Biological transfer of nutrients and materials between linked ecosystems influences global carbon budgets ecosystem structure function. Identifying the organisms or functional groups that are responsible for nutrient transfer, quantifying their influence on capture is an essential step informed management in physically distant, but ecologically areas. Here, we combine natural abundance stable isotope tracers survey data to show mid-water bentho-pelagic-feeding demersal fishes play important...
Abstract Knowledge of the trophic structure and variability planktonic communities is a key factor in understanding food-web dynamics energy transfer from zooplankton to higher levels. In this study, we investigated how stable isotopes mesozooplankton species varied seasonally (winter, spring, autumn) relation environmental factors plankton size classes temperate coastal ecosystem. Our results showed that spring characterized by strongest vertical size-structured food-web, mainly fueled...
Knowing the distribution of marine animals is central to understanding climatic and other environmental influences on population ecology. This information has proven difficult gain through capture-based methods biased by capture location. Here we show that location can be inferred from animal tissues. As carbon isotope composition tissues varies with sea surface temperature, identified matching time series isotopes measured in temperature records. Applying this technique populations Atlantic...
The Arctic is warming rapidly, with concomitant sea ice losses and ecosystem changes. animals most vulnerable to food web changes are long-lived slow-growing such as marine mammals, which may not be able adapt rapidly enough respond in their resource bases. To determine the current extent sources of these bases, we examined isotopic trophic niches for mammals European using skin carbon (δ13C) nitrogen (δ 15N) stable isotope (SI) compositions from 10 species: blue, fin, humpback, minke, sperm...
Global warming is causing rapid change in marine food webs, particularly at northern latitudes where temperatures are increasing most rapidly. In this study, the diet of common minke whales Balaenoptera acutorostrata was assessed both terms short-term (morphological analyses digestive tract contents) and longer-term (tissue chemical markers: fatty acids stable isotopes) prey use Barents Sea to see if they shifting. Samples (blubber cores, muscle, stomach were obtained from 158 taken during...
Summary Retrospective determination of location for marine animals would facilitate investigations migration, connectivity and food provenance. Predictable spatial variations in carbon nitrogen isotopes primary production across shelf seas provide a basis stable isotope‐based location. Here, we assess the accuracy precision that can be obtained through dietary‐isotope‐based methods. We build isoscapes from jellyfish tissues use these to assign scallops fixed known individual location,...
Incrementally grown, metabolically inert tissues such as fish otoliths provide biochemical records that can used to infer behavior and physiology throughout the lifetime of individual. Organic are particularly useful stable isotope composition organic component information about diet, trophic level location. Unfortunately, inert, incrementally grown relatively uncommon. The vertebrate eye lens, however, is formed via sequential deposition protein-filled fiber cells, which subsequently inert....
Abstract MacKenzie, K. M., Trueman, C. N., Palmer, M. R., Moore, A., Ibbotson, A. T., Beaumont, W. R. C., and Davidson, I. 2012. Stable isotopes reveal age-dependent trophic level spatial segregation during adult marine feeding in populations of salmon from the UK. – ICES Journal Marine Science, 69: 1637–1645. Locating differentiating areas used by (Salmo salar) is essential to stock-based management conservation, but traditional tagging studies are limited influenced uneven distribution...
The outcome of 75 consecutive bilateral breast reduction procedures on 73 patients (65 inferior pedicle and 9 superior with inverted-T closure, 1 ultrasonic-assisted lipoplasty) is evaluated. Fifty-six surveys at an average follow-up 35 months, 36 standardized examinations 31 52 paired preoperative/postoperative photographs, chart reviews comprise the data. Mean age surgery was 32 years. Of surveyed, there were 51 whites, 18 blacks, 4 other races. majority survey respondents reported...
Abstract Trueman, C. N., MacKenzie, K. M., and Palmer, M. R. 2012. Stable isotopes reveal linkages between ocean climate, plankton community dynamics, survival of two populations Atlantic salmon (Salmo salar). – ICES Journal Marine Science, 69: 784–794. An 18-year record stable from salar) migrating to different regions the North reveals climate-driven subdecadal variations. Time-series carbon in one stock, thought feed Faroes/Iceland Basin area, show Subpolar Gyre (SPG) modal variability,...
The otolith, found in both inner ears of bony fish, has mainly been used to estimate fish age. Another application that developing significantly recent years, however, is the use otolith shape as a tool for stock identification. Often, studies have directly asymmetry between right and left otoliths. We tested magnitude directional sagittal otoliths (left vs. right) 2991 individuals according their catch locations, we selected species evaluate whether may itself be boundaries. Elliptical...
Among all human-induced pressures, ocean warming is expected to be one of the major drivers change in marine ecosystems. Fish species are particularly vulnerable during embryogenesis. Here, impact temperature was assessed on embryonic stages Atlantic herring (Clupea harengus), a high socio-economic interest, with particular focus under-studied eastern English Channel winter-spawning component (Downs herring). Key traits linked growth and development were experimentally evaluated at three...
Although otoliths are widely used as archives to infer life-history traits and habitat use in fishes, their biomineralization process remains poorly understood. This lack of knowledge is problematic it can lead misinterpretation the different types signals (e.g., optical or chemical) that provide basic data for research fish ecology, fisheries management, species conservation. Otolith calcification relies on a complex system involving pericrystalline fluid, endolymph, whose organic inorganic...
In September 2016, a marine ecosystem survey covered all trophic levels from phytoplankton to seals in the Arctic Ocean west and north of Svalbard. At ice edge, 26 harp were sampled assess whether recent environmental changes had affected their diets body condition by comparing our current results with previous investigations conducted 2–3 decades ago northern Barents Sea, when edge was located much further south. Our suggest that slightly but significantly lower for one year older 2016...
The intercalibration of age readings represents a crucial step in the ageing procedure; use different sampling methods, structures, preparation techniques, and criteria can significantly affect growth data. This study evaluated precision accuracy for most important North Atlantic (NA) Mediterranean (M) ray species,
