The Implications of the Emerald Ash Borer (Agrilus planipennis) on Riparian Canopy Cover in Three Halifax Regional Municipality Parks
(2020-04)Invasive species are posing an increasingly large threat to Canada’s urban forest. The Emerald Ash Borer (EAB) is an invasive pest with the potential to eliminate entire ash stands. The EAB was discovered in Nova Scotia ... -
Modelling the Critical Habitat of the Bicknell’s Thrush in the Cape Breton Highlands
(2020-04)Bicknell’s Thrush (Catharus bicknelli) is listed as a threatened species under SARA, and identification of critical habitat is a key priority in the species’ recovery. LiDAR data was used to create a habitat suitability ... -
Comparing the Richness of Pathogens around Open-Net Atlantic Salmon Marine Aquaculture Farms to Fallow Farms and Non-Farm Areas in Passamaquoddy Bay, New Brunswick: An Analysis of Methods and Proposal of Future Sampling Considerations
(2020-04)The Committee on the Status of Endangered Wildlife in Canada considers Atlantic salmon (Salmo salar) in the outer Bay of Fundy to be endangered. Despite decreases in fishing pressure since wild Atlantic salmon were ... -
Baseline Monitoring for Determining the Effects of Streetscaping on Particulate Matter Concentrations in the Downtown Area of Halifax, Nova Scotia
(2020-04)Anthropogenic sources of air pollution in cities primarily originate from automobile traffic. Understanding the extent of air pollution from traffic is important for how governments plan cities, and for maximizing the ... -
Emerging Hot Spot Analysis and Forests: A Case Study on the Hemlock Woolly Adelgid’s Invasion into Nova Scotia using Fine Spatial Resolution Satellite Imagery.
(2020-04)Adelges tsugae (hemlock woolly adelgid) is an invasive forest insect first identified in Nova Scotia in 2017. This insect poses a threat to the Acadian Forests, as Tsuga canadensis (eastern hemlock) is a keystone species ... -
A Critical Evaluation of Old-Growth Forest Definitions in Canada
(2020-04)Old-growth forests are a precious resource. As critical areas of biodiversity, they provide habitat for many species at risk. They also provide a multitude of ecosystem services and have enormous intrinsic biological ... -
Fate of Heavy Metals in Passive Wastewater Treatment Systems of the Northwest Territories
(2020-04)Due to unique climatic, geologic, and biologic conditions of northern Canadian landscapes, wastewater management in this region is complex and geographically distinctive. Many regions of the Northwest Territories (NWT) ... -
CENTRAL SCOTIAN SLOPE STABILITY: THE POSSIBLE ROLE OF GAS HYDRATES
(2002-04-15)Gas hydrates are ice-like solids in which large quantities of methane are trapped in a solid phase as a result of suitable pressure and temperature conditions in the presence of an excess supply of methane gas. They are a ... -
Minor Folds in Coticule Layers and Their Relationship to Regional Fold Evolution, Central Meguma Terrane, Nova Scotia.
(2000-04-15)The highly anisotropic turbidite sequences of the Meguma Group in southern Nova Scotia are folded into upright, noncylindrical, northeast-southwest trending box and chevron folds. Minor folds are well-developed in ... -
"Pock Marks" in Nearshore Sands: Observations During Sandyduck97.
(2000-04-15)Previous bedform research has described different ripple types forming in varying hydrodynamic conditions and used ripple geometry within sedimentary rocks to infer the paleoenvironmental conditions during the ripple ... -
