DOI: 10.1002/ajb2.1183
Abstract: PREMISE OF THE STUDY The Hymenochaetales are dominated by lignicolous saprotrophic fungi involved in wood decay. However, the group also includes bryophilous and terricolous taxa, but their modes of nutrition are not clear. Here, we… read more here.

DOI: 10.1002/ece3.9221
Abstract: Abstract Fish have one of the highest occurrences of individual specialization in trophic strategies among Eukaryotes. Yet, few studies characterize this variation during trophic niche analysis, limiting our understanding of aquatic food web dynamics. Stable… read more here.

DOI: 10.1002/ece3.9709
Abstract: Abstract Stable isotope mixing models (SIMMs) are widely used for characterizing wild animal diets. Such models rely upon using accurate trophic discrimination factors (TDFs) to account for the digestion, incorporation, and assimilation of food. Existing… read more here.

DOI: 10.1002/pmic.202000007
Abstract: Targeted proteomics depends on the availability of stable isotope labeled (SIL) peptide standards, which for absolute protein quantification need to be absolutely quantified. In the present study, three new approaches for absolute quantification of SIL… read more here.
