Tracking long-distance migration of marine fishes using compound-specific stable isotope analysis of amino acids
The long-distance migrations by marine fishes are difficult to track by field observation. Here, we propose a new method to track such migrations using stable nitrogen isotopic composition at the base of the food web (<i>δ</i><sup>15</sup>N<sub>Base</sub>), which allows for direct comparison of isotope ratios between proxy organisms of the isoscape and the target migratory animal. We initially constructed a <i>δ</i><sup>15</sup>N<sub>Base</sub> isoscape in the North Pacific by bulk and compound-specific isotope analyses of copepods (<i>n</i> = 360 and 24, respectively). We then determined retrospective <i>δ</i><sup>15</sup>N<sub>Base</sub> values of spawning chum salmon (<i>Oncorhynchus keta</i>) from their vertebral centra (10 sections from each of two salmon), and estimated their migration routes by using a state-space model. Our isotope tracking method successfully reproduced a known chum salmon migration route between the Okhotsk and Bering seas, and our findings suggest the presence of a migration route to the Bering Sea Shelf during a later growth stage.

Alkyl lipid distribution, elemental composition and compound-specific 14C isotope composition in marine and terrestrial sedimentary archives from sub-Antarctic South Georgia
<p>The dataset comprises elemental data, alkyl lipid data and radiocarbon (14C) data that was obtained on sediment samples from sub-Antarctic South Georgia. The sediments were collected from a range of different sites, including lakes, peat deposits, a marine inlet and a fjord during RV Polarstern expedition PS81 in 2013. More details on the study sites, sampling and data evaluation can be found in Berg et al. (submitted manuscript to JGR Biogeochemistry).</p>
Assessment of compound-specific fatty acid d13C and d2H values to track fish residency and mobility in a small subalpine catchment
<p><span>Methods for identifying origin, movement, and foraging areas of animals are essential for understanding ecosystem connectivity, nutrient flows, and other ecological processes. Telemetric methods can provide detailed spatial coverage but are limited to minimum body size of specimen for tagging. In recent years, stable isotopes have been increasingly used to track animal migration by linking geophysical isotope landscapes called "isoscapes". However, compared to telemetric methods, the spatial resolution of bulk stable isotopes is low.</span></p> <p><span>Here we examined a novel approach by evaluating the use of compound-specific hydrogen and carbon stable isotopes of fatty acids (δ</span><sup><span>2</span></sup><span>H<sub>FA</sub> and </span><span>δ<sup>13</sup></span><span>C<sub>FA</sub>) from liver, muscle, brain, and eye tissues for identifying site-specificity of fish from a sub-alpine river catchment. We analysed 208 fish (European bullhead, rainbow trout, and brown trout) collected in 2016 and 2018 at 15 different sites.</span></p> <p><span>δ<sup>13</sup></span><span>C<sub>FA</sub> values of these fish tissues correlated more amongst each other than those of </span><span><span>δ</span><sup><span>2</span></sup><span>H<sub>FA</sub></span> values. Both </span><span><span>δ</span><sup><span>2</span></sup><span>H<sub>FA</sub></span> and </span><span><span>δ<sup>13</sup></span><span>C<sub>FA</sub></span> values showed tissue-dependent isotopic fractionation, while fish taxa had only small effects. The highest site-specificity was for </span><span>δ<sup>13</sup></span><span>C<sub>DHA</sub> values, while the </span><span>δ<sup>2</sup></span><span>H isotopic difference between LIN and ALA resulted in the highest site-specificity. Using linear discrimination analysis of FA isotope values, over 90 % of fish could be assigned to their location of origin, however, the accuracy dropped to about 56 % when isotope data from 2016 were used to predict the sites for samples collected in 2018, suggesting temporal shifts in site specificity of </span><span><span>δ</span><sup><span>2</span></sup><span>H<sub>FA</sub></span> and </span><span>d</span><span>13</span><span>CFA. However, predictive results were still higher than site specificity compared to bulk tissue isotopes for a single time point. In summary, compound-specific isotope analysis of fatty acids may become a highly effective tool for assessing fine and large-scale movement and foraging areas of animals.</span></p>

Dietary availability determines metabolic conversion of long-chain polyunsaturated fatty acids in spiders: a dual compound-specific stable isotope approach
<p>The following dataset contains fatty acid contents (in mg.g<sup>-1</sup> and in %), stable isotopes (‰), and compound specific isotopic analyses of carbon and hydrogen (‰) data for insects (terrestrial and semi-aquatic) and spiders collected around Lake Lunz (47°85'N, 15°05'E), Austria from June to September 2020. Measurements were done after storage at -80°C for 2 hours, and freeze drying (24h), followed by taxonomic identification. Analytical details can be found in "Dietary availability determines metabolic conversion of long-chain polyunsaturated fatty acids in spiders: a dual compound-specific stable isotope approach" by Mathieu-Resuge, Margaux; Pilecky, Matthias; Twining, Cornelia; Martin-Creuzburg, Dominik; Parmar, Tarn-Preet; Vitecek, Simon; Kainz, Martin.
