Methodological constraints for the stable isotope analysis of different tissues: A comparison between muscle and whole‐body samples in freshwater gammarids

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Carbon (δ13C) and nitrogen (δ15N) stable isotope ratios allow the reconstruction of food webs, provided that all trophic levels are properly characterized. In freshwater ecosystems, small‐bodied invertebrates often occupy central positions in food webs, with whole‐body samples commonly used for their stable isotope analysis, due to ...

Pulse Programme Considerations for Quantitative NOE Analysis

open access: yesMagnetic Resonance in Chemistry, EarlyView.
NOESY and ROESY spectra are frequently used to obtain interatomic distances in solution. Here, the performance of six routinely used pulse programmes is evaluated, with the number of quantified correlations and the accuracy of the NOE‐based distances being used as the main assessment criteria. ABSTRACT Accurate NOE/ROE‐based distance determination is a

Unshared on the top: strong segregation of pathogen communities between western honey bees and wild bees in a retreating glacier foreland

open access: yesOikos, EarlyView.
Shared flowers can facilitate pathogen transmission between managed honey bees and wild bees, yet this process remains poorly understood in ecosystems undergoing rapid environmental change. Using a glacier foreland in Switzerland, we present the first study on how glacier retreat stages and bee life‐history traits influence pathogen occurrence across ...
