SLIDE 2

 What are the general mechanisms that control large‐

scale patterns of self‐organization in large mammals?

SLIDE 3

 What is the ecological function of observed aggregations?

SLIDE 4

 Can we predict how environmental change will affect

self‐organization of aggregating organisms?

SLIDE 5

 Migrating wildebeest herds in the Greater Serengeti Ecosystem

SLIDE 6

 Use historical satellite imagery to identify landscape‐

level patterns of aggregation in wildebeest herds

SLIDE 7

 Manually georeference individuals

SLIDE 8

 Classify landscape variables from satellite imagery and

existing databases

SLIDE 9

 Analyze geometries and distributions in relation to

landscape features

 Risk from anthropogenic and predator sources  Distribution of high quality food resources  Distribution of water resources

SLIDE 10

 Standardize data collection by commissioning current

satellite imagery of wildebeest herds

 Develop citizen‐science based platform for manual

classification of individuals

 Consider questions of scale  Build predictive models to determine how

environmental change will affect self‐organization patterns of wildebeest
