These paper deals with 45 taxa, seven of which are new to the Balearic Islands flora: Agrostis capillaris L., Centaurea solstitialis L. Chenopodium strictum Roth, Datura wrigthii Regel, Kickxia elatine (L.) Dumort. subsp. elatine, Ranunculus xatardii Lapeyr. and Senecio inaequidens DC. On the other hand, six taxa [Catananche caerulea L., Centaurea apula Lam., Filago micropodioides Lange, Legous...

In the search for new sources of sesquiterpene lactones, six Centaurea species have been analyzed. The activity against the fungus Cunninghamella echinulata of (+)-cnicin (1) and (+)-salonitenolide (2), isolated from the Centaurea plants, as well as that of (+)-costunolide (3), (-)-dehydrocostuslactone (4), (-)-lychnopholide (5) and (-)-eremantholide C (6), has been evaluated. Compounds 3 and 4...

Human modification of the environment is causing both loss of species and changes in resource availability. While studies have examined how species loss at the local level can influence invasion resistance, interactions between species loss and other components of environmental change remain poorly studied. In particular, the manner in which native diversity interacts with resource availability...

In this study, it was investigated the total amounts of phenolic and flavonoid substances antioxidant activities in different solvent extracts Lonicera iberica M. Bieb. wild fruit. Total contents were determined as equivalent to gallic acid using Folin-Ciocalteu reagent, quercetin by aluminium nitrate method. addition, properties free radical scavenging (DPPH) reducing power (FRAP) methods. The...

to evaluate the effect of water stress on yield and water use efficiency (wue) of lallemantia sp, an experiment was conducted as split plot factorial in randomized complete block design with three replications in the field of medicinal plants research center of shahed university, tehran in 1390-91. the first factor was irrigation system including 40 and 60 percent depletion of available soil wa...

Nine species of Palaearctic Myrmillinae with females bearing two round spots on the second metasomal tergite, currently assigned to two genera, Blakeius Ashmead, 1903 and Liomutilla André, 1907, are revised and their phylogenetic relationships are investigated. The cladistic analyses demonstrate that Blakeius is not strictly monophyletic but includes three distinct lineages: Blakeius s. str., c...
