    Population dynamics of the Devils Hole pupfish

    Full text link
    A model is constructed to simulate fluctuations in monthly population sizes of the Devils Hole pupfish between January 1973 and August 1976. A variety of biological parameters is estimated, and adult mortality is partitioned into natural and environmentally-dependent components. The simulations capture the seasonal fluctuations in population size, and only seven predicted population sizes differ from those observed by 20% or more. The model is used to make testable predictions about the life history of this species and interactions of the parameters are discussed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/42634/1/10641_2004_Article_BF00002582.pd
