DESCRIPTION

Study included analysis of the 7 morphological characters identified by Rea and Weaver (1990) "presents a picture of incomplete geographic subdivision" among "coastal" CACW, possibly affected by 122 of the 130 specimens evaluated having been collected by 1941, when a more intact landscape may have led to more genetic homogeneity in coastal-slope populations. "A modern-day set of specimens may show more complete morphological differentiation." Cytochrome b mtDNA sequencing indicates "population-level genetic differentiation" on the coastal slope, "likely due to genetic drift in small geographically isolated populations." The rapidity of landscape fragmentation and the wren's poor dispersal ability have contributed to genetic differentiation of several small, isolated populations. Results do not support recognition of C. b. sandiegensis but also do not support the decision of the USFWS not to list any coastal populations. Another study using a hypervariable locus is recommended.
