Climatic change in the Antarctic Peninsula has driven profound shifts seabed.
The Antarctic Peninsula is among the places on Earth that registered major warming in last 60 yr. Massive ice losses, represented by glacier retreat, ice‐shelf collapses and sea‐ice reduction are main impacts of this regional warming. loss sea‐bed coverage, one hand has been affecting benthic assemblages, but other it opening up new areas for colonisation. Potter Cove (South Shetland Islands) offered opportunity assessing both processes. We recently reported a sudden shift assemblages...
Extended glacier retreat is among the main consequences of rapid warming West Antarctic Peninsula. Particularly, in inner part Potter Cove (South Shetland Islands, Antarctica) large areas are now exposed to open sea conditions owing Fourcade glacier. During 2010 austral summer, underwater photographic surveys were undertaken by SCUBA diving up 30 m these new ice-free 80 from front. Our aim was investigate colonization and early succession benthic assemblages on soft-bottom areas. Here, we...
Knowledge of continental shelf faunal biodiversity Antarctica is patchy and as such, the ecology this unique ecosystem not fully understood. To end, we deployed baited cameras at 20 locations along ~ 500 km Western Antarctic Peninsula (WAP) depths from 90 to 797 m. We identified 111 taxa, with mud bottom accounting for 90% dominant (≥ 50% cover) habitat sampled. Amphipoda comprised 41% total maximum number individuals per camera deployment (MaxN) occurred on 75% deployments. Excluding taxon,...
This work completes and updates the information about diversity distribution of benthic assemblages in an Antarctic fjord (South Bay, Peninsula) 40 years after first only community-level study was conducted there. To determine community changes, a photographic survey at four sites with different substrate inclinations along bathymetric gradient 5–20 m depth. In total, 160 photoquadrats were analyzed, resulting total area m2. Sixty taxa represented by 12 phyla identified, which eight...
Tatián, M., Lagger, C., Demarchi, M. & Mattoni, C. (2011). Molecular phylogeny endorses the relationship between carnivorous and filter‐feeding tunicates (Tunicata, Ascidiacea).— Zoologica Scripta, 40 , 603–612. The of (animals considered closest relatives to vertebrates) is not yet completely defined, especially evolutionary relationships within class. studies do include particular benthic deep‐sea species that show morphological changes in evolution from filter feeding into a...
Abstract Kelp forests are one of the earth’s most productive ecosystems and at greatest risk from climate change, yet little is known regarding their future threats current conservation status. By combining a global remote sensing dataset floating kelp with data projections, we find that exposure to projected marine heatwaves will increase ∼8 times compared contemporary (2001-2020) for intermediate scenarios. While intensify all forests, refugia emerge some southern hemisphere which have...
The diversity of ascidians from the Southwestern Atlantic between 30ºS and 40ºS (southern Brazil, Uruguay northern Argentina) remains as one poorest known West Atlantic. objective this work is to compile, analyze discuss all published records Uruguay. They show historical relevance studies performed by Herdman, Monniot F. C. on collected at deep-sea stations HMS Challenger RV Atlantis II in Argentine Basin. Total literature include 38 ascidian species which are enumerated here for first...
Deep-sea benthic communities from the Weddell Sea, Antarctica, were sampled in JanuaryApril 2005 an area located between 61S70S and 0W49W. We found a total of eight ascidian species that belong to five different families, which one corresponded new species. These were: Protoholozoa pedunculata Kott, 1969; Corynascidia suhmi Herdman, 1882; Styela andeepensis Maggioni Tatin sp. nov.; Culeolus Herman, 1881; anonymus Monniot F. C., 1976; likae Sanamyan K. N., 2002; Oligotrema lyra (Monniot C....
Temperate rocky reefs in the SW Atlantic are productive areas that support highly diverse communities of invertebrates, algae and fishes. Rocky outcrops form complex structures which offer a diversity microhabitats lead to great variety co-existing species. Subtidal biodiversity within Natural Protected Area Península Valdés is largely unexplored studies mainly limited fish. A total 560 high definition photoquadrats from seven (1-25 m depth) at Punta Pardelas were obtained during March 2019....
The ascidian fauna from the Southwestern Atlantic(ArgentineSea) have scarcely been studied and rarely sampled. existing scanty records are specimens collected by dredging many decades ago. During samplings in San Matias Gulf (Río Negro, Patagonia), two new Distaplia species were found. naufragii sp. nov. was subtidal zone attached to a shipwreck, while other species, fortuita found released tides sandy intertidal zone. These differ deeply each size morphology of their zooids. They represent...
