A global meta-analysis of the impacts of forest fragmentation on biotic mutualisms and antagonisms

Forest fragmentation is a grave threat to biodiversity. Forests are becoming increasingly fragmented with more than 70% now < 1 km from forest edge. Although much is known about the effects of forest fragmentation on individual species, much less is understood about its effects on species interactions (i.e., mutualisms, antagonisms, etc.). In 2014, a previous meta-analysis assessed the impacts of forest fragmentation on different species interactions, across 82 studies. We pooled the previous data with data published in the last 10 years (combined total 104 studies and 168 effect sizes). We compared the new set of publications (22 studies and 32 effect sizes) with the old set to evaluate potential changes in species interactions over time given the global increase in fragmentation rates. Mutualisms were more negatively affected by forest fragmentation than antagonisms (p < 0.0001). Edge effects, fragment size, and degradation negatively affected mutualisms, but not antagonisms, a different finding from the original meta-analysis. Parasitic interactions increased as fragment size decreased (p < 0.0001)—an intriguing result at variance with earlier studies. New publications showed a more negative mean effect size of forest fragmentation on mutualisms than old publications. Although research is still limited for some interactions, we identified an important scientific trend: current research tends to focus on antagonisms. We concluded that forest fragmentation disrupts important species interactions and that this disruption has increased over time. © 2023 The Authors.

Sources of community : mythical groundwork of Early Modern identities

Jakub Koryl’s lengthy chapter, “Sources of Community: Mythical Groundwork of Early Modern Identities”, stands out in terms of its theoretical nature and comprehensive scope. At the same time it goes to the heart of the question of confessional identity and otherness, and thus provides an illuminating perspective on many of the themes covered in both this section and the volume as a whole. Drawing on case-studies from both the Lutheran and Catholic Reformation, Korylseeksto offer a newaccount of confessional-identity building from the late Middle Ages through to the Enlightenment. In particular, he argues that in the early modern period the theme of myth - and especially the rival German and Roman “myths” of Reformation - became the driving force for the creation of new confessional identities, harnessing and uniting into one powerful synthesis, social, intellectual, political and religious forces. Then, following in the footsteps of Hans Blumenberg, Charles Taylor and others, Koryl traces the roots of the modern conception of identity to late medieval Nominalism and its overturning of the medieval analogical and hierarchical understanding of reality. According to Koryl, it was this philosophical move which helped release the creative - and destructive - interplay of forces that shaped the early modern confessional landscape for the next two centuries. Importantly, this situation gave minority views a new voice in European affairs, allowing them eventually to construct their own (secular) myths and take on the dominant, majority role they exercise in the world today
