An emerging strategy for managing natural resources such as Canada’s forests more sustainably and responsibly is to use knowledge of how Mother Nature has done it to help guide our hand. This so-called ‘ecosystem-based” approach has gained favour with provincial and federal governments, as well as national and international certification agencies. One of the foundations […]

Low impact development (LID) technologies are increasingly part of the urban landscape for Canadian municipalities. Bioretention planters, also known as rain gardens, are an LID technology that infiltrates and filters runoff at the source. Though design guidance exists, there is little data available on the long term performance of LID technologies, such as bioretention systems. […]

This project will provide characterization of two strains of Pseudomonas spp. for the use of plant growth promotion. The project will accomplish this through direct field trials in order to show the benefits of these strains when inoculated on canola. We wish to explore/demonstrate other key features of these organisms such as bioremediation hydrocarbons and […]

Salt marshes are important coastal ecosystems because they provide many services to surrounding areas. Due to the high fertility of salt marsh soil, they have a long history of being converted to farmland in Maritime Canada. In recent years, there has been growing interest in restoring salt marshes to protect against coastal erosion, mitigate sea […]

Declines in migratory bird populations have been linked to a range of complex environmental factors, including the dramatic increase in application of neurotoxic neonicotinoid insecticides in recent decades. Neonicotinoids are used as seed treatments in a wide variety of Canadian crops, and consumption of treated seeds could result in poor navigation and migration delays in […]

Ce projet de recherche vise à développer un procédé innovant pour répondre à une problématique de traitement des eaux usées à laquelle font face les centres de traitement en Amérique du nord. Les variations climatiques saisonnières limitent les capacités de traitement du procédé conventionnel de lagunage en termes de volume de traitement et de réduction […]

Alewife (Alosa pseudoharengus) is a key species in the ecology of the upper Bay of Fundy, Canada, that provides food to numerous predators and scavengers. Each year, Alewife migrate into freshwater systems to spawn in lakes. Dams and fishways often impede the migration of Alewife, which can have detrimental effects on Alewife populations, as well […]

In the coming months, a new set of energy efficiency targets called “step codes” will be incorporated into the standards used to build houses. The step code is intended to provide builders with a better understanding of what is expected of them when they build energy efficient homes. It will also allow municipalities incorporate energy […]

Ce projet vise le développement d’un Indice de Qualité d’Habitat (IQH) du saumon basé sur une classification de faciès d’habitats à partir de photos aériennes récentes. L’approche repose sur 1) la modélisation et la cartographie à grande échelle de la bathymétrie et de la vitesse de l’écoulement sur des rivières à saumon types du Québec, […]

Les rejets de certaines mines en exploitation peuvent représenter un risque pour l’environnement. Les compagnies minières doivent se soumettre à différentes directives environnementales imposant une limite à la quantité de polluants rejetés dans leurs effluents. L’arsenic (As) est l’un de ces polluants. Il est libéré lors de l’extraction de divers métaux ayant une valeur commerciale. […]

La pêche sportive au saumon Atlantique est une importante industrie dans l’est du pays. Ce projet contribuera à améliorer une méthode de modélisation de l’habitat du saumon Atlantique, plus particulièrement en ce qui a trait aux nourriceries des tacons (saumons juvéniles). Les modèles d’habitat sont des outils mathématiques permettant d’évaluer quantitativement la quantité de l’habitat […]

The scope of this project is to use acoustic data from long-baseline arrays of hydrophones to detect, locate, and track marine mammals based on their vocalization. Specifically, the project aims to assess methods and develop automated tracking algorithms that provide accurate results for individual signals, and a maximum of flexibility regarding the channel, array, and […]
