Habitat use and early marine ecology of juvenile (age-.O) Pacific salmon (Oncorhynchus spp.) were studied monthly at inshore, strait, and coastal habitats along a seaward migration corridor in southeastern Alaska from May through October 1997-99. A total of 31 ,853 fish from 40 taxa were captured with 283 surface trawl hauls; juvenile salmon made up 61 % of the total catch. Predation on juvenil...

Understanding why some hybrid zones are bimodal and others unimodal can aid in identifying barriers to gene exchange following secondary contact. The hybrid zone between the grasshoppers Chorthippus brunneus and C. jacobsi contains a mix of allopatric parental populations and inter-mingled bimodal and unimodal sympatric populations, and provides an ideal system to examine the roles of local sel...

The overall goal of this project is to improve our understanding of beaked whale distribution and foraging behavior and to describe inter-specific differences. We are developing habitat models for multiple beaked whale species in the Southern California Bight using passive acoustic encounters. Data from line transect surveys and autonomous recorders are compared with dynamic and static oceanogr...

Diversity of rodents were compared in a priority site conservation southern-central Chile through two seasons (winter and spring). Through the use Sherman traps, richness abundance species present both (native forest) its adjacent habitat (commercial plantation Eucalyptus globulus) was assessed. There significant differences terms diversity between habitats, composition only for case native for...

Increased awareness of spatiotemporal variation in species interactions has motivated the study of temporally-resolved food web dynamics at the landscape level. Empiricists have focused attention on cross-habitat flows of materials, nutrients, and prey, largely ignoring the movement of predators between habitats that differ in productivity (and how predators integrate pulses in resource availab...

Greater sage-grouse (Centrocercus urophasianus) are in decline across western North America. Identifi cation of management strategies to enhance populations, such as predator management, may be needed to reduce further declines, but unintentional eff ects associated with increased human activity should also be considered. We evaluated the eff ect of 3 levels of predator management eff ort on gr...
