Bioindicators and Biomarkers of Environmental Pollution in the Middle-Lower Basin of the Suquía River (Córdoba, Argentina)
TLDR
Evaluating the fish species Jenynsia multidentata as a bioindicator of environmental pollution in the middle-lower basin of the Suquía River using biotransformation and antioxidant enzymes as well as gill and liver histopathology as biomarkers results in evidence of the same trend of aquatic contamination.
Redescription of the deep-sea colonial ascidian Synoicum molle (Herdman, 1886): first record since its original finding during the Challenger Expedition
TLDR
The colonial ascidian Synoicum molle (Herdman, 1886) was recorded for the first time after its original description, and 7 colonies of S. molle were collected few km from the type locality, allowing to perform a complete morphological description of this species.
Ascidian distribution provides new insights to help define the biogeographic provinces in the South American Region
TLDR
The ascidian fauna of this region is assessed for the first time to determine if the distribution of benthic sessile filter feeders corresponds to these biogeographic provinces and proposes a separation of the South American Region into three Provinces: SCH, TDF, and SAR/MAI.
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 negative
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 new
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 Mar
Ascidiacea (Chordata, Tunicata) from Uruguay (SW Atlantic): Checklist and zoogeographic considerations
TLDR
This research extends beyond the natural history of Uruguay into the social and economic history of the city and its people, using examples from the 20th Century as well as from modern times.
Morphology, genetics, and historical records support the synonymy of two ascidian species and suggest their spread throughout areas of the Southern Hemisphere
TLDR
The idea that A. humilis is a cryptogenic and neocosmopolitan species that has been transported by maritime traffic through the Southern Hemisphere, revealing frequent processes of exchange through this wide area for more than a century, is supported.
