The change in phosphorus and nitrogen content in a common geophyte spring species, Allium ursinum, is studied in alluvial forests in relation to three flooding histories related to river regulation: (1) annually flooded, (2) unflooded for 30 years, and (3) unflooded for 200 years. Flood suppression leads to a reduction of available P soil content as well as decreasing the biomass and the amount of phosphorus in plants, but has no significant effect on N plant content. Plant N:P ratio increases… Expand

Soil Humus, Iron, Sulphate and Magnesium Content Affect Nectar Traits of Wild Garlic (Allium ursinum L.)
This study intended to reveal which soil properties had the most powerful impact on nectar variables of wild garlic (Allium ursinum L.), and suggested that in addition to the effect of microclimatic factors, certain soil properties can have significant impact onNectar traits. Expand
Floodplain capacity to depollute water in relation to the structure of biological communities
Abstract Floodplains are complex ecological systems that are mostly regulated by river dynamics and human disturbances that determine the efficiency of the coupling of hydrogeochemical functions andExpand
Multi-scale analysis of environmental constraints on macrophyte distribution, floristic groups and plant diversity in the Lower Paraná River floodplain
Abstract The Parana River floodplain comprises one of the largest wetland systems of South America. In a sector of the Lower Parana River floodplain (100 km length, 3650 km 2 ), floristic compositionExpand
Population ecology of Allium ursinum, a space-monopolizing clonal plant
It is concluded that A. ursinum has a distinct, hitherto non-described, strategy for monopolizing space and dominating the forest floor using the Clan-of-Clones strategy. Expand

Effect of a dense Allium ursinum (L.) ground cover on nutrient dynamics and mesofauna of a Fagus sylvatica (L.) woodland
The aboveground biomass built up annually by Allium ursinum (L.) contains similar amounts of nutrients as the foliage of mature Fagus sylvatica (L.), and substantial amounts of nitrogen are lost from the system. Expand
Impact of river management history on the community structure, species composition and nutrient status in the Rhine alluvial hardwood forest
The present-day Rhine alluvial hardwood forest (Querco-Ulmetum minoris, Issler 24) in the upper Rhine valley (France/Germany) is comprised of three vegetation units, one still flooded by calm watersExpand
Foliar nutrient dynamics and nutrient use efficiency of four deciduous tree species in relation to site fertility
Seasonal foliar nutrient dynamics of four deciduous forest tree species exhibited physiological plasticity which allowed maintenance of relative growth rates, despite low soil nutrient availability, by increasing the efficiency of nutrient use. Expand
Soil fertility in a large dryland floodplain: Patterns, processes and the implications of water resource development
Abstract 1. Primary production on semiarid floodplains supports a diverse local and regional fauna. Reduced flooding from water resource development (WRD) may affect floodplain production byExpand
Foliar nutrient dynamics and resorption in naturalized Lonicera Maackii (Caprifoliaceae) populations in Ohio, USA
The hypothesis that foliar resorption is greater in forested sites with lower P fertility is supported, however, resOrption rates for N did not support the hypothesis clearly, as slopes with intermediate N availability had greater N Resorption rates than did N-rich bottomlands. Expand
Soil water status influences plant nitrogen use: a case study

Regional differences in nutrient limitation in floodplains of selected European rivers: implications for rehabilitation of characteristic floodplain vegetation
Extremely high river discharges in 1993 and 1995 along the Dutch rivers Rhine and Meuse have increased the public awareness of possible safety threats. As a result the ‘Space for Rivers’ program wasExpand
The effects of enhanced nutrient availability on the rate of nutrient cycling, feed-back between plant processes and nutrient availability and soil carbon and nutrient storage, in two English riverine ecosystems with a different fertilization history were investigated. Expand
Rapid Nitrate Loss and Denitrification in a Temperate River Floodplain
Nitrogen (N) pollution is a problem in many large temperate zone rivers, and N retention in river channels is often small in these systems. To determine the potential for floodplains to act as NExpand
Changes in nitrogen resorption traits of six temperate grassland species along a multi-level N addition gradient
It is suggested that long-term N fertilization increased N uptake and decreased N- Resorption proficiency, but the effects on N-resorption efficiency were species-specific for different temperate grassland species in northern China. Expand
