Quick Quiz Questions
Vila et al.2003. Rescue of a severely bottlenecked wolf (Canis
lupus) population by a single immigrant. Proc. R. Soc. Lond. B 270:91-97.
- Even though we expect a loss of
genetic diversity in small populations and predict that immigration will
relieve inbreeding depression, why is there so little empirical evidence
that supports this hypothesis? Why
was it possible to obtain this information to fill this gap in our
knowledge in this study system?
- What would Figure 1 have looked
like if there had not been immigration?
Why? Redraw Fig.1 a and b to illustrate your point.
- What evidence is presented to
support the hypothesis that there was close inbreeding after the extinct
population was refounded by a single female?
- What value was there of having
different kinds of molecular markers in this study?
- How does your opinion about the
value of genetic mixing in this study compare to your opinion about the
value of genetic mixing in the endangered Goodeid fish?
