RESUMO

There are five different primate species inhabiting widely distinct ecoregions in Argentina. Each of them faces various threats in terms of conservation and conflicts that hamper their ability to coexist with human populations. We present here some of the drivers known to be the causes of conflicts between humans and primates in the southernmost area of distribution of Latin American primates. We focus our synthesis on two of the biggest sources of conflict: the effects of different anthropogenic disturbances, and human misconceptions concerning the role of primates in the ecosystem. In each section, we briefly characterize the conflicts worldwide and then provide specific cases and examples from Argentina. In the last part of the manuscript, we further describe some ongoing national and regional educational, research, and conservation approaches to mitigate those effects.

RESUMO

Capuchins are omnivorous neotropical primates that can survive in urban forests by supplementing their diet with human foods. However, few studies have analyzed the impact of these resources on their diet diversity and feeding seasonality. We aimed to assess the patterns of foraging, feeding, and diet diversity of urban capuchins (Sapajus sp.) that live in a tiny urban forest in Foz do Iguaçu, Brazil, where humans frequently feed them. We predicted that forest degradation and human foods could decrease diet diversity, though capuchins may, conversely, reduce their selectivity and expand their food repertoire. We followed the animals from dawn to dusk between May 2018 and April 2019 to list and quantify the species and items consumed. We used diversity indexes and cluster analysis to understand similarities and differences in the diet composition over the study period. We recorded 58 plant species (being 14 exotics) consumed by the monkeys, and nonconventional items, with low diet diversity overall. The diet consisted mainly of plants (69.8%), animal matter (20.6%), and processed foods (9.5%). Capuchins consumed more food from the anthropic environment (57.5%) than from the forest (42.4%), while their food from the forest included more invertebrates (47.8%) than fruits (40%). The cluster analysis showed two main groups of feeding months, in accordance with the seasons of high and low food production in local forests. Monkeys did not vary the frequencies of foraging or feeding between seasons, probably due to the omnipresent availability of human foods. Despite the high consumption of human foods, capuchins responded to the seasonality of the forest, expanding their feeding diversity in the drier period. Future studies should analyze the correspondence between food consumption and local phenology, as well as the potential role of capuchins as seed dispersers in this depauperate community.

RESUMO

Studies of urban monkeys provide important insights into the behavioral flexibility of primate species. We studied two provisioned groups of capuchin monkeys that inhabit a small forest fragment in the city of Goiânia, Brazil. One of the groups was dominant and had priority of access to both native and provisioned resources. Anthropic resources were available in two relatively small areas within this forest, but varied in their quality. We hypothesized that intergroup dominance and the seasonality of native resources would have different impacts on the foraging strategies and use of space by the two study groups. Data on the location of the members of the two groups, their behavior, and consumption of different food items were collected during five dry season and five rainy season months. The members of the dominant group spent more time in the provisioned area where anthropic food was less costly to obtain and consumed more provisioned fruit and vegetables than the members of the subordinate group. The differences between groups were exacerbated during the dry season, when sources of native fruit were less abundant. The results of the present study illustrate how capuchins may respond to the variation in proximate factors, such as intergroup dominance and seasonality. These factors were determinants to the variation in the diet and the use of space observed between the two study groups.

RESUMO

In primates, urine washing (UW) is a behavior in which individuals intentionally deposit urine on their bodies. Social and nonsocial hypotheses have been proposed to explain the adaptive function of this behavior. For capuchins, different functions have been assigned for UW, suggesting it as a flexible behavior, but studies have been mainly in captivity. However, no investigations have been performed in urban environments, where these animals can modify their behavior. Our goal was to study UW in a semi-provisioned group of an introduced unknown robust capuchin species (Sapajus sp.) living in a tiny urban fragment in Foz do Iguaçu, Brazil, where they have contact with humans. We assessed the influence of social (sexual, agonistic, and anointing behaviors) and environmental (temperature, relative air humidity, height of the monkeys in the trees, number of people present in the fragment, and human-monkey interactions) variables, the influence of behavior before and after UW, and the influence of sex-age classes, on the frequency of UW. We observed 75 records of UW in 300 h of observations, where urine was mostly deposited on hands and passed on to feet (95%). There were no significant differences in the frequency of the behavior between sex-age classes nor in the behaviors before and after UW. Around 50% of UW took place in the late morning and we found no correlation between UW and temperature, relative air humidity, nor the heights of the monkeys in the trees. However, we found a significant association between UW and the daily number of people in the fragment, but not between UW and human-monkey interactions, anointing, agonisms, and sexual behavior. Our study increases the scope of UW flexibility by identifying the presence of visitors affecting the occurrence of this behavior. We discussed different possibilities through which people could influence the capuchins to display UW.

RESUMO

Constant changes in natural environments impose challenges to wild animal populations, especially those that depend on social life. We gathered data on the activity budget and social interactions of a capuchin monkey (Sapajus sp.) group of 17 individuals confined to an urban green area receiving human food supplementation. We observed the capuchins between 7:00 am and 5:00 pm, three days a month, between January 2012 and June 2013 (total of 530 hours of direct observations). We collected 15,208 behavioral records through instantaneous scan sampling and 2,538 events of social interaction in an adapted version of the “all occurrences” method. Activity budget of capuchins was dominated by traveling (42%) and foraging (38%), followed by feeding (10%), social interactions (5%), resting (4%), and others (2%). Except for feeding, the time spent on other activities varied across sex-age classes. Social interactions of capuchins were dominated by affiliative interactions (80%), mainly social play, followed by agonistic (11%) and cooperative (10%) interactions. Sexual interactions were rare (0.4%) and often involved juveniles (45% of the events). Juveniles performed most of the social interactions, followed by the alpha male, and were the main receptors of grooming, food sharing, and agonism. On the other hand, they were the main group involved in allocarrying of infants. Grooming between females and from them to alpha male was infrequent. However, grooming of the alpha male towards the adult females was frequent. We interpreted the deviations in the activity budget and social interactions of the urban capuchins as effects of human food supplementation and restriction on dispersal, illustrating the behavioral ability of capuchin monkeys to adjust their activity in human-altered environments.(AU)

RESUMO

BACKGROUND: World migration shifts emphasize the necessity of framing health behavior in the context of life course. Mexican-born households in the U.S. disproportionally experience food insecurity, a condition associated with poor health. Food assistance programs may not be accessible to immigrants, suggesting food provisioning strategies may play a critical protective role. OBJECTIVE: To explore life course and ecological system influences on food provisioning among low-income, Mexican-born mothers in the U.S. to identify target influences and behaviors for interventions. METHODS: Life Course Perspective and Ecological Systems Theory guided this qualitative study. INCLUSION CRITERIA: 1) woman born in Mexico, 2) ≤10 years in U.S., 3) residing in one of two New York State counties, 4) at least one child ≤5 years old, and 5) <200% of the federal poverty line. Participants completed two semi-structured interviews, including a participant-driven photo elicitation interview, in English or Spanish, and a food insecurity assessment. Thematic content analysis identified emergent themes. RESULTS: Five themes emerged that were related to three key life course concepts: social context in Mexico (food insecurity experiences, agrarian experiences, and traditional foods and flavors), transitions (motherhood), and turning points (health events). All themes related to mothers' overall priority of providing home-cooked meals, and demonstrated life course influences shaping food provisioning values and strategies. CONCLUSION: Considering life course experiences is important to creating effective, multi-level approaches to reduce food insecurity among Mexican-born families in the northeastern U.S. Programs should have a particular emphasis on new or soon-to-be mothers and should include improved access to affordable in-season produce or gardening opportunities, peer-led food provisioning programs, and food and nutrition assistance programs.

RESUMO

UNLABELLED: REMISE OF THE STUDY: Wild edible plants (WEPs) have an important cultural and economic role in human population worldwide. Human impacts are quickly converting natural habitats in agricultural, cattle ranch, and urbanized lands, putting native species on peril of risk of extinction, including some WEPs. Moreover, global climate changes also can pose another threat to species persistency. Here, we established conservation priorities for the Cerrado, a neotropical region in South America with high levels of plant endemism and vulnerability, aiming to assure long-term persistency of 16 most important WEPs. We evaluated these conservation priorities using a conservation biogeography framework using ecological patterns and process at a biogeographical scale to deal with species conservation features. METHODS: We built ecological niche models for 16 WEPs from Cerrado in the neotropics using climate models for preindustrial, past (Last Glacial Maximum) and future (year 2080) time periods to establish climatically stable areas through time, finding refugias for these WEPs. We used a spatial prioritization algorithm based on the spatial pattern of irreplaceability across the neotropics, aiming to ensure the persistence of at least 25% of range size in climatically stable areas for each WEP, using agricultural models as constraints. KEY RESULTS: The Southeast Cerrado was the most biotically stable and irreplaceable region for the WEPs compared with other areas across the neotropics. CONCLUSIONS: Our findings strongly suggest that the Southeast Cerrado should be considered a conservation priority, with new protected areas to be sustainably managed and restored, to guarantee the supply of cultural and ecosystem services provided from the Cerrado's WEPs.

RESUMO

Capuchin monkeys, Sapajus Kerr, 1792, are known for their flexible behavior, including tool use, and their ability to survive in urban forests. We observed capuchin juveniles using wood as hammer and anvil and different materials as sponges (four tool-use events) in two geographically distinct urban populations in Brazil, in 2012: two in Goiânia, Central Brazil and two in Foz do Iguaçu, Southern Brazil. In Goiânia, a male used a detached tree branch as a hammer and a buttress root as an anvil to pound a seed of Terminalia Linnaeus. Another male used a small branch with leaves as a dipping tool to access water inside a tree trunk hole. In Foz do Iguaçu, the capuchins used a small branch and a piece of bread to obtain water by dipping them into tree trunk holes. This latter event might be interpreted as a case of self-control, with a familiar food item used as a tool to reach a resource that is difficult to access otherwise. Our observations contribute to the knowledge on the tool-kit of capuchins and we propose that these urban populations should be conserved for scientific evaluations of behavioral flexibility in non-human primates.(AU)

RESUMO

This paper explores the expected outcome of maternal nutritional "buffering," namely that children's diets will be more adequate than mothers' diets under conditions of food scarcity. Data on Amazonian mothers and their children, household demography and economics and direct, weighed measures of household food availability and dietary intakes of mother-child pairs were collected from 51 households to address the following research questions: (1) is there evidence of food scarcity in this setting?; (2) are there differences in energy and protein adequacy between children and their mothers?; and, (3) which individual and household-level factors are associated with these mother-child differences in energy and protein adequacy? In this context of food scarcity, we found that the majority of children had more adequate energy (p < 0.001) and protein (p < 0.001) intakes than their mothers. Multivariate OLS regression models showed that of the individual-level factors, child age and height-for-age were negatively associated with maternal-child energy and protein inequalities while maternal reproductive status (lactation) was positively associated with energy inequality. While there were no gender differences in dietary adequacy among children, boys had a larger advantage over their mothers in terms of protein adequacy than girls. Household food availability was related to maternal-child energy and protein inequalities in a curvilinear fashion with the lowest inequalities found in households with extremely low food availability and those with adequate food resources. This is the first study to quantify maternal-child dietary inequalities in a setting of food scarcity and demonstrates the importance of the household context and individual characteristics in understanding the degree to which mothers protect their children from resource scarcity.
