Individual and temporal variability in the courtship behavior of White- ruffed Manakins (Corapipo altera), a species with facultative cooperative displays
Investigation of the ecological and evolutionary basis for the often-intriguing courtship behavior of animals requires that we understand the patterns of variation inherent in such behaviors. The courtship displays of the White-ruffed Manakin (Corapipo altera) are not well-known, and previously published descriptions and interpretations of displays conflict with one another. We studied the repr...
متن کاملLekking birds in a tropical forest forego sex for migration.
Facultative, partially migratory animals provide a contemporary window into the evolution of migration, offering rare opportunities to examine the life-history trade-offs associated with migration. For the first time, to our knowledge, we describe the nature of these trade-offs, using a lek-breeding tropical bird, the white-ruffed manakin (Corapipo altera). Previous evidence indicated that weat...
متن کاملStorms drive altitudinal migration in a tropical bird.
Although migration is a widespread and taxonomically diverse behaviour, the ecological factors shaping migratory behaviour are poorly understood. Like other montane taxa, many birds migrate along elevational gradients in the tropics. Forty years ago, Alexander Skutch postulated that severe storms could drive birds to migrate downhill. Here, we articulate a novel mechanism that could link storms...
متن کاملA molecular phylogenetic hypothesis for the manakins (Aves: Pipridae).
Phylogenetic relationships among the 14 manakin genera were inferred from DNA sequence data obtained from both mitochondrial and nuclear DNA loci. Phylogenetic analysis resulted in a well-supported hypothesis that corroborates a sister relationship between tyrant-manakins and the "core" manakins (Antilophia, Chiroxiphia, Corapipo, Dixiphia, Heterocercus, Ilicura, Lepidothrix, Manacus, Masius, M...
متن کاملTwo new species of Leptobatopsis Ashmead (Hymenoptera: Ichneumonidae: Banchinae) from South Korea and gynandromorphy in L. nigricapitis.
Four species of Leptobatopsis Ashmead are recorded for the first time from South Korea. Among them, L. koreana sp. nov. and L. daedeokensis sp. nov. are newly described. We also report two newly recorded species, L. nigricapitis Chandra & Gupta and L. appendiculata Momoi, from South Korea. In addition, we describe a case of gynandromorphy of L. nigricapitis in a single specimen from South Korea...
