Black-Tailed Prairie Dog Colony Dynamics in South Dakota Over a 10-Year Period
Between 1968 and 1978, aerial photography was used to monitor distribution of blacktailed prairie dog (Cynomys ludovicianus) colonies on a 400-square mile area in South Dakota, including parts of Buffalo Gap National Grassland, Pine Ridge Indian Reservation, and Badlands National Monument (now Badlands National Park). Aerial photographs were taken of the study area in 1968 and annually from 197...
متن کاملOptimizing habitat location for black-tailed prairie dogs in southwestern South Dakota
A spatial optimization model was formulated and used to maximize black-tailed prairie dog populations in the Badlands National Park and the Buffalo Gap National Grassland in South Dakota. The choice variables involved the strategic placement of limited additional protected habitat. Population dynamics were captured in formulations that reflected exponential population growth combined with the r...
متن کاملSpatial Optimization of Prairie Dog Colonies for Black-Footed Ferret Recovery
A discrete-time reaction-diffusion model for black-footed ferret release, population growth, and dispersal is combined with ferret carrying capacity constraints based on prairie dog population management decisions to form a spatial optimization model. Spatial arrangement of active prairie dog colonies within a ferret reintroduction area is optimized over time for maximum expected adult ferret p...
متن کاملFish assemblages, habitat conditions, and grazing effects in rolling prairie and badlands streams of the Northern Great Plains
Fish sampling was conducted over a two-year period (May to August, 2004 and 2005) in seven streams traversing the Little Missouri River National Grassland and Theodore Roosevelt National Park, western North Dakota. Fish communities of the two stream types in the region (rolling prairie and badlands) differed significantly despite their close geographic proximity, overlapping by only 18% in spec...
متن کاملArthropod Consumption by Small Mammals on Prairie Dog Colonies and Adjacent Ungrazed Mixed Grass Prairie in Western South Dakota
The percentage of arthropods and plants in the diets of seven small rodents captured on prairie dog colonies and adjacent mixed grasslands were estimated by microhistological techniques. Arthropod composition over the two year study averaged 51% and 37% on prairie dog colonies and mixed grasslands, respectively. Composition of arthropods on prairie dog colonies was greater during the summer tha...
