Many exotic plant invaders pose a serious threat to native communities, but little is known about the dynamics of their impacts over time. In this study, we explored the impact of an invasive plant Heracleum mantegazzianum (giant hogweed) at 24 grassland sites invaded for different periods of time (from 11 to 48 years). Native species' richness and productivity were initially reduced by hogweed...

Heracleum is the widest genera of Apiaceae family. Of more than 120 species, 25 are presented in Caucasus, while 23 distributed to Georgia, from which 5 species endemic. According literature, only 1/6 of Heracleum species have been studied phytochemically so far. Plants this genus contain aromatic compounds and considered be a very rich source essential oils diverse furanocoumari...

This study reports the isolation and polymorphism characterization of four plastid indels and six nuclear microsatellite loci in the invasive plant Heracleum mantegazzianum . These markers were tested in 27 individuals from two distant H. mantegazzianum populations. Plastid indels revealed the presence of five chlorotypes while five nuclear microsatellite loci rendered polymorphism. Application...

The impact of invasion on diversity varies widely and remains elusive. Despite the considerable attempts to understand mechanisms of biological invasion, it is largely unknown whether some communities' characteristics promote biological invasion, or whether some inherent characteristics of invaders enable them to invade other communities. Our aims were to assess the impact of one of the massive...

Essential oils from Ferulago asparagifolia Boiss., F. galbanifera (Miller) W. Koch, F. humilis Boiss. (Endemic), F. trachycarpa Boiss. growing in Turkey were evaluated against 15 microorganisms for their antifungal and antibacterial activity using an agar tube dilution and microdilution broth susceptibility assay, respectively. The essential oil compositions were investigated by GC/MS. Inhibito...

BACKGROUND AND OBJECTIVE: Emergence of resistant microbial strains due to the consumption of chemical preservatives and medications, as well as uncertainty about the consumption of foods containing synthetic preservatives, have resulted in the growing popularity of natural preservatives. This study aimed to identify the chemichal compounds found in the essence of Persian hogweed (Heracleum pers...

Occurrences of the invasive plant species Heracleum sosnowskyi Manden. in the Komi Republic (northeastern part of European Russia) were recorded and published in the Global Biodiversity Information Facility (GBIF http://www.gbif.org) using the RIVR information system (http://ib.komisc.ru/add/rivr/en). RIVR stands for "Rasprostranenie Invasionnyh Vidov Rastenij" [Occurrence of Invasion Plant Spe...

OBJECTIVE This study was designed to investigate the effect of hydroalcoholic extract and essential oil of Heracleum persicum (Apiaceae) on lipid profile of male hyperlipidemic rabbits. MATERIALS AND METHODS Thirty rabbits were randomly divided into six groups of five each. One group received normal diet and the other groups fed with a high cholesterol (2% W/W) diet for 7 weeks. Vehicle, hydr...
