Data from: Variable intergroup encounters: What drives neutral and intolerant encounters in blue monkeys?
<p>In group-living animals, between-group relations are often revealed during intergroup encounters, which may be intolerant (competitive), affiliative (cooperative), or neutral. Our study investigated factors that predict different encounter types in blue monkeys, where intolerant encounters predominate but neutral encounters also occur. Using data from 9 groups monitored over 24 months in equatorial forest, we first examined whether the availability of fruit, a preferred and important food, predicted monthly <strong><em>encounter rates</em> </strong>for individual groups. We then examined how fruit availability and time of day influenced the odds that <strong><em>individual encounters</em> </strong>were intolerant vs. neutral. For a subset of encounters between study groups with well-known histories, we examined the effects of additional social and location factors, which included group size, the proportion of females with infants, the time elapsed since the opposing groups had split from each other in the past years, and the encounter's location on edge-centre axes for both groups. Finally, we examined how ecological and social factors predicted individual <em><strong>group behaviour</strong> </em>(aggressive, fleeing, neutral) during encounters. The variables we examined included encounter location, group size, group size differential, time since the two groups split from each other, fruit availability, and time of day. These investigations required 3 data sets (one for each italicized item in this abstract, namely rates, encounters, and records of group behavior).</p>

Dispersal patterns in black howler monkeys (Alouatta pigra): Integrating multi-year demographic and molecular data
<p>Dispersal is a fundamental process in the functioning of animal societies as it regulates the degree to which closely related individuals are spatially concentrated. A species' dispersal pattern can be complex as it emerges from individuals' decisions shaped by the cost-benefit tradeoffs associated with either remaining in the natal group or dispersing. Given the potential complexity, combining long-term demographic information with molecular data can provide important insights into dispersal patterns of a species. Based on a 15-year study that integrates multi-year demographic data on six groups with longitudinal and cross-sectional genetic sampling of 20 groups (N=169 individuals, N=21 polymorphic microsatellite loci), we describe the various dispersal strategies of male and female black howler monkeys (<i>Alouatta pigra</i>) inhabiting Palenque National Park, Mexico. Genetically confirmed dispersal events (N=21 of 59 males; N=6 of 65 females), together with spatial autocorrelation analyses revealed that the dispersal pattern of black howlers is bisexual with strong sex-biases in both dispersal rate (males disperse more often than females) and dispersal distance (females disperse farther than males). Observational and genetic data confirm that both males and females can successfully immigrate into established groups, as well as form new groups with other dispersing individuals. Additionally, both males and females may disperse singly, as well as in pairs, and both may also disperse secondarily. Overall, our findings suggest multiple dispersal trajectories for black howler males and females, and longer multi-year studies are needed to unravel which demographic, ecological, and social factors underlie individuals' decisions about whether to disperse and which dispersal options to take.</p>
Data from: The birth hour of mammals: insights from intra-specific variation in wild blue monkeys
<p>While most mammals show birth hour peaks at times of the 24-hour cycle when they are less active, there are exceptions to this general pattern. Such exceptions have been little explored, but may clarify evolutionary reasons for the diel timing of births. We investigated intraspecific variation in birth hour in wild blue monkeys (<i>Cercopithecus mitis stuhlmanni</i>), a diurnal primate, to identify factors that differentiated daytime vs. nighttime births. Behavioral and life history data from 14 groups over 14 years revealed that 4% of 484 births occurred during the day. Probability of daytime birth varied with mother's age, peaking at 15.7 years. Births whose annual timing deviated most from the population's peak birth months were five times more likely to occur during daytime than those that deviated less. There was no evidence that mother's rank or infant sex influenced birth hour, and mixed evidence that daytime births were more probable in larger groups. Survivorship did not differ significantly for infants born during the day vs. night. Prime-aged mothers may be able to handle the consequences of an unusual birth hour more successfully than mothers with less experience or those weakened by age. Daytime birth may be more advantageous in the off-season because nights are colder at that time of year. These findings are consistent with hypotheses relating birth hour to the risk of losing social protection in group-living animals, but are not consistent with those emphasizing risk of conspecific harassment. Patterns of within-species variation can help in evaluating evolutionary hypotheses for non-random birth hour.</p>

Seed traits of seed within spider monkey, howler monkey feces, and dung beetles' dung balls
<p>These data files contain seed traits from three sources, 1) seed traits from "Seeds of Amazonian Plants", 2) Royal Botanic Gardens Kew Seed Information Database, and 3) seeds dissected from field collections of primate feces and dung balls from dung beetles. The dataset was used in the article published in Biotropica entitled "<em>Seed size and pubescence facilitate secondary dispersal by dung beetles</em>". The data mostly describes seed traits of morphospecies within the feces of brown-headed spider monkeys (<em>Ateles fusciceps</em>) and mantled howler monkeys (<em>Alouatta palliata</em>). Traits included in the data set are size, surface, length, width, shape, color, and dispersal by mammals. </p>
Focal vs. faecal: Seasonal variation in the diet of wild vervet monkeys from observational and DNA metabarcoding data
<p>1. Assessing the diet of wild animals reveals valuable information about their ecology and trophic relationships that may help elucidate dynamic interactions in ecosystems and forecast responses to environmental changes.</p> <p>2. Advances in molecular biology provide valuable research tools in this field. However, comparative empirical research is still required to highlight strengths and potential biases of different approaches. Therefore, this study compares environmental DNA and observational methods for the same study population and sampling duration.</p> <p>3. We employed DNA metabarcoding assays targeting plant and arthropod diet items in 823 faecal samples collected over 12 months in a wild population of an omnivorous primate, the vervet monkey (<em>Chlorocebus pygerythrus</em>). DNA metabarcoding data were subsequently compared to direct observations.</p> <p>4. We observed the same seasonal patterns of plant consumption with both methods, however, DNA metabarcoding showed considerably greater taxonomic coverage and resolution compared to observations, mostly due to the construction of a local plant DNA database. We found a strong effect of season on variation in plant consumption largely shaped by the dry and wet seasons. The seasonal effect on arthropod consumption was weaker but feeding on arthropods was more frequent in spring and summer, showing overall that vervets adapt their diet according to available resources. The DNA metabarcoding assay outperformed also direct observations of arthropod consumption in both taxonomic coverage and resolution.</p> <p>5. Combining traditional techniques and DNA metabarcoding data can therefore not only provide enhanced assessments of complex diets or reveal trophic interactions to the benefit of wildlife conservationists and managers but also opens new perspectives for behavioural ecologists studying whether diet variation in social species is induced by environmental differences or might reflect selective foraging behaviours.</p>
Data from: The role of non-natural foods in the nutritional strategies of monkeys in a human-modified mosaic landscape
<p>Many tropical animals inhabit mosaic landscapes including human-modified habitat. In such landscapes, animals commonly adjust feeding behavior, and may incorporate non-natural foods. These behavioral shifts can influence consumers' nutritional states, with implications for population persistence. However, few studies have addressed the nutritional role of non-natural food. We examined nutritional ecology of wild blue monkeys to understand how dietary habits related to non-natural foods might support population persistence in a mosaic landscape. We documented prevalence and nutritional composition of non-natural foods in monkey diets to assess how habitat use influenced their consumption and their contribution to nutritional strategies. While most energy and macronutrients came from natural foods, subjects focused non-natural feeding activity on five exotic plants and averaged about a third of daily calories from non-natural foods. Most non-natural food calories came from non-structural carbohydrates and least from protein. Consumption of non-natural foods related to time in human-modified habitats, which two groups used non-randomly. Non-natural and natural foods were similar in nutrients, and the amount of non-natural food consumed drove variation in nutritional strategy. When more daily calories came from non-natural foods, females consumed a higher ratio of non-protein energy to protein (NPE:P). Females also prioritized protein while allowing NPE:P to vary, increasing NPE while capitalizing on non-natural foods. Overall, these tropical mammals achieved a similar nutrient balance regardless of their intake of non-natural foods. Forest and forest-adjacent areas with non-natural vegetation may provide adequate nutrient access for consumers, and thus contribute to wildlife conservation in mosaic tropical landscapes.</p>

Data from: Female mate choice in wild Kenyan blue monkeys (Cercopithecus mitis)
<p>Female mate choice may drive sexual selection, but discerning whether female behaviors reflect the free expression of choice or responses to constraints can be difficult. We investigated the efficacy of female choice in wild blue monkeys using 10 years of behavioral and paternity data (2002-2011) encompassing 178 male-female dyads and 63 infants. Although blue monkeys live modally in one-male polygynous groups, where male-biased intersexual power is expected, females can access multiple potential mates during seasonal male influxes and occasional intergroup encounters. Additionally, extra-group males sire offspring. We examined the unsolicited proceptive behavior that females directed to males (corrected for male availability) to determine (1) if blue monkey females express mate choice by preferentially soliciting sexual interactions with certain males, (2) which males females prefer, and (3) if observed female mate preferences are successful in influencing paternity and infant survival. The two datasets included here allowed us to answer these questions. The first dataset provides information on the degree of preference a female in her conceptive period exhibited for each male that was present, the status of each male (resident or non-resident), and whether the female's most preferred male sired her offspring. The second dataset provides information on whether a female's parity, rank, or familiarity with her resident male influenced the likelihood of siring her offspring with her most preferred male (or with the resident male) and whether an infant was more likely to survive if sired by the male its mother most preferred.</p>
Monkey V1/V2 neuronal population response to drifting gratings with varying orientation and contrast
<p>Correlated variability in the visual cortex is modulated by stimulus properties. The stimulus dependence of correlated variability impacts stimulus coding and is indicative of circuit structure. An affine model combining a multiplicative factor and an additive offset has been proposed to explain how correlated variability in primary visual cortex (V1) depends on stimulus orientations. However, whether the affine model could be extended to explain modulations by other stimulus variables or variability shared between two brain areas is unknown. Motivated by a simple neural circuit mechanism, we modified the affine model to better explain the contrast-dependence of neural variability shared within either primary or secondary visual cortex (V1 or V2) as well as the orientation-dependence of neural variability shared between V1 and V2. Our results bridge neural circuit mechanisms and statistical models, and provide a parsimonious explanation for the stimulus-dependence of correlated variability within and between visual areas.</p>
Data from: Individual differences in sociocognitive traits in semi-free-ranging rhesus monkeys (Macaca mulatta)
<p>Characterizing individual differences in cognition is crucial for understanding the evolution of cognition as well as to test the biological consequences of different cognitive traits. Here, we harnessed the strengths of a uniquely large, naturally-living primate population at the Cayo Santiago Biological Field Station to characterized individual differences in rhesus monkey performance across two social cognitive tasks. A total of <em>n</em> = 204 semi-free-ranging adult rhesus monkeys participated in a data collection procedure, where we aimed to test individuals on both tasks at two time-points that were one year apart. In the <em>socioemotional responses task,</em> we assessed monkeys' attention to conspecific photographs with neutral versus negative emotional expressions. We found that monkeys showed overall declines in interest in conspecific photographs with age, but relative increases in attention to threat stimuli specifically, and further that these responses exhibited long-term stability across repeated testing. In the <em>gaze following task</em> we assessed monkeys' propensity to co-orient with an experimenter. Here, we found no evidence for age-related change in responses, and responses showed only limited repeatability over time. Finally, we found some evidence for common individual variation for performance across the tasks: monkeys that showed greater interest in conspecific photographs were more likely to follow a human's gaze. These results show how studies of comparative cognitive development and aging can provide insights into the evolution of cognition, and identify core primate social cognitive traits that may be related across and within individuals.</p>
Data from: Feeding sites promoting wildlife-related tourism might highly expose the endangered Yunnan snub-nosed monkey (Rhinopithecus bieti) to parasite transmission. DOI: 10.1038/s41598-021-95166-5
<p>An increasing number of studies have found that the implementation of feeding sites for wildlife-related tourism can affect animal health, behaviour and reproduction. Feeding sites can favour high densities, home range overlap, greater sedentary behaviour and increased interspecific contacts, all of which might promote parasite transmission. In the Yunnan snub-nosed monkey (Rhinopithecus bieti), human interventions via provisioning monkeys at specific feeding sites have led to the sub-structuring of a group into genetically differentiated sub-groups. The fed subgroup is located near human hamlets and interacts with domesticated animals. Using high-throughput sequencing, we investigated Entamoeba species diversity in a local host assemblage strongly influenced by provisioning for wildlife-related tourism. We identified 13 Entamoeba species or lineages in faeces of Yunnan snub-nosed monkeys, humans and domesticated animals (including pigs, cattle, and domestic chicken). In Yunnan snub-nosed monkeys, Entamoeba prevalence and OTU richness were higher in the fed than in the wild subgroup. Entamoeba polecki was found in monkeys, pigs and humans, suggesting that this parasite might circulates between the wild and domestic components of this local social–ecological system. The highest proportion of faeces positive for Entamoeba in monkeys geographically coincided with the presence of livestock and humans. These elements suggest that feeding sites might indirectly play a role on parasite transmission in the Yunnan snub-nosed monkey. The implementation of such sites should carefully consider the risk of creating hotspots of disease transmission, which should be prevented by maintaining a buffer zone between monkeys and livestock/humans. Regular screenings for pathogens in fed subgroup are necessary to monitor transmission risk in order to balance the economic development of human communities dependent on wildlife-related tourism, and the conservation of the endangered Yunnan snub-nosed monkey.</p>
High plasticity in marmoset monkey vocal development from infancy to adulthood
<p>The vocal behavior of human infants undergoes dramatic changes across their first year, while becoming increasingly speech-like. Surprisingly, vocal development in nonhuman primates has been assumed to be largely predetermined and completed within the first postnatal months. Contradicting this assumption, we found a dichotomy between the development of call features and vocal sequences in marmoset monkeys suggestive of a role for experience. While changes in call features were related to physical maturation, sequences of and transitions between calls remained flexible until adulthood. As in humans, marmoset vocal behavior developed in stages correlated with motor and social development stages. These findings are evidence for a prolonged phase of plasticity during marmoset vocal development, a crucial primate evolutionary preadaptation for the emergence of vocal learning and speech.</p>
