Vliv průběhu počasí a délky fenofází na výnos vybraných polních plodin
Piroltová, Zdenka
The thesis is dealing with phenophases of winter wheat and spring barley. It assesses influence of the sum of active temperatures and the sum of effective temperature on the length of period between commencement of early mil ripeness and hard dough ripeness. Monitoring undertaken at the fields around Cholina village between years was used as foundation for this thesis. Phenological monitoring as well as weather data fron weather station of Czech Hydrometeorological Institute in Luká was used for analysis. In this thesis, data about winter wheat yield and spring barley yield from station of Central Institute for Supervising and Testing in Agriculture in Věrovany werw also used. Analysis was carried out in during twenty yares of monitoring. Evaluation of data shows that earlier commencement of mentioned phenophase does not occur, but begin vary considerably.

The rate of development variability of carrion beetles (Coleoptera: Silphidae).
Ejemová, Magda ; Jakubec, Pavel (advisor) ; Novák, Martin (referee)
This Bachelors thesis is focused on ecology and rate of development of insects, with special focus on carrion beetles (Coleoptera: Silphidae), of the genus Thanatophilus. The process of the development is affected by both biotic and abiotic surroundings. My thesis is focused on the abiotic aspect.
Main influences on the rate of development in the abiotic surroundings have the temperature, moisture, photoperiod and the quality and amount of sustenance. Temperature is the most important of them all, as it influences the physiological processes inside of the insect's body. The relation between the temperature and rate of development can be described by temperature characteristics. Amongst the most important features are the lowest developmental threshold (T0) at which the development begins and the sum of effective temperatures (SET), which is stated in diurnal mean temperatures that are needed for reaching certain stage of development.
The relationship between rate of the development and temperature can be described by linear or nonlinear models. The easiest and most commonly used model for figuring out the lower developmental threshold is the linear one. The linear model is convenient for its mathematical simplicity, but only the nonlinear models can show us the of development temperatures beyond the linearity.
These models are used in many different fields, but mostly in forensic entomology or the agriculture.
This thesis also suggests the methodology for future study of the rate of development variability for necrophagous beetle. Thanatophilus rugosus between geographically separated populations and for calculation of its developmental constants (T0 and SET).

Rostlinolékařské aspekty zvýšeného zastoupení kukuřice v pilotním zemědělském podniku
Bureš, Stanislav
The aim of the thesis was to describe and sum up the risk of an increased occurrence of maize in a sowing plan at BUREŠ farm in Švábenice in Vyškov area. The sum of effective temperature (SET) was calculated for the period between 1st January 2014 and the first appearance of western corn rootworm (Diabrotica virgifera virgifera). The temperature was measured in 0,3 m, 2 m and in the effective height using HOBO sensors. The data from a multi-purpose station from Teranos ALA network located at the farm and from the nearest meteorological station in Ivanovice na Hané was processed. Then the SET was calculated for lower threshold temperature development 5 and 10 degrees. The figures were interpreted and can be used to predict the occurrence of the corn rootworm in next years.

Fenologie lesních dřevin ve smíšeném porostu na polesí Bílovice nad Svitavou
Dvořák, Vojtěch
The phenological research was inquired into the Sessile Oak (Querus petraea Matt. Liebl.) and European Larch (Larix decidua Mill.) on the explorative area of ŠLP ML Křtiny which belongs to the forest district of Bílovice nad Svitavou. These two trees were in the 35 years old mixed stand. On the monitored trees, there were compared the beginnings and the durations of the particular phenological stages in the connection with the weather conditions in the particular year. The temperature fluctuations for the phenological stages were specified by sum of effective air temperatures higher than 5 °C and 0 °C. There were compared the duration of the spring and autumn phenological stages on the Sessile Oak and European Larch. The gained results were compared with the statements of other authors in the Czech Republic and abroad. There were also done the comparison of the beginnings and durations of particular phenological stages of the trees with the datas of the long--standing observation ČHMÚ on the area of the same height above sea level in the Czech Republic.
