Population characteristics of the barnacle Balanus eburneus were analyzed with the purpose of exploring its potential use as a discriminating indicator among sites exhibiting different disturbances or stages of recovery. The study was conducted from May 2012 to May 2013 at four estuaries in the Lower Laguna Madre, TX including a) Bahia Grande, currently under restoration and divided into Bahia Grande North and Bahia Grande South, b) San Martin Lake, which receives runoff water and c) South Bay, a relatively undisturbed reference estuary. In general, similar barnacle recruitment and growth trends in Bahia Grande South and South Bay were explained by comparable environmental parameters that included temperature, salinity and water clarity. Isotopic analysis provided time-integrated information of seasonal changes in resources and trophic relations. Results indicate barnacle population metrics discriminate among sites and that Bahia Grande South is transitioning towards a more stable ecological status comparable to the reference site.
