Discovering Climate-Animal Migration Relationships with New Tools

This study explores the connections between climate and animal migration using innovative methods for linking animal movement tracks, weather, and land surface data. The research investigates flight preferences of turkey vultures and golden eagles as well as wind support in water birds like albatrosses. The findings shed light on uplift mode preferences, wind optimization in migration path choice, and the impact of land use on migration patterns. Additional data analysis tools and support are utilized to enhance the study's insights.

  1. Discovering Relationships between Climate and Animal Migration with New Tools for Linking Animal Movement Tracks, Weather and Land Surface Data Gil Bohrer, Somayeh Dodge Department of Civil, Environmental & Geodetic EngineeringThe Ohio State University Martin Wikelski, Rolf Weinzierl Max Plank Institute for Ornithology Roland Kays North Carolina Museum of Natural Sciences David Brandes Lafayette College Steve Garrity Los Alamos National Laboratory Jiawei Han University of Illinois Urbana Champaign David Douglas USGS NASA Biological Response PI Meeting Seattle 4/2012

  2. Approach: Track annotation – linking environmental data to observed track points Albatross movement to Galapagos

  3. Showcase 1 - Flight preferences of Turkey Vultures and Golden Eagles Golden Eagles 2007-2009 • Key Questions: • Do Turkey Vultures and Golden Eagles have the same preference for wind conditions? • Do they actively target specific uplift modes? • Challenge • Partial overlap in space and time between Vulture and Eagle experimentslimits direct comparison Turkey Vultures 2005-2007

  4. Conclusions – Contrasting uplift-mode preferences

  5. Showcase 2 – Wind support in water birds Albatross feeding migration Galapagos - Peru click here to open 25M mp4 movie in separate window

  6. Optimization of wind support drives albatross path choice

  7. Not only albatrosses – Most water birds make smart use of offshore wind BrantaLeucopsis

  8. Showcase 3 - Landuse and timing of migration: Zebras NDVI and TRMM A ) m ( e d u t i t a L
