Summary: A novel aerobic, Gram-staining-negative, non-motile, short-rod-shaped strain, named Orrella daihaiensis sp. nov., was isolated from Daihai Lake in Inner Mongolia, China. The strain showed high similarity to Orrella marina based on 16S rRNA gene sequences analysis. It exhibited specific growth characteristics and cellular structures under certain conditions of light, temperature, and salinity. The polyphasic analysis confirmed that the strain represents a new species within the genus Orrella.

Summary: This study investigated the phylogenetic diversity of prokaryotes in hypolithic communities in the Taylor Valley, McMurdo Dry Valleys, Antarctica. Results showed that the communities are heterogeneous at very small spatial scales, likely due to stochastic effects such as dispersal limitations. This heterogeneity is consistent with the physically isolated nature of hypolithic communities and the absence of a liquid continuum for microbial transport between communities.

Summary: Bacterial diversity and soil physicochemistry varied across intact and degraded zones in the Portulacaria afra-dominated succulent thicket vegetation. The restored zone showed intermediate characteristics between intact and degraded zones, with plant presence being a key driver of microbial community differences. The study provides baseline information for further research on the restoration of degraded succulent thicket ecosystems.

Summary: Arid ecosystems cover a significant portion of the Earth's terrestrial surface and contribute to the global nitrogen pool. These ecosystems are characterized by extreme conditions that limit the presence of macrofauna and flora and hinder plant growth and productivity. Microbes play a crucial role in the nitrogen cycling processes that drive primary production and nutrient biogeochemical cycling in these ecosystems. This survey provides insights into the current understanding of microbial-mediated nitrogen processes in different edaphic and refuge niches in arid environments.

Summary: Antarctic terrestrial biodiversity is under multiple threats, and current conservation efforts are deemed insufficient. A participatory study estimates that up to 65% of native terrestrial taxa and land-associated seabirds may decline by 2100. Implementing 10 key threat management strategies could benefit up to 84% of Antarctic taxa.

Summary: The Namib Desert in south-western Africa is one of the oldest deserts in the world and has unique geographical, biological, and climatic features. This study investigated the diversity and function of fungal communities in Namib Desert soils across different regions and found that certain fungal taxa consistently dominated the communities. The study also revealed that the assembly of fungal communities in the desert was influenced by both deterministic and stochastic processes, with limitations to fungal dispersal caused by the inland limit of fog penetration.

Summary: Microbial communities and nutrient dynamics in glaciers and ice sheets are constantly changing due to hydrological conditions. Glaciers and ice sheets act as bioreactors, as microbiomes transform nutrients and impact meltwater chemistry. Global warming affects nutrient and cell export, altering proglacial systems. This review integrates current understanding of glacial hydrology, microbial activity, and nutrient and carbon dynamics, highlighting their interdependence, variability, and impact on proglacial environments.

Summary: By analyzing metagenome libraries derived from the sequencing of a Later Stone Age hunter-gatherer child who lived near Ballito Bay, South Africa, about 2000 years ago, ancient DNA sequences homologous to the flea-borne typhus-like pathogen Rickettsia felis were identified, and an ancient R. felis genome was reconstructed. This provides ancient genomic evidence for the presence of Rickettsia felis in human remains from 2000 years ago, reframing previous hypotheses of R. felis as a novel or emergent pathogen in modern humans.
