Assessing the risk of dreissenid mussel invasion in Texas based on lake physical characteristics and potential for downstream dispersal


September 2016 - September 2017


Zebra mussels were first reported in Lake Texoma (Texas/Oklahoma) around 2009, and have since spread further into the state. Delimiting suitable dreissenid habitat and dispersal potential within Texas represents a critical management need. The objectives of this study are to assess risk of zebra mussel (Dreissena polymorpha) and a related invasive species, quagga mussel (Dreissena bugensis) invasion in Texas by 1) predicting general distribution of suitable habitat in Texas using Maxent models; 2) refining lake-specific predictions via collection of physicochemical data from identified high-risk lakes; and 3) assessing the potential for downstream spread of zebra mussels with environmental DNA.
