“…To evaluate our first prediction (P1), we used the square root of body mass multiplied by head‐body length divided by 3,537 to calculate each individual's body surface area (BSA) following Wang and Hihara (). We then divided BSA by the individual's body mass to obtain the surface area/body mass ratio (Retamal & Mascie‐Tayor, ). Given that males and females of the two CAT sites did not differ in their body measurements (see results), we pooled the data for the BBFS and ASSU marmoset population.…”

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.

Abstract: This study suggests that WHZ and SA/mass variation may be influenced by ecogeographical factors in this Chilean sample.
