Avian Ecology and Conservation in an Urbanizing World
Author: John M. Marzluff
Publisher: Springer Science & Business Media
ISBN: 1461515319
Category : Science
Languages : en
Pages : 581
Book Description
One of the most striking and persistent ways humans dominate Earth is by changing land-cover as we settle a region. Much of our ecological understanding about this process comes from studies of birds, yet the existing literature is scattered, mostly decades old, and rarely synthesized or standardized. The twenty-seven contributions authored by leaders in the fields of avian and urban ecology present a unique summary of current research on birds in settled environments ranging from wildlands to exurban, rural to urban. Ecologists, land managers, wildlife managers, evolutionary ecologists, urban planners, landscape architects, and conservation biologists will find our information useful because we address the conservation and evolutionary implications of urban life from an ecological and planning perspective. Graduate students in these fields also will find the volume to be a useful summary and synthesis of current research, extant literature, and prescriptions for future work. All interested in human-driven land-cover changes will benefit from a perusal of this book because we present high altitude photographs of each study area.

The Effects of Forest Management Practices on Nongame Birds
Author: Marie Theresa Nietfeld
Publisher:
ISBN:
Category : Bird populations
Languages : en
Pages : 322
Book Description
"This annotated bibliography contains over 700 references which deal with: (1) effects, direct and indirect, of forest management practices on nongame forest birds, covering such topics as logging, cut types, rotation periods, thinning, site preparation, plantations, pesticides, herbicides, burning and regeneration: (2) forest bird-habitat relationships in both natural and sites disturbed by forestry operations or other practices which would produce similar situations; (3) factors affecting species diversity and biogeography distributions; (4) the role of birds in the forest ecosystem; and (5) management and conservation considerations for nongame forest birds, and sorne related techniques. The emphasis was placed on migratory songbirds in the boreal forest area. However, since few studies have investigated the effects of forestry practices on this category of birds in the boreal region, information was included for a variety of habitat types from aIl over North America, and a few from other regions. It was hoped that the findings and management considerations in these papers would provide usefuI information, and that some of the trends observed could be applied to the boreal region"--Abstract, p. iii.

Wildlife Habitats in Managed Rangelands
Author: Jack Ward Thomas
Publisher:
ISBN:
Category : Forests and forestry
Languages : en
Pages : 24
Book Description
Riparian zones can be identified by the presence of vegetation that requires free or unbound water or conditions that are more moist than normal (fig. 1) (Franklin and Dyrness 1973, Minore and Smith 1971). Riparian zones can vary considerably in size and vegetative complex because of the many combinations that can be created between water sources (fig. 2) and physical characteristics of a site. Such characteristics include gradient, aspect, topography, soil, type of stream bottom, water quality, elevation, and plant community (Odum 1971). All riparian zones within managed rangelands of the western United States, however, have the following in common: (1) they create well-defined habitat zones within the much drier surrounding areas; (2) they make up a minor proportion of the overall area; (3) they are generally more productive in terms of biomass-plant and animal-than the remainder of the area; and (4) they are a critical source of diversity within rangelands (fig. 3). Carothers (1977), Carothers and Johnson (19751, and Curtis and Ripley (1975) have prepared summary papers on the subject of riparian habitats as associated with both range and forest areas.
