Relative role of operational patterns and environmental conditions on cookie cutter shark damage in the Hawai‘i longline fishery

Suca, Justin J. ;

Kobayashi, Donald

2025 | Marine Ecology Progress Series, 775, 119-135 | pdf

Cookie cutter sharks Isistius spp. (nahunaiki) are a small shark species that act as a micropredator for large pelagic organisms. Little is known about these sharks due to their cryptic behavior, resulting in most inferences about their distribution coming from patterns in the wounds they leave on prey. Here, we used documentation of these cookie c ...

Little is known about these sharks due to their cryptic behavior, resulting in most inferences about their distribution coming from patterns in the wounds they leave on prey. Here, we used documentation of these cookie cutter shark bites on fish caught in the Hawai‘i longline fishery, coupled with catch location and timing, to better understand how fisher behavior and environmental conditions are associated with cookie cutter shark bites. Specifically, we analyzed patterns in cookie cutter shark bites for the nighttime shallow-set sector targeting swordfish Xiphias gladius (a‘u kū) and the daytime deep-set sector targeting bigeye tuna Thunnus obesus (‘ahi po‘onui). Our results indicated that cookie cutter shark bites primarily occurred on hooked fish when operations extended longer into nightfall, during low lunar illumination, and along the edges of the North Pacific subtropical gyre. Bites were more common on average in the shallow-set fishery than the deep-set fishery, likely due to the nearly full nighttime operational window. The frequency of cookie cutter shark bites on fish caught in the deep-set sector has increased over time due to fishing extending further into nighttime hours. Our findings provide insight into the ecology of cookie cutter sharks, context for the increasing frequency of cookie cutter shark bites in the deep-set Hawai‘i longline fishery, and important information for fishers regarding the potential costs of increased effort leading to fish damaged by cookie cutter shark bites.

AB - Prescribed wildland and agricultural fires are common in the eastern United States (U.S.), but their small size and short durations have led polar-orbiting satellite data sets to underestimate their emissions due to omission. The higher temporal resolution of the GOES-16 Advanced Baseline Imager (ABI) improves fire detection, enabling development of a new biomass burning emissions inventory: GOES Eastern U.S. Fire Emissions (GEUFE, pronounced “goofy”). GEUFE is based on geostationary fire radiative power (FRP) observations, incorporates improved crop type classification for agricultural fires, and includes a new emission factor (EF) compilation for 16 land cover types in the eastern U.S., including forest, crop, and grassland types that differ markedly from globally reported EF values. GEUFE provides daily estimates of dry matter (DM) consumption and emissions of CO2, CO, NOx, NH3, SO2, organic carbon (OC), black carbon (BC), and fine particulate matter (PM2.5) at 2 km resolution. An intercomparison of 10 biomass burning emissions inventories (GEUFE, GBBEPx, QFED, NEI-2017, RAVE, FEER, VFEI, GFAS, FINN, GFED) showed that OC estimates in the eastern U.S. during August 2019–July 2020 ranged from 0.05 to 1.32 Tg yr−1, with both EFs and DM consumption driving the large spread in aerosol estimates. GEUFE, at 0.64 Tg yr−1, is at the high end of this range due both to region-specific EFs and continuous GOES-16 monitoring, reducing missed short-lived fires. GEUFE is a process-based inventory that eliminates reliance on empirical scaling factors, such as QFED's aerosol optical depth-based adjustments, while explaining previously inferred “missing emissions” from small fires.

AU - Hayes, Sean A. AB - Entanglement is one of the primary anthropogenic threats to the North Atlantic right whale (Eubalaena glacialis; right whale) whose habitat overlaps fixed-gear fishing grounds in the Northwest Atlantic with entanglements representing around half of the mortality and serious injury incidents. Right whale mortality has reached levels that require intervention under the Marine Mammal Protection Act, creating the need for a tool that can compare the relative benefits of risk reduction management measures under consideration. To address this need, National Marine Fisheries Service developed a Decision Support Tool (DST) which has undergone continued development since 2019 and is introduced here as the Woods Hole Analysis of Line Entanglement (WHALE) DST. This tool calculates relative risk as the product of (1) the density of endlines associated with fixed-gear fishing at a given location and month, (2) the entanglement severity that endlines pose based on the specific configuration of the gear, and (3) the estimated density of right whales at the given location and month. The model is novel in its capacity to quantify reductions in entanglement risk by simultaneously assessing a variety of overlapping management actions such as time/area closures, weakening of rope, and other adaptations of gear configurations that reduce endlines or make them less dangerous. We demonstrate the functionality of the WHALE DST by applying management actions implemented in 2021. While originally developed for right whale conservation, the WHALE DST is adaptable for evaluating spatiotemporal entanglement risk reduction for other protected species management and marine spatial planning activities.

AB - Phytoplankton are a diverse group of photosynthetic microorganisms critical to global biogeochemical processes. Abundance, distribution, and size class structure of phytoplankton are controlled in part by environmental factors, driven by the ocean's physical and biogeochemical processes, which are impacted by climate change. How these forcing factors vary across thermal regimes in the U.S. Northeast Shelf Ecosystem (NES), a rapidly warming region where multiple marine heatwaves have occurred, is unknown. Environmental predictors of phytoplankton abundance and size class fraction variability were characterized using multivariate modeling via partial least squares regression (PLSR) and predictor significance determined via variable influence on projection (VIP) scores. Variability in size class abundance in the northern NES is primarily linked to the nutricline, while in the southern NES, it is more strongly associated with water column stability (sea surface temperature and salinity). Temporally, the cooler regime (approx. 1997–2010) is the most different from all other time periods and each marine heatwave results in specific differences for parameters from other heating conditions. Furthermore, chlorophyll and microplankton exhibit similar VIP scores to nano‐ and picoplankton, but inverse PLSR coefficients. Microplankton are less suited to warmer conditions and are more strongly associated with salinity and nutrient variability, which are coupled with reduced vertical mixing in the water column. Phytoplankton variability associated with changing oceanographic conditions will impact regional biogeochemical processes with consequences to the marine carbon cycle and food web.

AU - Thomas, Len AB - Exploring solutions to expanding industrial activities and climate change requires assessments of the combined effects of multiple stressors on wildlife populations. We present a spatially explicit state-space model for the health, survival, reproduction, and somatic growth of individuals in a long-lived, wide-ranging species. The model is applied to critically endangered North Atlantic right whales (Eubalaena glacialis) to investigate the combined effects of three primary stressors affecting the species' viability: entanglements in fishing gear, vessel strikes, and prey availability. We estimate exposure to these stressors in space and time and assess how their effects may combine in the pathway from exposure to vital rates. Results suggest that changes in whale distribution after 2010 led to increased entanglement risk. Poorer prey conditions were associated with an increased effect of carrying fishing gear, but, overall, results on combined effects were not conclusive and depended on model formulation. We also incorporated the estimated effects of stressors into a population viability analysis to explore alternative scenarios of stressor reduction. This integrated analysis highlighted the importance of the declining trend in maximum body length and its effect on reproduction, in addition to the documented impact of entanglements on survival. Model development and application elucidated critical data needs and the influence of underlying mechanistic assumptions. Specifically, models for the combined effects of stressors hinge on the availability of extended longitudinal measurements of individual health and life history outcomes, extensive datasets on the spatiotemporal distribution of stressors, and information on individual space use affecting rates of exposure to stressors. Lessons from this data-rich case study will support the generalization of the modeling approach to other long-lived species where measuring the population-level consequences of multiple stressors directly is unfeasible.

AU - Gedamke, Jason AB - The National Oceanic and Atmospheric Administration (NOAA), in partnership with the U.S. National Park Service (NPS), established the Ocean Noise Reference Station Network (NRS) in 2014 as a foundational component of NOAA’s Ocean Noise Strategy. This long-term effort aims to characterize baseline ocean ambient sound conditions across diverse marine environments and to inform management of noise impacts on protected species and habitats within U.S. waters. The NRS is now composed of 13 autonomous passive acoustic monitoring stations strategically positioned across the U.S. Exclusive Economic Zone (EEZ), extending from Arctic regions to tropical waters in depths ranging from 33 to 4,790 m. These locations include several National Marine Sanctuaries and National Parks, such as the recently designated Chumash Heritage National Marine Sanctuary off the coast of California. Each station is equipped to continuously sample low-frequency underwater sound at five kHz, enabling the detection of anthropogenic, geophysical, and biological acoustic signals. To date the network has sampled over 72 years of calibrated acoustic data. The spatial breadth and consistent methodology of the NRS allow for comparative acoustic assessments across diverse marine ecosystems. In addition to applied research functions, the NRS has served as a platform for education and training, offering opportunities for students to develop skills for marine science and data analysis. Looking forward, the NRS project team is focused on network expansion, improved data delivery, and broader integration with collaborative scientific initiatives. NRS recordings are being archived in partnership with NOAA’s National Centers for Environmental Information to enhance accessibility and long-term utility. Efforts are underway to develop standardized metadata and summary products to accompany raw audio files, making the data more usable for a wide range of stakeholders in the ocean science community. The NRS is evolving into a fully integrated national framework for ocean sound monitoring that supports scientific inquiry, management decision-making, national security interests, and public engagement with ocean acoustic environments.

One of these fisheries targeted yellowtail flounder (Limanda ferruginea), which at its peak caught over 21 000 mt a year. However, the stock has fluctuated, with periods of high abundance (1970s and 2000s) and low stock size (1990s and 2020s). A review published twenty years ago documented the collapse of the stock in the 1990s and subsequent recovery in the 2000s, hypothesizing the major reason for recovery was bilateral science and successfully coordinated management intervention. Unfortunately, by the time that review was published, the stock had started to decrease again and collapsed in the 2010s. We provide an updated historical review of the fishery and past stock assessments. We conduct new analyses of empirical indicators of spatial distribution and growth for Georges Bank yellowtail flounder and project the stock into the future using the most recent stock assessment. Results suggest that fishing was the likely cause of initial stock depletion while environmental changes, particularly bottom temperature, has limited recovery in recent years. Projections suggest that the population can increase in the future but its ability to increase is related to bottom temperature on Georges Bank. These results give insight into the dynamics an iconic New England fishery and stock, as well as, provide a unique opportunity to study the fluctuations of a stock through multiple periods of recovery and collapse.

AB - Top predators influence ecological communities in part through the prey they consume. Prey preferences often shift throughout the year, reflecting both seasonal and geographic patterns of habitat use and the relative abundance of preferred prey species. Killer whales (Orcinus orca) are top predators in the marine ecosystem, and understanding their diet is critical to assess their ecological impacts and role. In this study, we examine the diet of the southern Alaska resident killer whale population across three major foraging hotspots. We leverage two complementary sampling methods—morphological ID and genetic metabarcoding—to reveal strong spatiotemporal patterns in diet from May through September. Chinook, chum, and coho salmon were each important prey resources in different locations and times, with consistent dietary contributions from Pacific halibut, arrowtooth flounder, and sablefish. Our results reveal a diverse, location-specific, and strongly seasonal foraging strategy in this top predator and highlight the increased resolution provided by using ensemble techniques to characterize foraging behavior. Effective conservation and management of this population will depend on broad spatiotemporal sampling to accurately characterize foraging ecology.

In the Eastern Bering Sea, climate change threatens communities through reduced economic opportunities and food security in fishing-reliant areas. We apply a risk assessment framework integrated with statistical modelling and regionally downscaled ocean models to hindcast and project the distribution of adult and juvenile Pacific cod abundance in the Eastern Bering Sea under two shared socioeconomic pathways (SSP1-2.6 and SSP5-8.5), leveraging commercial fisheries catch data and publicly available socioeconomic information to assess the exposure and sensitivity of Alaska fishing communities’ to the geographical redistribution of Pacific cod. To compare risk among seven federally recognized Alaska census areas, we adapt a recognized framework that integrates hazards, sensitivity, and exposure as equally weighted components of risk. To assess how distributions and relative risk may shift from both historic and more recent abnormal environmental conditions, we compare future projections against two contrasting climate baselines: a ‘normal’ period (1980–2000) and a recent abnormally warm period (warm years post-2000). Projections of Pacific cod distributions across multiple climate scenarios indicate a progressive shift in abundance from the southern to the northern Eastern Bering Sea. The extent of this geographical change, coupled with lower adaptive capacity and higher dependence on this fish as a resource, results in heightened risk for southern Eastern Bering Sea communities. Our findings highlight the need for adaptive, place-based fisheries management strategies that are tailored to regional sensitivities to projected shifts in marine resources under a changing climate.

David AU - Blanchong, Julie A. AB - White-tailed deer (Odocoileus virginianus) are the most abundant and widespread cervid in North America. Genetic data are used as a tool to monitor populations and make management decisions for this game species. However, the development and use of genomic tools that can generate a set of markers suitable for longitudinal genomic data collection, whether for management purposes or to study the demographic and evolutionary processes of widely distributed species, have been challenging. This is mainly due to the cost required to fully implement and interpret the data produced. Here, we generated whole genome resequencing data for 44 free-ranging deer from three regions in their central and eastern North American range and identified over 89 million single nucleotide polymorphisms (SNPs). We used a subset of these SNPs to develop two nested SNP tools, a high-density array (702,183 SNPs) and a medium-density array (72,723 SNPs) to support deer and chronic wasting disease (CWD) management and research. SNPs were selected to ensure an even distribution across scaffolds of the reference genome and include SNPs associated with CWD susceptibility. Using genotyping results for 469 deer from 15 states in the US and Mexico generated by the high-density array and 1335 deer from 18 states generated by the medium-density array, we assessed genotyping success across different populations and explored some insights into population structure. These genomic tools offer a standard set of markers that will enable researchers and managers to address important questions related to white-tailed deer and CWD management. Our SNP arrays also offer the opportunity to examine aspects of white-tailed deer ecology and evolutionary history that were previously difficult to address.

Christopher AB - Anthropogenic release of CO2 and its subsequent dissolution in the oceans results in a decrease in the pH of seawater, known as ocean acidification, which can negatively affect marine organisms. Little is known about the response of snow crab, Chionoecetes opilio, to reduced pH. Juvenile snow crab were captured in the Bering Sea and exposed to three different pH treatments (Ambient (pH ∼7.95), pH 7.8, and pH 7.5) for 396 days at a constant temperature of 4 °C with thirty crabs randomly assigned to each treatment. Crabs were checked daily for molting or mortality. Wet mass and carapace morphometrics were measured after every molt. Reduced pH did not affect the intermolt duration, the carapace width after each molt, or wet mass of the crabs after each molt, giving no indication that growth rate was changed by reduced pH. There also was no change in morphometrics caused by reduced pH. However, the mortality rate of crabs held at pH 7.5 was 40 % higher than those held at pH 7.8 or Ambient. Such a substantial increase in mortality without accompanying sublethal effects is surprising; individuals susceptible to reduced pH might have died early in the experiment, or that differences in growth rate might have become apparent with longer exposure. Regardless, juvenile snow crab are somewhat sensitive to ocean acidification, although, consistent with studies at other life-history stages, snow crab may be more resistant to changes in pH than other Alaska crab species.

AB - Effective monitoring is fundamental to estimating wildlife population parameters with a level of accuracy and precision that is adequate to inform management decisions. However, managers must balance trade‐offs between the costs of monitoring and the resulting data quality to identify cost‐effective monitoring survey designs. As such, evaluating the expected performance of monitoring surveys relative to monitoring objectives prior to survey implementation is critical. In this study, we present a simulation framework for examining the accuracy and precision of age‐specific survival estimates and the probability of detecting a change in survival within the context of mark–resight monitoring programs. We consider 90 survey designs that vary across marked cohort size, marking frequency, study duration, and resight probability (i.e., detection of marked individuals). We apply this approach to the design of a monitoring program for Steller sea lions (Eumetopias jubatus), which is complicated by heterogeneity in rookery accessibility, population sizes, and abundance trends across the species' range. To identify cost‐effective survey designs in the absence of actual survey costs, we evaluated performance with respect to a relative‐costs schema. Our results highlight survey designs that reliably meet pre‐defined precision targets, with precision and accuracy strongly affected by marked cohort size, marking frequency, and study duration. We found that historical mark–resight survey effort for Steller sea lions has been sufficient to reliably achieve precision targets for younger age class survival probabilities only for rookeries where abundance has been stable or increasing. In contrast, the probability of achieving survival estimates with target levels of precision at rookeries where abundance has been declining is low (<25%) due to smaller marked cohort sizes, less frequent marking at remote sites, and fewer years of available data. Our results indicate that the precision of survival estimates for subpopulations of conservation concern can be improved by longer‐term monitoring, although the constraints of monitoring small populations may limit the ability of biologists to detect changes in population dynamics on management‐relevant time horizons. Our survey design evaluation framework can be applied in a variety of contexts to assist natural resource managers in developing cost‐effective monitoring programs.

This paper examines direct sea surface temperature (SST) measurements of the skin (SSTskin) and near-surface SST (SSTdepth), and wind speeds measured during the Sub-Mesoscale Ocean Dynamics Experiment (S-MODE) along with derived bulk fluxes. We evaluate the modulation of the net heat flux, wind speed, and skin cooling across SST fronts and the ability of the COARE bulk flux algorithm to reproduce this variability. Bulk flux computations can be performed directly from a radiometric SSTskin, or more commonly, from the SSTdepth provided that the depth of the SST measurement is corrected for cool skin and diurnal warming effects. Both types of SST were measured during S-MODE allowing for (a) an assessment of the importance of having a SSTskin for a direct flux evaluation in frontal regions, and (b) an evaluation of the accuracy of the cool skin and diurnal warming corrections within COARE for the indirect bulk flux computation. The ocean-atmosphere feedback over the sampled S-MODE submesoscale front suggested that the ocean was indeed forcing the atmosphere, mainly through the surface net heat losses, while the wind response to changes in SSTskin was irregular. Testing of the COARE algorithm suggested that indirect bulk fluxes had sufficient accuracy to close the heat budget over the front.

Species-specific responses to temperature provide insight into potential co-occurrence or competitive advantage between Arctic and boreal species. Ocean acidification may also lead to unique species-specific responses. At the Pacific–Arctic interface, larval distributions of the boreal Pacific cod (Gadus macrocephalus) are increasingly overlapping with those of Arctic cod (Boreogadus saida). We assessed larval metabolic capacities by measuring metabolic enzyme activities of citrate synthase (CS; aerobic metabolism), lactate dehydrogenase (LDH; anaerobic metabolism), and β-hydroxyacyl CoA dehydrogenase (HOAD; fatty acid metabolism). Throughout early development, Pacific cod enzyme activities, including glycolytic capacity, were higher, and fatty acid metabolism lower than Arctic cod enzyme activities. These responses may reflect a more active larval lifestyle of Pacific cod. Separately, larvae were reared in multiple temperatures (Pacific cod: 3, 6, 10°C; Arctic cod 1.8, 5, 7.3°C) and pCO2 levels (ambient = ~350 μatm; high = ~1500 μatm). At the cold temperature, Pacific cod enzyme activities were higher than at the control temperature, indicating they were acclimating but less cold adapted than Arctic cod. Arctic cod HOAD activity and LDH:CS ratio were elevated under warmer temperatures suggesting increased energy demand. Elevated pCO2 levels only affected larvae at their control temperature and resulted in decreased Pacific cod HOAD activity and increased Arctic cod CS and HOAD activities. This indicates differing sensitivities to ocean acidification between the species. Overall, Pacific cod may continue to be constrained in their northern habitat by cold temperatures, but under slight warming to optimal growing temperatures, Pacific cod will have competitive advantage over Arctic cod.

TY - AU - Trudeau, Gabrielle A. AU - Lyon, Mark AU - Lowell, Kim AU - Dijkstra, Jennifer A. AB - Accurate, scalable mapping of coral reef habitats is essential for monitoring ecosystem health and detecting change over time. In this study, we introduce a novel mathematically based nonlinear spectral unmixing method for benthic habitat classification, which provides sub-pixel estimates of benthic composition, capturing the mixed benthic composition within individual pixels. We compare its performance against two machine learning approaches: semi-supervised K-Means clustering and AdaBoost decision trees. All models were applied to high-resolution PlanetScope satellite imagery and ICESat-2-derived terrain metrics. Models were trained using a ground truth dataset constructed from benthic photoquadrats collected at Heron Reef, Australia, with additional input features including band ratios, standardized band differences, and derived ICESat-2 metrics such as rugosity and slope. While AdaBoost achieved the highest overall accuracy (93.3%) and benefited most from ICESat-2 features, K-Means performed less well (85.9%) and declined when these metrics were included. The spectral unmixing method uniquely captured sub-pixel habitat abundance, offering a more nuanced and ecologically realistic view of reef composition despite lower discrete classification accuracy (64.8%). These findings highlight nonlinear spectral unmixing as a promising approach for fine-scale, transferable coral reef habitat mapping, especially in complex or heterogeneous reef environments.

Despite advancements in computational power and growing interest in the field, underwater image analysis remains a significant challenge, especially in highly turbid environments. This study is the first to assess the potential of texture descriptors for classifying benthic species and habitats using turbid underwater imagery. Underwater images were collected in SE Baltic Sea reefs (4.4–42.2 m depth) using a drop-down camera. A total of sixteen textural descriptors were tested, of which three were selected for the CatBoost ML model image classification task. The model's performance was evaluated using annotated images provided by field experts. Among these, the MRELBP (Median Robust Extended Local Binary Pattern) algorithm achieved the highest overall performance. For individual classes, the best image classification results were achieved for large blue mussels by the LMP (Local Morphological Pattern) algorithm (F1 score: 0.72 ± 0.18) and small blue mussels (F1 score: 0.66 ± 0.13) by MRELBP. For lithological classes, sand was classified with the highest accuracy by MRELBP (F1 score: 0.69 ± 0.23). Model coverage estimates were acceptable in 49 % of the images, with blue mussels being the most suitable for evaluation. The results demonstrate textural descriptors capabilities in classifying real-world underwater images.

TY - AU - Lowell, Kim AB - High data volumes and the time required to process LiDAR point clouds to identify bathymetric points create a potentially large lag between data acquisition and use for shallow water mapping. In this study, a method was developed for a priori identification of areas (500 m by 500 m ‘tiles’) in a data set that are unlikely to contain bathymetric pulse returns and therefore do not need to be processed. Using an airborne LiDAR data set centred on Key West, Florida (United States) containing 1374 tiles, a logistic regression model was developed to predict if a tile contained extractable bathymetry (according to standard operating procedures of the United States National Oceanic and Atmospheric Agency (NOAA)) using quantifiable characteristics of depth frequency histograms as predictors. Results indicated that tiles that do not contain extractable bathymetric pulse returns could be identified with 90% accuracy. A post-modelling ‘spatial reassignment’ of individual tiles based on the characteristics of neighbouring tiles provided only a minor accuracy improvement. The methodology was validated on a Miami Beach LiDAR data set containing 120 tiles. Results were comparable to the Key West results, although the logistic regression model had to be re-calibrated for Miami Beach. To operationalize the results and eliminate the need to process all tiles a priori, a progressive tile-sampling approach is suggested. Furthermore, operational use of this a priori tile screening approach also requires consideration of expected uses of bathymetric maps and risk tolerance relative to the different consequences of false negative (FN) and false positive (FP) errors. For the Key West data set comprised of 1374 tiles of which 36% did not contain extractable bathymetry, screening tiles and then processing non-excluded tiles for bathymetric extraction was estimated to reduce total time by 489 hours (161 human/manual hours and 328 computer hours) compared to not screening and processing all 1374 tiles.

SDB was developed for three small areas (500 m-by-1500 m) near Key West Florida (United States) that varied in depth and geomorphometric complexity. Data employed were 2016 and 2019 airborne lidar and three 2016 and four 2019 Landsat images. The modelling methodology was a widely used quasi-empirical linear regression-based approach. Local accuracy of SDB depth change – which was expected to be pronounced between 2016 and 2019 due to the occurrence of Category 5 Hurricane Irma in 2017 – was also calculated and examined. The global correlation (R2) between lidar-based depth and SDB for 2016 and 2019 varied from about 0.1 to 0.9 which produced relative (to depth) root mean square errors (RMSEs) between 5% and 25%. No image was consistently best for all three areas nor for either 2016 and 2019. SDB-based depth change was poorly correlated to the reference lidar-based depth change for all three areas. Spatial depiction of SDB accuracy showed considerable variability even within the three relatively small areas employed for 2016 and 2019 SDB depth estimates and 2016–2019 SDB depth change estimates.

TY - AU - Amirthalingam, Pavithiran AU - Greaves, Samuel AU - O’Malley, Joseph M. AU - Schemmel, Eva AU - Marciante, Victoria AU - Gaither, Michelle R. AB - Coral reefs are patchily distributed across vast areas of Earth’s tropical and subtropical oceans. Dispersal of individuals between habitat patches is essential to maintain genetic connectivity between subpopulations and plays an important role in population persistence. While the biotic and abiotic factors that influence patterns of dispersal have received a great deal of attention, fundamental questions about genetic connectivity in marine systems remain largely unanswered. Micronesia, in the northern central Pacific, is comprised of over two thousand islands that stretch across 7,400,000 km2 and is thought to provide stepping-stones for dispersal between the central and western Pacific. Despite its size and importance, few phylogeographic studies have focused on Micronesia and none have been conducted in the Mariana Archipelago in northern Micronesia. Here we examined population structure in the peacock grouper Cephalopholis argus across the region. Based on ~15,000 SNPs we found three population clusters: the Mariana Archipelago, western Micronesia (Palau) and eastern Micronesia (Pohnpei and Kwajalein). These findings are largely concordant with two previous studies and taken together they highlight the influence of the North Equatorial Current and the North Equatorial Countercurrent in the Central Pacific and indicate that perhaps broad scale ecosystem level processes and not species-level traits are driving population patterns in the region. Furthermore, we detected little genetic structure across 800 km of the Mariana Archipelago and found that rates of gene flow among the islands were higher in the north but diminished at Anatahan and continued to decrease southward toward Saipan and Guam. Our data also indicate that the Mariana Islands receives more migrants from the Central Micronesian islands to the south then it exports, and that Guam, the southernmost island in the archipelago, may serve as an important gateway from the Central Pacific into the Mariana Islands.
