Cooperative relationships among male primates are emerging as an important aspect of primate social behavior. What remains unclear is the extent to which male associations with coresident males vary within species, and what social and demographic factors drive these associations. This information provides an important contribution to our understanding of how cooperative relationships play an adaptive role in the evolution of male social and reproductive strategies. To examine the nature of male associations and the influence of social and demographic factors, including rank and age, we collected 1751 h of focal behavioral data on adult males in two large multimale–multifemale groups of mantled howlers (Alouatta palliata) at La Pacifica, Costa Rica. Both groups inhabited upland forest area, were of similar size and sex ratio, and exhibited strongly linear male hierarchies. Based on observed spatial associations within 3 m proximity, dyadic patterns varied from strongly preferred to strongly avoided associations that were largely consistent among dyads over the study period. In contrast to reports from other mantled howler study sites, neither rank nor age differences among males predicted whether dyads spent any time in proximity to one another, nor the amount of time in proximity. However, higher-ranked males within dyads were more likely to maintain close proximity than their lower-ranked counterparts. Our results provide important data on the nature of male associations within mantled howler groups with linear dominance relationships, and are suggestive of the adaptive value of cooperative relationships.

Abstract Habitat structure may have a significant influence on the occurrence, abundance, and activity patterns of forest mammals. However, anthropogenic habitat disturbance changes habitat structure, which may alter those patterns of activity. We assessed occurrence, relative abundance, and activity patterns of Dromiciops gliroides, an arboreal marsupial endemic to the temperate rainforests of southern South America, contrasting four forest conditions at a regional scale: old-growth, second-growth, and logged forests, and abandoned exotic plantations. We conducted a camera-trap assessment in two consecutive austral summers across most of the Chilean range of D. gliroides, and compared habitat structure along a disturbance gradient. All structural features assessed differed among forest conditions. Dromiciops gliroides was present in all forest conditions, but its abundance decreased and activity got narrower as disturbance increased, being significantly lower in the exotic plantations. Activity patterns were variable among forest conditions and months, and were significantly more restricted temporally at exotic plantations. Although D. gliroides is tolerant to habitat disturbance, we show that structural alteration results in lower abundances and narrower activity patterns.

Abstract Anthropogenic habitat disturbances can dramatically alter ecological community interactions, including host-pathogen dynamics. Recent work has highlighted the potential for habitat disturbances to alter host-associated microbial communities, but the associations between anthropogenic disturbance, host microbiomes, and pathogens are unresolved. Amphibian skin microbial communities are particularly responsive to factors like temperature, physiochemistry, pathogen infection, and environmental microbial reservoirs. Through a field survey on wild populations of Acris crepitans (Hylidae) and Lithobates catesbeianus (Ranidae), we assessed effects of habitat disturbance on environmental bacterial resevoirs, Batrachochytrium dendrobatidis (Bd) infection, and skin microbiome composition. We found higher measures of microbiome dispersion (a measure of community stability) in A. crepitans from more disturbed ponds, supporting the hypothesis that disturbance increases stochasticity in biological communties. We also found that habitat disturbance limited microbiome similarity between locations for both species, suggesting less bacterial exchange in more disturbed areas. Higher disturbance was associated with lower Bd prevalence for A. crepitans, which could signify suboptimal microclimates for Bd in disturbed habitats. In this system we use microbiome dispersion as a metric of population health. Combined, our findings show that reduced microbiome stability stemming from habitat disturbance could compromise population health, even in the absence of pathogenic infection.
