Molecular systematics and taxonomic status of three latitudinally widespread nototheniid (Perciformes: Notothenioidei) fishes from the Southern Ocean
(Magnolia Press, 2016)
The taxonomic status of the three nototheniids, Lepidonotothen squamifrons, L. larseni and
Gobionotothen marionensis from different localities in the Southern Ocean is re-evaluated at the
DNA level. DNA sequence divergences ...
Otolith morphology and feeding ecology of an Antarctic 3 nototheniid, Lepidonotothen larseni
(Cambridge University Press, 2013-05)
This study is based on the analysis of the stomach content and the morphology and morphometry of the three pairs of otoliths (sagitta, asteriscus and lapillus) of Lepidonotothen larseni (Lo¨nnberg) collected at the South ...
Comparative populational study of Lepidonotothen larseni and L. nudifrons (Teleostei: Nototheniidae) from the Antarctic Peninsula and the South Shetland Islands, Antarctica
(Springer, 2019-08-01)
Most Antarctic notothenioids exhibit clear geographic structure at large scales of spatial separation, generally between populations off different Ocean sectors. At smaller distances, there is great variation in the extent ...
Ontogenetic changes in the feeding strategy of Lepidonotothen nudifrons (Pisces, Nototheniidae) off the South Shetland islands and the Antarctic Peninsula
(Wiley Blackwell Publishing, Inc, 2017-06-01)
The diet and feeding strategy of Lepidonotothen nudifrons off the South Shetland Islands and the Antarctic Peninsula, as well as their variation in relation to ontogenetic stage (juvenile– adult) and sampling area, were ...
New insights into reproductive physiology in Antarctic fish: a trial in Lepidonotothen nudifrons
(Springer, 2021-06)
The spatio-temporal delimitation of fish reproduction is essential for the appropriate management and conservation strategies in populations. Assessing this feature in Antarctic Ichthyology is particularly difficult because ...
Comparative populational study of Lepidonotothen larseni and L. nudifrons (Teleostei: Nototheniidae) from the Antarctic Peninsula and the South Shetland Islands, Antarctica
(Springer, 2019-07)
Most Antarctic notothenioids exhibit clear geographic structure at large scales of spatial separation, generally between populations off different Ocean sectors. At smaller distances, there is great variation in the extent ...
New insights on reproductive features in Lepidonotothen nudifrons (Pisces, Notothenioidei) at the south Shetland Island, supported by physiological evidence
(Asociación Latinoamericana de Investigadores en Ciencias del Mar, 2019)
The Southern Ocean marine ichthyofauna is dominated by a unique costal demersal fish group, the suborder Notothenioidei. The nototheniid Lepidonotothen nudifrons is abundant in nearshore waters of the Scotia Arc region, ...

Somatic energy content and histological analysis of the gonads in Antarctic fish from the Scotia Arc
(Instituto de Ciencias del Mar Barcelona, 2005-06)
Low temperatures and highly seasonal productivity, both characteristics of the Antarctic marine environment, influence the energy budget of Antarctic fish and their reproductive timing. This study analyses the histological ...
Dietary overlap in inshore notothenioid fish from the Danco Coast, western Antarctic Peninsula
(Co-action Publishing, 2013-12)
We carried out a dietary overlap analysis between notothenioid species by examining the stomach contents of more than 900 specimens collected in a fish assemblage at the Danco Coast, western Antarctic Peninsula, in the ...
