Impact of Botfly Parasitism on the Behavior of Mantled Howler Monkeys
Parasitism, a widespread nutrient acquisition strategy among animals, results from a long evolutionary history where one species derives its metabolic needs from another. Parasites can significantly reduce host fitness, affecting reproduction, growth, and survivability. Vertebrate hosts exhibit defensive strategies against parasites, including “sickness behaviors” such as lethargy and self‐grooming to remove ectoparasites. In addition, social ani…
The Network Structure of Social Play
Social networks formed via play interactions offer a powerful framework for investigating the social dynamics of animals and the functions of play behavior. Using this framework in mantled howler monkeys ( Alouatta palliata ), we examined whether social play might fulfil some of the affiliative and bonding functions typically addressed to allogrooming. We analyzed play networks in seven groups of mantled howler monkeys (89 individuals), analyzing…
Mantled howler monkeys (Alouatta palliata) show no preferential hand use in two self-directed behaviors
Bot fly parasitism in mantled howler monkeys ( Alouatta palliata )
Parasitism is a strong selective pressure, and its study is crucial for predicting the persistence of host species. Mantled howler monkeys are infected by the larvae of the bot fly Cuterebra baeri . This parasitosis produces myiasis and may have negative impacts on host health, although systematic information on the dynamics of this host‐parasite relationship is very limited. Currently, all available information on infection patterns of C. baeri …
Forest maturity has a stronger influence on the prevalence of spider monkeys than howler monkeys in an anthropogenically impacted rainforest landscape
The transformation and depletion of primary forest over the past few decades have placed almost half of the world’s primate species under the threat of extinction. Developing any successful conservation program for primates requires distribution and demography data, as well as an understanding of the relationships between these factors and their habitat. Between March and June 2010 and 2011 we collected data on the presence and demographic parame…
Validation of a Fecal T3 Metabolite Assay for Measuring Energetics in Wild Golden Snub-Nosed Monkeys (Rhinopithecus roxellana)
How Do Hunter-Gatherer Children Learn Social and Gender Norms? A Meta-Ethnographic Review
Forager societies tend to value egalitarianism, cooperative autonomy, and sharing. Furthermore, foragers exhibit a strong gendered division of labor. However, few studies have employed a cross-cultural approach to understand how forager children learn social and gender norms. To address this gap, we perform a meta-ethnography, which allows for the systematic extraction, synthesis, and comparison of quantitative and qualitative publications. In al…
Savanna chimpanzees adjust sleeping nest architecture in response to local weather conditions
OBJECTIVES: Great ape nests are hypothesized to aid safe, secure sleep via providing thermoregulation or protection from predators and vectors. We aimed to describe and investigate variation in chimpanzee nest architecture across two populations in response to local weather conditions. MATERIALS AND METHODS: We experimentally tested whether nests provide insulation by measuring heat loss within and outside nests, and took detailed measurements of…
How Do Hunter-Gatherer Children Learn Subsistence Skills
Hunting and gathering is, evolutionarily, the defining subsistence strategy of our species. Studying how children learn foraging skills can, therefore, provide us with key data to test theories about the evolution of human life history, cognition, and social behavior. Modern foragers, with their vast cultural and environmental diversity, have mostly been studied individually. However, cross-cultural studies allow us to extrapolate forager-wide tr…
Which is the appropriate scale to assess the impact of landscape spatial configuration on the diet and behavior of spider monkeys
Understanding the response of species to changes in landscape configuration is required to design adequate management and conservation strategies. Yet, the most appropriate spatial scale (i.e., landscape size) to assess the response of species to changes in landscape configuration (so-called "scale of effect") is largely unknown. In this paper, we assess the impact of landscape forest cover, forest fragmentation, edge density, and inter-patch iso…
Limited genetic diversity in the critically endangered Mexican howler monkey (Alouatta palliata mexicana) in the Selva Zoque, Mexico
Behavioral and physiological responses to subgroup size and number of people in howler monkeys inhabiting a forest fragment used for nature‐based tourism
Animals' responses to potentially threatening factors can provide important information for their conservation. Group size and human presence are potentially threatening factors to primates inhabiting small reserves used for recreation. We tested these hypotheses by evaluating behavioral and physiological responses in two groups of mantled howler monkeys (Alouatta palliata mexicana) at the "Centro Ecológico y Recreativo El Zapotal", a recreationa…
Travel Time Predicts Fecal Glucocorticoid Levels in Free-Ranging Howlers (Alouatta palliata)
Parasitic infections of three Mexican howler monkey groups (Alouatta palliata mexicana) living in forest fragments in Mexico
Seasonal Variations in the Diet and Feeding Effort of Two Groups of Howlers in Different Sized Forest Fragments
Differences in diet and activity pattern between two groups of Alouatta palliata associated with the availability of big trees and fruit of top food taxa
The threat that forest fragmentation and habitat loss presents for several Alouatta taxa requires us to determine the key elements that may promote the persistence of howler monkeys in forest fragments and to evaluate how changes in the availability of these elements may affect their future conservation prospects. In this study we analyzed the relationship between the availability of both big trees of top food taxa (BTTFT) (diameter at breast hei…
Demography, life history and migrations in a Mexican mantled howler group in a rainforest fragment
This paper represents the results of a long‐term study (1996–2003) on the demographic changes over time of a Mexican mantled howler ( Alouatta palliata mexicana ) group in a rainforest fragment (40 ha) in Los Tuxtlas, Mexico, with a follow‐up census 3 years later (2006). In addition to demographic and life history parameters, we describe six dispersal events. Our results suggest that this group has been expanding during the study period, growing …
Glucocorticoid levels in free ranging resident mantled howlers
A growing amount of data shows that a preference for passive‐nonaggressive over active‐aggressive problem solving is associated with higher levels of glucocorticoids (GC). For mantled howlers, the arrival of an adult male in a new group is a potential source of psychological stress for both resident males and females. Resident mantled howler males take an active stand and aggressively repel the entrance of solitary males, while females take a pas…
Diet and activity pattern of howler monkeys ( Alouatta palliata ) in Los Tuxtlas, Mexico
Accelerated deforestation is causing the rapid loss and fragmentation of primary habitat for primates. Although the genus Alouatta is one of the most studied primate taxa under these circumstances, some results are contradictory and responses of howlers to habitat fragmentation are not yet clear. In this paper, we conduct a cross‐study of the available researches on mantled howlers ( Alouatta palliata ) in forest fragments in Los Tuxtlas, Mexico,…
Biogeographical and floristic predictors of the presence and abundance of mantled howlers (Alouatta palliata mexicana) in rainforest fragments at Los Tuxtlas, Mexico
This research focuses on identifying the principal habitat characteristics that influence the presence and abundance of mantled howlers in forest fragments. We provide information on the demography of several fragmented Alouatta palliata mexicana subpopulations at Los Tuxtlas, Mexico, and relate this to the biogeographical and floristic characteristics of the forest fragments inhabited. The most important habitat characteristics related to the pr…
