The distribution of the wood boring isopod Limnoria in Texas estuaries and bays in relation to environmental factors
Typescript (photocopy). The gribble Limnoria tripunctata and other members of the family Limnoriidae annually cause millions of dollars of damage to wooden structures in the marine environment. Thus it is of considerable economic importance to understand the factors which control the distribution of...
