Biological Activities of Ethanolic Extracts from Deep-Sea Antarctic Marine Sponges
Marine Drugs, 2013 We report on the screening of ethanolic extracts from 33 deep-sea Antarctic marine sponges for different biological activities. We monitored hemolysis, inhibition of acetylcholinesterase, cytotoxicity towards normal and transformed cells and growth ...

Prokaryotic Diversity and Community Patterns in Antarctic Continental Shelf Sponges [PDF]
Frontiers in Marine Science, 2019 Marine sponges (Phylum Porifera) are globally distributed within marine and freshwater ecosystems. In addition, sponges host dense and diverse prokaryotic communities, which are potential sources of novel bioactive metabolites and other complex compounds.

Unveiling microbial guilds and symbiotic relationships in Antarctic sponge microbiomes [PDF]
Scientific ReportsMarine sponges host diverse microbial communities. Although we know many of its ecological patterns, a deeper understanding of the polar sponge holobiont is still needed.

The Microbial Ecology of Antarctic Sponges [PDF]
Microbial EcologyAbstract Microbial communities in Antarctic marine sponges have distinct taxonomic and functional profiles due to low temperatures, seasonal days and nights, and geographic isolation. These sponge holobionts contribute to nutrient cycling, structural habitat formation, and benthic ecosystem resilience.

Diversity and distribution patterns in high southern latitude sponges. [PDF]
PLoS ONE, 2012 Sponges play a key role in Antarctic marine benthic community structure and dynamics and are often a dominant component of many Southern Ocean benthic communities.

Silicon isotopes in Antarctic sponges: an interlaboratory comparison [PDF]
Antarctic Science, 2010 Abstract Cycling of deepwater silicon (Si) within the Southern Ocean, and its transport into other ocean basins, may be an important player in the uptake of atmospheric carbon, and global climate. Recent work has shown that the Si isotope (denoted by δ 29 Si or δ

Evolution and ecology of antarctic sponges [PDF]
, 2012 Sponges are abundant and species-rich in Antarctic waters, and play important roles in the benthic ecosystems of the continent. The taxonomy of Antarctic sponges is, to some extent, well established, yet the phylogenetic relationships of this fauna remain unknown.

Towards Key Principles of Host-Associated Microbiome Assembly. [PDF]
Ecol LettSymbiotic relationships between microbes and hosts frequently involve the assembly of complex microbial communities (i.e., the microbiome). Microbiome composition and function influence host life‐history traits, ecological trajectories of partners, and are often critical for host health.

Warm temperatures, cool sponges: the effect of increased temperatures on the Antarctic sponge Isodictya sp. [PDF]
PeerJ, 2019 Although the cellular and molecular responses to exposure to relatively high temperatures (acute thermal stress or heat shock) have been studied previously, only sparse empirical evidence of how it affects cold-water species is available.
