Seed Eater Interactive Maps

Map
Input data

1) Click the map to position a tree!

2) Change the sliders below to adjust parameters that affect how far seeds might travel.

3) Hover over the contours to see what proportion of seeds travel that far, or use the ruler tool (top right) to measure exact distances.

4) Show additional plots of dispersal probability by clicking the 'Show plots' button on the right.

btle.york.ac.uk/SeedEater example spreadsheet

1) Select a sample dataset, or input your own by choosing user data.

2) You can double clicking rows in the Distance and Number of seeds columns to input data by hand.

3) You can also upload a csv file in the same format as the Seed Eater example spreadsheet . Data will be scaled using the quadrat size column to give values as seeds per square metre.

4) Look back at the plots on the Map tab to see how the cumulative probability of your data compares with the dispersal model. See btle.york.ac.uk/SeedEater for more information.
