Here we present 192 new records of 22 species and subspecies of primates, collected in 56 different localities during 10 field expeditions across the arc of deforestation between 2015 and 2018. Based on such new records, we extend the ranges of Alouatta puruensis, Ateles chamek, and Saimiri collinsi; identify potential hybridization zones in Alouatta and Ateles species; redefine the range of Plecturocebus moloch; and clarify the ranges of P. baptista and P. hoffmannsi.

The Djaffa Mountains guereza (Colobus guereza gallarum) is an endemic Ethiopian taxon. Information about its distribution and population size is missing. We collected data on population density and size in four forests in the Ahmar Mountains in a line-transect survey and estimated 109.6 individuals per square kilometer within the study area. This comparatively high density is thus not the main conservation concern, but the fragmentation of the guereza habitat and population is.

The Amazon marmosets are poorly known and severely threatened – endemic to the arc of deforestation in southern Amazonia. Based on data from field expeditions across this global deforestation frontier, we provide new records and extend the range of Mico chrysoleucos, provide new records and refine the range of M. acariensis, report the first records of a species of Mico on permanently flooded forests, and hypothesize the existence of a hybrid zone of these two species and also M. melanurus.

To our knowledge, this report represents the first description of thyroid gland tumors in an African Green Monkey (Chlorocebus aethiops). Two cystadenomas as well as a solid follicular adenoma are described in a 27-year-old female. No indications of excessive hormone production due to the tumors were detected.

From November 2011 through to November 2019, we carried out seasonal road transect surveys and estimated population densities of Manyara monkeys and vervet monkeys in Lake Manyara National Park. Both species occurred at relatively high densities, and their population trends remained fairly stable over the study period. Our research highlights the value of long-term monitoring and the importance of Lake Manyara National Park as a stronghold for the endemic and endangered Manyara monkey.

A camera trap captured the moment in which a group of collared peccaries attacked and killed a howler monkey at a clay lick in the Taricaya Ecological Reserve, Madre de Dios, Peru. This novel behaviour helps us understand the myriad risks howler monkeys face when descending to the forest floor while also indirectly emphasizing the importance of geophagy for these animals.

Alfaxalone is a general anesthetic used widely in veterinary medicine and has a chemical structure similar to progesterone. Here we report an unexpectedly high serum progesterone value in a female common marmoset following the treatment with alfaxalone. Cross-reactivity of the antibody used in the progesterone assay with alfaxalone most likely explains this finding, and therefore evaluation of serum progesterone results in animals treated with alfaxalone should be done with caution.

Despite many explorations and surveys, the geographic distribution of many primate species, particularly in the neotropics, is not yet well known. In this paper, we provide evidence that extends the range of Spix's saddle-back tamarin in Peru.

The Manyara monkey was described as a new subspecies of the Cercopithecus mitis species complex in 2020. We sequenced a part of its mitochondrial genome and reconstructed the phylogeny of the mitochondrial lineages. The reconstruction suggests that the Manyara monkey clusters in the youngest of three major C. mitis clades. Our data support the phylogeographic hypothesis of a west-east range expansion of gentle monkeys into eastern and southern Africa.

As part of our study on coppery titi monkeys in the Peruvian Amazon, we observed an individual rubbing his belly with leaves from a potentially medicinal plant. He climbed down from high above and grabbed a handful of leaves from an understory tree, which made it look like a deliberate action. Sitting on a liana he then chewed on the leaves before rubbing them slowly on his belly for a couple of minutes. The plant genus is known in traditional medicine and is used for various effects.

This paper discusses the status of a tamarin specimen housed at the American Museum of Natural History that is wrongly labelled as Saguinus fuscicollis tripartitus and might represent a species or subspecies unknown so far or a hybrid.

We report the first masturbatory behaviour in a male Phayre's langur, in a semi-evergreen forest in Bangladesh. We discuss possible reasons for masturbation and suggest an adequate characterization of the socio-sexual behaviour and reproductive strategies of this globally endangered primate to demonstrate the causes, cost and consequences of masturbation. We also urge further scientific exploration into masturbation among primates due to its evolutionary and conservation significance.

Primate Biol., 8, 37–42, https://doi.org/10.5194/pb-8-37-2021, 2021<br>
To our knowledge, this study is the first report of spontaneous Hashimoto-like chronic lymphocytic thyroiditis in a rhesus macaque (Macaca mulatta). Despite the microscopic similarities to human cases, autoantibodies (thyroglobulin antibodies, thyriod peroxidase antibodies, and thyroid-stimulating hormone receptor antibodies) were not identified in this rhesus macaque using a human electrochemiluminescence immunoassay system.

Baboons occur in a large range of different habitats. However, data on the ecology of Guinea baboons were scarce. We provide information on the ranging behaviour, habitat use, and diet of a population of Guinea baboons in the Niokolo-Koba National Park, Senegal. Home ranges were about 25 km2, and they moved up to 13 km per day. They seem to prefer the more forested parts of their home range near the river. Fruit dominates their diet, and the nuts of the palmyra palm are a year-round food source.

We examined the influence of forest edge effects on activity budgets, feeding ecology, and stress hormone output in five groups of Verreaux’s sifakas (Propithecus verreauxi) in western Madagascar. Sifakas in the edge habitat travelled more, tended to have smaller home ranges, had lower fruit consumption, higher stress hormone levels, and lower birth rates than sifakas in the forest interior. Hence, Verreaux’s sifakas appear to be sensitive to microhabitat characteristics linked to forest edges.

Great apes and humans can develop similar health conditions, including heart disease. As lipids predict health risk in humans, we explored whether they do so in gorillas and also examined relationships with age and sex. Multiple sex and age differences were observed. Age, sex, and lower LDL / HDL ratio best predicted morbidity risk, which may be related to arthritis. Unlike humans, in gorillas age and sex alone best predicted cardiac disease, and mortality risk was best predicted only by age.

Primate Biol., 7, 35–39, https://doi.org/10.5194/pb-7-35-2020, 2020<br>
In this study, we report fur-rubbing behavior of brown titi monkeys, Plecturocebus brunneus, using chewed leaves from (Fabaceae) and Piper tuberculatum (Piperaceae). These reports were obtained during systematic monitoring of titi monkeys from May until December 2019 (218 h) in an urban fragment forest in the Brazilian Amazon. Both plant species contain chemical substances in their leaves that potentially repel ectoparasites. The genus Piper is known for its repelling action due to the presence of amides, alkaloids and benzoic acid. The presence of dogs, cats and human settlements may contribute to an increase of ectoparasites, making a potential self-medication function of fur rubbing in this primate species plausible.

Sleep is the longest and most continuous behavioral phase in the 24 h cycle of mammals. However, selection of postures, substrates, and tree parts during sleep has not been adequately explored, as well as their evolutionary consequences. The present study investigates postural behavior, substrate, and tree part use during sleep in three howler species (A. palliata, A. macconnelli, and A. caraya) in Nicaragua, French Guiana, and Argentina. All three species were consistent in the use of a crouch.
