A partial linkage map was constructed for the sweet cherry (Prunus avium L.) cultivar Emperor Francis from a population of 56 microspore-derived callus culture individuals. The callus cultures were genotyped for two allozymes and 90 random amplified polymorphic DNA (RAPD) markers using 79 random decanucleotide DNA primers and the polymerase chain reaction (PCR). Eighty-nine markers mapped to 10...

The fauna and zoogeography of the scorpions in the Aegean area are not well researched and based upon specimens randomly collected and described by various authors in the past 150 years. A first revision ot the scorpions in this region was provided by Kinzelbach in 1975 (completed with maps in 1985). However, the taxonomical validity of some species and most of the subspecies, first of all thos...

Myrmecologists have long studied the systematics, behavior, ecology, and evolution of ants. This first involved fundamental approaches including morphological description or behavioral observation, perhaps with the help of microscopes or marking ants with paint or wire. Many discoveries over the past 20 years have been accomplished with the help of more molecular approaches including allozymes,...

According to the lactadehydrogenase locus, genetic diversity of 9 samples Volga sevryuga different origin was studied. In total, 733 pieces young sevryuga, 99 producers and 107 were four-year-olds with MPERZ. To assess variability lactate dehyrogenase allozymes, method polyacrylamide gel electrophoresis used, as most appropriate for assessing influence environment in natural domesticated popula...

Alvinella pompejana lives on the top of chimneys at deep-sea hydrothermal vents of the East Pacific Rise. It is thought to be one of the most thermotolerant and eurythermal metazoans. Our experimental approach combines methods of population genetics and biochemistry, considering temperature as a potential selective factor. Phosphoglucomutase (Pgm-1 locus) is one of the most polymorphic loci of ...

Twenty-six D. pseudoobscura strains isogenic for xanthine dehydrogenase alleles from Mesa Verde, Colorado, were tested for differences in the biochemical properties of different allelic forms of xanthine dehydrogenase. No significant differences in binding affinity (Km) or substrate specificity of the enzyme were found. Significant variation among strains, in activity (Vmax) and among electromo...

The cactophilic Drosophila buzzatii (buzzatii complex ± repleta group, Ruiz & Wasserman, 1993) is native to South America and has attained a subcosmopolitan distribution by following passively its native host plants of the genus Opuntia. Studies in natural populations have shown that second chromosome polymorphic arrangements affect life history traits and morphometric traits associated with ®t...

-We examined patterns of variation in skeletal morphometrics (29 characters), allozymes (34 loci), mitochondrial DNA (mtDNA) restriction sites (n = 74) and fragments (n = 395), and mtDNA sequences (1,739 bp from cytochrome b, ND2, ND6, and the control region) among all species of Toxostoma. The phenetic pattern of variation in skeletal morphometrics generally matched traditional taxonomic group...

The phylogeographical patterns and population genetic structures of Varicorhinus barbatulus in Taiwan were investigated based on genetic diversity of 34 allozyme loci and nucleotide sequences of 3' end of the cytochrome b gene, tRNA genes, D-loop control region, and the 5' end of the 12S rRNA of mtDNA. Allozyme and mtDNA analyses revealing evident geographical structuring suggest limited gene f...
