Feasibility study of ultrasound application for water chestnut (Trapa natans L.) management in Lake Champlain
Water chestnut (Trapa natans L.), an annual aquatic plant with floating leaves was first introduced into North America in 1874. Since then, wild populations have quickly become established in many locations within Northeastern USA. Due to its detrimental effects on the overall health of aquatic ecosystems, millions of dollars have been spent to control the water chestnut infestations in the North America through mechanical harvesting and manual removal, with limited success.
An estimated 40% of the 48 exotic species in Lake Champlain whose invasion route is known arriaved via a canal. To manage the risk posed by the Champlain Canal, it is important to understand the nature of the risk. The goal of this project is to determine the taxon-specific risk posed by the Champlain Canal for transmitting new exotic species into Lake Champlain.
Non-native alewife and native rainbow smelt in Lake Champlain: a modeling approach to describe interactions and system-wide consequences
In the past, rainbow smelt have been the main forage fish supporting the salmonid and walleye sport fisheries in Lake Champlain. With alewife now established in the lake, an epilimnetic larval fish predator has been added to the system that can change the seasonal dynamics of young-of-year rainbow smelt by increasing mortality during the summer. We need to understand the consequences of adding such a predator to Lake Champlain.
