Stratified lakes and ponds featuring steep oxygen gradients are significant net sources of greenhouse gases and hotspots in the carbon cycle. Despite their significant biogeochemical roles, the microbial communities, especially in the oxygen depleted compartments, are poorly known. Here, we present a comprehensive dataset including 267 shotgun metagenomes from 41 stratified lakes and ponds mainly located in the boreal and subarctic regions, but also including one tropical reservoir and one temperate lake. For most lakes and ponds, the data includes a vertical sample set spanning from the oxic surface to the anoxic bottom layer. The majority of the samples were collected during the open water period, but also a total of 29 samples were collected from under the ice. In addition to the metagenomic sequences, the dataset includes environmental variables for the samples, such as oxygen, nutrient and organic carbon concentrations. The dataset is ideal for further exploring the microbial taxonomic and functional diversity in freshwater environments and potential climate change impacts on the functioning of these ecosystems. ...

Additional information about fundingThe sequencing was funded by a grant from the Science for Life Laboratory biodiversity program and SciLifeLab fellows program. Sequencing was performed by the SNP&SEQ Technology Platform in Uppsala. The facility is part of the National Genomics Infrastructure (NGI) Sweden and Science for Life Laboratory. The SNP&SEQ Platform is also supported by the Swedish Research Council and the Knut and Alice Wallenberg Foundation. The computations were performed on resources provided by SNIC through Uppsala Multidisciplinary Center for Advanced Computational Science (UPPMAX) under Project SNIC snic2020-5-19. We also want to thank the SciLifeLab Data Center for helping us to make the data available more freely. Samplings were funded by miscellaneous grants from the Academy of Finland, INTERACT, K&A Wallenberg Foundation, Olsson-Borgh Foundation, Swedish Research Council, and Swedish Research Council Formas.

Vertical stratification patterns of methanotrophs and their genetic controllers in water columns of oxygen-stratified boreal lakes Rissanen, Antti J.; Saarela, Taija; Jäntti, Helena; Buck, Moritz; Peura, Sari; Aalto, Sanni L.; Ojala, Anne; Pumpanen, Jukka; Tiirola, Marja; Elvert, Marcus; Nykänen, Hannu (Oxford University Press, 2021)The vertical structuring of methanotrophic communities and its genetic controllers remain understudied in the water columns of oxygen-stratified lakes. Therefore, we used 16S rRNA gene sequencing to study the vertical ...
Allochthonous carbon is a major regulator to bacterial growth and community composition in subarctic freshwaters Roiha, Toni; Peura, Sari; Cusson, Mathieu; Rautio, Milla (Nature Publishing Group, 2016)In the subarctic region, climate warming and permafrost thaw are leading to emergence of ponds and to an increase in mobility of catchment carbon. As carbon of terrestrial origin is increasing in subarctic freshwaters ...
Metagenomic insights into strategies of aerobic and anaerobic carbon and nitrogen transformation in boreal lakes Peura, Sari; Sinclair, Lucas; Bertilsson, Stefan; Eiler, Alexander (Nature Publishing Group, 2015)Thousands of net-heterotrophic and strongly stratifying lakes dominate the boreal landscape. Besides their central role as emitters of greenhouse gases, we have only recently begun to understand the microbial systems ...

Novel Autotrophic Organisms Contribute Significantly to the Internal Carbon Cycling Potential of a Boreal Lake Peura, Sari; Buck, Moritz; Aalto, Sanni L.; Morales, Sergio E.; Nykänen, Hannu; Eiler, Alexander (American Society for Microbiology, 2018)Oxygen-stratified lakes are typical for the boreal zone and also a major source of greenhouse gas emissions in the region. Due to shallow light penetration, restricting the growth of phototrophic organisms, and large ...
