Article
According to Glen Love in Practical Ecocriticism, ecocriticism's primary challenge is the engagement of the nonhuman world in critical analysis. To engage one aspect of the nonhuman world, the animal "other" and its role in literature, ecocritics must consult scientific studies of the sensory, cognitive, and behavioral worlds of animals. Current st...

Durante la estación de cría, Callipepla californica forma grupos de dos tipos: con una sola hembra adulta asociada (grupo de familia simple) y con más de una hembra asociada (grupo de familia comunal). Aunque se asume que los grupos de familia simple son el resultado del apareamiento monógamo del macho y de la hembra asociados, a menudo se unen a e...

Proteins involved in reproduction appear to be evolving adaptively across taxa. This rapid evolution is thought to be the result of forces involved in sexual selection. One of the most often suggested of these forces is sexual conflict involving sperm competition and polyspermy avoidance. Bird species offer a unique opportunity to test this hypothe...

During the breeding season, California Quail (Callipepla californica) form two types of groups: those with a single associated adult female (single family groups), and those with more than one associated female (communal family groups). Although single family groups are assumed to be the result of a monogamous pairing of the associated male and fem...

Molecular studies of speciation in birds over the last three decades have been dominated by a focus on the geography, ecology, and timing of speciation, a tradition traceable to Mayr’s Systematics and the Origin of Species. However, in the recent years, interest in the behavioral and molecular mechanisms of speciation in birds has increased, buildi...

Callipepla californica and C. gambelii are sibling species of quail that hybridize throughout Southern California where their ranges overlap. We developed seven highly polymorphic microsatellite markers that will be used to assess introgression between these species. Numbers of alleles ranged in C. californica from seven to 24 and in C. gambelii fr...

Two processes that may be important in the evolution of multiple ornaments are (1) preference flexibility based on the distribution of local traits and (2) preferences for composite (versus partitioned) traits. To examine the occurrence of these processes we conducted three experiments measuring the mate preferences of California quail. We included...

An experiment was performed in which adult sex ratios of zebra finches, Taeniopygyia guttata castanotis, were varied to test possible effects of adult population sex ratios on sexual selection intensity and mating system dynamics in species with biparental care. The possibility that sex ratio influences the success of social mating patterns (leadin...
