Furthermore, the frequency of turn angles was highly variable in cropland. In contrast, skunk pathways did not differ between LGC and HGC landscapes. They were more influenced by wetlands than by the landscape composition of grassland. Skunks spent more time in back and forth movement in all habitats. The rate of movement was faster in cropland than in planted cover in LGC but not in HGC landscapes. When I simulated random combinations of predator movement and waterfowl nests there was essentially no relationship between planted cover patch size and the predicted proportion of nests that would be encountered by predators. However, the observed proportion of nests encountered by predators in intermediate sized patches (50- 120 ha) was frequently greater than the proportion predicted by random activity. This study has led to a refined understanding of how predators perceive the landscape and is an important contribution to both predator landscape ecology and waterfowl management.

In the prairie pothole region, high predation rates often reduce duck nest success below the 15-20% thought necessary for population stability. Lethal removal of mammalian predators of duck nests is one potential management option, but there is little reliable information about effects on nest success of removing mammalian predators without using poisons. On 16 4,150-ha blocks half of them trapped during spring and summer, I found higher (P0.001) nest success on trapped sites (45%) than on untrapped sites (17%). There were no year (P=0.296)year-treatment (P=0.423), or species-treatment (P0.895) effects. Nest success of blue-winged teal (Anas discors) and gadwalls (A. strepera)was higher than that of mallards (A. platyrhynchos) and pintails (A.acuta, P=0.028) on trapped and untrapped sites. Nest success was positively related to numbers of predators removed (P

Although Bissonette (Utah Cooperative Fish and Wildlife Research Unit, Utah State U., U.S.) and Storch (Weihenstephan Center of Life Sciences, Technische U. Munchen, Germany) state that a cohesive theory of landscape ecology is not yet possible, they present 17 papers they see as providing elements of theoretical framework, specifically as related to problems of resource management practice. Separate sections address linkages between conceptual and quantitative issues, between people and the landscape, and between theory and management in the field.

Results of habitat fragmentation studies on grassland and wetland birds are not consistent. Some studies have found positive relationships among abundance, nest success, field size, and distance to edges, whereas others have found no relationship. One reason for differing results may be the landscape composition in which the study took place. I examined how landscape composition influenced relations among: 1) occurrence and abundance of grassland songbirds and field size and 2) nest success of ducks, field size, and edges. I also investigated the effects of mowing on grassland songbirds, and how landscape features, such as amount of perennial grassland, and predator community composition influenced the nest success of ducks in fields. The study took place in the Prairie Pothole Region of central North Dakota during the 1996-1997 breeding seasons. Two types of 6.4 x 6.4 km study areas were selected based on the amount of perennial grassland they contained: 15-20% and 51-55%. The remaining portion of the study areas was primarily cropland and wetland.
