The island
fauna has special characteristics that depend not
only on biotope diversity, but also on the island’s
geographical features: area, provenance, distance
from the mainland, and hydrodynamic processes. Black
Sea Biosphere Reserve includes islands located in
Tendrivska and Yagorlytska bays. The islands of
Babyn, Smalenyi, Potiyivski, Sybirski, and others
are located in Tendrivska Bay. The island of Tendrivska
Kosa (Tendra Island) separates Tendrivska Bay from
the Black sea. In Yagorlytska Bay, there are the
Malyi and Velykyi Kinskyi islands, Dovhyi and Kruhlyi
islands, and the Yehypetski Islands. The total area
of the islands of protected bays of the Black Sea
Biosphere Reserve is 3365 hectares, and the length
of the outer coastlines is 179.5 km. The following
biotopes were identified on the islands: reed thickets,
sandy and shell beaches on the sea coasts and coasts
of the deep-water parts of the bays; flooded solonchaks;
the inner parts of the islands with plant associations
that are typical for the coastal steppe and the
littoral-coastal complex. The mammal assemblage
of the islands includes 18 spe¬cies belonging to
6 orders, 10 families, and 16 genera. From 0 to
15 species of mammals live on individual islands.
The species composition of the mammal fauna depends
on the area of the island, available biotopes, the
possibility of animal exchange between the island
and the mainland. A number of islands have no other
inhabitants except birds during the nesting period,
primarily colonial ones. A number of islands belong
to the complex of reed thickets, in particular the
Yehypetski and Sybirski islands. These islands are
located along the mainland coast and are regularly
visited by wild boars and carnivorans; other islands
are littoral (Novi, Potiyivski), and there are no
permanent residents on them. Other islands are covered
only with reeds and have no permanent inhabitants.
On large islands, such as Dovhyi and Tendrivska
Kosa, there are 11–15 species of mammals (migrating
dolphins and bats not included), of which almost
20% are invasive and associated with human activity.
The species composition and state of populations
of micro- and mesomammals on the islands depend
on many factors, mainly catastrophic flooding, storms,
local epizootics, which can occur due to both natural
abiotic and anthropogenic factors. |
