“…palliata / A . pigra individuals, such as those previously reported by Cortés-Ortiz et al (2007). Those studies would allow us to understand the genetic interaction of the parental species at chromosomal level, as well as to explore possible reproductive isolating mechanisms that have been suggested by means of molecular data.…”

We describe for the first time the karyotype of the black howler monkey, Alouatta pigra. Conventional staining, G- and C-banding, and fluorescence in situ hybridization (FISH) with a peptide nucleic acid (PNA) pantelomeric probe were performed. Eight free ranging adult individuals, four males and four females, within the natural distribution of the species presented a diploid karyotype with 2n = 58. Mitotic analyses showed an autosomal complement composed of 6 submetacentric, 3 metacentric, and 19 acrocentric chromosome pairs for females, and 6 submetacentric, 3 metacentric, and 18 acrocentric pairs for males. Meiotic analyses in males revealed 27 autosomal bivalents and a quadrivalent composed of a submetacentric X₁ and acrocentric X₂, Y₁, and Y₂. The G-banded karyotype allowed us to identify pair #17 as the autosomal pair involved in the rearrangement and the morphology of the quadrivalent components. C-banding technique in metaphase I corroborated the structure of the quadrivalent showing four C+ centromeres. FISH analysis showed telomeric signals at the terminal regions of all chromosomes. No interstitial signals were detected. DNA sequence data were in accordance with those previously published for this species.

“…A study on howler monkeys (Alouatta palliata and A. pigra) showed that hybridization and subsequent backcrossing are directionally biased, probably producing only fertile hybrid females and inviable or infertile males. This suggests that a process of mate choice may occur for Neotropical primates in hybrid zones (Cortés-Ortiz et al 2007).…”

ABSTRACT. Two species of Callithrix, C. jacchus (Linnaeus, 1758) and C. penicillata (É. Geoffroy, 1812), are considered invasive in Rio de Janeiro. This study determined the genetic and morphological diversity and verified the species involved in the hybridization of 10 individuals from the municipalities of Silva Jardim (N = 9) and Rio das Ostras (N = 1). We compared the The results corroborate that C. jacchus and C. penicillata participate in the hybridization process. There was no geographic structure between hybrids from the coastal lowlands and from the metropolitan region of Rio de Janeiro.

“…5). For example, in a hybrid zone between the Guatemalan black howler monkey, Alouatta pigra, and the Mantled howler, A. palliata, hybrids are rare, but the majority have A. pigra mtDNA (Cortes-Ortiz et al 2007). In this case, the authors suggest that this is caused by a combination of biased mating and postzygotic selection on offspring, where hybrids between female A. palliata and male A. pigra do not develop.…”

The biogeography of mitochondrial and nuclear discordance in animals

Combining nuclear (nuDNA) and mitochondrial DNA (mtDNA) markers has improved the power of molecular data to test phylogenetic and phylogeographic hypotheses and has highlighted the limitations of studies using only mtDNA markers. In fact, in the past decade, many conflicting geographic patterns between mitochondrial and nuclear genetic markers have been identified (i.e. mito-nuclear discordance). Our goals in this synthesis are to: (i) review known cases of mito-nuclear discordance in animal systems, (ii) to summarize the biogeographic patterns in each instance and (iii) to identify common drivers of discordance in various groups. In total, we identified 126 cases in animal systems with strong evidence of discordance between the biogeographic patterns obtained from mitochondrial DNA and those observed in the nuclear genome. In most cases, these patterns are attributed to adaptive introgression of mtDNA, demographic disparities and sex-biased asymmetries, with some studies also implicating hybrid zone movement, human introductions and Wolbachia infection in insects. We also discuss situations where divergent mtDNA clades seem to have arisen in the absence of geographic isolation. For those cases where foreign mtDNA haplotypes are found deep within the range of a second taxon, data suggest that those mtDNA haplotypes are more likely to be at a high frequency and are commonly driven by sex-biased asymmetries and ⁄ or adaptive introgression. In addition, we discuss the problems with inferring the processes causing discordance from biogeographic patterns that are common in many studies. In many cases, authors presented more than one explanation for discordant patterns in a given system, which indicates that likely more data are required. Ideally, to resolve this issue, we see important future work shifting focus from documenting the prevalence of mito-nuclear discordance towards testing hypotheses regarding the drivers of discordance. Indeed, there is great potential for certain cases of mitochondrial introgression to become important natural systems within which to test the effect of different mitochondrial genotypes on whole-animal phenotypes.
