A framework for understanding climate change impacts through non-compensatory intra- and interspecific climate change responses Open
Understanding and predicting population responses to climate change is a crucial challenge. A key component of population responses to climate change are cases in which focal biological rates (e.g. population growth rates) change in respon…
A framework for understanding climate change impacts through non‐compensatory intra‐ and interspecific climate change responses Open
Understanding and predicting population responses to climate change is a crucial challenge. A key component of population responses to climate change are cases in which focal biological rates (e.g., population growth rates) change in respo…
A framework for understanding climate change impacts through intra- and interspecific asymmetries in climate change responses Open
A crucial challenge in ecology is understanding and predicting population responses to climate change. A key component of population responses to climate change are asymmetries in which focal intra- or interspecific rates (e.g. population …
Studying individual-level interactions can transform our understanding of avian mixed-species flocks Open
Avian mixed-species flocks are ubiquitous across habitats and a model for studying how heterospecific sociality influences the behavior and composition of animal communities. Here, we review the literature on mixed-species flocks and argue…
Ecogeography of group size suggests differences in drivers of sociality among cooperatively breeding fairywrens Open
Cooperatively breeding species exhibit a range of social behaviours associated with different costs and benefits to group living, often in association with different environmental conditions. For example, recent phylogenetic studies have c…
Ecological flexibility and selectivity in mixed-species flock participation in birds Open
Mixed-species groups are hypothesized to allow animals to minimize competitive interactions and maximize facilitative interactions. Individuals’ participation in mixed-species groups may reduce rates of competition and increase the social …
Sex role similarity and sexual selection predict male and female song elaboration and dimorphism in fairy‐wrens Open
Historically, bird song complexity was thought to evolve primarily through sexual selection on males; yet, in many species, both sexes sing and selection pressure on both sexes may be broader. Previous research suggests competition for mat…
Constructing social networks from automated telemetry data: A worked example using within‐ and across‐group associations in cooperatively breeding birds Open
Advances in data‐logging technologies have provided a way to monitor the movement of individual animals at unprecedented spatial and temporal scales. When used in conjunction with social network analyses, these data can provide deep insigh…
Sex role similarity and sexual selection predict male and female song elaboration and dimorphism in fairy-wrens Open
Historically, bird song complexity was thought to evolve primarily through sexual selection on males, yet in many species both sexes sing. Previous research suggests competition for mates and resources during short, synchronous breeding se…
Workflow for constructing social networks from automated telemetry systems Open
1. Advances in datalogging technologies have provided a way to monitor the movement of individual animals at unprecedented spatial and temporal scales, both large and small. When used in conjunction with social network analyses, these data…
Invited Commentaries on Shizuka & Johnson 2020, & Response from the Authors Open
Adriana A. Maldonado-Chaparro and Damien R. Farine, Demographic processes in animal networks are a question of time Amiyaal Ilany, Complex societies, simple processes Orr Spiegel and Noa Pinter-Wollman, Placing the effects of demography on…
How demographic processes shape animal social networks Open
Demographic processes play a key role in shaping the patterns of social relations among individuals in a population. Social network analysis is a powerful quantitative tool for assessing the social structure formed by associations between …
Song recognition and heterospecific associations between 2 fairy-wren species (Maluridae) Open
Interactions between species can be beneficial to one or both species and such interactions may be facilitated by recognition of group members. Splendid and variegated fairy-wrens often share overlapping, co-defended territories. We show f…

Motor, cognitive, and functional declines contribute to a single progressive factor in early HD Open
Use of a composite motor, cognitive, and global functional clinical outcome measure in HD provides an improved measure of clinical progression more related to measures of progressive brain atrophy and provides an opportunity for enhanced c…
Multiple hypotheses explain variation in extra‐pair paternity at different levels in a single bird family Open
Extra‐pair paternity ( EPP ), where offspring are sired by a male other than the social male, varies enormously both within and among species. Trying to explain this variation has proved difficult because the majority of the interspecific …
Convergent evolution in social swallows (Aves: Hirundinidae) Open
Behavioral shifts can initiate morphological evolution by pushing lineages into new adaptive zones. This has primarily been examined in ecological behaviors, such as foraging, but social behaviors may also alter morphology. Swallows and ma…
Evolution and Sociality in Fairy-wrens (Aves: Maluridae) Open
The evolution of social behavior has long been a focus of research for behavioral ecologists and evolutionary biologists. From brief interactions to highly complex associations between individuals of cooperative or colonial species, unders…
