Late Quaternary vegetation, biodiversity and fire dynamics on the southern Brazilian highland and their implication for conservation and management of modern Araucaria forest and grassland ecosystems

Palaeoecological background information is needed for management and conservation of the highly diverse mosaic of Araucaria forest and Campos (grassland) in southern Brazil. Questions on the origin of Araucaria forest and grasslands; its development, dynamic and stability; its response to environmental change such as climate; and the role of human impact are essential. Further questions on its natural stage of vegetation or its alteration by pre- and post-Columbian anthropogenic activity are also important. To answer these questions, palaeoecological and palaeoenvironmental data based on pollen, charcoal and multivariate data analysis of radiocarbon dated sedimentary archives from southern Brazil are used to provide an insight into past vegetation changes, which allows us to improve our understanding of the modern vegetation and to develop conservation and management strategies for the strongly affected ecosystems in southern Brazil

Interpreting conversion in antiquity (and beyond)

This essay explores the persistent scholarly desires and motivations that structure the historical study of conversion in religious studies. Most “conversion studies” take a phenomenological approach, which acknowledges the diverse processes, contexts, and meanings of conversion but nonetheless sees the phenomenon as a way to access the contours of global religion. Phenomenology of conversion reveals a desire for bounded religions arranged in a comparable system, “religion.” A hermeneutical approach to conversion does not seek to access a stable phenomenon but asks why conversion as a discourse is deployed. This form of narrative interpretation can open up new possibilities in what we think the study of religion can, and should, do. The specific examples of Jewish conversion to Christianity in late antiquity act as case studies
