Studies of birds that use stable isotopes as dietary tracers require estimates of how quickly stable isotopes in tissues are replaced by isotopes derived from the diet. However, isotopic turnover rates in animals in general, and birds in particular, are poorly understood. We established the turnover rates of '3C in tissues of grown Japanese Quail (Coturnixjaponica) by switching the diet of an experimental group from a wheat-based (C3) diet to a corn-based (C4) diet and sampled tissues…

Assessing Avian Diets Using Stable Isotopes II: Factors Influencing Diet-Tissue Fractionation

It is suggested that nutritional stress caused substantial increases in diet-tissue fractionation values due either to: (1) mobilization and redeposition of proteins elsewhere in the body; or (2) amino acid composition changes in tissues.

Turnover of carbon isotopes in tail hair and breath CO2 of horses fed an isotopically varied diet

The hair and blood bicarbonate of two adult horses in this study are found to be successfully described by a model having three exponential isotope pools, and it seems that a greater proportion of the amino acids available for hair synthesis come from endogenous sources compared to the compounds undergoing cellular catabolism in the body.

Growth versus metabolic tissue replacement in mouse tissues determined by stable carbon and nitrogen isotope analysis

This study assessed the rate of carbon- and nitrogen-isotope turnover in liver, muscle, and blood in mice (Mus musculus L., 1758) following a diet change and reported the proportion of tissue turnover caused by growth versus that caused by metabolic tissue replacement.

Effects of elemental composition on the incorporation of dietary nitrogen and carbon isotopic signatures in an omnivorous songbird

Feathers were the most enriched and whole blood and plasma were the least enriched or, in the case of carbon, slightly depleted relative to diet, and for all tissues, carbon and nitrogen isotope discrimination factors increased withcarbon and nitrogen concentrations of diets.

Resolving temporal variation in vertebrate diets using naturally occurring stable isotopes

Three different approaches that have been used to resolve temporal diet variation through analysis of stable isotopes are reviewed and urged for more laboratory experiments aimed at improving the understanding of differential assimilation of dietary components, isotopic fractionation and metabolic routing.

Tissue-specific turnover rates of the nitrogen stable isotope as functions of time and growth in a cyprinid fish

Ecological applications of stable isotope data require knowledge on the isotopic turnover rate of tissues, usually described as the isotopic half-life in days (T0.5) or the change in mass (G0.5).

Stable carbon and nitrogen isotopic fractionation between diet and tissue of captive red fox: implications for dietary reconstruction.

This study is the first to report isotopic frac - tionation values for a terrestrial mammalian carnivore, necessary to interpret stable-isotope patterns in wild carnivores.

Effect of diet switch on turnover rates of tissue nitrogen stable isotopes in fish based on the enrichment-dilution approach

Turnover rate was estimated from the dilution of a N label introduced into consumer tissues by feeding of N鄄enriched cyanobacteria by demonstrating that growth accelerated the rate of isotopic change and caused tissue specific turnover rates.

Isotopic incorporation rates for shark tissues from a long-term captive feeding study

In spite of their large size and unusual physiology, the rates of isotopic incorporation in sharks seem to follow the same patterns found in other aquatic ectotherms.

Turnover of stable isotopes in Hokkaido brown bear (Ursus arctos yesoyensis)

The results of experiments estimating isotopic turnover rates as well as determining possible seasonal fluctuation in turnover rates of captive Hokkaido brown bears are reported.

STABLE ISOTOPES IN ECOSYSTEM STUDIES

The use of stable isotopes to solve biogeochemical problems in ecosystem analysis is increasing rapidly because stable isotope data can contribute both source-sink (tracer) and process information:

Use of stable-carbon isotope analysis to estimate marine and terrestrial protein content in gull diets

  • 1987
The narrow distribution of δ13C values for Western Gulls from the Southeast Farallon Island colony suggests that gull colonies may be calibrated so that changes in dependence on terrestrial protein can be monitored.

FIELD METABOLIC RATE AND FOOD REQUIREMENT SCALING IN MAMMALS AND BIRDS

Field metabolic rates (FMRs or HF), all measured using doubly labeled water, of 23 species of eutherian mammals, 13 species of marsupial mammals, and 25 species of birds were summarized and analyzed

Stable Carbon Isotopes in Terrestrial Ecosystem Research

It has been known for some time that terrestrial plants, the primary producers, possess δ13C values substantially lower (more negative, 13C-depleted) than that of ambient atmospheric CO2 (ca. -7.7%).

Dependence of the carbon-isotope contents of breath carbon dioxide, milk, serum and rumen fermentation products on the δ13C value of food in dairy cows

Six dairy cows of two breeds were fed during three alternating periods with products from C3- and C4- plants to yield different natural 13C enrichments of the diet, and an isotopic balance model for the breath CO2 could be established.

Stable isotope analysis of marbled murrelets : evidence for freshwater feeding and determination of trophic level

Stable carbon and nitrogen isotopic analyses of muscle tissue from Marbled Murrelets and nine other species of alcids from British Columbia and the high Arctic indicate that stablenitrogen isotope analysis is potentially useful for establishing trophic relationships in seabird communities.

Energy Requirements for Existence in Relation to Size of Bird

Existence energy requirements in cages, measured for 18 species weighing from 9 to 4300 g and belonging to three different orders, provide sufficient data to test variation with the size of the bird and to correlate existence metabolism with standard metabolism.

Importance of body tissues as sources of nutrients for milk synthesis in the cow, using 13C as a marker

The proportional contribution of body-tissue C to individual milk constituents varied considerably between animals, possibly associated with genetic merit or the size of the body reserves available for mobilization.
