Carbon stable isotopes as a palaeoclimate proxy in vascular plant dominated peatlands
Carbon stable isotope (dC) records from vascular plant dominated peatlands have been used as a palaeoclimate proxy, but a better empirical understanding of fractionation processes in these ecosystems is required. Here, we test the potential of dC analysis of ombrotrophic restiad peatlands in New Zealand, dominated by the wire rush (Empodisma spp.), to provide a methodology for developing palaeo...
متن کاملMesoscale patterns of altitudinal tenancy in migratory wood warblers inferred from stable carbon isotopes.
We analyzed carbon isotope ratios (delta13C) of liver and pectoral muscle of Black-throated Blue Warblers (Dendroica caerulescens) to provide a mesoscale perspective on altitudinal tenancy in the Appalachian Mountains, North Carolina, U.S.A. Movements of males are poorly understood, particularly the degree to which yearlings (first breeding season) and older males (second or later breeding seas...

متن کاملCarbon stable isotopes as indicators of coastal eutrophication.
Coastal ecologists and managers have frequently used nitrogen stable isotopes (delta15N) to trace and monitor sources of anthropogenic nitrogen (N) in coastal ecosystems. However, the interpretation of delta15N data can often be challenging, as the isotope values fractionate substantially due to preferential retention and uptake by biota. There is a growing body of evidence that carbon isotopes...
متن کاملAllocation to Reproduction in a Hawkmoth: a Quantitative Analysis Using Stable Carbon Isotopes
There is great interest in the importance of nectar nutrients to fecundity in the Lepidoptera, but nutrient allocation has been difficult to measure quantitatively. Here we trace the allocation of nectar nutrients in the hawkmoth Amphion floridensis using naturally occurring variation in plant stable carbon isotopes and thereby derive a descriptive model of carbon flow into eggs. Because 13C co...
