Abstract

Treats to the integrity of biodiverse Amazon floodplain habitats from deforestation, dams and climate change are increasingly severe but to date, Amazon biodiversity scenarios have not considered these critical environments. Building on decades of floodplain-focused research in the Amazon by consortium members, we will improve characterization of Amazonian whitewater floodplain habitats and inundation dynamics, so as to 1) scale up existing fish, floodplain florest and phytoplankton biodiversity datasets, 2) evaluate the potential impacts of regional drivers such as climate, land use change, and dams on floodplain habitats, and 3) engage at local and regional scale a large panel of stakeholders in looking for sustainable strategies for wetlands preservation. The scenarios produced at both scales will be compared in therms of wetlands conservation and biodiversity descriptors including Essential Biodiversity Variables and Sustainable Development Goals indicator. Our study framework focusing on the floodplains of the main stem Amazon River (Brazil and Colombia) and Jurua River (Brazil) allows comparison between whitewater floodplains sites contrasting greatly in terms of floodplain geomorphology, land use and management history, commercial fishishg pressure and human population density. Innovative aspects of our work include: 1) testing a remote-sensing based approach for mapping phytoplankton biodiversity in floodplain lakes; 2) use of new satellite data to greatly increase the spatiotemporal resolution of floodplain habit and inundation maps; 3) use of environmental eDNA metabarcording to examine the distribution and relative abundance of phytoplankton, zooplankton and fish in floodplain lakes; 4) individual-based modelling of Levy-flight fish foraging patterns across a network of oxbow lakes; and 5) nested-scale agent-base participatory models to develop scenarios. The proposed work will greatly expand available information for decision making to support the vast biodiversity and extensive ecosystem services provided by Amazon whitewater floodplains. (AU)
