Using ocean models to predict spatial and temporal variation in marine carbon isotopes

Ecosphere, Journal Year: 2017, Volume and Issue: 8(5)

Published: May 1, 2017

Abstract Natural‐abundance stable isotope ratios provide a wealth of ecological information relating to food web structure, trophic level, and location. The correct interpretation data requires an understanding spatial temporal variation in the isotopic compositions at base web. In marine pelagic environments, accurate is hampered by lack reliable, spatio‐temporally distributed measurements baseline compositions. this study, we present relatively simple, process‐based carbon model that predicts spatio‐temporal distributions composition phytoplankton (here expressed as δ 13 C PLK ) across global ocean one degree monthly resolution. driven output from coupled physics‐biogeochemistry model, NEMO ‐ MEDUSA , operates offline; it could also be alternative underlying systems.

A review of niche segregation across sympatric breeding seabird assemblages

Ibis, Journal Year: 2024, Volume and Issue: unknown

Published: Feb. 1, 2024

Breeding seabirds challenge the concept of niche segregation among competing species because similar competitors with comparable life histories can coexist in large multi‐species colonies. This makes them an ideal model organism for studying Hutchisonian model, which proposes interspecific segregation, across n ‐dimensions. Recent advances assessment ecological niches have improved our understanding mechanisms leading to at‐sea segregation. We examine 152 published studies investigating one or more three spaces breeding seabirds: dietary items, stable isotopes (isotopic niche) and spatial distribution (horizontal vertical). Most focused on rather then multiple combination. When were combined, higher than overlap was reported, compared when assessed individually, as is predicted by ‐dimensional hypervolume concept. Studies vertical (diving) foraging dimensions addition traditional horizontal (spatial) reported overlap, focusing only dimensions. Segregation increased colony size, suggesting effect competition. also during chick‐rearing, taxa phylogenetically distant, ecology similar. To gain a comprehensive sympatric competitors' interactions their space, it important combine approaches standardize methodologies. Embracing multidimensional assess seabird inform effective conservation management practices marine ecosystems.

Foraging and recruitment hotspot dynamics for the largest Atlantic loggerhead turtle rookery

Determining patterns of migratory connectivity for highly-mobile, wide-ranging species, such as sea turtles, is challenging. Here, we combined satellite telemetry and stable isotope analysis to estimate foraging locations 749 individual loggerheads nesting along the east central Florida (USA) coast, largest rookery Northwest Atlantic population. We aggregated results by year, identified seven hotspots tracked these summaries describe dynamics inter-annual contributions geographic areas this over a nine-year period. Using reproductive information subset turtles (n = 513), estimated hatchling yields associated with each hotspots. found considerable variability in relative contribution adults. Also success differed among hotspots; females using southern laid nests that produced more offspring all but one year study. These analyses two high priority future research conservation efforts: continental shelf adjacent Great Bahama Bank, which support higher numbers provide rates production.

Abstract Spatial models of variation in the isotopic composition structural nutrients across habitats (isoscapes) offer information on physical, biogeochemical and anthropogenic processes occurring space, provide a tool for retrospective assignment animals or animal products to their foraging area geographic origin. The differences among reference samples used construct isoscapes may vary spatially according non‐spatial terms (e.g. sampling date, individual species effects). Partitioning variance between dependent independent is critical but overlooked aspect isoscape creation with important consequences design studies collecting data accuracy precision models.
