Komunikace mezi učitelem a žákem na 2. stupni ZŠ

Závěrečná práce se bude zabývat tématem komunikace mezi učitelem a žákem na druhém stupni základní školy. V teoretické části bude definován pojem komunikace, její zakotvení v školských dokumentech a specifika komunikace mezi učitelem a žákem. Praktická část bude založena na metodě dotazníkového šetření. Cílem bude zjistit pohledy respondentů ? učitelů ZŠ na kritické situace ve výuce, v třídnických hodinách a v průběhu přestávek, které jsou náročné z hlediska jejich vzájemné komunikace a stanovení jejích největších překážek

Synura echinulata (Synurales) - silica scale plasticity in natural populations influenced by environmental factors; accompanying scaled chrysophytes

The silica scale shape variation in Synura echinulata has been investigated only in laboratory conditions, so far. The aim of this thesis was to study scale shape variation in natural populations and to determine which environmental parameters influence the scale shape. The scale shape variation was investigated using landmark-based methods of geometric morphometrics. Scale shape changes related to environmental factors were analyzed using the two-block method PLS (Partial Least-Squares analysis) and adonis (R). The scale shape was mostly influenced by locality, pH and altitude. Shape distinguished populations of S. echinulata probably exist in different localities. The more distant localities are, the less similar are scales of S. echinulata in their shape. This scale shape variation is probably genetically determined, even thought all so far sequenced populations belong to the same species. High morphological disparity which was probably caused by anthropogenic pollution, was recorded in the locality Brdy. During sampling of the natural populations of Synura echinulata in the Czech Republic, several localities representing a significant reservoirs of species diversity, were found. Therefore, the thesis was extended and biodiversity research in the Czech Republic was added. A few samples were..
