N1 - Funding Information:
We thank Dr. Geraldo Baracuhy for permission to conduct the research at the Baracuhy Biological Field Station. Data on body weights and body measurements from a small number of common marmosets trapped at the Atlantic Forest site of N?sia Floresta were provided by Leslie Digby. This study was funded by a grant from CAPES (PVE no. 88881.064998/2014-01), two Ph.D. grants from CAPES awarded to M. F. C. De la Fuente and F. Abreu, and grants from the National Council for Scientific and Technological Development (CNPq) no. 480364/2011-7, 409511/2013-7, and 310847/2015-0, and the Research Support Foundation of the state of Rio Grande do Norte (FAPERN) no. 010/2009. Leonardo da Silva Chaves provided assistance in creating Figure. We thank Mrs. Patricia P. S. Macedo director of FLONA Nisia Floresta and Mr. Mauro dos Anjos director of FLONA A?u for the logistical support during the data collection. PAG wishes to thank Sara and Jenni for their support and inspiration. We acknowledge the insightful comments of two external reviewers and the review editor that have helped to strengthen our manuscript.

N2 - Understanding the set of factors that promote and constrain a species’ ability to exploit ecologically distinct habitats is central for addressing questions of intraspecific variability in behavior and morphology. In this study, we compared newly collected data with published data on body measurements, group size and composition, daily path length, home range, and reproductive output in wild common marmosets naturally inhabiting two contrasting environments in northeastern Brazil: the Atlantic Forest (AF), which is characterized by high biodiversity and reduced seasonality in food availability and the Caatinga (CAT), which is characterized by a severe hot and dry season lasting from 5 to 11 months, drought-resistant plant species, and reduced primary productivity. Despite marked differences in ecological conditions, CAT marmosets and AF marmosets differed minimally in daily path length, home range, reproductive output, and infant survivorship. CAT marmosets were found to live in smaller groups containing fewer adult females than AF marmosets, and also were characterized by a greater surface area to body mass ratio, a trait that may represent an adaptation to the hot and dry conditions of the Caatinga. We propose that in conjunction with body mass reduction, minor adjustments in behavior, the exploitation of cacti as a source of water and nutrients, and access to exudates as a dependable year-round food resource, common marmosets successfully used the same adaptive pattern to maintain high reproductive output and infant survivorship in exploiting these two ecologically distinct environments.
