Synanthropic Flora

The results of a long-term studu of the flora of technologenichabitats of the taiga zone of the Komi Republic are summarized. An annotated list of vascular plants is presented, including 406 species from 222 genera and 52 families. For each of them, it is indicated that they belong to a life from, an element of the flora and type of area, an ecologicsl group, zonal and ecotopic affinity. Data on the taxonomic composition of vascular plants, the biomorphrological, geographical, and ecological structures of synanthropic flora, the diversity of synanthropic plant communities, and the stages of vegetation restoration in disturbed areas are presented.

Mashkova IV, Krupnova TG, Kostryukova AM, Vlasov NE. 2018. Short Communication: Biodiversity of weeds in Ilmen State Reserve, Russia. Biodiversitas 19: 106-111. Weeds are a synanthropic flora. Human exposure to the natural landscape leads to the spread of synanthropic plant species, so weeds begin to occupy a significant place in the structure of ecosystem biodiversity. The aim of this study was to investigate the weeds biodiversity structure and to assess the extent of invasion of weeds into the territory of the Ilmen State Reserve in South Urals, Russia. This paper presents the results of study of weeds during the vegetation period in 2013–2017. Fifty one species of weeds distributed in four genera and six families were found on the territory of the Southern Forestry of the Ilmen State Reserve. Besides, the differences between species diversity of weeds on three types of roads (gravel, earth and foot) and on two types of forests (birch and pine) were also discovered in this study . The greatest degree of invasion was discovered for foot roads. It was noted that pine forest is the most resistant the invasion of weeds.

Synanthropic Flora

The impoverishment of synanthropic vegetation has been observed in Polish cities for at least half a century. It relates to both the decrease in the area of its occurrence and reduction in species diversity. This is associated with changes in land development, a faster construction process, and an increasingly smaller area of wasteland as well as with the fact that agricultural land and farm buildings are found in cities less and less frequently. Municipal management has been modernised and rubbish, soil or rubble dumps are encountered less often. Besides, the aesthetics adopted by modern man does not allow for the existence of spontaneous vegetation, since in an ordered world such great freedom and liberty are not accepted. Nevertheless, synanthropic flora is one of elements of greenery co-creating a unique urban ecosystem. It increases species richness, improves the climate, and contributes to a reduction in pollution and noise. The present paper highlights difficulties related to the preservation of this flora in cities, and a concept is presented how to introduce it into urban green spaces. Different forms of green spaces are presented in the case of which it is possible to use synanthropic plants, e.g.: ecological lawns and flower meadows, extensive roof gardens, and ecological parks.

Synanthropic Flora

<p>Floristic studies were carried out in eight botanical gardens in Poland in the years 1992-1999. It was demonstrated that the spontaneous synanthropic flora of the gardens consisted of 1092 taxa in the rank of a genus or lower, among which alien species constituted 55% of the flora studied. Ergasiophygophytes, of which the introduction is closely associated with the activities of the botanical gardens, dominated in the latter group of species.</p><p>It appeared that the flora of the studied botanical gardens was rather similar. However, the structure of the flora of different spatial units (six types of microhabitats) distinguished in the particular gardens varied, which was associated with the various management practices. The flora of microhabitats identified in the gardens differed with respect to the number of taxa and spectra of geographical-historical groups of species and life forms. Ruderal sites, arable lands and roadsides supported the highest number of taxa (the flora of the above spatial units was represented by 646, 645 and 597 taxa, respectively). Moreover, they were characterized by a high proportion of annual plants in the flora (43, 38 and 34%, respectively) and by a relatively small representation of apophytes (39% in all the three types of microhabitats). The flora of wet areas and parks was, however, poor in species (154 and 403 species, respectively), but relatively rich in apophytes (72 and 55% of the flora, respectively) and with a low contribution of therophytes (19 and 20%, respectively).</p><p>The present data were compared with the findings of other authors who investigated the synanthropic flora of cities in which the botanical gardens were located. The comparative analysis of the flora of Poznań and Łódź showed a great richness of species (in relation to size of the area studied) and a high incidence of aliens (especially those, which had not become established permanently) in the botanical gardens. However comparative studies of the flora of Warsaw and that of the two botanical gardens established in the city revealed that the proportion of alien species was lower in case of these gardens.</p><p>In Warsaw the flora of areas, which had been managed in the same way as those of the botanical gardens, was also investigated. It was found that the botanical gardens in Warsaw were more similar to cemeteries with respect to the structure of flora than they were to the allotments. The present study showed that the high variability of flora within the particular gardens is attributed to the different ways the area is utilized.</p>

Synanthropic Flora

The aim of the work was to estimate the specific role that Central European botanic gardens play in the dispersal of alien plants, which results from the wide variety of plants cultivated in the gardens and regular international exchange of plant material between these institutions. We compared the results of recent field studies (in eight Polish botanic gardens) and a review of older literature data and herbarium collections (from Central European botanic gardens). We found that in Poland the proportion of botanic garden escapes was lower (3%) than would be expected from the "tens rule". Botanic gardens have played a considerable role in the development of the synanthropic flora of Central Europe in the last 200 years. We determined a group of species introduced through a network of botanic gardens and propose 5 theoretical patterns to describe the mode and pathways of the early stages of introduction of these species.
