Beniak M., Pauková Ž., Fehér A.: Altitudinal occurrence of non-native plant species (neophytes) and their habitat affinity to anthropogenic biotopes in conditions of South-Western Slovakia.Many ecological studies showed that species density (the number of species per unit area) in nonnative organism groups of the mountain areas decreases with increasing altitude. The aim of the paper is to determine the variability in the incidence of non-native plant species (neophytes) associated with the change in altitude and links of the invading taxons to reference habitat types, as well as their links to three ecologically very similar, however in natural conditions, different areas. In general, the most invaded habitats are those which are highly influenced by human activities. Firstly, data collection was conducted through field mapping of build-up areas in South-western Slovakia. Subsequently, with the assistance of ordination methods, we evaluated the level of association of invasive neophytes according to the set objectives. We found that altitude was an important factor determining variability of invasive neophytes' occurrence. Total amount of habitats with invasive neophytes' occurrence showed a linear increase along the altitudinal gradient. Many invasive neophytes adapted to abandoned habitats of upland territory were also able to grow along roads, and vice versa, abandoned and unused habitats of lowland areas created conditions for many typical invasive neophytes occurring along roads and habitats of gardens and yards. Railways of lowland areas provided habitats and means of spread of invasive woody neophytes. Gardens and yards were important sources of alien neophytes in all observed territories. Invasive neophyte Aster novi-belgii can be described as a very variable species tolerant to a wide range of factors limiting the spread of species along the elevation gradient.

“…Vascular plant diversity is determined, in part, by floods and ground water that maintain heterogeneity in habitats and variation in microsites on alluvial surfaces (Pollock et al 1998;Tabacchi et al 1998;Stanford et al 2005;Jansson et al 2007; Mouw et al 2009). Non-native plants also occur in the diverse plant assemblages along rivers (Planty-Tabacchi et al 1996;Hood and Naiman 2000;Richardson et al 2007), and riparian areas serve as corridors for spread of exotics (Stohlgren et al 1998;Tickner et al 2001). However, soil-based mechanisms underlying success of non-native species remain poorly understood in riparian zones, as well as in other ecosystems (Beauchamp et al 2005;Wolfe and Klironomos 2005).…”

Arbuscular mycorrhizal fungi enhance spotted knapweed growth across a riparian chronosequence

et al. 2009

Arbuscular mycorrhizal fungi (AMF) mediate nutrient uptake that accelerates plant growth and reproduction. Thus, AMF may promote plant invasions often observed along rivers. We assessed the importance of AMF in improving growth of the invasive species, spotted knapweed (Centaurea stoebe), during succession of riparian vegetation along a flood plain in Montana, USA. We grew spotted knapweed with and without AMF in soils collected from riparian sites ranging from 1 to 72 years old and measured the plant's growth response to AMF. We observed variability in relative effects of AMF, with greatest growth benefits in recently deposited alluvial sediments. We then separated effects of soil and inoculum source by growing spotted knapweed with soils and inocula collected from young or old sites and found that growth responses were greatest in young soils regardless of inoculum source. Our results demonstrate that AMF directly benefit growth of spotted knapweed, especially in soils that typify early successional sites on this alluvial flood plain.

“…This observation confirms both high efficiency of riverine valleys as invasion pathways and high invasibility of river valleys. This invasibility results from availability of necessary resources (water, light and nutrients), as well as from frequent disturbances which create new, empty habitats, without the limiting influence of competitors (Pyšek and Prach 1993;Davis et al 2000;Hood and Naiman 2000;Richardson et al 2007). One may expect that if the main type of disturbance (i.e.…”

Invasions were studied at different spatial scales, however these scales were rarely compared. The aim of this study is to compare the rate of expansion of eight alien plant species within the borders of the city with expansion in the whole country and to analyse changes in distribution of these plant species in the last 30 years. We hypothesised that at the scale of the city, despite of stronger human impact, invasion processes will perform in a similar way as at the scale of whole country. Distribution changes of Bidens frondosa, Conyza canadensis, Echinocystis lobata, Helianthus tuberosus, Impatiens parviflora, Reynoutria japonica, Solidago canadensis and S. gigantea in 1 km squares grid was examined in the Warta River Valley in Poznań (W Poland) in 2013 and compared to data collected during 1980-1984. All species increased their distribution within the study area. E. lobata had the highest increment of occupied grid squares (from 0 in 1980's to 28 in 2013), and S. gigantea had the lowest (from 8 to 9). Echinocystis lobata reached the highest invasion success, which results from species traits (hydrochory) and large propagule pressure from garden plots. Between species with different ecological traits residence time has relatively little influence on invasion success, however in cases of species with similar traits (S. canadensis and S. gigantea) residence time is a crucial factor determining invasion success. Although urban ecosystems are more vulnerable to biological invasions, this process occurs in a similar way as in the whole country. This similarity is connected with similar factors responsible for spread of invasive species: propagule pressure, time since introduction and spatial distributions of invasible habitats.
