Data from: Flight reconstruction of two European enantiornithines (Aves, Pygostylia) and the achievement of bounding flight in Early Cretaceous birds

Francisco J. Serrano, Luis M. Chiappe, Paul Palmqvist, Borja Figueirido, Jesús Marugán-Lobón & José L. Sanz
Birds today follow different aerial strategies to deal with the high costs of flapping flight. Intermittent flight, through either flap-gliding or bounding, is commonly used among small birds as a strategy to optimize aerial efficiency. The broad morphological disparity of the different lineages of Mesozoic birds suggests that a range of aerial strategies could have evolved early in avian evolution. Based on biomechanics and aerodynamic theory, this study reconstructs the flying properties of two small...

The impacts of trampling and ground disturbances on Antarctic soils

Pablo Tejedo & Tanya O'Neill
Antarctic soils are particularly vulnerable to disturbance due to their biological and physical properties and naturally slow recovery rates that are suppressed by low temperatures and sometimes low moisture availability. As most human activities are concentrated in relatively small scattered ice-free areas, the potential for adverse human impacts is great. Antarctic soils provide habitat for fauna and flora which are regionally important and, in some cases, include endemic representatives. Thus, protection of this component of...

Data from: Resource stability and geographic isolation are associated with genome divergence in western Palearctic crossbills

Thomas L. Parchman, Pim Edelaar, Kathryn Uckele, Eduardo T. Mezquida, Daniel Alonso, Joshua P. Jahner, Ron W. Summers & Craig W. Benkman
While many conifers produce annually variable seed crops, serotinous species (which hold seeds in cones for multiple years) represent unusually stable food resources for seed predators. Such stability is conducive to residency and potentially population divergence of consumers as exemplified by the Cassia crossbill (Loxia sinesciuris) in North America. We used genotyping-by-sequencing to test whether three Mediterranean subspecies of common crossbills (L. curvirostra) associated with the serotinous Aleppo pine (Pinus halepensis) were more genetically distinct...

Data from: Assessing among-lineage variability in phylogenetic imputation of functional trait datasets

Rafael Molin-Venegas, Juan Carlos Moreno-Saiz, Isabel Castro Castro, T. Jonathan Davies, Pedro R. Peres-Neto, Miguel Á. Rodriguez & Rafael Molina-Venegas
Phylogenetic imputation has recently emerged as a potentially powerful tool for predicting missing data in functional traits datasets. As such, understanding the limitations of phylogenetic modelling in predicting trait values is critical if we are to use them in subsequent analyses. Previous studies have focused on the relationship between phylogenetic signal and clade-level prediction accuracy, yet variability in prediction accuracy among individual tips of phylogenies remains largely unexplored. Here, we used simulations of trait evolution...

Data from: Wind farms affect the occurrence, abundance and population trends of small passerine birds: the case of the Dupont's lark

Julia Gómez-Catasús, Vicente Garza & Juan Traba
1.The assessment of the effects of wind farms on bird populations is commonly based on collision fatality records. This could undervalue the effect of wind farms on small-sized birds. We evaluate the effect of wind turbines on occurrence, abundance and population trends of a threatened small passerine species, the Dupont's lark Chersophilus duponti. To our knowledge, this is one of the first studies addressing the effect of wind farms on population trends using time series...
