Temporal habitat partitioning and resource competition between congenerics: Testing for density-dependent growth and mortality in estuarine shrimp.

ABSTRACT: Habitat partitioning can promote coexistence of closely related competitors. Two congeneric shrimps (brown shrimp, Penaeus aztecus, and white shrimp, Penaeus setiferus) which utilize estuaries in the southeastern U.S. temporally partition much of their nursery habitat occupancy but also experience a period of overlap at the respective tails of their nursery residency. Throughout nursery residency, when conspecific or congeneric abundance can be high, density-dependent (D-D) processes may alter demographic rates, but the relative importance of the potential biotic interactions occurring in these habitats (e.g., intra- and inter-specific competition, cannibalism, among others) remains underexplored. Here, we documented the periods of nursery habitat use for these two penaeid shrimp species w
