Preliminary isotopic assessment of weaning in bonobos shows evidence for extended nursing, sibling competition and invested first‐time mothers
Although considered a hallmark in early ontogeny, weaning from breastmilk is difficult to monitor in wild primates and weaning ages remain unknown for wild bonobos ( Pan Paniscus ). Here, we calculated inter‐birth intervals from demographic data and measured the isotopic offsets (Δ 15 N and Δ 13 C) between mother ( n = 17) and offspring ( n = 28) fecal sample pairs ( n = 131, total n = 246) in the LuiKotale bonobos to assess nutritional weaning f…
Diet along the eastern Silk Roads
A skew in poo
Feces are a treasure trove in the study of animal behavior and ecology. Stable carbon and nitrogen isotope analysis allows to assess the dietary niches of elusive primate species and primate breastfeeding behavior. However, some fecal isotope data may unwillingly be biased toward the isotope ratios of undigested plant matter, requiring more consistent sample preparation protocols. We assess the impact of this potential data skew in 114 fecal samp…
A bioavailable strontium isoscape of Angola with implications for the archaeology of the transatlantic slave trade
The region of present-day Angola was one of the main areas from which millions of enslaved Africans were abducted and forced to migrate to the Americas during the transatlantic slave trade. Strontium isotope (87Sr/86Sr) analysis is a useful tool in reconstructing large-scale human movements across geologically distinct landscapes in archaeological and forensic contexts. However, the absence of environmental 87Sr/86Sr reference data from Angola hi…
A multi-isotope approach to reconstructing human residential mobility and diet during the Late Intermediate Period (1000–1450 CE) in highland Ancash, Peru
Seasonality and interindividual variation in mandrill feeding ecology revealed by stable isotope analyses of hair and blood
Mandrills are large‐bodied terrestrial forest primates living in particularly large social groups of several hundred individuals. Following these groups in the wild to assess differences in diet over time as well as among individuals is demanding. We here use isotope analyses in blood and hair obtained during repeated captures of 43 identified free‐ranging mandrills ( Mandrillus sphinx ) from Southern Gabon, to test how dietary variation relates …
Maize and dietary change in early Peruvian civilization
The Late Preceramic Period (3000–1700 BCE) and Initial Period (1700–800 BCE) in Peru was a time of emergent social complexity as illustrated by the construction of ceremonial architecture and permanent settlements. A long-standing debate centers on the nature of the subsistence economies that supported this incipient complexity. Though some scholars consider maize to have been an agricultural staple at this time, a growing body of archaeological …
How isotopic signatures relate to meat consumption in wild chimpanzees
Stable isotope variation in savanna chimpanzees ( Pan troglodytes verus ) indicate avoidance of energetic challenges through dietary compensation at the limits of the range
Objectives Food scarcity is proposed to be a limitation to chimpanzees at the limits of their range; however, such a constraint has never been investigated in this context. We investigated patterns of δ 13 C and δ 15 N variation along a latitudinal gradient at the northwestern West African chimpanzee ( Pan troglodytes verus ) range limit with the expectation that isotope ratios of chimpanzees at the range limit will indicate different dietary str…
Reconstructing temporal variation in great ape and other primate diets
Stable isotope analysis of carbon and nitrogen in hair provides a versatile tool for reconstructing feeding behavior in elusive primate species. Particularly in great apes, researchers can sample long hair completely non-invasively from nests, allowing the investigation of inter- and intra-individual dietary variation. Given its incremental growth pattern, hair records temporal shifts in diet over long periods and allows one to reconstruct season…
Advances in primate stable isotope ecology—Achievements and future prospects
Stable isotope biogeochemistry has been used to investigate foraging ecology in non-human primates for nearly 30 years. Whereas early studies focused on diet, more recently, isotopic analysis has been used to address a diversity of ecological questions ranging from niche partitioning to nutritional status to variability in life history traits. With this increasing array of applications, stable isotope analysis stands to make major contributions t…
Who is who matters—The effects of pseudoreplication in stable isotope analyses
Stable isotope analysis in free-ranging primates is a promising new avenue in reconstructing feeding niches and temporal dietary variation. Particularly, the large sample sizes obtained from non-invasively collected hair and fecal samples from nests of great apes offer great potential. However, analyzing repeated observations of the same individuals without controlling for potential differences among them means to "pseudoreplicate" and can lead t…

There's No Place Like Home’—no Isotopic Evidence for Mobility at the Early Bronze Age Cemetery of Singen, Germany
The Early Bronze Age necropolis of Singen (Hohentwiel), located near Lake Constance, represents a population from a period of technological transition in southwestern Germany. The site contains several graves with metal artefacts that originated in other parts of Central and Western Europe, and therefore these could be interpreted as being the graves of non‐local individuals. The purpose of this study was to investigate this possibility through t…
Multi‐isotopic analysis reveals individual mobility and diet at the early iron age monumental tumulus of magdalenenberg, germany
For the Early Iron Age western Hallstatt culture, which includes the site of Magdalenenberg in southwest Germany, it has been proposed that people were mobile and maintained far reaching social and trading networks throughout Europe. We tested this hypothesis by analyzing multiple isotopes (strontium, oxygen, sulfur, carbon, and nitrogen) of the preserved skeletons from the Magdalenenberg elite cemetery to determine diets and to look for evidence…
