Phytoplankton blooms structure primary production and food‐web dynamics in the Gulf of Alaska, yet their response to recent warming and marine heatwaves (MHWs) remains poorly described. Using a parametric Gaussian framework applied to 21 years of satellite chlorophyll a (Chl a ), this study classified daily Chl a timeseries into double‐bloom, single spring‐bloom, single fall‐bloom, and no‐bloom regimes and related these to lar...
Since their discovery, the question of the phylogenetic position of Microcerberidae within Isopoda has been widely debated. Initially perceived as close relatives of the Anthuridae, the debate has shifted towards considering them either as a sister group of Asellota or positioned within the Asellota in their own right. In this study, we used sequence data for eight slow‐evolving nuclear genes in 37 isopod taxa to test for the...
Environmental filtering shapes biosynthetic potential and resistome of antarctic microbiomesNARA Subscribed
Environmental filtering is a major driver of microbial community assembly in Antarctic ecosystems, yet its influence on biosynthetic potential and antimicrobial resistance remains poorly understood. Here, we analyzed 319 medium- to high-quality metagenome-assembled genomes (MAGs) recovered from four Antarctic sites (Whalers Bay, Crater Lake, Fumarole Bay, and Hannah Point) to investigate the relationship between geochemical gr...

The high-value tropical sea cucumber Holothuria ( Metriatyla ) scabra or sandfish is central to the ‘400+ year old global’, bêche-de-mer trade. Consequently, it has faced heavy exploitation and has become extirpated in some regions within its broader Indo-Pacific natural distribution. Recent molecular evidence has provided clarity on its taxonomic identity, indicating it comprises a species complex, with four broad lineages de...
World Health Organization (WHO) guidance on the management of cyanobacteria in recreational waters provides a comprehensive framework for reducing human health risks. To provide a global overview of how cyanobacterial risks in recreational waters are managed and to better understand capacity gaps and best practice, we surveyed expert opinion across the world. A total of 161 survey responses were collected from 49 countries. Re...
Mercury (Hg), and specifically methylmercury (MeHg), is a contaminant of global concern to humans and wildlife, but there is still limited understanding of its effects on many taxa. Amphibians are closely associated with water, where Hg is converted to MeHg, and high concentrations of MeHg can reduce survival of amphibians in the wild. However, limited non-lethal proxies exist for estimating MeHg bioaccumulation in amphibian l...
Conservation translocations require careful assessment of dietary resources to ensure population viability. Here, we used environmental DNA metabarcoding to characterise fungal assemblages across three major habitat types on Dirk Hartog Island, Western Australia, prior to the planned reintroduction of two threatened mycophagous species: the boodie ( Bettongia lesueur ) and woylie ( Bettongia ogilbyi ). We detected 243 fungal A...
The impact of perceived human and computer interaction on collaborative learning: insights from the Map TaskNARA Subscribed
Learning new skills and information becomes more challenging as people get older, but learning collaboratively can provide benefits to learning in older age. Prior work has predominantly focused on improved learning in terms of accuracy and efficiency when interacting with another human compared to learning alone, while the potential benefits of a human learning with a computer are understudied. It has been reported that older...
Long-term predictive modeling of stream condition suggests wide-spread changes within the Chesapeake Bay Watershed, USANARA Subscribed
Stream ecosystems worldwide face ongoing degradation, underscoring the urgent need for conservation and restoration. Regional analyses of stream condition have been limited by sparse spatial and temporal data, particularly at long time scales. To address this gap, we used observed data to predict annual biological condition for 360,893 small, nontidal stream reaches in the Chesapeake Bay watershed from 1985 to 2023 (39 years)....
Pacific white shrimp ( Litopenaeus vannamei ) are among the most important aquaculture species but are highly susceptible to Vibrio infections. Novel disease management strategies are necessary. Previous studies have reported that peracetic acid (PAA) is an effective disinfectant, but its application in shrimp aquaculture remains underexplored. This study aimed to determine the median lethal concentration (LC 50 ) of PAA at tw...
