Up to now, it has been only known from the type locality (Samsun /Ladik). This research intends to define the global conservation status and strategies of locally distributed endemic P. samsunicum which has been confronted with the danger of extinction due to anthropogenic effects in recent years. In this research, we did extensive field studies and collected all needed data for determining the precise conservation status of P. samsunicum. We reported nine additional populations from Upper Tersakan valley, where the Mediterranean climate is dominant, and the size of populations, altitude, coordinates, habitat types, and the threats it faces in each locality were given. GeoCAT analyses at global levels indicate the grade of occurrence 21.609 km2 and area of occupancy 10.094 km2 and there could be an inferred decline due to habitat loss and fragmentation of the original population, suggesting local endemic species might be classified as CR, based on criteria B1ab (i, ii, iii) + 2ab (i, ii, iii) in the Red List categorization. Its parts are also consumed by local people due to its medicinal features. For in-situ conservation, phenological life history and detailed ecological studies, as well as population monitoring and ex-situ conservation studies should be continued together. Establishing cooperation between universities, research institutes, and local management authorities is strongly needed for long-term monitoring of population size, distribution, overgrazing, and public awareness.","PeriodicalId":39239,"journal":{"name":"Hacquetia","volume":"21 1","pages":"197 - 209"},"PeriodicalIF":0.5,"publicationDate":"2022-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42266351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on their analysis and comparison with previously described similar (alti)montane-subalpine beech communities we classified most of the relevés into the association Polysticho lonchitis-Fagetum and its new subassociations ericetosum carneae, cardaminetosum trifoliae, luzuletosum niveae, luzuletosum luzuloidis, calamagrostietosum variae, allietosum victorialis, adoxetosum moschatellinae, stellarietosum nemorum and several new variants. The altitude of the studied stands is predominantly 1400 to 1550 m (the upper line is at 1660 m); they occur at all aspects, frequently on steep and very steep slopes, mainly on limestone and dolomite limestone, the predominant soil type is rendzina.

(Asteraceae) is a species with high invasiveness capacity in Ukraine, especially in the Steppe zone. The first data on the finding of escaped plants in Europe were recorded in the 40’s of the last century. There were three naturalization centres in Ukraine, from where the species began to spread. In the secondary range in Ukraine, G. squarrosa is characterized by high levels of seed productivity and germination, variable modes of dispersal, wide ecological and coenotic amplitudes and CSR-strategy. The trend continues with the spread of the species in western, north-western and northern directions, and today more than 300 localities confirming this trend are already known. In the past 20 years, 92 new localities have been recorded. G. squarrosa is a transformer, widespread in the southern regions of the Steppe zone. As a result, new plant communities are formed. In general, this species is recorded in communities of five vegetation classes. In terms of ecological indicators, the optimum of the species is in the Steppe zone. It can be predicted that, due to the potential ability of the species to adapt and under the influence of climatic change, there is a higher probability that the species will spread in the future in northern and western directions. The condition for such an expansion is disturbance of meadow-steppe fringe xeromesic communities, with decreased coenotic competition.","PeriodicalId":39239,"journal":{"name":"Hacquetia","volume":"20 1","pages":"263 - 272"},"PeriodicalIF":0.5,"publicationDate":"2021-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43907428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
