Lek ecology of male greater sage-grouse in Carbon County, Wyoming
… should be able to accurately relate sage-grouse lek count data to population sizes. Behavior during the breeding season, such as how frequently males visit their leks or move among leks, could relate to a male sage-grouse�s ability to establish dominance at his lek and mate, so it is important to …

Operans dubbla tidsförlopp : Musikdramaturgin i bilradiooperan Själens rening genom lek och skoj
Title: The Twofold Rhythm of Duration in Opera. The Musical Dramaturgy of the Car Radio Opera "Cleansing of the Soul through Fun and Games". This thesis focuses on musical dramaturgy in operas with a story. I believe my own music is better when I write operas than instrumental music. The question …

Bridging the divide : incorporating local ecological knowledge into U.S. natural resource management
… the value of local ecological knowledge (LEK), a system of knowledge developed over time through observation and interaction with the natural environment. Although advocates have expounded the benefits of using LEK, in practice, LEK is rarely integrated into the scientific assessments that …

Sharp-Tailed Grouse (Tympanuchus phasianellus) Habitat Selection and Population Trends in Saskatchewan
… of the sharp-tailed grouse in Saskatchewan. Leks, communal dancing grounds, form the basis for much of the life history knowledge of sharp-tailed grouse and are often used in the management of the species. Correspondingly, the probability of lek occurrence is an excellent indicator of habitat …

Influence of the Conservation Reserve Program and Landscape Composition on the Spatial Demographics of Prairie Grouse in Northeastern South Dakota
… U.S.A., during 2007 and 2008. I searched for leks in three, 10000-ha study areas with dissimilar landscape compositions including varying influence of the CRP grasslands and agriculture intensity. I defined and digitized the entire landscape in the study areas into nine general land use …

Analyses of Greater Sage-Grouse (Centrocercus urophasianus) Translocation Release Methods and Chick Survival in Strawberry Valley, Utah
… were released within 250 m of the only active lek in Strawberry Valley while males were actively strutting. A prolonged winter in 2006 delayed normal lekking activity in Strawberry Valley. As a result 61 (59%) of the 103 sage-grouse translocated in 2006 were not released near an active lek. We …

Mapping elk distribution on the Canadian prairies: Applying local knowledge to support conservation
… by using both local ecological knowledge (LEK) and biological research techniques in tandem. Integrating LEK with more conventional biological research can provide complementary data at contrasting time and spatial scales and facilitates comparison of multiple independent datasets. …

Distribution and Landscape Attributes of Greater Prairie Chickens and Sharp-Tailed Grouse Outside of Their Traditional Range in South Dakota
… landscape attributes within 3,000 m of leks, and analyzes landscape characteristics using GIS modeling to develop a predictive model. Survey routes were developed in areas of potential suitable habitat and were sampled beginning ½ hour before sunrise and ending 2 to 2½ hours after …

Greater Sage-Grouse Response to Coal-Bed Natural Gas Development and West Nile Virus in the Powder River Basin, Montana and Wyoming, USA
… displaying males and the status of sage-grouse leks. Second, I used rates of WNv-induced mortality and seroprevalence from radio-marked birds to estimate rates of WNv infection. Third, I studied the influence of female characteristics, season, and environmental variables on nest, brood, and …

CONNECTING TO THE MAURI OF THE MOANA: Using a community-based, intuitive and qualitative ecological monitoring process to connect with and consider the mauri of local marine ecosystems
… (IK) and other local ecological knowledge (LEK), few challenge the dominance of Western scientific ecological knowledge (SEK) or its onto-epistemic underpinnings. Within co- management relationships this reinforces colonial power dynamics, potentially creating a barrier to the success of …

Greater Sage Grouse on the Edge of Their Range: Leks and Surrounding Landscapes in the Dakotas
… and historically active greater sage grouse leks in North Dakota and South Dakota was studied during 2001 and 2002 in an attempt to find reasons for desertion of once thriving leks and for apparent population declines. I collected information on current and historic (i.e., leks with 0-years) …

The ecology of translocated greater sage-grouse in Strawberry Valley, Utah
… effort, flocking with resident grouse, and lek attendance. We used Program MARK to calculate annual survival of translocated females in the first year after release, which averaged 0.60 (95% CI = 0.515-0.681). Movements of translocated females were within current and historic sage-grouse …

Variation in predator communities and anti-predator behaviors of Milne-Edwards' sifakas (Propithecus edwardsi) in southeastern Madagascar
… I investigated local ecological knowledge (LEK) of carnivore ecology in communities 0–20 km from continuous forest to explore the potential for such recolonization. My findings from 182 interviews in 17 communities suggest that the fossa is especially sensitive to anthropogenic disturbance; …

The Role of Male Vocal Signals During Male-Male Competition and Female Mate Choice in Greater Prairie-Chickens (<i>Tympanuchus cupido</i>)
… for discrimination among individuals. In the lek-mating Greater Prairie-Chicken (<i>Tympanuchus cupido</i>), male vocalizations are an integral part of the ritualized display. We investigated whether variation among vocal characteristics of individual male Greater Prairie-Chickens plays a role …
