    • Ancient and modern steps during the domestication of guinea pigs (Cavia porcellus L.) 
      Spotorno Oyarzún, Ángel; Marín, Juan C.; Manríquez Soto, Germán Raúl; Valladares, J. P.; Rico, E.; Rivas, C. (BLACKWELL, 2006-09)
      To test whether there are differences between living lineages of domestic guinea pigs Cavia porcellus, we studied 118 specimens from six breeds collected along six Andean countries as well as 15 from the wild cavy species ...
    • Finding of polydactyly in a free-ranging guanaco (Lama guanicoe) 
      Zapata, Beatriz; González, B. A.; Marín, Juan C.; Cabello, J. L.; Johnson, W. E.; Skewesf, O. (ELSEVIER SCIENCE BV, 2008-05)
      Polydactylism, a genetic defect characterized by partial or complete duplication of the digit, has been described in a wide range of vertebrates. Among ungulates, polydactyly appears to be relatively common in domestic ...
    • Maintenance of Genetic Diversity in an Introduced Island Population of Guanacos after Seven Decades and Two ... 
      González Pérez, Benito Alejandro; Orozco-terWengel, Pablo; Von Borries, Rainer; Johnson, Warren E.; Franklin, William L.; Marín, Juan C. (2014)
      Fifteen guanacos were introduced to Staats Island in the Falklands/Malvinas archipelago from Patagonia in the 1930s. Twenty five years later, the population was culled from 300 to 10–20 individuals, but quickly rebounded ...
    • Mitochondrial phylogeography and demographic history of the Vicuna: implications for conservation 
      Marín, Juan C.; Casey, C. S.; Kadwell, M.; Yaya, K.; Hoces, D.; Olazabal, J.; Rosadio, R.; Rodríguez, J.; Spotorno Oyarzún, Ángel; Bruford, Michael W.; Wheeler, Jane C. (2007)
      The vicuna (Vicugna vicugna; Miller, 1924) is a conservation success story, having recovered from near extinction in the 1960s to current population levels estimated at 275 000. However, lack of information about its ...
    • Molecular diversity among domestic guinea-pigs (Cavia porcellus) and their close phylogenetic relationship ... 
      Spotorno Oyarzún, Ángel; Valladares, John P.; Marín, Juan C.; Zeballos, Horacio (SOCIEDAD BIOLGIA CHILE, 2004-06)
      To investigate the origin and diversity of domestic guinea-pigs Cavia porcellus (Linnaeus, 1758; Rodentia, Caviidae), we sequenced the mitochondrial cytochrome b gene of 12 domestic and 10 wild specimens from six species, ...
    • Past and recent effects of livestock activity on the genetic diversity and population structure of native ... 
      Mesas, Andrés; Baldi, Ricardo; González Pérez, Benito Alejandro; Burgi, Virginia; Chávez, Alexandra; Johnson, Warren E.; Marín, Juan C. (MDPI, 2021)
      Extensive livestock production and urbanization entail modifications of natural landscapes, including installation of fences, development of agriculture, urbanization of natural areas, and construction of roads and ...
