1) Animals are expected to be judicious in the use of the energy they gain due to the costs and limits associated with its intake. The management of energy expenditure (EE) exhibited by animals has previously been considered in terms of three patterns: the constrained, independent and performance patterns of energy management. These patterns can be interpreted by regressing daily EE against maintenance EE measured over extended periods. From the multiple studies on this topic,...

Data from: Competition for mates and the improvement of nonsexual fitness

Li Yun, Patrick J. Chen, Kevin E. Kwok, Christopher S. Angell, Howard D. Rundle & Aneil F. Agrawal
Competition for mates can be a major source of selection, not just on secondary sexual traits but across the genome. Mate competition strengthens selection on males via sexual selection, which typically favours healthy, vigorous individuals and, thus, all genetic variants that increase overall quality. However, recent studies suggest another major effect of mate competition that could influence genome-wide selection: sexual harassment by males can drastically weaken selection on quality in females. Because of these conflicting...

Data from: Integration and modularity of teleostean pectoral fin shape and its role in the diversification of acanthomorph fishes

Trina Y. Du, Sylvie C. Tissandier & Hans C. E. Larsson
Phenotypic integration and modularity describe the strength and pattern of interdependencies between traits. Integration and modularity have been proposed to influence the trajectory of evolution, either acting as constraints or facilitators. Here, we examine trends in the integration and modularity of pectoral fin morphology in teleost fishes using geometric morphometrics. We compare the fin shapes of the highly diverse radiation of acanthomorph fishes to lower teleosts. Integration and modularity are measured using two-block partial least...

Data from: Urbanization and individual differences in exploration and plasticity

Megan Joy Thompson, Julian Claude Evans, Sheena Parsons & Julie Morand-Ferron
Urban environments impose novel challenges on animals and, as a result, the behaviors of urban wildlife are changing. In particular, high exploratory tendencies and an ability to gather more information from the environment may facilitate adoption of novel ecological opportunities. As of yet, very few studies have examined if urbanization predicts the way in which animals explore novel environments, or the extent of among-individual variation within habitats. Here, we assess exploration and it’s temporal plasticity...

Data from: The spatial structure of phylogenetic and functional diversity in the United States and Canada: an example using the sedge family (Cyperaceae)

Daniel Spalink, Jocelyn Pender, Marcial Escudero, Andrew L. Hipp, Eric H. Roalson, Julian R. Starr, Marcia J. Waterway, Lynn Bohs & Kenneth J. Sytsma
Systematically quantifying diversity across landscapes is necessary to understand how clade history and ecological heterogeneity contribute to the origin, distribution, and maintenance of biodiversity. Here, we chart the spatial structure of diversity among all species in the sedge family (Cyperaceae) throughout the USA and Canada. We first identify areas of remarkable species richness, phylogenetic diversity, and functional trait diversity, and highlight regions of conservation priority. We then test predictions about the spatial structure of this...

Data from: Elevation related difference in serial reversal learning ability in a non-scatter hoarding passerine

Ethan Hermer, Maxime Cauchoix, Alexis S. Chaine & Julie Morand-Ferron
Environments characterized by scarce and variable food supply, termed ‘harsh environments’, have been hypothesized to favor cognitive abilities that aid an animal in finding food, remembering where it is located, or predicting its availability. Most studies of the ‘harsh environment’ hypothesis have found that scatter hoarders from harsher environments have better spatial memory abilities, but few studies have looked at this hypothesis in non-scatter hoarders. Here we present the first comparison of performance on a...

Data from: The effects of male harm vary with female quality and environmental complexity in Drosophila melanogaster

Alison MacPherson, Li Yun, Tania S. Barrera, Aneil F. Agrawal & Howard D. Rundle
Mate competition provides the opportunity for sexual selection which often acts strongly on males, but also the opportunity for sexual conflict that can alter natural selection on females. Recent attention has focused on the potential of sexual conflict to weaken selection on females if male sexual attention, and hence harm, is disproportionately directed toward high over low quality females, thereby reducing the fitness difference between these females. However, sexual conflict could instead strengthen selection on...

Data from: Rapid diversification of Pseudomonas aeruginosa in cystic fibrosis lung-like conditions

Alana Schick & Rees Kassen
Chronic infection of the cystic fibrosis (CF) airway by the opportunistic pathogen Pseudomonas aeruginosa is the leading cause of morbidity and mortality for adult CF patients. Prolonged infections are accompanied by adaptation of P. aeruginosa to the unique conditions of the CF lung environment, as well as marked diversification of the pathogen into phenotypically and genetically distinct strains that can coexist for years within a patient. Little is known, however, about the causes of this...

Data from: Seed size evolution and biogeography of Plukenetia (Euphorbiaceae), a pantropical genus with traditionally cultivated oilseed species

Warren M. Cardinal-McTeague, Kenneth J. Wurdack, Erin M. Sigel & Lynn J. Gillespie
Background: Plukenetia is a small pantropical genus of lianas and vines with variably sized edible oil-rich seeds that presents an ideal system to investigate neotropical and pantropical diversification patterns and seed size evolution. We assessed the biogeography and seed evolution of Plukenetia through phylogenetic analyses of a 5,069 character molecular dataset comprising five nuclear and two plastid markers for 86 terminals in subtribe Plukenetiinae (representing 20 of ~23 Plukenetia species). Two nuclear genes, KEA1 and...

Data from: Nets versus spraying: a spatial modelling approach reveals indoor residual spraying targets Anopheles mosquito habitats better than mosquito nets in Tanzania

Emily Sohanna Acheson & Jeremy Thomas Kerr
The global implementation of malaria interventions has averted hundreds of millions of clinical malaria cases in the last decade. This study assesses predicted Anopheles mosquito distributions across the United Republic of Tanzania before large-scale insecticide-treated net (ITN) rollouts and indoor residual spraying (IRS) initiatives to determine whether mosquito net usage by children under the age of five and IRS are targeted to areas where historical evidence indicates mosquitoes thrive. Demographic and Health Surveys data from...
