Duckweed In Wastewater Management: Species Comparison Of Spirodela Polyrhiza And Lemna Minuta, Lindsey Chepalonis Jan 2023

Duckweed In Wastewater Management: Species Comparison Of Spirodela Polyrhiza And Lemna Minuta, Lindsey Chepalonis

Student Research Poster Presentations 2023

Wastewater is any liquid or water-carried waste accrued from sanitary operations. This waste contains toxins that must be purified, as they pose an environmental and public health hazard. Specifically, this risk is high in developing countries. Aquatic plants can be used to purify wastewater. Duckweed is a free-floating aquatic plant with over 37 species, but Lemna minor is typically used for wastewater management. This research focuses on finding different species to use in wastewater management. Spirodela polyrhiza and Lemna minuta chlorophyll concentration and frond increase were compared with Lemna minor. The species were maintained in varying concentrations of Hoagland’s solution …


Effects Of Invasional Meltdown On Community Structure In Marine Ecosystems In The Damariscotta Estuary Of Maine, Kate Lazzeri Jan 2021

Effects Of Invasional Meltdown On Community Structure In Marine Ecosystems In The Damariscotta Estuary Of Maine, Kate Lazzeri

Student Research Poster Presentations 2021

Basibiont organisms form the foundation of marine ecosystems by providing additional space for new species to settle on as epibionts. Invasive epibionts may take advantage of this new basibiont presence, which leads to many harmful effects on native organisms such as competition for both resources and food. In some cases, invasive species facilitate recruitment of other invasive organisms, a phenomenon referred to as invasional meltdown, but it is not known if invasion of new basibionts increases invasive epibiont occurrence. The purpose of this study is to answer the following research questions: 1) does the invasion status of the basibiont alter …
