Sep 2, 2020 · Here we show that by using a single phage reference genome to recruit metagenomic reads from distant cryoconite holes and backfilling the gaps in silico, we can infer the variable genes present...

Cryoconite holes may therefore be considered as small, naturally occurring microcosm-like ecosystems. In this study, we took advantage of their unique and consistent nature to recruit metagenomic...

Sep 2, 2020 · Here, we show that phages with near-identical core genomes in distant, discrete aquatic ecosystems maintain diversity by possession of numerous flexible gene modules, where homologous genes present in the pan-genome interchange to create new phage variants.

Jul 1, 2016 · On Snowball Earth, cryoconite pans provided stable interconnected habitats for eukaryotes tolerant of fresh to brackish cold water on an ablation surface 60 million km (2) in area. Flushing and...

Oct 18, 2023 · These findings enhance our understanding of glacier cryoconite microbiome variation on a hemispheric scale and indicate the response mechanisms to radiation stress, which will support forecasts of the ecological consequences of future climate change.

On Snowball Earth, cryoconite pans provided stable interconnected habitats for eukaryotes tolerant of fresh to brackish cold water on an ablation surface 60 million km 2 in area. Flushing and burial of organic matter was a potential source of atmospheric oxygen.

Dec 12, 2024 · Analyses of samples of cryoconite, a sediment that accumulates on glaciers, reveal not only differences in concentrations between the hemispheres but also indicate unprecedented isotope anomalies that may be related to …

Here we show that by using a single phage reference genome to recruit metagenomic reads from distant cryoconite holes and backfilling the gaps in silico, we can infer the variable genes present in a population of phages (the pan-genome) and determine the underlying mechanisms generating diversity.

Dec 12, 2023 · This study is the first to describe the distribution of microbial pigments in cryoconite from Tibetan glaciers, providing additional support on the influence of algal pigment on glacier retreat.

Dec 12, 2024 · At its bottom, there is a dark sediment called cryoconite. It contains organic material and contaminants, i.e. radionuclides, heavy metals, pesticides, microplastics, or antibiotics. This...
