Ruiz, Juan Francisco; Sepúlveda, Roger D.; Ibáñez, Christian M. (2012)Cephalopods have two main defence strategies: the first consists on reducing the odds of being detected by a predator, while the second focuses on avoiding capture. The aim of this study was to understand the basic behavioural ...

Pardo Gandarillas, María Cecilia; Ibáñez, Christian M.; Yamashiro, Carmen; Méndez, Marco; Poulin, Elie (Springer, 2018)Climatic and oceanographic events occurring during the last glacial cycle in the Humboldt Current System (HCS) have left genetic footprints in marine invertebrate populations. The objective of this study was to evaluate ...

Ibáñez Carvajal, Christian; Chong Lay-Son, Javier (Cambridge University Press, 2008)In this research we studied the diet of Enteroctopus megalocyathus from three principal locations of the octopus fishery (Ancud, Quellón and Melinka) in southern Chile. The gastric contents of 523 individuals, collected ...

Navarrete, Arturo H.; Sellanes, Javier; Pardo Gandarillas, M. Cecilia; Sirenko, Boris; Eernisse, Douglas J.; Camus, Patricio A.; Ojeda, F. Patricio; Ibáñez, Christian M. (Springer, 2020)Latitudinal diversity patterns in marine species are commonly estimated from literature records, which at times are incomplete and/or biased. Advances in molecular phylogenetics have contributed to avoid this bias, clarifying ...

Ibáñez, Christian M.; Pardo Gandarillas, María Cecilia; Peña, Fabiola; Gleadall, Ian G.; Poulin, Elie; Sellanes, Javier (Wiley-Blackwell, 2016)Deep-sea octopuses of the genus Muusoctopus are thought to have originated in the Pacific Northern Hemisphere and then diversified throughout the Pacific and into the rest of the World Ocean. However, this hypothesis was ...

Pardo Gandarillas, María Cecilia; Ibáñez, Christian M.; Torres, Felipe I.; Sanhueza, Víctor; Fabres, Alejandra; Escobar Dodero, Joaquín; Mardones, Fernando O.; Méndez, Marco (Blackwell Publishing Ltd, 2018)© 2018 John Wiley & Sons Ltd Aim: The distribution and genetic composition of marine populations is the result of climatic and oceanographic factors as well as life history strategies. Studying species with wide distributions ...

Ibáñez, Christian M.; Argüelles, Juan; Yamashiro, Carmen; Adasme, Luis; Céspedes, Renato; Poulin, Elie (2012)Doryteuthis gahi is a small squid species that has a wide distribution in South America. This species is characterized by coastal and benthic spawning, and its ontogenetic vertical migration is associated with upwelling ...

Ibáñez, Christian M.; Rezende, Enrico; Sepúlveda, Roger D.; Avaria Llautureo, Jorge; Hernández, Cristián E.; Sellanes, Javier; Poulin, Elie; Pardo Gandarillas, María Cecilia (Society for the Study of Evolution, 2018)Here, we evaluate the so-called Thorson’s rule, which posits that direct-development and larger eggs are favored toward the poles in marine organisms and whose validity been the subject of considerable debate in the ...

Pardo Gandarillas, María Cecilia; Torres Sánchez, Felipe; Fuchs, Dirk; Ibáñez, Christian M. (Elsevier, 2018)Two types of spawning strategy have been described for ommastrephid squids: coastal and oceanic. It has been suggested that ancestral ommastrephids inhabited coastal waters and expanded their distribution into the open ...
