Isotopologue Ratios Identify 13C‐Depleted Biomarkers in Environmental Samples Impacted by Methane Turnover

open access: yesRapid Communications in Mass Spectrometry, Volume 39, Issue 22, 30 November 2025.
ABSTRACT Rationale The stable carbon isotopic composition (δ13C) of individual lipids is of great value in studying carbon cycling. Among those, microbial lipids in sediments impacted by high methane turnover stand out due to their uniquely depleted isotopic fingerprint.

Resolving taxa in a challenging orchid species complex using evidence from phylogenetics, morphometrics and floral scent chemistry

open access: yesTAXON, Volume 74, Issue 4, Page 787-804, August 2025.
Abstract Species can be difficult to circumscribe using morphology alone, and additional data can thus be useful for resolving challenging species complexes. Here we provide a case study of a South African orchid species complex which we resolved by analysing morphology, floral scent chemistry and molecular data.
