Variability in Host Specificity and Functional Potential of Antarctic Sponge-Associated Bacterial Communities

open access: yesFrontiers in Microbiology, 2022
Sponge-associated microorganisms are essential for sponge survival. They play an important role in recycling nutrients and, therefore, in the maintenance of the ecosystem.

Effects of Climate Change Stressors on the Prokaryotic Communities of the Antarctic Sponge Isodictya kerguelenensis

open access: yesFrontiers in Ecology and Evolution, 2020
Microbial symbionts of marine sponges play important roles for the hosts and also for their ecosystems. The unique tolerance of marine sponges to a wide diversity of microbial symbionts allows them to acquire a wide variety of “evolutionary solutions” to

Parasitic diatoms inside antarctic sponges

open access: yesThe Biological Bulletin, 2000
Antarctic sponges may host large populations of planktonic and benthic diatoms. After settling on the sponge, these diatoms enter its body through pinacocytes (1) and form, there, large mono- or pauci-specific assemblages. Yet the total amount of carbohydrates in the invaded sponge tissue is inversely correlated with that of chlorophyll-a.

Phylogenetic Reassessment of Antarctic Tetillidae (Demospongiae, Tetractinellida) Reveals New Genera and Genetic Similarity among Morphologically Distinct Species. [PDF]

open access: yesPLoS ONE, 2016
Species of Tetillidae are distributed worldwide. However, some genera are unresolved and only a few genera and species of this family have been described from the Antarctic.

Global diversity of sponges (Porifera). [PDF]

open access: yes, 2012
With the completion of a single unified classification, the Systema Porifera (SP) and subsequent development of an online species database, the World Porifera Database (WPD), we are now equipped to provide a first comprehensive picture of the global ...

Cytotoxic activity of marine sponge extracts from the sub-Antarctic Islands and the Southern Ocean

open access: yesSouth African Journal of Science, 2016
Over the past 50 years, marine invertebrates, especially sponges, have proven to be a valuable source of new and/or bioactive natural products that have the potential to be further developed as lead compounds for pharmaceutical applications.

How does heat stress affect sponge microbiomes? Structure and resilience of microbial communities of marine sponges from different habitats

open access: yesFrontiers in Marine Science, 2023
IntroductionSponges are key components of marine benthic communities, providing many ecosystem functions and establishing close relationships with microorganisms, conforming the holobiont.

Biological characterisation of Haliclona (?gellius) sp.: sponge and associated microorganisms. [PDF]

open access: yes, 2009
We have characterised the northern Pacific undescribed sponge Haliclona (?gellius) sp. based on rDNA of the sponge and its associated microorganisms.

High similarity in the microbiota of cold-water sponges of the Genus Mycale from two different geographical areas [PDF]

open access: yesPeerJ, 2018
Sponges belonging to genus Mycale are common and widely distributed across the oceans and represent a significant component of benthic communities in term of their biomass, which in many species is largely composed by bacteria.

Sponge richness on algae-dominated rocky reefs in the western Antarctic Peninsula and the Magellan Strait

open access: yesPolar Research, 2016
Sponges are important components of high-latitude benthic communities, but their diversity and abundance in algal-dominated rocky reefs has been underestimated because of the difficulty of in situ identification.
