screening for antibacterial activity of some turkish plants against fish pathogens: a possible alternative in the treatment of bacterial infections.the antibacterial activity of ethanolic and aqueous crude extracts from 36 plants in turkey, including seven endemic species, against fish pathogens was studied using the disc diffusion assay. the extract that was most active against all microbial strains, except aeromonas salmonicida, was that of dorycnium pentaphyllum. some of the extracts also showed a very broad spectrum of potent antimicrobial activity. the extract of anemone nemorosa showed the highest antimicrobial activity against vibrio ...201526019642
seed consumption and dispersal of ant-dispersed plants by beech-dominated forests in central europe, many spring geophytes show adaptations to seed dispersal by ants (myrmecochory). ants, however, can be rare in such moist forests. motivated by observations of slug feeding on seeds we investigated the seed consumption of two plant species, anemone nemorosa and asarum europaeum, by slugs, in a series of experiments. in a seed predation experiment in a beech forest, we found that seed removal was strongly reduced when gastropods were excluded from the ...201020364390
experimental research on recolonisation with anemone nemorosa of the beech forests of the ruhr district (germany) floristically impoverished by air pollution.high so(2) concentrations as have been observed over decades in the ruhr district lead to a remarkable reduction of leaf area in the majority of the characteristic broad-leafed herbs of the central european beech forests even after only a few months of experimental fumigation. thus, it is no wonder in the time of high so(2) pollution, e.g., in the town of herne (centre of the ruhr district), that there was not a single beech forest hosting, for instance, viola reichenbachiana or anemone nemorosa ...200818622635

estimation of the relative importance of sexual and vegetative reproduction in the clonal woodland herb anemone nemorosa.anemone nemorosa is a perennial rhizomatous plant of european woodlands. the "probability of clonal identity" method estimated the relative proportion of sexual to vegetative reproduction in this species to be 4.4% from allozyme genotype distributions. this result is congruent with investigations on the germination, short-term demography, population genetics, and breeding system of this species, and supports the hypothesis that even low levels of seedling recruitment can maintain considerable in ...199828308475
rare earth elements in forest-floor herbs as related to soil conditions and mineral nutrition.mixtures of rare earth elements (rees) in fertilizers are widely used in chinese agriculture to improve crop nutrition. ree concentrations in wild-growing plants, especially herbs, are little known. this study describes differences in the concentrations and proportions of rees in eight forest-floor herbaceous plants and relates these differences to soil and mineral nutrient conditions. rees studied were yttrium (y), lanthanum (la), cerium (ce), praseodymium (pr), neodymium (nd), samarium (sm), e ...200516116249
plasticity in response to phosphorus and light availability in four forest herbs.the differential ability of forest herbs to colonize secondary forests on former agricultural land is generally attributed to different rates of dispersal. after propagule arrival, however, establishing individuals still have to cope with abiotic soil legacies from former agricultural land use. we focused on the plastic responses of forest herbs to increased phosphorus availability, as phosphorus is commonly found to be persistently bioavailable in post-agricultural forest soils. in a pot experi ...201020300776
a latitudinal gradient in seed nutrients of the forest herb anemone nemorosa.the nutrient concentration in seeds determines many aspects of potential success of the sexual reproductive phase of plants, including the seed predation probability, efficiency of seed dispersal and seedling performance. despite considerable research interest in latitudinal gradients of foliar nutrients, a similar gradient for seeds remains unexplored. we investigated a potential latitudinal gradient in seed nutrient concentrations within the widespread european understorey forest herb anemone ...201121489100
for she that hath, to her shall be given…implications of flowering in anemone nemorosa l.we looked for life-history trade-offs between flowering, vegetative growth and somatic maintenance in the common woodland herb anemone nemorosa. a. nemorosa forms a horizontal rhizome system consisting of previously formed annual segments and terminated by a flowering or non-flowering shoot. resources acquired by the aboveground parts are used for flowering, seed production, storage and growth of the annual segments. resources stored in the rhizome during the growing period are used for preforma ...201121973160
the response of forest plant regeneration to temperature variation along a latitudinal gradient.the response of forest herb regeneration from seed to temperature variations across latitudes was experimentally assessed in order to forecast the likely response of understorey community dynamics to climate warming.201222345113
tree litter and forest understorey vegetation: a conceptual framework to understand the effects of tree litter on a perennial geophyte, anemone nemorosa.litter is a key factor in structuring plant populations, through positive or negative interactions. the litter layer forms a mechanical barrier that is often strongly selective against individuals lacking hypocotyle plasticity. litter composition also interacts with plant growth by providing beneficial nutrients or, inversely, by allowing harmful allelopathic leaching. as conspicuous litter fall accumulation is often observed under deciduous forests, interactions between tree litter and understo ...201222419760
species, diaspore volume and body mass matter in gastropod seed feeding behavior.seed dispersal of ant-dispersed plants (myrmecochores) is a well studied ecosystem function. recently, slugs have been found to act as seed dispersers of myrmecochores. the aim of our study was to (1) further generalize the finding that gastropods feed on seeds of myrmecochores and hence may act as seed dispersers, (2) to test whether gastropod body mass and the volume of diaspores have an influence on the seed dispersal potential.201323844239
