Editorial preface to special issue: Life and environments in transition: The Neoproterozoic-early Paleozoic world
This Virtual Special Issue (VSI) presents insights from the Proterozoic-early Paleozoic world, a critical interval for the co-evolution of life and environments in Earth's history. The 16 papers in this VSI are broadly organized into three themes. The first theme presents new fossil discoveries within a refined geochronological framework, revealing limited biotic competition and a strong palaeoenvironmental control on the spatial distribution of life in the Ediacaran ocean. The second theme focuses on paleoenvironmental reconstruction. The results point to a complex, non-linear evolution of marine redox conditions, carbon cycling and continental weathering, challenging the idea of a simple environmental control on biological evolution. The third theme highlights the key role of oceanic redox conditions in the formation of phosphorus and manganese ores. Together, these studies suggest that understanding the co-evolution of life and environments during the Neoproterozoic-early Paleozoic requires a geosystems perspective incorporating a combination of interconnected tectonic, climatic, oceanic, ecological, and bioevolutionary drivers.
期刊介绍:
The objective of the journal Global and Planetary Change is to provide a multi-disciplinary overview of the processes taking place in the Earth System and involved in planetary change over time. The journal focuses on records of the past and current state of the earth system, and future scenarios , and their link to global environmental change. Regional or process-oriented studies are welcome if they discuss global implications. Topics include, but are not limited to, changes in the dynamics and composition of the atmosphere, oceans and cryosphere, as well as climate change, sea level variation, observations/modelling of Earth processes from deep to (near-)surface and their coupling, global ecology, biogeography and the resilience/thresholds in ecosystems.
Key criteria for the consideration of manuscripts are (a) the relevance for the global scientific community and/or (b) the wider implications for global scale problems, preferably combined with (c) having a significance beyond a single discipline. A clear focus on key processes associated with planetary scale change is strongly encouraged.
Manuscripts can be submitted as either research contributions or as a review article. Every effort should be made towards the presentation of research outcomes in an understandable way for a broad readership.
