Mean age at menarche and climate variables on a global scale
We propose that later ages at menarche in countries with high fertility may be a life-history strategy developed in response to climatic conditions that have resulted in higher immunological load. In these conditions, females may prioritize growth rather than reproduction. Shifts in climate and global population growth may change the future biological landscape of age at menarche

Ecological niche modeling of the genus Papio
OBJECTIVE: Ecological niche modeling (ENM) has been used to assess how abiotic variables influence species distributions and diversity. Baboons are broadly distributed throughout Africa, yet the degree of climatic specialization is largely unexplored for individual taxa. Also, the influence of climate on baboon phylogenetic divergence is unknown. In this study, we constructed ENMs to investigate how niches vary across Papio species to understand …

Effects of Environmental Stress on Primate Populations
Environmental stress on primate populations can take many forms. Abiotic factors, such as temperature and precipitation, may directly influence the behavior of primates owing to physiological demands of thermoregulation or through indirect influences on vegetation that primates rely on for food. These effects can also scale up to the macro scale, impacting primate distributions and evolution. Primates also encounter stress during interactions wit…
Behavioral thermoregulation in Lemur catta: The significance of sunning and huddling behaviors
Regulation of body temperature poses significant problems for organisms that inhabit environments with extreme and seasonally fluctuating ambient temperatures. To help alleviate the energetic costs of autonomic responses, these organisms often thermoregulate through behavioral mechanisms. Among primates, lemurs in Madagascar experience uncharacteristically seasonal and unpredictable climates relative to other primate-rich regions. Malagasy primat…
Resource seasonality and reproduction predict fission–fusion dynamics in black‐and‐white ruffed lemurs ( Varecia variegata )
Ruffed lemurs (genus Varecia) are often described as having a flexible social organization, such that both cohesive (low fission-fusion dynamics) and fluid (high fission-fusion dynamics) grouping patterns have been observed. In ruffed lemur communities with high fission-fusion dynamics, group members vary in their temporal and spatial dispersion throughout a communally defended territory. These patterns have been likened to those observed in seve…
Transparency, usability, and reproducibility: Guiding principles for improving comparative databases using primates as examples
Recent decades have seen rapid development of new analytical methods to investigate patterns of interspecific variation. Yet these cutting‐edge statistical analyses often rely on data of questionable origin, varying accuracy, and weak comparability, which seem to have reduced the reproducibility of studies. It is time to improve the transparency of comparative data while also making these improved data more widely available. We, the authors, met …

Did Trichromatic Color Vision and Red Hair Color Coevolve in Primates
Reddish pelage and red hair ornaments have evolved many times, independently, during primate evolution. It is generally assumed that these red‐coat phenotypes, like red skin phenotypes, play a role in sociosexual signaling and, thus evolved in tandem with conspecific color vision. This study examines the phylogenetic distribution of color vision and pelage coloration across the primate order to ask: (1) did red pelage and trichromacy coevolve; or…
Understanding primate communities: Recent developments and future directions
In 1999, the edited volume Primate Communities presented several studies that examined broad-scale patterns of primate diversity. Similar studies were being conducted on nonprimate taxa; advances in data availability and statistical approaches were allowing scientists to investigate a variety of new questions and to reexamine classical questions in novel ways. While such studies on nonprimate taxa have continued at a steady pace, they have only c…
Testing Bergmann's rule and the resource seasonality hypothesis in Malagasy primates using GIS‐based climate data
We tested four major hypotheses on the ecological aspects of body mass variation in extant Malagasy strepsirrhines: thermoregulation, resource seasonality/scarcity, resource quality, and primary productivity. These biogeographic hypotheses focus on the ecological aspects of body mass variation, largely ignoring the role of phylogeny for explaining body mass variation within lineages. We tested the independent effects of climate and resource‐relat…
Does geography or ecology best explain ‘cultural’ variation among chimpanzee communities
Species co‐occurrence patterns and dietary resource competition in primates
Diamond (Assembly of species communities. In: Cody ML, Diamond JM, editors. Ecology and evolution of communities. Cambridge: Belknap. p 342–444 ( 1975 )) argued that interspecific competition between species occupying similar niches results in a nonrandom pattern of species distributions. In particular, some species pairs may never be found in the same community due to competitive exclusion. Rigorous analytical methods have been developed to inve…

Environmental and geographic correlates of the taxonomic structure of primate communities
Previous research has shown that both environmental and historical factors influence the taxonomic structure of animal communities; yet, the relative importance of these effects is not known for primates. Environmental characteristics shape the possible niches in a community, providing suitable habitats for some species and not others. Therefore, communities found in similar environments should display similar species compositions. Additionally, …

Examining the extinction risk of specialized folivores: A comparative study of Colobine monkeys
Species extinctions are nonrandom with some taxa appearing to possess traits that increase their extinction risk. In this study, eight predictors of extinction risk were used as independent variables to predict the IUCN category of a subfamily of specialized folivorous primates, the Colobinae. All data were transformed into phylogenetically independent contrasts and were analyzed using bivariate regressions, multiple regression, and a maximum lik…
