Embracing variability in amino acid δ15N fractionation: mechanisms, implications, and applications for trophic ecology
Compound‐specific stable isotope analysis (CSIA) of individual amino acids (AA s) has
become a powerful analytical tool in trophic ecology. Heavily fractionating “trophic” AA s (eg …

Global patterns of foliar nitrogen isotopes and their relationships with climate, mycorrhizal fungi, foliar nutrient concentrations, and nitrogen availability
Ratios of nitrogen (N) isotopes in leaves could elucidate underlying patterns of N cycling
across ecological gradients. To better understand global‐scale patterns of N cycling, we …

Nitrogen isotopes link mycorrhizal fungi and plants to nitrogen dynamics
In this review, we synthesize field and culture studies of the 15N/14N (expressed as δ15 N)
of autotrophic plants, mycoheterotrophic plants, parasitic plants, soil, and mycorrhizal fungi …
