Characterising menotactic behaviours in movement data using hidden Markov models
Ron R. Togunov, Andrew E. Derocher, Nicholas J. Lunn +1
1. Movement is the primary means by which animals obtain resources and avoid hazards. Most movement exhibits directional bias that is related to environmental features (taxis), suc…
Detecting seasonal episodic-like spatiotemporal memory patterns using animal movement modelling
Peter R. Thompson, Andrew E. Derocher, Mark A. Edwards +1
1. Spatial memory plays a role in the way animals perceive their environments, resulting in memory-informed movement patterns that are observable to ecologists. Developing mathemat…
State-space models' dirty little secrets: even simple linear Gaussian models can have estimation problems
Marie Auger-Méthé, Chris Field, Christoffer M. Albertsen +4
State-space models (SSMs) are increasingly used in ecology to model time-series such as animal movement paths and population dynamics. This type of hierarchical model is often stru…
Differentiating the Lévy walk from a composite correlated random walk
Marie Auger-Méthé, Andrew E. Derocher, Michael J. Plank +2
1. Understanding how to find targets with very limited information is a topic of interest in many disciplines. In ecology, such research has often focused on the development of two…
