We tested the hypothesis that spawning-bed enhancement increases survival and growth of chinook salmon (Oncorhynchus tshawytscha) embryos in a regulated California stream with a gravel deficit. We also examined how 12 physical parameters...

Hypersaline lakes are noted for their simple communities which facilitate understanding ecological interactions (Williams et al. 1990; Wurtsbaugh 1992; Jellison and Melack 1988). Nevertheless, we still cannot easily predict how environmental...

The growth of age-0 Arctic grayling Thymallus arcticus in two adjacent watersheds with differing numbers of lakes was compared. Age-0 Arctic grayling grew faster in the watershed with numerous lakes (eight) than in the watershed with only one...

High-elevation red spruce (Picea rubens Sarg.) – Fraser fir (Abies fraseri (Pursh) Poir.) forests of the southern Appalachians exhibit considerable spatial heterogeneity in structure, and possibly in N uptake, because of a combination of natural...

Diel changes in the distribution of the tidewater silverside ( Menidia beryllina) and its prey were measured in Clear Lake, California, a large, shallow, eutrophic lake. Zooplankton prey densities were low in the littoral zone, but increased...

Geomorphic systems are known to exhibit nonlinear responses to physical–biological feedbacks (Thornes, 1985, Baas, 2002, Reinhardt et al., 2010). These responses make understanding and/or predicting system response to change highly challenging....
