“…Here we present a report on the hybridization of human chromosome-specific paints on metaphases of 1 individual from Aotus lemurinus and 4 individuals assigned to Alouatta caraya . The results are then compared with previous hybridization data obtained on the chromosomes of other primates, with particular regard for the 2 reports on Aotus species [Stanyon et al, 2004;Ruiz-Herrera et al, 2005] and the prior reports on A. caraya [Mudry et al, 2001;de Oliveira et al, 2002].…”

Cytogenetic studies showed that a number of New World primate taxa, particularly the genera Alouatta, Aotus, and Callicebus, have highly derived karyotypes. Cytogenetics in these primates, at every level of analysis, has contributed to the recognition of species and revealed that their number was certainly underestimated by researchers relying solely on traditional morphological data. Further attention was drawn to Alouatta and Aotus because they are characterized by translocations of the Y chromosome to autosomes, generating multiple sex chromosome systems. Here we present a report on the hybridization of human chromosome-specific paints on metaphases from 4 individuals originally assigned to Alouatta caraya and 1 individual of Aotuslemurinus. This is only the third karyotype studied with chromosome painting out of more than 10 known karyomorphs in Aotus. The banded chromosomes matched those of karyotype II as defined by Ma et al. [1976a], and we were able to more precisely assign the origin of the sample to A. l. griseimembra. Our results on the Argentinean Alouatta caraya samples were generally comparable to the banding and hybridization pattern of previous studies of A. caraya including the presence of an X₁X₁X₂X₂/X₁X₂Y₁Y₂ sex chromosome system. The karyotype of the Brazilian Alouatta sample labeled as A. caraya differs from the 3 Argentinean samples by at least 10 chromosome rearrangements. The diploid number, G banding, and hybridization pattern of this female cell line was almost identical to previous painting results on Alouatta guariba guariba. Therefore we must conclude that this cell line is actually from an A. guariba guariba individual. The contribution of cytogenetic tools in identifying species or in this case assigning individuals or cell lines to their precise taxonomic allocation is stressed. Gathering further molecular cytogenetic data on New World primates should be conservation and management priorities.

“…Its taxonomic status has been a matter of academic dispute due to the wide number of different karyotypes reported without clear phenotypic distinctions between intra-and inter-population variations (Ruiz-Herrera et al 2005, Defler & Bueno 2007. The genus is divided into 2 groups: the red-necked species group distributed south of the Amazon-Solimões River and the grey-necked species group found mainly north of the Amazon River (Hershkovitz 1983, HernandezCamacho & Defler 1989 (Defler 2004).…”

This study describes significant levels of trade in 2 or possibly 3 species of night monkeys (Aotus nancymaae, A. vociferans and A. nigriceps) from the Brazil-Colombia-Peru tri-border area. All 3 countries are Party to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and there is no documented trade in night monkeys among these 3 countries in the CITES trade database. However, interviews with 43 traders/collectors in 11 communities in the 3 countries suggest that for the period 2007-2008, ca. 4000 night monkeys were traded, representing a monetary value of over USD 100 000 for the traders and intermediaries. The interviewees indicated that the animals were sold to a biomedical laboratory in the tri-border area on the Colombian side of the border. The international nature of the trade and the large volume of night monkeys being traded indicate a violation of, and a failure to adhere to, international trade regulations. In order to conserve these important species, we suggest cooperative action from environmental and conservation authorities and the respective CITES Management Authorities in Colombia, Peru and Brazil to curb the trade, and urge the Colombian authorities to investigate the illegal importation of night monkeys by a biomedical laboratory in the border area.

“…Seven chromosome fission events resulted in 29 vervet autosomes, compared to 21 or 22 in most other catarrhines (Stanyon et al 2012). With few exceptions, such as the gibbon (Carbone et al 2014) and owl monkey (Ruiz-Herrera et al 2005), primate chromosomes reveal little change from the inferred ancestral karyotype. The chromosomal variation in gibbon likely resulted from a gibbon-specific retrotransposon that moved into regions harboring chromosomal segregation genes (Carbone et al 2014).…”

The genome of the vervet (Chlorocebus aethiops sabaeus)

We describe a genome reference of the African green monkey or vervet (Chlorocebus aethiops). This member of the Old World monkey (OWM) superfamily is uniquely valuable for genetic investigations of simian immunodeficiency virus (SIV), for which it is the most abundant natural host species, and of a wide range of health-related phenotypes assessed in Caribbean vervets (C. a. sabaeus), whose numbers have expanded dramatically since Europeans introduced small numbers of their ancestors from West Africa during the colonial era. We use the reference to characterize the genomic relationship between vervets and other primates, the intra-generic phylogeny of vervet subspecies, and genome-wide structural variations of a pedigreed C. a. sabaeus population. Through comparative analyses with human and rhesus macaque, we characterize at high resolution the unique chromosomal fission events that differentiate the vervets and their close relatives from most other catarrhine primates, in whom karyotype is highly conserved. We also provide a summary of transposable elements and contrast these with the rhesus macaque and human. Analysis of sequenced genomes representing each of the main vervet subspecies supports previously hypothesized relationships between these populations, which range across most of sub-Saharan Africa, while uncovering high levels of genetic diversity within each. Sequence-based analyses of major histocompatibility complex (MHC) polymorphisms reveal extremely low diversity in Caribbean C. a. sabaeus vervets, compared to vervets from putatively ancestral West African regions. In the C. a. sabaeus research population, we discover the first structural variations that are, in some cases, predicted to have a deleterious effect; future studies will determine the phenotypic impact of these variations.
