متن کاملQuantifying mating success of territorial males and sneakers in a bower-building cichlid fish
The strategies and traits males evolve to mate with females are incredible in their diversity. Theory on the evolution of secondary sexual characters suggests that evolving any costly trait or strategy will pay off and stabilise in the population if it is advantageous compared to the alternative less costly strategy, but quantifying the relative success of the two can be difficult. In Lake Mala...
متن کاملEvolution of bower complexity and cerebellum size in bowerbirds.
To entice females to mate, male bowerbirds build elaborate displays (bowers). Among species, bowers range in complexity from simple arenas decorated with leaves to complex twig or grass structures decorated with myriad colored objects. To investigate the neural underpinnings of bower building, we examined the contribution of variation in volume estimates of whole brain (WB), telencephalon minus...
متن کاملComparative Behavioral and Biochemical Studies of Bowerbirds, and the Evolution of Bower-Building
Unprecedented human-induced changes in the environment are causing a rapid loss of species and their habitats. Common responses to the loss of biodiversity include habitat conservation and increased efforts to understand the origin and maintenance of biodiversity. While there is no doubt that these are critical activities, it is unclear the extent to which these and related conservation approac...
