Abstract Chemical analysis of calcified structures continues to flourish, as analytical and technological advances enable researchers tap into trace elements isotopes taken up in otoliths other archival tissues at ever greater resolution. Increasingly, these tracers are applied refine age estimation interpretation, chronicle responses environmental stressors, linking ecological, physiological, life-history processes. Here, we review emerging approaches innovative research directions otolith...
Abstract Age estimates from bomb 14 C dating conflict with a well-recognized age reading protocol (grinding, polishing and staining in the sagittal plane) for otoliths of European eel ( Anguilla anguilla ). Proper alignment calculated hatch years measurements taken earliest otolith growth—among smallest extractions to date successful analysis due advent gas-AMS—was not achieved using an accepted method. The realignment values tropical reference chronology, which is most applicable Sargasso...
Abstract Understanding the age structure and population dynamics of harvested species is crucial for sustainability, especially in fisheries. The Bigmouth Buffalo ( Ictiobus cyprinellus ) a fish endemic to Mississippi Hudson Bay drainages. A valued food-fish centuries, they are now prized sportfish as night bowfishing has become million-dollar industry past decade. All harvest virtually unregulated unstudied, declining while little known about their biology. Using thin-sectioned otoliths...
Studies of risk factors associated with reactions among autologous blood donors have been limited. Therefore, 2091 and 4737 homologous donations were examined. Donors at greatest for reaction who had first donation; 45 made repeat the same surgery, 17 (38%) reactions. The group least likely to experience ≥66 years old; they experienced a 1.9≥ percent (6/310) incidence More seen in both categories first‐time donor, female gender, decreasing age, lower weight. Multiple logistic regression...

Life-span estimates for orange roughy ( Hoplostethus atlanticus ) range from ~20 years to well over 100 years. In this study, an improved lead–radium dating technique provided independent age sagittal otoliths. This used the known properties of radioactivity lead-210 and radium-226 determine validity fish estimates. An improvement using mass spectrometry allowed use smaller samples than previously possible; therefore, application was made otolith cores, first few growth. approach...
Demersal reef fishes of the Indo-Pacific are under increasing pressure as a fisheries resource, yet many important life history characteristics required for suitable management poorly known. The three fish species, eightbar grouper (Hyporthodus octofasciatus), ruby snapper (Etelis carbunculus) and spangled emperor (Lethrinus nebulosus), components ecosystems throughout Indo-Pacific. Despite their importance, age growth information is incomplete. Age has been estimated E. carbunculus L....
Growth characteristics of Pristipomoides filamentosus, a deepwater eteline snapper major economic importance, are incomplete and inconsistent across its geographical range. Early growth rates have been validated using daily increment length–frequency analyses, but historical estimates adult variable longevity is unknown. Studies P. filamentosus in the Hawaiian Islands cautioned against unjustified longevity, 18 years has at times uncritically assumed as maximum age. The present study...
Abstract Cardinal snapper Pristipomoides macrophthalmus is a commercially important, but commonly misidentified, deepwater species in artisanal and semi-industrial fisheries throughout the Caribbean Sea. As with many tropical fishes, little known about biology or ecology of species. Bomb radiocarbon ( 14 C) dating was applied to cardinal sagittal otoliths collected from waters Belize Honduras during 2015–2019 investigate lifespan thin-sectioned an evaluation otolith mass as proxy for age....
A multidisciplinary approach incorporating otolith chemistry, age data, and numerical Lagrangian particle simulations indicated a single, self-recruiting population of Antarctic toothfish (Dissostichus mawsoni) in the Southeast Pacific Basin (SPB) Ross Sea, with life history structured by large-scale circulation. Chemistry deposited prior to capture along edges demonstrated strong environmental heterogeneity, yet chemistry nuclei, during early life, showed no differences. Age data only adult...
Growth characteristics are poorly understood for speckled hind (Epinephelus drummondhayi), a tropical deep-water grouper of economic importance that is considered overfished. Age has been validated early growth, but the validity adult age estimates unknown. A few studies growth zones in otoliths have revealed maximum 15–35 years, which uncritically assumed as longevity. To answer questions about age, bomb radiocarbon dating was used to provide estimates. novel aspect this study use postbomb...

Abstract Corals of the Hawaiian Archipelago are well situated in North Pacific Gyre (NPG) to record how bomb-produced radiocarbon has been sequestered and transported by sea. While this signal can be traced accurately through time reef-building corals used infer oceanographic processes determine ages marine organisms, a comprehensive validated lacking for Archipelago.

Bomb radiocarbon analysis of vertebral growth bands was used to validate lifespan for sand tiger sharks (Carcharias taurus) from the western North Atlantic (WNA) and southwestern Indian Oceans (SIO). Visual counts were assign age estimate year formation (YOF) sampled in eight WNA two SIO. Carbon-14 results plotted relative YOF comparison with regional Δ14C reference chronologies assess accuracy estimates. Results validated estimates up 12 years, but indicated that ages large adult...
Abstract High‐resolution radiocarbon ( 14 C) analyses on a coral core extracted from Guam, western tropical Pacific island, revealed series of early bomb‐produced C spikes. The typical marine bomb signal—phase lagged and attenuated relative to atmospheric records—is present in the is consistent with other regional records. However, levels well above what can be attributed air‐sea diffusion alone punctuate this pattern. This anomaly was observed Indo‐Pacific records, but Guam record unmatched...
Current and historic longevity estimates for the Pacific grenadier (Coryphaenoides acrolepis) range from 6 to greater than 60 years. Age in this study using growth increment counts thin otolith sections indicate is a long-lived fish. To validate information, age was determined radioactive disequilibria of 210 Pb 226 Ra cores adult grenadier. Radiometric ages closely agreed with counting increments, which confirms their annual periodicity. results can live at least 55.8 years (-7.4, +10.1...
In the year of 2017, capital expenditure Flash-based Solid State Drivers (SSDs) keeps declining and storage capacity SSDs increasing. As a result, "selling point" traditional spinning Hard Disk Drives (HDDs) as backend - low cost large is no longer unique, eventually they will be replaced by low-end which have but perform orders magnitude better than HDDs. Thus, it widely believed that all-flash multi-tier systems adopted in enterprise datacenters near future. However, existing caching or...
Little is known about long-term changes in coral reef fish communities. Here we present a new technique that leverages otoliths sediments to reconstruct We found over 5,400 169 modern and mid-Holocene bulk samples from Caribbean Panama Dominican Republic reefs, demonstrating are abundant sediments. With specially-built reference collection, were able assign 4,400 one of 56 taxa (35 families) though mostly at genus family level. Many juvenile fishes for which identification challenging....
