Analyses of a sediment core from Highstead Swamp in southwestern Connecticut, USA, reveal Lateglacial and early Holocene ecological and hydrological changes. Lateglacial pollen assemblages are dominated by Picea and Pinus subg. Pinus, and the onset of the Younger Dryas (YD) cold interval is evidenced by higher abundance of Abies and Alnus viridis subsp. crispa. As climate warmed at the end of t...

In the present study, the effect of aqueous extract of Momordica dioica, aqueous extract of Myrica esculenta and ethanolic extract of Euphorbia hirta a lone and in combinat ion on h istamine induced bronchospasm in guinea p ig, milk induced leukocytosis and eosinophilia in mice and on antipruritic activity in mice was done. In the animal model o f h istamine induced bronchospasm , all plant sho...

A total of 2000 EST sequences were produced from cDNA libraries generated from Chinese bayberry fruit (Myrica rubra Sieb. and Zucc. cv. "Biqi") at four different ripening stages. After cluster and assembly analysis of the datasets by UniProt, 395 unigenes were identified, and their presumed functions were assigned to 14 putative cellular roles. Furthermore, a sequence BLAST was done for the to...

Different solvent extracts of a red algae, Hypnea flagelliformis, and two brown algae, Cystoseira myrica and Sargassum boveanum, which were collected from the Persian Gulf coast were subjected to different bioassays, including: 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging assay, antibacterial and antifungal activity by thin layer chromatography (TLC)-bioautography, agar disc dif...

BIOTIC INTERACTIONS INFLUENCING SHRUB ESTABLISHMENT ON AN ATLANTIC COAST BARRIER ISLAND. Elucidating mechanisms influencing the establishment of woody species is essential for understanding community dynamics and successional processes on barrier islands. The relative intensity of facilitation and inhibition of grasses on seedling establishment of two woody species common to Atlantic Coast barr...

We report the identification of the allelochemical 3-(1-oxo-3-phenylpropyl)-1,1,5-trimethylcyclo-hexane-2,4,6-trione, known as myrigalone A, from the fruits and leaves of Myrica gale. The structure of the compound was confirmed by high-resolution techniques (UV, MS and NMR analysis). The compound is phytotoxic towards classical plant species used for allelochemical assays and also against Fallo...
