Effect Of Maternal Age On Offspring Social Behaviour In Drosophila Melanogaster, Shirley Long
Effect Of Maternal Age On Offspring Social Behaviour In Drosophila Melanogaster, Shirley Long
2016 Undergraduate Awards
Aging can be defined as the natural and progressive decline in physiological functioning leading to increased risk for disease and death. Although the effects of age are well characterised, much less work has been done to study whether these detrimental changes can be transmitted to offspring. Advanced parental age has been correlated with higher incidence of neuropsychiatric disorders such as autism in children. As average maternal age increases in North America, it is becoming increasingly relevant to study the effects of maternal and paternal age on offspring social behaviour. We hypothesize that advanced maternal age in Drosophila melanogaster will affect …

Aged dogs exhibit a spectrum of cognitive abilities including a syndrome similar to Alzheimer's disease. A major impediment to research so far has been the lack of a quick and accurate test of visuospatial memory appropriate for community-based animals. We therefore report on the development and validation of the Canine Sand Maze. A 4.5-m-diameter circular pool was filled with a sand and powdered food reward mix to a depth of 10 cm. Dogs were given 4 habituation and 16 learning trials which alternated a food reward being half (control trials) or fully-buried (acquisition trials) in a fixed location. After a …
