Immune and oxidative stress trade-offs in four classes of Ruffs (Philomachus pugnax) with different reproductive strategies
Immunity and resistance to oxidative stress are two mechanistically related aspects of self-maintenance that are usually not studied together in connection to ecological or evolutionary relevant variables. Whereas many studies compare two sexes, here we use Ruffs (Philomachus pugnax (L., 1758)), a species in which males have three alternative reproductive morphs: independents, satellites, and f...
متن کاملThe resident's dilemma: a female choice model for the evolution of alternative mating strategies in lekking male ruffs (Philomachus pugnax)
Previous models for the evolution of alternative male mating behavior have virtually ignored the role of female choice. We present a model in which female choice favors the evolution and maintenance of alternative mating strategies in male ruffi, Philomachus pugnax. Resident male ruffe establish and defend courts on leks against other residents, while non-territorial satellite males move betwee...
متن کاملImmunocompetence and testosterone-induced condition traits in male ruffs (PHilomachus pugnax)
The immune system is costly to operate, so we expect allocation to this function to relate to other indices of overall phenotypic condition. In captive male ruffs (Philomachus pugnax), we examine covariation between three seasonal male characteristics induced by testosterone (neck ‘ruff’, facial wattles, and increases in mass/size) and cell-mediated and humoral immunity. The ruff has two geneti...
متن کاملMajor Breeding Plumage Color Differences of Male Ruffs (Philomachus pugnax) Are Not Associated With Coding Sequence Variation in the MC1R Gene
Sequence variation in the melanocortin-1 receptor (MC1R) gene explains color morph variation in several species of birds and mammals. Ruffs (Philomachus pugnax) exhibit major dark/light color differences in melanin-based male breeding plumage which is closely associated with alternative reproductive behavior. A previous study identified a microsatellite marker (Ppu020) near the MC1R locus assoc...
متن کاملGenetic variation in nuclear and mitochondrial markers supports a large sex difference in lifetime reproductive skew in a lekking species
Sex differences in skews of vertebrate lifetime reproductive success are difficult to measure directly. Evolutionary histories of differential skew should be detectable in the genome. For example, male-biased skew should reduce variation in the biparentally inherited genome relative to the maternally inherited genome. We tested this approach in lek-breeding ruff (Class Aves, Philomachus pugnax)...
