Some researchers suggest that arctiids are jamming the echolocation system of bats and others suggest that they are advertising their unpalatabilty. Using phylogenetic techniques we hope to determine which hypothesis is correct. Ultrasonic Communication in Tiger Moths. Once moths evolved ears and the ability to produce sound using tymbal organs, it was apparently a simple step to use these structures in their own courtship. Chemical Communication in Tiger Moths.
Arctiids are masters of chemical communication.
These compounds protect them from predators like bats and birds. In some cases males derive their sex pheromones from these defensive compounds. Molecular Biology of Protein Synthesis and DNA molecules as biotech reagents are the focus of Jim Curran's research. Molecular biology of protein synthesis. The ribosomal translation of the genetic code is a fundamental biological process.
