Natural isotopic composition of carbon (d13C) correlates with colony size in the planktonic cyanobacterium Gloeotrichia echinulata
Natural isotopic composition of carbon d13C correlates with colony size planktonic cyanobacterium Gloeotrichia echinulata
2014/4/18
To assess variability in carbon isotope signatures (δ13C) between and within populations under natural conditions, with a particular emphasis on colony size, we repeatedly collected planktonic colonie...
Tracing terrestrial organic matter by d34S and d13C signatures in a subarctic estuary
Tracing terrestrial organic matter d34S and d13C signatures a subarctic estuary
2014/4/21
A key issue to understanding the transformations of terrestrial organic carbon in the ocean is to disentangle the latter from marine-produced organic matter. We applied a multiple stable isotope appro...
Patterns in the d13C and d15N signature of Ulva pertusa: Interaction between physical gradients and nutrient source pools
Patterns in the d13C and d15N signature of Ulva pertusa Interaction between physical gradients nutrient source pools
2014/4/23
Field surveys and laboratory experiments were used to investigate the influence of the physical environment on variability in δ13C and δ15N signatures of Ulva pertusa, an abundant macroalgae inhabitin...
Temporal and spatial variation in the d15N and d13C of coral tissue and zooxanthellae in Montastraea faveolata collected from the Florida reef tract
Temporal and spatial variation d15N and d13C coral tissue and zooxanthellae Montastraea faveolata collected Florida reef tract
2014/5/9
Tissues were collected from Montastraea faveolata at five locations on the Florida Reef tract representing both nearshore and offshore environments. The tissue and zooxanthellae were removed from the ...
Interspecific and intraspecific variation of d13C and d15N in deposit- and suspension-feeding bivalves (Macoma balthica and Cerastoderma edule): Evidence of ontogenetic changes in feeding mode of Macoma balthica
Interspecific and intraspecific variation d13C and d15N deposit- and suspension-feeding bivalves ontogenetic changes feeding mode Macoma balthica
2014/5/14
Deposit and suspension feeders can switch feeding behavior and show variations in feeding mode as individuals pass through life-cycle stages. Stable carbon and nitrogen isotopes were used to trace cha...
d13C of fluvial mollusk shells (Rhone River): A proxy for dissolved inorganic carbon?
d13C fluvial mollusk shells dissolved inorganic carbon
2014/5/22
The relationship between the δ13C of dissolved inorganic carbon (DIC) and modern mollusk aragonite from rivers was calibrated for the purpose of reconstructing DIC paleochemistry from the shell record...

Carbon sources demersal fish the western Seto Inland Sea Japan examined by d13C d15N analyses
2014/5/27
The relative importance of benthic and pelagic primary production for demersal fish and some invertebrates in the western Seto Inland Sea of Japan was examined using carbon and nitrogen stable isotope...
