Gastrointestinal parasite diversity of South American camelids (Artiodactyla: Camelidae): First review throughout the native range of distribution.

In South America inhabit an endemic group of ungulates adapted to extreme environments: the South American camelids (SAC), a key component of the Andean biocultural heritage. Until today, SAC are the most important factor of Andean economies and social and ritual life. SAC include two wild species, the guanaco (Lama guanicoe) and the vicuña (Vicugna vicugna), and two domestic species, the llama (Lama glama) and the alpaca (Vicugna pacos). Endoparasitosis are one of the most common diseases in SAC, and have great economic and health relevance. Despite this, there is a lack of knowledge on this concern. The main objective of this work was to conduct the first systematic review of the diversity of gastrointestinal parasites of SAC throughout the entire native range of distribution and to identify several gaps in knowledge. The PRISMA protocol was performed and a total of 101 documents were summarized. At least 36 parasitic helminths and five Eimeria spp. were registered. This work highlights the need for a greater number of works to know with more certainty the parasitic fauna of camelids in the past and present, in order to achieve predictions that allow proper management of camelids for their future conservation. Furthermore, concerted research efforts are needed to understand the biology, epidemiology, diagnosis and distribution of the parasitosis of SAC along the entire distribution range to guide conservation decisions.

Camelid husbandry in the Atacama Desert? A stable isotope study of camelid bone collagen and textiles from the Lluta and Camarones Valleys, northern Chile.

Management of camelids in the coastal valleys of the Andes has generated much debate in recent years. Zooarchaeological and isotopic studies have demonstrated that in the coastal valleys of northern and southern Peru there were locally maintained camelid herds. Because of the hyperarid conditions of the northern coast of Chile, this region has been assumed to be unsuitable for the raising of camelids. In this study we report stable carbon and nitrogen isotopic compositions of camelid bone collagen and textiles made from camelid fiber from Late Intermediate Period (LIP) and Late Horizon (LH) occupations in northern Chilean river valleys. The camelid bone collagen isotopic compositions are consistent with these animals originating in the highlands, although there is a significant difference in the camelids dating to the LIP and LH, possibly because of changes made to distribution and exchange networks by the Inca in the LH. There were no differences between the isotopic compositions of the camelid fibers sampled from textiles in the LIP and LH, suggesting that either the production of camelid fiber was unchanged by the Inca or the changes that were made do not present visible isotopic evidence. Several camelid fiber samples from both the LIP and LH present very high δ13C and δ15N values, comparable to human hair samples from one site (Huancarane) in the Camarones Valley. These data suggest that people in the northern valleys of Chile may have kept small numbers of animals specifically for fiber production. Overall, however, the vast majority of the textile samples have isotopic compositions that are consistent with an origin in the highlands. These data suggest that the hyperarid coastal river valleys of northern Chile did not support substantial camelid herds as has been interpreted for northern Peru.

Procurement of camelid fiber in the hyperarid Atacama Desert coast: Insights from stable isotopes

Pastoralism and camelid management are traditionally attributed to the sociopolitical, economic and cosmovision of Andean populations, rather than to lowland hunter gatherer societies, living on the Pacific coast where camelid hunting is considered a marginal activity, and husbandry is a difficult enterprise given the hyper-arid conditions of lowland terrestrial ecosystems. Contrary to this interpretative historical view, our stable isotope analyses applied to 48 camelid fiber samples, suggests this highly valued camelid byproduct was obtained from camelids sustained on lomas vegetation formations during the Archaic (ca. 6500-4000 cal yr BP), Formative (ca. 4000-1500 cal yr BP) and Late periods (ca. 660-480 cal yr BP).

New Bioarchaeological Evidence and Radiocarbon Dates from the Lambayeque/Sicán Culture Camelids from the El Brujo Complex (Northern Coast of Peru): Implications for Funerary and Herd Management Practices

ABSTRACT Pastoralism and camelid management have been essential to all aspects of pre-Hispanic Andean societies. Here, we present zooarchaeological and isotopic data on domestic camelid remains from Huaca Cao Viejo (El Brujo archaeological complex) on the northern coast of Peru, and dated to the Lambayeque/Sicán period—to characterise their biological age, diet, life history, possible geographic origin and ritual use. Domestic camelids, representing a wide range of biological ages and a high rate of polydactyly, were found as burial offerings in direct association with human funerary bundles (fardos). Direct AMS dates indicated that camelids were buried over a short period of time (AD 1022–1176) confirming the Lambayeque presence in the Chicama Valley during the first half of the Late Intermediate Period. Stable isotopic analyses were carried out on both bone collagen and hair keratin, including incremental analysis. A considerable variability in δ13C values at both the intra-individual and the intra-group level and a large contribution of C4 resources to diet are shown. This clearly supports local management and camelids originating from various herds. Zooarchaeological and isotopic evidences suggest diversity in herding practices and suggest the importance of the herds in fulfilling the transportation demands for trade in goods.

Patterns of camelid management in Wari Empire reconstructed using multiple stable isotope analysis: evidence from Castillo de Huarmey, northern coast of Peru

Camelid management was a major part of the Wari Empire’s (ca. ad 600–1050) economy; however, it is uncertain whether camelid husbandry was centrally regulated or locally managed. To address this problem, we applied combined isotope ratio analyses (δ13C, δ15N, δ18O, 87Sr/86Sr, and 20nPb/204Pb) to camelid remains from Castillo de Huarmey, a Wari administrative center along the northern Peruvian coast. Results support a mostly local herding scenario, but Sr isotopes indicate that at least three animals were non-local and most likely came from the highlands. Compared to data from two contemporary Wari sites, Cerro Baul and Conchopata, bimodal distribution of δ13C values suggest that regardless of the distinctive geographical and ecological location of these sites, two distinct foddering strategies were practiced, based on only C3 plant diet, or intermixed C3/C4 plants diet. Our data support a dimorphic husbandry model with some herds engaged in grazing on the maize stubble and some herds operating outside arable areas, possibly indicative of short-distance seasonal transhumance. The presence of non-local animals at Castillo de Huarmey underscores the site’s importance with respect to developed trade networks between the coast and the highlands.

Variation in camelid δ13C and δ15N values in relation to geography and climate: Holocene patterns and archaeological implications in central western Argentina

Camelids are among the largest wild and domestic faunas in South America and represent one of the most important taxa to pre-hispanic South America human populations. Stable isotope data from these animals play an important role in improving our understanding of human paleodiet, past human-animal interactions, Holocene environmental change, and modern camelid management. This paper presents δ13C and δ15N values taken from 91 camelid specimens distributed across western Argentina between 30° and 37° S. These samples come from three desert environments (Andean, Patagonia, and Monte) and include both modern and prehistoric samples. Camelid δ13C values range between −20.3‰ and −10.7‰, while δ15N values vary between 2‰ and 10.2‰. Mean isotope values differ by environmental context, with significant difference in δ13C and δ15N between Patagonian and Monte or Andean deserts. Camelid isotope values also vary with latitude, altitude and longitude, though differences in δ15N are weak, and these geographic differences are tied to climatic variables such as annual mean temperature, annual precipitation, and season of precipitation. When comparing camelid δ13C values from Central-western Argentina with those from Northwest Argentina and Patagonia, we see a latitudinal trend of decreasing δ13C values, with the most negative values occurring in southern Patagonia and the most positive values in Northwest Argentina. Variation in camelid stable isotope values and their association with particular environmental contexts shows their value as a geographic marker and possibly as a paleoecological proxy. These results highlight the need to consider the geographic origin of camelid isotope values when using them to reconstruct human diet.

Isótopos estables en camélidos del período tardío del noroeste de Argentina (NOA): estrategias de uso y manejo de rebaños

The stable isotope (δ13C y δ15N) results on appendicular camelid bones (n=28) from three sites in Northwestern Argentina are presented: Esquina de Huajra and Pucara de Volcan in the Quebrada de Humahuaca (Jujuy province) together with Tolombon in the Calchaqui Valley (Salta province) were occupied during both the Late and Incaic period. We discuss procurement and redistribution of both wild and domestic ungulates. The isotopic results allow us to broaden our present understanding of the complex camelid management system implemented by Andean societies in pre-Colonial times.

Early Horizon camelid management practices in the Nepeña Valley, north-central coast of Peru

South American camelids (llamas and alpacas) were of great economic, social and ritual significance in the pre-Hispanic Andes. Although these animals are largely limited to high-altitude (>3500 masl) pastures, it has been hypothesised that camelids were also raised at lower altitudes in the arid coastal river valleys. Previous isotopic studies of Early Intermediate Period (c. 200 BC–AD 600) and Middle Horizon (c. AD 600–1100) camelids support this argument. Here, we utilise carbon and nitrogen isotopic analyses of camelid bone collagen from the Early Horizon (c. 800–200 BC) sites of Caylán and Huambacho on the north-central coast of Peru to examine the management of these animals during the first millennium BC. Most of the camelid isotopic compositions are consistent with the acquisition of animals that were part of caravans, moving between the coast and the highlands. A small number of the animals may have been raised on the coast, suggesting that the practice of coastal camelid husbandry was in the experimental phase during the Early Horizon before growing into a more established practice in the Early Intermediate Period. These results echo zooarchaeological studies from the region that have revealed a paucity of camelid remains in refuse deposits prior to 800 BC, followed by an increase in abundance after 450 BC.

Small scale camelid husbandry on the north coast of Peru (Virú Valley): Insight from stable isotope analysis

This study presents carbon and nitrogen isotopic compositions for bone collagen and serially sampled hair from a large collection of South American camelids from two Early Intermediate Period (c. 200 BC to AD 800) sites (Huaca Gallinazo and Huaca Santa Clara) in the Virú Valley (north coast of Peru). The isotopic compositions of these camelids are consistent with plant isotopic compositions from coastal and low altitude settings, but not from high altitude environments, suggesting that at least some of these animals were raised locally. We present several methodological approaches with respect to the treatment of isotopic data from archaeological contexts, outlining quantitative approaches that can provide considerable insight into isotopic variation (within groups, within individuals, between groups, between individuals), as well as temporal variation in isotopic compositions in incrementally growing tissues. We contend that focusing explicitly on variation in animal life histories has the greatest potential with respect to better understanding human–animal interactions in the past. The results demonstrate a large amount of isotopic variability among individuals and an inconsistent amount of within-individual variation, with no consistent shift in the diet leading up to the time of death for a group of animals from a single ritual event. This result suggests that camelid husbandry in the Virú Valley was a small-scale activity, with groups of camelids being managed by families or other small social units. Animals were likely kept primarily in close association to human habitation sites and provided with a diverse array of fodder. These prolonged interactions, occurring at a limited spatial scale, would have allowed a high degree of mutual familiarity to develop between humans and animals. Isotopic compositions for late Middle Horizon (c. AD 1100) sacrificed llamas from Huaca Santa Clara are consistent with Early Intermediate Period camelids, suggesting temporal stability in this small-scale camelid management strategy on the coast, which was fundamentally different from camelid herding in the pastures of the Andean highlands. Isotopic analysis of prehistoric livestock has great potential with respect to better understanding animal husbandry practices and human–animal interactions in the broadest sense because the data provide insight into the ways in which animals lived, rather than the manner in which they died. The variation-centered methodologies outlined in this paper provide a framework with which to approach some of these issues, highlighting the significance of understanding variability in livestock life histories.

Bone pathologies in a modern collection of guanaco (Lama guanicoe): Contributions to the interpretation of bone lesions in archeological contexts

Research on animal paleopathology has significantly grown in the field of zooarchaeology during the last years. Usually bone lesions have been associated to specific activities carried out by animals. However, the etiology and prevalence of many bone abnormalities are still uncertain due to the scarcity of studies in modern reference collections. The aim of this study is to determine the postcranial skeletal lesions that characterize a population of wild camelids and to differentiate bone lesions related to human management of camelids. For this purpose, we analyze the health status of a modern collection of guanaco by recording a series of indicators and its manifestation in different anatomical units. The osteological sample comprises 54 guanacos from Cinco Chañares, San Antonio department, Rio Negro province, Argentina. The frequency of lesions by anatomical unit, sex, and age were studied in order to generate parameters for comparison with other samples of contemporary camelids and with zooarchaeological record. The analyzed sample is characterized by infectious, traumatic, degenerative and congenital abnormalities in low prevalence. The most common pathologies were degenerative origin. These were significantly more frequent among senile adults, and were differentiated of the ones registered among domestic camelids.

Camelid handling in the meridional Andes during the first millennium AD: a preliminary approach using stable isotopes

AbstractStable isotope analysis has been used in archaeology to answer a variety of questions. In general, the study of human palaeodiets has been the main subject. Studies of past animal feeding behaviour have not been considered extensively in South America. In this paper we discuss the interpretation of the δ 13C values in camelid bone specimens on the basis of published and new data from the southern Andes (northwestern Argentina). The temporal frame is mainly focused in the first millennium AD (part of the local Formative Period – 400 BC to 600 AD – as well as the Regional Integration Period at 600–1000 AD, and the Late Period at 1000–1500 AD) which for this area implies a time of great social changes. Samples from modern Camelidae family were used to compare with those from archaeological sites, interpreting two different patterns that can be associated with distinctive animal feeding strategies. We suggest that these strategies can be associated with human management rather than free‐range camelid feeding behaviour. Thus stable isotopes become an innovative strategy to segregate domestic from wild camelids, complementing those results achieved by osteometric and statistical analyses. Moreover, they allow for camelid management interpretation in three different localities of the area from the above‐mentioned different periods. Copyright © 2009 John Wiley & Sons, Ltd.
