Defoliation and fertilisation differentially moderate root trait effects on soil abiotic and biotic properties

open access: yesJournal of Ecology, Volume 111, Issue 12, Page 2733-2749, December 2023., 2023
Our results indicate that defoliation and fertilisation, two common grassland perturbations, have contrasting impacts on root traits of grassland plant species, with direct and indirect short‐term consequences for a wide range of soil abiotic and biotic properties that underpin ecosystem functioning.

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 ...
