Seabirds share many characteristics setting them apart from other birds. The amount and pattern of cutting in a landscape that extends across a region will have less effect than the same amount and configuration in a landscape type that is confined to a small locale. The group studies species living in fragmented landscapes and attempts to advance metapopulation ecology research. We found a strong association between the lower elevation limits of bull trout distributions and longitude and latitude; this association was consistent with the patterns in mean annual air temperature. The rescue effect may lead to alternative stable equilibria in metapopulation dynamics.

The WDNR initiated a wild trout stocking program in to improve the quality of hatchery-reared brook and brown trout by raising offspring of wild parentage. This problem might be addressed by providing stable areas in which populations dependent on woody detritus are kept high and can serve as sources to the surrounding, lower quality, and shifting hab Davies - Biological Conservation , Single species metapopulation dynamics:

We concluded that climate does strongly influence regional and local bull trout distributions, and we estimated bull trout habitat response to a range of predicted climate warming effects. Future research will address habitat limitations to survival and reproduction of stocked wild trout and the long-term viability of source populations for the wild trout stocking program. Habitat destruction and competitive coexistence. Research questions have changed little over time; the same problems examined in the s are still being addressed. Analysis of DNA sequence variation. Preliminary analyses indicated survival rates times greater for stocked trout of wild versus domestic parentage, and some increases in natural reproduction have been observed.
