Parental care and reproductive strategies in notothenioid fishes
(Wiley Blackwell Publishing, Inc, 2021-03-03)
The adoption of parental care behaviours is the distinctive reproductive characteristic associated with the diversification and divergence of notothenioid fishes into an array of habitats in the subzero shelf and upper ...
Detection of lamprey in Southernmost South America by environmental DNA (eDNA) and molecular evidence for a new species
(Springer, 2020-03)
Lampreys are jawless fishes belonging to the order Petromyzontiformes. Geotria australis is the sole representative lamprey species of the Geotriidae family and is widely distributed around South America, Australia, New ...
Temperature influence on post-prandial metabolic rate of Sub-Antartic teleost fish
(Elsevier Inc, 2010-06)
The influence of temperature on the aerobic metabolism and the energetic cost of food intake (Specific Dynamic Action; SDA) have been investigated in four species of Sub-Antarctic teleosts. The species were the notothenioids ...
Effects on the metabolism, growth, digestive capacity and osmoregulation of juvenile of Sub-Antarctic Notothenioid fish Eleginops maclovinus acclimated at different salinities
(2015)
In this study we assessed the influence of three different environmental salinities (5, 15 and 31 psu during 90 days) on growth, osmoregulation, energy metabolism and digestive capacity in juveniles of the Notothenioid ...
Combined effects of high stocking density and Piscirickettsia salmonis treatment on the immune system, metabolism and osmoregulatory responses of the Sub-Antarctic Notothenioid fish Eleginops maclovinus
(2014)
The aim of this study was to evaluate immunological, metabolic and osmoregulatory secondary stress responses in Eleginops maclovinus specimens submitted to three different stocking densities: i) low (3.1 kg m−3), medium ...
The right tool for the right question: contrasting biogeographic patterns in the notothenioid fish Harpagifer spp. along the Magellan Province
(Royal Soc., 2022)
Molecular-based analysis has become a fundamental tool to understand the role of Quaternary glacial episodes. In the Magellan Province in southern South America, ice covering during the last glacial maximum (20 ka) radically ...
Shags in Antarctica: their feeding behaviour and ecological role in the marine food web
(Cambridge University Press, 2006-03)
Feeding behaviour, ecological role in the marine food web and population trends of the Antarctic shag Phalacrocorax bransfieldensis and the South Georgia shag P. georgianus in Antarctica are analysed. The diving depths and ...
The hemoglobins of the sub-Antarctic fish Cottoperca gobio, a phyletically basal species - Oxygen-binding equilibria, kinetics and molecular dynamics
(Wiley Blackwell Publishing, Inc, 2009-04)
The dominant perciform suborder Notothenioidei is an excellent study group for assessing the evolution and functional importance of biochemical adaptations to temperature. The availability of notothenioid taxa in a wide ...
Effects of temperature on the innate immune response on Antarctic and sub-Antarctic fish Harpagifer antarcticus and Harpagifer bispinis challenged with two immunostimulants, LPS and Poly I:C : In vivo and in vitro approach
(2022-11)
Rising ocean temperatures due to climate change combined with the intensification of anthropogenic activity can drive shifts in the geographic distribution of species, with the risks of introducing new diseases. In a ...
