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...

BACKGROUND AND AIMS Apomictic plants maintain functional pollen, and via pollination the genetic factors controlling apomixis can be potentially transferred to congeneric sexual populations. In contrast, the sexual individuals do not fertilize apomictic plants which produce seeds without fertilization of the egg cells. This unidirectional introgressive hybridization is expected finally to repla...

Water level regulation for purposes of hydropower production has caused notable changes in the littoral zones of regulated lakes in northern Finland. Marked geomorphological changes have taken place in the lakes with a raised water level. Lowering of the ice cover during the winter has also caused rapid changes in the littoral. Changes in the environmental conditions and aquatic macrophyte comm...
