Data from: Artificial light at night confounds broad-scale habitat use by migrating birds

With many of the world's migratory bird populations in alarming decline, broad-scale assessments of responses to migratory hazards may prove crucial to successful conservation efforts. Most birds migrate at night through increasingly light-polluted skies. Bright light sources can attract airborne migrants and lead to collisions with structures, but might also influence selection of migratory stopover habitat and thereby acquisition of food resources. We demonstrate, using multi-year weather radar measurements of nocturnal migrants across the northeastern...

Data from: Biodiverse cities: the nursery industry, homeowners, and neighborhood differences drive urban tree composition

In arid and semi-arid regions, where few if any trees are native, city trees are largely human-planted. Societal factors such as resident preferences for tree traits, nursery offerings, and neighborhood characteristics are potentially key drivers of urban tree community composition and diversity, however they remain critically understudied. We investigated patterns of urban tree structure in residential neighborhoods of the Salt Lake Valley, Utah, combining biological variables, such as neighborhood and plant nursery tree species and...

Data from: Using greenhouse gas fluxes to define soil functional types

Sandra Petrakis, Josep Barba, Benjamin Bond-Lamberty & Rodrigo Vargas
Aim: Soils provide key ecosystem services and directly control ecosystem functions; thus, there is a need to define the reference state of soil functionality. Most common functional classifications are vegetation-centered, such as plant functional types (PFTs), and neglect soil characteristics and processes. We propose Soil Functional Types (SFTs) as a conceptual approach to represent and describe the functionality of soils based on characteristics of their greenhouse gas (GHG) flux dynamics. Methods: We used automated measurements...

Data from: Quantifying the importance of geographic replication and representativeness when estimating demographic rates, using a coastal species as a case study

Christopher R. Field, Katharine J. Ruskin, Bri Benvenuti, Alyssa C. Borowske, Jonathan B. Cohen, Laura Garey, Thomas P. Hodgman, Rebecca A. Kern, Erin King, Alison R. Kocek, Adrienne I. Kovach, Kathleen M. O'Brien, Brian J. Olsen, Nancy Pau, Samuel G. Roberts, Emma Shelly, W. Gregory Shriver, Jennifer Walsh, Chris S. Elphick & Rebecca A. Longenecker
Demographic rates are rarely estimated over an entire species range, limiting empirical tests of ecological patterns and theories, and raising questions about the representativeness of studies that use data from a small part of a range. The uncertainty that results from using demographic rates from just a few sites is especially pervasive in population projections, which are critical for a wide range of questions in ecology and conservation. We developed a simple simulation to quantify...

Data from: Subspecies delineation amid phenotypic, geographic, and genetic discordance in a songbird

Jennifer Walsh, Irby J. Lovette, Virginia Winder, Chris S. Elphick, Brian J. Olsen, W. Gregory Shriver, Adrienne I. Kovach & Gregory Shriver
Understanding the processes that drive divergence within and among species is a long-standing goal in evolutionary biology. Traditional approaches to assessing differentiation rely on phenotypes to identify intra- and interspecific variation, but many species express subtle morphological gradients in which boundaries among forms are unclear. This intraspecific variation may be driven by differential adaptation to local conditions and may thereby reflect the evolutionary potential within a species. Here, we combine genetic and morphological data to...
