“…Many of these gardens have been abandoned or they have been built-up. In the remaining gardens, gardeners now grow fewer crops [26]. Among these crops are several archaeophytes (such as Armoracia rusticana, Raphanus raphanistrum, Sinapis arvensis) that are present in a smaller percentage of recent relevés or in none, although they were present in ruderal communities in the past (Tab.…”

“…The altitude ranges from 126 to 514 m a.s.l. The area of Bratislava lies within three orographic units: flatland Podunajská rovina, lowland Borská nížina, and Malé Karpaty Mts [26]. The climatic conditions of the area range from moderate to warm continental character and the city is one of the warmest and driest regions of Slovakia.…”

“…The average duration of sunshine is one of the longest in Slovakia (50% = 2100 h/year; in the vegetation period it is 60% = 1600 h). In ruderal habitats, soil conditions are influenced by human actions and natural soils are covered by anthropogenic ones [26].…”

“…The natural potential vegetation of Bratislava consisted mainly of forests: Carpathian Quercus-Carpinus forests and Fraxinus-Ulmus-Quercus floodplain forests in the Borská nížina, Carpathian Quercus-Carpinus forests, acidophilous Fagus forests, Pontic-Pannonian Quercus forests in the Malé Karpaty Mts, and Fraxinus-UlmusQuercus floodplain forests and Salix-Populus floodplain forests in the Podunajská rovina [26].…”

The study is focused on evaluating changes in the presence of alien species in ruderal vegetation. Two datasets comprising phytosociological relevés of ruderal communities during two time periods within the Bratislava City (in southwestern Slovakia) were analyzed. The old dataset consisted of 387 relevés recorded in the years [1975][1976][1977][1978][1979][1980][1981][1982], and the more recent dataset consisted of 308 relevés from the years 2011-2014. The relevés from both time periods were assigned to phytosociological classes via the same procedure -numerical classification (hierarchical clustering) using HIERCLUS software. The average values of the percentage number and percentage cover of the archaeophytes and neophytes as groups in the earlier and more recent relevés of each class were compared by the main effects ANOVA analysis in the STATISTICA 7.0 software. The proportion of each taxon of archaeophytes and neophytes in both datasets was also calculated. The invasive status, origin, and life forms of alien species in both datasets were compared. In total, both datasets comprised 120 archaeophytes and 71 neophytes. The old dataset contained more archeaophytes than the more recent dataset. On the contrary, the more recent dataset contained more neophytes than the old dataset. In the years 2011-2014, more invasive neophytes were recorded than in the past. The results revealed a statistically significant decrease in the average percentage number of archaeophytes in the classes Stellarietea mediae, Artemisietea vulgaris, and Galio-Urticetea, and a decrease in the average percentage cover of archaeophytes in the class Artemisietea vulgaris, compared to the past. On the contrary, a statistically significant increase in the average percentage number and cover of neophytes in the classes Artemisietea vulgaris and Galio-Urticetea was recorded. Some rare species of archaeophytes were only recorded 30 years ago (e.g., Kickxia elatine, Silene gallica). Furthermore, several species of neophytes (including some invasive taxa, e.g., Fallopia japonica, Helianthus tuberosus, Juncus tenuis) occur only currently in the ruderal vegetation of Bratislava.
