ABSTRACT Recent research has shown that landscape-level changes, namely habitat loss and fragmentation, can play an important role in determining the distribution of species across a variety of ecological systems. However, the influence of these large-scale factors in relation to small-scale factors, such as local vegetation structure or composition, is poorly understood. We used Bachman's Sparrow (Peucaea aestivalis) as a surrogate species to measure the relative importance of local vegetation… 

Predictors of Bachman's Sparrow Occupancy at its Northern Range Limit

Abstract Peucaea aestivalis (Bachman's Sparrow), a songbird endemic to the southeastern US, has experienced long-term population declines and a northern range-boundary retraction. Habitat loss and

Reproductive consequences of habitat fragmentation for a declining resident bird of the longleaf pine ecosystem

Overall, the results suggest that managers can promote breeding opportunities for Bachman's Sparrows by prioritizing resources to patches near large, preexisting longleaf pine forest to ensure ≥20% habitat within the surrounding landscape.

Nest-site selection and nest survival of Bachman's Sparrows in two longleaf pine communities

Results indicate that creating and maintaining community-specific vegetation characteristics through the application of frequent prescribed fire should increase the amount of nesting cover for Bachman's Sparrows.

Bachman's Sparrows at the northern periphery of their range: home range size and microhabitat selection

Populations of Bachman's Sparrows (Peucaea aestivalis) have declined range-wide since the late 1960s. Populations at the periphery of their range have exhibited some of the steepest declines, and

Influence of vegetation type and prescribed fire on Peromyscus abundance in a longleaf pine ecosystem

It is suggested that future research in the longleaf pine ecosystem incorporate a wider time frame to assess shortand long-term effects of fire on small mammal populations.

Area Sensitivity of Grassland Sparrows Overwintering in a South Carolina Forested Landscape

Assessment of area sensitivity of overwintering Peucaea aestivalis, Bachman's Sparrow, Ammodramus savannarum, and Henslow's Sparrow within utility rights-of-way (ROWs) at the US Department of Energy's Savannah River Site in South Carolina indicated a positive relationship with site exposure.

Management factors affecting densities of common grassland birds of high elevation grasslands of eastern South Africa: Ingula as a case study

BackgroundWorld-wide grassland birds are in decline due to habitat loss and degradation resulting from intensive agricultural practices. Understanding how key grassland habitat attributes determine



Proximate and landscape factors influence grassland bird distributions.

The influences of tree cover at both proximate and landscape scales on grassland birds, a group of birds of high conservation concern, in the Sheyenne National Grassland in North Dakota, USA, are examined to suggest that birds respond to habitat features at a variety of scales.

Effects of Hurricane Katrina and Salvage Logging on Bachman's Sparrow

Abstract. In the southeastern U. S., longleaf pine savannas, important habitat for grassland birds, are subject to hurricanes and subsequent management. The intensity of tropical storms is predicted


We examined the relationship between songbird relative abundance and local and landscape-scale habitat variables in two predominately mid- to late-successional man- aged National Forests in the

Relationships Between Landscape Structure and Breeding Birds in the Oregon Coast Range

This work investigated the relationship between landscape structure and breeding bird abundance in the central Oregon Coast Range and found that species' abundances were generally greater in the more heterogenous landscapes; that is, they were associated with the more fragmented distribution of habitat.


--The vegetation structure of Bachman's Sparrow (Aimophila aestivalis) breeding habitat and its relationship to home range size was studied on pine plantations in central Arkansas. Univariate and

Seeking Parsimony in Landscape Metrics

ABSTRACT Numerous metrics describing landscape patterns have been used to explain landscape-scale habitat selection by birds. The myriad metrics, their complexity, and inconsistent responses to

Nest-Site Characteristics of Bachman's Sparrows and Their Relationship To Plant Succession Following Prescribed Burns

Abstract Prescribed fire is a frequently applied land-management tool for the preservation and maintenance of southern pine woodlands. Many avian species benefit from the use of prescribed fire in
