It's not me or Gail Morris who made the claim " O.e. rates were lower in the West recently." Project Monarch Health made those claims.
Another relevant discovery was made last fall - see message #3049 dated Jan. 28, 2011 to email@example.com
Namely, Gail Morris compared spore counts of WILD late summer and early fall Arizona fall migrants with WILD October fall migrants in Eagle Pass, Texas. And contrary to what Sonia Altizer has been saying for years; (i.e.
that western monarchs have much higher spore counts),
the AZ monarchs turned out to have slightly LOWER spore counts
than the TX monarchs!
Thus we see:
1) Arizona fall migrants still have low O.e. spore counts even after 10+ years of commercial butterfly releases in the West.
2) Spore counts of Arizona fall migrants have similar or slightly LOWER than spore counts than Texas fall migrants even though Arizona monarchs are considered western monarchs and Texas monarchs are considered eastern Monarchs.
