Nucleotide bias in SS/DS RNA viruses vs. retroviruses

Network was doing some odd things last night when I posted this, so 
apologies if this is a repeat posting....
 
I was wondering if any recent work has been done on SS or DS RNA virus 
phylogeny specifically mentioning nucleotide composition and 
nucleotide bias of RNAdepRNApol as an evolutionary influence.  I 
recently read the paper _Nucleotide composition as a driving force in the 
evolution of retroviruses_ (Bronson & Anderson (1994) J. Mol. Evol. 
38:506-532 article) which suggests mutational bias due to 
reverse transcriptase in retroviruses may play an important role 
in speciation.  I was curious as to whether these results may be 
generalized to other viral systems with similar low-fidelity nucleic 
acid replication, such as the SS and DS RNA viruses.  Any references 
or comments of use would be much appreciated (please Email). 
 
Thanks in advance
