We dedicate this work to the memory of our
colleague, friend, and co-author, Hermes
W. Mianzan, who passed away during the
final editorial steps. Hermes was an
insightful researcher, and an enthusiastic
teacher of the ecology of fronts. Endowed
with a perennial sense of humor, he once
told his students that “… the only important
things are fronts. The rest is just water for
fishes to travel from one front to another.”
