"QUERCUS ILEX L. TÜRÜNÜN GÜNÜMÜZ VE GELECEKTEKİ OLASI YAYILIŞI İLE İKLİM DEĞİŞİKLİĞİNE UYUM YETENEĞİNİN DEĞERLENDİRİLMESİ"

Abstract

"Future climate projections for the Mediterranean basin, where the effects of climate change are highly felt, revealed that there will be changes in the habitats of trees. In this context, the aim of the study is to evaluate the current and future distribution and adaptation ability of Quercus ilex L. (Holm oak) within the context of climate change. Within the scope of TÜBİTAK Project numbered 117O982, incremental cores, woods and leaf samples were taken from 102 different research points covering all natural areas in Türkiye, which is the easternmost border of its worldwide distribution. According to the species distribution models obtained based on the climate scenarios used, the presence of the species in the South Aegean Region will continue in the 2070s, albeit decreasing, whereas the Black Sea and Marmara Regions will become more suitable for the distribution of the species. Thus, the amount of land suitable for the distribution of the species in terms of climate will increase in Türkiye. It was concluded that the adaptation power of water transporting systems and tree rings in the woods of the species and its leaf characteristics is high. Therefore, it is predicted that the species will be resistant to the changing climatic conditions in suitable growing areas of the Aegean, Marmara and Black Sea region. For this reason, it can be recommended to preserve the natural distribution areas of the species in the Aegean, Marmara and Black Sea regions, to cultivate it in forest areas close to sea level and the coast, and to prefer it more in urban groves, parks and roads."
