Climate and Land-Use Changes Predicted to Jointly Drive Soil Fungal Diversity Losses in One-Third of North American Coniferous Forests. [PDF]

open access: yesGlob Chang Biol
This study assessed the potential impacts of climate and land‐use change on soil fungal diversity across four North American biomes. We found that climate change typically caused both diversity losses and gains, particularly in coniferous forests and among arbuscular mycorrhizal fungi, whereas land‐use change mainly reduced diversity, especially in ...

Variation in mycorrhizal communities and the level of mycoheterotrophy in grassland and Forest populations of Neottia ovata (Orchidaceae)

open access: yesFunctional Ecology, Volume 37, Issue 7, Page 1948-1961, July 2023., 2023
Read the free Plain Language Summary for this article on the Journal blog. Abstract Orchid mycorrhiza forms unique symbiotic associations between members of the Orchidaceae and multiple ecological guilds of fungi. Because orchids associate with a wide variety of fungi with different ecological functions, they represent an ideal study system to address ...

Uncorrected soil water isotopes through cryogenic vacuum distillation may lead to a false estimation on plant water sources

open access: yesMethods in Ecology and Evolution, Volume 14, Issue 6, Page 1443-1456, June 2023., 2023
Abstract Successful use of stable isotopes (δ2H and δ18O) in ecohydrological studies relies on the accurate extraction of unfractionated water from different types of soil samples. Cryogenic vacuum distillation (CVD) is a common laboratory‐based technique used for soil water extraction; however, the reliability of this technique in reflecting soil ...

Effects of interactions between anthropogenic stressors and recurring perturbations on ecosystem resilience and collapse

open access: yesConservation Biology, Volume 37, Issue 1, February 2023., 2023
Abstract Insights into declines in ecosystem resilience and their causes and effects can inform preemptive action to avoid ecosystem collapse and loss of biodiversity, ecosystem services, and human well‐being. Empirical studies of ecosystem collapse are rare and hampered by ecosystem complexity, nonlinear and lagged responses, and interactions across ...

A new method for broad‐scale modeling and projection of plant assemblages under climatic, biotic, and environmental cofiltering

open access: yesConservation Biology, Volume 36, Issue 2, April 2022., 2022
Abstract There is increasing interestin broad‐scale analysis, modeling, and prediction of the distribution and composition of plant species assemblages under climatic, environmental, and biotic change, particularly for conservation purposes. We devised a method to reliably predict the impact of climate change on large assemblages of plant communities ...

平原造林工程影响下的河岸带土壤生态化学计量特征

open access: yesShuitu Baochi Xuebao, 2022
北京主要河流河岸带实施平原造林工程后,对河岸带植被类型及土壤造成不同程度影响。研究河岸带原有及重建植被类型土壤生态化学计量特征,对河岸生态系统土壤碳氮磷平衡及固碳潜力提升提供科学依据。选取北京温榆河昌平段岸边原有植被类型3种样地(乔木林、乔灌林及草地),重建植被类型2种样地(乔木林与灌木林),共15个样方,采集3层(0—10,10—20,20—30 cm)土壤样品,分析并计算碳(C)、氮(N)和磷(P)含量及计量比。结果表明:原有与重建植被类型的土壤有机碳(SOC)、全氮(TN)、全磷(TP ...

豫东北黄泛区易风蚀性土壤特征

open access: yesShuitu Baochi Xuebao, 2021
为分析不同土壤类型的性质、界定易风蚀性土壤类型并探索其特征,选取豫东北黄泛区为研究区域,采用野外取样、室内试验分析结合的方法测定土壤颗粒粒径、可蚀性因子K值等指标,界定区域易风蚀性土壤类型,并分析其空间分布特征。结果表明:(1)从土类看,豫东北黄泛区4种土类,以潮土为主,占区域面积的65.57%;从亚类看,共11种土壤亚类,以小两合土、沙土为主,占区域面积的59.76%。(2)土壤颗粒粒径组成上,沙土、草甸风沙土、盐化潮土、淤土等类型以砂粒为主;其余类型以粉粒为主。沙土、草甸风沙土、灌淤潮土 ...
