Big Topic, Turned to October Headlines for Focus
Genetics of Disease? Avian Malaria? WNV?
Turns out, we dont need to worry..
Lynx Genetic Considerations
1) Mini review of lynx population genetic studies
2) Review of lynx hybridization studies
3) Needed genomic data

Stenseth et al. (1999) Suggest Climate Causes Large Scale Cycle Synchrony
The conservation of lynx populations is of greatest concern in the western mountains of the conterminous United States at the southern periphery of the species range. Recruitment is low in this region and many lynx populations.are geographically isolated.
- Koehler and Aubry 1994
Lynx Isolated
We let dispersal between patches be distance-dependent in an exponential fashion and fixed the fraction of migrants leaving each patch each generation. (p.1622 Ranta,Science)
