Isolation by distance in Middle Dalmatia—Yugoslavia

Abstract

Parameters of Malécot's isolation-by-distance model are estimated for biological (anthropometric head and body dimensions, morphometric dimensions of metacarpal bones, quantitative and qualitative dermatoglyphic traits, and physiological/cardiorespiratory/variables) and linguistic distances and migrational kinship on the island of Korcula and the Peljesac peninsula in Middle Dalmatia, Croatia, Yugoslavia. Resulting parameters and the fit of the model are compared, for both regions, as well as with results of similar analysis in other parts of the world. The fit of the model is highly significant for migrational kinship and linguistic distances and less so for biological traits. Differences between these two populations, which live under basically similar ecological conditions, are explained by variation in biological and sociocultural history.

Estimating Human Inbreeding Coefficients: Comparison of Genealogical and Marker Heterozygosity Approaches

“…Their ethnic history, demography, population biology and genetic structure have been investigated for more than 50 years (Bennett et al 1983;Rudan et al 1987;Waddle et al 1998;Tolk et al 2001;Barać et al 2003). The chosen islands are known for their reproductive isolation and consanguinity.…”

Estimation of inbreeding, kinship, genetic distances, and population structure from surnames: The island of Hvar, Croatia

“…Such a finding was expected, since the analyzed period of marital migrations postdates the establishment of surnames on the island (Rudan et al, 1987b). However, the correlation of migrational kinship and kinship determined from surnames was the greatest for the migrational period 1850-1891; subsequently, it rapidly decreased.…”

“…A detailed description of the ethnohistory of the island and region has already been reported (Rudan, 1972(Rudan, , 1975Rudan et al, 1982aRudan et al, ,b, 1987bRudan et al, , 1990Rudan et al, , 1992Rudan et al, , 1994Sujoldžić, 1982;Š imić and Rudan, 1990;Martinović et al, 1995;and Marković, 1996). Some of the most important facts with a major impact on a formation of population structure are briefly reviewed subsequently.…”

“…The basic hypotheses include the following: (a) Due to extreme reproductive isolation of the island population that lasted for centuries as a result of various geographic, sociocultural, political, and economic reasons (Rudan et al, 1987b), very high values of total inbreeding and kinship are expected; (b) Correlation between a genetic distance matrix based on surname analysis and the corresponding matrix based on erythrocyte antigen analysis (on the same sample of examinees) is expected to be significant; (c) The correlation between a kinship matrix based on surname analysis and the corresponding matrix based on marital migration analysis is expected to be of a lesser significance, since the analyzed period of marital migrations long postdates the establishment of surnames on the island (Rudan et al, 1987b); (d) Finally, there is no theoretical ground to expect significant correlations between interpopulational distances based on isonymy and other distance measures primarily biological and sociocultural (with a possible exception of linguistic distances, preserved along with surnames of newcomers to the island).…”

Genetics, ethnohistory, and linguistics of Brač, Yugoslavia

“…Anhysiology were significant at the 5% level; Rowever, the other nine biological data sets peninsu f a and the endogamy estimate have occurred overt K e past few centuries for Peljesac ma R es it less likely that genetic a highly significant fit o P the model for mithropometry (body varia r les) and male failed to demonstrate an adequate correspondence between Malecot's model and empirically generated biological data (Rudan et al, 198713). In addition, the migrationderived value of Malecot's "a" parameter (0.0012) is among the lowest recorded in continental Europe.…”
