Maturana, Claudia S.; Moreno, Rodrigo A.; Labra, Fabio A.; González Wevar, Claudio; Rozbaczylo, Nicolás; Carrasco, Franklin D.; Poulin, Elie (Universidad de Valparaiso, 2011)Accurate species identification remains a basic first step in any study of biodiversity, particularly for global changes and their consequences. Thus, there is a pressing need for taxonomic expertise in a broad range of ...

Maturana Bobadilla, Claudia; Segovia Cortés, Nicolás; González Wevar, Claudio; Díaz, Angie; Rosenfeld Sekulovic, Sebastián; Poulin, Elie; Jackson, Jennifer A.; Convey, Peter (Wiley, 2020)Environmental conditions were particularly severe during the Last Glacial Maximum, altering the distribution of the Southern Hemisphere biota, particularly at higher latitudes. The copepodBoeckella poppeiis the only ...

Suárez Villota, Elkin; González Wevar, Claudio; Gallardo, Milton; Vásquez Salfate, Rodrigo; Poulin, Elie (Academic Press-Elsevier, 2016)Endemic to South America, octodontid rodents are remarkable by being the only mammal taxa where allotetraploidy has been documented. The taxon's extensive morpho-physiological radiation associated to niche shifts has allowed ...

Díaz, Angie; Gerard, Karin; González Wevar, Claudio; Maturana, C.; Ferai, Jean Pierre; David, Bruno; Saucede, Thomas; Poulin, Elie (Public Library Science, 2018-06)One of the most relevant characteristics of the extant Southern Ocean fauna is its resiliency to survive glacial processes of the Quaternary. These climatic events produced catastrophic habitat reductions and forced some ...

Ruiz Jarabo, Ignacio; González Wevar, Claudio; Oyarzún, Ricardo; Fuentes, Juan; Poulin, Elie; Beltrán, Carlos; Vargas Chacoff, Luis (Public Library Science, 2016)Background Marine species have colonized extreme environments during evolution such as freshwater habitats. The amphidromous teleost fish, Galaxias maculatus is found mainly migrating between estuaries and rivers, but ...

Ocaranza Barrera, Paula; González Wevar, Claudio; Guillemin, Marie-Laure; Rosenfeld, Sebastián; Mansilla, Andrés (Springer Netherlands, 2019)The distribution of the Southern Ocean (SO) biota is the result of major geological, oceanographic, and climate changes during the last 50 million years (Ma). Several groups of marine benthic organisms exhibit marked ...

Fernández Iriarte, P. J.; González Wevar, Claudio; Segovia, N. I.; Rosenfeld, S.; Hüne, Mathias; Fainburg, L.; Nuñez, J. D.; Haye, P. A.; Poulin, Elie (Nature, 2020)The southern coastline of South America is a remarkable area to evaluate how Quaternary glacial processes impacted the demography of the near-shore marine biota. Here we present new phylogeographic analyses in the pulmonate ...

Segovia, Nicolás I.; González Wevar, Claudio; Haye, Pilar A. (Nature Publishing Group, 2020)The highly heterogeneous Humboldt Current System (HCS) and the 30 degrees S transition zone on the southeast Pacific coast, represent an ideal scenario to test the influence of the environment on the spatial genomic structure ...
