Throughout North America the true armyworm (Mythimna unipuncta) occurs in sporadic large outbreaks. During these mass infestations their caterpillars cause considerable economical damage to cereal and forage crops such as barley, oats, corn, and alfalfa. Understanding the chemical ecology of the true armyworm will help develop naturally-derived agents...

Environmental monitoring during the COVID-19 pandemic can be used as a tool to identify locations of asymptomatic or pre-symptomatic carriers,  focus clinical testing, and confirm cleaning protocols. LuminUltra developed a surface testing method for the SARS-CoV-2 virus that allows for swabs of high-touch surfaces to...

During the Nova Scotia gold rush (early 1860’s to mid-1940’s), over 300 gold mines were established across the province, including several within what is today the Halifax Regional Municipality (HRM). Many of these sites were never remediated and are often found near...

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...

The two-spotted spider mite (Tetranychusurtichae)is a serious pest of greenhouse and field crops in Canada, damaging plants by feeding on the contents of leaf cells. Spider mites produce silk and use it for protection, movement, and communication. Research Question: how do spider...

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...

Old growth forests are unique, vital reservoirs of carbon, ecological continuity and genetic information. Limited and scattered fragments of old growth forests persist on private lands in the Annapolis Valley, but are not governed by provincial legislation. This project aims to locate...
