Response of black pine (Pinus nigra) in southwestern Anatolia to climate change

Global climate change is one of the most critical challenges facing natural ecosystems. As sedentary organisms, plant communities are especially vulnerable, with climate change significantly impacting their development, productivity, and distribution. This study focuses on modelling and mapping the potential distribution of black pine (Pinus nigra) within the Antalya Regional Forest Directorate under the SSP1 2.6 climate scenario for the years 2040, 2060, 2080, and 2100. The MaxEnt modelling method, combined with the HadGEM3-GC31-LL climate model from WorldClim, was used to assess the impact of climate change on black pine. The current distribution model results showed “good” predictive performance, with AUC values of 0.855 for training data and 0.851 for testing data. Key variables influencing the model included precipitation during the wettest quarter, annual precipitation, maximum temperature of the warmest month, and elevation. Projections indicate that the black pine’s distribution will shrink by 2040, become increasingly fragmented by 2060, and decline further by 2080, with near-total disappearance by 2100. In conclusion, this study highlights the urgent need for adaptive management strategies to address the effects of climate change on black pine forests.

Relationships between site index modeling of crimean juniper and habitat factors

The aim of this study is to examine the relationships between height growth and some site factors of Crimean juniper in southwestern Anatolia. The data was collected from 130 sample plots selected from 10 districts in western Anatolia. The age and height of the Crimean juniper were measured in each sample plot. Surface soil samples collected from each sample plot were analyzed for pH, organic matter, carbonate content, texture, stoniness, available water capacity, wilting point, and field capacity. All site index values were calculated at a standard age of 100 years old. Spearman and Pearson correlation analyses were used to determine the relationships between plus tree and site factors. According to Spearman's correlation analysis, the site index showed a negative relationship with limestone. According to the results of the Pearson correlation analysis, the numerical variables LATTUD, SLOPE, SURSTON, and HINDEX had a 1% relationship with the site index, and RINDEX had a 5% relationship. Once the binary relationships had been determined, the multivariate relationships were modelled using generalized additive models. The best site index model was obtained using a generalized additive model 1 (R = 0.63), including latitude, longitude, altitude, slope, and stoniness.

Micropropagation and cryopreservation of the rare endemic Colchicum figlalii germplasm

BACKGROUND: The natural population of Colchicum figlalii (Varol) Parolly & Eren grows in a narrow area of serpentine rock clearings at an altitude of 1900-2100 m in Southwestern Anatolia (Sandras Mountain, Mugla, Turkey). The species is regarded as endangered according to the IUCN Red List Categories. OBJECTIVE: To develop an optimum procedure for in vitro propagation and cryopreservation of germplasm of this rare endemic. MATERIALS AND METHODS: A total of 281 bulbs were used as in vitro culture starting material and after surface sterilization, clean material was obtained from 157 of them. Woody Plant Medium (WPM), Olive Medium (OM), and Murashige and Skoog medium (MS) were used for in vitro culture establishment. RESULTS: The maximum regeneration rate (˜67.3%) was obtained after four weeks of incubation on OM. The calli were successfully induced by using OM supplemented with 10.7 μM NAA from leaves of in vitro grown C. figlalii bulbs. A PVS2-vitrification procedure was used for cryopreservation of C. figlalii callus tissue. After cryo-storage, the best result for regeneration (66.7%) was obtained from calli treated with PVS2 for 75 min before plunging into liquid nitrogen. All rooted seedlings derived from cryopreserved calli were successfully acclimatized to greenhouse conditions. CONCLUSION: This study is an effective reference for future long-term conservation of similar species that are difficult to cryopreserve.

Screening the antimicrobial, cytotoxic and hemolytic effects of skin-parotoid gland secretions of 13 taxa from six species and one hybrid population of Anatolian endemic Lycian salamanders (Genus: Lyciasalamandra)

Background and purpose: The diverse bioactive content in the skin and parotoid glands of amphibians makes them unique and highly potential sources for pharmacological developments. The main aim of the study is to determine the total protein amounts, in vitro cytotoxicities, antimicrobial activities and hemolytic effects of skin-parotoid secretions of these endemic Lycian salamanders (Genus: Lyciasalamandra). Materials and methods: Lycian salamander specimens of 13 taxa from six species and one hybrid population are collected from southwestern Anatolia. Skin-parotoid secretions were obtained, clarified, supernatants snapfrozen then lyophilized. Total protein amounts were determined by BCA assay kit. The cytotoxicity was determined on eight different cell lines (one healthy and seven cancerous) using MTT assay. The antimicrobial activity was assesed using 11 different microorganisms (nine bacteria and two yeast) from six genus by MIC method. Hemolytic effects were measured on rabbit red blood cells. Results: Lycian salamanders’ skin-parotoid gland secretions showed variable cytotoxic effects on all cell lines with IC50 values from 5.41 ± 0.17 μg/ml to ineffective. MIC results of antimicrobial activity tests were also variable and from 3.9 μg/mL to non-effective. Studied skin-parotoid secretions have no hemolytic activities on rabbit red blood cells at concentrations of 0.5, 5 and 50 μg/mL. Conclusions: Skin-parotoid gland secretions of Anatolian endemic Lycian salamanders have sufficient and remarkable therapeutic potential to be candidate sources of natural and biologically active substances for novel drug discoveries.

Divided Selves in Exile: Third Space in Louis de Bernières’ Birds Without Wings

Set in the early 20th century, Louis de Bernieres’ novel Birds Without Wings focuses on the divided identities negatively influenced by wars, exile, and migration in southwestern Anatolia just before the decline of the Ottoman Empire and foundation of Republican Turkey. Based on the decision of population exchange, a great number of non-Muslim people were deported to a foreign land (Greece), away from the newly defined borders of the new Turkish Republic. In his novel Birds Without Wings, Louis de Bernières scrutinizes this social phenomenon and questions the significance and validity of the notions such as race, religion, ethnicity or language in the nation building process. The author deplores the loss of multicultural lifestyle in a utopian, idyllic Anatolian town with the displacement of Greek and Armenian residents. The multicultural structure of society penetrates into the formal and narrative features of the novel, such as multiplicities in viewpoints, a mixture of genres, different languages and the use of nicknames for protagonists. Intercultural encounter provokes hybridity and leads to the emergence of multiplicities in society. However, the exchange of population puts an end to the long-established multicultural society structure, a dynamic cultural exchange and negotiation. The use of multiple voices, multiple characters, narrative techniques, and multiple languages in fact celebrates the hybridity and plurality of worlds throughout the novel. Homi K. Bhabha’s concept of the in-between third space challenges the formation of cultural identity in hybrid societies, simultaneously embracing multiplicities, pluralities, and hybridity. The writer signals to the existence of such a harmonious heterogenous society in Anatolia in the past time and laments for the loss of such an idyllic lifestyle reigned by mutual love, respect, tolerance and cooperation. The purpose of this paper is to interrogate how Bhabha’s conceptualisation of “third space” finds a place in the lives of divided selves in Louis de Bernières’ Birds Without Wings and to demonstrate how it deconstructs the binary thought and essentialist identity in intercultural encounters.

Ancient mitogenomes from Pre-Pottery Neolithic Central Anatolia and the effects of a Late Neolithic bottleneck in sheep (Ovis aries).

Occupied between ~10,300 and 9300 years ago, the Pre-Pottery Neolithic site of Aşıklı Höyük in Central Anatolia went through early phases of sheep domestication. Analysis of 629 mitochondrial genomes from this and numerous sites in Anatolia, southwest Asia, Europe, and Africa produced a phylogenetic tree with excessive coalescences (nodes) around the Neolithic, a potential signature of a domestication bottleneck. This is consistent with archeological evidence of sheep management at Aşıklı Höyük which transitioned from residential stabling to open pasturing over a millennium of site occupation. However, unexpectedly, we detected high genetic diversity throughout Aşıklı Höyük's occupation rather than a bottleneck. Instead, we detected a tenfold demographic bottleneck later in the Neolithic, which caused the fixation of mitochondrial haplogroup B in southwestern Anatolia. The mitochondrial genetic makeup that emerged was carried from the core region of early Neolithic sheep management into Europe and dominates the matrilineal diversity of both its ancient and the billion-strong modern sheep populations.

Predicting the effect of climate change on the geographic range of the Mediterranean relict tree Liquidambar orientalis Mill

Climate change is anticipated to pose a significant danger to the habitats and spatial distribution of species in the Mediterranean region throughout the present century. The primary objective of this study was to predict the future geographic range of Liquidambar orientalis, commonly known as the oriental sweetgum under different climate change scenarios. This species is a relict riparian Mediterranean plant originating from the southwestern Anatolia region and Rhodos Island in Greece. To gain insights into the potential effects of climate change on the range of L. orientalis in the future, I used an ensemble modeling approach of species distribution models based on the shared socioeconomic pathways (SSP1‐2.6 and SSP5‐8.5 for the years 2035, 2055 and 2070). The models suggested that the level of precipitation during the wettest month has a crucial role in determining the occurrence of the oriental sweetgum tree. Future projections indicate that the oriental sweetgum will significantly contract its native distribution range due to warming and declining precipitation levels. The population of L. orientalis has previously undergone a decrease as a result of anthropogenic activity. Therefore, it is imperative to augment the degree of urgency in conservation endeavors for the oriental sweetgum species against the ramifications of human‐induced actions and the persistent effects of climate change.

The upper crustal thermal structure of the Cameli Basin and its surroundings (SW Anatolia, Türkiye) by using the fractal-based centroid method of aeromagnetic data and its relationship with earthquakes occurring in the region

The Cameli Basin and its surroundings are located in southwestern Anatolia, Türkiye, and are one of the tectonically active regions in western Türkiye. The Curie point depth of continental crust can help us to determine the regional tectonic and geothermal structures. The aeromagnetic magnetic data of the study region were used to determine the Curie Point Depth estimates. The fractal-based centroid method is used for this purpose. The fractal approach removes the effect of fractal magnetization in the power spectrum. The depth to the bottom of the deepest magnetic sources in the study region ranges between 6.9 and 14.05. The estimated thermal gradient varies from 41.28°C/km to 89.23°C/km and the average value is 58.59°C/km (580°C for magnetite). The distributions of earthquakes are compatible with NW-SE trending estimated Curie depth anomalies. Interpretation indicates that the depth to the Curie isotherm is considerably shallower than the Moho depth.

Phylogeography of Dolichophis Populations in the Aegean Region (Squamata: Colubridae) with Taxonomic Remarks

In this study, we investigate the phylogeographic patterns of Dolichophis species in the Aegean region, aiming to elucidate their genetic diversity and putative historical colonisation routes through mitochondrial and nuclear DNA data. Our findings revealed distinct phylogeographic patterns: D. caspius exhibited a higher level of haplotypes within two shallow mitochondrial lineages, contrasting with D. jugularis, which displayed lower genetic variability in the area. Additionally, we identified evidence showing possible human-mediated historical translocation of D. caspius populations to Karpathos from the Balkans mainland. The mitochondrial variability in D. jugularis remained relatively uniform across southwestern Anatolia and Dodecanese, except for Rhodes Island. The evidence from mitochondrial and nuclear data confirming the previously described morphological differentiation of the Rhodes snakes, and thus the name D. j. zinneri Cattaneo, 2012, described on the island, could be applied to this isolated population. This result addresses the first genetic view on the long-standing taxonomic uncertainties regarding the subspecies status of Rhodes D. jugularis. Our results also raise questions regarding possible historical hybridisations between D. caspius and D. jugularis in the Dodecanese islands, prompting the need for further investigation using extensive field studies and genomic approaches. Ultimately, the Aegean islands, particularly Kos and Rhodes, seem to be important sites for the evolution of these colubrid snakes and their historical dynamics.

Growth form, regeneration mode, and vegetation type explain leaf trait variability at the species and community levels in Mediterranean woody vegetation.

Leaf traits are good indicators of ecosystem functioning and plant adaptations to environmental conditions. We examined whether leaf trait variability at species and community levels in Mediterranean woody vegetation is explained by growth form, regeneration mode, and vegetation type. We studied several plant communities across five vegetation types - semi-closed forest, open forest, closed shrubland, open shrubland, and scrubland - in southwestern Anatolia, Türkiye. Using linear mixed models, community-weighted trait means, and principal component analysis, we tested how much variability in three leaf traits (specific leaf area, leaf thickness, and leaf area) is accounted for species, growth form, regeneration mode, and vegetation type. Despite a large amount of leaf trait variability both within- and among-species existed, functional groups still accounted for a significant part of this variability. Resprouters had higher SLA and leaf area and lower leaf thickness than non-resprouters. However, further functional separation in regeneration mode, by considering the propagule-persistence trait and the seed bank locality, explained leaf trait variability better than only resprouting ability. Although no consistent pattern was observed in three leaf traits in the growth form, we found evidence for the difference in SLA and leaf thickness between shrubs and large shrubs, and subshrubs had smaller leaves than other growth forms. Vegetation type also accounted for a substantial amount of leaf trait variability. Specifically, plant communities in closed habitats had larger leaf area than open ones, and those in scrublands had higher SLA, lower leaf thickness, and lower leaf area than other vegetation types. Climate and phylogeny had limited contribution to the results obtained, with the exception of a significant phylogenetic effect in explaining the differences in SLA between resprouters and non-resprouters. Our results suggest that multiple drivers are responsible for shaping plant trait variability in Mediterranean plant communities, including growth form, regeneration mode, and vegetation type.

The comparison of land cover change and erosion-deposition patterns during the Early Bronze Age-I (ca. 5100-4700 cal. BP) in Eastern and Southwestern Anatolia

Land use in archaeological societies has important consequences for ecosystemic changes in the long-term, which directly affect the sustainability of the economy and socio-political organization. In the Near East; socio-political organization, mode of production, and land use patterns diversified spatio-temporally during the Early Bronze Age-I (ca. 5100–4700 cal. BP) when socially complex entities emerged across the region. During this transformative phase, Anatolia witnessed polities of varying levels of organization and modes of subsistence, all of which translate into diverse land use patterns. This research focuses on the results of agent-based modeling to simulate the long-term impacts of land use/land cover change at two major Early Bronze Age sites; Arslantepe (ca. 5100–4700 cal. BP) in Eastern Anatolia and Hacılar Büyük Höyük (ca. 5100–4900 cal. BP) in Southwest Anatolia. Arslantepe and Hacılar Büyük Höyük are situated in different environments (i.e., climate and vegetation), and show different levels of social organization, and economies. Comparing the land use patterns of these two contemporary but otherwise different polities presents important results in terms of our understanding of how land use patterns diversify and what their ecological results have been in the long term.

Advancing low-flow quantile estimation: The role of areal scale factor (ASF) and annual flow–duration curves

Abstract Estimating the streamflow corresponding to a particular probability is of great importance in many hydrological studies, such as determining hydroelectric water potential, assessing water quality, and investigating sedimentation and drought. This paper aims to effectively estimate low-flow quantiles since hydrologic droughts motivate the study. The study illustrates a methodology, where droughts are characterized by the lower part of the flow–duration curve (FDC), and offers a perspective estimating low-flow quantiles related to the basin characteristics. Low-flow quantiles are derived both from traditional FDCs curves and median annual FDCs (AFDCs). As an innovation, the concept of areal scale factor, which represents a scaling ratio between the basin area and flow quantiles, was introduced. Unlike many other parametric approaches, this study models the streamflow quantiles depending on the basin characteristics instead of the parameters in the analytical equation of FDCs. The methodology was evaluated for the Western and Southwestern Anatolia regions in Turkey. The outcomes were compared for two types of FDCs in two regions. The approach gave similar results for both study regions. AFDCs provided a distinct advantage over traditional FDCs, especially for low-flow quantiles, due to the superiority of AFDCs in estimating streamflow quantiles of intermittent streams.

Microgeographic speciation in a complex of Anatolian bush crickets facilitated by fast evolution of reproductive isolation.

Identifying the drivers of microgeographic speciation (i.e., speciation over small, local geographic scales) is key to understand the origin of speciose groups. Here, we use genomic data to infer the demographic processes underlying diversification in Poecilimon luschani (Orthoptera: Tettigoniidae), a species complex belonging to the most diverse genus of bush crickets from the Mediterranean region (>170 taxa) that comprises three recognized subspecies with small allopatric distributions in the topographically complex Teke Peninsula, southwestern Anatolia. Phylogenomic reconstructions that include all other taxa within the species group confirmed that subspecies of P. luschani originated from a common ancestor during the Pleistocene, supporting recent (<1 Ma) diversification within a small geographical area (ca. 120 × 80 km). Genetic clustering analyses corroborated the distinctiveness of each subspecies and the cohesiveness of their respective populations, with abrupt genetic discontinuities coinciding with contemporary range boundaries. Indeed, our analyses uncovered the presence of two sympatric cryptic sister lineages that diverged <300 ka ago and do not admix despite being co-distributed. Collectively, these results support that all lineages within the complex represent independently evolving entities corresponding to full-fledged species. Statistical evaluation of alternative models of speciation strongly supports a scenario of divergence in isolation followed by a period of limited gene flow during the last glacial period, when all lineages experienced marked expansions according to demographic reconstructions. Our study exemplifies how localized allopatric divergence and fast evolution of reproductive isolation can promote microgeographic speciation and explain the high rates of endemism characterizing biodiversity hotspots.

Morphological and functional trait divergence in endemic fish populations along the small-scale karstic stream

BackgroundOrganisms with broad distribution ranges, such as fish, often exhibit local ecological specializations based on their utilization of food and habitat. Populations of species that live in different habitat types (lotic vs. lentic) show morphological variations. However, the phenotypic differences of endemic fish populations in a small karst river basin under anthropogenic pressure are still not fully understood. In this study, the functional traits and morphological variations of the populations of endemic Pseudophoxinus antalyae Bogutskaya, 1992, in the Düden Stream basin, which is subjected to various anthropogenic disturbances and habitat types in southwestern Anatolia of Türkiye, were examined using linear measurements and geometric morphometric analysis.ResultsDifferences have been identified in functional traits, particularly those related to food acquisition between populations. Results of both univariate and multivariate analyses revealed significant differences in body shape and size among populations living at sites along the stream with different habitat and environmental characteristics.ConclusionsThe reason for these differences determined in the morphology and traits of the populations may depend on habitat types, ecological, or environmental, and obstruction of gene flow. More detailed studies are needed to explain the mechanisms (genetic and ecological) that cause these differences.

Evolution of a Medieval Castle Town and Its Landscape in the Southwestern Anatolia

ABSTRACTThe objective of this paper is to develop a framework for understanding the archaeological sites composed of the remains and traces of castle towns and evaluating these sites together with their landscapes with a retrospective focus. A case study approach was undertaken with a focus on Kale Tavas (Tabae) in the Southwestern Anatolia. The scope of the Historic Landscape Characterisation was adapted to characterise the remains and traces of the castle town together with its landscape. Site survey at different scales, archive research, and in-depth interviews were used to acquire data. Our results suggest the related conservation boundaries should be determined not only considering the citadel walls but also the natural context that had contributed to the evolution of the castle town. For Kale Tavas, heritage management should be planned by considering the values of the historical landscape and the factors that threaten them, as this study shows.

Bioecology and Systematic of Scorpions in Southwestern Anatolia Region (Arachnida: Scorpiones)

Abstract&#x0D; In this study, scorpion fauna of six provinces in Southwestern Anatolia Region (Antalya, Aydın, Burdur, Denizli, Isparta and Muğla) of Turkey was studied and 5 species, 1 subspecies in 4 genera belonging to 3 families were recorded. Examined specimens were collected between May 2006 and September 2011 from several provinces of research field in Southwestern Anatolia Region. As result of field trips 342 specimens were collected. Besides, some museum materials which were previously collected were used. At the end of the studies; it was determined that Neocalchas gruberi, Euscorpius carpathicus (=E. honazicus, E. sultanensis, E. arikani, E. avcii, E. lycius, E. gocmeni), Iurus kinzelbachi, Protoiurus kadleci, P. kraepelini and Mesobuthus gibbosus anatolicus species are distributed in Southwestern Anatolia Region of Turkey. Among these samples Neocalchas gruberi species was recorded from Isparta province, Protoiurus kraepelini species was recorded from Isparta and Denizli provinces for the first time. In this study, the systematic and faunistic information of determined species were cited, besides ecological and biological field trip notes were recorded.

Paleobiodiversity and paleoenvironments of the eastern Paratethys Pleistocene lacustrine-palustrine sequence in the Baklan Basin (SW Anatolia, Turkey)

The Lower-Upper Pleistocene sedimentary record of the Baklan Basin, a long-lived continental half-graben basin in SW Turkey, is characterized by shallow lacustrine and palustrine deposits. The paleoenvironmental changes recorded in the basin succession allow for a multiproxy approach in reconstructing the paleoclimatic, paleoecological, and paleobiogeographical evolution of southwestern Anatolia during the Early-Late Pleistocene. Based on sedimentological, paleontological, and geochemical data, three main types of depositional intervals have been identified, corresponding to different phases of a lake expansion cycle: The first interval is characterized by the perennial shallow lake environment (PSL deposits), which represents the very early stage of the Early Expansion System Tract (VEEST). This suggests a very early stage of lake transgression in arid climate conditions. The second interval is represented by the palustrine carbonate lake center environment (PLC deposits), which corresponds to the late stage of the Early Expansion System Tract (LEEST). This indicates a late early stage of lake transgression in semiarid to subhumid climates. The third interval is marked by the palustrine lake margin environment (PLM deposits), which represents the Late Expansion System Tract (LEST) under humid conditions.The Lower-Upper Pleistocene successions of the Baklan Basin provide an excellent example of lacustrine and palustrine deposition in a laterally extensive, low-gradient, shallow lake system in the semi-isolated Pontocaspian freshwater to slightly brackish water (oligohaline-low mesohaline) long-lived lake. The presence of Pontocaspian ostracod and mollusc faunas in the studied successions indicates that the largest major Caspian transgression around 2.6 millon years ago extended to SW Anatolia. The studied successions represent a rich archive of landscape, climate, and biotic development in the eastern Paratethys region during the Early-Late Pleistocene. The biogeographic signature of fossil faunas (mammals, ostracods, molluscs, and fishes) and floras (Characeae) is predominantly modern Palearctic and Holarctic, with a minor amount of endemic Pontocaspian elements. This study presents the Pleistocene Pontocaspian species of the Anatolian lakes that may have served as refugia for the Palearctic taxa during adverse time intervals. Consequently, this study shows that Lower-Upper Pleistocene lacustrine to palustrine sedimentation in the Baklan Basin has been controlled by the combination of tectonics, climate changes, and the largest major Caspian Sea transgression. The findings of this study could be used to evaluate the impact of similar allocyclic factors on the sedimentological, hydrological, and geochemical development of other intermontane lake basins.

Who were the Lelegians? Interrogating affiliations, boundaries and difference in ancient Caria

AbstractWho were the Lelegians? Ancient Greek and Latin texts refer to the Lelegians as an indigenous people, locating them in southwestern Anatolia in a region known in historical times as Caria. Yet attempts to find evidence for the Lelegians ‘on the ground’ have met with questionable success. This paper has two aims. First, it provides an up-to-date picture of the archaeology of ancient Caria and shows that there is little indication of distinctly ‘Lelegian’ forms of material culture during the first millennium BCE. Second, it juxtaposes archaeological evidence with the development of the Lelegian ethnonym and suggests that the idea of a distinct Lelegian identity was retrospectively constructed by the Carians to fulfil the role of an imaginary ‘barbarian other’. This happened in the late Classical and early Hellenistic periods, a time of intensified Carian ethnogenesis, and was a process that responded to and made creative use of earlier Greek knowledge traditions. Finally, this paper argues that a later horizon of Lelegian imagining occurred in modern scholarship of the 19th and 20th centuries. Who, then, were the Lelegians? This article proposes that they were an imaginary people, invented and reinvented over the centuries.

An assessment of the herpetofauna of the Oriental Sweetgum forests in southwestern Anatolia, Turkey

&#x0D; &#x0D; &#x0D; &#x0D; Oriental Sweetgum (Liquidambar orientalis) is a threatened tree species restricted to Rhodes Island (Greece) and southern Anatolia (Turkey), best known for its rare riparian forests. These small patches of forests are severely fragmented and scattered, and are rarely found in southwestern Turkey. Based on field sampling and data compilation, we performed an assessment of the herpetofauna in these forests in southwestern Turkey during the spring of 2019 and 2021. Sampling was carried out using a line-transect method in 13 forests with various habitats, resulting in data at the community and population levels. Sixteen families, including 26 amphibian and reptile species (four anurans, four turtles, nine lizards, and nine snakes), were recorded from these unique forests, based on 1440 individuals. Twenty-two species were recorded for the first time from these forests; in addition, Emys orbicularis and Elaphe sauromates were recorded for the first time from the region. Richness in the forest patches, habitat use by the recorded species, and interspecific interactions are discussed to explain the conspicuous patterns observed in the species distributions. The unique distribution pattern of Phoenicolacerta laevis among the existing forest patches represents the most prominent finding, with implications for a recent introduction. The fossorial species Xerotyphlops vermicularis, Blanus strauchi, and Eryx jaculus are unlikely to occur in the Oriental Sweetgum forest due to annual flooding. The data obtained during this study will be transferred to the Oriental Sweetgum forest conservation action plan (2019–2024) as part of the biodiversity monitoring tools for use in the long-term conservation of these forests.&#x0D; &#x0D; &#x0D; &#x0D;
