IntroducciónEl estado de conocimiento sobre las ranas del género Eleutherodactylus de la Cordillera de Mérida (Venezuela) se encuentra aún en una fase muy preliminar. Sus especies, incluyendo la que aquí se describe como nueva, se han citado en dicha Cordillera en cinco estados. Según la recopilación de Barrio Amorós (1998), en el estado Táchira se conocen siete especies: E. anolirex Lynch, 1983, E. chlorosoma Rivero, 1984, E. lentiginosus Rivero, 1984, E. melanoproctus Rivero, 1984, E. mondolfii Rivero, 1984 RESUMENSe describe una nueva rana del género Eleutherodactylus de la Cordillera de Mérida, Andes de Venezuela. La especie se distingue del resto de congéneres por su tamaño moderado, primer dedo de la mano igual o más corto que el segundo, palmeadura pedal basal, y color dominante marrón uniforme o con pocas manchas. Se compara la especie con los grupos unistrigatus y conspicillatus, pero no se asigna a ninguno de ellos. Se presenta un mapa de distribución y un sonograma del canto. Se comenta brevemente sobre el conocimiento actual de las ranas del género Eleutherodactylus en Venezuela. Palabras clave: Anura, Leptodactylidae, Eleutherodactylus yustizi nueva especie, Cordillera de Mérida, Andes, Venezuela. ABSTRACT A new Eleutherodactylus (Anura, Leptodactylidae) from the Cordillera de Mérida, VenezuelaA new frog of the genus Eleutherodactylus is described from the Cordillera de Mérida, Venezuelan Andes. The species is distinguished from others by its moderate size, first finger equal or shorter than second, basal webbing on toes, and dominant colour immaculate brown or with a few spots. The species is compared with the groups unistrigatus and conspicillatus, but not assigned to either of them. A distribution map and a sonogram (of the song) are presented. Comments about current knowledge of frogs of the genus Eleutherodactylus in Venezuela are provided.

The olive tree (Olea europaea L.) is a species of great importance in history and economic, with large phenotypic variability, represented through a wide range of cultivars spread throughout the world. There are several studies on the characterization of a large number of cultivars of the species. However, there is a need to uncover how these phenotypic traits are heritable, and how they can change when environmental conditions vary. For this reason, the objective here was to estimate the heritability coefficients for fruit characters in six commercial cultivars, analyzed under conditions in the state of Rio Grande do Sul, Brazil. The study was carried out in a single year, based on the analysis of fruit and oil traits on the cultivars Arbequina, Arbosana, Frantoio, Koroneiki, Manzanilla de Sevilla, and Picual, under environmental conditions in the state of Rio Grande do Sul. Phenotypic plasticity and broad-sense heritability were estimated in both inter and intra-cultivar comparisons. From the analyses of variance and heritability, it was observed that some cultivars such as Koroneiki or Picual had their characters mainly under genetic control, while Arbequina was more influenced by genotype-environment interaction.The information derived from this work can help guide the selection of cultivars that are best adapted under the local environments of the southern region of Brazil.
