Detecting seasonal episodic-like spatiotemporal memory patterns using animal movement modelling

Spatial memory plays a role in the way animals perceive their environments, resulting in memory-informed movement patterns that are observable to ecologists. Developing mathematical techniques to understand how animals use memory in their environments allows for an increased understanding of...

Home range size estimates are often used to assess the amount of space required for animals to perform the activities essential for their survival and reproduction. However, in moving environments, traditional home range estimates may be ill suited to this task. In particular, traditional home...

Organisms are constantly making tradeoffs. These tradeoffs may be behavioural (e.g., whether to focus on foraging or predator avoidance) or physiological (e.g., whether to allocate energy to reproduction or growth). Similarly, wildlife and fisheries managers must make tradeoffs while striving for...

Animals must balance a series of costs and benefits while trying to maximize their fitness. For example, an individual may need to choose how much energy to allocate to reproduction versus growth, or how much time to spend on vigilance versus foraging. Their decisions depend on complex...

Background Animal movement modelling provides unique insight about how animals perceive their landscape and how this perception may influence space use. When coupled with data describing an animal’s environment, ecologists can fit statistical models to location data to describe how spatial memory...
