You might also want to check the herpetological literature (Jour.
Herpetology, Copeia, Herpetologica) over the past few years. These guys
are leagues ahead of the mammalogists with regard to the relationship
between speciation and karyotype, esp. with frogs and single-sex lizards.
Articles on this subject also periodically appear in Systematic Biology
and Evolution. There's also a discussion group - sci.bio.herp - on which
you can ask questions.
