Download or read book Optimum Timeframes for Detecting Songbird Vocalizations in the Black Hills written by Todd R. Mills and published by . This book was released on 2000 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Birds are indicators of vegetation structure and ecological conditions. The singing activity of birds declines during late-morning periods, which can affect estimates of abundance and conclusions regarding vegetative conditions indexed by birds. Therefore, it is important to quantify periods of bird activity so biologists can plan studies. We determined hourly detections from singing males of 22 nongame bird species in ponderosa pine, quaking aspen, and grassland vegetation types in the Black Hills of South Dakota. Detections of 12 of 22 species differed among 1-hr intervals after sunrise. Detections of yellowrumped warblers, Townsend's solitaires, red-breasted nuthatches, western tanagers, and American robins decreased on count-episodes more than 4 hrs after sunrise. Detections of dusky flycatchers declined on count-episodes more than 3 hrs after sunrise and detections of black-capped chickadees were greatest during the first hour after sunrise and declined afterward. Detections of many other species from songs or calls decreased on count-episodes more than 5 hrs after sunrise. We recommend that bird counts in the Black Hills be completed within 4 hrs after sunrise so estimates of bird abundance are not affected by reduced singing among males.

This book was released on 2001 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prairie woodlands comprise about 1 percent of the landscape in the northern Great Plains. However, prairie woodlands provide habitat for far more than 1 percent of the wildlife species that occur in the prairie region. With increasing pressures on natural resources, managers need methods for managing wildlife habitat and biodiversity that are based on ecological processes. We studied the small mammals and vegetation in seral stages of four woodland types in central South Dakota. None of the species was restricted to a single seral stage, but abundance of some small mammals varied depending on seral stages of woodland types. To ensure the biodiversity of the prairie, managers should retain all seral stages of all prairie woodlands.

Download or read book Spring Fires in a Semimature Trembling Aspen Stand in Central Alberta written by Martin E. Alexander and published by . This book was released on 1991 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a May 1972 study in central Alberta, 13 0.5 ha plots of semimature trembling aspen were burned experimentally under various conditions to provide new information on fire behaviour and impact, with particular regard to aspen ecosystems. Fire data were documented for all plots, particularly head fire rates of spread and frontal fire intensities. The following August an assessment was made of the impact of burning on aspen overstory mortality and understory vegetation response. In May 1978 two of the plots were jointly reburned. The August survey that followed assessed the effects of the reburning.
