Genetics of local adaptation in salmonid fishes

Developmental Genetics of Adaptation in Fishes: The Case for Novelty

During the past decade of study in evolutionary developmental biology, we have seen the focus shift away from the stunning conservation of form and function between distantly related taxa toward the causal explanation of differences between closely related species. A number of fish models have emerged at the forefront of this effort to dissect the developmental genetic and molecular basis of ev...

Proliferative Kidney Disease in Salmonid Fishes

Salmonid fishes undergoing the process of smoltification

have elevated levels of thyroid hormones (Barron, 1986; Hoar, 1988; Datta et al., 1999; Eales, 1990). Thyroid hormones play a central role in controlling many of the alterations in physiology, morphology and behavior noted during this metamorphic transition in juvenile salmon (Hoar, 1988). Thyroid hormones have also been identified in altering the visual system during smoltification. During mig...

The evolutionary ecology of alternative migratory tactics in salmonid fishes.

Extensive individual variation in spatial behaviour is a common feature among species that exhibit migratory life cycles. Nowhere is this more evident than in salmonid fishes; individual fish may complete their entire life cycle in freshwater streams, others may migrate variable distances at sea and yet others limit their migrations to larger rivers or lakes before returning to freshwater strea...

Multiple forms of supernatant malate dehydrogenase in salmonid fishes.

Salmon generally possess three forms of supernatant malate dehydrogenase whose subunit compositions are indicated by the formulas AA, AB, and BB. Each of the homodimers (AA and BB) has now been purified to homogeneity. The two enzymes are similar in molecular size and in catalytic properties to the supernatant malate dehydrogenases of higher vertebrates; both are catalytically distinct from the...
