Abstract Understanding the influences of habitat fragmentation on vertebrate populations is essential for the protection and ecological restoration of strategic sites for native species. We examined the effects of prairie fragmentation on avian reproductive success using artificial and natural nests on 26 randomly selected, privately owned patches of shortgrass prairie ranging in size from 7 to 454 ha within a cropland matrix in Washington County, Colorado, summer 2000. Survival trends of… Expand

Land Use and Small Mammal Predation Effects on Shortgrass Prairie Birds
Abstract Grassland birds endemic to the central shortgrass prairie ecoregion of the United States have experienced steep and widespread declines over the last 3 decades, and factors influencing… Expand
Effects of fire and grazing on grasshopper sparrow nest survival
TLDR
The effects of the patch-burn grazing and a more traditional treatment on the nesting ecology of grasshopper sparrows in small grasslands located in southern Iowa are assessed and further investigation of heterogeneity management in fragmented landscapes is recommended to better understand how it affects biodiversity in relatively small management units that typify grassland habitats in the Midwest.

Management and Conservation Effects of Prescribed Burning on Avian Nest Survival in the Southern Great Plains
Shrubs, such as mesquite (Prosopis spp.) and cholla (Opuntia spp.), now dominate firesuppressed grasslands in southwestern North America. Responses of birds to prescribed burning of the shortgrass… Expand
Effects of Fire and Grazing on Grasshopper
TLDR
Although survival rates were highest in patch-burn grazed pastures, multiple factors influenced grasshopper sparrow survival, and further investigation of heterogeneity management in fragmented landscapes is recommended to better understand how it affects biodiversity in relatively small management units that typify grassland habitats in the Midwest.

FRAGMENTION BY AGRICULTURE INFLUENCES REPRODUCTIVE SUCCESS OF BIRDS IN A SHRUBSTEPPE LANDSCAPE
TLDR
Simple models of population growth using landscape-specific fecundity and estimates of adult survival derived from return rates of banded male Sage Sparrows and Brewer's Sparrows suggest that fragmented shrubsteppe in Washington may be acting as a population sink for some species. Expand
Effects of prescribed burning on avian nest survival in the southern Great Plains
TLDR
In semiarid grasslands heavily inundated with shrubs, prescribed burning may positively influence the nest success of some bird species, including mourning dove and lark sparrow. Expand
Bird Productivity and Nest Predation in Agricultural Grasslands
Effective conservation strategies for grassland birds in agricultural landscapes require understanding how nesting success varies among different grassland habitats. A key component to this is… Expand
Maximizing the effectiveness of grassland management for a grasshopper sparrow (Ammodramus savannarum) metapopulation
TLDR
Examination of the effect of increasing levels of hayfield enrollment on grasshopper sparrow population viability in an urbanizing region of New Jersey demonstrates that extinction risk can be reduced without having to protect or manage all remaining grassland habitat in the landscape. Expand
Extremes of heat, drought and precipitation depress reproductive performance in shortgrass prairie passerines
Climate change elevates conservation concerns worldwide because it is likely to exacerbate many identified threats to animal populations. In recent decades, grassland birds have declined faster than… Expand

DOES HABITAT FRAGMENTATION INFLUENCE NEST PREDATION IN THE SHORTGRASS PRAIRIE?
Abstract We examined the effects of habitat fragmentation and vegetation structure of shortgrass prairie and Conservation Reserve Program (CRP) lands on predation rates of artificial and natural… Expand
Duck nesting success in a fragmented prairie landscape: is edge effect important?
Habitat fragmentation and the creation of extensive edges have been postulated as causes of higher nest predation in many species of birds. In this study we tested the hypothesis that predation on… Expand
EVIDENCE FOR EDGE EFFECTS ON MULTIPLE LEVELS IN TALLGRASS PRAIRIE
TLDR
It is argued that, based on edge avoidance behavior, “grassland-interior” species such as the Henslow's Sparrow respond to edge effects mainly by a decrease in density, whereas habitat generalists such asThe Dickcissel are affected mainly byA decrease in nesting success. Expand
PREDATION ON REAL AND ARTIFICIAL NESTS IN SHRUBSTEPPE LANDSCAPES FRAGMENTED BY AGRICULTURE
TLDR
Increased predation by corvids and lower nest success in fragmented landscapes may have played a part in recent declines of some shrubsteppe birds, and future research should measure annual reproductive success of individual females and survival rates of juveniles and adults. Expand
Patterns of Area Sensitivity in Grassland-Nesting Birds

Effects of prairie fragmentation on predation on artificial nests
TLDR
Proximity to woody cover had more influence on artificial-nest success than did tract size when both variates were incorporated in multiple logistic regression and log-linear models. Expand

Effects of prairie fragmentation on the nest success of breeding birds in the midcontinental United States
TLDR
Differences in nest-predation rates between large fragments and small fragments suggest that fragmentation of prairie habitats may be contributing to regional declines of grass- land birds and may require protection and restoration of large prairie areas. Expand

Variation in top‐down control of avian reproductive success across a fragmentation gradient
TLDR
These findings suggest that another process -- perhaps differential survivorship or dispersal - yields reduced abundance of ground-nesting species in habitat fragments, which would reflect that the strength of top-down forces across a landscape varies with characteristics of predator and prey and their autecological responses to ecological gradients.
