Yellowstone Lake Acoustic Biotelemetry Project Home Page

Fishery biologists and managers are increasingly consumed with the recovery and restoration of native trout and salmon throughout the western United States. These fish historically inhabited a variety of freshwater habitats, but have declined due to habitat degradation, fragmentation and introduction of nonnative species. Introduced fishes constitute a major threat to the persistence of native...

Developing stream temperature networks for the Greater Yellowstone to aid in managing aquatic resources under a changing climate

The topographic diversity and extensive area of protected public land within the Greater Yellowstone demonstrate the importance of this region as a natural resource reserve. Understanding the effects of anticipated changes in climate on aquatic resources and means for managing these resources will ultimately require accurate linkages between empirical data and regional climatic patterns.

Evaluating the linkages between regional climate patterns, local climate data, and native Yellowstone cutthroat trout (Oncorhynchus clarkii bouvieri) and non-native brook trout (Salvelinus fontinalis) growth, survival, and life-history expressions.

Beyond large-scale climate models, it is becoming increasingly important to quantify how regional climate patterns link with in situ stream temperatures and hydrologic regimes and concomitantly, fish behavior, growth, and survival. Here, we are using comprehensive mark-recapture techniques to evaluate how changing climatic conditions are likely to influence native westslope cutthroat trout and...
