The humboldt current system of northern and central chile : Oceanographic processes, ecological interactions and socioeconomic feedback
TLDR
Interestingly, El Nino events in northern Chile do not appear to cause a dramatic decline in primary or zooplankton production but rather a shift in species composition, which affects trophic efficiency of and interactions among higher-level consumers. Expand
Avoiding offshore transport of competent larvae during upwelling events: The case of the gastropod Concholepas concholepas in Central Chile
TLDR
The retention of C. concholepas competent larvae in the upwelled waters could be the result of the interaction between their reverse diel vertical migration and the typical two-layer upwelling dynamics. Expand
Origin, diversification, and historical biogeography of the genus Trachurus (Perciformes: Carangidae).
TLDR
The phylogeny based on Cyt b, supports the molecular clock hypothesis and results agree with the reported fossil indicating that the origin of this genus occur when the Thetys Sea closed (around 18.4 MYA). Expand
Ecological and biogeographical inferences on two sympatric and enigmatic Andean cat species using genetic identification of faecal samples
TLDR
This work determined the origin of 186 carnivore samples collected above 3000 m above sea level in northern Chile, including 33 from the Andean mountain cat and 75 from the pampas cat using diagnostic molecular genetic sequence variation, suggesting low levels of prey partitioning between species. Expand
Evolutionary versus ecological success in Antarctic benthic invertebrates
TLDR
It is argued that the present shallow Antarctic benthic invertebrate fauna is the result of two processes acting at different temporal scales: species-level selection occurring over geological and evolutionary times and processes associated with the advantage of having pelagic larvae under highly disturbed conditions. Expand
Molecular phylogeny and historical biogeography of Nacella (Patellogastropoda: Nacellidae) in the Southern Ocean.
TLDR
The origin and diversification of Nacella in the Southern Ocean is more recent than expected under the hypothesis of vicariant speciation due to plate tectonics and the absence of genetic divergence among these species supports a very recent radiation process accompanied by rapid morphological and ecological diversification. Expand
Phylogeography and demographic inference in Nacella (Patinigera) concinna (Strebel, 1908) in the western Antarctic Peninsula
TLDR
Genetic similarities between South Georgia and Antarctic samples, as well as between Nacella delesserti and the Antarctic limpet, could be explained through north-eastward long-distance dispersion events during the late Pleistocene. Expand
Genetic population structure in the Chilean jack mackerel, Trachurus murphyi (Nichols) across the South-eastern Pacific Ocean
TLDR
The present results did not support the existence of different stock units for T. murphyi across the South Pacific Ocean but a more holistic approach will be necessary to determine an adequate management strategy for this fishery. Expand
Marked phylogeographic structure of Gentoo penguin reveals an ongoing diversification process along the Southern Ocean.
TLDR
The APF appears to be a significant biogeographical boundary for Gentoo penguin populations; however, the ACC does not promote connectivity in this species, and data suggest demographic expansion in the WAP during the last glacial maximum, but stability in SAI. Expand
Phylogeographic Structure in Benthic Marine Invertebrates of the Southeast Pacific Coast of Chile with Differing Dispersal Potential
TLDR
Historic processes have led to the current biogeographic and phylogeographic structure of marine species with limited dispersal along the north-central coast of Chile, with a strong lasting impact in their genetic structure. Expand
