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…
Pied tamarins change their vocal behavior in response to noise levels in the largest city in the Amazon
Many animal species depend on sound to communicate with conspecifics. However, human‐generated (anthropogenic) noise may mask acoustic signals and so disrupt behavior. Animals may use various strategies to circumvent this, including shifts in the timing of vocal activity and changes to the acoustic parameters of their calls. We tested whether pied tamarins ( Saguinus bicolor ) adjust their vocal behavior in response to city noise. We predicted th…
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…
On the trail of primate scent signals
Chemosignals are mediators of social interactions in mammals, providing con‐ and hetero‐specifics with information on fixed (e.g., species, sex, group, and individual identity) and variable (e.g., social, reproductive, and health status) features of the signaler. Yet, methodological difficulties of recording and quantifying odor signals, especially in field conditions, have hampered studies of natural systems. We present the first use of the Tori…
Low genetic diversity and limited genetic structure across the range of the critically endangered Mexican howler monkey ( Alouatta palliata mexicana )
Genetic diversity provides populations with the possibility to persist in ever‐changing environments, where selective regimes change over time. Therefore, the long‐term survival of a population may be affected by its level of genetic diversity. The Mexican howler monkey ( Alouatta palliata mexicana ) is a critically endangered primate restricted to southeast Mexico. Here, we evaluate the genetic diversity and population structure of this subspeci…
Socioecological Factors Affecting Range Defensibility Among Howler Monkeys
Sexual selection and the loss of laryngeal air sacs during the evolution of speech
One noteworthy, but unexplained, aspect of the evolution of human speech is the loss of laryngeal air sacs during hominin evolution.Very little is known about the adaptive significance of this curious trait, or the selection pressures that may have driven the evolution of air sacs among primates, and their later loss in Homo.Here, I review the literature on the loss of laryngeal air sacs during the evolution of speech, and argue that sexual selec…
Non-invasive documentation of primate voice production using electroglottography
Electroglottography (EGG) is a low-cost, non-invasive method for documenting laryngeal sound production during vocalization. The EGG signal represents relative vocal fold contact area and thus delivers physiological evidence of vocal fold vibration. While the method has received much attention in human voice research over the last five decades, it has seen very little application in other mammals. Here, we give a concise overview of mammalian voc…
The coevolution of play and the cortico-cerebellar system in primates
Primates are some of the most playful animals in the natural world, yet the reason for this remains unclear. One hypothesis posits that primates are so playful because playful activity functions to help develop the sophisticated cognitive and behavioural abilities that they are also renowned for. If this hypothesis were true, then play might be expected to have coevolved with the neural substrates underlying these abilities in primates. Here, we …
Role of Emitter and Severity of Aggression Influence the Agonistic Vocalizations of Geoffroy’s Spider Monkeys (Ateles geoffroyi)
Limited genetic diversity in the critically endangered Mexican howler monkey (Alouatta palliata mexicana) in the Selva Zoque, Mexico
Travel Time Predicts Fecal Glucocorticoid Levels in Free-Ranging Howlers (Alouatta palliata)
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…
