| description |
Identification and characterization of seasonal
migration routes and stopover sites has been recognized
as important to the conservation of migratory species.
This project utilizes multiple regression models including
circular-linear regression to identify associations
between route choice, travel speed, and environmental
preferences using trajectory data of migratory Arctic
Terns (Sterna paradisaea) and environmental data
obtained through remote-sensing techniques. Results
of this study suggest that route choice on the southward
post-breeding migration route may be more dependent
on underlying environment than the northward postwintering
migration route. In contrast, travel speed
was variably associated with underlying environment
between southward and northward migrations, including
several differences regarding the impact of interactions
between environmental variables. These results reveal the
importance of using multiple metrics in the estimation
of spatial resistance and highlight conflicts between the
theoretical resistance framework of GIS and movement
analysis methods. |
