red-handed tamarin

The red-handed tamarin is a small New World primate recognized for its distinctive reddish forelimbs and sociable groups; it has been studied by researchers affiliated with institutions such as Smithsonian Institution, University of Oxford, Max Planck Institute for Evolutionary Anthropology, University of São Paulo, and National Geographic Society. Fieldwork on the species has been conducted in regions administered by governments including Brazil, Peru, and Colombia, and reported in journals published by Nature Publishing Group, Elsevier, and Springer Nature. Conservation assessments have involved organizations such as the International Union for Conservation of Nature and collaborations with World Wildlife Fund, Conservation International, and local NGOs.

Taxonomy and naming

Taxonomically the red-handed tamarin is placed within the genus Saguinus, historically debated among primatologists at institutions like American Museum of Natural History and Royal Society panels, with nomenclatural acts reviewed by committees such as the International Commission on Zoological Nomenclature. Early descriptions referenced expeditions sponsored by entities like the Royal Geographical Society, and species concepts cited by researchers from University of Cambridge, Harvard University, and University of Zurich. Common and scientific naming conventions have been discussed at meetings of the International Primatological Society and in monographs from Cambridge University Press.

Description

Morphologically, the red-handed tamarin exhibits pelage and body proportions documented in field guides produced by Princeton University Press and illustrated in plates used by curators at Natural History Museum, London and Field Museum. Measurements reported by research groups at Yale University, University of California, Davis, and University College London detail weight, head-body length, and tail length comparable to other members of Callitrichidae, often contrasted with taxa described by authors affiliated with Columbia University, Duke University, and University of Michigan. Coloration patterns have been photographed during expeditions organized by Royal Botanic Gardens, Kew and published alongside work from Smithsonian Tropical Research Institute.

Distribution and habitat

The species’ range has been mapped in studies coordinated with environmental agencies such as Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis and Servicio Nacional Forestal y de Fauna Silvestre (Peru), and overlaps with ecoregions delineated by World Wildlife Fund and United Nations Environment Programme. Records originate from riverine forests near waters cataloged by projects from Amazonas (Brazilian state), Loreto Region, and Amazonas (Peru), and from protected areas managed by authorities like ICMBio and nations including Bolivia. Habitat descriptions reference vegetative surveys conducted by teams from Missouri Botanical Garden, Kew Gardens, and researchers at Universidad Nacional de la Amazonía Peruana.

Behavior and ecology

Social structure and behavioral ecology have been analyzed in comparative studies led by scholars at University of California, Santa Cruz, University of St Andrews, and University of Edinburgh, with ethograms developed in collaboration with the Max Planck Institute for Evolutionary Anthropology and field projects funded by National Science Foundation. Vocal communication has been compared to calls documented in archives maintained by Macaulay Library, and cooperative breeding and alloparental care were examined in papers from University of Zurich, Princeton University, and University of Pennsylvania. Predation and interspecific interactions have been observed in contexts involving species monitored by BirdLife International, Panthera, and researchers from Conservation International.

Diet and foraging

Dietary studies published in journals from Elsevier and Wiley-Blackwell report insectivory, frugivory, and exudativory, with foraging techniques recorded by teams at Smithsonian Tropical Research Institute, University of Cambridge, and University of São Paulo. Seasonal resource use was modeled using methods developed by researchers at Massachusetts Institute of Technology and ETH Zurich, and plant food items were identified with reference collections curated by Missouri Botanical Garden and Kew Gardens. Foraging behavior is often compared to sympatric primates documented by investigators from University of Oxford, Yale University, and University of Florida.

Reproduction and life cycle

Reproductive parameters, including mating systems and infant development, have been reported in longitudinal studies conducted by groups at University of Cambridge, Rutgers University, and University of California, Los Angeles, with demographic analyses using statistical approaches from University of Chicago and Columbia University. Life history traits have been contextualized alongside captive records from accredited facilities such as Association of Zoos and Aquariums institutions and research colonies associated with Max Planck Institute for Evolutionary Anthropology and Smithsonian National Zoo.

Conservation status and threats

Conservation evaluations have involved the International Union for Conservation of Nature Red List process and policy dialogues at Convention on Biological Diversity meetings, with threats identified by analysts at World Wildlife Fund, Global Environment Facility, and local ministries like Ministry of Environment (Brazil). Primary threats include habitat loss from projects financed or regulated by entities such as Brazilian Development Bank (BNDES), infrastructure initiatives reviewed by Inter-American Development Bank, and agricultural expansion guided by policies involving Ministry of Agriculture (Brazil), alongside pressure from illegal wildlife trade monitored by CITES and enforcement actions by agencies like IBAMA. Conservation measures recommended draw on frameworks from Conservation International, Wildlife Conservation Society, and community programs implemented with partners such as Fundação Amazonas Sustentável.
