The formal descriptions of the seven species, all of which are members of the genus Apomys, were published on 20 May in Fieldiana, the peer-reviewed journal of The Field Museum, where the project is based. The nine co-authors included biologists from the University of the Philippines, the Philippine National Museum, Conservation International-Philippines, Utah Museum of Natural History, and Florida State University.
"These animals are part of the rich biological heritage of the Philippines", said Dr. Theresa Mundita Lim, Director of the Protected Areas and Wildlife Bureau, Department of the Environment and Natural Resources (DENR). "The forests where they live are crucial watershed areas for Manila and many other cities. Protecting their mountain forest habitat is good for them and for people." The DENR is a collaborator of the project, providing assistance at field sites and co-organizing conferences on wildlife and conservation.
All of the species are forest mice, and each species lives only in a small part of Luzon. According to Dr. Lawrence Heaney from The Field Museum, project leader and lead author of the publication, "These are wonderful little mice that live in forested regions high in the mountains. Although they are often abundant, they actively avoid humans and rarely cause any harm. They prefer to eat earthworms and seeds on the forest floor."
Two of the new species live only in the Zambales Mountains (on Mt. Tapulao), two live only on Mt. Banahaw (south of Manila), two only in the Mingan Mountains of Aurora Province, and one lives only in the Sierra Madre of northeastern Luzon.
"It is extraordinary that so many new species of mammals remain to be discovered in the Philippines," according to Danilo Balete, leader of the project's field team. "In the past 10 years we've published formal descriptions of 10 other species, and other biologists have described five more. And we are nowhere close to the end of our discoveries. The Philippines may have the greatest concentration of unique species of animals of any country in the world."
Dr. Scott Steppan, co-author and head of the laboratory at Florida State University where the DNA portion of the study was conducted, said, "The Philippines is an ideal place to study the evolution of animal diversity, even better than the famous Galapagos Islands. These animals have been evolving in the Philippine archipelago for millions of years."
Mr. Romeo Trono, Country Executive Director for Conservation International - Philippines, said, "Protecting land and marine resources is key to maintaining healthy ecosystems which deliver ecosystem services such as food, clean water, health, tourism and cultural benefits and stable climate which are vital to the very survival of every Filipino. Although small in size, these little animals are part of our biodiversity which forms the basic foundation of healthy ecosystems."
M. Josefa Veluz, biologist at the Philippine National Museum and co-author of the study, pointed out that the new species from the Sierra Madre and Mt. Banahaw live within protected areas, but those from the Mingan Mountains and Zambales do not. Logging, expansion of agriculture, and mining all have an impact on wildlife and watersheds, she said.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
