Stream pH as an abiotic gradient influencing distributions of trout in Pennsylvania streams
P.M. Kocovsky, R.F. Carline
2005, Transactions of the American Fisheries Society (134) 1299-1312
Elevation and stream slope are abiotic gradients that limit upstream distributions of brook trout Salvelinus fontinalis and brown trout Salmo trutta in streams. We sought to determine whether another abiotic gradient, base-flow pH, may also affect distributions of these two species in eastern North America streams. We used historical data...
Individual variation in staging and timing of spring migration of Pacific common eiders in Alaska
Margaret R. Petersen
2005, Conference Paper, Second North America Sea Duck Conference
Timing of migration and characterization of migration patterns of birds are usually based on dates of peak migration to and from staging, wintering, and breeding areas used by the bulk of a species. For Pacific common eiders (Somateria mollissima v-nigrum), as well as other species, the timing of migration into...
