Preserved
and protected within the territory of the Kamyanska
Sich National Nature Park areas of psammophytic
steppe are natural habitats of the highly specialized
and stenotopic northern mole vole Ellobius talpinus.
Studies of recent settlements of the species have
revealed their strong preference for slopes of riparian
balkas and upper terraces of the Kamiansko-Mylivska
section of the Kakhovka Reservoir covered with psammophytic
vegetation. As places for colonies, these rodents
definitely prefer dry loess-sandy soils of light
composition, avoiding shrubbery and dense grass
due to the danger of disguising in them flying and
terrestrial predators. A total of 14 "living"
colonies of the northern mole vole were registered,
9 of which were defined as small-family settlements
(less than 100 m2). The other five colonies had
a clearly multi-family structure and a large area
(680–1720 m2), within which spatially isolated clusters
of emissions were traced hypothetically perceived
as separate family constructions (up to 270 m2).
According to these landmarks, some large settlements
contained 3 to 9 networks of family burrows located
at a distance of 57 to 106 m. Five small uninhabited
settlements (45–70 m2) were also recorded with signs
of last year emissions. These settlements were located
on the periphery of large colonies, 108–219 m far
from the nearest emissions of "living"
settlements. Estimates of the total number of inhabitants
of the 14 "living" settlements in the
territory of the Kamianska Sich National Nature
Park range from 50 to 200 individuals. As of July
2021, the number of reproductive adults in the registered
colonies of the species is 40–50, while the number
of young of the current year of birth should be
estimated at least 100–120 individuals. Colonies
of the northern mole vole are characterized by the
presence in their vicinities of spring ephemeroids
such as T. hypanica, T. schrenkii, B. versicolor,
and C. reticulatus, which are indicator species
of primary virgin steppe biotopes. The results of
surveys of northern mole vole colonies and ecological
assessments of protected natural habitats of the
Kamianska Sich National Nature Park provide grounds
for a favourable prognosis of further preservation
of the last range segment of the species in the
territory of Right-Bank Ukraine. |
