Reproductive isolation and the expansion of an invasive hybrid swarm Reproductive isolation and the expansion of an invasive hybrid swarm
Biological invasions involving hybridization proceed according to prezygotic and postzygotic reproductive isolating mechanisms. Yet few comparisons of reproductive isolation have been carried out to understand how different mechanisms prevent or promote invasions involving hybridization. Here we present a study of prezygotic and postzygotic isolation between non-native red shiner...

The Gonzales-New Orleans aquifer is an important source of fresh water for southeastern Louisiana. Withdrawals from the Gonzales-New Orleans aquifer in Jefferson and Orleans Parishes totaled about 33 million gallons per day in 1990, most of which was used for power generation and industrial purposes. Ground-water flow in the Gonzales-New Orleans aquifer within the study area is toward...
