This data publication encompasses the datasets generated in a study focusing on reconstructing ecological responses to climatic and nutrient availability changes during the late Holocene in northern Philippines. The data comes from samples taken from sediment cores retrieved from Bulusan Lake, located on Luzon Island, Philippines, in March 2013. In these samples, we analyzed fossil pollen and spores (a proxy for plant taxa abundance), charcoal (a proxy for fire activity), stable carbon isotopic composition of terrestrial-lipid biomarkers (a proxy for vegetation cover), stable nitrogen and phosphate isotope composition of bulk sediments, and elemental composition of sediment cores at a high resolution (proxies for nutrient availability and volcanic activity). The dataset also includes links to records generated in a previous study on the same sediments (Prohaska et al. 2023), where we measured the stable hydrogen isotopic composition of terrestrial-lipid biomarkers to reconstruct past hydrological conditions, as well as the magnetic susceptibility record and AMS dates of plant macrofossils to calculate sediment accumulation ages. The data generation spanned the period from April 2013 to September 2020, and the data files are provided in Excel spreadsheet format.

Information on how the data have been collected and processed is provided in the published article.
