DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Dynamics/7/"
 >Collective Behavior in Locust Swarms from Differential Equations to Data<
 /a>\nby Jasper Weinburd (Harvey Mudd College) as part of Little school dyn
 amics\n\n\nAbstract\nLocusts are devastating pests that infest and destroy
  crops. Locusts forage and migrate in\nlarge swarms which exhibit distinct
 ive shapes that improve efficiency on the group level\, a\nphenomenon know
 n as collective behavior. One of the difficulties in understanding and pre
 venting\nthese collective behaviors has been a lack of biological data for
  individual interactions between\nlocusts. In this talk\, I’ll first des
 cribe mathematical models for these phenomena on both the\ncollective and 
 individual levels. I’ll then discuss a collaboration with undergraduate 
 students that\nuse field data derived from video footage of locust swarms.
  We digitized nearly 20\,000 locust\ntrajectories and revealed individual 
 behaviors that depend on a locust’s motion and the relative\nposition of
  its nearby neighbors. Finally\, I will illustrate the challenges and pote
 ntial benefits of\nincorporating these field observations into our models 
 of locust swarms.\n
