Population Demography of the Yellowstone National Park Bison Herds: Author: Fuller, Julie Ann; Date: 2006-05-15; Program: Fish and Wildlife Management; Abstract: The bison population of Yellowstone National Park (YNP) represents an outstanding conservation success story, as their numbers have increased from just 46 in 1902 to >4,000 today. Bison are keystone herbivores in YNP, and are central to several management controversies due to their infection with brucellosis. I integrated 100 years of historical count data with 7 years of recent vital rate data, and parameterized a matrix model using these vital rates to validate population growth estimates and to project future management scenarios involving disease control through vaccination and/or culli...; Download File | View full details

Spatio-Temporal Dynamics of the Central Bison Herd in Yellowstone National Park: Author: Bruggeman, Jason Edward; Date: 2006-08-15; Program: Fish and Wildlife Biology; Abstract: The spatio-temporal dynamics of Yellowstone National Park bison (Bison bison) are complex and affected by multiple abiotic and biotic mechanisms. In the Madison- Firehole area, which provides winter range for the migratory central herd, this suite of effects is particularly intricate owing to geothermally influenced habitats, severe winter climate, and variability in resource distribution. Understanding factors influencing bison spatio-temporal dynamics is of importance to Yellowstone, which is faced with managing a growing bison population that is expanding its range. I gathered data from 199...; Download File | View full details
