Lecture E1 (2024-10-17): Fundamentals of Movement and Navigation

In this lecture, we introduce key concepts in the study of animal movement related to movement during search and navigation. We start with a motivating examples from fiddler crabs -- homing and path integration as well as search (both for food and for displaced burrows). Ending those examples with search allowed us to discuss other more general search-related topics, such as kinesis, taxis, and triangulation. We then close coming back to path integration, but this time in Cataglyphis desert ants and their step-counting odometer. 

Before starting into movement and navigation in this lecture, we discuss the expectations for the final team project. 

Topic highlights:

  • path integration, homing behavior, and odometry
  • search movement strategies
    • random movement
    • directional movement
    • Lévy flights/walks
  • kinesis (stimulus triggered movement) and taxis (oriented movement)
  • triangulation

Important terms: navigation, homing, path integration, search, Lévy flight/walk, orientation, directional movements, random movements. odor-plume tracking, kinesis (plural kineses), klinokinesis, orthokinesis, taxis (plural taxes), klinotaxis, tropotaxis, telotaxis, anemo-, chemo-, geo-, magneto-, photo-, skoto-, triangulation, sequential triangulation, simultaneous triangulation, stereopsis, allothetic information, idiothetic information, odometer (and odometry)
