- 摘要：
- Lipid extraction of biomass prior to stable isotope analysis is known to cause variable changes in the stable nitrogen isotopic composition (d15N
Data from: Fate of atmospherically deposited NH4+ and NO3- in two temperate forests in China: temporal pattern and redistribution

- 摘要：
- of different forms of deposited N as well as the redistribution over time within different ecosystems is limited. In this study we used the 15N-tracer method

- 摘要：
- of the possible variation in disturbance type and intensity across chronosequence sites. We hypothesized that tree ring ?15N, as a record of ecosystem N status
Data from: Midwater zooplankton and suspended particle dynamics in the North Pacific Subtropical Gyre: a stable isotope perspective
- 负责人：
- DOI：

- , carbon sequestration, nutrient fluxes to aquatic systems, and climate forcing. With limited direct measures of soil N cycling at the global scale, syntheses of the 15N
Data from: Isotopic evidence for oligotrophication of terrestrial ecosystems
- 负责人：
- DOI：
- doi:10.5061/dryad.v2k2607
- 摘要：
- nitrogen (N) availability is uncertain. Examining patterns of foliar N concentrations ([N]) and isotope ratios (?15N) from more than 42,000 samples acquired ove
Data from: Validating the incorporation of 13C and 15N in a shorebird that consumes an isotopically distinct chemosymbiotic bivalve

- 摘要：
- in chemosynthesis-based ecosystems. In this paper we present such a validation experiment for the incorporation of 13C and 15N in the blood plasma of a medium-sized
Data from: The diverse dietary profiles of MIS 3 cave bears from the Romanian Carpathians: insights from stable isotope (δ13C and δ15N) analysis
- 负责人：

- 摘要：
- Late Pleistocene European cave bears (Ursus spelaeus) have been considered to be largely vegetarian, although stable isotope data (δ13C and δ15N
