Resumen:
Preliminary High-latitude fungal palynology of coals and interseam rocks leading to the Miocene Climate Optium warming event, Victoria, Australia. Fungi are necessary elements in all ecosystems given their role in terrestrial carbon cycling, soil formation, plant growth, and more, and it´s critical to understand how they may change with global warming. We know that fungal communities from the middle Miocene in the northern high latitudes vary with shifting climates, however we do not know if this also occurred in southern high latitudes. The analysis of fungal assemblages from lower-middle Miocene sediments during the lead up to and through the Miocene Climate Optimum (MCO; 18-13 Ma), especially from the M1B coal, Yallourn Interseam Rocks, and Yallourn Coal in Victoria, Australia, is key to understand these changes. We are examining changes across the MCO because it is a best analog for current and future climate change. Preliminary results indicate that the fungal assemblages of M1B and Yallourn Coal sediments are highly diverse. The Yallourn Interseam, between the two coals, is less diverse. This study is a part of a large-scale international project that is assessing the response of fungal assemblages climate change across temporaland geographical scales. To date, our research suggests that fungal communities are changing in relation to climatic changes previously documented by plant palynology.
