Hidden diversity in Antarctica: Molecular and morphological evidence of two different species within one of the most conspicuous ascidian species
(John Wiley & Sons Ltd, 2020-08-15)
The Southern Ocean is one of the most isolated marine ecosystems, characterized by high levels of endemism, diversity, and biomass. Ascidians are among the dominant groups in Antarctic benthic assemblages; thus, recording ...
When shape matters: Strategies of different Antarctic ascidians morphotypes to deal with sedimentation
(Elsevier, 2014-05)
Climate change leads to increased melting of tidewater glaciers in the Western Antarctic Peninsula region and sediment bearing glacial melt waters negatively affects filter feeding species as solitary ascidians. In previous ...
Role of suspension feeders in antarctic pelagic-benthic coupling: Trophic ecology and potential carbon sinks under climate change
(Elsevier, 2019-12)
Sea-ice and coastal glacier loss in the Western Antarctic Peninsula open new ice-free areas. They allowing primary production and providing new seabed for colonisation, both acting as a negative feedback of climate change. ...
Feeding ecology of benthic filter-feeders at Potter Cove, an Antarctic coastal ecosystem
(Springer, 2008-03)
A rich benthic filter-feeding community is present at Potter Cove, South Shetland, in spite of some usually unfavorable conditions affecting their feeding ecology, such as low phytoplankton production in summer and high ...
Bulk gut content and mantle glycogen content of antarctic ascidians from different stations inside Potter Cove
The gut content (dry mass and organic matter fraction) of three antarctic ascidians (Corella antarctica, Cnemidocarpa verrucosa, and Molgula pedunculata) under different sedimentation regimes were estimated together with ...
Sessile macro-epibiotic community of solitary ascidians, ecosystem engineers in soft substrates of Potter Cove, Antarctica
(Co-action Publishing, 2015-01)
The muddy bottoms of inner Potter Cove, King George Island (Isla 25 de Mayo), South Shetlands, Antarctica, show a high density and richness of macrobenthic species, particularly ascidians. In other areas, ascidians have ...
Enlace bento-pelágico en un ecosistema costero antártico afectado por el deshielo: Una aproximación ecológica
(2018-03-20)
Las conexiones estructurales y funcionales entre los procesos físicos, químicos, biológicos y geológicos que ocurren entre la columna de agua y el fondo marino, se conocen generalmente con el nombre de acoplamiento o enlace ...
