Environmental Gradients Decouple Demographic and Adaptive Connectivity in a Highly Mobile Coastal Marine SpeciesNARA Subscribed
Understanding how eco‐evolutionary processes shape genetic variation and persistence in marine species with highly variable recruitment dynamics and dispersal potential remains a fundamental challenge, particularly when considering the interplay between gene flow and local adaptation. Here, we employed a seascape genomics approach to investigate population connectivity and local adaptation in Australasian snapper ( Chrysophrys...
Carryover Effects on Reproduction Can Buffer Against Mortality‐Driven Population Declines at Elevated Developmental TemperaturesNARA Subscribed
Carryover effects broadly influence adult performance and population persistence. Although variation in developmental environments can have contrasting effects on survival and reproduction, current predictive models of vulnerability to environmental change typically ignore simultaneous changes in both fitness components. We tested how developmental temperatures shape survival and multiple aspects of reproduction in a plant‐liv...
Common, low-frequency, rare, and ultra-rare coding variants contribute to COVID-19 severityNARA Subscribed
The combined impact of common and rare exonic variants in COVID-19 host genetics is currently insufficiently understood. Here, common and rare variants from whole-exome sequencing data of about 4000 SARS-CoV-2-positive individuals were used to define an interpretable machine-learning model for predicting COVID-19 severity. First, variants were converted into separate sets of Boolean features, depending on the absence or the pr...
Continental‐scale acoustic telemetry and network analysis reveal new insights into stock structureNARA Subscribed
Delineation of population structure (i.e. stocks) is crucial to successfully manage exploited species and to address conservation concerns for threatened species. Fish migration and associated movements are key mechanisms through which discrete populations mix and are thus important determinants of population structure. Detailed information on fish migration and movements is becoming more accessible through advances in telemet...
With the accelerating pace of global change, it is imperative that we obtain rapid inventories of the status and distribution of wildlife for ecological inferences and conservation planning. To address this challenge, we launched the SNAPSHOT USA project, a collaborative survey of terrestrial wildlife populations using camera traps across the United States. For our first annual survey, we compiled data across all 50 states dur...
Many demersal marine fish species depend on a dispersive larval stage that connects geographically discrete sub‐populations. Understanding connectivity between these sub‐populations is necessary to determine stock structure, which identifies the appropriate spatial scale for fishery management. Such connectivity is poorly understood for King George whiting ( Sillaginodes punctatus ; Perciformes) in South Australia's gulf syste...
Age validation, growth and population characteristics of greenback flounder ( Rhombosolea tapirina ) in a large temperate estuaryNARA Subscribed
The greenback flounder ( Rhombosolea tapirina ) is an important fishery species in southern Australia and New Zealand, whose demographic processes are poorly understood. This study developed an ageing protocol based on otolith interpretation and provided estimates of age‐based data for an exploited population in the estuary of Australia's largest river system. The otoliths fulfilled three criteria that established their useful...
The spawning dynamics of snapper ( Chrysophrys auratus ) in northern Spencer Gulf, South AustraliaNARA Subscribed
This study investigated the inter‐ and intra‐annual variation in the spawning dynamics of snapper ( Chrysophrys auratus ). Reproductive samples from northern Spencer Gulf, South Australia were collected over three seasons (2005/06, 2006/07 and 2007/08) and were analysed macro and microscopically. Spawning activity was determined by calculating estimates of spawning fraction and batch fecundities. The onset of spawning occurred...
