Morphology, Taxonomic Status and Affinities of the Lion Tamarins, Leontopithecus (Callitrichinae, Cebidae) [PDF]
Folia Primatologica, 1984 A survey of craniodental variability of the three allopatric populations of Leontopithecus reveals that they are morphologically heterogeneous and individually distinctive, with a nonclinal distribution of characters and pattern similarities. These observations correspond with their better known, starkly different coat coloration, and imply important ...

How many marmoset (Primates: Cebidae: Callitrichinae) genera are there? A phylogenetic analysis based on multiple morphological systems [PDF]
Cladistics, 2015 AbstractThe marmosets, tribe Callitrichini, are the most speciose clade in the subfamily Callitrichinae, containing 21 species. However, there is no consensus among molecular and morphological systematists as to how many genera should be recognized for the group.

Primates, 2020 We report on the predation of a veined treefrog (Trachycephalus venulosus) and an ocellated treefrog (Itapotihyla langsdorffii), both species with noxious skin secretions, by black lion tamarins (Leontopithecus chrysopygus). The two predation events took place in Morro do Diabo State Park, an Atlantic Forest reserve in southeastern Brazil.

Boletim do Museu Paraense Emílio Goeldi - Ciências Naturais, 2020 The common marmoset (Callithrix jacchus) is a primate found in urban forests and in high density of human population sites, however there is insufficient informations about its behavior in mangroves. One group of marmosets was monitored in the Espaço Ciência museum, in the state of Pernambuco, Northeastern Brazil, located in a mangrove area that has ...

Primate Research, 2002 There is the hypothesis (Ford, 1980) that the callitrichines, which are rapidly dwarfed, should have relatively large postcanine teeth in comparison with other platyrrhines (non-callitrichines) and the loss of the third molars is probably the result of crowding from the disproportional enlarged molar teeth. In the present study, to test this hypothesis,

Lundiana: International Journal of Biodiversity, 2021 This study provides a quantitative assessment of the craniofacial variation among recognized species and subspecies in the Saguinus mystax species group and tests the reliability of the proposed method in detecting differences among taxa. Thirty measurements were taken of 66 tamarin specimens.

Adaptation in the face of internal conflict: the paradox of the organism revisited
Biological Reviews, Volume 98, Issue 5, Page 1796-1811, October 2023., 2023 ABSTRACT The paradox of the organism refers to the observation that organisms appear to function as coherent purposeful entities, despite the potential for within‐organismal components like selfish genetic elements and cancer cells to erode them from within. While it is commonly accepted that organisms may pursue fitness maximisation and can be thought

Comparative gastrointestinal organ lengths among Amazonian primates (Primates: Platyrrhini)
American Journal of Biological Anthropology, Volume 181, Issue 3, Page 440-453, July 2023., 2023 Principal coordinates analysis (PCoA) comparing the individual gastrointestinal variation based on Euclidean distance (51% of explanation for the axis 1 and 26% of axis 2), where CeQ, cecal quotient; CoQ, colonic quotient; EQ, esophageal quotient; GQ, gastric quotient; IQ, small intestine quotient; RQ, rectal quotient. Ellipses represent 95% confidence
