Název v původním jazyce

Odours and sexual attraction - or hybridising potential in cryptic species

Popis výsledku v původním jazyce

The aim of this experimental study was 1) to compare the level of attraction in scent secretions and urine in cryptic bat species and 2) to analyse probability of mate selection in the same species with regard to pre-mating potential in inter-species hybridisation. Common Pipistrelle (Pipistrellus pipistrellus) and Soprano Pipistrelle (Pipistrellus pygmaeus) were used as model species. Odour attraction was tested using glass Y-shaped tubes in laboratory conditions. Secretions of scent glands and urine samples were collected from both sexes. Activity in tubes was recorded by an infrared video system and the obtained material was analysed in software Noldus Observer. The testing of the urine revealed that both sexes performed lower searching activity than in case of secretions of scent glands. In case of secretions of scent glands, so called auto-grooming was observed. This behaviour, especially in males, is related to odours spreading over the body.
