Effects of hydrocarbon spills on the temperature and moisture regimes of Cryosols in the Ross Sea region [PDF]

, 2002
Hydrocarbon spills have occurred on Antarctic soils where fuel oils are utilized, moved or stored. We investigated the effects of hydrocarbon spills on soil temperature and moisture regimes by comparing the properties of existing oil contaminated sites ...

Biogeographic survey of soil bacterial communities across Antarctica

Microbiome
Background Antarctica and its unique biodiversity are increasingly at risk from the effects of global climate change and other human influences. A significant recent element underpinning strategies for Antarctic conservation has been the development of a

Advances in organic UV filters for sunscreens over the past decade

Photochemistry and Photobiology, EarlyView.
Highlighted organic UV filter frameworks that have been described for sunscreens over the past decade divided into three groups: derivatives of or inspired by approved organic UV filters, natural product‐based compounds, and miscellaneous. Abstract Ultraviolet (UV) radiation is a major environmental factor in photoaging, erythema, and skin cancer ...

Preliminary analysis of life within a former subglacial lake sediment in Antarctica [PDF]

, 2013
Since the first descriptions of Antarctic subglacial lakes, there has been a growing interest and awareness of the possibility that life will exist and potentially thrive in these unique and little known environments. The unusual combination of selection

Musculoskeletal (Mal)adaptations in Response to a > 30 000‐km Running Challenge

Journal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 5, October 2026.
ABSTRACT Background Ultra‐endurance sports are increasingly popular, yet the long‐term physiological consequences of sustained extreme training loads remain poorly understood. In particular, the effects of prolonged ultra‐endurance exercise on skeletal muscle structure, function and molecular remodelling are largely unknown.

Culturable bacteria associated with Antarctic lichens: affiliation and psychrotolerance [PDF]

Polar Biology, 2009
Antarctic habitats harbour yet unexplored niches for microbial communities. Among these, lichen symbioses are very long-living and stable microenvironments for bacterial colonization. In this work, we present a first assessment of the culturable fraction of bacteria associated with Antarctic lichens.

Aerobiology over Antarctica – A new Initiative for Atmospheric Ecology [PDF]

, 2016
The role of Aerial dispersal in shaping patterns of biodiversity remains poorly understood, mainly due to a lack of coordinated efforts in gathering data at appropriate temporal and spatial scales.
