Another reason, and most likely the main reason for this research, is to provide information for other scientists. It is believed by our PIs that if reforestation is to occur, katydids and termites must be artificially reintroduced to the newly reforested area. The reason for this is that katydids provide a valuable food source for different types of birds, snakes, bats, monkeys, amphibians, ants, wasps, spiders and many other animals. Without katydids in the forest, many animals would starve to death. Termites would be needed because rainforest topsoil is extremely nutrient poor.
Termites help convert dead organic matter into usable nutrients.
You might wonder why anyone in the tropics would want to wear so much clothing. I found out the hard way our very first morning in the field. In other words, a type of invertebrate-specific pesticide is sprayed in a gaseous form up into the trees. Tarps are laid out to collect whatever falls. I was covered in these ants on our first morning fog.
