Growth and size of Triturus vulgaris and T. cristatus (Amphibia) in different parts of Norway
The growth and size of the newts, Triturus vulgaris (L.) and T. cristatus (Laurenti) in different parts of Norway (+ Jämtland, Sweden) were studied. Age was estimated from skeletal growth marks, size‐frequency histograms and, for the males, from the number of testis lobes. On average, the T. vulgari...
