Otoliths, increments, and elements: keys to a comprehensive understanding of fish populations?

摘要: The chronological properties of otoliths are unparalleled in the animal world, allowing accurate estimates age and growth at both daily yearly scale. Based on successes calcified structures as environmental proxies other taxa, it was logical that researchers should attempt to link otolith biochronologies with chemistry. With benefit hindsight, this anticipation may have been naive. For instance, concentrations many elements lower than corals, bivalves, seal teeth, or bony fish, making them less ideal for elemental analyses. Nevertheless, there is growing interest use chemistry a natural tag fish stocks. Such applications directed questions concerning populations rather using passive recorder ambient environment do not rely upon any explicit relationship between variables can be addressed w...
