Abstract

Myodocopid ostracods were identified from > 600 benthic samples collected from Tampa Bay, Florida, during 1995 to 2001, as part of an annual synoptic survey of the benthos. At least 24 taxa were present. Parasterope pollex was the most abundant (76%) and most frequently collected (48%) species; Rutiderma darbyi (28%) and Eusarsiella disparalis (16%) were the next most frequently collected species. Logistic regression and “center of abundance” calculations were used to identify habitat “preferences” for the most frequently occurring species. With the exception of P. pollex, these were more likely to occur in coarser sediments, in more saline waters, and at greater depths than the mean for Tampa Bay. Parasterope pollex occurred over the widest ranges of salinity and sediment types, although it preferred medium to fine sand-sized sediments; P. pollex was also the species most tolerant of low dissolved oxygen concentrations.
