Stromatolites represent exceptional geochemical archives recording microbial metabolism and environmental evolution throughout Earth's history. High-resolution analytical techniques, particularly femtosecond laser ablation ICP-MS (FS-LA-ICP-MS), enable unprecedented micro-scale mapping of trace elements and isotopes within stromatolitic laminae. This seminar presents our integrated approach at Tongji University's Carbonate Geochemistry Laboratory, combining elemental mapping, rare earth element systematics, and redox-sensitive trace metals to reconstruct paleo-environmental conditions in Precambrian microbial habitats. Elemental maps reveal metal partitioning reflecting redox gradients, microbial processes, and diagenesis, while also guiding strategic sampling for isotope analysis and U-Pb dating where biostratigraphic markers are absent. Beyond scientific findings, this talk highlights collaborative research opportunities, funding mechanisms, and career pathways for early career researchers in China's dynamic geoscience community.

Tropical carbonate platforms are an important coastal ecosystem, comprising a series of shallow benthic habitats, including coral reefs, seagrass meadows, tidal flats and channels. The habitats on carbonate platforms are highly spatially heterogenous and dynamic. Assessing the change rate, change pattern, and understanding the causes of such changes (if there are any) is important, from both the ecological and geological points of view. However, the observations on the coastal systems have time biases: it either very short (few years) or very long (from cores, > 1000 years), and we lack observations acquired at an intermediate timescale (decades) to bridge habitat dynamics observed today with the rock records from the cores. In this study, we used one of the oldest aerial photos from 1945 to constrain the habitat dynamics and compare the habitat distributions with that of today.

The origin of mammals involved major reorganization of the locomotor system, from ‘sprawling’ to ‘erect’ limb postures. Yet, despite a rich fossil record, how this shift was achieved has remained challenging to decipher. This talk will summarize recent efforts to integrate the fossil record of mammals and their non-mammalian synapsid ancestors with modern animal anatomy and computational biomechanics. These have helped clarify evolutionary patterns of anatomical transformation, and the timing of major functional shifts. A fully erect limb posture evolved much later than originally thought, well within crown-group mammals. Far from being an orderly, linear narrative, the sprawling-to-erect transition in synapsids is becoming understood as a highly complex, nonlinear, and protracted event.

Marine phytoplankton play an important part within the global carbon cycle, removing great amounts of carbon from the atmosphere and producing around half of the atmospheric oxygen today. Furthermore, forming the largest part of the base of aquatic food chains, phytoplankton represent the starting point of biological activities in the oceans. Therefore, the study of ancient phytoplankton dynamics at regional and global scales can provide valuable insights into the evolution of marine ecosystems.

Ganoid scales and fish teeth can be found around the world and through deep time. By creating a classification of the preservation of these fossils, distinctive patterns were discovered. Analysing the abrasion of these objects can tell us more about the energy level of the environment and how far the fossils were transported post mortem. To verify my hypothesis, an experimental approach is now in the works using specimens from different geological epochs. If successful, aquatic paleoenvironments can be interpreted in high detail.

The South Pacific was the final frontier of human colonisation on Earth. Human migration across the Pacific occurred in two waves, the first starting around 3000 yr BP and then after a long pause of 2000 years, the second occurred at approximately 1000 yr BP. Reasons for these migrations are contested, but climate is increasingly thought to have been a factor. This work utilised a combination of multi-proxy palaeo records and socio-ecological modelling to investigate the role of climate in the timing of migration and colonisation in the tropical South Pacific. The key finding from the palaeoenvironmental records is evidence for a shift towards dry conditions around the second wave of human migration into Eastern Polynesia and again in the relatively early stages of colonisation. The model outputs suggest that drought has a greater impact on population dynamics the closer to the absolute carrying capacity the population gets and that severity of the drought rather than the frequency is the key factor determining the impact of a drought on agricultural outputs and population dynamics.
