Effects of mowing plus waterlogging on germination and seedling growth of Spartina alterniflora [PDF]
, 2018 互花米草(Spartina alterniflora)是我国危害最严重的外来入侵植物之一,探索环保、经济、有效地防治互花米草的技术对保护我国海滩生态环境具有重要意义。本研究通过人工气候室(20~25℃)的盆栽实验,研究刈割与淹水对互花米草萌发和幼苗生长的影响。实验持续4个月,对互花米草地上部分进行了2次刈割,首次刈割是在互花米草生长季结束时,3个月后进行第二次刈割。首次刈割后持续淹水至实验结束,淹水处理设计0、5、10、20 cm四个淹水深度。首次刈割后各淹水处理互花米草根茎上迅速萌发克隆苗 ...

Functional Ecology, Volume 40, Issue 5, Page 1428-1442, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometric imbalance caused by nitrogen (N) deposition typically exacerbates phosphorus (P) limitation in plants. However, it remains unclear whether this effect extends to soil microbes, particularly those in the rhizosphere.

, 2014 四川冬水田的发展史大致可分为清代的兴起与扩展,民国的继承与发展,新中国的改造与缩减三大阶段。水稻种植规模的大小、劳动生产率的高低、水利设施的多少均是影响冬水田发展的因素之一。以往提高农业产出的是改造冬水田的动因;现今提倡恢复冬水田又是出于其水利、生态湿地价值的考虑。冬水田作为一项大规模的水利工程,其之于四川农业 ...

土壤呼吸作用时空动态变化及其影响机制研究与展望. [PDF]
, 2009 测定不同陆地生态系统土壤呼吸速率及其时空波动,阐明其影响因子,对于全球碳素平衡预算和全球变化潜在效应估计是最为基本的数据。然而,有关土壤呼吸作用变异性及其影响因素的知识仍存在局限性,一些关键的过程和机制还有待阐明。该文综述了近年来土壤呼吸作用时空动态规律、影响机制和模拟方面的研究进展,指出环境因子和生物因子共同驱动着土壤呼吸作用的时间动态变化;土壤呼吸作用在不同时间尺度上还具有明显的空间异质性,这主要是植被覆盖、根系分布、主要的环境因素和土壤特性空间分布的异质性造成的 ...

Functional 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 ...

Functional Ecology, Volume 39, Issue 8, Page 2149-2169, August 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants assemble beneficial rhizosphere microbiomes through a ‘cry for help’ mechanism upon pathogen or insect herbivore attack. The arbuscular mycorrhizal fungi (AMF) can influence the composition of microbial communities in the plant rhizosphere. However, their impacts
