With climate change, fish are facing rising temperatures, an increase in the frequency and severity of heat waves and hypoxia, sometimes concurrently. However, only limited studies have examined the combined effects of increases in temperature and hypoxia on fish physiology and survival. We measured the cardiorespiratory physiology of 12°C-acclimated Atlantic salmon when exposed acutely to normoxia [100% air saturation (sat.

Traditionally, the most commonly encountered Dermacentor spp. (Acari: Ixodidae) in southern British Columbia, Canada has been Dermacentor andersoni Stiles. However, with the novel detection of Dermacentor similis Lado in southern British Columbia, environmental sampling for Dermacentor spp.

Canadian veterinarians' collective experience with and clinical knowledge of imported dogs can provide valuable insights into this practice.
Objective: To describe Canadian veterinarians' experiences with, and perspectives of, imported dogs in clinical practice.
Within veterinary medical education, there is increasing focus on equity and cultural competency/humility, especially within service learning in community and shelter medicine. This article reviews the current literature and draws from the experience of the Ontario Veterinary College Community Healthcare Partnership Program's development of a community and shelter medicine curriculum. We propose that to graduate veterinarians with the knowledge and skills to address inequities in access to veterinary care, a best practice is to integrate mandatory in-class and experiential learning activities, scaffolded across the curriculum.

With the recent description of Dermacentor similis Lado in the western United States, additional research is required to determine the current range of this species. Five hundred ninety-eight Dermacentor spp.

It is anticipated that disease incidence will increase due to a warming climate, given that habitats are expanding for reservoir hosts and vectors, particularly in Canada. Little is known about the ecology of primary vectors that perpetuate these orthobunyaviruses, including the viral transmission cycle and the impact of climatic and landscape factors.
View Article and Find Full Text PDFLow-oxygen levels (hypoxia) in aquatic habitats are becoming more common because of global warming and eutrophication. However, the effects on the health/disease status of fishes, the world's largest group of vertebrates, are unclear. Therefore, we assessed how long-term hypoxia affected the immune function of sablefish, an ecologically and economically important North Pacific species, including the response to a formalin-killed Aeromonas salmonicida bacterin.
View Article and Find Full Text PDFTreats are a prevalent aspect of pet care, frequently given by dog and cat caregivers for varying reasons. However, recommendations of reducing or eliminating treat feeding poses a common challenge, leading to potential non-adherence surrounding weight management practices. To explore caregivers' perceptions and experiences surrounding treat feeding, we conducted five online focus groups with 24 dog and cat caregivers, recruited via an infographic shared on social media using snowball sampling.

Feeding practices have the potential to cause nutrient imbalances and adverse health outcomes, including obesity. The objective of this study was to identify and describe the perceptions, motivations, and behaviours surrounding treats, and factors that influence treat feeding by cat caregivers.
View Article and Find Full Text PDFObesity remains a significant concern for dogs and cats, and reducing or eliminating treats is commonly recommended as a strategy for weight management. Caregivers can struggle with adherence to such dietary recommendations. Previous research suggests caregivers are reluctant to reduce treats but there is limited understanding of the underlying factors contributing to these behaviours and decisions.

The proportion of males was greater than females. Bimodal peaks in incidence were observed in children and older adults (≥60 years of age) for all clinical signs except cardiac manifestations, which were more evenly distributed across age groups.

This study is the first to estimate the number of dogs imported into Canada and describe spatial and temporal trends.
Animal And Procedure: Commercial and a subset of personal dog importation records, obtained from the Canada Border Services Agency, were used to estimate the total number of dogs imported into Canada from 2013 to 2019.
Cache Valley virus (CVV) disease is a mosquito-borne zoonosis endemic to North America. CVV disease is reported most often in sheep, causing lethal congenital deformities. There are limited data on CVV in Ontario, which is the largest sheep producing province in Canada.

Feeding aspects related to treats specifically, remain underexplored. An e-survey was voluntarily completed by 716 dog caregivers predominantly from Canada and the USA to identify and describe caregivers' perceptions, motivations, and behaviours surrounding treats, and factors that influence decisions about feeding treats.

Objective: Black people are disproportionately targeted and disadvantaged in the criminal legal system. We tested whether Black exonerees are similarly disadvantaged by the stigma of wrongful conviction.
Hypotheses: In Experiment 1, we predicted that the stigma of wrongful conviction would be greater for Black than White exonerees.
Due to recent climatic and land use changes, Canada has experienced changes in tick populations, leading to an increased risk of tick bites and tick-borne pathogen exposure, especially in eastern Canada. Preventative recommendations for companion animals from veterinary professionals include regular use of tick prevention products and tick checks. Tick checks, specifically, should target regions of an animal's body which are deemed to be high risk for tick attachment.
