Predation of treefrogs (Anura: Hylidae) with toxic skin secretions by the black lion tamarin (Leontopithecus chrysopygus, Callitrichinae)
Primates, 2020Co-Authors: Guilherme S T Garbino, Leonardo Henrique Silva, Rodrigo Gonçalves Amaral, Gabriela Cabral Rezende, Vinicius J. A. Pereira, Laurence CulotAbstract: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. The veined treefrog was removed from a tree hollow by an adult male, whereas the ocellated treefrog was caught on the ground after it jumped from the tree attempting to escape capture. The frogs were completely ingested and no food sharing occurred in either of the events. We did not observe any signs of irritation during the event or when the group was followed in the next day in either of the cases. These are the first reports of lion tamarins ingesting anurans with noxious secretions on the skin.

What is in a genus name? Conceptual and empirical issues preclude the proposed recognition of Callibella (Callitrichinae) as a genus
Primates, 2019Co-Authors: Guilherme S T Garbino, José E. Serrano-villavicencio, Eliécer E. GutiérrezAbstract:In a recent article, Silva et al. (Zool Scr 47:133–143, 2018) proposed the relocation of the dwarf marmoset, Mico humilis , to the so far unrecognized genus Callibella . We contend that a taxonomic scheme that recognizes Callibella as if it were a valid genus is inadequately supported, and to some extent contradicted, by the ecological and morphological information provided by the authors. We discuss why the criterion of sympatry, invoked by Silva et al. to justify the recognition of Callibella at the genus level, is uninformative for taxonomic decisions above the species level. We also show that the morphological characteristics used by Silva et al. to separate Mico humilis from the other Mico are individually variable and present in every analyzed species of the genus. Moreover, we demonstrate that the Evolutionarily Distinct and Globally Endangered (EDGE) metric, employed by those authors to attempt to justify their taxonomic proposition, makes no sense in a taxonomic context. Conceptually, the use of autapomorphies and plesiomorphies to justify using Callibella goes against one of the main objectives of a meaningful classification, that is, to allow for all kinds of inferences based on previous observations (i.e., to be inductively projectible). Based on these arguments, we demonstrate that regarding Callibella as a subgenus of Mico is the most suitable way of making the Linnean taxonomy of marmosets congruent with the phylogenetic information available for the group.

phenotypic evolution in marmoset and tamarin monkeys cebidae Callitrichinae and a revised genus level classification
Molecular Phylogenetics and Evolution, 2018Co-Authors: Guilherme S T Garbino, Antonio MartinsjuniorAbstract:Abstract Marmosets and tamarins (Cebidae, Callitrichinae) constitute the most species-rich subfamily of New World monkeys and one of the most diverse phenotypically. Despite the profusion of molecular phylogenies of the group, the evolution of phenotypic characters under the rapidly-emerging consensual phylogeny of the subfamily has been little studied, resulting in taxonomic proposals that have limited support from other datasets. We examined the evolution of 18 phenotypic traits (5 continuous and 13 discrete), including pelage, skull, dentition, postcrania, life-history and vocalization variables in a robust molecular phylogeny of marmoset and tamarin monkeys, quantifying their phylogenetic signal and correlations among some of the traits. At the family level, our resulting topology supports owl monkeys (Aotinae) as sister group of Callitrichinae. The topology of the callitrichine tree was congruent with previous studies except for the position of the midas group of Saguinus tamarins, which placement as sister of the bicolor group did not receive significant statistical support in both Maximum Parsimony and Bayesian Inference analyses. Our results showed that the highest value of phylogenetic signal among continuous traits was displayed by the long call character and the lowest was exhibited in the home range, intermediate values were found in characters related to osteology and skull size. Among discrete traits, pelage and osteology had similar phylogenetic signal. Based on genetic, osteological, pelage and vocalization data, we present an updated genus-level taxonomy of Callitrichinae, which recognizes six genera in the subfamily: Callimico, Callithrix, Cebuella, Mico, Leontopithecus and Saguinus . To reflect their phenotypic distinctiveness and to avoid the use of the informal “species group”, we subdivided Saguinus in the subgenera Leontocebus, Saguinus and Tamarinus (revalidated here).

Tocantins river as an effective barrier to gene flow in Saguinus niger populations
Genetics and Molecular Biology, 2020Co-Authors: Marcelo Vallinoto, Iracilda Sampaio, Claudia Helena Tagliaro, Juliana Araripe, Péricles Sena Do Rêgo, Horacio SchneiderAbstract:The Saguinus represent the basal genus of the Callitrichinae subfamily. Traditionally this genus is divided into three groups: Hairy, Mottled and Bare-face, however, molecular data failed to validate these groups as monophyletic units, as well as raised some subspecies to the species status. This is the case of the former subspecies Saguinus midas midas and S. midas niger, which are now considered as different species. In the present study, we sequenced a portion of the D-loop mtDNA region in populations from the East bank of the Xingu and from both banks of the Tocantins river, in order to test the effectiveness of large rivers as barriers to the gene flow in Saguinus. According to our results, the populations from the East and West banks of the Tocantins river are more divergent than true species like S. mystax and S. imperator. The Tocantins river may be acting as a barrier to gene flow, and consequently these very divergent populations may represent distinct taxonomic entities (species?).

Molecular studies of Callithrix pygmaea (Primates, Platyrrhini) based on transferrin intronic and ND1 regions: implications for taxonomy and conservation
Genetics and Molecular Biology, 2020Co-Authors: Claudia Helena Tagliaro, Maria Paula Cruz Schneider, Iracilda Sampaio, Horacio Schneider, Michael J. StanhopeAbstract:As classificacoes tradicionais envolvendo os macacos da infraordem Platyrrhini, principalmente baseadas em caracteristicas morfologicas, tem sido contestadas por dados moleculares recentes. A subfamilia Callitrichinae (Platyrrhine, Primates) engloba um diverso grupo de especies, muitas das quais consideradas em perigo de extincao. A presente analise de duas regioes do DNA, um gene mitocondrial (ND1) e um gene nuclear (regioes intronicas da transferrina), sugerem que Callithrix pygmaea apresenta variabilidade suficiente para justificar a existencia de subespecies ou ate mesmo de especies distintas. As arvores filogeneticas baseadas na regiao do ND1 indicam que esta especie esta relacionada mais proximamente aos marmosets amazonicos do que aos da mata Atlântica. Estes resultados reabrem a discussao sobre diversidade e programas de conservacao baseados apenas em classificacoes taxonomicas tradicionais.

a molecular analysis of the evolutionary relationships in the Callitrichinae with emphasis on the position of the dwarf marmoset
Zoologica Scripta, 2012Co-Authors: Horacio Schneider, Marcelo Vallinoto, Jose A R Bernardi, Divino Bruno Da Cunha, Claudia Helena Tagliaro, Steve F Ferrari, Iracilda SampaioAbstract:Schneider, H., Bernardi, J. A. R., da Cunha, D. B., Tagliaro, C. H., Vallinoto, M., Ferrari, S. F. & Sampaio, I. (2012). A molecular analysis of the evolutionary relationships in the Callitrichinae, with emphasis on the position of the dwarf marmoset. —Zoologica Scripta, 41, 1–10. The phylogenetic relationships among the Neotropical primates of the subfamily Callitrichinae (marmosets and tamarins) are controversial, especially with regard to the proposal of a new marmoset genus, Callibella, based on the analysis of sequences of a single mitochondrial gene. In this study, we combine the fast-evolving mitochondrial Control Region with four nuclear regions containing Alu elements in an attempt to provide a more conclusive assessment of the phylogenetic relationships among the marmosets (Callithrix, Cebuella and Mico), with special attention to the validity of Callibella. A large, representative sample of specimens was obtained, which include all the recognized genera and principal morphological and geographic groupings. The results of the analysis indicate unequivocally the existence of three independent lineages, corresponding to the Atlantic Forest (Callithrix), Amazonian (Mico) and pygmy marmoset (Cebuella) groups. The evidence also confirms the monophyletic relationship of the dwarf marmoset (Callibella) with the Amazonian marmosets (Mico), which indicates conclusively that this taxon is a member of the genus Mico, upholding the original description of the species as Mico humilis.

Molecular phylogeny of the genus Saguinus (Platyrrhini, Primates) based on the ND1 mitochondrial gene and implications for conservation
Genetics and Molecular Biology, 2005Co-Authors: Claudia Helena Tagliaro, Maria Paula Cruz Schneider, Iracilda Sampaio, Horacio Schneider, Marcelo Vallinoto, Michael J. StanhopeAbstract:The systematics of the subfamily Callitrichinae (Platyrrhini, Primates), a group of small monkeys from South America and Panama, remains an area of considerable discussion despite many investigations, there being continuing controversy over subgeneric taxonomic classifications based on morphological characters. The purpose of our research was to help elucidate the phylogenetic relationships within the monkey genus Saguinus (Callitrichinae) using a molecular approach to discover whether or not the two different sections containing hairy-faced and bare-faced species are monophyletic, whether Saguinus midas midas and Saguinus bicolor are more closely related than are S. midas midas and Saguinus midas niger, and if Saguinus fuscicollis melanoleucus and Saguinus fuscicollis weddelli really are different species. We sequenced the 957 bp ND1 mitochondrial gene of 21 Saguinus monkeys (belonging to six species and nine morphotypes) and one Cebus monkey (the outgroup) and constructed phylogenetic trees using maximum parsimony, neighbor joining, and maximum likelihood methods. The phylogenetic trees obtained divided the genus Saguinus into two groups, one containing the small-bodied species S. fuscicollis and the other, the large-bodied species S. mystax, S. leucopus, S. oedipus, S. midas, S. bicolor. The most derived taxa, S. midas and S. bicolor, grouped together, while S. fuscicollis melanoleucus and S. f. weddelli showed divergence values that did not support the division of these morphotypes into subspecies. On the other hand, S. midas individuals showed divergence compatible with the existence of three subspecies, two of them with the same morphotype as the subspecies S. midas niger. The results of our study suggest that there is at least one Saguinus subspecies that has not yet been described and that the conservation status of Saguinus species and subspecies should be carefully revised using modern molecular approaches.

mitochondrial dna like sequence in the nuclear genome of saguinus Callitrichinae primates transfer estimation
Genetics and Molecular Biology, 2000Co-Authors: Marcelo Vallinoto, Horacio Schneider, Iracilda Sampaio, Leonardo Sena, Maria Paula Cruz SchneiderAbstract:Sequencias tipo mitocondriais tem comumente sido encontradas no genoma nuclear de diversos organismos. Quando acidentalmente incluidas em estudos de sequencias mitocondriais, diversas conclusoes erroneas podem ser obtidas. No entanto, estes pseudogenes nucleares tipo mitocondriais podem ser usados para a estimativa da taxa relativa de evolucao de genes mitocondriais e tambem como grupo externo em analises filogeneticas. No presente trabalho, sequencias mitocondriais com caracteristicas do tipo de pseudogene, tais como delecoes e/ou insercoes e codons de parada, foram encontradas em tamarins (Saguinus spp., Callitrichinae, Primates). A analise filogenetica permitiu a estimativa do tempo da migracao da sequencia mitocondrial para o genoma nuclear e algumas inferencias filogeneticas. A escolha de um grupo externo nao adequado (Aotus infulatus) nao permitiu uma reconstrucao filogenetica confiavel da subfamilia Callitrichinae. A divergencia bastante antiga de Cebidae (Callitrichinae, Aotinae e Cebinae) pode ter favorecido o aparecimento de homoplasias, obscurecendo a analise.

Predation of treefrogs (Anura: Hylidae) with toxic skin secretions by the black lion tamarin (Leontopithecus chrysopygus, Callitrichinae)
Primates, 2020Co-Authors: Guilherme S T Garbino, Leonardo Henrique Silva, Rodrigo Gonçalves Amaral, Gabriela Cabral Rezende, Vinicius J. A. Pereira, Laurence CulotAbstract: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. The veined treefrog was removed from a tree hollow by an adult male, whereas the ocellated treefrog was caught on the ground after it jumped from the tree attempting to escape capture. The frogs were completely ingested and no food sharing occurred in either of the events. We did not observe any signs of irritation during the event or when the group was followed in the next day in either of the cases. These are the first reports of lion tamarins ingesting anurans with noxious secretions on the skin.
