Trends in grouse research

Biological research on birds of the grouse family has become increasingly related to conservation. We review trends in grouse biology, analysing the representation of species and topics in the titles of 2,788 papers published since 1930. Ruffed grouse Bonasa umbellus, the most frequently studied species before 1960, was overtaken by willow ptarmigan Lagopus lagopus in the 1970s, after which bla...

Sage-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...

Conservation status of grouse worldwide: an update

This paper provides an overview of conservation status and major threats to grouse based on information collected by the IUCN/SSC BirdLife WPA Grouse Specialist Group during 2004-2005. At the time of compiling the first Grouse Action Plan (Storch 2000b) in 1999, no grouse species were considered to be threatened following the IUCN criteria, but three species with limited geographic distribution...

Grouse: Feature-Based, Steerable Graph Hierarchy Exploration

Grouse is a feature-based approach to steerable exploration of a graph and an associated hierarchy. Steerability allows exploration to begin immediately, rather than requiring a costly layout of the entire graph as an initial step. In a feature-based approach, the subgraph inside a metanode of the graph hierarchy is laid out with a wellchosen algorithm appropriate for its topological structure....
