Macro-invertebrate assemblages of central Texas coastal bays and Laguna Madre

A study of the distribution of macrofauna and the ecological factors affecting their distribution in the bays and lagoons of the central and south Texas coast has made it possible to formulate a series of criteria for interpreting modern and ancient depositional environments. The observations reported in this paper cover a 7-year period. In addition, some information was available covering a period of 30 years. The central Texas bays are situated in a variable climate, and the faunas reflect long-term changes in rainfall and temperature.
