Interbreeding between species (hybridization) typically produces unfit offspring. Reduced hybridization should therefore be favored by natural selection. However, this is difficult to accomplish because hybridization also sets the stage for genetic recombination to dissociate species-specific traits from the preferences for them. Here we show that this(More)
OBJECTIVES Intravenous thrombolysis (IVT) is considered an effective treatment for acute ischemic stroke (IS). However, not all treated patients may achieve good outcome. The aim was to evaluate whether the initial NIHSS and DWI infarct volume could be the predictors for good outcome after IVT. PATIENTS AND METHODS The set of 125 patients with consecutive(More)
Abstrakt: V oblasti odhadování IS/IT projektů bylo v uplynulých letech vyvinuto značné množství různorodých metod. Tyto metody by měly být používány s ohledem na několik faktorů. Volba a použití metody odhadu by měla zohlednit fázi projektu, ve které se odhadovatel nachází, a různorodé spektrum externích vlivů, jejichž složení a intenzita působení je velmi(More)
We examined migration routes and non-breeding sites of a poorly studied long-distance migrant, the Semi-collared Flycatcher Ficedula semitorquata, by tracking adult birds with geolocators from an eastern European breeding population across two subsequent years. All 11 birds migrated in a clockwise loop fashion where autumn migration routes lay east from the(More)
Geographic variation in phenotypes plays a key role in fundamental evolutionary processes such as local adaptation, population differentiation and speciation, but the selective forces behind it are rarely known. We found support for the hypothesis that geographic variation in plumage traits of the pied flycatcher Ficedula hypoleuca is explained by character(More)
