This long‐standing, unresolved topic ecology evolution has renewed importance because changing environmental conditions are driving range expansions that may necessitate rapid evolutionary responses.

To test for adaptation, we performed series experimental crosses adults collected from historical (HxH) recently (ExE), conducted RNA‐Seq on offspring reared garden environment. We identified 2770 differentially expressed genes (DEGs) between 54 samples either only (HxH offspring) or (ExE ancestry. Using SNPs called directly DEGs, assigned known origin back unprecedented accuracy marine species (92.6% 94.5% HxH ExE offspring, respectively).

As anthropogenic disturbances rapidly change natural environments, species must respond to new selective pressures shaping rates of reproduction, growth, and mortality. One example is intense fisheries harvest, which can drive the evolution heavily fished populations toward maturation at smaller sizes younger ages. Changes in have often been measured using probabilistic reaction norms (PMRNs), were originally designed control for phenotypic plasticity while allowing detection maturation. However, multiple studies highlighted issues with PMRN estimation, particularly respect their accuracy when parameterized sparse data or applied experiencing myriad environmental stressors. We used a three-decade time series Laurentian Great Lakes yellow perch (Perca flavescens Mitchill) develop novel, hierarchical Bayesian estimation method that explicitly account these conceptual issues. Our results indicate commercial fishing was primary driver this population, relaxation harvest pressure via closure fishery late 1990s resulted adaptation older ages larger within 2-3 generations. Future pairing methods genome-wide will help reveal genetic underpinnings maturation, could lead avenues integrating PMRNs into management policy.

Abstract How to identify the drivers of population connectivity remains a fundamental question in ecology and evolution. Answering this can be challenging aquatic environments where dynamic lake ocean currents coupled with high levels dispersal gene flow decrease utility modern genetic tools. To address challenge, we used RAD‐Seq genotype 959 yellow perch ( Perca flavescens ), species an ~40‐day pelagic larval duration (PLD), collected from 20 sites circumscribing Lake Michigan. We also developed novel, integrative approach that couples detailed biophysical models eco‐genetic agent‐based generate “predictive” values differentiation. By comparing predictive empirical differentiation, estimated relative contributions for known (e.g., currents, behavior, PLD). For main basin populations (i.e., largest contiguous portion lake), found led low overall differentiation among F ST = 0.003). far best predictors were matrices derived periods time when there strong highly dispersive currents. Thus, these are driving patterns basin. northern southern slightly divergent one another, while those Green Bay 0.11). integrating genome‐wide data, illustrate identified systems.

Abstract Elucidating physical transport phenologies in large lakes can aid understanding of larval recruitment dynamics. Here, we integrate a series climate, hydrodynamic, biogeochemical, and Lagrangian particle dispersion models to: (1) simulate hatch fish larvae throughout an illustrative lake, (2) evaluate patterns historic potential future climate‐induced transport, (3) consider consequences for overlap with suitable temperatures prey. Simulations demonstrate that relative offshore increases seasonally, shifts toward occurring earlier during relatively warm simulations. Intra‐ inter‐annual trends were robust to assumed pelagic duration precise location timing hatching. Larvae retained nearshore generally encountered more favorable zooplankton densities compared transported offshore. Larval exploitation resources under climate change may depend on concomitant shift spawning times advance transport.

ABSTRACT Optimal egg size theory implies that female organisms balance between fecundity and individual offspring investment according to their environment. Past interspecific studies suggest fishes in large marine systems generally produce smaller eggs than those small freshwater systems. We tested whether intraspecific variation reflected a similar pattern by comparing among yellow perch ( Perca flavescens ) populations inhabiting range of system sizes. In 2018, 2019, 2023, we collected samples from 12 locations ranging surface area 37 5,390,492 ha. First, found diameter significantly increased with maternal total length five eight individually populations. After accounting for these effects, significant interaction, where females larger lakes, such as the main basins Lakes Erie Michigan, produced inland greatest differences were demonstrated greater length. This largest is consistent comparisons fishes. However, examining single species across vastly different environments, able support theoretical expectations should vary environmental conditions controlling early‐life resource acquisition competition.
