(Halifax, N.S. : Saint Mary's University, 2016)Meliniomyces variabilis Hambleton and Sigler is a fungal partner of the Ericaceae, forming ericoid mycorrhizal symbioses, and a member of the Rhizoscyphus Ericae Species aggregate. M. variabilis has been isolated from a ...
-
(Halifax, N.S. : Saint Mary's University, 2016)Chemical contamination of roadside vernal breeding pools threatens amphibian abundance and diversity. Deicing compounds from roads in northern latitudes are the primary cause of contamination in spring, coinciding with ...
-
(Halifax, N.S. : Saint Mary's University, 2016)Particleboard is known to cause broader environmental issues when large amounts are sent to the landfills. The toxic adhesive resin urea formaldehyde, used to bind the wood fibers, causes contamination of groundwater in ...
-
(Halifax, N.S. : Saint Mary's University, 2013)Because of world-wide declines in amphibian populations, it is important we have a strong understanding of what features are most important to their distribution. In Chapter 1, 100 wetlands and adjacent upland habitat were ...
-
(Halifax, N.S. : Saint Mary's University, 2017)In recent studies, it has been observed that genes that have been duplicated during the course of vertebrate evolution are overrepresented among those genes that cause Mendelian diseases. My objective was to determine ...

(Halifax, N.S. : Saint Mary's University, 2011)In 2007, Anguillicoloides crassus, an invasive, parasitic nematode found in the swimbladder of anguillid eels was documented for the first time in American eel in Canadian waters, including two sites in Cape Breton (CB) ...
-
(Halifax, N.S. : Saint Mary's University, 2019)To survive, fish must maintain ionoregulatory and osmoregulatory homeostasis during changes in environmental salinity. In hypersaline water, fish must actively excrete salts and drink water to counterbalance the passive ...
-
(Halifax, N.S. : Saint Mary's University, 2022-04)Industrial whaling in the early to mid 20th century severely depleted the population of blue whales in the North Atlantic. Due to this reduction in population it is likely that the current population of blue whales in ...
-
(Halifax, N.S. : Saint Mary's University, 2020)Antibiotic resistance is becoming an increasing problem in global health. The emergence of antibiotic-resistant bacterial and fungal infections is expected to increase over the next few years. In an effort to develop ...
-
(Halifax, N.S. : Saint Mary's University, 2020)Collagen is a fibrous structural protein that possesses a characteristic triple-helical conformation which aids in the stabilisation of molecular confirmations. For example, in tissues collagen aids in maintaining the ...
-
(Halifax, N.S. : Saint Mary's University, 2014)Begging in passerine birds is an honest signal of nestling hunger to the parents. Over the breeding season a decrease in food availability and parental provisioning and an increase in parasite abundance occur suggestive ...
-
(Halifax, N.S. : Saint Mary's University, 2022-04-25)Nova Scotia has a long history of gold mining dating back to the mid-1800’s. Early mining techniques depended on the use of liquid mercury (Hg). As there were little or no environmental regulations at the time, over ...
-
(Halifax, N.S. : Saint Mary's University, 2021)Tidal marshes have the ability to sequester and store atmospheric CO2 and thus contribute a valuable ecosystem service. Globally, tidal marshes have declined due to environmental damage and habitat conversion& ...
-
(Halifax, N.S. : Saint Mary's University, 2014)Medium Density Fiberboard (MDF) is a material commonly used to construct furniture and is an engineered product made up of wood particles bonded with the adhesive resin, urea-formaldehyde. In the presence of the resin, MDF ...
-
(Halifax, N.S. : Saint Mary's University, 2016)Fine roots are ephemeral roots < 2 mm in diameter that are frequently replaced during fine root turnover. As fine roots harbour symbiotic and commensal fungi, their trophic strategy may shift upon fine root senescence and ...
-
(Halifax, N.S. : Saint Mary's University, 2020)Microorganisms play important roles in plant growth and development. The use of biofertilizers for crop production is not only beneficial to the plants but can serve as a form of sustainable agriculture. Volatile Organic ...
-
(Halifax, N.S. : Saint Mary's University, 2017)Tetraploid plant species are preferred in certain agricultural cases over their diploid counterparts for larger biomass and increased resistance to abiotic stresses. Naturally occurring tetraploids are thought to result ...
-
(Halifax, N.S. : Saint Mary's University, 2016)Anthropogenic disturbances are known to induce stress in a variety of rban species. This study aims to determine if one particular disturbance, ambient urban noise, influences the stress levels of nestling European Starlings ...
-
(Halifax, N.S. : Saint Mary's University, 2013)Nova Scotia’s coastal barrens are comprised predominantly of heathlands, a globally threatened community type. Coastal barrens provide habitat for a number of nationally rare species. Despite their ecological and cultural ...
-
(Halifax, N.S. : Saint Mary's University, 2017)Green roofs are being introduced and installed in varying climates worldwide to benefit from green roof services. Services of thermal cooling and stormwater capture reduce building energy consumption and strain on ...
