This book was released on 1972 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The taxonomic treatments for Intermountain Flora were published between 1972 and 2012 in eight parts, volumes 1, 2A, 2B, 3A, 3B, 4, 5, and 6. Included in this, the ninth part of the series, are miscellany that did not fit conveniently in the volumes with taxonomic treatments. For the past three years, we have informally referred to this volume as the 'Supplement, ' but because of the mixed nature of the contents, we have decided to call it volume 7, 'the potpourri volume.' It contains acknowledgments of individuals and institutions; keys to all families; an alphabetical list of families with volume numbers and authors; a history of the project; biographies of Bobbi Angell, Rupert C. Barneby, Arthur Cronquist, Arthur H. Holmgren, Noel H. Holmgren, Patricia K. Holmgren, Jeanne R. Janish, Bassett Maguire, James L. Reveal, and Arnold (Jerry) Tiehm; photographs of authors, artists, and plant collectors of the Intermountain West; an update to the 1984 treatment of Intermountain Penstemon published in volume 4; a list of general references and online resources; an expanded glossary; a list of nomenclatural innovations, typifications, and chromosome data; an index to people whose photographs appear in Intermountain Flora; and a cumulative index for all seven volumes. The eight earlier volumes include descriptions of 146 vascular plant families (plus three cultivated families [Aquifoliaceae, Thymelaeaceae, and Tropaeolaceae] incidentally mentioned), 898 genera, 3847 species, and 1571 varieties. An additional 426 cultivated species and 551 extralimital taxa are treated in keys and/or discussions. The five largest families are Asteraceae (volume 5), Poaceae (volume 6), Fabaceae (volume 3B), Brassicaceae (volume 2B), and Scrophulariaceae (volume 4). The five largest genera are Astragalus (volume 3B), Eriogonom (volume 2A), Penstemon (volume 4), Carex (volume 6), and Erigeron (volume 5). The four authors (Barneby, Cronquist, Noel and Patricia Holmgren) based at the New York Botanical Garden prepared manuscript for 82% of the 3867 pages in the volumes with taxonomic treatments. In addition, Noel did the page composition and layout of illustrations, and Pat edited the manuscripts and compiled the index. In this volume, Noel designed the photo albums and prepared the keys to families, the history, the biographies of authors, artists, and Maguire, the Penstemon update, and the glossary, and Pat compiled the list of families and the indices, gathered photographs of the artists, authors, and collectors, and prepared the biography of Tiehm."--Introduction to volume 7.

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.

Download or read book Bird Habitat Relationships Along a Great Basin Elevational Gradient written by Dean E. Medin and published by . This book was released on 2000 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bird censuses were taken on 11 study plots along an elevational gradient ranging from 5,250 to 11,400 feet. Each plot represented a different vegetative type or zone: shadscale, shadscale-Wyoming big sagebrush, Wyoming big sagebrush, Wyoming big sagebrush-pinyon/juniper, pinyon/juniper, pinyon/juniper-mountain big sagebrush, mountain big sagebrush, mountain big sagebrush-mixed conifer, mixed conifer, mixed conifer-alpine, and alpine. Eighty-nine bird species were observed. The total number of birds and bird species followed a skewed bell-shaped distribution. Some birds were quite narrow in their choice of vegetative zones while others showed very little selectivity. Both total number of individual birds and bird species appeared to reach highest values in study plots with a substantial component of mountain big sagebrush.
