    • Cross-species transmission of retroviruses among domestic and wild felids in human-occupied landscapes in Chile 
      Sacristán, Irene; Acuña, Francisca; Aguilar, Emilio; García Bustos, Sebastián Aurelio; López, María José; Cabello, Javier; Hidalgo Hermoso, Ezequiel; Sanderson, Jim; Terio, Karen A.; Barrs, Vanessa; Beatty, Julia; Johnson, Warren E.; Millán, Javier; Poulin, Elie Albert; Napolitano Valenzuela, Constanza Gabriela (Wiley, 2021)
      Human transformation of natural habitats facilitates pathogen transmission between domestic and wild species. The guigna (Leopardus guigna), a small felid found in Chile, has experienced habitat loss and an increased ...
    • Genetic diversity of Rhizobium from nodulating beans grown in a variety of Mediterranean climate soils of Chile 
      Baginsky Guerrero, Cecilia; Brito, Belén; Scherson Vicencio, Rosa; Pertuze Concha, Ricardo; Seguel Seguel, Oscar; Cañete, Alejandro; Araneda Tolosa, Cristian; Johnson, Warren E. (Springer-Verlag, 2015)
      In spite of potentially being an important source of rhizobial diversity and a key determinant of common bean productivity, there is a paucity of data on Rhizobium genetic variation and species composition in the ...
    • 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 ...
    • 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 ...
    • Phylogeography and population history of Leopardus guigna, the smallest American felid 
      Napolitano, Constanza; Johnson, Warren E.; Sanderson, Jim; O’Brien, Stephen J.; Hoelzel, A. Rus; Freer, Rachel; Dunstone, Nigel; Ritland, Kermit; Ritland, Carol E.; Poulin, Elie (Springer Science+Business Media, 2014)
      The guigna (Leopardus guigna) is the smallest and most-restricted New World cat species, inhabiting only around 160,000 km2 of temperate rain forests in southern South America and is currently threatened by habitat ...
    • Reduced Genetic Diversity and Increased Dispersal in Guigna (Leopardus guigna) in Chilean Fragmented Landscapes 
      Napolitano, Constanza; Díaz, Diego; Sanderson, Jim; Johnson, Warren E.; Ritland, Kermit; Ritland, Carol E.; Poulin, Elie (Oxford Univ Press, 2015)
      Landscape fragmentation is often a major cause of species extinction as it can affect a wide variety of ecological processes. The impact of fragmentation varies among species depending on many factors, including their ...
