Glacial melting: an overlooked threat to Antarctic krill
TLDR
The experimental results showed that large quantities of lithogenic particles affected krill feeding, absorption capacity and performance after only 24 h of exposure, and negative effects were related to both the threshold concentrations and the size of the suspended particles. Expand
Seasonal trophic ecology of the dominant Antarctic coral Malacobelemnon daytoni (Octocorallia, Pennatulacea, Kophobelemnidae).
TLDR
Results support the hypothesis that resuspension events may be an important source of energy, reducing the seasonality of food depletion periods in winter, and suggest an omnivorous diet and opportunistic feeding strategy for Malacobelemnon daytoni. Expand
Suspension feeders as natural sentinels of the spatial variability in food sources in an Antarctic fjord: A stable isotope approach
Abstract We examined the effect of glacial melt-related retreat environmental conditions on the spatial heterogeneity of food sources for Antarctic nearshore marine benthic communities of PotterExpand
A re-evaluation of morphological characters of the invasive ascidian Corella eumyota reveals two different species at the tip of South America and in the South Shetland Islands, Antarctica
TLDR
This work strongly indicates that there are two different species of solitary ascidian Corella eumyota from South America and Corella antarctica Sluiter, 1905) from Antarctica, which has been till now considered a junior synonym of the former. Expand
Role of suspension feeders in antarctic pelagic-benthic coupling: Trophic ecology and potential carbon sinks under climate change.
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 negativeExpand
Not as clear as expected: what genetic data tell about Southern Hemisphere corellids (Ascidiacea: Phlebobranchia)
ABSTRACT The morphology of corellids (Ascidiacea) has led to numerous misidentifications and wrong taxonomic decisions over the last century. Paradoxically, the morphology has also enabled newExpand
GENOMIC AND TRANSCRIPTOMIC DIVERSITY OF ANTARCTIC ORGANISM
S SUBMITTED TO THE (CANCELLED) SCAR 2020 OSC IN HOBART SESSION 19 SCAR OPEN SCIENCE CONFERENCE 2020
Deep-sea ascidians (Chordata, Tunicata) from the SW Atlantic: species richness with descriptions of two new species.
The understudied deep-sea benthic communities from the Southwestern Atlantic continental slope (200 m-3000 m depth) were sampled on August 2012 in an area located around 38°S that included the MarExpand
Early developmental stages of native populations of Ciona intestinalis under increased temperature are affected by local habitat history
TLDR
Anthropogenic stressors can shape early developmental stages of Ciona intestinalis, increasing their resilience to predicted future heatwave scenarios when compared with control populations from undisturbed locations. Expand
New insights into the autecology of the two sympatric fish species Notothenia coriiceps and N. rossii from western Antarctic Peninsula: A trophic biomarkers approach
TLDR
FA profiles and SI composition of muscle tissue from two sympatric Antarctic fish species—Notothenia rossii and N. coriiceps—that are key components in the inshore ecosystem of the South Shetland Islands are compared to indicate whether both nototheniids are feeding mainly on another food source or that FA bioconversion takes place.
