COASTAL ECOLOGY & GENETICS LAB

Estuaries and barrier islands are beautiful, dynamic, and complex ecosystems. Understanding the driving forces and interplay among species is a fundamental goal of our lab.  We use a combination of experimental and observational approaches. We apply advanced multivariate statistical analyses such as Structural Equation Modeling to explore hypotheses. Learn more about our research and areas of study below.

 

We are broadly interested in assessing plant and animal populations and assemblages in intertidal and shallow subtidal systems and the effects of changing climate on these systems. Projects are primarily in Texas and Florida, and we have close ties with mangrove researchers in China. Genetic evaluations of mangrove connectivity and diversity has spanned the Caribbean and links also to west Africa. Some example programs are illustrated below. PROSPECTIVE STUDENTS, please consider the Texas A&M - Corpus Christi Marine Biology MS or PhD programs; or the Biology MS program; or the Fisheries & Mariculture MS program.  http://sci.tamucc.edu/LSCI/MARB/index.html
