Pollen analysis of a 300 cm deep guano deposit from Magurici Cave, N.W. Romania was performed in order to highlight the vegetation dynamics and the influence of deforestation and agricultural activities that unfolded in the area over the last 800 years.
The obtained data is consistent with the known vegetation history over the late Subatlantic period, with well known climatic events recorded, such as MCA (Medieval Climate Anomaly) and LIA (Little Ice Age). Agriculture’s influence on vegetation is also shown, especially in modern times, by the decrease of arboreal pollen, increase of herbaceous taxa related to grazing and the occurrence of cereal taxa.
Further studies and comparison with other guano sites are required to identify the long-term ecological response of bats to environmental changes.
