[FLEAS (SIPHONAPTERA) OF MAMMALS AND BIRDS IN THE CISCAUCASIA]

Area of Science:

• Zoology
• Ecology
• Parasitology

Background:

• The Ciscaucasia region's flea fauna composition is incompletely understood.
• Fleas (Siphonaptera) are significant ectoparasites with complex host-parasite relationships.

Purpose of the Study:

• To document the flea species diversity and distribution in Ciscaucasia.
• To identify host associations and biogeographical patterns of fleas in the region.

Main Methods:

• Faunistic survey of fleas across Ciscaucasia.
• Identification of flea species and their mammalian and avian hosts.
• Analysis of species distribution and endemism.

Main Results:

• A total of 76 flea species were identified in Ciscaucasia.
• Mammal-associated fleas, particularly on rodents, were most abundant.
• Thirteen species were associated with birds from various orders; two subendemic species were found.
• Thirty-three species exhibited widespread distribution, while others were restricted to specific natural areas.

Conclusions:

• The flea fauna of Ciscaucasia is diverse, with a strong association with mammal hosts.
• Understanding flea distribution is crucial for ecological and epidemiological studies in the region.
• Limited endemism suggests significant gene flow or recent colonization events.
