Historic Distribution And Ecology Of Tall-Grass Prairie In Western Canada, Darcy C. Henderson, Nicola Koper
Historic Distribution And Ecology Of Tall-Grass Prairie In Western Canada, Darcy C. Henderson, Nicola Koper
The Prairie Naturalist
Rapid settlement and agricultural development of western Canada in the late 1800s and early 1900s nearly eliminated the tall-grass prairie, and pre-empted a detailed description by ecologists. A combination of literature review and historical ecological analysis of soils, climate, and composition data are applied to estimate the historic distribution, and area occupied by tall-grass prairie in southern Manitoba and southeastern Saskatchewan, Canada. The resulting area estimate of 20,830 km2 is more than three times any previously reported value. Some confusion of terms from the first half of the 1900s, and the impact of invasive species on vegetation patterns observed …

Monteverde: Ecology And Conservation Of A Tropical Cloud Forest - 2014 Updated Chapters, Nalini M. Nadkarni, Nathaniel T. Wheelwright
Bowdoin Scholars' Bookshelf
The Monteverde Cloud Forest Reserve has captured the worldwide attention of biologists, conservationists, and ecologists and has been the setting for extensive investigation over the past 40 years. Roughly 40,000 ecotourists visit the Cloud Forest each year, and it is often considered the archetypal high-altitude rain forest. “Monteverde: Ecology and Conservation of a Tropical Cloud Forest”, edited by Nalini Nadkarni and Nathaniel T. Wheelwright (Oxford University Press, 2000 and Bowdoin’s Scholar’s Bookshelf. Book 1 ), features synthetic chapters and specific accounts written by more than 100 biologist and local residents, presenting in a single volume everything known in 2000 about …
Burrowing Owl Associations With Black-Tailed Prairie Dog Colonies In Southwestern Kansas And Southeastern Colorado, Stephen L. Winter, Jack F. Cully Jr.
Burrowing Owl Associations With Black-Tailed Prairie Dog Colonies In Southwestern Kansas And Southeastern Colorado, Stephen L. Winter, Jack F. Cully Jr.
The Prairie Naturalist
We quantified the use of black-tailed prairie dog (Cynomys ludovicianus) colonies as habitat for the burrowing owl (Athene cunicularia) in southwestern Kansas and southeastern Colorado. We used incidental sightings and breeding season avifauna surveys to document the presence of the burrowing owl on black-tailed prairie dog colonies, non-colonized rangeland, and cropland during the spring and early summer. Burrowing owl rarely was observed on noncolonized rangeland and cropland sites, and black-tailed prairie dog colonies appear to be used substantially as a habitat type for the burrowing owl in the region encompassing Cimarron and Commanche National Grasslands in …
