和9.78%,同时极显著地提高了籽粒蛋白质和淀粉含量.大量施用硫肥(100 kg/hm2 ...

Advances in bacterial lignin degradation and transformation mechanisms(细菌降解木质素与转化机制研究进展)

open access: yes浙江大学学报. 农业与生命科学版
Lignin, the second most abundant biomass resource in the plant kingdom after cellulose, is the most plentiful renewable aromatic polymer in nature. However, its complex and recalcitrant structure greatly hinders its efficient utilization.

生物炭对铜矿区污染土壤微生物活性及香根草富集铜、镉、铅的影响

open access: yesShuitu Baochi Xuebao, 2022
矿区土壤易发生重金属污染,是土地资源利用和维护的一大难题。以铜矿区污染土壤为研究对象,按质量比添加0,1%,2%,4%,10% (w/w)的生物炭,进行香根草室内盆栽试验。研究添加生物炭对土壤pH和微生物活性、香根草富集与转运重金属的影响,探明重金属形态含量与生物炭、微生物活性的相关性,旨在为生物炭与香根草联合修复矿区重金属污染土壤提供理论参考。结果表明:生物炭的添加能提高土壤pH,显著提高土壤FDA水解酶、蔗糖酶和脲酶活性,显著促进土壤基础呼吸,但对土壤微生物量碳无显著影响 ...

Conservation Gap Within a Nature Reserve: A Case Study in the Biodiversity Hotspot of Rare and Endangered Plants at the Southern Gaoligong Mountains 高黎贡山南段稀有濒危植物保护空缺分析

open access: yesIntegrative Conservation, Volume 4, Issue 1, Page 71-84, March 2025.
Gaoligong Mountain is home to a large number of rare and endangered species, but the effectiveness of conservation measures in the Gaoligong Mountain Nature Reserve remains uncertain. We predicted the potential distribution areas of 361 rare and endangered wild plants in southern Gaoligong Mountain under current and future climate change scenarios and ...

Moving beyond the pathology of policies pushing species toward extinction: The case of spectacled flying foxes in Australia 摆脱将物种推向灭绝的政策症候——以澳大利亚眼镜狐蝠为例

open access: yesIntegrative Conservation, Volume 3, Issue 2, Page 87-103, June 2024.
Some extinctions can be prevented if impediments to protection of threatened species are overcome. Policies and practices have failed endangered species and biodiversity conservation is fraught with impediments such as rhetorical adoption, policy dismantling, circumvention of legislative obligations, and deliberate ignorance of scientific evidence ...
