Abstract
As the morphological determination of living individuals of the two sibling species S. araneus and S. coronatus is not possible, we have tested two biochemical methods to determine these shrews in ecological studies. After producing specific antibodies by rabbits, we performed an immunological test on 25 individuals. With this first method, a correct determination was achieved in 76% of the cases only. The second method proved very successful: a polyacrylamide gel electrophoresis showed a systematic difference for albumin (73 individuals analyzed). According to our experience, the necessary blood sampling (10-20 μl) seems harmless for the shrews
