Mollusk shells contain many isotopic clues about calcification physiology and environmental
conditions at the time of shell formation. In this review, we use both published and …

Metabolic costs are central to individual energy budgets, making estimates of metabolic rate
vital to understanding how an organism interacts with its environment as well as the role of …

Naturally occurring variations in the stable isotope composition of fossil vertebrates have
been studied since the late 1970s. Isotopic data from vertebrate fossils are sometimes used …

Paleothermometry is an essential tool for understanding past changes in climate. The
'carbonate clumped isotope thermometer'is a temperature proxy related to ordering of 13C …

Fish otoliths' chronometric properties make them useful for age and growth rate estimation in
fisheries management. For the Eastern Baltic Sea cod stock (Gadus morhua), unclear …

Otolith stable carbon isotope ratios provide a unique and widely applicable environmental
record. Unfortunately, uncertainty regarding the proportion of otolith carbon that derives from …

Knowledge of metabolic costs associated with maintenance, foraging, activity and growth
under natural conditions is important for understanding fish behaviours and the bioenergetic …

Stable isotope analyses (SIA) of carbon and nitrogen are used routinely in food-web studies
to determine diet and trophic position. We tested several common assumptions of SIA by …

Otoliths are small structures found in the inner ear of teleost fish that act as organs of
equilibrium and as direction and sound detectors. They possess unique characteristics that …

Conventional tags applied to individuals have been used to investigate animal movement,
but these methods require tagged individuals be recaptured. Maps of regional isotopic …
