And now a bit of Cicada Data...from the National Science Foundation.
Announcer: Location, location, location. Geographer John Odland of Indiana University tells us the survival of cicada young may
depend on their mother's choice of the tree on which she lays her eggs.
Odland: Seventeen years is a long time in the life of a tree. Only a few generations of cicadas can use the same tree, so that evolution may select for those mothers who seek young trees that have a long life span that can nourish their young for the next 17 years. Those young trees are also most likely to be found along sunlit forest edges...
Announcer: ...edges, he says, humans often create...by building new housing subdivisions with patchworks of trees.
Chalk one up for suburban sprawl. That's Cicada Data. I'm Emilie de Azavedo.
