Provost Lecture Series: Impacts of invasive species in freshwater ecosystems


Biological invasions have been attracting more attention in recent years. However, invasive species are not a new problem; historically, they have been transported to different geographical locations around the globe.

Freshwater and marine ecosystems are easily accessible areas that allow for invasive hitchhikers to reach a new geographical area either deliberately or unintentionally. This will be the focus of the next Provost Lecture Series at Austin Peay State University.

Angelina D. Fowler, an adjunct instructor in the APSU Center of Excellence for Field Biology, will present “Homogenization of Earth: Impacts of Invasive Species in Freshwater Ecosystems” from 3-4:30 p.m., Thursday, Oct. 27 in the Morgan University Center, Room 303. All presentations in the Provost Lecture Series are free and open to the public.

Fowler said through exponential human population growth and technology, the spread of invasive species will never subside.

“International trade, in particular, allows these organisms to be transferred across the world, surpassing geographical barriers that they have been isolated from for millions of years,” she said.

Fowler also will discuss a brief preliminary synopsis of her thesis research over the effects of an invasive aquatic plant on macroinvertebrate communities in the Obed Wild and Scenic River national park.

Fowler received her B.S. in biology in 2009 from APSU, where she teaches general biology as an adjunct instructor. She also is a research assistant in the Center of Excellence for Field Biology. She is a master’s candidate in biology at APSU. She also has participated in a number of studies through the Center of Excellence for Field Biology.

The Provost Lecture Series seeks to foster a spirit of intellectual and scholarly inquiry among faculty, staff and students. The program will be used as a platform for APSU faculty members who are recent recipients of provost summer grants, who have been awarded faculty development leaves and who have engaged in recent scholarly inquiry during sabbatical leaves.

APSU faculty members with recent research of acclaim also will be given a platform within this series. In addition, other faculty members of local or widespread renown will be invited to lecture within this series.
