Data from: Variation in fine-scale genetic structure and local dispersal patterns between peripheral populations of a South American passerine birdEsteban Botero-Delgadillo, Verónica Quirici, Yanina Poblete, Élfego Cuevas, Sylvia Kuhn, Alexander Girg, Kim Teltscher, Elie Poulin, Bart Kempenaers & Rodrigo A. Vasquez
The distribution of suitable habitat influences natal and breeding dispersal at small spatial scales, resulting in strong micro-geographic genetic structure. Although environmental variation can promote inter-population differences in dispersal behavior and local spatial patterns, the effects of distinct ecological conditions on within-species variation in dispersal strategies and in fine-scale genetic structure remain poorly understood. We studied local dispersal and fine-scale genetic structure in the thorn-tailed rayadito (Aphrastura spinicauda), a South American bird that breeds along...
Data from: Resolving the Northern Hemisphere source region for the long-distance dispersal event that gave rise to the South American endemic dung moss Tetraplodon fuegianusLily Lewis, Elisabeth M. Biersma, Sarah B. Carey, Kent Holsinger, Stuart F. McDaniel, Ricardo Rozzi, Bernard Goffinet & Lily R. Lewis
Premise of the study—American bipolar plant distributions characterize taxa at various taxonomic ranks but are most common in the bryophytes at infraspecific and infrageneric levels. A previous study on the bipolar disjunction in the dung moss genus Tetraplodon found that direct long-distance dispersal from North to South in the Miocene - Pleistocene accounted for the origin of the Southern American endemic Tetraplodon fuegianus, congruent with other molecular studies on bipolar bryophytes. The previous study, however,...
Data from: Plastic responses contribute to explaining altitudinal and temporal variation in potential flower longevity in high Andean Rhodolirion montanumDiego Andrés Pacheco, Leah S. Dudley, Josefina Cabezas, Lohengrin A. Cavieres & Mary T. K. Arroyo
The tendency for flower longevity to increase with altitude is believed by many alpine ecologists to play an important role in compensating for low pollination rates at high altitudes due to cold and variable weather conditions. However, current studies documenting an altitudinal increase in flower longevity in the alpine habitat derive principally from studies on open-pollinated flowers where lower pollinator visitation rates at higher altitudes will tend to lead to flower senescence later in the...
Inducible, anti-predator traits are a classic example of phenotypic plasticity. Their evolutionary dynamics depend on their genetic basis, the historical pattern of predation risk that populations have experienced and current selection gradients. When populations experience predators with contrasting hunting strategies and size preferences, theory suggests contrasting micro-evolutionary responses to selection. Daphnia pulex is an ideal species to explore the micro-evolutionary response of anti-predator traits because they face heterogeneous predation regimes, sometimes experiencing only invertebrate midge...
Data from: Lineage divergence, local adaptation across a biogeographic break, and artificial transport, shape the genetic structure in the ascidian Pyura chilensisNicolás I. Segovia, Cristian Gallardo-Escárate, Elie Poulin & Pilar A. Haye
Marine benthic organisms inhabit a heterogeneous environment in which connectivity between populations occurs mainly through dispersive larval stages, while local selective pressures acting on early life history stages lead to non-random mortality, shaping adaptive genetic structure. In order to test the influence of local adaptation and neutral processes in a marine benthic species with low dispersal, in this study we used Genotyping by Sequencing technology to compare the neutral and putatively selected signals (neutral and...
Data from: Early life experience drives short-term acclimation of metabolic and osmoregulatory traits in the leaf-eared mouseGrisel Cavieres, Monica Nuñez-Villegas, Francisco Bozinovic & Pablo Sabat
We studied the putative effect of early experience on the physiological flexibility of metabolic and osmoregulatory traits in the leaf-eared mouse Phyllotis darwini, an altricial rodent inhabiting seasonal mediterranean environments. Adult individuals were collected in central Chile and maintained in breeding pairs. Pups were isolated after weaning and acclimated to different temperature (cold or warm) and water availability (unrestricted and restricted) until adulthood. Subsequently, individuals were re-acclimated to the opposite treatment. Rodents reared in warm...
