Abstract

Stable isotope data have made pivotal contributions to nearly every discipline of the physical and natural sciences. As the generation and application of stable isotope data continues to grow exponentially, so does the need for a unifying data repository to improve accessibility and promote collaborative engagement. This paper provides an overview of the design, development, and implementation of IsoBank (www.isobank.org), a community-driven initiative to create an open-access repository for stable isotope data implemented online in 2021. A central goal of IsoBank is to provide a web-accessible database supporting interdisciplinary stable isotope research and educational opportunities. To achieve this goal, we convened a multi-disciplinary group of over 40 analytical experts, stable isotope researchers, database managers, and web developers to collaboratively design the database. This paper outlines the main features of IsoBank and provides a focused description of the core metadata structure. We present plans for future database and tool development and engagement across the scientific community. These efforts will help facilitate interdisciplinary collaboration among the many users of stable isotopic data while also offering useful data resources and standardization of metadata reporting across eco-geoinformatics landscapes.

Abstract

Winter conditions impose dramatic constraints on temperate, boreal, and polar ecosystems, and shape the abiotic and biotic interactions underpinning these systems. At high latitudes, winter can last longer than the growing season and may have a disproportionately large impact on organisms and ecosystems. Even so, our understanding of the ecological implications of winter is often lacking. Indeed, even what exactly defines winter is currently unclear, and boundaries that delineate this season are blurred across marine, freshwater, and terrestrial realms and fields of biology. Here, we discuss the complexity of defining winter, and highlight the importance of maintaining the capacity to test hypotheses across seasons, realms, and domains of life. We then outline questions drawn from diverse fields of research that address current gaps in our understanding of winter ecology and how winter influences multiple levels of biological organization, from individuals to ecosystems. Finally, we highlight the potential consequences of changes to both the length and severity of winter due to climate change, and discuss the role winter may play in mediating ecosystem function in the future. Key words: climate change, communities, ecosystems, individuals, populations. Les conditions hivernales imposent des contraintes dramatiques aux ecosystemes temperes, boreaux et polaires, et elles faconnent les interactions abiotiques et biotiques qui soutiennent ces systemes. Aux hautes latitudes, l'hiver peut durer plus longtemps que la saison de croissance et il peut avoir un impact disproportionne sur les organismes et les ecosystemes. Malgre cela, notre comprehension des implications ecologiques de l'hiver est souvent insuffisante. En effet, meme ce qui definitexactementl'hiver n'est pas clair actuellement et les frontieres qui delimitent cette saison sont floues a travers les domaines marins, d'eau douce et terrestres et les champs de la biologie. Les auteurs discutent ici de la complexite de definir l'hiver et soulignent l'importance de maintenir la capacite de tester des hypotheses a travers les saisons, les roy-aumes et les domaines de la vie. Ils presentent ensuite des questions tirees de divers domaines de recherche qui visent a combler les lacunes actuelles dans notre comprehension de l'ecologie hivernale et de la facon dont l'hiver influence de multiples niveaux d'organisation biologique, des individus aux ecosystemes. Enfin, ils soulignent les consequences potentielles des changements de la duree et de la rigueur de l'hiver dus aux changements climatiques et discutent du role que l'hiver pourrait jouer dans la mediation de la fonction des ecosystemes dans le futur.

30. Art and Awe in Secret Societies: A Case Study of the Petroglyph Site at Thorsen Creek, British Columbia.

Abstract

The origin of art has been an enduring issue in archaeology since the nineteenth century with many contending theories. While we are not concerned here with the origins of simple image-making (images consisting of patterned scratches or minimal representations), we would like to propose that one important reason for the elaboration and widespread use of more labor intensive and complex images--especially those requiring considerable time, effort, and training--may be the need for impressive images by traditional secret societies. We document such elaborations ethnographically and point out the inherent reasons for investing in them by secret societies. Beginning with complex hunter/gatherers, secret societies had the motivations, the resources, and the psychological insights to develop sophisticated art and architecture, resulting in some of the most impressive displays in prehistory. We use the remarkable petroglyph site of Thorsen Creek in British Columbia as a prime case study. [ABSTRACT FROM AUTHOR]
