“…This finding therefore indicates that the influence of other environmental factors on SLA variability is important for assessing the response of SLA to temperature. In particular, it suggests that trait values from existing trait databases, such as the world-wide GLOPNET (Wright et al 2004) and TRY (Kattge et al 2011) or regional LEDA (Kleyer et al 2008) and BioPOP (Poschlod et al 2003), should be used with caution in such studies, as they rarely provide any climatic, habitat or edaphic information on trait collection sites.…”

Although specific leaf area (SLA) has been proposed to reflect plant responses to climatic changes, the link between SLA and temperature has never been systematically evaluated. Using in situ measured SLA values for 223 species occurring in 29 calcareous grasslands along a temperature gradient in the Bavarian Alps, we explored the SLA-temperature relationship at population (intraspecific), species (interspecific) and community level and investigated the relative impact of other environmental factors on SLA variation along the temperature gradient at the community level. Only 14 % of the studied species showed significant changes in their SLA values along the temperature gradient, despite high intraspecific variability of the SLA values. At the species level, we revealed a very weak positive SLA-temperature relationship (r 2 = 0.04, p \ 0.001). A very strong positive correlation between SLA and temperature was detected at the community level (r 2 = 0.70, p \ 0.001). In addition to temperature, disturbance also had a significant influence on trait variation at the community level. We conclude that the variation in SLA along the temperature gradient comes primarily from changes in the relative abundances of species, whereas the trait variation at the population and the species levels was affected by other environmental factors. We therefore recommend the use of community-weighted mean values in studies employing SLA-temperature relationships because they reveal more regular patterns than the underlying distribution of within-and among-site SLA values.

“…Biomass is an important trait in growth analysis [30], where its repeated measurements are the basis for the calculations of net primary production of plants [31,32], and thus is considered a good indicator of economic yield [33,34]. Therefore differences among crop species for relative shoot dry matter production indicated that this trait can be used as reliable parameter for screening efficient cultivars [35,36].…”

The use of nutrient efficient alternative crops is a possible strategy of sustainable land use. Plant species vary in their phosphorous (P) use efficiency under suboptimal P supplies in different soils by using different strategies. Cultivating P efficient species to improve yields may be possible if P efficiency mechanisms are elucidated. Therefore P use efficiency of the alternative oil crops safflower and sunflower was studied under semicontrolled conditions in sandy and loamy soils using three P supplies. Both species responded strongly to increasing P supplies in both soils and performed better in loamy soil. In both soils, both species contained similar P concentrations in shoots at low P supplies, but safflower accumulated less P amounts in shoots than sunflower at all P levels. Sunflower had less external P requirements than safflower in both soils. Safflower had higher efficiency ratio than sunflower at low P supply in sandy soil, and less values in loamy soils. Safflower had lower utilization index than sunflower in both soils at all P levels. Safflower recovered less external P (added P, extractable-P, soil solution-P) than sunflower in both soils. The P use efficiency of crops is based on different competitive components. Neither safflower nor sunflower showed a combination of high values of all P use efficiency components in both soils at all P levels, but safflower was inferior to sunflower in most studied traits. Therefore safflower cannot be considered a low input species as compared to sunflower in terms of P uptake and utilization efficiency.

“…A set of 15 biological traits was retained (Appendix 2). The information was extracted from six plant databases: ''Biological traits of vascular plants'' (Kleyer 1995), ''Electronic comparative plant ecology'' (Hodgson et al 1995), the soil seed bank database of North West Europe (Thompson et al 1997), BIOLFLOR (Klotz et al 2002), BIOPOP (Poschlod et al 2003) and the LEDA Traitbase (Knevel et al 2003), and completed with local floras (Lambinon et al 2004;Provost 1998;Rameau et al 1989). Traits were treated as categorical variables; the optimal number of categories was defined to be ecologically meaningful and have balanced sizes (Lavorel et al 1998).…”

Impact of Prunus serotina invasion on understory functional diversity in a European temperate forest

et al. 2009

We investigated the relationships between the overstory dominance of Prunus serotina, and the functional diversity of the understory plant communities, in a managed European forest. Vegetation, habitat characteristics and disturbance history were surveyed in 32 invaded stands vs. 32 paired uninvaded stands, after a random stratification. Community specialization and functional diversity indices were compared and a RLQ analysis was run to link species traits to environmental variables. The herb layer of invaded stands exhibited significantly more specialist species and a lower trait diversity compared to uninvaded stands, with respect of species richness and vegetation cover. Light arrival to the forest floor and soil properties explained most of the variation in the RLQ analysis, but 20% of the variation strongly correlated with P. serotina dominance and associated disturbances. Traits characterizing shade-tolerant, short-living ruderals and shade-avoiders (vernal geophytes) were significantly associated to invaded stands, while those associated to light-demanding graminoids characterized uninvaded stands. The establishment of functionally close species (seedlings and saplings of native woody species) tended to be lower in invaded stands. We concluded that the invader was becoming the new ecosystem engineer, first by inducing trait convergence and community specialization, thus promoting traits that enable species to capture resources in the new environment it was creating, and second by reducing the grain of local heterogeneities.
