Utilization of Biology Olympiad in schools and implementation of selected tasks into highschool teaching.
Dvořáková, Darina ; Janštová, Vanda (advisor) ; Drda Morávková, Alena (referee)
This thesis deals with the Biology Olympiad and remaking of selected tasks of region round. The remaked tasks can be used in highschool education. The thesis includes theoretical and practical part. The theoretical part provides general information about the Biology Olympiad (BiO), charts the achievements of Czech students in International Biology Olympiad (IBO), includes literary review of selected topics. The practical part encompass four remaked tasks of different topics: Eucaryotic cell as a mosaic, Water in life of animals, Animals' areas and their distribution, History of the flora in Czech Republic. The tasks are processed in the form of worksheets. The worksheets were tested at schools. Knowledge of students was tested by using of created pretests and posttests. The practical part also presents the result of research based on a questionnaire survey focused on the involvement of school in BiO and teachers' opinions on these topics.

History of vegetational development in the Cheb basin from sedimentary record of the SOOS National Nature Reserve
Suda, Tomáš ; Kuneš, Petr (advisor) ; Bešta, Tomáš (referee)
Vegetation development in the Cheb basin ( W Czech Republic) recorded in the sediments of the SOOS ational ature Reserve This thesis focuses on palaeoecological research of quaternary sediments in the Soos National Nature Reserve (Cheb basin, NW Czech Republic). Quaternary history of this locality is poorly known, despite it is a valuable and protected area with high natural qualities. The Soos basin is also known for its unique geological record, which is expected to cover information on landscape dynamics at least during the Holocene. A lake existed in the Soos basin enabling accumulation of diatomite and peat sediments of a broad palaeoecological potential. Records were analysed with method of pollen analysis and were dated using 14C. The results of this study bring information about vegetation development in the area of Cheb basin as well as development of lake ecosystem. It also gives a new insight on lake's origin and its age. The accumulation of peat sediments started in the Preboreal period and was continuous at least until the Atlantic following with a hiatus, therefore further detection of vegetation development is impossible. The beginning of diatomite accumulation, as well as the existence of the lake goes back to the Bølling interstadial, according to radiocarbon dating. However, this...

The importance of production and quality of pollen in the summer and late summer for the bee colonies (case studies from around of the village Volary - CHKO Šumava)
PETROVÁ, Jana
Objective of the work was to identify with using pollen analysis botanical origin of bee-colected pollens collected from beehive station Lískovec near the town Volary in the Protected Landscape Area of Šumava. Bee-collected pollens were collected once a week from one honey bee colony with using of a pollen trap. The time of collection was summer and late summer period from 22 June to 11 September 2010. Bee-collected pollens were dried, categorized by color, weighed and observed using the microscope. Pollen grains were determined by the number and type of apertures, shape, sculpture and size. Size of pollen grains was measured on at least 50 pollen grains of one type. In each microscopic slide were counted at least 500 pollen grains. The proportion of plant species in the sample was expressed as a percentage and the importace of plant species was evaluated in the diet of honey bees in the area of interest. Selected samples of bee-collected pollens from beehive station Lískovec and also from beehive station Dobčice were investigated for protein content and amino acid composition. Pollen belonging to Polemonium coeruleum, Trifolium pratense and Trifolium repens was evaluated as an important source of protein and amino acids for honey bees. The concentration of essential amino acids expressed as percentages of total amount of amino acids did not differ significantly between samples of bee-collected pollen. Another objective of the work was to compare the results from the area of interest with the results processed in the similar study from beehive station Dobčice in the northern area of the landscape Blanský les. The work also includes statistical evaluation of dominance, frequency, Shannon-Wiener index of diversity and variability between samples and species. The work is complemented by photographs of selected pollen grains.

Antrophic influenced sediments of region Netolicko
TRÁVNÍKOVÁ, Kristýna
This study summarizes the results of geoarchaeological and palaeological research in the Netolice region and presents the results of the field prospection, intensive sampling research, pollen analysis and chronological determination. The study was conducted in basis of an archaeological and palynological literature related to the landscape and central location in Netolice region. Samples from open areas around Netolice were prepared by chemical analysis and further methods were used radiocarbon (14C) dating and spherodial carbonaceous particles (SCP) analysis. The results of the study were set in the context of the historical landscape.

Important plants in terms of pollen for bee-keeping in the spring and early summer in the area of the protected landscape Šumava
ŠEMRO, Martin
Objective of the work was to identify with using pollen analysis botanical origin of bee pollens. Pollen analysis consisted in the distribution of samples to individual sub-samples . Samples were weighed and a part of them was dissolved in a solution of glycerin and water. Dissolved samples were viewed under a microscope. Pollen was removed by the beekeeper Mgr .Milan Trhlín with using a device called pollen catcher. The samples were collected in the year 2011 in the spring and early summer period from beehive location on the hill Lískovec, of the protected landscape Šumava 1,8 km west of city Volary, at a time of 25. march to 24. june. Another objective of the work was with using phytocenology study, in the distance 1,5 km from the beehive habitat, evaluate the structure of plant association from the point of nutrition honeybees. The work also includes evaluation preference bees for individual plant species. There were detected, that bees prefer the plants that provide the best digest pollen and the plants which grows up to 1,5 km from beehive habitat. There were distinguised 32 types of pollen grains.

Important plants in terms of pollen for bee-keeping in the summer and late summer aspect in the northern area of the landscape Blanský les
PETROVÁ, Jana
Objective of the work was to identify botanical origin of bee pollens collected from the northern territory of Protected Landscape Area Blanský les by pollen analysis and assess the importance of individual plant species in the diet of honey bee in the range up to 2 km from the beehive. The work also includes statistical analysis, which examined how rich is the preference of bees in the collection of bee pollens, as well as the occuring of plant taxa in the proportion of samples and what is the similarity of sampling and individual plant taxa in terms of preference of bees. There were counted 23 766 different pollen types and plant taxa of bee pollens collected during summer and late summer between 2010 and 2011. The work is complemented by photographs of selected pollen grains.
