Data from: Influence of landscape features on the microgeographic genetic structure of a resident songbird.

Rachael V. Adams, Stefanie E. LaZerte, Ken A. Otter & Theresa M. Burg
Landscape features influence individual dispersal and as a result can affect both gene flow and genetic variation within and between populations. The landscape of British Columbia, Canada, is already highly heterogeneous due to natural ecological and geological transitions, but disturbance from human-mediated processes has further fragmented continuous habitat, particularly in the central plateau region. In this study, we evaluated the effects of landscape heterogeneity on the genetic structure of a common resident songbird, the black-capped...

Data from: A multigenerational effect of parental age on offspring size but not fitness in common duckweed (Lemna minor)

Patrick M. Barks & Robert A. Laird
Classic theories on the evolution of senescence make the simplifying assumption that all offspring are of equal quality, so that demographic senescence only manifests through declining rates of survival or fecundity. However, there is now evidence that, in addition to declining rates of survival and fecundity, many organisms are subject to age-related declines in the quality of offspring produced (i.e. parental age effects). Recent modelling approaches allow for the incorporation of parental age effects into...

Data from: Sexual selection on male vocal fundamental frequency in humans and other anthropoids

Jablonski, Mark D. Shriver, Daniel J. Weiss, Adriano R. Lameira, Coren L. Apicella, Michael J. Owren, Claudia Barelli, Mary E. Glenn & Gabriel Ramos-Fernandez
In many primates, including humans, the vocalizations of males and females differ dramatically, with male vocalizations and vocal anatomy often seeming to exaggerate apparent body size. These traits may be favoured by sexual selection because low-frequency male vocalizations intimidate rivals and/or attract females, but this hypothesis has not been systematically tested across primates, nor is it clear why competitors and potential mates should attend to vocalization frequencies. Here we show across anthropoids that sexual dimorphism...

Data from: Bud phenology and growth are subject to divergent selection across a latitudinal gradient in Populus angustifolia and impact adaptation across the distributional range and associated arthropods

Luke M. Evans, Sobadini Kaluthota, David W. Pearce, Gerard J. Allan, Kevin Floate, Stewart B. Rood & Thomas G. Whitham
Temperate forest tree species that span large geographical areas and climatic gradients often have high levels of genetic variation. Such species are ideal for testing how neutral demographic factors and climate-driven selection structure genetic variation within species, and how this genetic variation can affect ecological communities. Here, we quantified genetic variation in vegetative phenology and growth traits in narrowleaf cottonwood, Populus angustifolia, using three common gardens planted with genotypes originating from source populations spanning the...

Data from: Direction matching for sparse movement data sets: determining interaction rules in social groups

Tyler R. Bonnell, S. Peter Henzi & Louise Barrett
It is generally assumed that high-resolution movement data are needed to extract meaningful decision-making patterns of animals on the move. Here we propose a modified version of force matching (referred to here as direction matching), whereby sparse movement data (i.e., collected over minutes instead of seconds) can be used to test hypothesized forces acting on a focal animal based on their ability to explain observed movement. We first test the direction matching approach using simulated...

Data from: Transcontinental latitudinal variation in song performance and complexity in House Wrens (Troglodytes aedon)

Chinthaka Kaluthota, Benjamin E. Brinkman, Ednei B. Dos Santos & Drew Rendall
There is growing interest in latitudinal effects on animal behavior and life-history. One recent focus is on birdsong which is hypothesized to be more elaborated or complex in the north temperate zone compared to the tropics. Current evidence is mixed and based on cross-species comparisons, or single species with restricted distributions. We circumvent these limitations using a transcontinental sample of 358 songs from House Wrens (Troglodytes aedon) at 281 locations spanning more than 100O of...
