State-space modeling to support management of brucellosis in the Yellowstone bison population
The bison (Bison bison) of the Yellowstone ecosystem, USA, exemplify the difficulty of conserving large mammals that migrate across the boundaries of conservation areas. Bison are infected with brucellosis (Brucella abortus) and their seasonal movements can expose livestock to infection. Yellowstone National Park has embarked on a program of adaptive management of bison, which requires a model ...
متن کاملBateman’s Principle in Cooperatively Breeding Vertebrates: The Effects of Non-breeding Alloparents on Variability in Female and Male Reproductive Success1
SYNOPSIS. The sex-specific slopes of Bateman’s gradients have important implications for understanding animal mating systems, including patterns of sexual selection and reproductive competition. Intersexual differences in the fitness benefits derived from mating with multiple partners are expected to yield distinct patterns of reproductive success for males and females, with variance in direct ...

متن کاملEvaluation of Genetic Variability in a Breeder Flock of Native Chicken Based on Randomly Amplified Polymorphic DNA Markers
A study was undertaken to evaluate the genetic variation in the 10th generation of a breeder flock of native breed selected for high egg and meat production in native fowls breeding station, Mazandaran, Iran. Venous blood samples were collected from 100 birds of both sexes. The RAPD-PCR technique was applied to generate a DNA fingerprint of individuals. Initially, a total of 20 ten-nucleotide a...
