Abstract:
... Ancient wood-pastures are facing a major decline in several European countries. These habitats are of great importance for biodiversity because of their special semi-natural character that increases landscape variability and connectivity. In this paper we examine the habitat preferences of the tree pipit Anthus trivialis in an ancient oak wood-pasture, the Breite Natural Reserve, central Romania, ...

Abstract:
... Habitats, disturbed severely at least once a year, are often dominated by annual plants, which avoid disturbance by means of a short life span and massive production of seeds. Contrary to perennials, they lack pools of reserve meristems on and storage carbon in below-ground organs necessary for vegetative regeneration after disturbance. However, some annuals are able to initiate a bud bank on the ...

Abstract:
... DNA photolyase is perhaps the most ancient and direct arsenal in curing the UV-induced dimers formed in the microbial genome. Out of two cofactors of the enzyme, catalytic and light harvesting, differences in the latter have provided basis for categorizing photolyases of prokaryotes as folate and deazaflavin types. In the present study, the homology modeling of DNA photolyase of Enterococcus faeca ...

Abstract:
... Secretion of insulin could be stimulated by several ways. Comparison of glucose- and swelling-induced mechanisms in pancreatic islets revealed the involvement of a novel signal transduction pathway with specific features of osmotically stimulated peptide hormone release including Ca2+ independence and resistance to noradrenalin (NA) inhibition. Cell swelling can be induced by hypotonicity or small ...

We isolated mitochondria from Saccharomyces cerevisiae and examined Fe(III) reduction induced by a respiratory substrate (NADH or succinate), using a Fe(II)-specific chelator (bathophenanthroline disulfonate). In the presence of either 50 μM NADH or ...

Abstract:
... A growing body of literature suggests that infanticide is common in a variety of animals. However, most reports are concerned with infanticide by males and these evidences are often indirect or questionable. Here we describe the first videotaped non-parental infanticide by a female common pochard (Aythya ferina) which killed one conspecific duckling. Our observation does not suggest that this atta ...
