Spatial Assessment of a Biocriteria Applied to Texas Tidal Streams

Table 5

Relative contribution of each taxa (% of total, by study) to at least 95% of the overall community structure as measured by midchannel otter trawls during the summer season. Dashed lines represent contributions of ≪1.0%; empty cells represent taxa not encountered during summer sampling.
