    • Genetics, Gene Flow, and Glaciation: The Case of the South American Limpet Nacella mytilina 
      González Wevar, Claudio; Rosenfeld Sekulovic, Sebastián; Segovia Cortés, Nicolás; Hune, Mathias; Gérard, Karin; Ojeda, Jaime; Mansilla Muñoz, Andrés; Brickle, Paul; Díaz, Angie; Poulin, Elie (Public Library Science, 2016)
      Glacial episodes of the Quaternary, and particularly the Last Glacial Maximum (LGM) drastically altered the distribution of the Southern-Hemisphere biota, principally at higher latitudes. The irregular coastline of Patagonia ...
    • Global phylogeography and genetic diversity of the long-finned pilot whale Globicephala melas, with new ... 
      Kraft, Sebastian; Pérez Álvarez, María José; Olavarría, Carlos; Poulin, Elie (Nature, 2020)
      The matrilineal long-finned pilot whale presents an antitropical distribution and is divided into two subspecies, one in the temperate seas of the Southern Hemisphere and the other restricted to the North Atlantic and ...
    • Native American gene flow into Polynesia predating Easter Island settlement 
      Ioannidis, Alexander G.; Blanco Portillo, Javier; Sandoval, Karla; Hagelberg, Erika; Miquel-Poblete, Juan Francisco; Moreno Mayar, J. Víctor; Rodríguez Rodríguez, Juan Esteban; Auckland, Kathryn; Parks, Tom; Robson, Kathryn; Hill, Adrian V.

      The possibility of voyaging contact between prehistoric Polynesian and Native American populations has long intrigued researchers. Proponents have pointed to the existence of New World crops, such as the sweet potato and ...
    • Phylogeography and genetic diversity of the microbivalve kidderia subquadrata, reveals new data from West ... 
      Levicoy, Daniela; Flores, Kamila; Rosenfeld Sekulovic, Sebastián Alejandro; Cárdenas, Leyla (Nature, 2021)
      It is well established that Antarctic biodiversity has been strongly influenced by rapid climatic fluctuations during the Quaternary. Marine invertebrates from Antarctica constitute an interesting lens through which to ...
    • Pinna rapanui n. sp (Bivalvia: Pinnidae): The Largest Bivalve Species from Easter Island, South Pacific ... 
      Araya, Juan Francisco; Osorio, Cecilia (Univ Hawaii, 2016)
      A new bivalve species of the genus Pinna Linnaeus, 1758, is described from shallow water off the coast of Easter Island, southeastern Pacific Ocean. Pinna rapanui sp. n. has a small, broad, slightly angulated shell with ...
    • Spatial and temporal stability in the genetic structure of a marine crab despite a biogeographic break 
      Véliz Baeza, David Enrique; Rojas Hernández, Noemí Vaneska; Vega Retter, Caren; Zaviezo Larenas, Camila; Garrido, Ignacio; Pardo, Luis Miguel (Nature Portfolio, 2022)
      Elucidating the processes responsible for maintaining the population connectivity of marine benthic species mediated by larval dispersal remains a fundamental question in marine ecology and fishery management. Understanding ...
    • The subantarctic rayadito (aphrastura subantarctica), a new bird species on the southernmost islands of the ... 
      Rozzi, Ricardo; Quilodrán, Claudio S.; Botero Delgadillo, Esteban; Napolitano, Constanza; Torres Mura, Juan C.; Barroso, Omar; Crego, Ramiro D.; Bravo, Camila; Ippi, Silvina; Quirici, Verónica; Mackenzie, Roy; Suazo, Cristián G.; Rivero de Aguilar, Juan; Goffinet, Bernard; Kempenaers, Bart; Poulin, Elie Albert; Vásquez Salfate, Rodrigo Alfonso (Nature, 2022)
      We describe a new taxon of terrestrial bird of the genus Aphrastura (rayaditos) inhabiting the Diego Ramirez Archipelago, the southernmost point of the American continent. This archipelago is geographically isolated and ...
