Data from: Effects of grazing intensity on plant richness and diversity: a meta-analysis

Cristina Herrero-Jáuregui & Martin Oesterheld
Most of our knowledge of the effect of grazing on grassland structure is based on grazed-ungrazed contrasts. The effects of grazing in the most common scenario, where grazing intensity varies from low to high grazing intensity, are less known. The objectives of this paper were to (1) quantify the effect of stocking rates on species richness and diversity of grasslands world-wide, and (2) evaluate the response under different environmental and experimental conditions. We conducted a...

Data from: Where to start? development of a spatial tool to prioritise retrofitting of power line poles that are dangerous to raptors

Ricardo Enrique Hernandez-Lambraño, José Ángel Sánchez-Agudo & Roberto Carbonell
1.Avian electrocution on power lines is a major conservation issue on a global scale. Electrocution risk models have recently been proposed as an effective alternative to prioritising high‐risk pole retrofitting activities at a large scale. However, existing models ignore the specific features of the power poles supporting the power distribution lines and make the tenuous assumption that pole density and power line length are key factors to assessing the electrocution risk at a large scale....

Data from: Factors associated with leucism in the common blackbird (Turdus merula)

Lucía Izquierdo, Robert L. Thomson, José I. Aguirre, Alazne Díez-Fernández, Bruno Faivre, Jordi Figuerola & Juan Diego Ibáñez-Álamo
Leucism is the total or partial lack of melanins in the skin and associate structures (i.e. hair or feathers). Little is known about the factors influencing this chromatic aberration although some local studies suggest that there is an effect of habitat, age and sex. To test these hypotheses and expand our knowledge on leucism, we carried out a large‐scale study using common blackbirds (Turdus merula) as our model species. Given the poor information available on...

Data from: Genome-wide signals of drift and local adaptation during rapid lineage divergence in a songbird

Guillermo Friis, Guillermo Fandos, Amanda J. Zellmer, John E. McCormack, Brant C. Faircloth & Borja Milá
The formation of independent evolutionary lineages involves neutral and selective factors, and understanding their relative roles in population divergence is a fundamental goal of speciation research. Correlations between allele frequencies and environmental variability can reveal the role of selection, yet the relative contribution of drift can be difficult to establish. Recently diversified taxa like the Oregon junco (Aves, Passerellidae, Junco hyemalis oreganus) of western North America provide ideal scenarios to apply genetic-environment association analyses (GEA)...
