N2 - Aquatic plants represent a key target in the management of biological invasions due to their ability to outcompete native
species, interfere with human water use, and modify nutrient cycles. Studying desiccation tolerance of aquatic plants can
improve understanding of their survival in habitats with fluctuating water levels, as well as response of invasive aquatic
plants to management practices such as drawdowns. In a preliminary study, using Hydrilla verticillata as a case study, we
desiccated plant fragments for 3 hours on top of sediment, buried beneath sediment, and in the absence of sediment in
laboratory mesocosms to quantify the effects of sediment burial on survival and growth upon reintroduction to a common
aquatic environment. In the absence of sediments, fragments experienced the greatest mass loss during desiccation and
highest mortality rates upon reintroduction to the aquatic environment. Burial decreased plant fragment mass loss during
desiccation, and upon return to a
