Steller’s Jay that has been fitted with a radio-transmitter to track its movements and has been banded with a unique color combination, so it can be identified in the future without having to be re-captured.

Steller’s Jay and Marbled Murrelet management

Kristin Brunk is conducting research to determine if management of one bird species can conserve the other in California.

Map of habitat heterogeneity across the conterminous U.S., based on 30-m resolution standard deviation texture (21x21 moving window) of NDVI (index of vegetation greenness) from Landsat 8 imagery. Darker green areas indicate regions with higher habitat heterogeneity.

Mapping habitat heterogeneity using image texture

Laura Farwell is using image texture measures as powerful predictors of regional and global biodiversity patterns.
