SCLEROPHYLL Fig. 14. Geographic variation in habitat preference in the long tailed flycatcher Bhipidura fvliginosa. This species, with essentially a peripheral range, occupies different habitats in various parts of the continent. This form of ecological variation indicates how, simultaneously with the develop- ment of genetic and morphological characters, isolates can become specialized for life in vegetation formations different from that occupied by the parental form. The numbers 1-9 on the map indicate races and isolates. The pairs of parallel lines represent distributional barriers (see Keast, 1958a). Note the isolate (9) in the mountains of central Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Harvard University.
