title: Amounts of nuclear DNA in anurans of the USSR.
abstract: The amounts of nuclear DNA in blood erythrocytes of 18 species of Anura from the USSR have been determined to be in the range of 4.0--20.6 pg (10(-12) g). Brown frogs of genus Rana have lower mean genome sizes than green frogs. Palaearctic Anura, as a whole, have a greater content of nuclear DNA than the species of the same families from regions further south.
