The biology of Mustelus schmitti in southern Patagonia, Argentina
(Wiley Blackwell Publishing, Inc, 2000-12)
The relationship of body weight and total length (L(T)) of Mustelus schmitti in southern Patagonia was different between sexes. Changes in maturity stages in males appear at larger sizes in Ria Deseado specimens than in ...
Proximate composition and energy value of demersal and pelagic prey species from Southwest Atlantic
(Inter-Research, 2005-12)
This study describes the proximate composition (moisture, lipid, protein and ash content) and energetic value of 39 species (27 teleosts, 3 sharks, 7 rays and 2 squids) that are known as key prey or potential prey of top ...
Altimeter-derived seasonal circulation on the southwest Atlantic shelf: 27°?43°S
(American Geophysical Union, 2015-05)
Altimeter sea surface height (SSH) fields are analyzed to define and discuss the seasonal circulation over the wide continental shelf in the SW Atlantic Ocean (27°–43°S) during 2001–2012. Seasonal variability is low south ...
High density of the alien bryozoan Fenestrulina delicia in the fouling assemblage of a South American harbour (Argentina)
(Springer, 2016-06)
The non-indigenous cheilostome bryozoan Fenestrulina delicia Winston, Hayward and Craig has been recorded for the first time in the southern hemisphere. It was found on experimental substrata submersed to study the fouling ...
Reproductive biology of the southern thorny skate Amblyraja doellojuradoi (Chondrichthyes, Rajidae)
(Wiley Blackwell Publishing, Inc, 2016-04)
The total lengths (LT) of 193 males (209-556mm) and 130 females (275-515mm) of Amblyraja doellojuradoi, a commercial by-catch species on the Argentinean continental shelf, which are increasingly retained, were analysed. ...
Spatio-temporal overlap between the at-sea distribution of Southern Giant Petrels and fisheries at the Patagonian Shelf
(Springer, 2009-08)
The interactions between seabirds and fisheries pose significant threats for the seabird species such as incidental capture. In contrast, several species of seabirds meet part of their energetic requirements through the ...
The southernmost range limit for the hidden angelshark Squatina occulta
(BioMed Central, 2016-08)
Background: Angelsharks (Genus Squatina) are distributed in the southern Southwest Atlantic Ocean between southeastern Brazil and central Patagonia. The endangered hidden angelshark Squatina occulta is reported in the ...
Stable isotopes indicate population structuring in the southwest Atlantic population of right whales (Eubalaena australis)
(Public Library of Science, 2014-06-09)
From the early 17th century to the 1970s southern right whales, Eubalaena australis, were subject to intense exploitation along the Atlantic coast of South America. Catches along this coast recorded by whalers originally ...
