TR10 - The story of a 17-year-old tamarin

On November 20th of 2014, the golden lion tamarin field team trapped a group of GLTs on the Rio Vermelho ranch in Brazil. One had the tattoo “TR10." Andreia Martins, the team coordinator, was astonished to find that this GLT, a female, was more than 17 years old!  Andreia’s carefully maintained database showed that TR10 had been born on the ranch on September 17, 1997. She was still in good physical condition but her teeth were worn to the gum line. Nonetheless, the observers saw her eating fruits and even insects, and her weight seemed normal. One member of her group was seen carrying two infants. The team could not determine if they had been born to TR10, although she certainly has had many infants over the years.

The discovery of such an old tamarin raises the question of their longevity. A wild GLT known as “GLT3” was trapped with her family and rescued from a patch of forest that was being cut down by its owner in 1983. GLT3 was one of the first tamarins to be trapped by Jim Dietz in his now-classic field study. She had been born in 1981. Jim relocated GLT3 and her family to the Poço das Antas Reserve, where she survived 10 mates and gave birth to 34 offspring before her death in November 1998, also at the age of 17.

According to Jennifer Mickelberg, who maintains the studbook for captive golden lion tamarins and studies the conservation genetics of wild tamarins, the median age of captive golden lion tamarins is between 7 and 8 years. About 10% of all captive female golden lion tamarins live to be 17. The record age is 31 (a captive male), and the oldest captive female lived to be 25. But mammals generally live longer in captivity than in the wild because they have a steady supply of nutritious food, good veterinary care, and no predators. It’s therefore really noteworthy that TR10 and GLT3 both made it to 17—and that Andreia’s team was able to document these results.

The detailed scientific records that have been kept by GLT scientists for more than three decades reveal some additional interesting details. TR10’s father, known as “T3”, had been born in the Stockholm Zoo in Sweden and had been reintroduced to the wild on the Rio Vermelho ranch in 1992. He had a rocky start in the wild, and had to be rescued several times after he was reintroduced. But he survived and paired up with TR10’s mother, “E6,”who had been born at the Emmen Zoo in the Netherlands and had also been reintroduced in 1992. T3 lived to be 9, but E6 lived to be at least 16 ½ years old. Perhaps longevity runs in families?

Remarkable longevity has a downside. Golden lion tamarins that live too long tend to fill the available breeding opportunities with their many offspring, which prevents unrelated tamarins from breeding.  The result can be an overall increase in inbreeding and loss of genetic diversity. Jim, Jennifer, and Andreia and her team will continue to monitor the tamarins and track their pedigrees. They’ll keep a special eye on TR10.

Buy Thirteen Gold Monkeys!

Thirteen Gold Monkeys, by Benjamin Beck, scientist emeritus in the Smithsonian Conservation Biology Institute and SGLT board member, is a novel based on the first years of the reintroduction of zoo-born golden lion tamarins to Brazil. It’s a story of hope, love, and unspeakable death in a disappearing Brazilian rainforest. A team of dogged conservationists tries to save this beautiful monkey species from certain extinction by reinforcing their numbers with tamarins born in zoos.

PRESS RELEASE: New Census of Wild GLT Population

OCT. 1 2014 - MEDIA RELEASE BY SAVE THE GOLDEN LION TAMARIN

A recent census of Brazil’s endangered golden lion tamarins provides new hope for the species’ future

A 2014 census of endangered golden lion tamarins conducted throughout the species’ current geographic range in Rio de Janeiro, Brazil, indicates that 3,200 individuals—double the previous estimate—live in four separate forest fragments. Experts in the biology of small populations agree that this number of these tiny primates, if living in a single block of forest, would be sufficient to save the species from extinction.

Centuries of deforestation and unplanned urban expansion in Brazil’s Atlantic Coastal Rainforest reduced the golden lion tamarin’s lowland forest habitat by 98%.  Remaining suitable forest was left in fragments, none large enough to support a viable tamarin population.  In the 1980s, when efforts to conserve these monkeys were initiated in Brazil, only a few hundred individuals were thought to exist in nature—all in a single watershed 60 miles northeast of the rapidly expanding city of Rio de Janeiro.

For over three decades, scientists working with Brazil’s Associação Mico-Leão-Dourado (AMLD; Golden Lion Tamarin Association) have been reintroducing zoo-born golden lion tamarins and translocating tamarins rescued from threatened forests.  AMLD also implemented long-term conservation education, sustainable agriculture and reforestation programs with local communities.  Over time, illegal capture of tamarins and deforestation dropped to nearly zero in the region. The number of tamarins estimated living in nature climbed slowly to 1,000 in 2000, and to 1,600 in 2005.  In 2003, the IUCN conservation status for the species was changed from “critically endangered” to “endangered”.

To conduct the 2014 census, AMLD scientists played prerecorded tamarin vocalizations to elicit responses from groups in forests throughout the species’ current geographic range, the São João River Basin, Rio de Janeiro state.  Results indicate that 3,200 golden lion tamarins live in four separate forest fragments.  This number of tamarins would be sufficient to save the species from extinction if the forest fragments are reconnected. AMLD is planting forest corridors on private lands to form these connections.

Dr. James Dietz, vice president of Save the Golden Lion Tamarin, a U.S. public charity created to support AMLD’s conservation work in Brazil said “I’m cautiously optimistic that AMLD will be able to reconnect just enough forest to keep golden lion tamarins from extinction for now.  Given the intense development in the region, protecting that reconnected forest for the long term will require constant monitoring and adaptive management. If we want golden lion tamarins to have a future, our challenge is to make sure that AMLD is always there to look after them.”

Seminar on Regulation of Agroforestry and Fallow Land Practices 

July 10, 2014.   More than 100 participants representing farmers, municipal governments, and state and federal environment agencies from throughout the state of Rio de Janeiro gathered at the II Seminar on Regulation of Agroforestry and Fallow Land Practices in Rio de Janeiro, organized by the Associação Mico-Leão-Dourado (AMLD) and the AS-PTA (Family Agriculture and Agroecology) at the União Biological Reserve.

With the objective of discussing state regulations for agroforestry practices (INEA Resolution 86) and the Rural Environmental Land Registry (Cadastro Ambiental Rural - CAR) created in Brazil’s new Forest Code, the seminar brought together farm families and government environmental agencies to reduce conflicts and strengthen environmentally sustainable agriculture in the state.  Farm families raised many questions to better understand what compliance will be required on their properties.

The CAR is a fundamental tool for the process of compliance with environmental regulations on rural properties.  It consists of a database of geo-referenced information for each property, including boundaries of Areas of Permanent Protection (APPs), Legal Reserve (RL), remaining native vegetation, area zoned rural, areas of social interest and areas of public use, with the objective of producing a digital map from which the values of the areas are calculated for an environmental diagnostic. 

The INEA Resolution Number 086 defines criteria and procedures for the development, management, and exploitation of agroforestry systems and for the practice of fallow lands in Rio de Janeiro state.  Several items of the resolution still need adjustments for landowners to be able to carry out the required bureaucratic processes and continue work on their properties .

The seminar participants enjoyed breakfast and lunch prepared from foods produced on agroforestry plots on family farms in the region. The seminar was organized by the AMLD Environmental Extension Program, coordinated by Nelsinho Barbosa, and received financial support from the Usina Terma Electica Norte Fluminense.
