The Sockeye Salmon, also known as the Kokanee Salmon, is a species in the Salmonidae family. Male kokanee from the upper Columbia River drainage were sdY-negative (personal communication DS and RHD), which is consistent with the resequencing data aligned to the sdY sequence. Becker RA, Wilks AR, Brownrigg R, Minka TP, Deckmyn A. maps: Draw Geographical Maps [Internet]. Multiple pathogens are influenced by temperature and several outbreaks in fish farms have been related to temperature (reviewed in [111]). Table 1: confusing and badly formatted. Can. Without the industry and the First Nations, and DFO [representatives] coming together, that funding wouldnt have been approved, said Sieber. In either case, the distance of the hsps (one spanning or two flanking) from the gap was only allowed to be 100 bp, the size of the sequence filling the gap was only allowed to be 100x larger than the predicted gap (the prediction was made in the ALLPATHS-LG assembly from mate-pair data), and the minimum gap size to fill was 9 bp. Typically for the species, sockeye spend their early growth period in a lake, often hatching in a stream that drains down into the lake. off-target or repetitive elements) using the scripts from Christensen et al. One of the main differences of this group and the two others was an apparent change in sex-determination (discussed below). Argue, A.W. We found from demographic data that the sockeye salmon species is not presently at risk of extinction. 1994). 1997). Changed loci to locus in two locations in the manuscript. The French common name is saumon rouge. Fish. Mr. Schweigert is Scientist Emeritus with Fisheries and Oceans Canada at the Pacific Biological Station (PBS), Nanaimo, British Columbia. Fraser River stock composition sampling by the Pacific Salmon Commission found one Sakinaw Sockeye in southern Queen Charlotte Strait (Statistical Area 12) on July 12 in 2010. Several surveys of genetic variation in allozymes (Wood et al. To increase the contig lengths, a custom pipeline was used to fill gaps in the scaffolds. Sockeye salmon (Oncorhynchus nerka) smolt production from Sakinaw Lake, Sechelt Peninsula, BC. shore-spawning vs. stream-spawning) was the leucine-rich repeat-containing 9 gene [17,20,21,24]. Rep. 3 No. If they'll be preparing press materials, please inform our press team within the next 48 hours. We continue with part four of our series 'Returning home: The Elwha's genetic legacy.'.

Beach 2 was no longer being used, and the suitable habitat there is estimated at about 25% of that available in 1979 (1500 versus 6000 m2). The Sockeye Salmon, Oncorhynchus nerka. Fish. The assembly already had an accession as well, but we added the NCBI BioProject ID so all 170 SRA accessions can be identified (e.g. Mechanisms controlling migration of sockeye salmon fry. Dive surveys in 1999 and 2000 indicate that the Sockeye were using only 15% of the area of Beach 1 (900 versus 6,000 m2). Where one grouping ends and the other begins was inconsistent among studies and likely reflects the latitudinal cline seen in the admixture analysis of the current study as well as variation in which specific locations were included in each study. Are there extreme fluctuations in extent of occurrence? The sdY gene arose from a gene duplication of an immune-related gene that diverged to be able to interact with the Forkhead box domain of the female-determining transcription factor and eventually disrupt female differentiation [149]. 2011. The sediment traps were built at the top of S-2 and S-3, where gravel and woody debris would be held and emptied. Sockeye salmon (Oncorhynchus nerka) is a commercially and culturally important species to the people that live along the northern Pacific Ocean coast. Pacific fishes of Canada. To generate the truth sets, sequences and SNP positions were manually extracted from supplemental files and converted to 1-based positions (instead of 0-based), and mapped to the genome with bwa mem (these SNPs previously did not have genomic positions, but positions relative to a sequenced read). Babraham BioinformaticsFastQC A Quality Control tool for High Throughput Sequence Data. The perimeter of Sakinaw Lake is a mixture of Crown Land and Private Land holdings. University of New Brunswick, Biological Sciences, Saint John, New Brunswick, Canada, 5 July, 2015. What about the gene duplication between chr21 and chr26 are these homeologous in sockeye? only adaptors were removed based on review of the output from FastQC). On the right, LD plot of chromosome 9b from 3.5 Mbp to 11.5 Mbp. COSEWIC assessment and status report on the sockeye salmon Oncorhynchus nerka (Cultus population) in Canada. Henry, K.A. 2002. The woody debris collected at the confluence between S-1 and S-2, interrupting the water flow in the two streams, he said. Are there extreme fluctuations in index of area of occupancy? They are endemic to Canada and share marine migration corridors and foraging habitat in the North Pacific Ocean with many other Sockeye Salmon populations. DFO. Additionally the Sechelt First Nation has a Reserve at the outlet of the lake with a vested interest in preserving the habitat. Funding for this study was provided by Fisheries and Oceans Canada (https://www.dfo-mpo.gc.ca/index-eng.htm) under the Canadian Regulatory System for Biotechnology to RHD. In Figure 2B, this figure was used in Figure 3, 4, 5 and 6. DAPC group 3 included all populations either north or west of the Babine River in central British Columbia. A) On the left of this figure is the admixture ancestry plot with the DAPC group assignments. The manuscript must describe a technically sound piece of scientific research with data that supports the conclusions. It clearly shows that the number of mature individuals declined by 100% during this time period; a statistical analysis is not required. Allele balance is the ratio between alleles. 1(2): 207-221. Fish. The authors have addressed all of my comments and I feel the manuscript is now suitably for publication albeit with a couple of small changes. Thermal limits and ocean migrations of sockeye salmon (Oncorhynchus nerka): long-term consequences of global warming. 1961. Koren S, Walenz BP, Berlin K, Miller JR, Bergman NH, Phillippy AM. Low water flow and high water temperature can impact migration into Sakinaw Lake, and Sockeye Salmon enter the fishway only on the higher tides at night. Intern. You will not receive a reply.

And it was important that we made sure that the sockeye run was going to be there for COSEWIC assessment and status report on the Sockeye Salmon Oncorhynchus nerka, Sakinaw population,in Canada. Intern. Small adult size results in both low fecundity and small egg size. In 1986, logging in the upper reaches of a stream leading to Cheewaht Lake started, affecting S-2 (Stream 2), one of the three streams that feed the lake, he said. 2018 [24,143]). Small populations of Coho and Chum (O. keta) salmon also occur in Sakinaw Lake and may compete with Sakinaw Sockeye for spawning habitat. 2104). In the ocean, Sockeye Salmon typically inhabit cool (2-7C) surface waters (less than 15 m) and those from BC generally remain north of 48N latitude and east of 160W longitude (French et al. Therefore, Sakinaw Sockeye has a significant role in the ecology of the Sakinaw Lake ecosystem. 2019 [cited 2020 Feb 21]. In prehistoric times, the lake flowing into the Elwha was much larger, according to geologists who say that todays Lake Crescent and Lake Sutherland were once a single lake. Parks Canada received a letter from Ditidaht nation urging it to address restoration in the creek, said Yuri Zharikov, an ecologist for Pacific Rim National Park Reserve. This type of run can be large enough to catch tens of millions of fish in good years. In order to tell what is specifically different between groups, only two groups could be compared at a time. 2005. Any typographical or grammatical errors should be corrected at revision, so please note any specific errors here. Soc. In Washington, sockeye are found in Lake Washington, Baker Lake, Ozette Lake, Quinault Lake, and Lake Wenatchee. In summer, the epilimnion extends to 7 m depth and becomes too warm for Sockeye, but between 7 m and 30 m there is cool, well-oxygenated habitat that is rich in zooplankton and very suitable for rearing juvenile Sockeye (Shortreed et al. Except for haplotype #1, none of the haplotypes observed in the donor lake systems (#1, 2, 3, 4 and 6) were observed in Sakinaw Lake. Every system transports sediment and gravel, but problems occur when the system is out of balance, said Abbott. 9: 265-306. By all accounts, that native migratory population of Oncorhynchcus nerka died out soon after the Elwha Dam blocked the upstream passage of these red-bodied fish with green heads. The way I read it the kokanee appear to be monophyletic with respect to multiple rivers from the same area. Internat. comparing sockeye salmon and kokanee) (Table 3). Thus, stocking Sakinaw Lake with Cutthroat Trout may have decreased the survival of juvenile Sockeye in Sakinaw Lake. Poor survival in the ocean and fishing mortality remain the two significant threats. The study found that only five of those fish had a strong genetic link to the Stikine River, so it is unlikely that strays from that distant population were visiting the Elwha. Godmann M, Katz JP, Guillou F, Simoni M, Kaestner KH, Behr R. Krppel-like factor 4 is involved in functional differentiation of testicular Sertoli cells. All raw sequences had already been submitted to NCBIs SRA. [Observed, estimated, inferred, or suspected] percent [reduction or increase] in total number of mature individuals over the last [10 years, or 3 generations]. Can. The Sakinaw Sockeye Salmon population existed in this single location within Sakinaw Lake prior to its extirpation between 2006 and 2009. Recent surveys of the spawning beaches indicate that only beach 1 (Sharons) continues to be in regular use (Sakinaw Sockeye Recovery Team 2013). The sacrospan gene, another candidate gene, associates with the sarcoglycan subcomplex [138]. Rep. Nr. These libraries were sequenced on an Illumina HiSeq 2500 (PE125). Read online free Sockeye Salmon Oncorhynchus Nerka Population Biology And Future Management ebook anywhere anytime directly on your device. Sakinaw Sockeye may have evolved the size and return timing in response to Sakinaw Lakes unique location and hydrology with short migration and access only during specific water flow conditions. (2006, unpublished data) for 2004 and 2005 using similar methodology and assumptions about the shape of the run timing curve and using daily fence counts and daily harvest rate data to reconstruct the run size. All fastq files were recieved as single files (per individual) from McGill University and Gnome Qubec Innovation Centre. A review of Lake Washington sockeye (Oncorhynchus nerka) age and racial characteristics as determined by scale analysis. Are these principle components 1 and 2? Variants in the VCF file were filtered using the GATK command VariantFiltration (filterExpression QD < 2.0 || FS > 60.0 || SOR < 3.0 || MQRankSum < -12.5 || ReadPosRankSum < -8.0). The New Directions Policy stimulated development of a Wild Salmon Policy (DFO 2005) to promote the long-term viability of Pacific salmon populations and their natural habitat. Lines 84-85: replace that population structure with ecotype divergence. The associations of the sdY presence/absence analysis but not phenotypic sex reached significance after Bonferroni correction ( = 0.01). De Tomasi L, David P, Humbert C, Silbermann F, Arrondel C, Tores F, et al. However, its difficult to interpret the figure and make the link between the data and how they support the hypothesis of an inversion. Its so culturally important as a food resource.. Resequenced whole-genomes of 140 sockeye salmon and kokanee were analyzed to understand population structure and identify genomic differences between ecotypes. Why the protein-coding genes annotated in this species were much less than salmon and trout? Both analyses began with the same 124,663 variants already filtered for common factors (e.g. Burkett. Please log into your account, locate the manuscript record, and check for the action link "View Attachments". 10: 134p. Specifically, I would like to see more information on how the authors dealt with the homeologous regions of the sockeye genome. Sci. Essentiality of Regulator of G Protein Signaling 6 and Oxidized Ca2+/CalmodulinDependent Protein Kinase II in Notch Signaling and Cardiovascular Development, J Am Heart Assoc Cardiovasc Cerebrovasc Dis. We have added a goal statement in the abstract to try to give the reader a better sense of the focus and goals. 1962. Line 716: I thought the inclusion of the double haploid in the runs of homozygosity analysis was unnecessary. For the admixture analysis, chromosome names were changed in the vcf file using a custom script (S1 File), and the vcf file was converted to an appropriate format using PLINK v1.9 [83,84] (parameters:double-id,chr-set 29 no-xy). 1997, Withler et al. Despite numerous stocking attempts, establishment of self-perpetuating Sockeye Salmon runs have been documented only in three locations: 1) Lake Washington (Royal and Seymour 1940, Kolb 1971), 2) Frazer Lake, Kodiak Island (Blackett 1979), and 3) Upper Adams River in the Fraser River system (Williams 1987). Your manuscript will remain under strict press embargo until 2 pm Eastern Time on the date of publication. Added that this was multiple variants, and the approximate region and candidate gene. NOAA. undefined. 1978. From trumpeter swans to black bears, the Cheewaht Lake watershed provides a home for dense and rare biodiversity. (ed.) In the lake they are vulnerable to predation, especially by a non-anadromous parasitic lamprey (probably L. tridentata). Size selection was performed on the libraries using a 0.5% agarose gel for the following sizes: 3, 5, 10 kbp. In 2017, the Cheewaht Restoration Working Group was re-established to collaborate on ways to restore salmon spawning streams in the Cheewaht Lake that had been affected by logging. Pacific Salmon Fish. We note that you are reporting an analysis of a microarray, next-generation sequencing, or deep sequencing data set. The percent of repetitive elements was identified in genomic blocks from the modified genomic fasta file and the Percent_Repeat_Genome_Fasta.py script [57]. Id suggest re-writing this section perhaps to emphasize that whats interesting here is the discrepancy in the normal dogma that sympatric kokanee and sockeye are more closely related to each other than either is to allopatric populations of the same ecotype. Admixture plots were created in R using the ggplot2 and reshape2 [85] libraries. Mar. If your institution or institutions have a press office, please let them know about your upcoming paper now to help maximize its impact. First the raw paired-end reads were aligned to the genome with bwa mem (-M parameter) version 0.7.17 [73], and Samtools sort version 1.9 was used to sort the resulting alignments. Supernault. Peterman, R.M. This will be checked in preparation for publication. This is discussed in the text and includes alternative mechanisms. We note that you are reporting an analysis of a microarray, next-generation sequencing, or deep sequencing data set. In lower-quality genome assemblies, these regions are typically left as contigs because there is not enough information to put them in the correct place on chromosomes. Adult Sockeye have a slender, streamlined, silvery body with faint blue-green specking on the back with silver sides fading to white below. [Projected or suspected] percent [reduction or increase] in total number of mature individuals over the next [10 years, or 3 generations]. 21: 1321-1324. The goal of the recovery plan was to stop the decline of the Sakinaw Lake Sockeye Salmon population and re-establish a self-sustaining, naturally spawning population, ensuring the preservation of the unique biological characteristics of this population. Between 2000 and 2018, the total 1967. How are the authors determining this? Can. Ware, and R.M. To comply with PLOS ONE submissions requirements, please provide methods of sacrifice in the Methods section of your manuscript. In this case 0.05 / total number of SNPs (450868) should give a negative log10 P value of 6.955. Variants of the Mtr4 exosome RNA helicase might influence infectivity of viruses, and the divergence at this locus may reflect different pathogenic environments and local adaptation of the upper Columbia River kokanee. Connors (2011) did note that the survival of Fraser Sockeye Salmon was reduced when farm fish production was high, sea surface temperature in the Pacific Ocean was reduced, and Pink Salmon abundance was high. Restoration managers are hopeful thatpopulations of coho, chum and pink salmon will rebound on the Elwha River as the fish take advantage of newly accessible habitat. E) On the left, LD plot of chromosome 9a from 4.6 Mbp to the end of the chromosome (~2 Mbp) with a minimum LD threshold of r2 = 0.5 for both plots. Can. RNA-seq libraries (see above) of red muscle (SRA accession: SRX5621463), hind gut (SRX5621462), stomach (SRX5621461), ovaries (SRX5621460), gill (SRX5621459), spleen (SRX5621458), pituitary (SRX5621457), white muscle (SRX5621456), pyloric caeca (SRX5621455), adipose (SRX5621454), heart (SRX5621453), liver (SRX5621452), brain (SRX5621451), mid gut (SRX5621450), left eye (SRX5621449), upper jaw (SRX5621448), head kidney (SRX5621447), and lower jaw (SRX5621446) were submitted to GenBank to improve the NCBI genome annotation. McKenna A, Hanna M, Banks E, Sivachenko A, Cibulskis K, Kernytsky A, et al. Scientific name: Oncorhynchus nerka. 162:4 22 p. Francis, R.C. Ten loci were associated with the kokanee ecotype (i.e. Interestingly, dipeptidyl-peptidase 6 has previously been found as an outlier locus between a northern and southern snail population in which the author suggested that divergence could be a result of thermally-driven selection [123]. Or between beach and stream spawning? The RNA Exosome Syncs IAV-RNAPII Transcription to Promote Viral Ribogenesis and Infectivity. Anecdotal reports of escapement date back to 1933 but routine assessments began in 1947 and are reported in the DFO annual spawning escapement surveys (BC 16s) and are available in the Salmon Escapement Data System (SEDS) database (Murray and Wood 2002). Window counts between 100999 are green, while those with counts greater than 999 are orange. There were nine peaks identified from the eigenGWA comparing the Fraser River sockeye salmon and kokanee (Table 2, S5 Fig). The Snake River sockeye salmon was listed as endangered in November 1991, after the Shoshone-Bannock Tribe at Fort Hall I Simo FA, Waterhouse RM, Ioannidis P, Kriventseva EV, Zdobnov EM. The two remaining clusters are congruent with previous studies, which also found a northwestern and southern grouping [8,9]. 2013 Mar 16 [cited 2017 Dec 19]; Danecek P, Auton A, Abecasis G, Albers CA, Banks E, DePristo MA, et al. 2006. In co-ordination with Parks Canada, Ditidahts stewardship and monitoring program will continue to check on the restored streams and surrounding ecosystems, monitoring things like rainfall, water quality, stream levels and invertebrates. There is some concern regarding the consistency in methodology over the years. Sockeye salmon can be anadromous (ocean-going) or remain as freshwater populations known as kokanee . DePristo MA, Banks E, Poplin R, Garimella KV, Maguire JR, Hartl C, et al. Doc. Finally, the sex chromosomes of this species were better characterized, and an alternative sex-determination mechanism was identified in a subset of upper Columbia River kokanee. Added that chr21 and chr26 are homeologous. The chart shows annual escapement (symbols) and four-year average (trend line). Kraft, 20 November 1975. D) IGV was used to visualize variants on chromosome 9a with only minimal filtering for known females (no upper Columbia River kokanee), males (no upper Columbia River kokanee), Freshwater Fisheries Society of British Columbia female kokanee, and Freshwater Fisheries Society of British Columbia male kokanee. Run-timing data was not collected for this study but should be examined in future investigations now that this association has been identified in sockeye salmon. 4. We increased the threshold from 3 nearby variants required to be considered a real peak to 5 to only analyze the most robust results. Overlapping paired-end library preparation and sequencing (used for genome assembly) was performed at McGill University and Gnome Qubec Innovation Centre. For example, in addition to summary statistics, the data points behind means, medians and variance measures should be available. COSEWIC comprises members from each provincial and territorial government wildlife agency, four federal entities (Canadian Wildlife Service, Parks Canada Agency, Department of Fisheries and Oceans, and the Federal Biodiversity Information Partnership, chaired by the Canadian Museum of Nature), three non-government science members and the co-chairs of the species specialist subcommittees and the Aboriginal Traditional Knowledge subcommittee. B) A GWA between all individuals scored for the presence or absence of the sex-determining gene (red line indicates significance threshold). 2002a,b). 1997, Nelson et al. There were no significant associations from a GWA of the sex phenotype with any markers, but there was a ~100 kbp peak at the krppel-like factor 5 gene (LG1 6,248,5076,256,452 bp). Although Sakinaw Lake lies at an elevation of only 5 m, access to and from the lake can be difficult for Sockeye Salmon during periods of low water flow (COSEWIC 2002). An immunoglobulin heavy chain variable gene cluster on chr. however, I have many concerns both with regard to the writing and clarity of the manuscript as well as the analyses chosen. P. 33-43 In: K.T. Freshwater fishes of northwestern Canada and Alaska. The most serious habitat degradation was evident prior to the first diver survey in 1979, but impacts have continued. An experimental study of competition for food between sockeye salmon (Oncorhynchus nerka) and threespine stickleback (Gasterosteus aculeatus) in a British Columbia coastal lake. However, we have reduced this discussion and it is only briefly mentioned now with most of the results and discussion removed. In summary, the captive-breeding program is a manipulated population established to preserve the species and therefore it should be considered part of the wildlife species (Guideline #2). Bertho S, Herpin A, Branthonne A, Jouanno E, Yano A, Nicol B, et al. For regions of interest found from an eigenGWA analysis, the variant with the lowest p-value was used to identify all the markers in that region in LD (minimum r2 of 0.3) using VCFtools. COSEWIC Committee on the Status of Endangered Wildlife in Canada, COSEPAC Comit sur la situation des espces en pril au Canada. Like salmon, the culturally and ecologically important fish also move from saltwater into rivers to spawn. FOIA So far, biologists have not even established whether Olympic Peninsula streams contain identifiable and sustainable populations of riverine sockeye, Crain said. Fish. Talin 2 is a large and complex gene encoding multiple transcripts and protein isoforms. 1991. This requires assignment of orthologs between species first. 2015. Approximately 380,000 fry were transplanted into Sakinaw Lake from the various donor stocks (Aro 1979). After careful consideration, we feel that it has merit but does not fully meet PLOS ONEs publication criteria as it currently stands. This divergence between the two other groups is likely driven by isolation of this group from the other two for possibly up to 10,000 years. It changed the results and discussion quite a bit. This first filter removed variants that were not biallelic, indels, had missing data in more than 10% of the individuals, that were marked as failed by GATK, or if the minor allele frequency was below 0.05. An error was found in this figure, with the DAPC groups mixed up on the DAPC figure. sharing sensitive information, make sure youre on a federal Kept on biological life-support for more than two decades, Idahos iconic sockeye salmon are making a comeback. The dark blue colour represents homozygous reference variants (HomRef), the green colour represents homozygous alternative variants (HomVar), and the light blue colour represents heterozygous variants (Het). Are there other datasets that might point towards an inversion on chr24, or is this completely novel? (2016) are shown in blue below the genetic map. This peak encompassed the markers with the lowest p-values with the sex phenotype. Larson WA, McKinney GJ, Limborg MT, Everett MV, Seeb LW, Seeb JE. Subsequently, maturing adults returned to the lake from the ocean to spawn from 2010 through 2014 (range 29 to 555) as a result of fry releases into the lake (Table 3) from the captive breeding program (Withler et al. For part C, we were trying to show haploblocks and this is better explained in the manuscript now and shown in better detail in the figure. Eggs and alevins remain buried in gravel during the winter. is >50% of its total area of occupancy in habitat patches that are. During recovery planning before dam removal, some experts expressed hope that the Lake Sutherland kokanee might become migratory and begin a new run of sockeye. Internat. Smolts from coastal populations are typically smaller and younger (implying a lower smolt size threshold) than interior lakes of comparable productivity making Sakinaw Sockeye atypical of coastal populations. Gnerre S, MacCallum I, Przybylski D, Ribeiro FJ, Burton JN, Walker BJ, et al. 1999). 1997, Mueter et al. Int. The overall intensity of mixed-stock fishing in Johnstone and Georgia straits generally increased until the late 1990s in response to high abundance and high diversion rates of Fraser River Sockeye Salmon through Johnstone Strait. Waples. The captive breeding program that exists to maintain and rebuild the population is located at the hatchery at Rosewall Creek on Vancouver Island and is maintained by DFO. It has two distinct basins separated at Beach 1 (Figure 3). 2014. Learn more The threshold lines were redrawn with the correct values. Tech. Parks Canada has continued to monitor the area for the immediate results of restoration, he said, counting the active fish and carcasses in and around the streams to determine the lifespan of the salmon in the creek. A Sakinaw Sockeye Salmon Recovery Team was established to develop a recovery plan and many of the recommendations have been implemented. Dill, L.M. Talin 2 is a large gene with multiple transcript isoforms with tissue specific expression, including a spermatid specific isoform [116]. Protocols.io assigns your protocol its own identifier (DOI) so that it can be cited independently in the future. None of the fish came from the Lake Sutherland population, said Quinn, who led the study published last year in Transactions of the American Fisheries Society. Salmon Fish. Please give the manuscript a thorough re-read before resubmitting. An official website of the United States government. Yasuike M, de Boer J, von Schalburg KR, Cooper GA, McKinnel L, Messmer A, et al. The lower basin is the largest with a maximum depth of 140 m and a mean depth of 43 m. The upper basin is small and shallow with a maximum depth of only 40 m. Both basins are clear with a mean euphotic depth of just over 15 m (Shortreed et al. Line 505: why do the authors think its unclear if cpa6 is the most likely gene under this association peak? The GATK model would likely treat these regions as poorly supported and call fewer variants in them. Fishing effort is regulated based on test-fishing indices of the abundance of large Fraser River Sockeye populations. There were many more associations when considering the lower threshold. Two peaks were observed for phenotypic sex (chromosomes 9a and 9b) and the sex-determining gene presence/absence GWAs (Fig 5). Rondeau EB, Minkley DR, Leong JS, Messmer AM, Jantzen JR, von Schalburg KR, et al. Instead, we removed sequenced and assembled and added generated in their place. 1994.

Mueter, F.J., R.M. Although the external referees express interest in the general subject area of the paper, they also express a series of reservations that preclude publication of the paper in PLoS ONE in its current form. Second-generation PLINK: rising to the challenge of larger and richer datasets, Interactive Tree Of Life (iTOL) v4: recent updates and new developments. Pacific rim population structure of sockeye salmon as determined from microsatellite analysis. Murray and Wood (2002) inferred the minimum total exploitation rate on Sakinaw Lake Sockeye for the periods 1986-89 and 1992-94 using two methods. Were pleased to inform you that your manuscript has been judged scientifically suitable for publication and will be formally accepted for publication once it meets all outstanding technical requirements. Several studies have previously identified genomic regions underlying the various sockeye ecotypes (including spawning habitat ecotypes not discussed earlier) [1723]. Line 169-170: I dont understand the and using paired-end data add on. This really confused me and Id request that the authors move the figure legends to before the figures rather than embedding them in the results section. Please indicated it in the introduction. It is involved in many biological pathways from cardiovascular development to alcohol dependence in mammals [118,119].

In the previous section, it was said that there were three grouping methods, DAPC, admixture, and a phylogenetic tree. The heterozygotes/kbp statistic can vary depending on coverage and other factors that were not controlled for. They were then sequenced on an Illumina HiSeq X (PE150) after libraries passed QC (Quant-iT PicoGreen dsDNA Assay Kit, Kapa Illumina GA with Revised Primers-SYBR Fast Universal Kit (Kapa Biosystems), and LabChip Gx (PerkinElmer)). Tabix: fast retrieval of sequence features from generic TAB-delimited files. In the 1880s an estimated 25,000 and 35,000 sockeye would return annually Custom scripts and sample information can be found in supplemental files. Marey maps (graphs with genetic map positions on one axis and genomic positions on the other axis) were generated for each of the previously published sockeye salmon genetic maps [32,62,63] using the methodology from Christensen et al. Rearing The goal of this study was to better understand the population structure of sockeye salmon and identify possible genomic differences among populations and between the two ecotypes. Aro, K.V. Added discussion of why these genes might be connected to ecotype. Trans. Estimates considered unrepresentative (DFO 2015), not used in determination of trends in abundance. RNA-seq libraries were generated at McGill University and Gnome Qubec Innovation Centre after the RNAs passed QC (NanoDrop Spectrophotometer ND-1000 (NanoDrop Technologies, Inc., and 2100 Bioanalyzer (Agilent Technologies)). Changed with a slight modification to let the reader know that we looked at divergence between populations and ecotype. The blue line is for = 0.05. Potential predators of juvenile Sockeye Salmon in or near Sakinaw Lake include Cutthroat Trout (O. clarki), juvenile Coho Salmon (O. kisutch) and Chinook Salmon (O. tshawytscha), Prickly Sculpin (Cottus asper) and Lampreys (Lampetra tridentata and L. ayresi). There are two immunoglobulin heavy chain loci in Atlantic salmon and these duplicated loci likely reflect the salmonid-specific whole-genome duplication [94,109]. separated from other habitat patches by a distance larger than the species can be expected to disperse? Opening the door for coho, chum, and pink salmon, 'Returning home: The Elwha's genetic legacy. Spec. This was made more clear in the manuscript. 1987. Perhaps something like where multiple populations of Kokanee are more closely related to each other than sympatric sockeye salmon. Regulator of G protein signaling 6 is a critical mediator of both reward-related behavioral and pathological responses to alcohol, A New TASK for Dipeptidyl Peptidase-like Protein 6, Dipeptidyl Peptidase-Like Protein 6 Is Required for Normal Electrophysiological Properties of Cerebellar Granule Cells. why wasnt LD filtered? This was done for visualization and not used in any analyses. The Morice Lake sockeye CU is the largest population in the Bulkley watershed, and the Wetsuweten have fished them at this site for 6,000 years. The northern diversion refers to the proportion of returning Fraser Sockeye migrating through Johnstone rather than Juan de Fuca Strait. Salish Sea Chinook salmon populations are down 60% since the Pacific Salmon Commission began tracking salmon abundance in 1984. Line 140: add how large the size selected fragment of DNA was. However, any disease outbreaks at the hatchery or other catastrophic events that destroy the captive brood population would likely render the Sakinaw Sockeye DU extinct. In addition, RNA-seq data were generated to help with annotated the composite genome. The second method reconstructed the probable catch of Sakinaw Lake Sockeye from PSC estimates of the weekly aggregate non-Fraser Sockeye catch. Large size at smolting and an unusual incidence of age 2+ smolts occur despite large size at age 1+. In this study, we generated a reference genome assembly for sockeye salmon, a useful RNA-seq data set for annotation of this and future sockeye salmon genome assemblies, and identified regions of the genome underlying population structure and sockeye salmon ecotype. UBC Press University of British Columbia ,Vancouver BC.. Christensen, V. and A.W. Yes. More systematic dive surveys of the spawning grounds conducted in 1999 through 2002 yielded estimates from 14 (23 redds) to 112 spawners (60 redds). 2018. 1995. NA. Smoltification is critical to ocean-going sockeye salmon as it prepares the parr (developmental stage before smoltification) for the challenges of a marine environment. This population experienced a very large decline in the 1980s and 1990s because of low ocean survival and overfishing. From 1947 to 1987, the estimated number of maturing adults entering Sakinaw Lake averaged about 4,500 individuals (range 750 to 16,000) with no declining trend. I thought Bonferroni significance is determined by dividing alpha by the sample size. Tech. Beacham TD, Jonsen KL, Supernault J, Wetklo M, Deng L, Varnavskaya N. Pacific Rim Population Structure of Chinook Salmon as Determined from Microsatellite Analysis, Population structure of sea-type and lake-type sockeye salmon and kokanee in the Fraser River and Columbia River drainages. This gene is proximal to the six homeobox 6 gene that is a candidate gene under strong selection in differing Atlantic salmon (Salmo salar) populations (associated with upstream catchment) [24]. Journals will often have low quality figures in auto-generated PDFs for review. Mueter, F.J., D.M. Similar to differences between the DAPC groups, a sperm-related gene differentiates sockeye and kokanee ecotypes. The resulting alignment files were filtered with the Compare_Genome_2_Other_Genome_blastfmt6_ver1.0.py (-minl 0.01 -minal 30000) and Filter_Linear_Alignment.v1.0.py (default) Python scripts [60]. DAPC group 2 was composed of fish from multiple drainages on the BC coast and interior and appears to exhibit clinal variation in admixture values from DAPC groups 1 and 3 (Fig 3). 54: 543-554. *Immunoglobulin heavy chain variable gene cluster. The figures are appropriate and clear. I agree with the referee that some minor revisions are still needed. The site is secure.
