Ancient Biological Invasions and Island Ecosystems: Tracking Translocations of Wild Plants and Animals

Biological invasions are one of the great threats to Earth’s ecosystems and biodiversity in the Anthropocene. However, species introductions and invasions extend deep into the human past, with the translocation of both wild and domestic species around the world. Here, we review the human translocation of wild plants and animals to the world’s islands. We focus on establishing criteria used to differentiate natural from human-assisted dispersals and the differences between non-native and invasive species. Our study demonstrates that, along with a suite of domesticates, ancient people transported numerous wild plants and animals to islands and helped shape ecosystems in ways that have important ramifications for modern conservation, restoration, and management.     

The Movement and Exchange of Dogs in the Prehistoric Caribbean: An Isotopic Investigation

This study explores the feasibility of using strontium isotope (⁸⁷Sr/⁸⁶Sr) analyses of enamel from domestic dogs (Canis familiaris) to investigate networks of exchange in the prehistoric Circum‐Caribbean. Dog teeth were obtained from burial and domestic contexts from two prehistoric sites (Anse à la Gourde and Morel) on Grande‐Terre, Guadeloupe (Lesser Antilles). Strontium isotope results were compared with local biosphere ⁸⁷Sr/⁸⁶Sr data at the scale of the site, island and archipelago. The isotope results indicate both local and nonlocal origins with three dogs (30%) identified as nonlocal (one from Anse à la Gourde and two from Morel). The variance in ⁸⁷Sr/⁸⁶Sr ratios of the nonlocal dog teeth is consistent with diverse multiple origins external to the island of Grande‐Terre but consistent with origins from other islands of the Lesser Antilles. The diverse origins of the nonlocal dog samples indicate that the prehistoric circulation of dogs occurred at multiple scales from regional to long distance. Significantly, the ⁸⁷Sr/⁸⁶Sr ratios of some of the dog teeth are comparable with values of nonlocal humans at Anse à la Gourde determined in previous studies. It is possible that these comparable ⁸⁷Sr/⁸⁶Sr ratios result from similar natal origins, for example if individuals were migrating to Guadeloupe with dogs. The results of this study contribute to an ongoing regional investigation of the economic, social and political roles of animals and animal remains and the multiscalar networks of prehistoric mobility and exchange in the Circum‐Caribbean region.

The Central Institute for Brain Research in Amsterdam and its Directors

The Central Institute for Brain Research was founded in Amsterdam in 1908 as part of an international effort to study the nervous system with multiple institutions and various disciplines. The development of research in the past hundred years at the Brain Institute has hardly been documented. We analyze the history of this institute by means of brief portraits of its directors and their main research topics. It appears that each director introduced his own branch of neuroscience into the institute. Initially, mainly comparative neuroanatomical data were collected. Following the Second World War, the multidisciplinary approach slowly developed with research programs on systems neuroscience, neuroendocrinology, and brain disorders. Every new director introduced new approaches to the study of the brain and thus played an important role in keeping brain research in the Netherlands at the international forefront where it has been ever since its foundation in 1908.     

Determining the Provenance of Cayo Pottery from Grenada,Lesser Antilles,Using Portable X‐Ray Fluorescence Spectrometry

Portable XRF was used to analyse the chemical composition of 52 indigenous Cayo ceramics from excavations and from private collections on Grenada, Lesser Antilles. Initially, a comparative baseline of data representing three different islands (Grenada, St Vincent and Trinidad) was created by analysing with pXRF ceramic material that had previously been analysed both chemically and petrographically. The field data, when compared to the laboratory baseline data, indicated that the majority of the ceramics were made with clay local to Grenada. Four samples were potentially made with clay from another, as yet unidentified, source.     

An obligation of conscience: gossip as social control in an eighteenth-century Flemish town

This article investigates how gossip developed as a tool of social control in eighteenth-century Kortrijk, an average-sized town in Flanders. Through gossip, people influenced others' behaviour, by performing social norms, by punishing violators of norms, by publicising the punishments of these deviants, and finally, by spreading information about improper behaviour, possibly leading to other sanctions. Previous research has insufficiently considered how the effects of gossip as social control were influenced by the historical situations in which it occurred. Most notably, the decline of honour and the formalisation of social control altered the ways in which people could effectively use the power of gossip, as in the second half of the eighteenth century, gossip was less a direct deterrent of deviant behaviour, but became more important in formal control settings.

Working the Yucatán in the neoliberal landscape: household management,consumption and the lives of intellectual elite women

This article examines the lives of academic women in Mérida, the state capital of the Yucatán in southern Mexico. In particular, I consider the relationship between work – including household management – and consumer practices in light of Mérida's changing socioeconomic climate. I address how women's lives have been impacted by the neoliberal restructuring of Mexico's political economy and what these changes mean to their experience of university life, household management styles and consumption practices. I point out how labor and consumption are deeply interrelated cultural practices, which have acquired new meanings in the neoliberal landscape. Accordingly, consumption practices must be understood in connection with women's social and professional identities.     

Spatial variation of biologically available strontium isotopes (Sr/Sr) in an archipelagic setting: a case study from the Caribbean

This paper presents the results of strontium (Sr) isotope analysis of modern and archaeological animal remains and modern plant samples from the Caribbean region. The goal is to assess if patterns of human mobility can be determined from the archaeological record in an archipelagic setting. The range of variability and spatial distribution of biologically available strontium isotope signatures is reported and data evaluated to determine if sufficient heterogeneity exists to permit the identification of mobility despite the presence of potentially large contributions of marine strontium in island and coastal ecosystems. The (is)landscape is divided into several sub-regions based on the age and lithology of underlying geology and the variability of ⁸⁷Sr/⁸⁶Sr ratios is reported as; mean ⁸⁷Sr/⁸⁶Sr ± 2 standard deviations, number of samples: 1) Volcanic and Intrusive rocks (0.7077 ± 0.0019; n = 162); 2) Cretaceous–Miocene Limestone (0.7085 ± 0.0009; n = 50); 3) Pliocene–Quaternary Limestone (0.7091 ± 0.0004; n = 54); 4) Sedimentary Deposits (0.7094 ± 0.0015; n = 16); 5) Metamorphic Deposits (0.7104 ± 0.0014; n = 6). There are substantial differences between expected ⁸⁷Sr/⁸⁶Sr values based on associated geology and measured ⁸⁷Sr/⁸⁶Sr in flora and fauna samples. These differences emphasize the importance of focusing on bioavailable strontium, as opposed to geological proxies, for estimations of Sr isotope ranges, especially in archipelagic environments. While some overlap exists between the ⁸⁷Sr/⁸⁶Sr ranges of certain sub-regions, other sub-regions possessed limited variation and could be distinguished based on strontium isotope data. This spatial patterning of biologically available strontium indicates that strontium isotope analyses can be successfully applied to the archaeological study of human mobility within the Caribbean region.
