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

Effects of Habitat Management for Ducks on Target and Nontarget Species

It is suggested that in dry mixed-grass prairie, deferring cattle grazing is likely to increase densities of only lesser scaup but that grazing, in general, can be used by managers to create a heterogeneous habitat that supports many species.

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

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.

Duck nesting in intensively farmed areas of North Dakota

Poor quality nesting cover, the result of intensive land use practices, and nesting failures caused by machinery and predators, mainly mammals, were the principal factors limiting duck nesting and production on intensively farmed areas in eastern North Dakota.

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.
