genus mouse pseudosyndrome It is one of the few terrestrial placental mammals to have established itself in Australia without human intervention.
of Native little mouse (Pseudomys delicaturus)The mouse, also known as the delicate mouse, was previously thought to be a single species that spread across a vast country, from the Pilbara in Western Australia, across parts of the Northern Territory, through Queensland to the New South Wales border. It was getting worse.
“We now know that there are actually three different species.” Dr. Emily Roycroftresearcher. Australian National University.
“Thanks to new genetic technology, we now identify not one but three species of these delicate mice.”
“Identifying undescribed species and giving them official names will go a long way in ensuring they are properly managed.”
“Although it may be difficult for amateurs to tell the species apart, this discovery is important for the future of this small mouse.”
“The two new species did not receive conservation or research attention because we did not know they were there.”
“For example, we don't know whether population declines were not detected as a result of all three species being assessed as a single unit.”
“This delicate rat was not a priority for conservation, but that's because the distribution of the rat was thought to be three times larger than it actually is. That would allow for a reassessment.”
“Sensitive mice differ from the mice you encounter in your home or backyard in several important ways.”
“Mus musculus, black rats and brown rats are non-native species that have been introduced to Australia since European colonization.”
“Evolutionarily and ecologically, they are very different from native rodents. They compete with our native species for resources.”
“Delicate mice are part of a group of native rodents that have evolved in Australia over the past five million years. They are an important part of Australia's natural environment and ecosystem.”
“The delicate mouse is Australia's smallest rodent. Weighing only 6 grams, it's really small.”
Researchers also discovered that the delicate mice were able to adapt well to their environment, whether it was an arid desert or a forest.
“These three species will now be referred to by common names that reflect their habitat: Western or Pilbara delicate mouse, Eastern delicate mouse and Northern delicate mouse,” they said. Stated.
The team's paper is journal molecular ecology.
