Australian researchers have made a groundbreaking discovery, identifying two new species of native rodents in the country. The study, published on Thursday, was conducted by a team from the Australian National University (ANU) and the Commonwealth Scientific and Industrial Research Organization (CSIRO).
Using advanced genetic technology, the team revealed that what was once considered a single species of the delicate mouse actually comprises three distinct species. The newly identified species have been named the western delicate mouse, eastern delicate mouse, and northern delicate mouse, each reflecting their specific geographic regions.
Emily Roycroft, the lead author of the study from ANU, highlighted the significance of this discovery for conservation and research efforts. \"The two new species haven't had any conservation or research attention, because we didn't know they were there,\" Roycroft explained in a media release. \"We don't know, for example, if population declines have gone undetected as a result of all three species being assessed as a single unit.\"
The study also found that delicate mice have excellently adapted to a variety of environments, ranging from arid deserts to lush forests. These native rodents have been evolving in Australia for approximately five million years. However, they face competition from introduced invasive species such as house mice, black rats, and brown rats, which vie for the same resources.
This discovery not only enhances our understanding of Australia's rich biodiversity but also underscores the importance of genetic research in uncovering hidden species that play crucial roles in their ecosystems.
