“…Accordingly, although our plant indicator species may to some extent be associated to potential natural plant communities, the reference to single species is more pertinent, as recommended by Rosenthal (2003). Moreover, plant indicator species selected by Indicator Value analysis consists of a list of species significantly associated with each target group of sampling plots, which does not mean that the species must co-occur in the same location (de Cáseres et al, 2012).…”

“…Unfortunately, taxonomic diversity and vulnerability of species to extinction (Red Lists) are the only measures routinely taken into account in many biodiversity monitoring programs (Vandewalle et al, 2010). However, vulnerable species are often too rare to be considered the only important plant species when determining ecological quality (Rosenthal, 2003). In fact, in a survey carried out in Austrian meadows, Zechmeister et al (2003) concluded that Red List species are not appropriate in evaluating intensively used agricultural meadows; moreover the authors observed no correlation between the amount of subsidies and plant species richness in the investigated meadows.…”

a b s t r a c tIt is widely accepted that the concept of biodiversity embraces two essential and complementary components: taxonomic and functional diversity. Our goal is to produce a list of plant species predictive of high taxonomic and functional biodiversity values and discuss their use within biodiversity monitoring programmes. We selected a representative sample of 48 vineyard areas from Southern Switzerland, and vegetation from the ground cover was sampled from within a total of 120 sampling plots. We considered ten widely used functional traits and selected six taxonomic and functional indices. We applied a two-step analysis: (i) using Threshold Indicator Taxa Analysis (TITAN) based on the above mentioned biodiversity indices, we defined 3 groups of sampling plots with low (L), medium (M) and high (H) biodiversity values; (ii) using the Indicator Value analysis, we identify indicator species that are significantly associated with the above-mentioned groups and their combinations. In total, 259 vascular plants were identified across the sampling plots. As a whole, 52 species were significant indicators for groups with high and mid-to-high biodiversity values. Out of all indicator species, 24 (46%) were exclusively selected by functional biodiversity indices whereas only 10 (19%) were associated with taxonomic indices. Eighteen (35% of the total) species were selected by both types of indices. We point out that indicator species associated with two different aspects of biodiversity show a high degree of complementarity. Our results emphasize the need to consider functional aspects of biodiversity in diversity-conservation strategies when the objectives are to preserve both taxonomic diversity and ecosystem functioning.

“…One of the most important functions worth saving is the ability of wetlands to store and clean water. Major restoration concepts along these lines include ceasing agriculture and re-establishment of wetland hydrology (Rosenthal 2003). Since wetlands are by definition permanently or temporarily flooded areas, raising the water table to original levels is thus the first step for a wetland revival.…”

Wetland restoration and methanogenesis: the activity of microbial populations and competition for substrates at different temperatures

Abstract. Ljubljana marsh in Slovenia is a 16 000 ha area of partly drained fen, intended to be flooded to restore its ecological functions. The resultant water-logging may create anoxic conditions, eventually stimulating production and emission of methane, the most important greenhouse gas next to carbon dioxide. We examined the upper layer (∼30 cm) of Ljubljana marsh soil for microbial processes that would predominate in water-saturated conditions, focusing on the potential for iron reduction, carbon mineralization (CO 2 and CH 4 production), and methane emission. Methane emission from water-saturated microcosms was near minimum detectable levels even after extended periods of flooding (>5 months). Methane production in anoxic soil slurries started only after a lag period of 84 d at 15 • C and a minimum of 7 d at 37 • C, the optimum temperature for methanogenesis. This lag was inversely related to iron reduction, which suggested that iron reduction out-competed methanogenesis for electron donors, such as H 2 and acetate. Methane production was observed only in samples incubated at 14-38 • C. At the beginning of methanogenesis, acetoclastic methanogenesis dominated. In accordance with the preferred substrate, most (91%) mcrA (encoding the methyl coenzyme-M reductase, a key gene in methanogenesis) clone sequences could be affiliated to the acetoclastic genus Methanosarcina. No methanogens were detected in the original soil. However, a diverse community of iron-reducing Geobacteraceae was found. Our results suggest that methane emission can remain transient and low if water-table fluctuations allow reoxidation of ferrous iron, sustaining iron reduction as the most important process in terminal carbon mineralization.

“…Twelve springs types are recognized, not including paleo-springs (Springer and Stevens 2009 The phyto-sociological part was worked out with the help of the Zürich Montpellier School of Phytosociology and included analysis, synthesis and identifying vegetation. Sixteen phytosociological relevés were taken (Rosenthal, 2003). The vegetation plot size was delimited in such a way as to represent full floristic composition of the phyto-coenosis.…”
