TI  - Clinal variation and selection of MDH allozymes in honey bee populations.
PG  - 867-71
AB  - Latitudinal clines of malate dehydrogenase-1 (MDH-1) allozymes occur within honey 
      bee populations on three continents: Europe, North America and South America. The 
      North and South American populations are introduced and demonstrate that Mdh 
      allelic clines were established within the last 150 years. The frequency of the 
      'medium' electrophoretic allele increases in frequency with increasing latitude 
      while the 'fast' allele decreases with latitude on all the three continents. The 
      clines are best explained by the average daily high temperature for July on all 
      continents. These parallel clines provide evidence for selection on Mdh alleles 
      in honey bees.
