Abstract: Modern farm practices can vary in their emphasis on tillage versus chemicals to control weeds, and researchers know little about which emphasis has greater ecological benefits. We compared avifaunas of uplands and wetlands in four treatments: conventional farms, conservation farms (contrasting those that minimized frequency of tillage [minimum tillage] with those that eliminated chemical inputs [organic]), and restored or natural (wild) sites in Saskatchewan, Canada. Of 37 different… 
Tillage and herbicide reduction mitigate the gap between conventional and organic farming effects on foraging activity of insectivorous bats
It is shown that bat activity was always higher in OT than in T systems for two of three species and for one of two genera, as well as greater species richness, which highlights an important benefit of organic farming and contrasted effects in conventional farming.
Effects of in ovo herbicide exposure in newly hatched domestic chickens (Gallus gallus) and ducks (Anas platyrhynchos)
Assessment of whether in ovo exposure to the herbicides 2,4-D and Buctril-M adversely affects genetic material and/or immune system function in newly hatched domestic chickens and ducks, as surrogates for wild bird species.
Comparison of restored and natural wetlands as habitat for birds in the prairie pothole region of Saskatchewan, Canada.
— To enhance upland and wetland habitat for waterfowl under the North American Waterfowl Management Plan, Ducks Unlimited Canada restored hundreds of wetlands throughout the Prairie Pothole Region in
From Relict Saline Wetlands to New Ecosystems: Changes in Bird Assemblages
Summary. In the Pampa ecoregion of South America, the replacement of semi-natural ecosystems by agroecosystems is a major cause of biodiversity decline. Agricultural intensification has led to the
Bush, bugs, and birds; interdependency in a farming landscape
Ecotone width is the best predictor of avian densities and arthropod richness while percent gap is the most important factor if a manager wishes to increase avian diversity (H’) in hedgerow habitats.
Assessing the impact of local habitat variables and landscape context on riparian birds in agricultural, urbanized, and native landscapes
Large tracts of natural habitat are being replaced by agriculture and urban sprawl in Mediterranean regions worldwide. We have limited knowledge about the effects of human activities on native
Influence of Local and Landscape Characteristics on Avian Richness and Density in Wet Playas of the Southern Great Plains, USA
Playa wetlands (shallow, circular, depressional wetlands) in the Southern Great Plains are essential to the maintenance of regional biodiversity. However, the relative importance of habitat

Novel information is provided to help farmers and others understand the cover crop preferences of sparrows, and ways that farmers might use mustard cover crops as trap crops to reduce White-crowned Sparrow feeding damage on winter and spring vegetable crops are provided.
Analysis of trends and agricultural drivers of farmland bird declines in North America : A review
Globally, agriculture has intensified during the past 50 years due to increased mechanization, changes in the timing of farming operations, grassland conversion to cropland, and increased


Soil Organic Matter Recovery in Semiarid Grasslands: Implications for the Conservation Reserve Program
It is suggested that 50 yr is an adequate time for recovery of active soil organic matter and nutrient availability, but recovery of total soilorganic matter pools is a much slower process.
Foraging Patterns of Vesper Sparrows (Pooecetes gramineus) Breeding in Cropland
It is suggested that vesper sparrows can be protected, in part, from the harmful effects of pesticides by limiting pesticide use in areas where foraging is concentrated, and that foraging opportunities for this species may be enhanced by reduced tillage farming methods.
If insect levels are influenced by the amount of crop residue in fields, then increased use of conservation tillage could influence food availability to pheasant broods in row crops.
A Review and Synthesis of Habitat Use by Breeding Birds in Agricultural Landscapes of Iowa
Existing information on bird species composition, abundance and nesting sta- tus during the breeding season (May through July) was compiled for habitats characteristic of the agricultural landscapes

The Conservation Reserve Program: habitat for grassland birds
The Conservation Reserve Program (CRP) has effected major changes to the landscape, especially in the northern Great Plains. Breeding birds have responded dramatically to habitat changes by
Bird use and nesting in conventional, minimum-tillage, and organic cropland
Seasonal bird use and nesting activity in fallow, sunflower, and wheat fields among conventional farms, minimum-tillage farms, and organic farms in southeast North Dakota showed low hatching success for waterfowl and shorebirds and passerines and nest success was low for passerines.
