Abstract:

We investigated the distribution and

abundance of the bats from the undergrounds in

Moldavia and Dobrogea. Data was collected

during 2002-2010. There were identified 20

species of bats (3-12 species/cave). In the

undergrounds from Moldova area the dominating

species are Myotis myotis/Myotis oxygnathus

(71,5%), and in Dobrogea, Myotis oxygnathus

(41,1%), Myotis daubentonii (24,1%), and

Miniopterus schreibersii (16,7%).

The most important underground shelter is

the Bats Cave from Rarău Mountains, which

hosts a wintering colony of 3500-3700

individuals of Myotis myotis/Myotis oxygnathus,

and in the warm season shelters 10 species of

bats. We analyzed the microclimate preferences

(for temperature and humidity), during

hibernation, at 15 species of bats. Nowadays,

from the undergrounds studied, only the Bats

Cave from Rarău has an adequate protection and

some populations of bats are seriously threatened

or have disappeared.
