Different colors reveal different information: how nutritional stress affects the expression of melanin- and structurally based ornamental plumage.
Avian plumage colors have emerged recently as model systems for investigating the types of information that can be signaled by showy sexual displays in animals. In many species, the brightness ofExpand
Vertebrate pigmentation: from underlying genes to adaptive function.
Animal coloration is a powerful model for studying the genetic mechanisms that determine phenotype. Genetic crosses of laboratory mice have provided extensive information about the patterns ofExpand
Spatial heterogeneity of mesopredator release within an oceanic island system
Predator–prey communities are ubiquitous in ecology, but introduced predators can drive native species to extinction within island systems, prompting the eradication of such exotics. EcologicalExpand
Self-referent phenotype matching: theoretical considerations and empirical evidence
In most birds and mammals, young are raised in family groups. The phenotypes of nestmates and parents are thus reliable cues for recognition of conspecifics and kin. However, in some species, youngExpand
SIGNAL POLYMORPHISM IN THE WEB-DECORATING SPIDER ARGIOPE ARGENTATA IS CORRELATED WITH REDUCED SURVIVORSHIP AND THE PRESENCE OF STINGLESS BEES, ITS PRIMARY PREY
Abstract Many spiders, and in particular those in the genus Argiope, spin highly visible web decorations whose function and significance are the subject of spirited debate. In this work, we presentExpand
Song Selectivity in the Song System and in the Auditory Forebrain
Abstract: The sensorimotor neurons found in the song‐system nuclei are responsive to the sounds of the bird's own song. This selectivity emerges during vocal learning and appears to follow theExpand
Brood Parasitic Cowbird Nestlings Use Host Young to Procure Resources
Young brood parasites that tolerate the company of host offspring challenge the existing evolutionary view of family life. In theory, all parasitic nestlings should be ruthlessly self-interested andExpand
Evolutionary transitions and mechanisms of matte and iridescent plumage coloration in grackles and allies (Icteridae)
Iridescent structural colour is found in a wide variety of organisms. In birds, the mechanisms that create these colours are diverse, but all are based on ordered arrays of melanin granules within aExpand
Predictive habitat modelling for the population census of a burrowing seabird : A study of the endangered cook's petrel
Abstract Inaccurate population data remain a major problem in the conservation of burrow-nesting Procellariiform seabirds. We evaluated the potential of predictive habitat modelling, in contrast withExpand
Breeding habitat of the Cook's Petrel (Pterodroma cookii) on Little Barrier Island (Hauturu): implications for the conservation of a New Zealand endemic
Abstract Cook's Petrel (Pterodroma cookii), a trans-equatorial migrant endemic to the New Zealand archipelago, is today endangered and restricted to island habitats at the northern and southernExpand
