Data from: Assessing stable isotope dynamics of diapausing Calanus finmarchicus and C. hyperboreus during the overwintering period: a laboratory experiment
- 负责人：
- DOI：
- doi:10.5061/dryad.vb5pj
- 摘要：
- and ?15N signatures as well as lipid, carbon and nitrogen content. Lipids were extracted in half of the samples to compare ?13C of individuals
Data from: Detrital subsidy from subtidal kelp beds is altered by the invasive green alga Codium fragile ssp. fragile
- 负责人：
- DOI：
- doi:10.5061/dryad.4b2t6
- 摘要：
- , a secondary metabolite that deters grazers), and isotopic composition (δ13C and δ15N) between C. fragile and the native kelp Saccharina latissima at 4 wk intervals over 16
Data from: Two widespread green Neottia species (Orchidaceae) show mycorrhizal preference for Sebacinales in various habitats and ontogenetic stages
- 负责人：
- DOI：
- doi:10.5061/dryad.033ds
- 摘要：
- to ectomycorrhizal fungi and a high natural 13C and 15N abundance. Some green relatives of mycoheterotrophic species show identical trends, but most of these remain
Data from: Partitioning between atmospheric deposition and canopy microbial nitrification into throughfall nitrate fluxes in a Mediterranean forest
- 负责人：
- DOI：
- doi:10.5061/dryad.3cq6127
- 摘要：
- . We quantified NH4+—N and NO3-—N fluxes for rainfall (RF) and throughfall (TF) and used ?15N, ?18O, and ?17O to elucidate sources of NO3-. Finally
Data from: Watershed versus within-lake drivers of nitrogen: phosphorus dynamics in shallow lakes

- DOI：
- doi:10.5061/dryad.6b650
- 摘要：
- s in sediment cores from a subset of 34 lakes, and by measuring seston δ15N in four additional experimental lakes before and after they were experimentally manipulated
Data from: Isotopic niche reflects stress-induced variability in physiological status
