“…Although many authors have argued that the detection of plant items (e.g., fruits and leaves) have played a primordial role in the origin of primates' trichromacy (Caine & Mundy, 2000; Dominy & Lucas, 2001; Dominy et al, 2003; Lucas et al, 2003; Osorio & Vorobyev, 1996; Perini et al, 2009; Smith et al, 2003; Sumner & Mollon, 2000, 2003b; Melin et al, 2017a, 2017b), and since the selective pressures responsible for the maintenance of a trait throughout the evolutionary time are not necessarily the same responsible for its origin (Fernandez & Morris, 2007; Griffiths, 1996), here we advocate that the selection of trichromacy for predator detection might have worked as a preadaptation for the consumption of conspicuous fruits, leaves, and flowers (Dominy & Lucas, 2001; Hogan et al, 2016; Perini et al, 2009; Sumner & Mollon, 2003b).…”

Primates' predators, such as carnivore mammals, usually rely on camouflage to increase proximity to prey and start a predatory attempt. Camouflage depends not only on the color pattern presented by a predator's pelage but also on the background scene in which the hunting takes place. Another factor that influences camouflage effectiveness is prey's color vision since a given camouflage strategy might not work for all visual phenotypes. Still, little research has been made on the effect of primate visual phenotype on predator detection. Here, we investigate the effects of natural pelages, background scenarios, visual phenotypes, and detection distances on predator detection. We used photographs of taxidermized carnivores (ocelots, cougars, and lesser grisons) as detection stimuli, taken in three different natural scenarios (forest, savanna, and grassland), and at two viewing distances (near and far). On a touchscreen monitor, sets of four images (only one containing a hidden animal) were randomly presented to 39 human males (19 dichromats and 20 trichromats). We found that trichromats, when compared to dichromats, present a lower latency and a higher accuracy of carnivore detection for some conditions tested. We also found that pelage color, background scenario, and detection distance interact to influence the effectiveness of camouflage. Our results suggest that trichromacy might be even more advantageous for carnivore detection than thought before, since it facilitates detection of mammals with diverse pelage colorations, in environments with different phytophysiognomies, and at longer distances. We also propose that the higher rates of dichromacy found in modern human societies could have resulted from a relaxation in predation.

“…Similarly, many of the families of plants that were only identified using the trnL method–Annonaceae, Burseraceae, Caricaceae, Cordiaceae (Boraginaceae), Passifloraceae, and Rhamnaceae–are plants that are known to be part of the white-faced capuchin diet, either at this site or other sites in Costa Rica, but are infrequently consumed [ 39 – 41 ]. Other plant families identified by only the rbcL method (Araceae, Cyclanthaceae, and Ulmaceae) or the trnL method (Acanthaceae, Bromeliaceae, and Marantaceae) include plant species that are consumed by white-faced capuchins [ 39 , 40 , 42 ], but the flower or leaves are consumed, so they were not recorded as part of the fruit diet in this study. Both the rbcL method and the trnL method identified plant families that have not yet been recorded as part of the white-faced capuchin diet, but are present in this area of Costa Rica, and so may be rarely consumed by this group of white-faced capuchins.…”

trnL outperforms rbcL as a DNA metabarcoding marker when compared with the observed plant component of the diet of wild white-faced capuchins (Cebus capucinus, Primates)

DNA metabarcoding is a powerful tool for assessing the diets of wild animals, but there is no clear consensus on which proposed plant barcoding marker is most suitable for dietary analysis. This study compares two DNA plant barcoding markers that are commonly used for dietary analyses from degraded DNA, rbcL and trnL, to detailed dietary observations of wild white-faced capuchins (Cebus capucinus). Observational dietary data and fecal samples (n = 170) were collected for one year from a group of individually recognizable monkeys at La Suerte Biological Field Station, Costa Rica. DNA was extracted and portions of the rbcL and trnL chloroplast were amplified and sequenced on the Illumina MiSeq platform. Sequences were analyzed using obitools. Of the two barcoding markers tested, trnL yielded greater numbers of sequences with equal sequencing effort, higher resolution taxonomic identifications (albeit with a larger reference database), and identified a greater number of families also found in the observed diet. There was no relationship between observed capuchin feeding behavior and dietary composition based on either sequence occurrence or relative abundance of sequences using rbcL as a marker. However, dietary composition based on the relative abundance of trnL sequences was significantly positively associated with the observed percentage of feeding and foraging time capuchins’ spent on each plant species. Additionally, in 35% of cases, the relative abundance of trnL sequences assigned to particular plant families in fecal samples was highly positively correlated with time spent consuming plants from those same families. Our results indicate that trnL is a more robust DNA metabarcoding marker for plant dietary analysis and may potentially be used to quantitatively assess differences in diet within or between species.

Research on non-human primates in the endangered tropical dry forest of Sector Santa Rosa (SSR), Área de Conservación Guanacaste (ACG), was launched in 1983 and is now one of the longest running studies of primates globally. Such continuous study provides a rare opportunity to ask questions that are only answerable through decades-long monitoring of these long-lived monkeys. In turn, the mounting data generated by long-term study, including knowledge of lifetime reproductive success, familial relatedness, comprehensive behavioral and dietary repertoires, and patterns of inter-and intra-annual variation in forest productivity, provide diverse opportunities to researchers, and facilitate studies that are of shorter duration. Here, we review some of the contributions of our longitudinal research on white-faced capuchins and Geoffroy's spider monkeys, together with newer studies on mantled howler monkeys. We begin by synthesizing findings from our research on demography, dispersal, social relationships, and reproduction. These life history and social traits interact with their
