Two new monkey species discovered

24.06.2002


Primates found in Brazil’s Amazon rain forest

Conservation International announced today the discovery of two new species of titi monkey in Brazil’s Amazon rain forest. The findings are published in a just-released special supplement to the journal Neotropical Primates.

They were described by Marc van Roosmalen, a primatologist at Brazil’s National Institute for Amazon Research (INPA), his son, Tomas van Roosmalen, and Russell Mittermeier, president of Conservation International and chair of the World Conservation Union (IUCN) Species Survival Commission’s Primate Specialist Group.



"Even though our closest living relatives, the primates, have been very well-studied for the past four decades, we are once again surprised by the discovery of even more species," said Mittermeier. "It proves how much we still need to learn about biological diversity, especially in the tropical rainforests."

One of the species, Callicebus bernhardi, or Prince Bernhard’s titi monkey, is remarkable for its dark orange sideburns, chest and the inner sides of its limbs, its reddish-brown back, and a white-tipped black tail. It lives between the east bank of the Rio Madeira and the lower reaches of its tributary, the Rio Aripuaña, south of the Amazon River.

Callicebus bernhardi is named for His Royal Highness Prince Bernhard of the Netherlands, a noted naturalist who created the Order of the Golden Ark to honor conservationists internationally. This prestigious award was bestowed upon co-authors Marc Van Roosmalen and Russell Mittermeier in recent years. Van Roosmalen will present the discovery to the Prince at Soestdijk Palace in Holland on June 25, four days before the Prince’s 91st birthday.

Prince Bernhard will also receive a special portrait of his monkey by Stephen Nash, CI’s technical illustrator, who has made major contributions to primate conservation worldwide through his posters and educational materials. The second new species, Callicebus stephennashi, is named after Nash, who works for Conservation International and is based at the Department of Anatomical Sciences at the State University of New York at Stony Brook.

Callicebus stephennashi, or Stephen Nash’s titi monkey, is silver in color, with a black forehead and red sideburns, chest and inner sides of limbs. Since fishermen brought it to Van Roosmalen’s Breeding Center for Endangered Wildlife in Manaus, it is uncertain where it lives. Van Roosmalen believes it came from the eastern bank of the Rio Purús in Central Amazonia.

"I am currently using my new discoveries to convince the Brazilian government to create nature reserves in the areas where I have found these species and where others, yet unknown to science, are likely to live," says Marc van Roosmalen. "The Amazon is extremely rich in biodiversity, and these newly-discovered creatures should be regarded as flagship species."

Scientists have described 24 monkeys new to science since 1990, according to Anthony Rylands, senior director at the Center for Applied Biodiversity Science at Conservation International, 13 of which are from Brazil. Including these two new monkeys, Brazil now has 95 species of primates, far more than any other country, and 134 species and subspecies, close to one-quarter of the global total. Van Roosmalen and Mittermeier have previously described four other new monkey species.

Titi monkeys are about the size of a small cat. They live in the dense understory of the South American tropical forests in small family groups of a mated pair and their offspring. Twenty-eight species, each with unique and colorful fur patterns, are now known to occur over a large part of the Amazon basin and the Atlantic forest of eastern Brazil.

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.

The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
