Ecological Dynamics of Pleistocene reef corals
Fossil and modern ecological communities are dynamic both temporally and spatially and respond to changes in environmental and climatic conditions. The Middle – Late Pleistocene (~1.0 – 0.01 Ma) climate is characterized by the intensification of cyclic oscillations between glacial (cool, low sea level) and interglacial (warm, high sea level) intervals. The fossil record, preserving a long-term dataset of coral reef communities composed of extant species, reveals that reef corals have persisted throughout the Pleistocene despite these multiple dramatic climate fluctuations, some of which are similar in magnitude to modern climate change. Although it provides a valuable ecologic resource, the Early – Late Pleistocene history of coral reef ecology remains largely unexplored, particularly in relation to climate changes during this critical period of reef expansion, and persistence, into modern reef ecosystems. My PhD project integrates taxonomic and trait-based paleontological data with paleoclimate interpretations and extant reef ecology to quantitatively evaluate the temporal distribution of coral taxa and functional traits in relation to multiple episodes and rates of climate change across the Pleistocene.
The overarching goal of this project is to highlight the effects of past global climate and environmental change on the biogeography of reef community composition and genera functionality. Specifically, my project investigates temporal and spatial variability of coral composition and functional dynamics 1) across the Middle – Late Pleistocene, an interval characterized by global climate transitioning; 2) by comparing Pleistocene and Modern coral assemblages at the same localities, and 3) by providing the first taxonomic description of Pleistocene azooxanthellatae corals from Western Australia and relating this assemblage to changing regional environmental conditions. The research findings will enhance our understanding of the relative response of coral community structure and functional traits to relatively rapid climate change as well as the biogeographic variability of these responses, both of which will inform our predictions of how coral assemblages may persist under future climate conditions and thereby aid in the management of modern marine ecosystems.
