This project will utilize large and unique museum collections of exquisite, three-dimensionally preserved plants and associated invertebrates, fungi and micro-organisms entombed in silicified peats, hot-spring cherts and equivalent deposits to clarify the temporal and evolutionary patterns in the development of a range of key biological interactions that are important for the functioning of terrestrial ecosystems.
Using cutting-edge microscopy and tomography techniques, this project will investigate the remarkable three-dimensionally preserved anatomy of fungi, invertebrates and plants within unique organic accumulations permineralized by silica and calcium-carbonate and entombed in leech hirudoin secretions. Using these techniques, details down to the level of cell nuclei, organelles and even individual chromosomes can now be resolved.
Anatomical data obtained from reproductive structures preserved in these deposits will contribute to an improved understanding of the evolutionary history and reproductive biology of a range of seed- and spore-producing plants and fungi.
Investigation of linkages between the entombed organisms will provide unparalleled insights into the evolution of cryptic land biotas through time and shed light on the development of biological interactions, such as mycorrhizal symbioses, saprotrophism, parasitism, mutualism, herbivory and reproduction, that are key to nutrient and energy cycling in terrestrial ecosystems.
