Opis:
The mycorrhizal status of 24 plant species considered as endemic, endangered in Poland and included in the IUCN Red List of Threatened Plants is reported. Selected plants and rhizosphere soil samples were collected in the Tatra Mts (Western Carpathians). Individuals of seriously threatened taxa were obtained from seeds and inoculated with available AM fungal strains under laboratory conditions. AM colonisation was found in 16 plants; 9 species were of the Arum-type, 4 - Paris and 3 taxa revealed intermediate morphology. The mycelium of the fine endophyte (Glomus tenue) and dark septate fungi (DSE) were observed in the material collected in the field. 20 AMF species (Glomeromycota) found in the rhizosphere of the investigated plants were reported for the first time from the Tatra Mts. The results provide information that might be useful for conservation and restoration programmes of these species. Application of AMF in active plant protection projects is discussed.

Opis:
Amorphophallus titanum niezwykle rzadko obserwowany, endemiczny gatunek Sumatry, jest byliną wykształcająca jeden z największych kwiatostanów świata. Osiągająca ok. 3 m wysokości kolba i ujmująca ją purpurowa pochwa kwiatostanowa, skutecznie wabią zapylające roślinę chrząszcze, błonkówki oraz muchówki, które zwiedzione intensywnym zapachem padliny, ciepłem wydzielanym przez kwiatostan i jego barwą, kierują się ku znajdującym się w jego wnętrzu kwiatom. Mimo zadziwiających rozmiarów dziwidła olbrzymiego, jego biologia nie została dobrze poznana, a powierzchnia okołorównikowych lasów dwuskrzydlcowych Azji Południowo-Wschodniej, w których znajdują się jego nieliczne, naturalne stanowiska, z roku na rok kurczy się. Deszczowe lasy Indonezji i Malezji, będące jednym z głównych centrów różnorodności biologicznej na świecie, wycinane lub wypalane są bowiem pod plantacje olejowca gwinejskiego (Elaeis guineensis), które w samej Indonezji zajmują już ok. 7,7 mln ha.
Amorphophallus titanum, an extremely rare, endemic Sumatran species, is a perennial plant which forms one of the largest inflorescences in the world. Reaching up to approx. 3 m in height, the spadix is surrounded by a purple flower sheath which attracts the pollinators - beetles, hymenoptera and flies. Those, deceived by an intense scent of carrion emitted by the flowers and also by its colour, are lured to the flowers hidden inside the spadix. Despite its remarkable size, A. tutanum's biology has not been well known. The equatorial area of Dipterocarpaceae forests in SE Asia, which is the natural habitat of A. titanium, is dwindling. The Indonesian and Malay rainforests, ones of the main biodiversity hotspots in the world, are being cut and burnt down in order to establish African oil palm (Elaeis guineensis) plantations, which only in Indonesia cover an area of approx. 7,7 mln ha.

Opis:
New nuclear microsatellite markers (SSRs) were developed for Aesculus hippocastanum, a relict tree species from the Balkan Peninsula. The development of microsatellites was done using the Illumina MiSeq PE300 platform. Out of a set of 500 SSRs designed, a subset of 13 loci was tested using 290 individuals from seven natural populations. Twelve species-specific loci were polymorphic. The number of alleles per locus ranged from 2 to 17 and expected heterozygosity from 0.089 to 0.800 with a mean value of 0.484. The population of Kalampaka had the lowest value of allelic richness (2.63) and gene diversity in comparison to the remaining populations. STRUCTURE analysis confirmed isolation of population Mariolata from the southern edge of the species range and genetic similarity among populations from the Pindos Mts. Additionally, the utility of new SSRs in 29 individuals from nine other Aesculus taxa was tested. Eleven markers gave polymorphic products for all tested species. For 24 individuals, a high-quality product was obtained for each marker. Results confirmed the utility of specific markers for future population genetics studies.

Opis:
Astragalus nitidiflorus is an endangered legume endemic to the southeast of the Iberian Peninsula. This species develops symbiotic relationships with N-fixing bacteria. However, the problem of isolating its rhizobia has not been solved. Because poor N fixation in plants can be corrected by fertilization, the effect of N-P-K fertilizers on growth, leaf chlorophyll and mineral ions was studied. Plants of A. nitidiflorus were grown in 100%-substrate with different N-P-K fertilizer rates (mg l–1): 1-1-8 (S0), 69-29-35 (SL), 144-43-131 (SM) and 245-58-235 (SH). A treatment with substrate plus soil from the natural habitat and no fertilizers (T0) was included. The reference foliar contents of N, P and K were 42.5, 3.5 and 36.5 mg g–1, respectively. Although the species did not form root nodules when grown in substrate, T0 plants produced active nodules that allowed the plants to grow properly without fertilization. In the absence of nodules, both N fertilization (~144 mg l–1) and Fe fertilization (>12 mg l–1) are vital, as is, to a lesser extent, K fertilization (~75 mg l–1 K2O). The S0 and SL reduced leaf chlorophyll, while SM prevented its degradation.

Opis:
In the mountains of the north-central Sicily (Italy), a small and isolated population of Sicilian fir (Abies nebrodensis) has survived to the present day. It is the most unique species of the Sicilian flora, not only because of its taxonomic position, but mostly because of its endemic and relict status and the serious risk of extinction. The single natural population of this extremely rare species is currently represented by only 30 mature individuals scattered over a small area in the Madonie Mountains. This species has experienced intensive population decline since the end of the 17th century, and its situation became extremely critical in the first decades of the 19th century due to deforestation and overgrazing. Consequently, Sicilian fir was considered to be extinct about three decades before being rediscovered on the Madonie Mts. in 1937. Sicilian fir is recognized as one of the most endangered coniferous species in the world. It is classified as critically endangered by IUCN, and also included in the list of 50 most endangered plant species in the Mediterranean region. Currently, the limited population size, a small proportion of reproductive individuals, habitat loss, ongoing and projected climate change, and hybridization with other species pose serious threats to survival of this species. Therefore, it is extremely important to maintain actions focusing on in situ and ex situ conservation in order to preserve and protect the existing resources of Sicilian fir, which represents the natural heritage unique to the Mediterranean.

Opis:
Dionysia involucrata Zaprjag. (Primulaceae) is known as critically endangered endemic species of Hissar Mountains in Tajikistan. It is reported from few localities mainly in Varzob River valley and its tributaries. The species inhabits steep or overhanging faces of granite rocks in narrow river gorges. During the research all known populations of D. involucrata were examined in respect of the habitat conditions and species composition of vegetation plots. We analyzed the population extent of the species in its range in Tajikistan and the main threats in order to assess its conservation status. The detrended correspondence analysis was performed on a matrix of 65 relevés and 49 species (vascular plants and mosses), to classify the phytocoenosis with domination of D. involucrata according to their floristic composition in relation to other petrophytic vegetation units. Using our field data regarding present extent of occurrence and area of occupancy we conclude that the threat category of D. involucrata should be reassessed from critically endangered to endangered. The species shows decline tendency in extent of occurrence, area of occupancy as well as in number of locations. The vegetation plots with domination of D. involucrata have relatively high level of separateness due to different species composition. We define the new association – Dionysietum involucratae – representing chasmophytic vegetation of submontane and montane zone in Middle Asia (ca. 1000–1600 m a.s.l.). The plots of Dionysietum involucratae were found mainly on granite rocks, on very steep or overhanging faces, on southwestern or southern exposition. The association is rather poor in species with inconsiderable contribution of mosses. Despite the diagnostic species, Campanula incanescens, Carex koshewnikowii and Scutellaria hissarica were the most abundant and frequent taxa within the researched patches of vegetation.

The results showed that leaves are abundant of cis-3-hexenyl benzoate (10.75%), benzyl benzoate (8.16%) and caryophyllene oxide (8.12%). The main compounds of stems were benzyl benzoate (21.92%), E-nuciferol (11.58%) and dibutyl phthalate (7.08%), while major components of flowers were benzyl benzoate (9.99%), caryophyllene oxide (8.14%) and E-nuciferol (8.13%). The antioxidant activities of methanol extract were evaluated by DPPH and β-carotene/linoleic acid assays. The results showed that in both methods, leaves had stronger antioxidant activity than other organs.

Opis:
Allium jesdianum Boiss. & Buhse (Yazdi onion) belonging the family Alliaceae, is an endemic species of Iran that grows wild in the Zagros Mountains range, southwestern Iran. The indigenous people of Iran use the leaves and bulbs of A. jesdianum for the treatment of colds and kidney problems. The bulbs and leaves of various populations of the plant were collected from the alpine regions in Chaharmahal va Bakhtiari province, southwestern Iran. The total phenolic content of ethanol extract was determined by FolinCiocalteu method, the antioxidant activity was evaluated measuring 1,1-diphenyl-2-picrylhydrazyl (DPPH), and the antibacterial activity of the extracts against four bacteria was determined by serial dilution assay. Results indicated that the total phenolic content in ethanol extracts from leaves and bulbs of A. jesdianum ranged between 27.83 to 98.23 mg GAE/g extract. A comparison of all plant extracts in the DPPH assay indicated that ethanol extracts from the populations of A. jesdianum leaves were the most effective free radical scavenging agents. The extracts indicated moderate-to-good inhibitory activities against four bacteria, especially against B. cereus. This finding suggests that the bulbs and leaves of A. jesdianum may be considered a natural source of antioxidants and antimicrobial agents.

In this paper, the rediscovery of endemic and long missing species, Scilla mesopotamica Speta which had been only known from the type gathering, is given. The species has not been collected again after Sintenis in 1888, whose specimens served Speta for description of the new taxon. In 2004, the authors found it in a steppic rocky area, near Halfeti in Şanliurfa province, South East Anatolia, Turkey. After analyzing Sintenis' original collection notes, they concluded that this area is identical with the type locality. S. mesopotamica has an extremely limited distribution and is represented by less than 200 specimens in the single known population that covers less than 50 m2. Taxonomy of the species, detailed description with illustrations, geographical distribution, habitat, ecology and status of IUCN extinction risk and some comments on conservation of the plant are also presented.

Opis:
Cochlearia polonica Fröhl. (Brassicaceae) is one of the rarest species in the Polish and European flora and a taxon endemic to a very small area in southern Poland. Due to industrial activities and subsequent transformation of habitats it was extinct in all natural localities around 1994. The persistence of the species was ensured thanks to the active protection efforts including a series of transplantations based on the material from the last and decreasing natural population. The history of conservation efforts of C. polonica provides a model example of successful active protection in the European flora. Here, we provide a complete review comprising the following aims: (i) outline of the discovery and taxonomic conceptions on C. polonica, (ii) review of conservation efforts aimed at preserving its populations, (iii) description of the existing population resources, and (iv) analysis of the genetic structure of all existing populations based on previously published data and new, supplementary results.

Opis:
Genetic diversity of Galium cracoviense, a narrow endemic species, limited to the small area in southern Poland and concentrated on Jurassic limestone outcrops near Częstochowa, was examined using the AFLP marker. Twenty nine individuals from three spatially isolated populations were used for the study. AFLP analysis yielded 157 bands, of which 110 (70%) were polymorphic. The AMOVA analysis revealed a substantially higher variation within populations (89.35%) than among them (10.65%). Values of parameters describing population genetic diversity, such as Shannon index and gene diversity index estimated for each population, were highly similar. The results indicate a high level of genetic polymorphism as well as a high genetic similarity of the isolated populations of G. cracoviense and thus an unconstrained gene flow between them. Based on the results we conclude that additional demographic and genetic studies, are necessary to monitor potential decrease of populations size resulting mainly from the mechanical destruction of plants and their habitats caused by intense tourism. Due to the small general range of occurrence, conservation should include the highest possible number of populations of G. cracoviense.

Opis:
Galium sect. Leptogalium Lange in NE Europe is represented by few, local endemic species which occur in the area covered by the continental ice sheet in the Pleistocene period. They are: G. cracoviense Ehrend. in S Poland, G. oelandicum (Sterner & Hyl.) Ehrend. in SE Sweden and G. sudeticum Tausch in SW Poland and N Czech Republic. 55 individuals from five populations of these species were analysed using AFLP markers. A total of 193 AFLP bands were detected using three combinations of primers; out of them 159 proved polymorphic (82.4%). The lowest values of Shannon's index and Nei's gene diversity were noted for G. oelandicum and the highest ones for G. sudeticum. The results indicate a relatively high level of genetic variability in each of endemic species in spite of that the studied species occupy very small areas and are represented by a low number of populations. We conclude that additional, demographic and genetic studies are necessary to monitor potential decrease of populations' size resulting mainly from the mechanical destruction of plants and their habitats caused by intense tourism or other human activities (as agriculture, e.g. grazing).
