Crassulacean acid metabolism (CAM) is common in several plant families and is often associated with succulence. Few studies have examined the occurrence of CAM from a phylogenetic perspective. The genus Pelargonium is promising for such a study because members are characterized by dramatic variation in growth form (including geophytes, shrubs, and stem succulents) and because growth form divers...

The diversity of early spring vascular fl ora was studied in the Sub-Pannonic steppic grassland in the village of Bilje, north eastern Croatia. In all, 109 plant taxa within 35 families were found. The highest number of taxa belongs to the families Poaceae, Fabaceae, Asteraceae, Caryophyllaceae, Lamiaceae and Rosaceae. Specifi c habitat conditions, characterized by moderately wet and moderately...

Floristic studies are fundamental for the applied sciences such as rangelandmanagement and conservation. Unique ecological and climatic conditions in the NorthernKhorasan Province (NKP) make it a remarkable habitat for the floristic studies. Plant specieswere collected from 50 field sites, representing major habitats of winter and rural rangelands.Surveys were conducted during active growth per...

Global climate change has unforeseeable ramifications for the ecosystem of our home planet. In Europe, more than half vascular plant flora may become endangered by year 2080 as a result climatic changes. Urban conditions are considered similar to changing global conditions. The concept study is based on Space Time Substitution method, utilizing its advantage saving time and resources compared l...

Riparian vegetation, which performs many key ecological functions, has been modified or lost at an alarming rate during the past century as a result of human activity. The aims of this study are (a) to investigate the effects of poplar plantations on plant diversity in riparian zones; and (b) to estimate the ecological implications of extending cover by poplar plantations. For this purpose, we ...
