Diverse hypolithic refuge communities in the McMurdo Dry Valleys [PDF]

open access: yes, 2010
Hyper-arid deserts present extreme challenges to life. The environmental buffering provided by quartz and other translucent rocks allows hypolithic microbial communities to develop on sub-soil surfaces of such rocks.

Collection of Environmental Variables and Bacterial Community Compositions in Marian Cove, Antarctica, during Summer 2018

open access: yesData, 2021
Marine bacteria, which are known as key drivers for marine biogeochemical cycles and Earth’s climate system, are mainly responsible for the decomposition of organic matter and production of climate-relevant gases (i.e., CO₂, N₂O, and CH₄).

Reproductive endosymbiotic bacteria of Antarctic springtails: on the verge of new discoveries?

open access: yesУкраїнський антарктичний журнал
Endosymbiotic bacteria infect a vast number of invertebrate representatives from diverse taxa. This study reviews the results of identifying endosymbiotic bacteria (specifically the genera Wolbachia, Cardinium, Rickettsia, Arsenophonus and Spiroplasma ...

Plant growth promoting properties of an antarctic strain Amycolatopsis sp. Cq 72-27

open access: yesУкраїнський антарктичний журнал, 2023
Unique biotopes can be a source of new plant growth promotion (PGP) bacteria with rare properties. The Antarctic habitat is an attractive location for research, as it is characterized by many stress factors, and the local microbiota is under permanent ...

First record of the endophytic bacteria of Deschampsia antarctica Ė. Desv. from two distant localities of the maritime Antarctic [PDF]

open access: yes, 2021
Endophytic bacteria, recognized for their beneficial effects on plant development and adaptation, can facilitate the survival of Antarctic plants in severe environments. Here we studied endophytes of the vascular plant Deschampsia antarctica Ė.

Trematocine, a Novel Antimicrobial Peptide from the Antarctic Fish Trematomus bernacchii: Identification and Biological Activity

open access: yesAntibiotics, 2020
Antimicrobial peptides (AMPs) are short peptides active against a wide range of pathogens and, therefore, they are considered a useful alternative to conventional antibiotics.

Airborne bacterial populations above desert soils of the McMurdo Dry Valleys, Antarctica [PDF]

open access: yes, 2013
Bacteria are assumed to disperse widely via aerosolized transport due to their small size and resilience. The question of microbial endemicity in isolated populations is directly related to the level of airborne exogenous inputs, yet this has proven hard

Antarctic marine biodiversity and deep-sea hydrothermal vents.

open access: yesPLoS Biology, 2012
The diversity of many marine benthic groups is unlike that of most other taxa. Rather than declining from the tropics to the poles, much of the benthos shows high diversity in the Southern Ocean. Moreover, many species are unique to the Antarctic region.

Interplanetary frontiers: terraforming from an invasion science perspective

open access: yesOikos, EarlyView.
The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...

Estimating the distribution of demand for Antarctic krill (Euphauisa superba) from land-based predators at South Georgia [PDF]

open access: yes, 2007
South Georgia is renowned for the abundance of Antarctic krill (Euphausia superba) and a range of krill predators. Variability in krill availability at a range of scales, and the consequences of this for predator-prey interactions, mean that quantifying ...
