Contaminant exposure can vary between species but primary causes of it are often unclear. In order to estimate heavy metal intake of two sympatric passerines - Ficedula hypoleuca Pall. and Parus ater L. - we studied nestling diet and metal concentrations in prey invertebrates, near the Middle Ural copper smelter and in an unpolluted area. Diet of P. ater contained more Cu, Cd and Zn compared to...

To investigate the genetic diversity and phylogenetic relationships of Salvia miltiorrhiza and related species, we analyzed the nuclear ribosomal DNA internal transcribed spacer (ITS) region for 7 accessions of Salvia miltiorrhiza and another 23 samples from other taxa within the genus Salvia by maximum parsimony and Bayesian inference analyses. Th ere were 257 variation sites amounting to 40.8...

Five new spirobifuranocoumarins, dahuribirins A-E (1-5) and two new bifuranocoumarins, dahuribirins F and G (6 and 7) were isolated from Japanese Bai Zhi (the root of Angelica dahurica Benth. et Hook. var. dahurica Benth. et Hook.) and their structures were established by chemical and spectral means.

BACKGROUND AND AIMS The genus Salvia has traditionally included any member of the tribe Mentheae (Lamiaceae) with only two stamens and with each stamen expressing an elongate connective. The recent demonstration of the non-monophyly of the genus presents interesting implications for staminal evolution in the tribe Mentheae. In the context of a molecular phylogeny, the staminal morphology of the...

Salvia divinorum (salvia) is an intense, short-acting hallucinogenic plant gaining popularity among adolescents in the United States. There has been little scientific documentation of salvia's effects. The popular video-sharing website YouTube has received literally thousands of video-posts of people using salvia. The objective of this study was to assess the effects of salvia use through syste...
