Qualitative pollen analysis of honey from bees kept in Czech Republic
VALEŠKOVÁ, Denisa
Pollen analysis is the determination of a pollen grains in a honey sediment. The main goal of the thesis was to qualitatively assess a honey from the bees breed in different parts of the Czech republic and to evaluate, if there are any differences in bee grazing between a bees breed in the city and a bees breed in the countryside. Investigate, if a pollen is associated with the colony diseases and higher susceptibility to the pesticides from the field crop. It was found that the dominant plant taxon were canola and fruit trees. In the urban centers was high concentration of the pollen grains from a woody plants, which bees probably visit in local parks. Rural areas were miscellaneous species with high concentration of the herbaceous plants that are part of the meadows.

Pallynological Analysis of Pollen Collected by Honey Bee (Apis mellifera) in the Prague-West District
Štrachová, Markéta ; Říhová, Dagmar (advisor) ; Hanel, Lubomír (referee)
Title of the Thesis The Palynological Analysis of the Pollen Collected by Honey Bee (Apis mellifera) in the Prague-West Area Abstract This diploma thesis underlines the importance and significance of bee pasture. The first part of the thesis contains the presentation of the honey bee (Apis mellifera). It also describes the structure of the pollen grain, pollen as such, and its use regarding bee nutrition, the factors determining bee harvest of pollen, the means of its collecting and the use of bee pollen and bee bread. Furthermore, there are characteristics of pollen pasture in the time of early spring, spring, summer, late summer and autumn. The second part is dedicated to the palynological analysis of the area of Prague-West, Úhonice. The diploma thesis contains the evaluation of the food offer for the bees from the aforementioned location, and the summary of pollen-yielding plants blooming between 1 April 2017 and 27 June 2017. The sampling of pollen balls, which had taken place within this time span, provided the initial information about the nutrition of bees as well as the data regarding the diversity of plant species in the chosen location. In total, the samples contained 98 kinds of plants, out of which 31 were dominantly present above the limit of 6 percent. The longest lasting source of pollen was...

Attractive planting of species of potentially expanding bee pastures for bees
ŠEBESTA, Tomáš
This diploma thesis entitled "Attractiveness of Planting Species with a Potential to Extend Bee Forage for Bees" discusses pollen and nectar plants planted in the Brník municipality in the Central Bohemian Region. The thesis consists of two parts. The theoretical part describes honeybees, bee plants and their pollen- and nectar production ability as well as bee forage from early spring until late autumn so as to reflect the needs of pollinators as best as possible. The practical part uses pollen analysis to microscopically analyse the representation of pollen grains of plants in the honey produced by local bee colonies. Pollen analyses of honey from own bee colonies are compared with that from bee colonies belonging to neighbouring beekeepers.

Honey selected quality changes depending on the different ways of feeding of honeybee
HRADILOVÁ, Kristina
The goal of my thesis is to describe how external environmental factors influence beehives with regards to impacts on the quality of honey. The first part classifies various types of honeys and their qualitative characteristics in connection to their physical and chemical properties. The second part continues with description of bee pasture throughout the year and description of distinctive properties of certain monofloral honeys. Further, I am focusing on the issues of pesticide residue, medical substances and heavy metals in honey.

Evaluation of the attractiveness of individual plants and types of pollen for honey bees in depending on their action radius range in Mladá Boleslav area (Central Bohemia).
Kroupa, David ; Farkač, Jan (advisor) ; Vítězlav, Vítězlav (referee)
The aim of my bachelor thesis was to create a summary of pollen pasture of the European honey bee in the Mladá Boleslav area.
In theoretical part, I have put together basic information related to the European honey bee and pollen (bee colony, body structure, bee evolution, bee communication, pests and diseases, bee and plant relationship, harvesting and consumption of pollen, pollen load and bee products).
In the practical part, I have determined the pollen load's origin by analyzing pollen. This method was carried out with an illuminated binocular microscope. The plants are sorted into families. This data was then used in statistics, graphs and charts.
Altogether, It was collected 4 721 pollen loads between the years 2015 and 2016. I gathered 2 553 samples in 2015 and 2 168 samples in the following year. The biggest pollen pasture was offered by the Brassicaceae family in 2015 and by family Lamiaceae in 2016.

Beekeeping farms in the micro-region Holicko
Ropek, Milan ; Titěra, Dalibor (advisor) ; Hana, Hana (referee)
This Diploma Thesis is focused on obtaining data, how many bee colonies can be found in the micro-region Holicko. Then it wants to confirm or disprove the hypothesis, if the number of bee colonies is sufficient in this micro-region.
To meet this objective the analysis in this area was made. The list of bee colony territories was written in collaboration with ČSV, especially with the aid of ČSV ZO Holice. Maps of bee colonies in particular areas of the micro-region Holicko were made according to the data. There you can see flight circuit of bee colonies and their overlapping in relation with bee food sources.
The bees have really important role in the nature and an irreplaceable function for men. They provide known bee products and ensure lives of many plant species by pollinating. In the monitored area the number of bee colonies is sufficient but its allocation is not optimal. It means, that there are too many bee colonies in some areas and it can have a negative impact on bee nourishment and their state of health.

Effect of grazing diversity on bee colony health status
ŠEBESTA, Tomáš
The Bachelor thesis aims at establishing the impact that diversity of bee forage has on the state of health of the bee colony. Honeybees are important for the life on this planet. The first part of the thesis presents a description of honeybees and of what is natural for, and indispensable to, their life. It presents plants that offer high- or low-quality pollen and nectar in our climate conditions during the year according to the phenological calendar, and also discusses changes in our landscape in the course of history. The second part focuses on substances that may help bees to fight against diseases and pests.

Natural sources of apian pasture and biocide agents
SEDLÁKOVÁ, Lucie
In this bachelor´s work I am trying to emphasize importance of bee´s grazing. A bee is an inseparable and indispensable part of countryside. In the first part there is an outline of economical and ecological significance of "Apis mellifera". Further I deal with description and introduction of pollen and its importance in nutrition of bees, pollen wimples, honey-giving plants, nectar and nectar-giving plants and also honeydew and its producers. Then I write about indicators of quality of bee´s grazing. In the next chapters there is description of sources of bee´s grazing during all the year according to phenological calendary. The second part is dedicated to poisoning of bees and how it is possible to protect bees.

Important plants in terms of pollen for bee-keeping in the summer and late summer in the area of the protected landscape Šumava
PAŠKOVÁ, Dagmar
Objective of the work was to identify botanical origin of bee pollens collected from Protected Landscape area Šumava near the village of Volary and evaluate the importance of individual plant species in the diet of honey bees. The work also includes statistical analysis which examined how many subscriptions to a plant taxa occurred and what share has a certain plant taxon in the total pollen clutch. There were counted 18 different pollen taxa of bee pollens collected during summer and late summer of 2011. The work is complemented by photographs of selected pollen grains.
