| at-sea behavior varies with lunar phase in a nocturnal pelagic seabird, the swallow-tailed gull. | strong and predictable environmental variability can reward flexible behaviors among animals. we used long-term records of activity data that cover several lunar cycles to investigate whether behavior at-sea of swallow-tailed gulls creagrus furcatus, a nocturnal pelagic seabird, varied with lunar phase in the galápagos islands. a bayesian hierarchical model showed that nighttime at-sea activity of 37 breeding swallow-tailed gulls was clearly associated with changes in moon phase. proportion of n ... | 2013 | 23468889 |
| novel haemoproteus species (haemosporida: haemoproteidae) from the swallow-tailed gull (lariidae), with remarks on the host range of hippoboscid-transmitted avian hemoproteids. | haemoproteus (haemoproteus) jenniae n. sp. (haemosporida: haemoproteidae) is described from a galapagos bird, the swallow-tailed gull creagrus furcatus (charadriiformes, laridae), based on the morphology of its blood stages and segments of the mitochondrial cytochrome b (cyt b) gene. the most distinctive features of h. jenniae development are the circumnuclear gametocytes occupying all cytoplasmic space in infected erythrocytes and the presence of advanced, growing gametocytes in which the pelli ... | 2012 | 22324933 |
