Koalas, the ever-adorable symbol of Australia, have fallen prey to habitat degradation and disease in recent years. To shore up remaining populations, researchers from San Diego Zoo Global have teamed with Australian scientiststo study these fuzzy animals to better understand koala mating strategies, habitat use, and movement patterns. Technology has revealed the importance of male bellow calls and scent gland development and how they relate to mating success. The team is also playing a leading role in securing legal protection for koalas, which is essential for sustaining remaining populations.
