Complex relationship between multiple measures of cognitive ability and male mating success in satin bowerbirds, Ptilonorhynchus violaceus
Many animal species have complex cognitive abilities previously assumed to be limited to humans. Explanations for how these abilities evolved have focused on ways in which cognitive performance mayExpand

Male satin bowerbird problem-solving ability predicts mating success
Mate choice and mate attraction are important behaviours influencing the evolution of elaborate traits. It is possible that male general cognitive performance plays an important role in sexualExpand

Cognitive ability and the evolution of multiple behavioral display traits
Males of many species have multiple behavioral display traits. Females may be able to use these multiple behavioral display traits together to evaluate a male's overall cognitive ability, which mayExpand

Aerobic capacity in wild satin bowerbirds: repeatability and effects of age, sex and condition
SUMMARY Individual variation in aerobic capacity has been extensively studied, especially with respect to condition, maturity or pathogen infection, and to gain insights into mechanistic foundationsExpand

On the role of male competition in speciation: a review and research agenda
Little attention has been given to how males competing for mates can facilitate the evolution and persistence of new species. We expand the current framework for how new species evolve (speciation)Expand

Created versus natural wetlands: Avian communities in Virginia salt marshes
Abstract Permits to destroy wetlands often require the creation of the same type of wetland elsewhere. An assumption underlying this practice is that such created wetlands will replace the ecologicalExpand

Why does the magnitude of genotype‐by‐environment interaction vary?
Abstract Genotype‐by‐environment interaction (G × E), that is, genetic variation in phenotypic plasticity, is a central concept in ecology and evolutionary biology. G×E has wide‐ranging implicationsExpand

An inverse relationship between decoration and food colour preferences in satin bowerbirds does not support the sensory drive hypothesis
Male bowerbirds collect and decorate their bowers with coloured objects that influence female choice. A recent version of the sensory drive hypothesis claims that female food colour preferences haveExpand

Male competition fitness landscapes predict both forward and reverse speciation.
Speciation is facilitated when selection generates a rugged fitness landscape such that populations occupy different peaks separated by valleys. Competition for food resources is a strong ecologicalExpand

Replacing Sources with Sinks: When Do Populations Go Down the Drain?
We investigate the scenario in which some amount of higher quality habitat is destroyed and is then replaced by some undetermined amount of lower quality habitat. We examined how much low-qualityExpand
