WebOct 3, 2014 · We evaluated eye lenses as potential recorders of stable isotope histories in fish because they consist of metabolically inert optical proteins that are deposited in successive, concentric circles (laminae) much like otolith circuli and tree rings. We conducted four different tests on lenses from red snapper, red grouper, gag, and white … WebFish samples were washed with distilled water, dried, and homogenized before analysis. All samples were dried at 508C and stored wrapped in aluminum foil. Samples were analyzed at the University of Waterloo En-vironmental Isotope Lab on an isochrom continuous flow stable isotope mass spectrometer (Micromass) coupled to a
Using stable isotope data to advance marine food web modelling
WebFeb 7, 2013 · Introduction. The use of stable hydrogen (δ 2 H) and oxygen (δ 18 O) isotope measurements is well established in terrestrial ecological research to examine large … WebDec 14, 2024 · To estimate the impact of weirs on large river fish communities, we applied the ecological niche space (ENS) measured quantitatively using carbon and nitrogen stable isotope ratios to the monitoring of effects of weirs constructed on four major rivers in Korea. ENS was calculated using the Bayesian stable isotope in R statistics. The ENS of fish … nier replicant crack viet hoa

WebThis report gives an overview of spatial variation in carbon (δ13C ) and nitrogen (δ15N) stable isotopes in different fish species in the Baltic Sea. The study also tries to investigate if differences in contaminants between sites and among species can be partly explained by nitrogen stable isotopes. Moreover, as a WebJan 3, 2011 · For example, Oliveira et al. (2011) used stable isotope abundance in skeletal tissue to identify different gadoid fish species. Additionally, stable isotopes of d 18 O and d 13 C in fish bones ... WebThe values of natural abundance of stable isotopes were measured in 13 micronekton fish species sampled during the BATHYPELAGIC cruise (North Atlantic, June 2024). This dataset contains the values obtained for carbon and nitrogen in bulk tissues, and nitrogen values in amino acids. nier replicant difficulty differences
