Ranunculus L. with about 600 species is the largest genus in the Ranunculaceae. Problems in the taxonomy of the genus are due to high variability and polymorphism among different individuals and populations of certain species. Morphological characters of nectar scale have been considered as valuable taxonomical characters in some perennial species in some groups (Praemorsa, Grumosa, Rhizomatosa...

Protein and phenolic compound content antioxidant capacity were determined from honey bee collected unifloral pollen pellets Ranunculus, Brassica, Filipendula, Rubus, Vicia, Trifolium, Epilobium, Taraxacum species of boreal coniferous zone in Finland. The aim the study was to investigate relation between chemical composition botanical origin pellets. protein ranged 18.2 29.3%. One hundred twent...

Abstract A new Ancistrus species is described from Tapajós and Xingu river basins. It distinguished its congeners by the singular body color pattern, consisting of dark vermiculated stripes almost all over body, also combination features as a narrow head, large internostril distance, absence rows enlarged odontodes on lateral plates. In addition, that inhabit rio basin presence fully-developed ...

BACKGROUND The production of microbial lipids has attracted considerable interest during the past decade since they can be successfully used to produce biodiesel by catalyzed transesterification with short chain alcohols. Certain yeast species, including several psychrophilic isolates, are oleaginous and accumulate lipids from 20 to 70% of biomass under appropriate cultivation conditions. Among...

Leaf color in some individuals of Cistus creticus turns transiently to red during winter, while neighboring individuals occupying the same site remain green. We have examined whether anthocyanin accumulation can be associated with variations in photosynthetic and/or photoprotective characteristics between the two phenotypes, rendering the red phenotype more vulnerable to photoinhibition and, ac...

In the framework of study on taxonomy of the genus of Septoria in Iran, we studied herbarium specimen of R. muricatus (IRAN 8006F) collected during 1990 from Golestan province (N Iran). A Septoria species was observed on the specimen with following morphological features: leaf lesions, brown, amphigenous, extended through the entire leaf and equally visible on both sides. Conidiomata amphigeno...
