Functional 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 ...

Methods in Ecology and Evolution, Volume 14, Issue 7, Page 1732-1746, July 2023., 2023 Abstract Our knowledge on the responses of permafrost ecosystems to climate warming is critical for assessing the direction and magnitude of permafrost carbon‐climate feedback. However, most of the previous experiments have only been able to warm the air and surface soil, with limited effects on the permafrost temperature.

Factors that shape large‐scale gradients in clonality
Journal of Biogeography, Volume 50, Issue 5, Page 827-837, May 2023., 2023 Abstract Aim Many plant species reproduce clonally. However, ecologists still have much to learn about the factors that shape large‐scale patterns in plant clonal growth and reproduction, especially in the southern hemisphere. We addressed this knowledge gap by quantifying relationships between reproductive mode and a suite of plant characteristics and

A novel red‐edge spectral index for retrieving the leaf chlorophyll content
Methods in Ecology and Evolution, Volume 13, Issue 12, Page 2771-2787, December 2022., 2022 Abstract The leaf chlorophyll content (Chlleaf) is a crucial vegetation parameter in carbon cycle modelling and agricultural monitoring at local, regional and global scales. The red‐edge spectral region is sensitive to variations in Chlleaf. An increasing number of sensors are capable of sampling red‐edge bands, providing opportunities to estimate ...

Shuitu Baochi Xuebao, 2022 淤地坝作为黄土高原重要的碳储库，其深层土壤有机碳稳定性在很大程度上影响坝地土壤储碳能力和碳排放。以黄土丘陵区不同利用年限的坝地为对象，从坝地剖面土壤有机碳含量及其组分入手，研究不同利用年限、不同沉积深度下，土壤有机碳含量及其稳定性的变化特征和影响因素。结果表明：（1）坝地深层土壤有机碳（SOC）含量低于该区坡耕地表层土壤有机碳含量，并未呈现明显的有机碳富集现象。随利用年限增加，坝地SOC含量呈增加趋势。（2）不同利用年限坝地的SOC、易氧化碳（EOC）、微生物量碳（MBC）、水溶性碳（DOC ...

Shuitu Baochi Xuebao, 2005 采用第二次土壤普查资料,研究了安徽省不同土地类型表层土壤的有机碳密度和碳库的特点。结果表明,安徽省平均有机碳密度为(31.64±16.39)tC/hm2,林地土壤表层有机碳密度高于全省表层土壤平均有机碳密度,旱作土壤表层有机碳密度则低于全省平均值。有机碳密度的大小顺序为:林地>水稻土耕层>旱地。安徽省表层土壤有机碳储量分布也表现为:林地>水稻土>旱地。表层土壤有机碳总量达0.28 Pg,其中林地占50%,水稻土占23%,而旱地只占18%。因此,人为利用特点是区域土壤碳库和碳密度的主要影响因素。分析表明 ...
