Vitis vinifera ‘Guifeimeigui’ is a diploid table grape, a Eurasian species. This research first reported the complete chloroplast (cp) genome of Vitis vinifera ‘Guifeimeigui’. The size of the complete cp genome is 160,928 bp and its GC content is 37.38%, including a pair of inverted repeats (26,353 bp each) separated by large (89,150 bp) and small (19,072 bp) single-copy regions. It encodes 85 genes, including 40 protein coding genes, 37 transfer RNA genes (tRNA), and 8 ribosomal RNA genes (rRNA). The Maximum Likelihood (ML) phylogenetic tree demonstrated that Vitis vinifera ‘Guifeimeigui’ is close to Vitis vinifera.

Abstract S. cinerea (grey sallow) is included in the section Capreae of subgenus Caprisalix (Rechinger, 1964). It is a broadleaved willow, typically a large shrub generally much branched from the base with numerous intercrossing branches. Bark is dark grey, becoming fissured with age. The species forms a broad, rounded crown. Twigs are densely pubescent, remaining so at least until the end of the first year; wood of peeled twigs with long, scattered striae. Leaves very variable, usually ovate or oblanceolate, 2-9 cm long, 1-3 cm wide, dull grey-green and pubescent above or dark green and slightly lustrous. Catkins appearing in advance of the leaves in March and April. Male flowers with 2 free stamens. Capsule up to 10 mm (Meikle, 1984; Newsholme, 1992). S. cinerea is a Eurasian species, common throughout Europe, from the Mediterranean to Scandinavia (including Spain and Portugal, Sicily, Sardinia, Corsica, the Aegean Islands and Turkey). Its range extends eastward to Asia, from the Crimea to the Caucasus, from northern Iran to Siberia, and north of the Caspian and Aral seas to the Chinese border (Jalas and Suominen, 1976; Skvortsov, 1999).It is a useful species in erosion control projects, and to protect marshlands and riverbanks. Because of its early flowering, it is also important for honeybees (Schiechtl, 1996). Hybrids with S. viminalis (S. × calodendron) are grown in the UK, Germany and Denmark to produce biomass as a energy source (McElroy et al., 1983).

The relict tree species Zelkova abelicea and Z. sicula (Ulmaceae) occur in Crete and Sicily, respectively. Zelkova abelicea grows in approximately 40 localities in the mountains of Crete, while Z. sicula has been found in only two stands in Sicily. We compared 25 morphological characters of the leaves of both species and used statistical methods (Tukey’stest, discrimination analysis, principal component analysis, agglomeration) to reveal the differences between these two species, their relation to Z. carpinifolia (the third Zelkova south-west Eurasian species), and between the leaves from different shoot types. Our study represents the first comparative biometric analysis of the three Zelkova species localized in the western edge of the current geographic range of the genus. We found that the species differed from each other both, in terms of leaf form characters and level of leaf variation. Zelkova carpinifolia was clearly different from Z. abelicea, while the two populations of Z. sicula, SIB and SIA, were more similar to Z. carpinifolia and Z. abelicea, respectively. The latter finding supports the results of recent molecular studies suggestingt he hybrid origin of Z. sicula. Zelkova abelicea, Z. sicula and Z. carpinifolia differ each other in the leaf characteristics and level of phenotypic variation.

Wetlands are among the most fragile habitats on Earth and have often undergone major environmental changes. As a study case in this context, the present work aims at increasing the floristic knowledge of a reclaimed land now turned into an agricultural lowland with scarce patches of natural habitats. The study area is named Piana di Rosia, and it is located in southern Tuscany (Italy). The compiled checklist consists of 451 specific and subspecific taxa of vascular plants. The life-form spectrum shows a predominance of hemicryptophytes, followed by therophytes. The chorological spectrum highlights a co-dominance of Euri-Mediterranean and Eurasian species along with many widely distributed species. The checklist includes seven species of conservation concern, three Italian endemics (Crocus etruscus Parl., Polygala vulgaris L. subsp. valdarnensis (Fiori) Arrigoni, and Scabiosa uniseta Savi), 41 alien species, 21 segetal species, and 11 aquatic macrophytes of which five helophytes and six hydrophytes. This study suggests that irreversible land-use changes in wetlands can lead towards a simplification of the flora. However, despite the deep transformations that the former wetland has undergone, the presence of some aquatic and protected taxa is interesting. From a conservation point of view, the natural value of this agricultural area could be enhanced and its current management partly reconsidered, thus preserving the remnants of naturalness present.

The systematic knowledge on the genus Hedysarum L. (Fabaceae: Hedysareae) is still incomplete. The species from the section Hedysarum are valuable forage and medicinal resources. For eight Hedysarum species, we constructed the integrated schematic map of their distribution within Eurasia based on currently available scattered data. For the first time, we performed cytogenomic characterization of twenty accessions covering eight species for evaluating genomic diversity and relationships within the section Hedysarum. Based on the intra- and interspecific variability of chromosomes bearing 45S and 5S rDNA clusters, four main karyotype groups were detected in the studied accessions: (1) H.arcticum, H. austrosibiricum, H. flavescens, H. hedysaroides, and H. theinum (one chromosome pair with 45S rDNA and one pair bearing 5S rDNA); (2) H. alpinum and one accession of H. hedysaroides (one chromosome pair with 45S rDNA and two pairs bearing 5S rDNA); (3) H. caucasicum (one chromosome pair with 45S rDNA and one chromosome pair bearing 5S rDNA and 45S rDNA); (4) H. neglectum (two pairs with 45S rDNA and one pair bearing 5S rDNA). The species-specific chromosomal markers detected in karyotypes of H. alpinum, H. caucasicum, and H. neglectum can be useful in taxonomic studies of this section.

Ranunculus pedatus is a Eurasian species with a northern distribution edge in southern Slovakia. In the nineties of the 20th century, it was assumed that the species probably occurs only near Štúrovo. Occurrence in the Hron and Ipeľ basins and several localities in the Podunajská nížina lowland between Komárno and Štúrovo was considered historical. Our research was conducted in the field and herbarium collections of 15 herbaria in Austria, the Czech Republic, Hungary, and Slovakia. Except for the well-known occurrence on salt habitats north of Štúrovo, we confirmed the recent occurrence of R. pedatus in Štúrovo town, around Chľaba village and in Ipeľ Basin (Pastovce, Tupá). The new, easternmost Slovak locality was found near the village of Koláre. Recently, 30% of all known sites were confirmed, so we propose reclassifying the species in Slovak Red List from the category critically endangered (CR) to the category endangered (EN). It occurs in salty meadows of the alliance Festucion pseudovinae (class Festuco-Puccinellietea) and in mesic meadows of alliance Arrhenatherion elatioris and Deschampsion cespitosae (class Molinio-Arrhenatheretea).

The goal of the paper is to identify the features of the breeding ecology of the Motacilla alba baicalensis in the Baikal region and Transbaikalia. The nesting ecology study deliverable of the Motacilla alba baicalensis in the Baikal region and Transbaikalia showed that this subspecies, unlike other forms, is more synanthropic, more than 95% of populations live in localities and other anthropogenic habitats, and only 23% of populations inhabit natural biotopes. At the same time, the Motacilla alba baicalensis in the region prefers small rural settlements and livestock camps in open landscapes near reservoirs. When the Motacilla alba baicalensis builds nests, like other subspecies, it is quite plastic and easily finds shelter in various anthropogenic and natural biotopes. The higher nesting efficiency of this subspecies indicates its wide opportunities to develop anthropogenic landscapes. Due to the short favorable nesting period, most pairs manage to hatch chicks once, but only a small number of pairs manage to raise chicks twice a season. A comparison of the nesting ecology of the Motacilla alba baicalensis with other forms of the Northern Eurasian species did not reveal any fundamental differences. The differences relate to the phenology of different stages of the breeding season, as well as the timing of arrival and departure of birds.

The state of Iris sibirica L. in the national botanical reserve "The Valley of the Irises" is characterized. In particular, it was found that I. sibirica should be classified in the group of Euro-West Siberian, and not as a Euro-Siberian or even Eurasian species. Phenological rhythms and peculiarities of fruiting have been studied. It is established that the duration of the vegetation period of I. sibirica lasts 187–246 days. The most important stages of the reproductive cycle of I. sibirica (structure of inflorescences, flowers, fruits and seeds, phenology, seed productivity) have been studied. We first discovered that on the inner surface of the flower tube there is a multilayer secretory tissue – perigonal nectar. The fruiting of I. sibirica, which lasts quite a long time: 2–3 months (60–80 days) from June to August, was studied. In this population two ways opening of the capsule were observed. Apis mellifera (Linnaeus, 1758) (honey bee) and Bombus bombus (Latreille, 1802) (bumblebee) are pollinators of I. sibirica in the reserve. The coefficient of seed productivity of I. sibirica was high and quite stable, but despite the high potential and actual seed productivity in the population there is a weak seed recovery, which is associated with high turfing and invasions of members of the phytophagous genus Ceutorhynchus. Their activity dramatically reduces the maturation and dissemination of full-fledged mature seeds due to damage to flowers, capsules and seeds in them. However, the population of I. sibirica in the "The Valley of the Irises" is mature, normal, with a slight predominance of young individuals, which provides it with positive dynamics.

Abstract The Miocene-Pliocene (Turolian-Ruscinian) transition represents a fundamental interval in the evolution of Euro-Mediterranean paleocommunities. In fact, the paleoenvironmental changes connected with the end of the Messinian salinity crisis are reflected by a major renewal in mammal faunal assemblages. An important bioevent among terrestrial large mammals is the dispersal of the genus Sus, which replaced all other suid species during the Pliocene. Despite its possible paleoecological and biochronological relevance, correlations based on this bioevent are undermined by the supposed persistence of the late surviving late Miocene Propotamochoerus provincialis. However, a recent revision of the type material of this species revealed an admixture with remains of Sus strozzii, an early Pleistocene (Middle Villafranchian to Epivillafranchian) suid, questioning both the diagnosis and chronological range of P. provincialis. Here we review the late Miocene Suidae sample recovered from the Casino Basin (Tuscany, central Italy), whose taxonomic attribution has been controversial over the nearly 150 years since its discovery. Following a comparison with other Miocene, Pliocene, and Pleistocene Eurasian species, the Casino Suidae are assigned to P. provincialis and the species diagnosis is emended. Moreover, it is recognized that all the late Miocene (Turolian) European Propotamochoerus material belongs to P. provincialis and that there is no compelling evidence of the occurrence of this species beyond the Turolian-Ruscinian transition (MN13-MN14).
