Environmental gradients decouple demographic and adaptive connectivity in a highly mobile coastal marine species

The paper uses seascape genomics to show that environmental gradients reduce adaptive connectivity in snapper despite high overall gene flow, suggesting contingent migration influences local adaptation.

Selective breeding and production strategies to support snapper farming in the warming waters of New Zealand's South Island

This study evaluates the performance of selectively bred F4 versus unselected F1 Australasian snapper in two rearing environments, finding improved growth and survival in F4 snapper.

Hybridization outcomes reflect context-dependent reproductive isolation in two damselfly hybrid zones

The paper compares reproductive isolation and hybridization patterns in two damselfly hybrid zones, finding context-dependent differences in prezygotic barriers and genomic introgression.

Biofouling on aquaculture mesh: disentangling seasonal and environmental effects with eDNA

The paper examines seasonal and spatial patterns of biofouling on aquaculture mesh using eDNA metabarcoding, revealing environmental drivers and non-native species dominance.

Parallel clines of chromosomal inversion in seaweed flies associated with thermal variation

The paper investigates the role of a chromosomal inversion in seaweed flies, finding it associated with thermal adaptation but not cold tolerance, and highlights its potential for parallel adaptation across continents.

Predicting phenotypes with one step genetic decision trees

The paper uses computer vision and machine learning to predict growth traits in snapper, finding that models capture 18-40% of genetic variation but face challenges from population structure.

Estimation of effective population size and effective number of breeders in an abundant and heavily exploited marine teleost

The paper estimates effective population size (Ne) and effective number of breeders (Nb) for snapper using SNP data and bias correction methods, showing that single-cohort samples yield more reliable results.

A multiplexed plant-animal SNP array for selective breeding and species conservation applications

This paper evaluates a multiplexed plant-animal SNP array for diverse applications, showing high SNP performance across species and cost savings through pooling.

Bioregional boundaries and genomically-delineated stocks in snapper (Chrysophrys auratus) from southeastern Australia

This study uses population genomics to identify bioregional boundaries and genomically-delineated stocks in snapper across southeastern Australia.

Genome assembly and isoform analysis of a highly heterozygous New Zealand fisheries species, the tarakihi (Nemadactylus macropterus)

The paper presents the first genome assembly and isoform analysis of the tarakihi fish, providing a resource for population genomics and comparative studies.

Comparative genomics of tarakihi (Nemadactylus macropterus) and five New Zealand fish species: assembly contiguity affects the identification of genic features but not transposable elements

Fisheries genomics of snapper (Chrysophrys auratus) along the western Australian coast

This study uses population genomics to assess snapper connectivity and structure along the Western Australian coast, finding low genetic differentiation but strong isolation by distance and temporal instability.

Genomic stock structure of the marine teleost tarakihi (Nemadactylus macropterus) provides evidence of fine-scale adaptation and a temperature-associated cline amid panmixia

This study uses whole-genome resequencing to analyze tarakihi populations, finding weak genetic differentiation and a temperature-associated genomic cline despite panmixia.

Genomic prediction of growth in a commercially, recreationally, and culturally important marine resource, the Australian snapper (Chrysophrys auratus)

The paper identifies growth-related genetic variation in Australian snapper using genome-wide association and reduced genome representation data, revealing a polygenic architecture with high heritability.

Unravelling the complex genetic basis of growth in New Zealand silver trevally (Pseudocaranx georgianus)

This study identifies genetic loci associated with growth traits in New Zealand silver trevally using QTL mapping and GWAS, revealing 10 genetic hotspots and demonstrating the utility of combining these approaches.

The genome of New Zealand trevally (Carangidae: Pseudocaranx georgianus) uncovers a XY sex determination locus

The paper reports the genome of New Zealand trevally, identifies a XY sex determination locus, and finds a likely role for the cyp19b-like gene in sex determination.

A metagenomic analysis of the wrackbed microbiome indicates a phylogeographic break along the North Sea - Baltic Sea transition zone

The paper analyzes the microbiome of wrackbeds and seaweed flies along the North Sea-Baltic Sea transition, finding shifts in microbial communities and functionality linked to polysaccharide degradation.

Inversion frequencies and phenotypic effects are modulated by the environment

The paper shows that environmental factors influence the frequency of a genetic inversion and its phenotypic effects on body size in the seaweed fly Coelopa frigida.
