Moist and temperate Caspian forests are associated with a diversity of soil types and topography.  Although, natural history and ecological attributes of the Caspian vegetation is well-documented, little is known about mycorrhizae of the Caspian (Hyrcanian) flora. Samples of herbaceous plant species were collected from 4 pre-determined altitudes (-13 upto about 1500m above sea level, appro...

Marginal croplands, such as those in the Conservation Reserve Program (CRP), have been suggested as a source of biomass for biofuel production. However, little is known about the composition of plant species on these conservation grasslands or their potential for ethanol production. Our objective was to assess the potential of CRP and other conservation grasslands for biofuel production, descri...

Semi-natural dry grassland sites are of great importance for nature conservation because they support high species diversity and the abundance of "Red-List" species. Grazing has proved to be a successful management tool in terms of maintenance and restoration of biodiversity. For a deeper understanding of the effects of different grazers on species biodiversity in dry grasslands, it is necessar...

Two species belonging to the genus Salvia (Salvia brachyodon Vandas and Salvia officinalis L.) from Dalmatian region were studied for their essential oil composition, genome size and base composition. These species showed the same chromosome number (2n 1⁄4 14), similar genome size (0.95 and 0.97 pg/2C) and base composition (38.52 and 38.55 GC%), respectively. This is the first estimation of DNA...
