Probably the main refugia for these species [group (3)] were in the upper portions of Rock Creek, Washington Creek and possibly Deer Creek.   anvd [Please select]

Our observations suggest that certain species in group (3) dispersed rapidly from refugia in Rock Creek, Washington Creek, and possibly Deer Creek.   anvd [Please select]

In the savannas there are depressions, some of which contain water throughout the year; these are often surrounded by trees providing refugia for amphibians during the dry season.   anvd [Please select]

Some cool period forced the mainland populations of the two species into two refugia--peninsular Florida and eastern México--and the present area of intergradation is, therefore, of a secondary rather than a primary type.   anvd [Please select]
