The paper aims to define the natural distribution of Olea europaea L. var. sylvestris (Miller) Lehr. in the North Mediterranean basin during the Pleniglacial and the Early-Middle Holocene by means of the identification of its wood-charcoal and/or wood at prehistoric sites.For this purpose we have reviewed the previously available information and we have combined it with new wood-charcoal analyses data. We have taken under consideration the presence and frequency of Olea europaea L. in the available wood-charcoal sequences, the characteristics of the accompanying flora, the associated chrono-cultural contexts, the broader biogeographical context and the AMS dates provided by Olea wood-charcoal or endocarps.According to the available evidence, during the Middle and Late Pleniglacial (c. 59-11,5 ka cal. BP), Olea would have persisted in thermophilous refugia located in the southern areas of the North Mediterranean basin, the southern Levant and the north of Africa. The Last Glacial Maximum (c. 22-18 ka cal. BP) probably reduced the distribution area of Olea. During the Preboreal and the Boreal (c. 11 500-8800 cal. BP) the species started to expand in the thermomediterranean bioclimatic level. In the western Mediterranean, during the Atlantic period (c. 8800-5600 cal. BP), the species became very abundant or dominant in the thermophilous plant formations and expanded to favorable enclaves outside the limits of the thermomediterranean level.

“…Large-sized fans evolved during the Holocene under a warm climate, characterised by an increasing aridification, seasonality, and sparse vegetation cover, progressively cleared during the Late Holocene by human activity as indicated by the increase of ruderal species in the recent palynological record (Carrión et al, 1995(Carrión et al, , 1999. Climate today can be classified as steppe to desertic type (Köppen Classification), with mean annual precipitation below 300 mm/yr, and mean annual evapotranspiration up to 1000 mm/yr (López Gómez and López Gómez, 1987), triggering a marked hydrological deficit with a semiarid behaviour.…”

“…Many palaeoecological-research studies have been carried out on palynology of cave sediments, including bat guano and coprolites from other taxa and surface soil in different part of the globe, such as in Romania (Pop and Ciobanu, 1950;Boscaiu and Lupsa, 1967a,b;Feurdean et al, 2011;Geanta et al, 2012), the United States (Sears and Roosma, 1961;Davis, 1990;Nieves-Rivera 2003;Maher, 2006;Batina and Reese, 2011), Switzerland (Groner, 2004), Austria (Kral, 1968;Draxler, 1972), the UK (Coles et al, 1989;McGarry and Caseldine, 2004), Spain (Carrió n, 1992;Carrió n et al, 1999Carrió n et al, , 2006Navarro Camacho et al, 2000, 2001, Belgium (Bastin, 1978;Bastin et al, 1986), Nepal (Denniston, et al, 2000), China (Qin et al, 1999;Zhang et al, 2004), and other parts of Asia (Hunt and Rushworth, 2005).

Meghalaya is well known for its rich tropical biodiversity and numerous natural caves. The Siju Cave of Meghalaya, also known as cave of the bat, is among the longest caves on the Indian subcontinent. The palynological study of fifty bat-guano samples from Siju Cave and of thirty surface soil and moss cushion from the area immediate surrounding the cave reflects the close similarity between the modern pollen and vegetation in the region in the two areas sampled. The resulting palynodata comprise mainly the native flora, dominated by riparian taxa like Duabanga, Syzygium, Careya, and Ficus, along with evergreen and deciduous elements in the region. The evergreen taxa Mesua, Elaeocarpus, and Garcinia, along with Impatiens, reflect the high precipitation in the region. The climate of the region and the vegetation are strongly influenced by the Simsang River, and the heavy rainfall results in the dominance of riparian taxa and other high-rainfall indicator taxa. The occurrence of pollen from Nepenthes khasiana, an endemic and endangered plant of Meghalaya, in bat guano is significant and may be due to its insectivorous and entomophilous nature. However, medicinal plants like Swertia chirata, Cinchona, and Rauvolfia are not encountered in the bat-guano sediments, despite their luxuriant growth around the cave, and these species could be avoided by the insects due to their alkaloid contain and bitter taste. The presence of highland taxa such as Pinus, Abies, Picea, and Larix in the bat guano deposit is significant and suggestive of high winds from higher altitudes, or the pollen may be introduced by the return of migratory Siberian birds during winter to the nearby Siju wildlife and bird sanctuary. The recovery of cerealia along with Areca catechu and Citrus pollen indicate the human activity in the region. The abundance of fungal remains, namely Meliola, Glomus, and Microthyriaceae along with degraded palynomorphs are suggestive of strong microbial activity under warm and humid conditions during sedimentation in the region. The main objective of this study is to identify the potential of bat guano for palaeoecological research and as supportive data for surface and sedimentary soil profiles in the South Garo Hills of Meghalaya. The palynodata from the bat guano of the Siju Cave provides a useful source for palaeoecological information for the South Garo Hills, where intensive natural and human-caused forest fires, heavy rainfall, and soil erosion occur every year and there is a relative scarcity of the lake, wetland, and swamp habitats that normally preserve pollen.
