Strategies in Ericaceae to acquire phosphorus in phosphorus‐impoverished habitats in the southwest Australian biodiversity hotspot

open access: yesFunctional Ecology, Volume 39, Issue 10, Page 2889-2904, October 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In the Southwest Australian Biodiversity Hotspot, the greatest plant species diversity tends to occur on the most phosphorus (P)‐impoverished soils. Many plant species in this P‐impoverished environment release root carboxylates that mobilise soil P which is a more ...

The preparation and basic researches of blood vessels with anticoagulant and endothelial functions [PDF]

open access: yes, 2017
小口径血管一般是指直径小于6mm的血管,人工血管移植物已经被大量地应用于临床实践中,目前临床上常用的主要有自体血管移植物、异体血管移植物和人工合成的高分子材料血管移植物等3大类血管移植物。其中前两类由于来源有限与异体排斥反应局限了其临床应用,而高分子合成材料制成的人工血管已在大口径血管移植方面取得了比较大的进展,但在小口径血管移植方面一直没有取得突破性进展,究其原因主要还是由于血管材料的内皮化功能欠缺,机械性能不如天然血管等,故本文采取将细胞种植于人工材料表面的方法,制备人源性细胞外基质 ...

Using online reports of seahorse seizures to track their illegal trade

open access: yesConservation Biology, Volume 39, Issue 5, October 2025.
Abstract Illegal wildlife trade (IWT) is a persistent and extensive threat to global biodiversity. Hundreds of marine fish species are subject to regulation under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), but it is unclear how much protection species gain from CITES because information on marine fish ...

Assessing limits of sustainable seed harvest in wild plant populations

open access: yesConservation Biology, Volume 39, Issue 5, October 2025.
Abstract Seed harvesting from wild plant populations is key for ecological restoration, but it may threaten the persistence of the source populations. Consequently, several countries have set guidelines limiting the proportions of harvestable seeds. However, these guidelines are inconsistent and lack a solid empirical basis.

立体绿化在景观中的表现 [PDF]

open access: yes, 2014
随着城市化进程的加快,人口从乡村向城市集中,人口密度逐渐超出了城市所能承受的限量,城市人口增长带来城市配套设施的大量建设,使城市变成钢筋混泥土森林,污染蔓延,包括噪声、空气、白色垃圾污染等等。在这样的背景下,景观立体绿化成为城市景观建设中一大趋势,城市的美化要以可持续发展、改善生活环境建设为目标,而立体绿化更是景观绿化中的一大创意点,立体美化城市景观,创造优美,舒适,健康的人居环境成为新一代人的努力目标,更在城市中起到重要的装饰作用 ...

Exploring the importance of aromatic plants' extrafloral volatiles for pollinator attraction

open access: yesNew Phytologist, Volume 248, Issue 2, Page 517-528, October 2025.
Summary Aromatic plants occur in many plant lineages and have widespread ethnobiological significance. Yet, the ecological significance and evolutionary origins of aromatic volatile emissions remain uncertain. Aromatic emissions have been implicated in defensive interactions but may also have other important functions.

黄土高原半湿润农作区春玉米土壤环境和产量对种植方式的响应

open access: yesShuitu Baochi Xuebao, 2019
为探讨黄土高原半湿润易旱区不同种植方式对土壤水热环境及春玉米生长动态变化,于2017-2018年在甘肃华亭农技推广中心开展田间定位试验,设平地全膜覆盖(WM)、平地半膜覆盖(HM)、隔沟覆膜垄播(MRM)、全膜双垄沟播(WRF)、秸秆覆盖(SM)和露地平播(CK)6种种植方式,测定分析了春玉米各生育时期土层剖面水热状况、作物生长特征及收获期作物产量与构成因子。结果表明:覆盖种植方式对土壤温度的调节主要表现在苗期,地膜覆盖处理较CK具有增温效应,全生育期土壤平均增温1.44~2.62 ...

Natural Regeneration Outperforms Active Restoration in Enhancing Biodiversity and Biomass Along an Altitudinal Gradient in Chinese Savanna Ecosystems 中国稀树灌草丛中自然恢复对生物多样性与生物量的提升效应优于人工恢复

open access: yesIntegrative Conservation, Volume 4, Issue 3, Page 491-502, September 2025.
The impact of various restoration strategies on biodiversity and biomass in degraded savannas was evaluated across different elevation gradients. Natural regeneration co‐benefits the increasing in biodiversity and biomass in savannas, while active restoration exhibits altitude‐dependent efficacy and lower biomass accumulation capacity.
