Sage-grouse Nesting and Brood Habitat Use in Southern Canada
Greater sage-grouse (Centrocercus urophasianus) populations have declined from 66 to 92% during the last 30 years in Canada, where they are listed as endangered. We used radiotelemetry to examine greater sage-grouse nest and brood habitat use in Alberta and assess the relationship between habitat and the population decline. We also identified the patch size at which sage-grouse were selecting n...
متن کاملSage-Grouse Habitat Selection During Winter in Alberta
Greater sage-grouse (Centrocercus urophasianus) are dependent on sagebrush (Artemisia spp.) for food and shelter during winter, yet few studies have assessed winter habitat selection, particularly at scales applicable to conservation planning. Small changes to availability of winter habitats have caused drastic reductions in some sage-grouse populations. We modeled winter habitat selection by s...
متن کاملPoint Intercept and Line Intercept Methods for Aquatic Plant Management
The use of quantitative methods for aquatic plants has not become as standardized as other components in the aquatic ecosystem, such as biotic (e.g., fish) or physical components (e.g., water chemistry) (APHA 1995, Lind 1979, Wetzel and Likens 1991). Even when considering aquatic biomass sampling, which is a widely accepted means of quantifying aquatic plant communities, there is considerable d...

متن کاملSage-Grouse and Indirect Interactions: Potential Implications of Coyote Control on Sage-Grouse Populations
Coyotes (Canis latrans) are lethally controlled throughout the range of Greater Sage-Grouse (Centrocercus urophasianus) and it has been suggested that such control may benefit sage-grouse. However, the perceived benefits of control are based on the direct effects of coyotes on sage-grouse and largely ignore potential indirect interactions. Here, we summarize some of the evidence for direct effe...
