Accounting for relatedness and spatial structure to improve plant phenotypic selection in the wild Fontúrbel, Francisco E.; Ferrer, Pedro F.; Vega Retter, Caren; Medel Contreras, Rodrigo (Springer, 2020)Identifying natural selection in wild plant populations is a challenging task, as the reliability of selection coefficients depends, among other factors, on the critical assumption of data independence. While rarely examined, ...

Copaja Castillo, Sylvia; Mauro, Lidia; Vega Retter, Caren; Véliz Baeza, David (Soc Chilena Química, 2020)We studied the adsorption-desorption of Cu, Mn, Pb and Zn in Maipo river basin, one of the most perturbed rivers in Chile, and thus determined its tolerance to the addition of these metals into the sediments and the ...

Vega Retter, Caren; Muñoz Rojas, Pablo; Rojas Hernández, Noemí; Copaja Castillo, Sylvia; Flores Prado, Luis; Véliz Baeza, David (Wiley, 2020)The presence of a dam disturbs river flow, which in turn directly affects the communities and evolutionary potential of riverine species. To detect the ecological effects of a dam on genetic diversity, genetic structure, ...

Díaz Cabrera, Ernesto; Meerhoff, Erika; Rojas Hernández, Noemí; Vega Retter, Caren; Véliz Baeza, David (Universidad de Valparaíso, 2017)The spiny lobster Panulirus pascuensis stands out among the endemic species of Easter Island, due to its cultural and economic importance. A total of 16 microsatellite loci were characterized in 18 individuals, 9 of which ...

Fonturbel, Francisco E.; Murua, Maureen M.; Vega Retter, Caren (Springer, 2016-05)Tristerix corymbosus (Loranthaceae) is a keystone mistletoe from the South American temperate rainforests. As most mistletoes, T. corymbosus relies on biotic pollination and seed dispersal, which may cause population ...

Vega Retter, Caren; Rojas Hernández, N.; Vila Pinto, Irma; Espejo, R.; Loyola, D. E.; Copaja Castillo, Sylvia; Briones, M.; Nolte, A. W.; Véliz Baeza, David (Nature Publishing Group, 2018)How organisms adapt to unfavorable environmental conditions by means of plasticity or selection of favorable genetic variants is a central issue in evolutionary biology. In the Maipo River basin, the fish Basilichthys ...

Valencia, Evelyn; Véliz Baeza, David; Tombari, Andrea; Vega Retter, Caren (Universidad Católica de Valparaíso, 2017)The study of species in their native geographic ranges is key to understanding how human activity has influenced spatial fragmentation or species homogenization. The Argentinian silverside Odontesthes bonariensis, of ...

Copaja Castillo, Sylvia; Pérez, C. A.; Vega Retter, Caren; Véliz Baeza, David (Springer, 2017)In this study, we analyze the concentration of ten metals in two freshwater fish-the benthic catfish Trichomycterus areolatus and the limnetic silverside Basilichthys microlepidotus-in order to detect possible accumulation ...

Urquizo, Omar N.; Véliz Baeza, David; Torrico Bazoberry, Daniel; Vega Retter, Caren; Flores Prado, L.; Niemeyer Fernández, Hermann; Pinto, C.F. (Springer, 2020)Alchisme grossa is a treehopper species showing maternal care until at least the third nymphal instar. A secondary female treehopper has frequently been observed near a family (primary female guarding its egg clutch). ...

Véliz Baeza, David; Rojas Hernández, Noemi; Copaja Castillo, Sylvia; Vega Retter, Caren (Wiley, 2020)Human activity has caused a deterioration in the health and population size of riverine species; thus, public policies have been implemented to mitigate the anthropogenic impacts of water use, watercourse transformation, ...

Valencia, Evelyn; Meerhoff, Erika; Díaz Cabrera, Ernesto; Guerrero, Felipe; Roja Hernández, Noemí; Vega Retter, Caren; Véliz Baeza, David (Wiley, 2020)Population connectivity has a fundamental role in metapopulation dynamics, with important implications in conservation. Easter Island (EI) and Salas y Gomez Island (SG) in the Pacific Ocean are ideal for the study of ...
