“…Many species with a more or less helomorph anatomy (Aegopodium podagraria, Anthriscus sylvestris, Mercurialis perennis, Urtica dioica) also have a high foliar nitrogen concentration and appear to be favoured by high nitrogen deposition. This coincides with the observation that plants cultivated under nitrogen shortage develop a more xeromorph leaf anatomy than plants cultivated on fertile soil (Müller-Stoll 1947;cited in Ellenberg 1996). In other words, increased nitrogen availability may favour an increasingly hydro-helomorph architecture.…”

Summary 1The main objective of this study was to predict the responses of vascular plant species to atmospheric nitrogen deposition and enhanced soil nitrogen levels. The study was carried out in deciduous forests located in three regions of southern Sweden. The abundance of vascular plants, as well as soil pH and nitrogen mineralization rates, were studied in a total of 661 sample plots. 2 We calculated an ecological measure ( N dev value) for all species based on their observed vs. expected nitrification ratios at a given soil pH, and compared its accuracy in predicting abundance changes with results using life history traits. Data from longterm field studies and fertilization experiments were used for validation. 3 N dev values were positively correlated between neighbouring regions. Values for the southernmost region (Skåne) were also positively related to the changes in species frequency observed in large-scale flora surveys and permanent plot studies in that area and with species changes reported from Central Europe. Values from one of two other regions were also consistent. N dev values from Skåne (but no other region) predicted species responses in short-term fertilization experiments. 4 No life history trait was as good a predictor as N dev , although plant height, leaf anatomy, leaf nitrogen concentration and phenology showed significant correlations. Attributes related to taxonomy, life form, relative growth rate and habitat type showed no agreement with the changes in species abundance. 5 We predict that species with the following attribute syndrome will increase in abundance in response to enhanced nitrogen levels: those favoured by a high soil nitrification ratio relative to other species at a given soil pH, tall stature, hydro-to helomorph anatomy, high leaf nitrogen concentration and a late phenological development.

“…In empirical studies of plant physiology, xeromorphic features have been linked to nitrogen limitation (Mothes, 1931(Mothes, , 1932Müller-Stoll, 1948), possibly as a consequence of complex physiological reactions. Nitrogen stress has been shown to reduce root water uptake; evidently because root hydraulic conductance is more limited by low nitrogen than is the hydraulic conductance of stomata (Radin and Boyer, 1982).…”

“…(7) Occasional spring frosts (Lindholm 1980;BackCus 1985). Thus it is not surprising that bog plants share many of Grime's S-selected strategy traits (Grime 1979;Backeus 1985): xeromorphy, sclerophylly and evergreenness; adaptations to tolerate low nutrient availability (Firbas 1931;Miiller-Stoll 1947;Simonis 1948;Backeus 1985;Karlsson 1985), (2) longevity (BackCus 1985), (3) low growth rate, (4) infrequent flowering and prominence of vegetative propagation in many species (Backeus 1985), (5) high ability to translocate nutrients, e.g. phosphorus (Saeb~ 1968), (6) mycorrhiza (Metsavainio 1931;Sjors 1950), and (7) insectivory .…”

A phytoecological study of the mire Northern Kisselbergmosen, SE Norway. III. Diversity and habitat niche relationships Rune H. Bkland Bkland, R. H. 1990. A phytoecological study of the mire Northern Kisselbergmosen, SE Norway. 111. Diversity and habitat niche relationships. -Nord. J. Bot. 10: 191-220. Copenhagen. ISSN 0107-055X.Alpha and beta diversity and habitat niche relationships of a poor, boreal mire was studied, based upon an ordination by detrended correspondence analysis and a subjective classification. The three first DCA axes were interpreted as variation along the following ecoclines: (1) mire expanse carpetmire expanse hummockmire margin hummock, (2) nutrient status: ombrotrophicpoor minerotrophic, and as a coenocline (3) associated with peat-producing ability of the vegetation with an unclear ecological basis. The autecology of the 39 most frequent species was decribed with respect to these gradients. Alpha diversity patterns varied considerably between coenoclines. Beta diversity was always higher in the bottom layer than in the field layer. Habitat niche breadth was strongly correlated with species abundance, and separable into a frequency-independent and a frequency-dependent component. The former decreased from vascular plants to hepatics, and further to Sphagnum spp. It was argued that the importance of interactions was high in the bottom layer, particularly among Sphagnum spp., but also among hepatics. Interactions among vascular plants was considered unimportant, except in hummocks. Plant strategies were discussed. The niche breadth approach was evaluated, and found fruitful, while niche overlap was considered to provide redundant information. The importance of each of (1) interspecific interactions, (2) destabilizing factors, (3) stress, and (4) chance, as structuring factors in boreal mires, is discussed. Boreal mires are considered to conform to the patch-dynamics theory of non-equilibrium coexistence. ~ Accepted 7-12-1989 NORD. J. BOT. 10: 191-220. GEOB 035 0 NORDIC JOURNAL OF BOTANY Nord. J.
