Genetic Consequences of Habitat Fragmentation in Black-and-Gold Howler (Alouatta caraya) Populations from Northern Argentina
Differences between habitats may reflect a reduced gene flow, providing genetic evidence that suggests that habitat fragmentation severely limits the howler’s ability to disperse. Expand
Evolutionary trends in host physiology outweigh dietary niche in structuring primate gut microbiomes
The findings indicate that mammalian gut microbiome plasticity in response to dietary shifts over both the lifespan of an individual host and the evolutionary history of a given host species is constrained by host physiological evolution, and the gut microbiome cannot be considered separately from host physiology when describing host nutritional strategies and the emergence of host dietary niches.

Habitat fragmentation and population size of the black and gold howler monkey (Alouatta caraya) in a semideciduous forest in Northern Argentina
Group sizes and group composition of howlers suggest that the population remained stable over the past 22 years, and the density, number of groups, and individuals appears not to be affected by fragmentation and logging, but crude density was low compared with other less‐disturbed habitats. Expand
Birth Seasonality in Alouatta caraya in Northern Argentina
Given appropriate ecological and social conditions, natural selection should favor individuals that can concentrate their reproductive events to a particular time of the year that offers highExpand
The Effects of Captivity on the Mammalian Gut Microbiome
Differences in gut bacterial beta diversity between the captive and wild state were observed for most of the taxa surveyed, except the even-toed ungulates, and beta diversity variation was also strongly influenced by host taxonomic group, diet type, and gut fermentation physiology. Expand
Evidence of Alternative Dietary Syndromes and Nutritional Goals in the Genus Alouatta
This chapter examined evidence for interspecific differences in dietary patterns and nutritional ecology within the genus Alouatta and identified three dietary “syndromes” that are generally consistent with howler monkey phylogeny and biogeography. Expand
The importance of protein in leaf selection of folivorous primates
Overall this study suggests that protein selection is influenced by the protein availability in the environment, explaining the sometimes contradictory results in previous studies on protein selection. Expand
Global phylogeography and ancient evolution of the widespread human gut virus crAssphage
It is concluded that crAssphage is a benign globetrotter virus that may have co-evolved with the human lineage and an integral part of the normal human gut virome. Expand
Mating promiscuity and reproductive tactics in female black and gold howler monkeys (Alouatta caraya) inhabiting an island on the Parana river, Argentina
It is suggested that female promiscuity is the prime driver or constraint on male reproductive opportunities in this species and may serve to increase opportunities for genetic diversity between a female's successive offspring as well as minimize the risk of infanticide by spreading paternity estimates across a larger number of adult males.

Detection of the mosquito-borne flaviviruses, West Nile, Dengue, Saint Louis Encephalitis, Ilheus, Bussuquara, and Yellow Fever in free-ranging black howlers (Alouatta caraya) of Northeastern
This is the first detection of WNV-specific antibodies in black howlers from Argentina and the first report in free-ranging non-human primates from Latin-American countries, and the results suggest that the study population remains susceptible to YFV. Expand
