Geology defines microbiome structure and composition in nunataks and valleys of the Sør Rondane Mountains, East Antarctica

Frontiers in Microbiology
Understanding the relation between terrestrial microorganisms and edaphic factors in the Antarctic can provide insights into their potential response to environmental changes. Here we examined the composition of bacterial and micro-eukaryotic communities

Sun exposure drives Antarctic cryptoendolithic community structure and composition [PDF]

, 2019
The harsh environmental conditions of the ice-free regions of Continental Antarctica are considered one of the closest Martian analogues on Earth. There, rocks play a pivotal role as substratum for life and endolithism represents a primary habitat for ...

Bridging maternal effects and epitranscriptomics: A novel perspective in developmental biology

Developmental Dynamics, EarlyView.
Abstract Maternal effects, encompassing both genetic (maternally expressed gene products) and non‐genetic (maternal state) influences, are powerful determinants of offspring phenotype, yet their RNA‐level mechanisms remain incompletely resolved. In parallel, epitranscriptomics, an emerging field centered on chemical modifications to RNA, has revealed ...

Projected Warming of the Southern Ocean Disrupts Embryonic Development and Hatch Timing in Antarctic Fish

Global Change Biology Communications, EarlyView.
Embryos are particularly sensitive to thermal challenge. Antarctic fish embryos raised at projected Southern Ocean temperatures hatch during the winter, have a high incidence of morphological abnormalities, have shorter body lengths, and express genes indicative of cellular stress.

Convergent evolution of metabolic functions: Evidence from the gut microbiomes of humans and dogs

iMetaOmics, EarlyView.
Dogs have undergone convergent evolution in their genome with humans in long‐term co‐living. Studies have shown that the gut microbiomes of dogs exhibit greater similarity to those of humans compared to mice and pigs. In our study, we first compared the gut microbiomes of macaques, three dog groups, and two wolf groups to those in humans.

Biosynthesis gene cluster‐containing species drive microbial community stability under thermal stress through enhanced ecological cohesion

iMetaOmics, EarlyView.
The study framework for exploring microbial community assembly and community stability of biosynthesis gene cluster (BGC)‐containing species under thermal stress (20°C–65°C) during 39 days of spontaneous fermentation. Temperature gradients during spontaneous fermentation reshape microbial community assembly, driving pronounced succession in both ...
