Movements of mountain whitefish (Prosopium williamsoni) in the Sheep River were studied during 1972 and 1973. Movement patterns of young-of-the-year and immature whitefish are ill-defined. Although some adult mountain whitefish are nonmigratory, the majority are migratory and show complex movement patterns including spring feeding, summer feeding, prespawning, spawning, and postspawning-overwintering movements. Environmental factors affecting and/or controlling these movements are discussed.

Species Responses

Species responses to grazing and environmental factors were studied in an arid halophytic shrubland community in Western Australia. The grazing responses of major shrub species were defined by using reciprocal averaging ordination of botanical data, interpreted in conjunction with a similar ordination of soil chemical properties and measures of soil erosion derived from large-scale aerial photographs. An apparent small-scale interaction between grazing and soil salinity was also defined. Long-term grazing pressure is apparently reduced on localised areas of high salinity. Environmental factors affecting species distribution are complex and appear to include soil salinity, soil cationic balance, geomorphological variation and the influence of cryptogamic crusts on seedling establishment.
