Australia’s frogs are having trouble finding love. Traffic noise and other sounds of city life, such as air conditioners and construction noise, are drowning out the mating calls of male frogs in urban areas, leading to a sharp drop in frog populations. But, in the first study of its kind, Parris, a scientist at the University of Melbourne has found that some frogs have figured out a way to compensate for human interference in their love lives.

perhaps, locate myself. I teach and write about a loose and baggy territory
called Las Americas, the Americas, and most often about the part of that

course, but the demarcation is far more flexible because of its plural referent.
The writers who inhabit this territory possess dual citizenship, for they are
self-avowed "Latin American" writers at the same time that they are also
