| antennal responses to floral scents in the butterfly heliconius melpomene. | floral scent, together with visual floral cues, are important signals to adult butterflies searching for food-rewarding plants. to identify which compounds in a floral scent are more attractive and, thus, of biological importance to foraging butterflies, we applied electrophysiological methods. antennal responses of male and female adults of the tropical butterfly heliconius melpomene l. (lepidoptera: nymphalidae: heliconiinae) to individual compounds of natural floral scents and synthetic flora ... | 2003 | 14682514 |
| on the perils of mycorrhizal status lists: the case of buddleja davidii. | one observation in a mycorrhizal check-list that buddleja davidii is nonmycorrhizal has been perpetuated in subsequent citations and used in a number of analyses of mycorrhizal ecology and evolution. direct observation of b. davidii from new zealand and the uk shows extensive arbuscular mycorrhizal fungal structures inside b. davidii roots. the suggestion that b. davidii is nonmycorrhizal is therefore not supported. the use of mycorrhizal checklists for analysis of plant traits and evolution nee ... | 2007 | 17805583 |
| biomass characterization of buddleja davidii: a potential feedstock for biofuel production. | a compositional analysis was performed on buddleja davidii to determine its general biomass characteristics and provide detailed analysis of the chemical structures of its cellulose and lignin using nmr. b. davidii is a new potential lignocellulosic bioresource for producing bioethanol because it has several attractive agroenergy features. the biomass composition of b. davidii is 30% lignin, 35% cellulose, and 34% hemicellulose. solid-state cp/mas (13)c nmr showed that 33% of the cellulose is pa ... | 2009 | 19170631 |
| variability among species in the apoplastic ph signalling response to drying soils. | after the imposition of soil drying treatments, an elevation of xylem sap ph is one of the earliest observable responses in many herbaceous model plant species. it is theorized that alkalization of sap results in a concurrent elevation in abscisic acid (aba) concentration delivered to transpiring tissues by preventing henderson-hasselbalch-regulated partitioning between the apoplast and symplast. however, here it is demonstrated that the sap alkalzation response to soil drying is far from univer ... | 2009 | 19726633 |
| 'the child that tiire doesn't give you, god won't give you either.' the role of rotheca myricoides in somali fertility practices. | the paper introduces the baanashada dumarka, a somali fertility therapy carried out by a spirit medium, known locally as 'alaqad. baanashada is aimed at women whose fertility issues are believed to be caused by spirits. the study also explores a component of the baanashada, namely, the use of tiire (rotheca myricoides), or the butterfly bush. although rotheca myricoides is known to possess a number of medicinal components as confirmed by studies of modern science, so far, there exist no studies ... | 2016 | 27830941 |
| floral scent composition predicts bee pollination system in five butterfly bush (buddleja, scrophulariaceae) species. | traditionally, plant-pollinator interactions have been interpreted as pollination syndrome. however, the validity of pollination syndrome has been widely doubted in modern studies of pollination ecology. the pollination ecology of five asian buddleja species, b. asiatica, b. crispa, b. forrestii, b. macrostachya and b. myriantha, in the sino-himalayan region in asia, flowering in different local seasons, with scented inflorescences were investigated during 2011 and 2012. these five species exhib ... | 2015 | 24841694 |
| differential attraction of aedes albopictus in the field to flowers, fruits and honeydew. | sugar is the main source of energy for the activities of mosquitoes; however, information on the vital sugar feeding of aedes albopictus in the field is scanty and often anecdotal. using glue traps and baits, we evaluated the attraction of ae. albopictus to 28 different, potential sugar sources. control traps were baited with either sugar-water solution or water alone, and since there was no significant difference between these controls, the water control was used as the standard for comparison. ... | 2011 | 21310142 |
| aedes albopictus (diptera: culicidae) oviposition preference as influenced by container size and buddleja davidii plants. | aedes albopictus (skuse) is a container-breeding mosquito commonly found in residential areas of its range in the united states. mosquitoes are known to utilize flowering plants for sugar acquisition. limited information is known about the influences on oviposition site selection, outside of container size. residential areas are often landscaped with a variety of flowering plants and are known to provide numerous sizes of potential larval developmental sites for container-breeding mosqutioes. th ... | 2016 | 26733402 |

| neuroprotective effects of linarin through activation of the pi3k/akt pathway in amyloid-β-induced neuronal cell death. | linarin, a natural occurring flavanol glycoside derived from mentha arvensis and buddleja davidii is known to have anti-acetylcholinesterase effects. the present study intended to explore the neuroprotective effects of linarin against aβ(25-35)-induced neurotoxicity with cultured rat pheochromocytoma cells (pc12 cells) and the possible mechanisms involved. for this purpose, pc12 cells were cultured and exposed to 30 μm aβ(25-35) in the absence or presence of linarin (0.1, 1.0 and 10 μm). in addi ... | 2011 | 21652214 |
| antioxidant phenylpropanoid glycosides from buddleja davidii. | phytochemical investigations on the n-buoh-soluble fraction of the whole plant of buddleja davidii led to the isolation of the phenylpropanoid glycosides 1-10. their structures were determined by 1d and 2d nmr spectroscopic techniques. all the compounds showed potent antioxidative activity in three different tests, with ic(50) values in the range 4.15-9.47 microm in the hydroxyl radical ( oh) inhibitory activity test, 40.32-81.15 microm in the total ros (reactive oxygen species) inhibitory activ ... | 2009 | 19548780 |
| invasive buddleja davidii allocates more nitrogen to its photosynthetic machinery than five native woody species. | the general-purpose genotype hypothesis and the hypothesis of the evolution of invasiveness predict that invasive species are characterized by particular traits that confer invasiveness. however, these traits are still not well-defined. in this study, ecophysiological traits of eight populations of the invasive shrub buddleja davidii from a wide range of european locations and five co-occurring native woody species in germany were compared in a common garden experiment. we hypothesized that the ... | 2007 | 17534664 |
| correlation between anatomical characteristics of ethanol organosolv pretreated buddleja davidii and its enzymatic conversion to glucose. | buddleja davidii is a unique biomass that has many attractive agroenergy features, especially its wide range of growth habitat. the anatomical characteristics of b. davidii were investigated before and after ethanol organosolv pretreatment (one of the leading pretreatment technologies) in order to further understand the alterations that occur to the cellular structure of the biomass which can then be correlated with its enzymatic digestibility. results showed that the ethanol organosolv pretreat ... | 2010 | 20672330 |

| vegetative regeneration capacities of five ornamental plant invaders after shredding. | vegetation management often involves shredding to dispose of cut plant material or to destroy the vegetation itself. in the case of invasive plants, this can represent an environmental risk if the shredded material exhibits vegetative regeneration capacities. we tested the effect of shredding on aboveground and below-ground vegetative material of five ornamental widespread invaders in western europe that are likely to be managed by cutting and shredding techniques: buddleja davidii (butterfly bu ... | 2015 | 25387455 |
| linarin inhibits the acetylcholinesterase activity in-vitro and ex-vivo. | linarin is a flavone glycoside in the plants flos chrysanthemi indici, buddleja officinalis, cirsium setosum, mentha arvensis and buddleja davidii, and has been reported to possess analgesic, antipyretic, anti-inflammatory and neuroprotective activities. in this paper, linarin was investigated for its ache inhibitory potential both in-vitro and ex-vivo. ellman's colorimetric method was used for the determination of ache inhibitory activity in mouse brain. in-vitro assays revealed that linarin in ... | 2015 | 26330885 |
