Overview

Thomas Litt is affiliated with the University of Bonn in Germany and conducts research primarily in Earth and Planetary Sciences. Their work spans several subfields, including Atmospheric Science, Paleontology, Archeology, Ecology, and Earth-Surface Processes. The research focuses on topics such as Geology and Paleoclimatology, Archaeology and ancient environmental studies, Maritime and Coastal Archaeology, Isotope Analysis in Ecology, Archaeology and Historical Studies, Lichen and fungal ecology, and Fire effects on ecosystems.

Thomas Litt has contributed to multiple publications, with frequent appearances in the journal Boreas. Other publication venues include Communications Earth & Environment, Quaternary Research, PLoS ONE, and Radiocarbon. Their recent papers illustrate a range of interdisciplinary interests:

  • "Volcanic impact on terrestrial and aquatic ecosystems in the Eastern Mediterranean" (2023, Communications Earth & Environment)
  • "Al-Ansab and the Dead Sea: Mid-MIS 3 archaeology and environment of the early Ahmarian population of the Levantine corridor" (2020, PLoS ONE)
  • "NEW APPROACH TO SEPARATE AND DATE SMALL SPORES AND POLLEN FROM LAKE SEDIMENTS IN SEMI-ARID CLIMATES" (2022, Radiocarbon)
  • "A Late Holocene climate reconstruction from the high-altitude Lake Gölcük sedimentary records, Isparta (SW Anatolia)" (2023, Quaternary Research)
  • "Changing fire regimes during the first olive cultivation in the Mediterranean Basin: New high-resolution evidence from the Sea of Galilee, Israel" (2022, Global and Planetary Change)

Their research frequently involves collaboration with several co-authors, including Jan A. Piotrowski, Nicolaj K. Larsen, Ole Bennike, Michael Houmark-Nielsen, and Juha Pekka, each appearing as a recurrent collaborator with multiple joint publications.

The scientific contributions of Thomas Litt cover a broad array of subjects linking geological and climatic processes with archaeological and ecological studies. Their work on volcanic influences, ancient population environments, pollen and spore dating methods, climate reconstructions in Mediterranean regions, and fire regimes related to early agricultural practices demonstrates an interdisciplinary scope grounded in field and laboratory research.

Thomas Litt's publication record and active collaborations highlight a consistent engagement with research themes central to understanding Earth's past environments and their interactions with human history and ecological systems.
