Research in Thermal Biology:
Burning Questions for Coldwater Stream Fishes
Abstract |
| With
the increasing appreciation of global warming impacts on ecological
systems, in addition to the myriad of land management effects on water
quality, the number of literature citations dealing with the effects
of water temperature on freshwater fish has escalated in the past
decade. Given the many biological scales at which water temperature
effects have been studied, and the growing need to integrate knowledge
from multiple disciplines of thermal biology to fully protect beneficial
uses, we held that a survey of the most promising recent developments
and an expression of some of the remaining unanswered questions with
significant management implications would best be approached collectively
by a diverse research community. We have identified five specific
topic areas of renewed research where new techniques and critical
thought could benefit coldwater stream fishes (particularly salmonids):
molecular, organism, population/species, community and ecosystem,
and policy issues in water quality. Our hope is that information gained
through examination of recent research fronts linking knowledge at
various scales will prove useful in managing water quality at a basin
level to protect fish populations and whole ecosystems. Standards
of the past were based largely on incipient lethal and optimum growth
rate temperatures for fish species, while future standards should
consider all integrated thermal impacts to the organism and ecosystem. |
