“…Very recently then, increasing anthropogenic influence on ecosystems of coastal near areas might have established favourable conditions for a further range expansion. On the Istrian peninsula (Croatia), human impact on coastal ecosystems began about 5000 years ago and was described as one of the main drivers of a long-term ecological change that led to the replacement of coastal-near woods by ‘shrubland’ dominated, amongst others, by Cistus [ 49 ].…”

Cistus (Cistaceae) comprises a number of white- and purple-flowering shrub species widely distributed in the Mediterranean basin. Within genus Cistus, many taxa are subject to various taxonomic uncertainties. Cistus creticus, a prominent member of the purple-flowered clade, is a prime case of the current taxonomic troubles. Floras and databases approve different species names and utilise different or additional/fewer synonyms. Various intraspecific classification systems based on subspecies or varieties are in use. The inconsistent determination of plant material makes it difficult to compare literature regarding the phytochemical diversity and biological activities of plant material and impedes a systematic utilization of the manifold medicinal properties of C. creticus. In the present investigation, we used DNA sequence data from one nuclear region (ITS) and two chloroplast regions (trnL-trnF, rpl32-trnL) to test the intraspecific genetic diversity of C. creticus and its evolutionary relationships to the closely related C. albidus. The combined DNA data confirmed C. creticus as a rather heterogeneous species that integrates two major evolutionary lineages with clearly different genetic characteristics. The ‘Eastern Mediterranean clade’ seems to represent old and ancestral characteristics. This lineage exhibits a close relationship to the geographically distant C. albidus, expressed by very closely related ribotypes and an interspecifically shared chlorotype. The ‘Western Mediterranean clade’ is characterized by a distinctive ITS polymorphism (co-occurring paralogous ribotypes) and more distantly related chlorotypes. The formation of the genetically complex ‘Western Mediterranean clade’ seems to have involved hybridization and recurrent formation or migration movements.

“…Additionally, a decrease in temperature was not commonly featured across the whole region. Speleothem records from the eastern Adriatic insular caves Strašna peć (Dugi otok Island) (Lončar et al, 2019) and Mala špilja (Mljet Island) (Lončar et al, 2017) both point to dry environmental conditions around 4.2 ka (Figure 6), as well as some other regional proxies from the cores from Busuja Bay in Istria (Kaniewski et al, 2018), Lake Vrana (Cres Island) (Schmidt et al, 2000) and Bokanjačko blato in North Dalmatia (Ilijanić et al, 2018). Although the climate type of the NG region does not fully correspond to the Mediterranean climate of Bini et al (2019) (based roughly on the reach of the olive tree), the NG speleothem clearly recorded this sudden anomaly.…”

Holocene hydroclimate changes in continental Croatia recorded in speleothem δ¹³C and δ¹⁸O from Nova Grgosova Cave

et al. 2021

We present the first stable isotope (δ13C and δ18O) speleothem record from continental Croatia retrieved from two coeval stalagmites from Nova Grgosova Cave. U-Th dates constrain the stalagmite growth history from 10 ka to the present, revealing coeval growth between 7.8 and 5.6 ka. We interpret δ18O as an autumn/winter hydrological proxy related to changes of vapor source, precipitation amount, and/or seasonal rainfall distribution, while δ13C predominantly responds to spring/summer vegetation status and soil microbial activity. We identify several centennial to millennial-scale hydroclimate oscillations during this period that result from multiple forcing factors. Along with amount and source effect, it appears that some centennial variations were governed also by seasonal moisture balance. From 9.2 to 8.8 ka BP, the local environmental setting was characterized by enhanced vegetation activity, while during the 8.2 ka event the main feature was a change in precipitation seasonality. The most prominent change, identified in both δ13C records, is a sudden decline of vegetation and soil biological activity around 7.4 ka, indicating a precipitation decrease at a time of maximum plant growth in spring and summer and likely also reduced precipitation in autumn and winter. Although small in magnitude in these speleothems, a peak in δ18O and δ13C values at 4.3–4.1 ka suggests that both summer and winter conditions were substantially drier during the 4.2 ka event, in accordance with increased Mediterranean aridity and consistent with other global climate changes reported at this time. Compared to the present North Atlantic Oscillation (NAO) influence, we assume that millennial Holocene NAO-like variations were persistent through the Holocene via their effect on modifying local/regional air temperature, vapor origin, and inter- and intrannual precipitation distribution. Anthropogenic deforestation, which was the first major human impact on the environment during the Neolithic agricultural revolution, is excluded as a leading factor in δ13C variability since the first sedentary settlements were established further to the east in more arable locations along river valleys. However, the impact of intensive mining around the cave site during the last millennium is evident, with substantial deforestation driving an increase in δ13C.

“…The term karst itself derives from the impact of early forest clearance and farming on rugged limestone terrain in the northern Dinaric coastal region (Ford and Williams, 2007). Significant human impacts on ecosystems of the eastern Adriatic coast began already around 5000 years ago (Kaniewski et al, 2018). The process of transformation of the originally wooded but stony regions into farmland continued throughout the classical Greek times (Gams, 1991).…”

This study provides a reconstruction of the 1.5 ka palaeoenvironmental evolution of the small, and presently dry, Milna valley on the island of Vis. Sediments from the valley were studied using multi-proxy approach, applying sedimentological, mineralogical, petrological, anthracological, malacological, 14 C and land cover analyses, in regard to climatic, vegetation, and hydrological changes. The mineral composition of the siliciclastic detritus from the Milna valley points to the Dinaride Ophiolite Zone in Bosnia as its dominant source of origin, eroded by the Neretva River, and deposited in the form of alluvial sediments in the Central Adriatic area. However, Cetina and Drin Rivers may have also contributed some of the sediments. Regional aeolian resedimentation of the material occurred during Pleistocene, which later accumulated and became preserved in the Milna valley. Beside the Dinaride Ophiolite Zone, part of the mineral composition is influenced by minerals from the Alpine region and by neutral to basic volcanism, probably of Italian origin.
