Tracking Animal Migration with Stable Isotopes. Edited by. K.A. Hobson, Environment Canada, Saskatoon, Saskatchewan, Canada; L.I. Wassenaar, Environment ... Animal Migration: A Context for Using New Techniques and Approaches 2.

This book provides a consolidated overview of the current knowledge of stable isotopes in terrestrial migration research questions. Robust descriptions of isotopic patterns across space and time, called "isoscapes," form the basis of a rapidly growing and wide-ranging body of research aimed at quantifying connectivity within and among Earth's systems. Movement patterns and annual migrations of animals are vital components of their ecology but have generally been poorly studied due to fundamental limitations in using exogenous markers.

This work illustrates the analytical power of dendritic network models for the field of isotope biogeochemistry, particularly for provenance studies of modern and ancient animals. The uptake kinetics between environmental calcium and its competing mimics define what is ultimately incorporated in the biomineral structure. The effects of mathematical lipid correction on δ13C turnover and discrimination were examined by developing novel empirical equations involving C:N ratios and lipid δ13C values.

Tissue-specific isotope turnover and discrimination factors are affected by diet quality and lipid content in an omnivorous consumer "Accurate interpretations of diet histories from tissue-specific stable isotope ratios require a detailed understanding of the factors that affect 1) the time frame represented by the tissue analyzed (i. Environmental temperature and pH as well as uptake kinetics for strontium and barium isotopes demonstrate the role of mass fractionation in isotope selection for uptake into fish bony structures. Assessing dispersal in threatened migratory birds using stable hydrogen isotope (δD) analysis of fea. It offers ecologists and conservation biologists provide a practical handbook for those considering using stable isotopes in their migration research.

    Tracking Animal Migration with Stable Isotopes,2, K. A. Hobson

    The uptake kinetics between environmental calcium and its competing mimics define what is ultimately incorporated in the biomineral structure. Improvements in our understanding of the factors causing annual deviations from isoscape patterns based on long-term datasets are needed to improve resolution of placing animals to origins. Stable isotope measurements of animal tissues represent endogenous markers that can provide information on origins because they reflect isoscape patterns occurring at various scales.

    A critical challenge for the Earth sciences is to trace the transport and flux of matter within and among aquatic, terrestrial, and atmospheric systems. Otoliths are the last place of deposition for calcium and are considered a calcium sink (Ichii and Mugiya, 1983; Shinozaki and Mugiya, 2000 ) thus the observed otolith 86 Sr/ 87 Sr ratios are thought to be a direct relationship to naturally occurring environmental ratios (Barnett-Johnson et al. Biomineral chemistry is frequently used to infer life history events and habitat use in fishes; however, significant gaps remain in our understanding of the underlying mechanisms.

    Here we demonstrate how dendritic network models substantially improve the accuracy of isoscapes of strontium isotopes and partition the influence of hydrologic transport versus local geologic features on strontium isotope ratios in a large Alaska river. In cases where animals move among isotopically distinct regions or over isotopic gradients, the isotopic measurement of a tissue representing the appropriate period of dietary integration can be used to place animals spatially and temporally. Dendritic network models: Improving isoscapes and quantifying influence of landscape and in-stream processes on strontium isotopes in rivers "Isotopic tracers are used widely to quantify spatial and temporal patterns in the transport and flux of matter across Earth's surface [Bowen, 2010]. Robust descriptions of isotopic patterns across space and time, called "isoscapes," form the basis of a rapidly growing and wide-ranging body of research aimed at quantifying connectivity within and among Earth's systems.
