2. MATERIALS AND METHODS
In this study, we only considered L. crocea in the mid-southern
ECS (120°E to 126°E,25°N to 29°N) that have available data over
long-term series. Also, we evaluated only overwintering distribution
patterns and overwintering habitat suitability because they are strongly
linked to the physiology fitness and survival rate during the juvenile
and adult stages and corresponding climatic migration phase of L.
crocea .
