The Conservation Status of Callicebus caquetensis (Pitheciidae): A New Species in Southern Caquetá Department, Colombia

  title={The Conservation Status of Callicebus caquetensis (Pitheciidae): A New Species in Southern Caquet{\'a} Department, Colombia},
  author={Javier Garc{\'i}a and Thomas R. Defler and Marta Luc{\'i}a Bueno},
Abstract Moynihan (1976) mentioned an undescribed species of Callicebus between the ríos Caquetá and Orteguaza, Caquetá Department, Colombia. In August 2008, we confirmed the new species, which is phylogenetically related to C. ornatus and C. discolor to the north and south of the type locality respectively. We described this species as Callicebus caquetensis Defler et al., 2010 establishing its distribution through direct observations and information from local communities. Eighty-two animals…

Increased data on the responses of pitheciid species to forest loss and fragmentation are necessary in order to address pitheciaid conservation, especially in areas undergoing severe habitat loss.

Plecturocebus caquetensis (Primates: Pitheciidae)

Abstract: Plecturocebus caquetensis (Defler, Bueno, and García, 2010) is a Neotropical primate commonly called the Caquetá titi monkey. It is small-sized with long, soft pelage of mixed coloration

Trends in the use of studbooks in captive breeding programs of neotropical primates

A search of studbook reports revealed a discrepancy between regions where in situ conservation and ex situ conservation actions have been made, which underscores the need for international cooperation to strengthen conservation efforts, build infrastructure, increase effective population sizes and ultimately establish viable populations.


A history of some details the author's research in eastern Colombia is presented for the last 27 years since 1977 in Vichada, Vaupes, Amazonas and most recently in Meta up to the present. Some

Pitheciid research comes of age: Past puzzles, current progress, and future priorities

New directions and priorities for future research are proposed to ensure the effective conservation of pitheciids, and it is demonstrated how studies of this family are now the focus of hypothesis‐driven research that will allow its biology to be compared with other primate lineages.

wild animals in Villavicencio, Colombia. Estudo retrospectivo dos achados histopatológicos em animais silvestres de vida livre e cativeiro em Villavicencio, Colômbia

Un primer estudio retrospectivo sobre los hallazgos histopatologicos observados en animales silvestres atendidos en el Laboratorio de Histopatologia de la Escuela de Medicina Veterinaria de the Universidad de los Lla -nos, Villavicencio (Colombia, entre 2004 y 2011).

A retrospective study of pathological findings in wild and captive-wild animals in Villavicencio, Colombia

A first retrospective study of histopathological findings in wild animals samples received at the Histopathology Laboratory of the School of Veterinary Medicine, University of the Llanos, Villavicencio (Colombia), between 2004 and 2011 found that gastrointestinal disorders were the most common pathological findings.

The low genetic variability of the Central American howlers suggests a resistance to inbreeding depression potentially experienced during population bottlenecks, and the pattern of bisexual dispersal facilitates colonization of regenerating habitats, and in suitable, protected habitats they have shown the capacity for strong population recovery.

Callicebus caquetensis: A New and Critically Endangered Titi Monkey from Southern Caquetá, Colombia

A new species of titi monkey callicebus from the Department of Caquetá, Colombia, that belongs to the Callicebus cupreus group and should be classified as Critically Endangered (CR) due to the severe fragmentation of its habitat and very small population.

New data on the ecology and geographic distribution of Saguinus inustus Schwarz, 1951 (Primates, Callitrichidae).

The study has confirmed the presence of the Species in the Amanã area, carrying out the first records of the species in flooded forest habitats, and collection of specimens during a survey of mammal diversity in the ASDR.

Notes on the Ecology of Buffy Saki Monkeys ( Pithecia albicans , Gray 1860 ) : A Canopy Seed-Predator

Data on the ecology and diet of buffy sakis (Pithecia albicans) were obtained during a 20-month study in an entirely undisturbed terra firme forest in the upper Urucu river, Amazonas, Brazil. Groups

Population status and identification of potential habitats for the conservation of the Endangered black howler monkey Alouatta pigra in northern Chiapas, Mexico

Abstract In the Mexican state of Chiapas the rainforest has been cleared, to make way for crops and extensive cattle ranching, at an annual rate of 12.4% since 2002. The conservation status of the

Ranging Patterns of Two Syntopic Howler Monkey Species (Alouatta guariba and A. caraya) in Northeastern Argentina

Groups of different species overlapped their ranging areas consistently more and responded to one another less aggressively during encounters than groups of the same species, suggesting that interspecific spatial niche separation for these two syntopic species is not occurring.

Gastrointestinal parasites of Howler monkeys (Alouatta palliata) inhabiting the fragmented landscape of the Santa Marta mountain range, Veracruz, Mexico

Although parasite richness was lower, prevalence and density were higher than values reported for howlers in conserved forests, these results suggest that the establishment of biological corridors and animal translocation programs must take into account the parasite ecology of each fragment to avoid higher infection rates and preclude potential consequent mortality.

Mycophagy and its influence on habitat use and ranging patterns in Callimico goeldii.

It is suggested that the large home ranges and shifting core areas used by C. goeldii are components of a foraging strategy to track patchy, low density, and ephemeral fungal fruiting bodies.

Seed Predation of Mabea Fistulifera (Euphorbiaceae) by Northern Muriquis (Brachyteles hypoxanthus)

It was indicated that fruits at earlier stages of ripeness were significantly softer than ones of later stages, implying that fruit hardness made their seeds unprofitable to these non-specialized seed predator monkeys.
