Data from: Integrating machine learning with otolith isoscapes: reconstructing connectivity of a marine fish over four decades
<p>Stable isotopes are an important tool to uncover animal migration. Geographic natal assignments often require categorizing the spatial domain through a nominal approach, which can introduce bias given the continuous nature of these tracers. Stable isotopes predicted over a spatial gradient (i.e., isoscapes) allow a probabilistic and continuous assignment of origin across space, although applications to marine organisms remain limited. We present a new framework that integrates nominal and continuous assignment approaches by (1) developing a machine-learning multi-model ensemble classifier using Bayesian model averaging (nominal); and (2) integrating nominal predictions with continuous isoscapes to estimate the probability of origin across the spatial domain (continuous). We applied this integrated framework to predict the geographic origin of the Northwest Atlantic mackerel (<em>Scomber scombrus</em>), a migratory pelagic fish comprised of northern and southern components that have distinct spawning sites off Canada (northern contingent) and the US (southern contingent), and seasonally overlap in US fished regions. The nominal approach based on otolith carbon and oxygen stable isotopes (δ<sup>13</sup>C/δ<sup>18</sup>O) yielded high contingent classification accuracy (84.9%). Contingent assignment of unknown-origin samples revealed prevalent, yet highly varied contingent mixing levels (12.5–83.7%) within the US waters over four decades (1975–2019). Nominal predictions were integrated into mackerel-specific otolith oxygen isoscapes developed independently for Canadian and US waters. The combined approach identified geographic nursery hotspots in known spawning sites, but also detected geographic shifts over multi-decadal time scales. This framework can be applied to other marine species to understand migration and connectivity at high spatial resolution, relevant to management of unit stocks in fisheries and other conservation assessments.</p>
FIGURE 4 in Marine and freshwater fishes of Alabama: a revised checklist and discussion of taxonomic issues
FIGURE 4. Summary of state status (A), habitat classifications (B), and collection localities by habitat classification (C) of marine and freshwater fishes of Alabama in the present checklist. Non-duplicate collection localities for species that were classified as primarily freshwater ('F' designations), primarily marine ('M' designations), and freshwater and marine ('F, M' designations) in habit are summarized in a Venn diagram in panel C, where the total number in each area sums to the total number of unique collection localities in our final dataset (n = 10,325). Abbreviations: Exstate, extirpated from the state; F, freshwater; I, introduced species; M, marine; N, native; N/A, not applicable (no state status because species does not occur within state borders); Reint, reintroduced in state.
