Stomach contents and stable isotope analysis reveal Antarctic prey in short-tailed shearwaters sampled at sea
Short-tailed shearwaters Ardenna tenuirostris are seasonally abundant consumers in the Southern Ocean, but their diet in this region is debated....

Antarctic marine sediment as a source of filamentous fungi-derived antimicrobial and antitumor compounds of pharmaceutical interest
Antarctica harbors a microbial diversity still poorly explored and of inestimable biotechnological value. Cold-adapted microorganisms can produce a...

Communities of culturable freshwater fungi present in Antarctic lakes and detection of their low-temperature-active enzymes
We evaluated the diversity and enzymatic activities of culturable fungi recovered from cotton baits submerged for 2 years in Hennequin Lake, King...

Summer activity patterns for a moss and lichen in the maritime Antarctic with respect to altitude
There is considerable scientific interest as to how terrestrial biodiversity in Antarctica might respond, or be expected to respond, to climate...

Distribution patterns of selenium and its fractions in penguin and seal colony soil profiles in response to their population dynamics in maritime Antarctica
Currently, most studies focus on the spatial distribution patterns of selenium (Se) and its fractions in the horizontal surface soils with much less...

Sub-Antarctic High Andean “Gardeners”: Cultivating Caring Relationships
This chapter presents a case study of the Field Environmental Philosophy four-step cycle methodology in the sub-Antarctic high Andean zone. First,...

Dispersal potential does not predict recent range expansions of sub-Antarctic plant species
Dispersal influences many key aspects of plant ecology at both fine- and broad scales. However, dispersal events are challenging to quantify as they...

Rapid growth rate responses of terrestrial bacteria to field warming on the Antarctic Peninsula
Ice-free terrestrial environments of the western Antarctic Peninsula are expanding and subject to colonization by new microorganisms and plants,...

Gentoo Penguins (Pygoscelis papua) started using mosses as nesting material in the southernmost colony on the Antarctic Peninsula (Cape Tuxen, Graham Land)
The population of Gentoo Penguins ( Pygoscelis papua ) in the maritime Antarctic is rapidly increasing. Due to regional climate changes, they colonise...

Thermal responses of the embryos and early instar larvae of the Antarctic midge Belgica antarctica (Insecta: Diptera)
The Antarctic midge, Belgica antarctica , is the only insect that is endemic to the Antarctic Peninsula and its offshore islands. The final (fourth)...

Drone-based monitoring and geomorphology of southern giant petrel nests near Palmer Station, western Antarctic Peninsula
Human activities and climate change threaten seabirds globally, and many species are declining from already small breeding populations. Monitoring of...

Rethinking the sub-Antarctic terrestrial N-cycle: evidence for organic N acquisition by Marion Island grasses
Organic N (oN, e.g., amino acids) is an important N-resource for plants in soils replete with oN but not inorganic N (iN; i.e., NH 4 + and NO 3 − ), such...

Highly specialized bacterial communities within three distinct rhizocompartments of Antarctic hairgrass (Deschampsia antarctica Desv.)
Antarctic hairgrass, Deschampsia antarctica Desv. ( Poaceae ), is one of the two flowering plants that have an established presence in Maritime...

Volume backscattering spectra measurements of Antarctic krill using a broadband echosounder
For the acoustic inference of lengths and orientation angles of Antarctic krill (krill), reliable theoretical acoustic scattering models and...

Insights into abundance, adaptation and activity of prokaryotes in arctic and Antarctic environments
Microorganisms perform many important functions in Arctic and Antarctic environments, but their activity and occurrence can be difficult to detect....
-
Diversity of pollen grains transported from South America to the Antarctic Peninsula through atmospheric dispersal
The geographical isolation of Antarctica and the low temperatures resulting from the Antarctic albedo and the Circumpolar Current are key factors...

Cannibalism in southern giant petrels (Macronectes giganteus) at Nelson Island, Maritime Antarctic Peninsula
Southern giant petrels ( Macronectes giganteus ) are a scavenger and predatory species with highly opportunistic feeding habits. Although cannibalism...

Diversity and functionality of soil prokaryotic communities in antarctic volcanic soils: insights from penguin-influenced environments
In the nutrient-limited Antarctic terrestrial habitat, penguins transfer a significant amount of nutrients from the marine to the terrestrial...

Giant kelp (Macrocystis pyrifera) morphological and reproductive strategies in two contrasting sub-Antarctic forests
Sub-Antarctic giant kelp ( Macrocystis pyrifera ) forests have remained relatively wild and far from anthropogenic pressures. However, they are...

Metabolic fingerprinting of the Antarctic cyanolichen Leptogium puberulum–associated bacterial community (Western Shore of Admiralty Bay, King George Island, Maritime Antarctica)
Lichens are presently regarded as stable biotopes, small ecosystems providing a safe haven for the development of a diverse and numerous microbiome....
