“…They also play important roles in many aspects of human societies (culture, religion, livelihood), and are key for our understanding of human evolution, biology and behavior [7]. Nevertheless, many primates are threatened with extinction (63%) [8], with the primary threats being habitat loss, pet-trade, and bushmeat hunting [7,9]. Mexico is the northernmost distribution for New World primates with two of their native species Alouatta pigra and Ateles geoffroyi categorized as 'Endangered' by the IUCN [10].…”

Several studies suggest that 63% of primate species are currently threatened due to deforestation, pet-trade, and bushmeat hunting. Successful primate conservation strategies require effective educational programs capable of enhancing critical system-thinking and responsible behavior towards these species. Arts-based conservation education can simultaneously foster cognitive and emotional processes. In this paper, we evaluate an artsbased educational program focused on the conservation of black howler monkeys (Alouatta pigra). Our goals were to determine (1) whether children's knowledge changed with our educational techniques, (2) if there was a particular educational technique that better improved the children's learning, and (3) the children's emotional feedback regarding the whole program. A total of 229 children from communities located in primate-habitat areas, both inside and outside protected areas, participated in the study. Different educational techniques were tested (storytelling, theater and shadow puppets), contrasted with a control group, and evaluated through an analysis of drawings. Our results showed that children's knowledge increase with each art-based technique, with storytelling being the most effective for children's learning. Specific drawings indicators also revealed the increase of children's knowledge and a decrease of misconceptions between pre and post evaluations. Finally, a satisfaction survey about the program showed a high positive feedback. The study highlights the value of designing multidisciplinary projects, where arts-based education program (grounded in scientific information) has shown to be a successful way to communicate animal knowledge and promote conservation.

“…Plecturocebus (=Callicebus) ornatus (Gray 1866) is a primate species that typically inhabits tropical forests (Carretero-Pinzon and Defler, 2016), and is categorized as Vulnerable according to the IUCN Red List of Species, because of the continuous decline of its habitat due to deforestation (Cotton et al, 2016). This species is endemic of the Easter Plains of Colombia, mainly the Meta department (Defler, 2010).…”

Plecturocebus ornatus is an endemic vulnerable species due to its population decline and its restricted range within the Eastern Plains of Colombia. This region is affected by deforestation as a result of legal and illegal economic activities. The aim of this work was to analyze the presence and abundance of P. ornatus during a period of urban and livestock production expansion (1986-2019) in Villavicencio, Colombia. This municipality is the most affected by land-use changes associated with regional economic development and represents 3.4 % of P. ornatus distribution’s area. The analysis was performed using satellite images Landsat 4 and 8, with V-Late in ArcGIS 10.5 to describe landscape structure, and P. ornatus occurrence records, obtained through field observations and the Global Biological Information Facility. Densities were calculated for each fragment based on total individuals observed by transect. A generalized lineal model was used to evaluate the effects of patch-scale, landscape-scale and other variables on P. ornatus abundance. By 1986 the rural and peri-urban areas of Villavicencio were already a transformed landscape. During the analyzed period, landscape was predominantly made up of disconnected linear fragments with a secondary humid forest cover. Around 82.1 % of the fragments with P. ornatus records are threatened by urbanization and only 50 % are in protected areas. Densities varied from 0.00 to 7.26 ind/ha (0.00–726.82 ind/km2). Abundance of P. ornatus was highly influenced by landscape-scale variables related with landscape connectivity, as well as fragment area and number of other primate species. Therefore, the implementation of restoration measures that increase landscape connectivity and habitat availability is proposed, as well as more control over environmental land-use planning, to contribute to the conservation of P. ornatus in urban areas.

“…Platyrrhines, referred as New World monkeys (NWM), naturally occurring in central and southern American tropical and subtropical regions and catarrhines (Cercopithecoidea and Hominoidea), referred as Old World monkeys (OWM), coming from tropical, subtropical, and temperate regions of Asia and Africa 2 . Many primate species are endangered 3 and they must be protected. The conservation of threatened species is a complex and demanding process consisting of elaborated breeding programs and providing of habitat sanctuaries in captive or semi-captive centres, e.g.…”

Bifidobacteria, which commonly inhabit the primate gut, are beneficial contributors to host wellbeing. Anatomical differences and natural habitat allow an arrangement of primates into two main parvorders; New World monkeys (NWM) and Old World monkeys (OWM). The number of newly described bifidobacterial species is clearly elevated in NWM. This corresponds to our finding that bifidobacteria were the dominant group of cultivated gut anaerobes in NWM, while their numbers halved in OWM and were often replaced by Clostridiaceae with sarcina morphology. We examined an extended MALDI-TOF MS database as a potential identification tool for rapid screening of bifidobacterial distribution in captive primates. Bifidobacterial isolates of NWM were assigned mainly to species of primate origin, while OWM possessed typically multi-host bifidobacteria. Moreover, bifidobacterial counts reflected the feed specialization of captive primates decreasing from frugivore-insectivores, gummivore-insectivores, frugivore-folivores to frugivore-omnivores. Amplicon sequencing analysis supported this trend with regards to the inverse ratio of Actinobacteria and Firmicutes. In addition, a significantly higher diversity of the bacterial population in OWM was found. The evolution specialization of primates seems to be responsible for Bifidobacterium abundance and species occurrence. Balanced microbiota of captive primates could be supported by optimized prebiotic and probiotic stimulation based on the primate host.
