Ontogeny and evolution of salinity tolerance in anadromous salmonids: Hormones and heterochrony Ontogeny and evolution of salinity tolerance in anadromous salmonids: Hormones and heterochrony
Use of estuaries and oceans by salmonids varies greatly, from no use in nonanadromous species, to movement toward the sea soon after hatching and emergence in some Pacific salmon. This variation is accompanied by large differences in the ontogeny of salinity tolerance among salmonids. Some species acquire increased salinity tolerance early in development, whereas others develop this...

Duration of protection against Aeromonas salmonicida brook trout immunostimulated with glucan or chitosan by injection or immersion Duration of protection against Aeromonas salmonicida brook trout immunostimulated with glucan or chitosan by injection or immersion
Brook trout (Salvelinus fontinalis) were given the immunostimulants glucan or chitosan by single injections or by a 30‐min immersion to induce protection against the fish disease furunculosis. At 1, 2, 3, 7, 14, 21, and 28 d after immunostimulation, sublots from these groups were challenged by a 1‐min bath exposure to a 48‐h culture of Aeromonas salmonicida. All four groups showed high...

Can activity traps assess aquatic insect abundance at the landscape level? Can activity traps assess aquatic insect abundance at the landscape level?
We used activity traps as designed by Riley and Bookhout (1990. Wetlands) to sample aquatic invertebrates as part of a study to characterize wetlands on a forested and an agricultural landscape (ca. 1,000 mi'2) in northern. Maine. Eight wetlands (5 from agricultural and 3 from forested landscapes) were sampled at random from 50 wetlands surveyed for waterfowl broods. At the landscape...
