| imposing antecedent global change conditions rapidly alters plant community composition in a mixed-grass prairie. | global change drivers are altering climatic and edaphic conditions of ecosystems across the globe, and we expect novel plant communities to become more common as a result. in the colorado front range, compositional changes have occurred in the mixed-grass prairie plant community in conjunction with shifts in winter precipitation and atmospheric nitrogen (n) deposition. to test whether these environmental changes have been responsible for the observed plant community change, we conducted an in si ... | 2016 | 27405299 |
| [six-month follow-up of the effect of neomenor in patients with painful menstruation]. | neomenor is herbal medication especially created to permanently relieve painful menstruation symptoms in girls and women with primary dysmenorrhea. it supplies the organism with substances essential for the metabolic processes that guarantee normal menstrual cycles. in some women these substances are out of balance, there is an excess of prostaglandins, which leads to painful periods, menstrual cramps and even migraine. each neomenor tablet contains 400 mg of standardized extracts from stalks of ... | 2011 | 21695945 |
| interferonogenic and antiviral effect of extracts from erodium cicutarium. | extracts from erodium cicutarium l. herit were tested for antiviral and interferon inducing properties. both water extract and methanol extract as well as its fractions were observed to exert antiviral effect in relation to myxoviruses, herpes virus type 1, vesicular stomatitis and vaccinia virus. none of these extracts did induce interferon in a suspension of human leukocytes. | 1987 | 3128960 |
| interferonogenic and antiviral effect of extracts from erodium cicutarium. ii. modulatory activity of erodium cicutarium extracts. | methanol extract from erodium cicutarium was shown not to induce interferon in a suspension of human leukocytes or in the cutaneo-muscular tissue of human embryo. it appeared to have no influence, either direct or cell-mediated, on interferon activity. however, it exerted stimulatory effect on the synthesis of interferon induced with newcastle disease virus in cell cultures. the stimulation occurred irrespective of the time of methanol extract administration (before or after viral inducer). in t ... | 1988 | 2478099 |
| identification and characterization of the water gap in physically dormant seeds of geraniaceae, with special reference to geranium carolinianum. | physical dormancy in seeds of species of geraniaceae is caused by a water-impermeable palisade layer in the outer integument of the seed coat and a closed chalaza. the chalazal cleft has been reported to be the water gap (i.e. location of initial water entry) in innately permeable seeds of geraniaceae. the primary aim of this study was to re-evaluate the location of the water gap and to characterize its morphology and anatomy in physically dormant seeds of geraniaceae, with particular reference ... | 2010 | 20400757 |
| characterizing selection on phenotypic plasticity in response to natural environmental heterogeneity. | adaptive genetic differentiation and adaptive phenotypic plasticity can increase the fitness of plant lineages in heterogeneous environments. we examine the relative importance of genetic differentiation and plasticity in determining the fitness of the annual plant, erodium cicutarium, in a serpentine grassland in california. previous work demonstrated that the serpentine sites within this mosaic display stronger dispersal-scale heterogeneity than nonserpentine sites. we conducted a reciprocal t ... | 2010 | 20649815 |
| the mechanics of explosive dispersal and self-burial in the seeds of the filaree, erodium cicutarium (geraniaceae). | the filaree (erodium cicutarium), a small, flowering plant related to geraniums, possesses a unique seed dispersal mechanism: the plant can fling its seeds up to half a meter away; and the seeds can bury themselves by drilling into the ground, twisting and untwisting in response to changes in humidity. these feats are accomplished using awns, helical bristles of dead but hygroscopically active tissue attached to the seeds. here, we describe the kinematics of explosive dispersal and self-burial b ... | 2011 | 21270299 |
| linking the spatial scale of environmental variation and the evolution of phenotypic plasticity: selection favors adaptive plasticity in fine-grained environments. | adaptive phenotypic plasticity and adaptive genetic differentiation enable plant lineages to maximize their fitness in response to environmental heterogeneity. the spatial scale of environmental variation relative to the average dispersal distance of a species determines whether selection will favor plasticity, local adaptation, or an intermediate strategy. habitats where the spatial scale of environmental variation is less than the dispersal distance of a species are fine grained and should fav ... | 2011 | 21670579 |
| seed selection by the harvester ant pogonomyrmex rugosus (hymenoptera: formicidae) in coastal sage scrub: interactions with invasive plant species. | harvester ants can be the dominant seed predators on plants by collecting and eating seeds and are known to influence plant communities. harvester ants are abundant in coastal sage scrub (css), and css is frequently invaded by several exotic plant species. this study used observations of foraging and cafeteria-style experiments to test for seed species selection by the harvester ant pogonomyrmex rugosus emery (hymenoptera: formicidae) in css. analysis of foraging behavior showed that p. rugosus ... | 2016 | 27257121 |

| resource allocation of chilean herbs in response to climatic and microclimatic factors. | resource allocation to aerial vegetative, underground vegetative, and reproductive biomass is studied in four chilean herbs: the annuals chaetanthera ciliata, erodium cicutarium, trisetobromus hirtus, and the perennial solenomelus peduncularis. absolute (weight), and relative (% vegetative/total, % root/shoot) changes in biomass were determined in relation to concomitant changes in a climatic (rain regime in two subsequent years) and a microclimatic factor (spatial distribution of herbs, whether ... | 1979 | 28309605 |
| interactions among unrelated species: granivorous rodents, a parasitic fungus, and a shared prey species. | granivorous rodents and a parasitic fungus in the sonoran desert utilize a common prey species, erodium cicutarium, a desert annual plant. experimental removal of rodents from field exclosures resulted in significantly higher densities of e. cicutarium. fungal infection was significantly higher in the absence of rodents, suggesting that, while they do not interact directly, rodents and the fungus affect each other's densities by their use of a common prey species. | 1981 | 28310009 |
| antioxidative effect of extracts from erodium cicutarium l. | extracts from erodium cicutarium l. (ec) and some standard substances present in ec extracts were tested for their antioxidative properties during fe(2+)-induced triglyceride oxidation. hydrophobic fractions such as petroleum ether (pee), benzene (be) and chloroform i (che i) extracts as well as hydrophilic fractions i.e. water (we) and ethyl acetate (eae) showed an antioxidative effect. among the tested substances vitamin c and some polyphenolic compounds: tannin, (+)-catechin and gallic acid e ... | 2013 | 7865033 |
| phenolic acids and depsides from some species of the erodium genera. | six natural polyphenolic compounds, brevifolin carboxylic acid, brevifolin, ellagic acid, methyl gallate, gallic acid and protocatechuic acid have been isolated from the methanol extract of the whole plant of erodium cicutarium (l.) l.'hérit. (geraniaceae). structures were determined by conventional methods of analysis and confirmed by ms and nmr spectral analysis. the distribution of these compounds in the other species of the erodium genera (e. botrys, e. chium, e. ciconium, e. cicutarium, e. ... | 2012 | 11837680 |
| understanding the consequences of seed dispersal in a heterogeneous environment. | plant distributions are in part determined by environmental heterogeneity on both large (landscape) and small (several meters) spatial scales. plant populations can respond to environmental heterogeneity via genetic differentiation between large distinct patches, and via phenotypic plasticity in response to heterogeneity occurring at small scales relative to dispersal distance. as a result, the level of environmental heterogeneity experienced across generations, as determined by seed dispersal d ... | 2009 | 19739374 |
| niche opportunities and invasion dynamics in a desert annual community. | although many factors influence the ability of exotics to invade successfully, most studies focus on only a few variables to explain invasion; attempts at theoretical synthesis are largely untested. the niche opportunities framework proposes that the demographic success of an invader is largely affected by the availability of resources and the abundance of its enemies. here, we use a 31-year study from a desert ecosystem to examine the niche opportunities framework via the invasion of the annual ... | 2013 | 23126368 |
| high water-use efficiency and growth contribute to success of non-native erodium cicutarium in a sonoran desert winter annual community. | the success of non-native, invasive species may be due to release from natural enemies, superior competitive abilities, or both. in the sonoran desert, erodium cicutarium has increased in abundance over the last 30 years. while native species in this flora exhibit a strong among-species trade-off between relative growth rate and water-use efficiency, e. cicutarium seems to have a higher relative growth rate for its water-use efficiency value relative to the pattern across native species. this no ... | 2014 | 27293627 |
