Given the long and continuous history of human settlements on the territory of Novi Sad, the human impact on the Danube?s coast configuration has been significant. Based on the field research and literature data regarding the Danube?s shoreline, from Cerevic to Cortanovci, a total number of 440 taxa classified into 224 genera and 68 families were registered. According to the number of species, the most abundant families were Asteraceae (51), Poaceae (49), Fabaceae (32) and Brassicaceae (28), while the most abundant genera were Carex (15), Rumex (10) and Euphorbia (8). Chorological analysis showed that 42% of the registered taxa belong to Eurasian floral element, 14% to Central European and 12% to Pontic-Southsiberian floral element, with special attention to alien plants with invasive character that included 24 taxa. The analysis of the life forms showed domination of hemicryptophytes (40%), followed by therophytes (27%) and phanerophytes (11%).

River ports represent a special type of urbanized area. They are considered to be an important driver of biological invasion and biotic homogenization on a global scale, but it remains unclear how and to what degree they serve as a pool of alien species. Data for 54 river ports (16 German, 20 Czech, 7 Hungarian, 3 Slovak, and 8 Austrian ports) on two important Central European waterways (the Elbe-Vltava and Danube waterways) were collected over 40 years. In total, 1056 plant species were found. Of these, 433 were alien, representing 41% of the total number of species found in all the studied Elbe, Vltava, and Danube ports. During comparison of floristic data from literary sources significant differences in the percentage of alien species in ports (50%) and cities (38%) were found. The number of alien species was closely related to port size, but the proportion of alien species expressed as a percentage of the total number of species did not depend significantly on port area. The proportion of alien species in both studied waterways decreased with distance from the sea and was highest in the Hungarian ports and lowest in the Czech Republic, Austria and Bavaria. Lower levels of shipping towards inland regions due to decreased river flow are likely the reason for this trend. The dissimilarity in the species composition of alien and native flora between individual river ports increased with increasing inter-port distance. Neophytes presented a stronger distance decay pattern than did either native species or archaeophytes of the Danube inland ports, potentially due to the different cargoes of individual ports, which may affect the introduction of different neophytes from different geographic areas. The results show that river ports in Central Europe should be regarded as a type of industrial area and deserve full attention with regard to the distribution and spread of alien plants.

The purpose of this study is to present the distribution and characteristics of xerothermic flora located within Lublin (51<sup>o</sup>08’-51<sup>o</sup>18’N and 22<sup>o</sup>27’-22<sup>o</sup>41E). The data on this flora have been derived from the literature and herbarium collections as well as they were collected during field research conducted in 2002-2009. Family affiliation, life forms, geographical-historical groups, the degree of synanthropization of species and habitat, categories of threat are discussed in this paper. 107 xerothermic species belonging to 26 families and 70 genera were reported from the area of Lublin. The number constitutes 10% of the city’s flora. The most numerous are plants from the classes <i>Festuco-Brometea</i> (70 species), <i>Trifolio-Geranietea</i> sanguinei (21) and <i>Rhamno-Prunetea</i> (16). All extinct species (8) belong to the class <i>Festuco-Brometea</i>. The analysis of the spectrum of life forms indicates that the biggest share in the flora of Lublin was observed in the group of hemicryptophytes (57 species) and phanerophytes (14). The native species (103) dominate over the group of alien ones (4 species). The group of xerothermic plants comprises 21 legally protected and endangered species. Xerothermic plants exhibit a mosaic distribution in the area of Lublin. The frequency (measured as the presence of a species in a study unit, one ATPOL square) ranged from 1 to 44 species. Two main features of the analyzed area seemed to be responsible for species distribution: the value of the Real Hemeroby Index (RIH) and the history of the flora.

This paper analyses ecological features of bryophyte species from the territory of the Pohulyanka Forest Park in the city of Lviv, Ukraine. A total of 141 species of bryoflora were analyzed (70 recorded for the first time). In the spectrum of life forms (LF), species with the following LF prevailed in the study area: turf (61 species, 43.3%), mat (48 species, 34%). Turf, the most common life form, was detected on all types of substrates, but was most frequently found on the soil (33 species, 23.4%) and stony substrates (13 species, 9.2%). Analysis of herbarium specimens (herbariums of Ivan Franko National University of Lviv, National Museum of Natural History of the National Academy of Sciences of Ukraine, and the Institute of Ecology of the Carpathians of the National Academy of Sciences of Ukraine) and the results obtained with respect to the composition of the bryoflora suggest that since the mid-19th century, due to anthropogenic transformation of the study area, most species with LF weft (10 out of 15 species, or 66.7%) have disappeared, while the number of species with LF rough mat on the soil has increased. The apophytic fraction of bryoflora in the study area consists of 121 species (85.8%) belonging to 28 families and 66 genera, including four species in the division Marchantiophyta. In the composition of bryophyte flora, 67 species of eventapophytes were identified (47.5% of the total number of species). Dominant families are Brachytheciaceae, Mniaceae, Pottiaceae, Plagiotheciaceae, Orthotrichaceae, Polytrichaceae. Hemiapophytes comprised 24.1% (i.e. 34 species) of the total number of species. The largest number of hemiapophytes was found in the families Pottiaceae, Bryaceae, Amblystegiaceae and Orthotrichaceae. Among the spontaneophytes (20 species, 14.2%), the families Hypnaceae, Mniaceae and Polytrichaceae prevailed. Indigenophytes amounted to 20 species (14.2%). With regard to the relationship of bryophytes to light, the following groups were identified in the study area: ultraheliophytes, heliophytes, subheliophytes, hemisciophytes and sciophytes. The highest number of species was represented by subheliophytes and hemiscyophytes. Certain patterns were found in the ratio of sun-demanding species in groups of apophytes. Among the hydromorphs, the following groups were identified: ultraxerophytes (found only among hemiapophytes); xerophytes (prevailing in the group of hemiapophytes, but also found among eventapophytes); xeromesophytes, mesophytes, hygromesophytes and hygrophytes (represented in all anthropotolerant groups); hydrophytes (event- and spontan/indigenophytes).

Nine hundred and forty seven species of vascular plants under 661 genera and 172 families were recorded from Morang district and adjoining areas of Nepal. The genus-species ratio of the vascular plants in general and angiosperms in particular was 1:1.43 and 1:1.44, respectively; and 498 genera of vascular plants were represented by a single species only. On the basis of number of species, Polypodiaceae (11) was the largest family of pteridophytes, and Pinaceae (3) of gymnosperms. Among the angiosperms ten largest families were: Leguminosae (91)>Poaceae (80)> Asteraceae (57)>Euphorbiaceae (31)> Cyperaceae (28)> Rubiaceae(26) > Lamiaceae and Solanaceae (22 each) > Acanthaceae (21)> Orchidaceae (20) > Convolvulaceae (16). The biological spectrum of the study area was phanerotherophytic type.

Kedudukan dan fungsi bahasa sebagai alat komunikasi manusia mencakup seluruh bidang kehidupan termasuk ilmu pengetahuan antara lain terkait sejarah peradaban manusia; bagaimana manusia mempertahankan hidupnya, bagaimana manusia memperlakukan alam, bagaimana alam menyediakan segala kebutuhan manusia. Apa yang dilakukan manusia saat ini, saat lampau, dan apa yang dilakukan manusia jauh di masa prasejarah, bagaimana kondisi alam di masa-masa tersebut, apa perubahan dan perkembangannya, dapat didokumentasikan melalui bahasa, divisualisasikan kembali, lalu dipajang sebagai salah satu upaya konversai dan preservasi dalam satu institusi yang disebut museum. Penelitian ini membahas kedudukan dan fungsi bahasa dalam permuseuman. Bagaimana kedudukan dan fungsi bahasa dalam permuseuman baik dalam informasi yang disampaikan oleh pemandu wisata museumnya maupun yang terpajang menyertai benda-benda dan gambar-gambar merupakan tujuan dari penelitian ini. Metode penelitian yang digunakan adalah gabungan antara metode lapangan dan metode literatur. Hasil penelitian menunjukkan bahwa secara umum kedudukan bahasa Indonesia berada pada urutan pertama setelah Bahasa Inggris dan keberadaan kedua bahasa dalam permuseuman ini melibatkan dua fungsi utama bahasa, yakni fungsi komunikatif dan fungsi informatif.The existence and function of language  as a medium of communication covers all fields of human life including knowledge, one of them is the history of human civilization; how humans survived, how human utilized nature for their lives, and how nature provides all the necessities for humans. What humans have been doing now, what they have done in the past and far before that in the pre-history time, how the conditions of the nature at those times were and what changes as well as progresses occurred are documented using language, then re-visualized,  displayed as one of conservation and preservation acts in an institution called museum. This research discusess the existence and function of language in museums. How important the existence of a language in museums and what language functions used in museums both in informations given by the museum guides and on the displays accompanying objects and pictures are the aims of this research. The methods used are the combination between field research and library research. The results show that generally the existence of Indonesian language plays more important role than English and both languages have two main functions; communicative function and informative function.

Two computer data bases were formed: reference base «Prodromus» including the nomenclature forest syntaxa and experienced geobotanic releves «Forests of European Russia». Ecological, coenotic and floristic analysis of broadleaved-coniferous forests mostly corresponding to association Rhodobryo rosei – Piceetum abietis Korotkov 1986 was conducted with these bases. Releves (305) from South taiga and broadleaved-coniferous subzone were used. The analysis revealed complex syntaxonomy, bo­real-nemoral character and wide distribution ass. Rhodobryo-Piceetum from central European Russia. Ecolo­gical comparison of this association with some no­men­clature types of broadleaved-coniferous communities in East Europe was carried out. Preliminary prodromus for Euro­pean Russian mixed forests is suggested. Role of ecologi­cal, succession and regional factors was shown for dif­ferentiation of syntaxa.

AbstractStudies on plant invasions depend on local and regional checklists of the alien flora. However, global overview studies have shown that some regions, including many African countries, remain understudied in this regard. To contribute to filling this gap, here we present the first checklist of alien plants of Sudan and South Sudan (the Sudans). We analysed the taxonomic and geographical composition of the species on this list. Our result show that of the 113 alien species in Sudans (99 in Sudan and 59 in South Sudan), 92 (81.4%) are naturalized and 21 (18.6%) are just casual aliens. The number of naturalized species represent 2.2% of the total flora of the Sudans (4096). The alien species belong to 44 families and 85 genera, and many of them are native to Southern America and Northern America (85.8%). Annual and perennial herbs are the prevailing life forms in the alien flora of the Sudans (68.1%), and, among the casual species, perennial herbs are underrepresented whereas woody tree species are over-represented. Alien plants of the Sudans are mostly used for medicinal and environmental purposes globally. The naturalized plants predominantly occur in man-made disturbed habitats, such as agricultural and ruderal habitats. This first overview of the alien flora of the Sudans should stimulate further research and recording of the alien flora to better understand the drivers and consequences of alien plants in the Sudans.
