The Balkan long-eared bat ( Plecotus kolombatovici ) is a species of bat from the genus of long-eared bats ( Plecotus ) within the smooth-nosed family (Vespertilionidae). The scientific species name honors the Croatian zoologist Juraj Kolombatovic (1843-1908).
features
The Balkan long-eared bat is the smallest European species of long-eared bats and reaches a head-to-trunk length of 4.1 to 5.2 centimeters and a weight of six to ten grams. As with all long-eared species, the females are slightly larger than the males. As with the other species, the long ears, which reach a length of about 2.9 to 3.9 centimeters in this species, are striking. At the base, the ears touch. The tragus is relatively short with less than 15 millimeters in length, medium width and lance-shaped. The tail is relatively short at 41 to 52 millimeters and the last link is free. The thumb, thumb claw and feet are small.
distribution
The Balkan long-eared long-eared species is distributed in the Mediterranean and has three main distribution areas. The main distribution area extends from the Balkans of Croatia (on some Adriatic islands) via Greece ( Peloponnese ) to southwest Turkey , Cyprus , Syria to Lebanon and probably Israel and Jordan . It also occurs in the Cyrenaica in northeast Libya and from Morocco to northwest Libya. The species can also be found on Malta and Pantelleria .
The bat prefers summer-dry and coastal karst areas as well as river valleys and maquis . It occurs from sea level to higher regions of the Rif and Atlas Mountains in North Africa and in Parnassus in Greece (up to 1300 meters).
Way of life
There are only a few individual observations about the way of life of this species. Like all long-eared bats, it feeds almost exclusively on insects. They use small crevices and caves as well as rooms under rock arches and bridges as quarters. A nursery with around 90 females is known from an abandoned railway tunnel in the Peloponnese . Births take place after June.
Systematics
The Balkan long-eared long-eared species was described by Beatrica Ðulić in 1980 as a Croatian subspecies of the gray long-eared ear ( Plecotus austriacus ) with the scientific name Plecotus austriacus kolombatovici . Based on morphological and molecular biological investigations, the Balkan long-eared long-eared species was awarded.
However, some systematics combine them with the Canary Long-eared Long-eared ( Plecotus teneriffae ) and the North-West African Long-eared Long-eared ( Plecotus gaisleri ) to form a common species.
Threat and protection
The species is globally assessed by the International Union for Conservation of Nature and Natural Resources (IUCN) as "Least Concern" due to its comparatively large distribution area and population size. A decline in the population and a greater threat to the species are not known. Nationally and regionally, the species is under nature protection in most of its distribution area .
