    • Further Evidence of Chromosome Abnormalities in Normal and Haploid Gynogenetic Progenies of Rainbow Trout, Oncorhynchus mykiss 

      Colihueque, Nelson; Iturra, Patricia; Díaz, Nelson F.; Veloso Martínez, Alberto (1996)
      Gynogenetic haploid progenies of rainbow trout, produced using UV light for sperm inactivation, were studied in comparison with normal progenies. In a total of 437 normal embryos, 3.5% of them showed chromosome abnormalities: ...
    • Genetic divergence in the endangeredfrog Insuetophrynus acarpicus (Anura : Leptodactylidae) 

      Méndez, Marco; Torres Pérez, Fernando; Correa, Claudio; Soto, Eduardo R.; Núñez, José; Veloso Martínez, Alberto; Armesto, Juan J. (BRITISH HERPETOL SOC, 2006-01)
      Insuetophrynus acarpicus is a poorly known frog restricted to the temperate forests of the coastal range of Chile (39 degrees 25' S, 73 degrees 10' W). Until recently, this species was known only from one type locality ...
    • Insular morphological divergence in the lizard Liolaemus pictus (Liolaemidae) 

      Vidal, Marcela A.; Veloso Martínez, Alberto; Méndez, Marco (BRILL ACADEMIC PUBLISHERS, 2006-03)
      Liolaemus pictus is a widely distributed arboreal lizard species in southern Chile. Within this species, mainland and island subspecies have been described mainly based on external morphological characters, however, their ...
    • Phylogenetic relationships of Chilean leptodactylids: a molecular approach based on mitochondrial genes 12S and 16S 

      Correa, Claudio; Veloso Martínez, Alberto; Iturra, Patricia; Méndez, Marco (SOCIEDAD BIOLGIA CHILE, 2006-12)
      Most Chilean amphibians belong to the subfamily Telmatobiinae (Anura, Leptodactylidae). Several phylogenetic studies of Leptodactylidae and Telmatobimae, based principally on morphological characters, have implicitly ...
    • Phylogeography of Rhinella spinulosa (Anura: Bufonidae) in northern Chile 

      Correa, Claudio; Pastenes, Luis; Sallaberry Ayerza, Michel; Veloso Martínez, Alberto; Méndez, Marco (BRILL ACADEMIC PUBLISHERS, 2009-07-29)
      The southern part of the Altiplano of the Andes Range is characterized by a complex hydrography, due to an intense geologic activity and the effects of the Pleistocene glaciations. This has produced a high degree of ...
    • The Population Decline and Extinction of Darwin’s Frogs 

      Soto Azat, Claudio; Valenzuela Sánchez, Andrés; Collen, Ben; Rowcliffe, J. Marcus; Veloso Martínez, Alberto; Cunningham, Andrew A. (2013)
      Darwin’s frogs (Rhinoderma darwinii and R. rufum) are two species of mouth-brooding frogs from Chile and Argentina. Here, we present evidence on the extent of declines, current distribution and conservation status of ...
