The European Kestrel Falco tinnunculus (L.) is commonly observed in urban-industrial environment. Colonization of cites by the species was shown to be interlinked with changes in its ecology and breeding biology. Such adaptations can lead to isolation of urban populations from rural birds. In this paper we investigated genetic differentiation between birds from centre of Warsaw (Centre Group), suburban...
Cuticle visualized by auramine O fluorescence on developing Arabidopsis thaliana embryos was investigated. Localization of the cuticle was studied on embryos of the zygotic wild Ler ecotype and nine lines of embryonic mutant: CS 2330, CS 3009, CS 3016, CS 3023, CS3025, CS 6330, CS 6340, CS 6343 and CS 6346. In Arabidopsis Ler ecotype embryogenesis, a fluorescing cuticle layer appears on the globular...
