Presentation at the North American Society for Bat Research Meetings 2014, Albany, NY.

1. Integrating Population Genetic
and Quantitative Genetic Models
Reveals Selection in Echolocation
Liliana M. Dávalos, Jon Flanders, Winston C.
Lancaster, Bonnie Lei, and Amy L. Russell

2. Pteronotus parnellii
CF echolocation with Doppler shift compensation in the
New World

3. Why divergence? (in allopatry)
• Null hypothesis
• Genetic drift (e.g., Puechmaille et al.
2011)
• Selection
• Habitat physical features
• Clutter (e.g., Odendaal et al. 2014)
• Humidity (e.g., Guillén et al. 2000)
• Morphology
• Acoustic environment (e.g., Gillam &
McCracken 2007)
• Other species (Kingston et al. 2001*)
• Prey (Kingston & Rossiter 2004*)

5. Lande 1976 Evolution
• Little difference in means
• High variance can
accommodate wide
variation

6. Where could
we find such
estimates?
In the genetics data
Hey & Nielsen 2007 PNAS

8. “ancestral” data, Clare et al. 2013 BMC Evol Biol

9. What other data do we have?
• Habitat physical
features
• Clutter (e.g.,
Odendaal et al.
2014)
• Humidity (e.g.,
Guillén et al. 2000)

12. Armstrong & Kerry 2011 J Theor Biol

15. What is left?
• Null hypothesis
• Genetic drift (e.g., Puechmaille et al.
2011)
• Selection
• Habitat physical features
• Clutter (e.g., Odendaal et al. 2014)
• Humidity (e.g., Guillén et al. 2000)
• Morphology
• Acoustic environment (e.g., Gillam &
McCracken 2007)
• Other species (Kingston et al. 2001*)
• Prey (Kingston & Rossiter 2004*)
