An open question in epidemiology is why transmission is often overdispersed, meaning that most new infections are driven by few infected individuals. For example, around 10% of COVID-19 cases cause 80% of new COVID-19 cases. This overdispersion in parasite transmission is likely driven by intrinsic heterogeneity among hosts, i.

Amidst growing international pressure for institutions that collect biological material to comply with the Nagoya Protocol, scientific gatekeepers such as herbaria, funding bodies, and academic journals increasingly request proof of Nagoya Protocol compliance. What happens when research is conducted in a country which does not have a comprehensive regulatory framework implementing the Nagoya Protocol? This article addresses this question through an examination of the difficulties that genetic resource collectors and biobankers may encounter in attempting to voluntarily comply with the Nagoya Protocol in Australia, a country that has not ratified the Nagoya Protocol at a federal level. It summarizes the requirements of the Nagoya Protocol, surveys the legal and regulatory situation that currently exists in Australia, and outlines the difficulties and ambiguities encountered by scientists and biobankers in attempting to navigate this system.
