A revision
of species composition of the genus Sylvaemus in
the territory of Mykolaiv Oblast (Ukraine) was carried
out. The occurrence of three species was conformed:
S. sylvaticus, S. tauricus, and S. uralensis. The
species S. arianus was not found in the Kinburn
Peninsula. Morphological features, aspects of ecology
and biology of the species are given. Sylvaemus
sylvaticus dominates in woods and shrubs, S. uralensis prevails in open habitats, and S. tauricus is a
non-abundant species occurring only in the forest-steppe
zone. The breeding season has only one peak in July.
The dependence of the main morphometric features
from the age was examined. The most important features
for species diagnostics the length of foot (Pl)
and ear (Au). Tail length (Ca) has the lowest diagnostic
value. |
