Comparative Analysis of Fecal Microbiome Composition in Zoo‐Housed Colobines
This study investigated the interplay between dietary macronutrient composition, browse provisioning frequency, and host phylogeny in shaping the gut microbiome of zoo‐housed colobine monkeys. We focused on four species ( Colobus guereza, Colobus angolensis, Trachypithecus cristatus , and Trachypithecus francoisi ) housed across 20 AZA‐accredited institutions and integrated detailed dietary records with fecal microbiome profiling. Diets were cate…
Assessing the Determinants of Platyrrhine Quadrupedal Gait Kinematics in an Ecological and Phylogenetic Framework
Laboratory studies have broadened our understanding of primate arboreal locomotor biomechanics and adaptation but are necessarily limited in species availability and substrate complexity. In this field study, we filmed the locomotion of 11 species of platyrrhines (Ecuador and Costa Rica; n = 1234 strides) and remotely measured substrate diameter and orientation. We then explored ecological and phylogenetic influences on quadrupedal kinematics in …
Oral Processing Behaviors of Golden Monkeys ( Cercopithecus mitis kandti ) From Volcanoes National Park in Rwanda
Primate foraging behaviors are influenced by a variety of factors including the physical and mechanical properties of food items. Golden monkeys ( Cercopithecus mitis kandti ) inhabiting Volcanoes National Park (VNP), Rwanda, rely heavily on mechanically challenging bamboo shoots and bamboo leaves for the bulk of their diet. We examined the oral processing behaviors of golden monkeys and predicted that bamboo shoots would be characterized by more…

Aspects of molar form and dietary proclivities of African colobines
The effects of natural substrate discontinuities on the quadrupedal gait kinematics of free‐ranging Saimiri sciureus
Wild primates encounter complex matrices of substrates that differ in size, orientation, height, and compliance, and often move on multiple, discontinuous substrates within a single bout of locomotion. Our current understanding of primate gait is limited by artificial laboratory settings in which primate quadrupedal gait has primarily been studied. This study analyzes wild Saimiri sciureus (common squirrel monkey) gait on discontinuous substrates…
Effects of substrate and phylogeny on quadrupedal gait in free‐ranging platyrrhines
OBJECTIVES: Primate diagonal sequence (DS) gaits are often argued to be an adaptation for moving and foraging in the fine-branch niche; however, existing data have come predominantly from laboratory studies that are limited in taxonomic breadth and fail to account for the structural and ecological variation of natural substrates. We test the extent to which substrate diameter and orientation influence gait sequence type and limb phase in free-ran…

Nutrient intake and balancing among female Colobus angolensis palliatus inhabiting structurally distinct forest areas
Understanding intraspecific behavioral and dietary variation is critical for assessing primate populations' abilities to persist in habitats characterized by increasing anthropogenic disturbances. While it is evident that some species exhibit considerable dietary flexibility (in terms of species-specific plant parts) in relation to habitat disturbance, it is unclear if primates are characterized by similar variation and flexibility regarding nutr…
A user's guide for the quantitative analysis of substrate characteristics and locomotor kinematics in free‐ranging primates
OBJECTIVES: Laboratory studies have yielded important insights into primate locomotor mechanics. Nevertheless, laboratory studies fail to capture the range of ecological and structural variation encountered by free-ranging primates. We present techniques for collecting kinematic data on wild primates using consumer grade high-speed cameras and demonstrate novel methods for quantifying metric variation in arboreal substrates. MATERIALS AND METHODS…
Feeding Ecology and Dietary Flexibility of Colobus angolensis palliatus in Relation to Habitat Disturbance
Humeral correlates of forelimb elevation in four West African cercopithecid monkeys
OBJECTIVES: We previously found that differing degrees of forelimb flexion, elevation, and abduction during nonlocomotor foraging activities covaried with scapular morphology among four sympatric cercopithecids. The purpose of this study is to investigate whether features of the proximal humerus are similarly related to forelimb elevation during foraging. METHODS: Our sample consists of humeri (n = 42) of adult Cercocebus atys, Cercopithecus dian…
A unique case of extra-group infant adoption in free-ranging Angola black and white colobus monkeys (Colobus angolensis palliatus)
Quantifying soluble carbohydrates in tropical leaves using a portable mid‐infrared sensor
Identifying the nutritional composition of food items has significant ramifications for primate feeding ecology, which, in turn, influences investigations of primate sociality, cognition, and conservation. The aim of our study was to analyze water soluble carbohydrate (WSC) concentrations in the leaves of trees common to the Diani Forest of Kenya. Many of these leaves are consumed by black and white colobus monkeys (Colobus angolensis palliatus).…
The role of leaf toughness on foraging efficiency in Angola black and white colobus monkeys ( Colobus angolensis palliatus )
OBJECTIVES: Examining the relationships among foraging behavior, food mechanical properties, and masticatory morphology is a bourgeoning research topic among behavioral ecologists and functional morphologists. The purpose of this study was to assess the degree to which leaf toughness influences foraging efficiency with regard to ingestion rate, masticatory investment, and masticatory rate. METHODS: Diet and feeding data were collected on adults f…
