The natural sediment geochemistry of estuaries makes them vulnerable to bioaccumulation of methylmercury (MeHg), a neurotoxin that bioaccumulates in organisms. Intertidal invertebrates are abundant in estuaries and are critical prey sources for migratory birds and fish. Determining uptake of MeHg by invertebrates...

Insect pests present a significant threat to global economies through crop damage and causing adverse effects on human health. Synthetic pesticides are most often used to control insect pests. However, the long-term and extensive use of synthetic pesticides can impact human health,...

Background As the global population increases, demand is also increasing for food production methods that involve efficient use of resources and do not require large expanses of arable land. Aquaponics is a method that incorporates growing crops under soilless conditions (hydroponics) in...

Biovectors can transport contaminants to remote locations through excretion, shedding feathers and decomposition of carcasses. Big Meadow Bog on Brier Island is home to nearly 3000 mating pairs (2019) of herring gulls (Larus argentatus) each year during their nesting season (April-August). Mercury...
