Altricial Patterns in Prenatal Skeletal Development of Two Large Neotropical Primates
Understanding prenatal skeletal development is essential for pregnancy monitoring and veterinary care, as well as for understanding reproductive strategies, evolutionary differences, and ecological adaptations. This study provides an ultrasonographic description of prenatal bone development in two large neotropical primates, the Poeppig's woolly monkey ( Lagothrix lagothricha poeppigii , n = 24) and the Juruá howler monkey ( Alouatta juara , n = …
Radiographic Assessment of Spinal Degeneration in Vervet Monkeys ( Chlorocebus aethiops )
Degenerative changes of the vertebral column are common in aging primates; however, patterns of spinal osteopathy remain poorly characterized across small‐ and medium‐bodied primate species, limiting comparative interpretations of skeletal aging. Expanding assessments beyond well‐studied taxa provides a broader framework for understanding primate musculoskeletal senescence and generates baseline data essential for interpreting vertebral degenerat…
Age-related Changes in Dehydroepiandrosterone-sulfate in Black-and-gold Howler Monkeys (Alouatta caraya)
Dehydroepiandrosterone-sulfate (DHEAS) is the most abundant steroid in humans and some nonhuman primates. This adrenal androgen contributes to immune enhancement, neuroprotection, and reproduction. In humans and apes, DHEAS levels increase before puberty, a phenomenon called adrenarche. However, a postnatal increase in the levels of these hormones is not apparent in cercopithecoids. In marmosets, DHEAS is only synthesized from female adrenal glan…
Reproductive physiology with emphasis on endometrial cycles of woolly and uakari monkeys—A literature review
The ability of a species to withstand human impact depends on its life history characteristics, including social, ranging, and reproductive activity. The genera Lagothrix and Cacajao are more susceptible to anthropic action than small‐sized primates due to their slower life histories, more restricted geographical ranges, and lower population densities. This narrative literature review aimed to gather scientific information available from the last…

Trypanosoma cruzi infection in captive Neotropical primates in the Brazilian Amazon
The aim of this study was to detect the infection by Trypanosoma cruzi in captive Neotropical primates in the Brazilian Amazon. From February 2013 to July 2014, 112 blood samples were collected from Neotropical primates from the Amazonas, Amapá, and Pará States, north of Brazil. The subjects belonged to the families Cebidae (N = 59), Atelidae (N = 41), Callitrichidae (N = 5), Pitheciidae (N = 4), and Aotidae (N = 3). Blood smears also were examin…
A novel method for capturing and monitoring a small neotropical primate, the squirrel monkey ( Saimiri collinsi )
Squirrel monkeys (genus Saimiri) are agile, arboreal primates that are seldom captured in the wild due to their small body size (<1 kg) and large, non-cohesive social groups (40-50 individuals). However, long-term studies on these primates often require captures and permanent identification of individuals, in order to monitor their behavior and health. Here we report on a novel trapping method successfully used to capture Saimiri collinsi, in Eas…
Renal Evaluation of A otus azarai infulatus by Ultrasonography and Serum Chemistry Profile
This study aimed to characterize anatomical and biochemical properties of owl monkey kidneys in order to provide normal reference values. Sixty‐nine A otus azarai infulatus (45 males and 24 females) were divided into four different age groups ( AG 1: 3 months–1 year; AG 2: 2–3 years; AG 3: 4–6 years; and AG 4: over 7 years old). The monkeys were evaluated with a serum chemistry profile, focusing on serum creatinine ( SC r) and blood urea nitrogen…
