The 100 Diatom Genomes Project

Thomas Möck, Gust Bilcke, Eliott Flaum, Shunan Fu et autres

One hundred diatom species have been selected for genome and transcriptome sequencing. The 100 Diatom Genomes Project aims to provide a scalable framework for understanding diatom biodiversity, ecology and evolution, and for investigating their use in biotechnology.

Distinct benthic and planktonic microbial communities within the stratified water column of the perennially ice-covered Lake Joyce, Antarctica

C Greco, I Hawes, D Y Sumner, T Mackey et autres

Perennially ice-covered lakes are hotspots of biodiversity and biomass accumulation in polar deserts. Many Antarctic perennially ice-covered lakes are density stratified, within which an oxygenated upper layer overlies deeper, darker anoxic waters. We carried out the first 16S and 18S rRNA gene …

Seasonal thawing of high Arctic soils triggers selective microbial growth and predation

Margaret A. Cramm, Ömer K. Coskun, Francesco Montemagno, Matteo Selci et autres

ABSTRACT Climate warming threatens Arctic permafrost with seasonal cycles of freezing and thawing. Arctic soil microorganisms regulate carbon stocks and greenhouse gas exchanges with the atmosphere, yet their precise seasonal growth and dormancy dynamics, and their responses to permafrost thaw, are not …

Population and herbarium genomics provide a comprehensive framework for a revision of Microcoleus (Cyanobacteria)

Svatopluk Skoupý, Aleksandar Stanojković, Jeffrey R. Johansen, Dale A. Casamatta et autres

Microcoleus is a cosmopolitan, filamentous cyanobacterium and a key component of biological soil crusts-complex microbial communities essential for primary production in diverse terrestrial environments. Here, we performed a taxonomic revision of several species of Microcoleus based on a large population genomic dataset. …

Freshwater biodiversity in a rapidly changing Arctic: An expert horizon scan of key research questions

Joseph M. Culp, Michael Power, Kirsten S. Christoffersen, Willem Goedkoop et autres

Arctic freshwater biodiversity is rapidly changing due to climate warming, resource extraction, infrastructure development, and landscape transformation. To improve understanding, predict future responses, and inform policy formulation, research needs must be clearly identified. Using a horizon scan survey, Arctic freshwater experts from …

Environmental filtering drives cryptic diversity and shifting interaction networks across lake, ephemeral pond, and desiccated microbial mat communities in the Untersee Oasis, East Antarctica

Lara Vimercati, Imogen Chakrabarti, Annabel Lindley, Carla Greco et autres

Abstract Antarctic lakes and surrounding habitats are natural laboratories for studying microbial ecology in extreme environments, yet assembly and dispersal across these systems remain poorly understood. We analyzed bacterial (16S rRNA) and eukaryotic (18S rRNA) communities across benthic lake mats, pond mats, …

Mixture Density Networks Improve Inter-Sensor Consistency of Optical Water Type Classification

Davide Lomeo, Stefan G. H. Simis, Mel Warren, David Moffat et autres

In aquatic remote sensing, optical water type (OWT) preclassification has been used to map suitable algorithms to optically diverse targets and over optical gradients. However, current methods can yield inconsistent-type assignments across sensors with different spectral capabilities. Probabilistic neural networks (NNs) are …

Limestone-Based Hybrid Passive Treatment for Copper-Rich Acid Mine Drainage: From Laboratory to Field

Joshua Pocaan, Jaica Mae Pagaduan, Johara Capingian, Michelle Airah N. Pablo et autres

Acid mine drainage (AMD) is an environmental concern that needs to be addressed by some mining industries because of its high concentrations of metals and acidity that destroy affected ecosystems. Its formation typically persists beyond the operating life of a mine site. …

Colour-informed ecoregion analysis highlights a satellite capability gap for spatially and temporally consistent freshwater cyanobacteria monitoring

Davide Lomeo, Stefan Simis, Nick Selmes, Anne D. Jungblut et autres

Cyanobacteria blooms pose significant risks to water quality in freshwater ecosystems worldwide, with implications for human and animal health. Constructing consistent records of cyanobacteria dynamics in complex inland waters from satellite imagery remains challenged by discontinuous sensor capabilities, particularly with regard to …
