Changes in the plant population can effect changes in the animal population. However, since this is not my area of expertise, I searched Google under the key words "polyploidy finch" to get these possible sources:
http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/P/Polyploidy.html#Polyploidy_and_Speciation
http://www.biology-online.org/2/11_natural_selection.htm
http://redpath-museum.mcgill.ca/Qbp/2.About%20Biodiversity/processes.htm
http://books.google.com/books?id=khEUYMtmuOQC&pg=PA332&lpg=PA332&dq=polyploidy+finch&source=bl&ots=Km4vZ7PbQq&sig=rPHa7LOfrevTGMyumo5etuRwf2I&hl=en&sa=X&oi=book_result&resnum=3&ct=result
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
I hope this helps. Thanks for asking.
