Abstract Decision‐makers in inland fisheries management must balance ecologically and socially palatable objectives for ecosystem services within financial or physical constraints. Climate change has transformed the potential range of available. The Resist‐Accept‐Direct (RAD) framework offers a foundation responding to climate‐induced modification; however, trajectories current practices be understood improve future decisions. Using Wisconsin's diverse as case study, strategies recreational...

Native species that persist in urban environments may benefit from local adaptation to novel selection factors. We used double-digest restriction-side associated DNA (RAD) sequencing evaluate shifts genome-wide genetic diversity and investigate the presence of parallel evolution with urban-specific factors wood frogs (Lithobates sylvaticus). Our replicated paired study design involved 12 individuals each 4 rural populations improve our confidence detected signals are indeed urbanization....

Abstract Genomic tools are lacking for invasive and native populations of sea lamprey ( Petromyzon marinus ). Our objective was to discover single nucleotide polymorphism (SNP) loci conduct pedigree analyses quantify reproductive contributions adult lampreys dispersion sibling larval different ages in Great Lakes tributaries. Additional applications data were explored using additional geographically expansive samples. We used restriction site‐associated DNA sequencing (RAD‐Seq) genetic...

Abstract Harvest in walleye Sander vitreus fisheries is size‐selective and could influence phenotypic traits of spawners; however, contributions individual spawners to recruitment are unknown. We used parentage analyses using single nucleotide polymorphisms test whether parental were related the probability offspring survival Escanaba Lake, Wisconsin. From 2017 2020, 1339 adults 1138 juveniles genotyped 66% assigned at least one parent. Logistic regression indicated reproductive success...

Abstract Metapopulation‐structured species can be negatively affected when landscape fragmentation impairs connectivity. We investigated the effects of urbanization on genetic diversity and gene flow for two sympatric amphibian species, spotted salamanders ( Ambystoma maculatum ) wood frogs Lithobates sylvaticus ), across a large (>35,000 km 2 in Maine, USA, containing numerous natural anthropogenic gradients. Isolation‐by‐distance (IBD) patterns differed between species. Spotted showed...

ABSTRACT Many species of reptiles and amphibians (herpetofauna) rely on wetlands that are being degraded lost at a high rate. Characterization herpetofauna diversity in different wetland types may help guide conservation strategies. However, traditional survey methods often involve sampling within small temporal windows, the gear deployed be taxonomically biased, thus, they fail to accurately characterize presence/absence diversity. In contrast, environmental (e)DNA metabarcoding has been...

Abstract Natural rates of straying are difficult to quantify over large spatial scales using direct observations, particularly for long‐lived fish species characterized by delayed sexual maturity and long interspawning intervals. Using multilocus microsatellite genotypes likelihood‐based statistical methods, we quantified immigration emigration six genetically differentiated (mean F ST = 0.041) lake sturgeon Acipenser fulvescens populations in Lake Michigan based on adults ( n 437) captured...

The expansion of shell disease is an emerging threat to the inshore lobster fisheries in northeastern United States. development models improve efficiency and precision existing monitoring programs advocated as important step mitigating its harmful effects. objective this study construct a statistical model that could enhance effort through (1) identification potential disease-associated abiotic biotic factors, (2) estimation spatial variation prevalence fishery. A delta-generalized additive...

This study used analyses of the genetic structure a non-game fish species, mottled sculpin Cottus bairdii to hypothesize probable recolonization routes by cottids and possibly other Laurentian Great Lakes fishes following glacial recession. Based on samples from 16 small streams in five major Lake Michigan, U.S.A., tributary basins, significant interpopulation differentiation was documented (overall FST = 0·235). Differentiation complex, however, with unexpectedly high similarity among...

Information regarding site occupancy of fish that migrate long distances during nonspawning periods together with estimates recruitment trends for individual populations can be informative management, especially when individuals from different spawning intermix and are sampled or harvested together. Tendencies to preferentially occupy specific regions increases vulnerability anthropogenic natural disturbances. Using mixed stock analysis (MSA), we estimated population-specific lake sturgeon...

Linking genotype to phenotype is a primary goal for understanding the genomic underpinnings of evolution. However, little work has explored whether patterns linked and phenotypic differentiation are congruent across natural study systems traits. Here, we investigate such with meta-analysis studies examining population-level at subsets loci traits putatively responding divergent selection. We show that 31 (88 comparisons) examined, there was moderate (

Despite the widespread occurrence of microsporidian parasites in vertebrates and many invertebrates, research regarding their effects on wild populations remains uncommon. We used several metrics individual growth, condition, population characteristics to evaluate a infection (Glugea) six infected mottled sculpin (Cottus bairdii) compared with 10 nearby uninfected populations. Infected individuals (n = 129) were significantly heavier each age class when fish 331), yet other measures growth...

Intraspecific variation in pathogen shedding impacts disease transmission dynamics; therefore, understanding the host factors associated with individual is key to controlling and preventing outbreaks. In this study, ileum bursa of Fabricius tissues wild-bred mallards (Anas platyrhynchos) infected low-pathogenic avian influenza (LPAIV) were evaluated at various post-infection time points determine genetic intraspecific viral shedding. By analysing transcriptome sequencing data (RNA-seq), we...

Understanding patterns of genetic structure and adaptive variation in natural populations is crucial for informing conservation management. Past research using 11 microsatellite loci identified six stocks lake whitefish (

Abstract Most studies that investigate biases in stream fish abundance estimators focus on salmonines, yet nongame species comprise a major portion of assemblages. We evaluated mark–recapture (the Lincoln–Petersen estimator with Chapman correction) and removal (constant capture probability generalized estimators) methods for estimating Mottled Sculpin Cottus bairdii , we tested whether assumptions the (i.e., population is closed during sampling; marks are detected) were reasonable. Over 2‐d...

The blue-winged teal (Spatula discors) is a recreationally and ecologically important dabbling duck species in North America. Transcriptomic data of this can be used public animal health studies given its role as natural reservoir host for avian influenza, which zoonotic disease high concern. Ileum bursa Fabricius tissues were sampled from six captive raised teals, four the who experimentally infected with low-pathogenic influenza virus H5N9. RNAseq generated extracted total mRNA each tissue...

ABSTRACT The establishment and spread of invasive species are directly related to intersexual interactions as dispersal reproductive success distribution, effective population size, growth. Accordingly, populations established by r‐selected particularly difficult suppress or eradicate. One such species, the red swamp crayfish ( Procambarus clarkii ) is globally at considerable ecological financial costs natural human communities. Here, we develop a single nucleotide polymorphism (SNP) loci...
