The C3H7O(+) ions of nominal structures 1, 2, 3, and 4, produced by protonation of acetone, propanal, propylene oxide, and oxetan, respectively, have been studied by a variety of collisional techniques. The nominal isomers 2 and 3 give, within experimental error, identical high-energy collision-induced dissociation (CID) mass spectra. In addition, the… (More)
We observed the mating behavior of the neck-banded snake Scaphiodontophis annulatus (a common species of colubrid in the South Pacific of Costa Rica) in the pre-montane wet forest of Las Cruces Biological Station (San Vito de Java, Costa Rica). Three S. annulatus were observed during courtship between 10-12 AM in a patch of primary forest. The two males… (More)
