Abstract Hyphae of arbuscular mycorrhizal fungi (AMF) in soil often form complex mycorrhizal networks among roots of same or different plant species for transfer of nutrients from one plant to another. However, the effect of soil nitrogen (N) availability on nutrient transfer between different plant species via common mycorrhizal networks (CMNs) has not been experimentally examined. In order to quantify

Shifts in chemical and microbiological properties belowground of invader Ageratina adenophora along an altitudinal gradient J. Plant Ecol. (IF 2.7) Pub Date : 2022-01-11 Wei-Tao Li,Yu-Long Zheng,Rui-Fang Wang,Zheng-Ying Wang,Yan-Mei Liu,Xiong Shi,Zhi-Yong Liao,Yang-Ping Li,Yu-Long Feng
Abstract Aims Tropical mountain ecosystems are usually colonized by numerous invasive plant species and represent an ideal “natural laboratory” to study the effects of altitude on plant invasion. The aim of this study was to investigate the soil chemical and microbiological properties along an altitudinal gradient on a mountain colonized by the invader Ageratina adenophora. Methods Rhizosphere soil

Effect of daily salinity fluctuation on the intraspecific interactions of a euhalophyte (Suaeda salsa) along a salinity gradient J. Plant Ecol. (IF 2.7) Pub Date : 2022-01-11 Hua Ma,Li-Juan Cui,Wei Li,Yu Ning,Yin-Ru Lei,Xu Pan,Yi-Fei Wang,Man-Yin Zhang
Abstract Heterogeneity of soil salinity is a prominent environmental characteristic in the intertidal zone of estuaries, affecting the plant growth and the shift of biotic interactions in the salt marsh. This study aims to examine the interactive effects of a salinity gradient and salinity fluctuations on intraspecific interactions of a euhalophyte. We assessed the impact of daily fluctuating salinity

Differences in functional traits among distinct populations of the plant invader Bunias orientalis J. Plant Ecol. (IF 2.7) Pub Date : 2022-01-10 Blaise Binama,Caroline Müller
Abstract Aims Plants that expand their range and become invasive in other areas may shift several functional traits in response to specific environments. However, local conditions at the place of origin may have shaped the functional traits, which may to some extent remain visible in plants growing in new habitats. The present study aimed to explore the trait variation in different plant populations

Drought may be beneficial to the competitive advantage of Amaranthus spinosus J. Plant Ecol. (IF 2.7) Pub Date : 2022-01-09 Youli Yu,Huiyuan Cheng,Shu Wang,Mei Wei,Congyan Wang,Daolin Du
Abstract Aims Drought can affect the growth and soil enzyme activities of invasive alien plants (IAPs). It is imperitive to evaluate the competitive advantage of IAPs compared with that of the native species and the activities of soil enzymes under drought. This study aimed to evaluate the competitive advantage of the IAP Amaranthus spinosus that originated from tropical America compared with the native

Patterns of grassland community composition and structure along an elevational gradient on the Qinghai-Tibet Plateau J. Plant Ecol. (IF 2.7) Pub Date : 2021-12-09 Xin Wang,Jiangling Zhu,Shitao Peng,Tianli Zheng,Zhaoyu Qi,Jianbo Hu,Chengjun Ji
Abstract Aims Grasslands in the Qinghai-Tibet Plateau play an important role in preserving ecological security and high biodiversity in this region. However, the distribution of the composition and structure of plant community and the mechanism by which it maintains itself in this region is still poorly understood. Methods Here, we designed 195 grassland plots in 39 grassland sites along an approximately
