“…The age of females varied between 4 and 20 years, and all but one female, were multiparous. No reproductive seasonality has been documented in this population (Cano‐Huertes et al, ). Following Balcells and Baró (), we classified immature individuals as infants 1 (0 to <4 months), infants 2 (4 to <9 months), infants 3 (9 to <15 months), or juveniles 1 (15 to 20 months).…”

“…From August 2013 to July 2015 we studied six adult females belonging to two groups of mantled howler monkeys that lived at La Flor de Catemaco (Los Tuxtlas, Veracruz, México; 18°26′39″ N, 95°02′57″ W). The study site and population have been previously described (e.g., Cano‐Huertes et al, ; Dias et al, ). La Flor de Catemaco is a 250‐ha ranch that includes ca.…”

“…The energetics of female reproduction seem to be an important factor in determining female leadership in group movements (Conradt, Krause, Couzin, & Roper, 2009; Sueur, Deneubourg, Petit, & Couzin, 2010), and may result from the relatively high motivation of reproductive females to find food resources, as they normally require more energy than males for reproduction (Emery Thompson, 2013; Erhart & Overdorff, 1999; Richard, Dewar, Schwartz, & Ratsirarson, 2000), a pattern also observed in non‐primate species (e.g., Equus burchelli : Fischhoff et al, 2007, Mungos mungo : Furrer, Kunc, & Manser, 2012; Suricata suricatta : Turbé, 2006). Higher motivation to reach food resources could explain why gestating and lactating females of this species tend to have higher physical condition than cycling females (Cano‐Huertes et al, 2017; Dias et al, 2017).…”

“…During gestation and lactation mantled howler monkey females increase the consumption of fats, proteins, and energy (Serio‐Silva, Hernández‐Salazar, & Rico‐Gray, 1999), and have higher glucocorticoid hormone concentrations (independently of psychosocial activation of the stress axis: Dias, Coyohua‐Fuentes, Canales‐Espinosa, Chavira‐Ramírez, & Rangel‐Negrín, 2017) than cycling females. Female energetic condition (assessed via urinary C‐peptide concentrations) does not vary significantly among reproductive stages, although gestating females tend to have higher physical condition than other females (Cano‐Huertes et al, 2017). This evidence suggests that female mantled howler monkeys meet the increased metabolic demands of gestation and lactation through diet adjustments and metabolization of energy reserves.…”

Benefits of group life depend in large part on whether animals remain cohesive, which often requires collective decisions about where and when to move. During a group movement, the leader may be considered as the individual occupying the vanguard position of the group progression, when its movement evokes following by other group members. In nondespotic societies, individuals with greater incentives to move frequently are leaders. During 15 months of observations (1,712 contact hours), we investigated two mantled howler monkey (Alouatta palliata) groups at La Flor de Catemaco (Los Tuxtlas, Mexico) to examine whether sex and female reproductive state influenced leadership likelihood in two contexts: movements toward feeding trees; movements associated with loud calls, a group‐defense behavior used by males of this genus. Females led and occupied forward positions during group movements toward feeding trees more often than adult males. Adult females led these movements more frequently when they were gestating than when they were lactating or cycling. There were no differences between sexes in the leadership of group movements associated with loud calls. Leadership by gestating females is perhaps the result of their higher nutritional/energetic needs when compared with cycling females, and of their greater mobility when compared with lactating females carrying dependent offspring. Female leadership during movements toward feeding trees may be a mechanism to optimize access to food resources in mantled howler monkeys.

“…Given that sex allocation is proximately affected by maternal physical condition (Cameron et al, ; Gutiérrez‐Adán et al, ; Rangel‐Negrín, Coyohua‐Fuentes, Canales‐Espinosa, et al, ; Ryan et al, ), we reviewed the literature to assess variation in infant sex ratio relative to maternal condition in howler monkeys. As there are very few data on the physical condition of female howler monkeys (Cano‐Huertes et al, ; Dias et al, ; Rangel‐Negrín, Coyohua‐Fuentes, Chavira‐Ramírez, Canales‐Espinosa, & Dias, ), we indexed maternal condition by annual rainfall and the potential for resource competition. In tropical forests, rainfall levels are positively correlated with habitat productivity such that where rainfall is higher, net primary productivity, plant biomass, and plant species diversity are higher (e.g., Lewis et al, ; Malhi et al, ; Quesada et al, ; Ter Steege et al, ; Toledo et al, ).…”

Objective: Frequency-dependent selection is expected to maintain infant sex ratios around parity over evolutionary time. However, over ecological time periods, infant sex ratios vary, and it has been proposed that this variation may reflect adaptive processes. In primates, there are consistent patterns of variation in infant sex ratios, although their adaptive significance remains contentious. In addition to design issues, contrasting results could have derived across primates from variation in the fitness benefits accrued through sons or daughters associated with the specific social, ecological, and demographic context of populations. Thus, different sex allocation tactics could occur within species over time and space.Methods: We reviewed the literature to describe variation in infant sex ratio in howler monkeys (genus Alouatta) and to examine whether such a variation could be associated with adaptive sex allocation. We found 26 studies that provided data for this review. These studies yielded 96 infant sex reports, corresponding to 1,477 sexed infants.Results: Infant sex ratio across howler monkey species tends to parity, but females produce more sons under high group densities and more daughters when rainfall increases.Discussion: Based on these results, as well as on information on howler monkey dispersal patterns, demography, and within-group genetic relatedness, we speculate that, depending on population growth stage, sex allocation is explained by (a) local resource enhancement, that is, more cooperative philopatric daughters are produced when populations are growing; and (b) local resource competition, that is, more dispersing sons are produced when populations are saturated. Thus, there is evidence suggestive of adaptive variation in infant sex ratios in howler monkeys. K E Y W O R D Sinfant sex ratio, competition, population growth, rainfall, sex allocation, sex ratio
