Predation and competition play an important role in the                    structure of communities in many different ecosystems.  The                     importance of these biotic interactions in the structure of                     stream communities remains a pressing question in community                     ecology.  this question will be examined in two large arrays of                 replicated experimental streams; one of 16 streams and one of 24                streams, and in a program of field sampling and field experiments               at Mountain Lake Biological Station.  The experimental streams                  are constructed to mimic the pool an driffle habitats                           respectively of Appalacian mountain streams.  Several benthic                   species common in these streams will be used.  Etheostoma                       flabellare, Eurycea bislineata, Cottus bairdi, and Gyrinophilus                 porphyriticus, along with the midwater predator Salvelinus                      fontinalis, to assemble complex communities.  This will be the                  first large-scale in lotic ecosystems.  This program of research                will enable stream ecologists to better interpret patterns of                   distribution and abundance of species in small streams and to                   better understand the large body of data on habitat segregation                 and microhabitat use patterns in stream communities.
