Yıldız, Faruk; Aslay, Meral; Kandemir, Ali; Kaya, Ozkan
Fritillaria aurea, unlike other Fritillaria species, is a narrowly endemic species. It has a brown checkered speckled color on each tepal and also has regular yellow intense colors on the tepals. Its large bell-shaped appearance when the flower is open is one of its most striking ornamental features. However, F. aurea plant numbers are limited in their natural habitats, and their numbers are decreasing day by day; they are even confronted with the risk of extinction owing to the damage resulting from human activities. This detailed investigation of reproductive biology plays a vital role in determining the evolutionary success and survival of F. aurea, largely in determining the effectiveness of their reproductive performance. Our results indicate that the species exhibits a very low partial dichogamy and herkogamy structure, as well as self-incompatible pollination. The flowering period ranges from March to April. Average seed viability, average seed number, and seed germination were determined as 71%, 255, and 45%, respectively. The pollen viability, pollen grains, and stigma receptivity were found as 96%, 392.000, and 85%, respectively. The pollen/ovule ratio (P/O) and self-incompatibility index (SII) in the spontaneous cross-pollination were detected as 1537 and 0, respectively. Flowers of F. aurea were visited by several insect species, mostly honeybees (Apis mellifera); Bombus sp. and Vespa sp. also played a minor role in pollination. To sum up, these results not only lay a solid foundation for further reproductive biology investigations to more broadly reveal the mechanisms of F. aurea endangerment in the future but also provide a reliable theoretical basis for hybridization breeding of parents.

Sarı, İdris; Kandemir, Ali
Abstract: Genus Eryngium L. is the biggest genera of Apiaceae, which is one of the most\rwell-known families of flowering plants. Eryngium ilex P. H. Davis is one of the most\rspectacular species of the genus, represented by 27 taxa in Turkey, and its distribution is\rlimited to the Munzur Mountains in the World. No research has been found except\rits introduction to the world of science and distribution modeling of the species. In this study,\rdetailed morphological and some abiotic and biotic ecological features of the species were\rinvestigated. Climatic characteristics preferred by the species were determined by using\rbioclimatic variables and records of the species’ individuals. To determine insect visitors of\rthe species and threats to the species’ habitats, we observed by visiting two populations of the\rspecies seven times between June and September in 2013. Morphological findings obtained\rfrom 10 individuals of the species were compared with the findings of P. H. Davis’ research.\rCompared with the original description of the species, it was determined that the species\rcontains more variations than the specified morphological characters. It was found that soil\rproperties of the species’ habitat were slightly alkaline, non-saline, clayey-loamy in structure,\rhaving less humus as organic matter, and chalky or non-chalky. It has been revealed that the\rdistribution of the species highly related to the topographic structure of the habitats, according\rto results obtained from field observations. It has also been revealed that the species prefers\rharsh climatic conditions, and some visitors of the species may be harmful to it. In conclusion,\rthe species has been re-described, and some suggestions regarding its conservation have been\rmade.

Sari, İdris; Kandemir, Ali
Turkey is one of the most important temperate countries on Earth in terms of plant diversity. There is a growing interest in understanding habitat suitability and future distributions of species in the scientific world. Because climate change has impacted ecosystems with major consequences, species are shifting and declining much faster than in the past. Some global climate models used for predicting climate in the future better represent and have higher reliability for some climate types. Ferulago glareosa, which lives in Turkey, is a rare endemic plant species. In this study, we investigated current and future distributions of the species determined to be habitat-specific to lead to future studies on conservation. The Maxent model was used to map the current and future potential distribution of the species for Turkey. HadGEM2-ES and MPI-ESM-LR global climate models based on predicted future suitability of F. glareosa for 2050 and 2070 were examined. Models were constructed based on 20 presence points of the species and 2 abiotic variables. The current species distribution modeling of Ferulago glareosa predicted by the model produced very high success rates with training and test AUC values of 0.970 and 0.968, respectively. The true skill statistics value of the model (0.8245) indicated excellent model performance. In the end, we have demonstrated how predictions obtained from a highly reliable global climate model for a region’s climate could provide more dependable insights into the future distribution of narrow-spread endemic species.

In this study, secondary metabolite profiles of flower, leaf and root of Adonis paryadrica ethanolic extracts were performed by using a newly developed and validated LC-MS/MS method. For this purpose, the LC-MS/MS system was used for the quantitative and qualitative analysis of 37 phytochemicals. The main component of the flower, leaf and root extracts was the quinic acid (160, 111 and 64 mg/kg, respectively). Antioxidant activities were determined using methods such as DPPH (SC50, mg/mL), FRAP (µM TEAC), CUPRAC (µM TEAC), ABTS (SC50, mg/mL) and TPC (GAE, µg/mL). While the highest antioxidant activity value for FRAP, CUPRAC, ABTS and TPC methods was determined in the leaf part of the plant, this value was determined in the flower part for DPPH. The antibacterial effects of the plant extracts were determined by liquid microdilution and agar diffusion methods. As a result, antimicrobial effect of flowers, leaf and all sections of plant extracts were determined except plant root extracts which did not display any activity against bacteria. Antimicrobial activity of the plant flower extract was found to be higher especially against to P. vulgaris with 3.5 mg/mL MIC.

This study was designed to evaluate the phenolic compounds and the in vitro antioxidant and antimicrobial activities of Onobrychis nitida, Hedysarum cappadocicum, Ebenus laguroides and Ebenus macrophylla which are medicinal plants and endemic for the flora of Turkey. The RP-HPLC-DAD (reverse phasehigh performance liquid chromatography with a diode array detector) was used to evaluate the phenolic contents. The antioxidant properties were determined to use total phenolic content (TPC), ferric reducing antioxidant power (FRAP), and DPPH• radical scavenging activity assays. Antibacterial tests were performed against 11 different microorganisms by using the microwell dilution method. Each of the plant extracts were confirmed by bioactive assays which demonstrated a significant activity due to different chemical characteristics. Especially, rutin was the dominant component in Ebenus species with 19.434-11.808 mg phenolic/g extract. While the highest phenolic content (101.73 mg gallic acid equivalent/g extract) was observed in O. nitida, the highest FRAP value was in E. laguroides (719.09 μM FeSO4.7H2O equivalent), and the strongest DPPH degree was in the E. macrophylla extract with IC50: 69.45 μg/mL, respectively. Although plant extracts didn’t have efficient values for antimicrobial activity, the slight effect was arisen in O. nitida against B. subtilis and S. aureus. The results showed that all the extracts could be used in pharmacological or dietary applications due to their valuable properties
