-Relevés from meadows and pastures of South Transdanubia (Hungary) are evaluated by clustering and ordination methods. The relevé selection focused on the Arrhenatheretalia order but its transitions towards other types were also included. The groups of relevés are delimited and described according to differential, dominant and constant species. Ecological conditions of the groups were compared using indicator values. Nine groups were distinguished, four of them belonging strictly to the order Arrhenatheretalia. Each alliance of Arrhenatheretalia presented in the study area (Cynosurion, Arrhenatherion) was represented by two groups. Groups from these two alliances are separated along a light gradient, while groups of the same alliance differ in nutrient values. Within Cynosurion, the nutrient-poor group cannot be identified unambiguously as any syntaxa previously known from Hungary. The nutrient-rich Cynosurion meadows are similar to Lolio-Cynosuretum, however, they show a stronger relationship with wet meadows. Within Arrhenatherion, Pastinaco-Arrhenatheretum is recognised as a hay meadow of nutrient-rich soils. The other meadow type is similar to Filipendulo-Arrhenatheretum, thus raising syntaxonomical problems. There are transitional groups towards semi-dry and wet meadows, one dynamic phase and one outlier group among the other five clusters.

“…Riparian annuals like Chenopodium glaucum and Digitaria sanguinalis are fastgrowing, widespread summer-annual weeds that show high phenotypic plasticity to changes in environmental conditions (Wulff et al 1999;Huang et al 2000;Rajcan et al 2002;Causin and Wulff 2003). Both have intermediate strategies between R and C-R (C, S and R are short for competitive, stress-tolerant and ruderal respectively) in the established phase, according to Grime's C-S-R model (Grime et al 1988;Zelnik and Č arni 2008). Most annuals (both hydric and mesic species) complete their life cycle during late summer rain at seasonal flow sites, which feature inflowing groundwater or surface flow that moisten disturbed fluvial surfaces in riparian zones .…”

Effects of hydrologic modifications to riparian plant communities in a large river system in northern China

Hydrologic modifications to rivers caused by anthropogenic activity have major impacts on riparian ecosystems. Alterations to the hydrologic regime and their interactions with natural environmental parameters exert selective pressures on riparian vegetation, resulting in adaptations to specific flow attributes. However, few studies have attempted to detect these effects under multiple hydrologic conditions, especially for rivers in semi-dry and semi-humid regions. Using the ''space-for-time substitution'' method, we investigated the effects of hydrologic modifications to the riparian plant community along the Yongding River of northern China, by comparing community structure metrics (diversity, plant moisture affinity group, and lifespan) and a function metric (biomass) under three streamflows (perennial, seasonal and dried-up). Among these streamflows, seasonal flow reaches had the greatest plant diversity. Responses of plant moisture group and lifespan were inconsistent in different hydrologic stages, although they varied significantly (P < 0.01). Annuals and biennials greatly increased from perennial to seasonal streamflow ($59 %), while perennials decreased ($41 %). However, from seasonal to dried-up flow, the percentage of mesics and xerics increased by 12.8 and 11.8 %, respectively, while hydrics decreased dramatically (by 24.6 %). Perennial flow had significantly greater aboveground biomass (P < 0.05) than the other two flows. Hydrologic conditions and their related soil nutrients were the main driving factors of community structure and function, which explained 21.0 and 18.0 % of variation, respectively. These findings reveal the response process of the riparian plant community during hydrologic modification from perennial to dried-up streamflow.

“…While the use of ecological strategies is quite common in studies of herbaceous vegetation (Hunt et al 2004, Zelnik and Čarni 2008, Škornik et al 2010, Pipenbaher et al 2013, it has lately also been gaining ground in the study of forest and woodland communities (Kilinç et al 2010, Paušič and Čarni 2012, Juvan et al 2013, Košir et al 2013b, Rozman et al 2013). Its use is most often related to studies of changes in communities' composition as a response to disturbance, succession, environmental changes or in gradient analysis.…”

-Zonal vegetation is a large-scale expression of macro-climate and, due to the climatic diversity of the country, there are seven traditionally recognized zonal forest plant communities in Bosnia and Herzegovina. Using data from Bosnia and Herzegovina, this study aimed to reveal whether macro-climate is indeed the most important factor determining the existence of zonal forest plant communities (ZFPC). Detrended correspondence analysis of 398 relevés of seven ZFPCs revealed that the species turnover along the fi rst axis is strongly related to the macro-climatic gradient (annual mean temperature, mean temperature of the coldest quarter and precipitation of the warmest quarter). No correlation was detected between this gradient and topographic factors (slope and aspect) and soil reaction. Floristic analysis revealed clear separation of ZFPCs in terms of diagnostic species. Functional analysis of all layers showed that competitive ecological strategy has the highest proportion, while analysis of the herb layer alone expressed a shift of CSR signatures towards the middle of the C-S axis. Ruderality was overall poorly expressed. Statistically signifi cant differences among communities were discovered along the C-S axis. In terms of life forms, statistically signifi cant differences in the proportions of Phanerophytes, Geophytes and Hemicryptophytes among communities were discovered. Our study confi rms that macro-climatic gradient is the most important determinant of the species turnover along ZFPCs. CSR signatures show that zonal forest vegetation is represented by productive communities in a terminal stage of succession. This does not refer to degraded Quercus ilex stands (maquis), which are in the middle stage of secondary succession.
