Résumé
The Early-Late Pliocene transition (â¼ 3.6 Ma) is a key period for understanding future climate change linked to increases in greenhouse gases. Around the Western Mediterranean Basin, the Early-Late Pliocene transition was marked by the establishment of a Mediterranean climate with summer droughts, cool/wet winters and latitudinal gradients. However, environmental changes in the eastern part of the Mediterranean area during the Early-Late Pliocene transition have rarely been documented. Here, we propose to reconstruct the environmental and climate changes during the Early-Late Pliocene transition from the Burdur Basin sequence, located in Southwestern Türkiye. This study aims to (1) characterize vegetation patterns, lake dynamics, and water level fluctuations using pollen and Non-Pollen Palynomorph (NPP) proxies, and (2) examine the morphological features of large Poaceae pollen grains (Cerealia-type). We also aim to quantitatively reconstruct climate changes through a multi-method approach, including the Modern Analogue Technique, Weighted Averaging Partial Least Squares regression, Random Forest, and Boosted Regression Trees and the Climatic Amplitude Method.
