Wastewater surveillance has been applied to uncover virus outbreaks, provide information on drug consumption and vaccination uptake, and assess collective exposure to environmental stressors such as environment and food toxins. Collecting wastewater for analysis of chemicals and viruses shed by humans provides an unbiased,...

Nowhere else in the world do the threatened Fernald’s and Long’s Braya (Braya fernaldii, B. longii) find a natural home than in the Limestone Barrens of the island of Newfoundland. The goal of this project was to provide a starting point for further research by growing and...

Jessie Wilson is a Master’s student in Dr. Mark Mallory’s lab studying how microplastics move through freshwater ecosystems. Jessie’s field work is at the world famous IISD Exeperimental Lakes Area and is part of a long term microplastics study. Jessie says, “with...

The Minas Basin is a part of the Bay of Fundy. It is east of the Minas Passage and runs to Truro, Nova Scotia. The Bay of Fundy is used for aquaculture, shipping, and fishing. As such, the Bay of Fundy has...

Salt marshes are blue carbon ecosystems that accumulate and store high amounts of carbon below ground. Carbon can be accumulated from suspended sediment (allochthonous) and within the salt marsh through fixed carbon dioxide via photosynthesis by marsh vegetation (autochthonous). The carbon is...

Long’s Braya, Braya longii, is an endangered perennial plant found only in the Great Northern Peninsula of Newfoundland. It is subject to annual infestations of the Diamondback moth (DBM), Plutella xylostella, who use B. longii as hosts to lay their eggs. The larvae then defoliate and...

Insects and mites 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 such pest species. However, the long-term and extensive use of synthetic pesticides can impact...

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...
