Whole-genome data has become significantly more accessible over the last two decades. This can largely be attributed to both reduced sequencing costs and imputation models which make it possible obtain nearly whole-genome from less expensive genotyping methods, such as microarray chips. Although there are many different approaches imputation, Hidden Markov Model (HMM) remains most widely used. In this study, we compared latest versions of popular HMM-based tools for phasing imputation:...

Little is known about intraspecific variation within the deacon rockfish (Sebastes diaconus), a recently described species found in northeast Pacific Ocean. We investigated population structure among fish sampled from two nearshore reefs (Siletz Reef and Seal Rock) one offshore site (Stonewall Bank) <50-km2 area off Oregon coast. Fish three sample sites exhibited small but statistically significant differences based on genetic at >15,000 neutral loci, whether analyzed independently or...

Abstract The Alligator Gar Atractosteus spatula has become a focal species of management and conservation due to declining populations growing popularity among anglers. is sympatric with the Longnose Lepisosteus osseus Spotted L. oculatus throughout much its range, providing potential for hybridization that can complicate efforts. Hybridization between gars been documented in captivity; however, natural (i.e., wild) not formally assessed. Population sampling genetic analyses Gars Texas...

Abstract Genetic methods can guide and improve the management of recreational mixed‐stock fisheries by informing stock‐specific estimates harvest. We applied genetic stock identification parentage‐based tagging to a Chinook Salmon Oncorhynchus tshawytscha fishery in Columbia River illustrate value analysis management. sampled landed catch 2017 2018, assigned fish reporting groups, explored temporal trends harvest composition within between seasons, assessed accuracy precision against from...

Abstract Grass Carp Ctenopharyngodon idella stocking in the upper Colorado River basin is statutorily limited to triploid, i.e., functionally sterile, individuals. Systematic fish sampling indicates adult remain rare but have been increasing abundance since 2007. larvae collected arm of Lake Powell, about 26 km downstream from inflow, 2015 and 2016, are evidence presence a spawning population. These were first documentation river western United States. While reproductive biology suggests...

Abstract We examined methods for detecting environmental DNA of the invasive white river crayfish Procambarus zonangulus. In a laboratory experiment, we investigated detection capability in benthic sediment samples and water six flow-through tanks. Additionally determined whether density (low = 0.67 or high 2.69 crayfish·m-2) time tanks influenced detectability (collection on Days 2, 5, 8 15). Species-specific primers probes were designed P. zonangulus their specificity was tested against...

Due to recent population declines in tropical gar (Atractosteus tropicus), a greater understanding of its structure is needed. A key step gaining this the development microsatellite loci for use species. For purpose, 33 from alligator (A. spatula) were screened 52 individuals Zanjón del Chino, El Salvador. Twenty-five these successfully amplified species, and 9 those polymorphic population. These should provide useful tool genotyping A. tropicus, both studying existing wild populations...

Abstract Background Polygenic risk scores (PRS) have ushered in a new era genetic epidemiology, offering insights into individual predispositions to wide range of diseases. However, despite recent marked enhancements their predictive power, there are still challenges that need be overcome before PRS-based models can broadly applied the clinic, including sufficient accuracy, easy interpretability and portability across diverse populations. Methods Leveraging trans-ancestry genome-wide...

Abstract In an increasingly diverse world, including admixed individuals in genomic studies is imperative for equity and portability. A crucial first step precise local ancestry inference (LAI). We have developed Orchestra, a LAI model with unprecedented accuracy, trained on over 10,000 single-origin from 35 worldwide populations. employed Orchestra to delve into genetic relationships demographic histories, focus Latin Americans, prime example of admixture, the Ashkenazi Jewish, whose...

Abstract Genotype imputation, crucial in genomics research, often faces accuracy limitations, notably for rarer variants. Leveraging data from the 1000 Genomes Project, TOPMed and UK Biobank, we demonstrate that Selphi, our novel imputation method, significantly outperforms Beagle5.4, Minimac4 IMPUTE5 across various metrics (12.5%-26.5% as measured by error count) allele frequencies (13.0%-27.1% low-frequency variants).This improvement boosts variant discovery GWAS improves polygenic risk scores.

Clicks collected from an echolocating bottlenose dolphin completing a search task were compared in order to determine if the clicks produced when was acquiring target differed searching for target. The by free-swimming recorded using biosonar measurement tool (BMT), instrumentation package carried that both outgoing and returning echoes. A discriminant function analysis classified as or acquisition variables of peak-to-peak amplitude, duration, peak frequency, center bandwidth. more...
