Population estimates for the peregrine falcon in Arizona: A habitat inventory approach Population estimates for the peregrine falcon in Arizona: A habitat inventory approach
At least 50 pairs of peregrine falcons reside in Arizona. From aerial surveys of available habitat and occupancy trends at more than 600 sites searched from 1975 to 1985, we estimated that at least 90 pairs resided in the study area. We project a fully recovered population of at least 190 pairs.

Raptors and aircraft Raptors and aircraft
Less than 5% of all bird strikes of aircraft are by raptor species, but damage to airframe structure or jet engine dysfunction are likely consequences. Beneficial aircraft-raptor interactions include the use of raptor species to frighten unwanted birds from airport areas and the use of aircraft to census raptor species. Many interactions, however, modify the raptor?s immediate behavior...

Riverine C, N, Si and P transport to the coastal ocean: An overview Riverine C, N, Si and P transport to the coastal ocean: An overview
Terrestrial ecosystems cycle and recyle inorganic nutrients including a feedback to atmospheric dry deposition and precipitation (cf. Lewis et al., 1985). Each year, however, a small fraction per unit area of the atmosphere/plant/soil flux leaks from these land-based cycles via precipitation/runoff (Meybeck, 1982). These losses are, in general, unpreventable. Moreover, such nutrient...
