Chiave di determinazione dei Chirotteri (Mammalia) della Svizzera attraverso l'osservazione al microscopio ottico della struttura dei peli

Abstract

Ident\\`\\if\\`\\icat\\`\\ionkey of bats (Ch\\`\\iroptera) from Sw\\`\\itzerland based on hair structnre observed through opt\\`\\ical m\\`\\icroscope, - The identif\\`\\ication of mammalian hairs by microscope remains an efficient and well-known technique, but only a few studies concern bats. We studied hair morphology of the 29 species listed from Switzerland and present a dichotornic identi- f\\`\\ication key based on overhair rnorphology observed by using optical microscopes. This key allows to identify most of the genera and also some typical species. The final purpose of this key is to give the possibility to analyse and to identify quickly the hairs found in guano, taken from their bat roosts.
