The smallest native mouse of Australia – scientifically known as Pseudomys delicatulus, is a rodent belonging to the Muridae family, measuring between 5-7cm in length and weighing approximately 6 grams. It was previously believed to be a single species scattered throughout this Oceania nation.
However, by utilizing new genetic technology, researchers discovered three distinct rodent species. They have been named after the locations where they were found.
Dr. Emily Roycroft, the lead author of the study, stated that this discovery is significant for the research and conservation efforts of Pseudomys delicatulus, as scientists were previously unaware of their existence.
The research indicates that Pseudomys delicatulus mice have adapted well to environments ranging from arid deserts to dense forests.
Dr. Roycroft noted that this native rodent species has evolved in Australia for 5 million years but must compete with invasive species such as house mice, black rats, and brown rats for survival.
