Öğe Histomorphometric and histochemical characteristics of the oesophagus of the greater mouse-eared Bat, Myotis myotis (Borkhausen, 1797)(Wiley, 2021) Paksuz, Emine Pinar; Paksuz, SerbulentThe aim of this study was to examine the histomorphometric and histochemical structure of oesophagus of the wild-caught greater mouse-eared bat M. myotis. For this purpose, 10 specimens of oesophagus were collected and processed. The oesophagus wall of M. myotis is composed of four layers: tunica mucosa, tunica submucosa, tunica muscularis and tunica adventitia. The mucosa is covered by a non-keratinized stratified squamous epithelium. There were no glands in the wall of the oesophagus. Tunica muscularis is composed of two muscle layers: internal circular muscular layer and an external longitudinal muscular layer Histochemical studies revealed that the oesophagus was AB/PAS and PAS positive indicating the presence of acidic and neutral mucosubstances. AB-PAS staining shows that glycoproteins were predominant in the all examined layers of the oesophagus. Because of the absence of oesophageal glands in M. myotis, positive reaction with AB-PAS staining may be due to secretion of salivary glands. Absence of oesophageal glands reflects the functional adaptation as high food passage rate for the insectivorous feeding habits of animals.Öğe New Distributional Records and Some Notes for Greater Noctule, Nyctalus lasiopterus (Mammalia: Chiroptera) from Turkey(Inst Zoology, Bas, 2011) Paksuz, Serbulent; Ozkan, BeytullahThe greater noctule, Nyctalus lasiopterus is one of the least known vespertilionid bats in Turkey, and more information is needed to evaluate its presence in Turkey. In this study, we report the species from Anatolia and the European part of Turkey. This is the first record from the European part of Turkey with an unusual roosting site. The recent records of N. lasiopterus from Turkey indicate that the species has a wide range in Turkey as a resident species, and its roosting habitats are represented by mainly mountainous and coniferous forests in Turkey.Öğe Protection of bats in caves opened for tourism: a reply to Furman, Coraman & Bilgin(Cambridge Univ Press, 2012) Paksuz, Serbulent; Ozkan, Beytullah[Abstract Not Available]Öğe The protection of the bat community in the Dupnisa Cave System, Turkey, following opening for tourism(Cambridge Univ Press, 2012) Paksuz, Serbulent; Ozkan, BeytullahThe aim of this study was to protect the bat community and roosting sites in the Dupnisa Cave System in the Yildiz (Istranca) Mountains in Thrace, the European part of Turkey, following the opening of the caves to tourism. We investigated the seasonal population dynamics and use of the cave system by bats, carrying out 15 surveys before (2002-2003) and 38 surveys after (2004-2008) the cave system was opened to tourism. We recorded 15 species of bats; the highest numbers recorded in a single survey were 54,600 hibernating and 11,000 breeding/nursing. Different parts of the cave system are used by bats to various degrees according to season. To protect the bats and the cave system the visitor schedule took into consideration the differences in seasonal use of the caves by bats. There was a significant increase in the total number of bats recorded in the cave system after opening for tourism, possibly because the gating of two entrances helped to control visitation. The results of our surveys of this cave system show that gating of entrances and visits by tourists are not necessarily incompatible with the use of caves by bats for both hibernating and nursing. Understanding how the three caves are used seasonally by the bat community, and for what purposes ( hibernation vs nursing), was critical for the establishment of an appropriate management plan for tourism.
