(Halifax, N.S. : Saint Mary's University, 2018)The ‘White’ Threespine Stickleback is a form of stickleback endemic to Nova Scotia, Canada, which exists sympatrically with the ‘common’ marine Threespine Stickleback. These fish differ in both morphology and behaviour. ...

(Halifax, N.S. : Saint Mary's University, 2023-04-20)Acute myocardial infarction (AMI) is a deadly disease wherein the coronary arteries become blocked, causing irreversible death to myocardial wall tissue which can result in heart failure. Current clinical methods lack the ...

(Halifax, N.S. : Saint Mary's University, 2022-04-27)Early diagnosis of Post-Traumatic Stress Disorder (PTSD) is challenging. Its prevalence rate in Canada is 9.2%. Experiencing stress for a sustained period can lead to a prolonged release of cortisol that causes negative ...
-
(Halifax, N.S. : Saint Mary's University, 2020)Most passerine species begin incubating their clutches once the penultimate egg is laid, allowing for asynchronous hatching of nestlings. This results in delayed development by 24 hours or more of the nestling hatching ...
-
(Halifax, N.S. : Saint Mary's University, 2019)Parasites can impose fitness consequences onto their hosts by reducing their reproductive success or offspring survival rates. Carnus hemapterus are external parasites that feed on the blood of European Starling (Sturnus ...
-
(Halifax, N.S. : Saint Mary's University, 2018)In parent-offspring interactions, nestlings signal their hunger to parents by begging. Parents typically respond by increasing their provisioning rate. This type of communication involves specific vocalizations, postures, ...
-
(Halifax, N.S. : Saint Mary's University, 2017)Begging by nestling passerines is an important method of communicating to parents their state of hunger. I examined whether experimentally increased nestling begging in a brood can quickly alter parental provisioning rates ...
-
(Halifax, N.S. : Saint Mary's University, 2018)Studies have shown that the most energetically costly event in a bird’s life cycle is that of breeding, particularly for females who lay nutrient-rich eggs. Studies also show that older males and females are often preferred ...
-
(Halifax, N.S. : Saint Mary's University, 2021)Nestlings of most passerine species face many stressors including early exposure to ectoparasites. Ectoparasites negatively impact the health of nestlings by feeding on their blood and feathers, leaving the nestlings ...
-
Drug overdose deaths in Halifax, Nova Scotia from 1996 to 2010 : a descriptive and comparative study (Halifax, N.S. : Saint Mary's University, 2013)Drug overdose death is an increasing concern in many areas of the world and many prevention programs exist to control these deaths. These include prescription monitoring programs, Naloxone treatment, safer injection ...
-
(Halifax, N.S. : Saint Mary's University, 2017)Heat shock proteins (HSPs) are highly conserved and present in organisms under normal physiological conditions and function in protein folding, degradation and localization. HSPs are also synthesized in response to ...
-
The effect of ectoparasite load on the condition of nestling European starlings (Sturnus vulgaris) (Halifax, N.S. : Saint Mary`s University, 2022-04-28)Nest-dwelling ectoparasites are commonplace among-cavity nesting birds such as the European starling (Sturnus vulgaris), and can be detrimental to the health of nestlings. To determine if this was also the case for ...
-
(Halifax, N.S. : Saint Mary's University, 2023-05-01)Interspecific hybridization occurs when two species successfully mate to produce offspring. This phenomenon is relatively common in nature and can produce hybrids with advantaged, disadvantaged, or intermediate physiology ...
-
(Halifax, N.S. : Saint Mary's University, 2019)The full potential of biological control agents, such as the two-spotted lady beetle, Adalia bipunctata L., against insect pests greatly depends on the ability of the control agent to successfully mature to adulthood. ...
-
(Halifax, N.S. : Saint Mary's University, 2016)Ascophyllum nodosum extract (ANE) is a processed brown seaweed extract used as a biostimulant. The known effects of ANE, when applied to plants in the aforementioned agricultural setting, include amplified plant growth, ...
-
(Halifax, N.S. : Saint Mary's University, 2018)The operational sex ratio is the number of fertilizable females to mature males in a population at a particular time. Variation in this ratio is often associated with change in behaviour during mating, including differences ...
-
(Halifax, N.S. : Saint Mary's University, 2021)Road salt is a crucial public safety tool to protect people on winter roads, but it disperses from roads and impacts the environment. Increased salinity affects both soil and water systems with adverse effects observed on ...
-
(Halifax, N.S. : Saint Mary's University, 2018)Spatially varying environments are expected to provide more niche breadth than homogeneous areas, and should thus support a larger number of plant species. The observed sample area, or spatial scale, can also influence the ...
-
(Halifax, N.S. : Saint Mary's University, 2013)Integrated Positron Emission Tomography and Computerized Tomography (PET/CT) is a powerful imaging technique that combines functional and anatomical information for early and accurate detection of cancer. Limited availability ...
-
(Halifax, N.S. : Saint Mary's University, 2018)Microsporidia are unicellular eukaryotic parasites that cause chronic diseases in invertebrates, as well as some other species in the animal kingdom, such as fishes, crustaceans and even humans. Microsporidia are known to ...
