Cinnamomum balansae is an endemic, rare species of tree in Vietnam, was rated level EN by IUCN, VU by the Vietnam Red Book – 2007 and classified as group IIA by Decree 32/2006/NĐ-CP. Besides its natural regeneration capacity is very limited so conservation and development for this species are facing a big challenge of seedling shortages.

The species of this family are facing tremendous pressure due to habitat degradation, overexploitation and changing environmental conditions. Therefore, while exploring the floristic diversity of NUPA, attempts were made to explore the orchid diversity, distribution patterns, nativity, endemism, threat categories, and local uses.

Sicily (Italy) hosts a “relict”, endemic population of the birds Alectoris graeca whitakeri commonly known as Sicilian Rock Partridge. In the last decades, due to the risk of restocking with other European and Asiatic species for hunting purpose, a study was carried out to investigate the potential risk of hybridisation. The mtDNA control-region and nuclear microsatellites were genotyped. Due to the importance of the species, samples were mainly characterized by feather and stool samples, and rarely by carcasses found in the environment, from year 2011 to 2012.

Climate aridization and increased anthropogenic pressure pose a severe threat to natural vegetation, including coastal plant communities. Those located in river basins of the desert zone of Central Asia are among the most vulnerable. Of the variety of ecosystems of the Ili-Balkhash region of Kazakhstan, forests dominated by a rare relict species Populus pruinosa Schrenk are of particular concern. This species occupies a very narrow ecological niche associated with river banks of the arid zone, which makes it very vulnerable to adverse natural and anthropogenic factors.

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.

Cupressus gigantea, a rare and endangered tree species with remarkable medicinal value, is endemic to the Tibetan Plateau. Yet, little is known about the underlying genetics of the unique ecological adaptability of this extremely long-lived conifer with a large genome size. Here, we present its first de novo and multi-tissue transcriptome in-depth characterization.

The precise evaluation of the conservation status of endemic and rare species is necessary in order to prevent their extinction. According to our current taxonomic revision of Turkish Salvia L., the Mediterranean and Aegean geographic regions of Turkey have 60 taxa, 32 of which are endemic (mainly local endemics), 5 of which are non-endemic rare, and the remaining 23 taxa are widely distributed.

When habitats of a rare and/or endemic species are damaged and/or fragmented by various human activities, the distribution ranges and population sizes of the species will be reduced, leaving them vulnerable to extinction at a much higher rate than other comparable species. Species that experience any of the above attributes must be given priority and monitored and managed carefully in an effort to promote genetic conservation.

Bromus psammophilus P.M.Sm., a rare endemic species, was known only from the type collection on the coastal dunes of Çukurova Delta (Adana, Turkey). Specimens belonging to the new and typical varieties of this taxon were collected from sand dunes and dune slacks where the type specimen was collected the first time.

Hard limestone, dolomite, sandstone, and granite constitute, under certain conditions, smooth-faced outcrops in desert areas of SW Asia. This habitat supports the most rare plant species in the desert including most of the desert endemics of Israel, Sinai, and Jordan.

The biology and ecology of Orchis galilaea Schltr., a species endemic to Lebanon, Palestine, and Jordan, is poorly studied, a fact that hinders present and future management and conservation efforts concerning this species. In this paper, we report findings of a field investigation that assessed the impact of altitude, population density, and plant size on the reproductive success of O. galilaea.

Oxytropis glandulosa Turcz. (Fabaceae) is a rare perennial plant endemic to Buryatia (Russia). We sequenced three intergenic spacers (the psbA–trnH, trnL–trnF, and trnS–trnG) of chloroplast DNA (cpDNA) in specimens of four populations from two geographic regions (Barguzin and Yeravna depressions) within this species range.

Menispermaceae is represented by about 70 genera and approximately 520 species. In Vietnam, it is represented by 19 genera, 50 species and two varieties, of which six species are endemic. Most species are dioecious climbers, rarely trees, shrubs, or herbs and distributed in tropical region, sometimes subtropical regions and warm temperate zones.
