  2. Chiroptera Chiroptera accounts for almost one-quarter of existing mammalian diversity Kingdom: AnimaliaPhylum: ChordataClass: MammaliaOrder: Chiroptera Rodentia Megabats : Old world fruit bats Microbats : insect bats Chiroptera Wilson, D. E. and D. M. Reeder, 2005

  3. Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Chiroptera Family: Rhinolophidae Genus: Rhinolophus emuseap.nmns.edu.tw Shiang- Fan Chen Formosan Lesser Horseshoe Bat Rhinolophus monoceros Formosan Woolly Horseshoe BatRhinolophus formosae Microbats Horseshoe-shaped nose leaf used for directing ultrasound Broad, rounded wings, with fluttery flight patterns Only found in Taiwan

  4. Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Chiroptera Family: Vespertilionidae Genus: Pipistrellus Wikipedia Japanese House Bat Pipistrellus abramus Microbat Found in towns and villages Roosts under ceilings or under the roof of buildings Found in East Asia: China, Taiwan, Korea, and Japan

  5. Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Chiroptera Family: Pteropodidae Genus: Rousettus Rei Segalii Egyptian Fruit Bat Rousettus aegyptiacus Megabat Old World Fruit Bat Echolocation Excellent Sense of Smell Found in most of Africa and the Middle East

  7. Are Chiroptera Monophyletic? Chiroptera Are Monophyletic Traditionally Chiroptera has been thought of as monophyletic (Gregory et al., 1910) Based on complete sequence of mitochondrial DNA (Nikaido et al., 2000) Distinctive cranial and cervical innervation of wing muscles (Thewissen and Babcock, 1991) Chiroptera Are Not Monophyletic Based on Analysis of patterns of connections between the retina and midbrain megabats were suggested to be more closely related to primates than microbats. (Pettigrew, 1986)

  8. (Wible and Novacek) (Pettigrew et al.)

  9. Methods Maximum parsimony (MP)Minimum evolution (ME) Bayesian analysesMonte Carlo Simulations (parametric bootstrapping)Character Mapping (195 morphological characters)

  10. Questions Are microbats more related to primates or megabats? Since the megabat Rousettus aegyptiacus (Egyptian Fruit Bat) uses echolocation like microbats, is it a good species to study for phylogenic relationships? More investigations of the clade arrangement of Mammalia are warranted.

  11. Thank You
