Resource depression and garden hunting are major topics of archaeological interest, with important implications for understanding cultural and environmental change. Garden hunting is difficult to study using traditional zooarchaeological approaches, but isotopic analyses of animals may provide a marker for where and when people exploited nondomesticated animals that fed on agricultural resources. To realize the full potential of isotopic approaches for reconstructing garden hunting practices—and the impacts of agriculture on past nondomesticated animal populations more broadly—a wider range of species, encompassing many “ecological perspectives,” is needed. We use bone-collagen isotopic compositions of animals (n = 643, 23 taxa, 39 sites) associated with the Late Woodland (~AD 900−1650) in what is now southern Ontario to test hypotheses about the extent to which animals used maize, an isotopically distinctive plant central to subsistence practices of Iroquoian-speaking peoples across the region. Results show that although some taxa—particularly those that may have been hard to control—had substantial access to maize, most did not, regardless of the animal resource requirements of local populations. Our findings suggest that this isotopic approach to detecting garden hunting will be more successful when applied to smaller-scale societies.

This paper reports new data on stable carbon and nitrogen isotopes obtained from human skeletal remains found at six prehistoric sites dating between A.D. 400 and 1500 in southern Ontario. Analyses examine more closely the timing and intensity of maize adoption and the importance of animal protein in the diet, adding to earlier work in the region by the same authors (Schwarcz et al. 1985). As a result of changes in preferred methods of extracting bone collagen, a comparison of extraction methods is presented. Results indicate a gradual increase in the importance of maize in the diet over a period of approximately 600 years, from A.D. 650 to 1250, and little change in nitrogen isotope values during the same period. The results are considered within the larger temporal and geographical framework of eastern North America, drawing on stable isotope results from the published literature. Both paleobotanical and isotope data indicate marked differences in the timing and intensity of maize utilization in different regions of northeastern North America. Nitrogen isotope values decrease after around A.D. 1350, suggesting a decrease in animal protein in the diet. Stable isotope data provide one source of evidence for changes in human subsistence patterns and their interpretation relies on complementary data from sources such as the analysis of faunal and botanical remains, settlement patterns, and material culture.

Maya archaeologists have long been interested in understanding ancient diets because they provide information about broad-scale economic and societal transformations. Though paleodietary studies have primarily relied on stable carbon (δ13C) and nitrogen (δ15N) isotopic analyses of human bone collagen to document the types of food people consumed, stable sulfur (δ34S) isotope analysis can potentially provide valuable data to identify terrestrial, freshwater, or marine/coastal food sources, as well as determine human mobility and migration patterns. Here we assess applications of δ34S for investigating Maya diet and migration through stable isotope analyses of human bone collagen (δ13C, δ15N, and δ34S) from 114 individuals from 12 sites in the Eastern Maya lowlands, temporally spanning from the Late Preclassic (300 BCE—300 CE) through Colonial periods (1520–1800 CE). Results document a diet dominated by maize and other terrestrial resources, consistent with expectations for this inland region. Because δ34S values reflect local geology, our analyses also identified recent migrants to the Eastern lowlands who had non-local δ34S signatures. When combined with other indicators of mobility (e.g., strontium isotopes), sulfur isotopic data provide a powerful tool to investigate movement across a person’s lifespan. This study represents the largest examination of archaeological human δ34S isotope values for the Maya lowlands and provides a foundation for novel insights into both subsistence practices and migration.

Abstract: Sampling wild animal populations using non-invasive techniques is advised when dealing with threatened species. Hair samples provide ecological information like species and individual identification. However, hair trapping is scarcely used in otters, due to their aquatic habits. Most studies are with captive individuals, so there is the need to test non-invasive hair trapping methods in otters in the wild. The aim of this study was to develop a simple and cost-effective method to collect hair from otter species in a non-invasive way. The study was carried out in the Paranapanema River, São Paulo State, Brazil, with the Neotropical otter (Lontra longicaudis Olfers, 1818), a protected species. Hair traps (wooden sticks and tree roots with adhesive tape or wax bands) were set during six nights on river banks, otter trails and scent-marking sites. Traps were baited with otter fresh spraints from other river locations. From the 23 traps, 10 (43.7%) were successful in collecting otter hairs, mostly guard-hair. The sticks were much more efficient than the roots at capturing otter hair (70.6.% vs. 0%) as well as adhesive tape when compared to wax (71.4% vs. 0%). Method simplicity and efficiency suggest that it can be a cost-effective way for collecting otter hairs without the need for capturing individuals. This method can be used for: assessment of local otter distribution; collecting otter hair samples for sex and individual identification (by molecular analysis), trophic ecology (by isotopic analyses), ecotoxicology (by contamination analysis) or behaviour ecology (by hormonal and stress levels analysis). More trapping campaigns should be implemented to further test the method's efficiency.

Cortical bone samples were collected from marsupial and eutherian herbivores at five field sites along a 1275-km south–north transect from temperate coastal to arid interior South Australia in order to address variability in stable carbon isotope composition. Collection sites were located along the eastern border of the state. Mean annual rainfall along the transect ranges from 700–800 mm at coastal Mount Gambier to 150–175 mm at Cordillo Downs in the north-east corner of the state. Bone collagen carbon isotope values become more positive towards the arid north in relation to increasing quantities of C4 grasses. Thus, stable carbon isotope analysis of bone specimens provides a method to address dietary selection and dietary variability in Australian herbivores. In addition, isotopic analyses of archaeological and palaeontological bones and teeth can be used to address changes in Quaternary climate and vegetation distributions in Australia.

Carbon and nitrogen isotope ratios of (1) bone collagen from six burials of the Late Woodland Period at Nantucket Island, Massachusetts, and (2) a wide range of potential dietary materials provide data for evaluating coastal diets. Archaeological and historical data give evidence for the availability and use of dietary items. The bases of the food chains and trophic levels define the possible food groups: terrestrial C3 and C4 plants and their consumers, marine C3 and C4-like plants and their consumers, and marine carnivores. From these data, computer analysis of multiple linear mixing equations relating isotope ratios of human bone collagen to those of dietary food groups shows allowable ranges of these food groups in the diet. The results argue for a diet of 40–65 percent oceanic animals, with the rest consisting of substantial amounts of animals from salt marsh and eelgrass meadows or of maize, and minor amounts of C3 plants and their consumers.

Following the entry of Zea mays to northeast North America, Northern Iroquoian populations expanded their numbers and range. Isotopic values from bone collagen have shown fluctuations in reliance on this dietary staple. With permission of the Huron-Wendat Nation of Wendake, Quebec, we measured δ13Cenamel, δ13Cdentine and δ15Ndentine from 167 permanent teeth, retained before reburial of their ancestral skeletons, and δ13Ccollagene and δ15Ncollagene from adhering bone (n = 53). Enamel values encapsulate diet from ca. 1.5 to 4 years of age; dentine values reflect later childhood. Teeth are from 16 ancestral Huron-Wendat sites in southern Ontario. Isotopic values show consistent reliance on maize from early fourteenth to sixteenth centuries, with higher reliance in the seventeenth century—the time of contact with Europeans and disruptive changes. We show a difference between the diets of children and adults; children consumed more maize and less animal protein. Whitetailed deer (Odocoileus virginianus) did not exploit maize fields, reflecting hunters’ exploitation of distant regions. New values from fish species (n = 21) are pooled with prior data, demonstrating diverse C and N stable isotope patterns. American eel (Anguilla rostrata) is particularly variable. Dietary protein sources were variable compared to the stability of maize: a reliable source of carbohydrate food energy across four centuries.

The technique of surrounding virus particles with a neutralised electron dense stain was described at the Fourth International Congress on Electron Microscopy, Berlin 1958 (see Home & Brenner, 1960, p. 625). For many years the negative staining technique in one form or another, has been applied to a wide range of biological materials. However, the full potential of the method has only recently been explored following the development and applications of optical diffraction and computer image analytical techniques to electron micrographs (cf. De Hosier & Klug, 1968; Markham 1968; Crowther et al., 1970; Home & Markham, 1973; Klug & Berger, 1974; Crowther & Klug, 1975). These image processing procedures have allowed a more precise and quantitative approach to be made concerning the interpretation, measurement and reconstruction of repeating features in certain biological systems.
