(Halifax, N.S. : Saint Mary's University, 2021)Habitat fragmentation and habitat loss are two of the largest threats to biodiversity in the modern age. Because of this, the study of how animals move between patches of fragmented habitats is crucial to being able to ...
-
(Halifax, N.S. : Saint Mary's University, 2021)Saint Lucia, like many other Caribbean islands have not had consistent coastal monitoring programs. This research looks into coastal risk and vulnerability associated with sea level rise and anthropogenic climate change ...
-
(Halifax, N.S. : Saint Mary's University, 2019)Historical gold mining in Nova Scotia resulted in over 3,000,000 tonnes of mine tailings deposited into aquatic habitats and low-lying areas, where they remain today. Legacy tailings are typically elevated in mercury (Hg) ...
-
(Halifax, N.S. : Saint Mary's University, 2015)The environmental increase of mercury and arsenic - two contaminants with no biological functions - due to anthropogenic activities is a complex and growing issue. Both mercury and arsenic, in particular methylmercury and ...
-
(Halifax, N.S. : Saint Mary's University, 2017)Understanding characteristic hydrology is the first step toward assessing the degree of impairment in any wetland, including peatlands, and developing an effective approach for restoration. Pre-disturbance datasets are ...
-
(Halifax, N.S. : Saint Mary's University, 2016)The atmosphere is very complex and it involves many chemical and physical processes that affect the air people breathe. This is why it is important to characterize the air in the atmosphere in order to determine what people ...

A comparison of native and novel ecosystems : green roof impacts on plant growth and pest abundance (Halifax, N.S. : Saint Mary's University, 2016)There is little research that supports the potential of green roofs to provide biodiversity similar to ground-level habitat. This study examined three hypotheses. (1) Due to the similarities in environmental stresses, ...
-
(Halifax, N.S. : Saint Mary's University, 2021)High concentrations of tropospheric ozone are a concern due to its detrimental effects on human and plant health. As the world population expands and ozone precursor emissions become more challenging to limit, understanding ...
-
(Halifax, N.S. : Saint Mary's University, 2018)Atmospheric ozone (O3) is a secondary pollutant produced via complex chemical reactions involving precursors like nitrogen oxides (NOx), Volatile Organic Compounds (VOC) and carbon monoxide (CO). The ...
-
(Halifax, N.S. : Saint Mary's University, 2022-04-28)The Tekes River alluvial fan is located in Xinjiang Province which has an arid to semi-arid climate as well as a historically unpredictable precipitation rate. Further, increasing population and urbanization means that ...
-
(Halifax, N.S. : Saint Mary's University, 2017)Alkaline hydrothermal vents provide a variety of chemical reagents and conditions that may provide insight as to how life emerged on Earth. This study examined small molecule chemistry under conditions found at these vents. ...
-
(Halifax, N.S. : Saint Mary's University, 2020)The Chinese mystery snail, Cipangopaludina chinensis, is a non-indigenous, potentially invasive aquatic species found throughout North America. They are highly fecund and viviparous, birthing live young. These features ...
-
(Halifax, N.S. : Saint Mary's University, 2023-05-03)Increased greenhouse gases in Earth’s atmosphere are altering the global climate including changes in air temperature and precipitation patterns that are linked to increasing storms and sealevel rise. In coastal regions, ...
-
(Halifax, N.S. : Saint Mary's University, 2023-04-30)Earthworms are ecosystem engineers which alter soil structure and impact other organisms and ecosystem functioning. In 2014, pheretimoid “jumping worms” (Megascolecidae spp.) were discovered in Ontario, Canada, with later ...
-
(Halifax, N.S. : Saint Mary's University, 2015)Green roofs are increasingly recognised as a sustainable option for reducing building energy demand. However, given the large investment required for their construction, accurate modelling methods are needed to predict ...
-
(Halifax, N.S. : Saint Mary's University, 2018)With a growing demand for energy, and a desire to reduce anthropogenic climate change, the use of renewable energy sources is becoming increasingly popular. A major source of renewable energy that is readily available is ...
-
(Halifax, N.S. : Saint Mary's University, 2023-08-22)Chloride-based road deicers are commonly used for winter road maintenance but can be detrimental in both terrestrial and aquatic environments. The objective of this thesis was to investigate the impacts of road salting ...
-
(Halifax, N.S. : Saint Mary's University, 2023-04-26)In the early to mid 1900s the American wetland was considered a forbidden wasteland with the purpose of being dominated by humans. This perception remained dominant throughout the first half of the century and lessened ...
-
(Halifax, N.S. : Saint Mary's University, 2019)There is a lack of research on the pollinator communities of flowering plant species within coastal barren habitats. This study examined four closely related plant species in the Ericaceae that have a similar flower ...
-
(Halifax, N.S. : Saint Mary's University, 2021)Large gaps exist in knowledge of the global patterns and drivers of biodiversity, particularly in belowground systems and island environments. Earthworms are a key group of soil invertebrates in many systems due to their ...
