SWAMP: A new experiment for simulating permafrost warming and active layer deepening on the Tibetan Plateau

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.

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

Methods 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 ...

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 ...
