“…In addition, monophyly across the hypothesised range for most species has yet to be explicitly tested. Four new species have been formally described since 2010 (as well as one resurrected taxon; Defler, Bueno, & García, ; Gualda‐Barros, Nascimento, & Amaral, ; Dalponte, Silva, & Silva‐Júnior, ; Vermeer & Tello‐Alvarado, ), and given the many uncertainties/unknowns, further changes to the species‐level taxonomy of each of the callicebine genera are likely. New species descriptions and/or modifications to hypothesised species’ distributions may impact how accurately callicebine taxa are represented in our biogeographic analyses.…”

Titi monkeys, subfamily Callicebinae, are a diverse, species‐rich group of Neotropical primates with an extensive range across South America. Their distribution in space and time makes them an interesting primate model for addressing questions of Neotropical historical biogeography. Our aim was to reconstruct the biogeographic history of Callicebinae to better understand their diversification patterns and the history of their colonisation of South America since the late Miocene. We reconstructed a time‐calibrated phylogeny of 19 titi species under Bayesian inference using two mitochondrial and 11 nuclear loci. Species were assigned across eight Neotropical areas of endemism, and statistical biogeographic methods implemented in BioGeoBEARS were employed to estimate ancestral areas using 12 biogeographic models. Our results indicate that the most recent common ancestor to extant titi monkeys was widespread from the present‐day Andean foothills in the Colombian Amazon, through the wet and dry savannas of Bolivia and Brazil, to the southern Atlantic forest of eastern Brazil. Genus‐level divergences were characterised by vicariance of ancestral range in the late Miocene. Species‐level diversification in Cheracebus and the Plecturocebus moloch group occurred as they spread across the Amazon in the Pleistocene and were largely characterised by a sequential, long‐distance “island‐hopping” dispersal model of speciation from a narrow area of origin through jump dispersal across rivers. This study comprises the first large‐scale investigation of the evolutionary history of titi monkeys in the context of Amazonian and South American historical biogeography and sheds light on the processes that generated the great diversity found among Callicebinae.

“…A região do MTP está localizada próxima aos limites dos biomas Amazônia e Cerrado (Figura 1). A área é formada por floresta tropical madura com lianas formando um dossel descontínuo, estando este compreendido entre 20 e 30 metros de altura, com árvores emergentes alcançando até 40 m. O dossel é relativamente denso e a floresta bem estratificada (Gualda-Barros et al 2012). O clima é equatorial quente e semi-úmido com pelo menos três meses de estação seca e temperaturas mensais médias sempre acima dos 18 ºC (IBGE 2002 (Sikes et al 2011).…”

Morcegos (Mammalia: Chiroptera) da região do Médio Rio Teles Pires, Sul da Amazônia, Brasil

et al. 2015

A Amazônia é a maior floresta tropical do mundo e pelo menos 147 espécies de morcegos ocorrem neste ambiente. A despeito desta grande riqueza, a diversidade de morcegos da Amazônia é pobremente conhecida e existem grandes lacunas neste conhecimento. O objetivo do presente trabalho foi descrever a assembleia de morcegos ocorrentes na região do Médio Teles Pires (MTP), no sul da Amazônia. Além disso, avaliou-se a similaridade dessa assembleia em relação a 14 assembleias estudadas em outras localidades amazônicas e avaliou-se a correlação entre as similaridades destas localidades e suas distâncias. Trinta e três espécies de morcegos foram registradas, representando 71% das espécies estimadas (Jackknife2). As três espécies com maior abundância relativa foram: Carollia perspicillata, Pteronotus parnellii e Phyllostomus hastatus que somadas contam com mais de 50% das capturas. O grupo funcional dos frugívoros obteve o maior número de espécies capturadas. Foi encontrada uma correlação negativa entre as distâncias e as similaridades das assembleias de morcegos amazônicos (r = -0,22; p = 0,014). A distância geográfica pode explicar apenas 6% da similaridade entre as assembleias analisadas, ainda assim, as similaridades destas assembleias permitem que as mesmas sejam agrupadas por suas distâncias geográficas. Além disso, a fauna de morcegos do MTP é diferenciada de outras áreas da Amazônia o que lhe confere um papel especial na conservação dos morcegos amazônicos.

Bats (Mammalia: Chiroptera) from the Middle Teles Pires River region, Southern Amazonia, Brazil ABSTRACTAmazonia is the largest tropical rainforest in the world and at least 147 bat species occur in this environment. Despite its richness, the diversity of bat fauna is poorly known for this region and there are large gaps in its knowledge. This study aims to describe the bat assemblage of the Middle Teles Pires River (MTP) region, southern Amazonia. Furthermore, we evaluated the similarity of this assemblage in relation to 14 assemblages studied in other Amazonian localities, and correlations were found between the similarity values among the sites and their geographic distances. Thirty-three bat species were recorded, accounting for 71% of the estimated species richness (Jackknife2). The three species that had the higher relative abundance values were Carollia perspicillata, Pteronotus parnellii and Phyllostomus hastatus, which together accounted for more than 50% of the captures. The frugivore functional group had the highest number of recorded species. A negative correlation was found between the geographic distances and the similarities among the Amazonian bat assemblages (r = -0.22; p = 0.014). Geographic distance could explain only 6% of the similarities among the analyzed assemblages, even though, the similarity found allowed them to be grouped by their distances. Besides, the MTP bat fauna is different from other Amazonian areas, which gives it a special role in the Amazonian ba...

Extension of the geographic distribution of Plecturocebus baptista (Pitheciidae, Primates) and a possible hybrid zone with Plecturocebus hoffmannsi: evolutionary and conservation implications

Titi monkeys (family Pitheciidae) are Neotropical primates highly diversified in morphology, ecology and genetics, with a wide geographic distribution, including the Amazon, Atlantic Forest, Cerrado, Pantanal and Caatinga. This diversity, together with knowledge gaps, generates uncertainties in titi monkey taxonomy and distribution. An example is Plecturocebus baptista, with only 14 occurrence records and an ill-defined distribution based on untested geographical barriers. Here, we report the occurrence of this species at a new locality outside its known range, across the Paraná-Urariá River, which was considered a distributional limit for the species. The new record implies an overlap of P. baptista with the range of P. hoffmannsi. We document the sighting of an apparent hybrid animal. Our observations suggest that i) the distribution of P. baptista needs to be reviewed, and ii) the evolutionary relationships between P. baptista and P. hoffmannsi may be more complex than previously assumed. Since both species share contiguous areas of potential hybridization, we question whether the two species arose via allopatric speciation.Extensão da distribuição geográfica de Plecturocebus baptista (Pitheciidae, Primates) e uma possível zona híbrida com Plecturocebus hoffmannsi: implicações evolutivas e de conservação RESUMO Macacos zogue-zogue (família Pitheciidae) são primatas neotropicais altamente diversificados em morfologia, ecologia e genética, com distribuição geográfica abrangente, incluindo a Floresta Amazônica, Mata Atlântica, Cerrado, Pantanal e a Caatinga. Essa diversificação, juntamente com lacunas de conhecimento, gera incertezas na taxonomia e distribuição das espécies. Um exemplo é Plecturocebus baptista, com apenas 14 registros de ocorrência e distribuição indefinida, baseada em barreiras geográficas não testadas. Aqui nós relatamos a ocorrência da espécie em uma nova localidade, fora de sua área conhecida de distribuição, que transpõe uma suposta barreira geográfica, o Rio Paraná-Urariá. O novo registro de P. baptista se sobrepõe à distribuição de P. hoffmannsi e, neste contexto, observamos um indivíduo aparentemente híbrido entre as duas espécies. Nossas observações sugerem que i) a distribuição de P. baptista necessita ser revisada, e ii) a relação evolutiva entre P. baptista e P. hoffmannsi pode ser mais complexa do que se pensava. Como ambas espécies compartilham áreas contínuas de potencial hibridização, questionamos se as duas espécies resultaram de especiação alopátrica.
