This possibility is supported by the fact that, among 21 specimens collected from the Kenai Peninsula region, and examined at the Museum of Vertebrate Zoology (MVZ), University of California, Berkeley, collectors or preparers labeled 18 specimens as intergrades between celata and lutescens (WMG).
Given that genetic studies suggest that hybridization and/or introgression between celata and lutescens could occur in south-central Alaska, and given that taxonomic determinations suggest integradation in specimens collected on the Kenai Peninsula, it would be of interest to know how putative intergrades from the Kenai Peninsula compare morphologically with samples from presumably pure populations of celata and lutescens.
We assumed that all samples from the Kenai Peninsula might be intergrades (although see discussion about fall migrants below), but we referred to them as "putative" because of the uncertainty of their taxonomic standing.
Shelley (2000) previously reported similar intergrades
from Garza Co.
Hirschfeld's sexual intergrades
fell between normal men and normal women--physically as well as psychologically.
However, 2:1-2:1:1 intergrades were significant components in both the Oku red soils (Okinawa Island) and the Pamagersari red soils (Java Island).
Intercalation of Al in the interlayer region of swelling 2:1 silicates leads to the blocking of the interlayers and the resultant formation of 2:1-2:1:1 intergrades similar in characteristics to Al-chlorite (Dixon and Jackson 1962; Carstea et al.
However, populations along a N-S axis tend to be morphological intergrades
between their nearest neighbor races.
undulatus erythrocheilus in turn clearly intergrades.
undulatus tristichus); (2) in 100% of females, abdominal semeions are absent or faint (vs at most 11%, most of which are probably intergrades); and (3) all except intergrades have distinct dorsolateral light lines (vs indistinct lines).
viridis, intergrades over a rather broad geographic area with the eastern subspecies, C.
viridis, and sexlineatus/viridis intergrades were taken from Trauth (1980).
