Abstract Some of the longest and most comprehensive marine ecosystem monitoring programs were established in Gulf Alaska following environmental disaster Exxon Valdez oil spill over 30 years ago. These have been successful assessing recovery from impacts, their continuation decades later has now provided an unparalleled assessment responses to another newly emerging global threat, heatwaves. The 2014–2016 northeast Pacific heatwave (PMH) was lasting globally past decade, with some cooling,...
Summary Androgenetic doubled haploid progeny produced from a cross between the Oregon State University and Arlee clonal rainbow trout ( Oncorhynchus mykiss ) lines, used for previous published map, were to update map with addition of more amplified fragment length polymorphic (AFLP) markers, microsatellites, type I allozyme markers. We have added than 900 bringing total number 1359 genetic markers sex phenotype including 799 Eco RI AFLPs, 174 Pst 226 72 VNTR, 38 SINE 29 known genes, 12...
The Alaska CLimate Integrated Modeling (ACLIM) project represents a comprehensive, multi-year, interdisciplinary effort to characterize and climate-driven changes the Eastern Bering Sea ecosystem, from physics fishing communities. Results ACLIM are being used understand how different regional fisheries management approaches can help promote adaptation sustain fish shellfish populations inform managers fishery dependent communities of risks associated with future climate scenarios. relies on...
Poleward species range shifts have been predicted to result from climate change, and many observations confirmed such movement. may represent a homogeneous shift in distribution, seasonal northward movement of specific populations, or colonization processes at the poleward edge distribution. The ecosystem Bering Sea has changing along with climate, moving an arctic subarctic system. Several fish observed farther north than previously reported increasing abundances. We examined one these...
Genetic population structure of Pacific cod, Gadus macrocephalus , was examined across much its northeastern range by screening variation at 11 microsatellite DNA loci. Estimates F ST (0.005 ± 0.002) and R (0.010 0.003) over all samples suggested that effective dispersal is limited among populations. divergence highly correlated with geographic distance in an isolation-by-distance (IBD) pattern along the entire coastal continuum Ocean (~4000 km; r 2 = 0.83), extending from Washington State...
Variation at the mitochondrial cytochrome c oxidase subunit I (mt‐COI) gene was examined in 15 species of North Pacific skates. Thirteen had unique sequences, indicating that a DNA‐based barcoding approach may be useful for identification.
Abstract We discuss the development and characterization of 40 polymorphic rainbow trout ( Oncorhynchus mykiss ) microsatellite loci. used enriched libraries to isolate 14 dinucleotide, seven trinucleodide, eight compound di/tetranucleotide, 11 tetranucleotide These markers will be useful for selective breeding via marker‐assisted selection, population genetics studies, parentage analysis, have already been genome mapping.
Pleistocene ice-ages greatly influenced the historical abundances of Pacific cod, Gadus macrocephalus, in North and its marginal seas. We surveyed genetic variation at 11 microsatellite loci mitochondrial (mt) DNA samples from twelve locations Sea Japan to Washington State. Both (mean H = 0.868) mtDNA haplotype h 0.958) diversities were large did not show any geographical trends. Genetic differentiation between was significantly correlated with distance for both microsatellites (FST 0.028,...
Phylogenetic relationships of snailfishes the family Liparidae were analyzed on basis two sets molecular sequence data: one from mitochondrial DNA cytochrome c oxidase subunit gene (COI) and another restriction-site associated genome-wide sequences (RADseq). The analysis COI data at least 122 species 18 genera Pacific, Atlantic, Southern oceans resulted in a moderately well-resolved phylogeny among major clades, albeit with significant polytomy central clades. Nectoliparis was sister all...
Three major mitochondrial DNA (mtDNA) haplogroups were identified in 5 data sets for North Pacific and Bering Sea walleye pollock. The common haplogroup A showed mirror-image clines on both sides of the with high frequencies southern areas (P(A) > 0.84) low < 0.36). Two additional complimentary, but weaker, opposite direction. These are unlikely to have arisen by chance during postglacial colonizations coastal waters Sea, they do not appear reflect isolation distance. Contrary these trends,...

Abstract Delineating a threshold migration rate for demographic independence important understanding connectivity among fragmented populations and defining management units conservation harvest regulation. In turn, is an essential step in sustainable to avoid unintentional depletion of resources managed or harvest.

Abstract Landscape genetics of Pacific cod Gadus macrocephalus within the Bering Sea and Aleutian Islands (BSAI) management area Alaska was examined in samples from nine spawning locations, including one temporal replicate sample, using 17 microsatellite DNA markers. This study fine‐scale population structure BSAI with goal identifying breaks genetic continuity associated physical barriers to migration larval transport. Samples were taken fish collected western east Unimak Pass as far north...
Information on genetic population structure has been documented in many marine fish species, but it is not always incorporated into management plans. This study examines how conservation status and yield change when units are established using data versus treating the entire area as a single unit. Simulations use spatially structured, individual-based model that combines multilocus microsatellite genotypes traditional dynamics establishes abundance-at-age by cohort. Results considered terms...
There is no established management protocol for stocks subject to isolation-by-distance (IBD) stock structure. This study examines several strategies two marine fish species IBD using simulation: Pacific cod (Gadus macrocephalus) in the Aleutian Islands (AI) and northern rockfish (Sebastes polyspinis) Eastern Bering Sea (EBS) AI. A one-dimensional stepping stone model was used intended mimic regions where are exploited along a continental shelf. The performance of spatial assessment methods...
Over the past two decades, numerous ecosystem surveys and process studies have emerged to monitor assess large marine ecosystems of Alaska. Several regional collaborative integrated research projects (IERPs) were conducted gain understanding fish population fluctuations in relation surrounding environment. The Gulf Alaska (GOA) IERP is one example such an effort. Products this program include a suite situ observations from fully surveys, laboratory experiments physical thresholds for...

Snailfishes of the genus Careproctus deposit egg masses inside gill cavity lithodid crabs. Previous attempts to identify species depositing eggs have been inconclusive because difficulties in identifying snailfish and larvae. For this study, samples were collected from found crabs commercial fishery during benthic trawl survey work. Egg Lithodes aequispinus (Golden King Crab) and, for first time, L. couesi (Scarlet Crab). Mitochondrial DNA cytochrome c oxidase subunit I (COI) region was...
