Data from: Thorson’s rule, life history evolution and diversification of benthic octopuses (Cephalopoda: Octopodoidea)

Christian M. Ibáñez, Enrico L. Rezende, Roger D. Sepúlveda, Jorge Avaria-Llautureo, Cristián E. Hernández, Javier Sellanes, Elie Poulin & María Cecilia Pardo-Gandarillas
Here we evaluate the so-called Thorson’s rule, which posits that direct-development and larger eggs are favored towards the poles in marine organisms and whose validity been the subject of considerable debate in the literature, combining an expanded phenotypic dataset encompassing 60 species of benthic octopuses with a new molecular phylogeny. Phylogenetic reconstruction shows two clades: clade 1 including species of the families Eledonidae, Megaleledonidae, Bathypolypodidae and Enteroctopodidae, and clade 2 including species of Octopodidae. Egg...

Data from: A down-shifting Eu 3+ -doped Y 2 WO 6 /TiO 2 photoelectrode for improved light harvesting in dye-sensitized solar cells

Jaime Llanos, Ivan Brito, Dario Espinoza, Ramkumar Sekar & Paulraj Manidurai
Y1.86Eu0.14WO6 phosphors were prepared using a solid-state reaction method. Their optical properties were analysed, and they was mixed with TiO2, sintered, and used as a photoelectrode (PE) in dye-sensitized solar cells (DSSCs). The as-prepared photoelectrode was characterized by photoluminescence spectroscopy, diffuse reflectance, electrochemical impedance spectroscopy (EIS) and X-ray diffraction. The photoelectric conversion efficiency of the DSSC with TiO2:Y1.86Eu0.14WO6 (100:2.5) was 25.8% higher than that of a DSCC using pure TiO2 as PE. This high efficiency...

Data from: Interspecific geographic range size–body size relationship and the diversification dynamics of Neotropical Furnariid birds

Oscar Inostroza-Michael, Cristián E. Hernández, Enrique Rodríguez-Serrano, Jorge Avaria-Llautureo & Marcelo M. Rivadeneira
Among the earliest macroecological patterns documented, is the range and body size relationship, characterized by a minimum geographic range size imposed by the species' body size. This boundary for the geographic range size increases linearly with body size and has been proposed to have implications in lineages evolution and conservation. Nevertheless, the macroevolutionary processes involved in the origin of this boundary and its consequences on lineage diversification has been poorly explored. We evaluate the macroevolutionary...

Data from: Genetic signals of artificial and natural dispersal linked to colonization of South America by non-native Chinook salmon (Oncorhynchus tshawytscha)

Daniel Gomez-Uchida, Diego Cañas-Rojas, Carla M. Riva-Rossi, Javier E. Ciancio, Miguel A. Pascual, Billy Ernst, Eduardo Aedo, Selim S. Musleh, Francisca Valenzuela-Aguayo, Thomas P. Quinn, James E. Seeb & Lisa W. Seeb
Genetics data have provided unprecedented insights into evolutionary aspects of colonization by non-native populations. Yet, our understanding of how artificial (human-mediated) and natural dispersal pathways of non-native individuals influence genetic metrics, evolution of genetic structure, and admixture remains elusive. We capitalize on the widespread colonization of Chinook salmon Oncorhynchus tshawytscha in South America, mediated by both dispersal pathways, to address these issues using data from a panel of polymorphic SNPs. First, genetic diversity and the...

Data from: Consequences of swamp forest fragmentation on assemblages of vascular epiphytes and climbing plants: evaluation of the metacommunity structure

Jimmy Pincheira-Ulbrich, Christian E. Hernandez & Alfredo Saldaña
Aim: Habitat reduction in fragmented landscapes provides an opportunity to study the biogeographic patterns that drive changes in diversity in poorly studied metacommunities. In this study, colonization-extinction dynamics were indirectly evaluated through the analysis of the species-area relationship and the nestedness of vascular epiphytes and climbing plants in 30 swamp forest fragments. Location: Coast of the Araucanía Region in Chile. Taxon: Vascular epiphytes (16 species, mainly Pteridophytes) and climbing plants (15 species). Methods: We used...
