Protection of owl species living on the territory of the Czech Republic in international, EU and national European law Abstract There are ten species of owls in the territory of the Czech Republic. The once widespread order of carnivorous birds has faced unprecedented pressures as result of landscape change and civilizational demands in recent decades, as a result of which their European populations are shrinking. For these reasons, a need has risen to protect owls at the level of individual national legal systems, at the level of EU legislation and in the sphere of international conventions. In the first part of this thesis, the biological specifications of owls as well as their ecological and agricultural importance are explained. The thesis also follows the legal mechanisms, the overall level of legal protection of owls and the application of standards for the protection of owls in international law, European Union law and nationals' law, all of which is reserved for the second part of the thesis. The international legal protection of owls is emphasized due to the large fluctuation of bird species across countries and continents. On the other hand, the law of the European Union, on the other hand, brings an unprecedentedly successful model of unification of national legal systems in the joint regulation...

Význam dravců (Accipitriformes, Falconiformes) a sov (Strigiformes) v agrocenózách a antropogenní faktory, které je ovlivňují.
Seligová, Renáta
The aim of the thesis is to assess the effect of biological protection and anthropogenic effects that influence the number of raptors and owls in agrocenoses. The importance of these predators as biological protection of crop-plants against rodents is on the rise in the past decades. There is also an effort to examine the relationship between raptors and their prey to understand the topic better. From 2015 to 2017, 8,693 mouse-eating raptors and owls have been accepted to animal rescues in the Czech Republic. Although, it is necessary to take into account that only about 1% of injured birds get to the rescues. Most of them die further from the place of injury or become a prey of other predators. The majority of birds had been accepted due to injury, mostly because of electric wire burns (30.63%), road hit (21.85%) or obstruction impact (9.33%). Injury by another animal, feather damage and gun wound were not a rarity either. 42.95% of accepted birds died – 18.49% of these had to be destroyed (especially if the cause of injury was electric burns or road hit). The extent of anthropogenic threat on raptors and owls was analysed based on the abovementioned data. The last part of the thesis deals with the effect of biological protection against common voles (Microtus arvalis). Two specimens – Falco tinnunculus and Buteo buteo – were assessed on an area of 100 km2 with the estimated 26 pairs of each species. Several factors had to be taken into account in the estimate. The population of Falco tinnunculus removed 52,767 common voles per year and the population of Buteo buteo removed 177,708 of common voles per year. The predatory pressure on the vole is estimated to 12.9%. Even thought the number should not be omitted, it would not be accurate to state whether biological protection functions or not. There are several variables that must be taken into account. The result of the estimate is based on middle population density of common vole, thus it would much lower in case of accession of population gradation. On the contrary, raptors and owls can accelerate the fall of the population after gradation culimation and maintain a longer interval before a new gradation.

Caring for the injured and otherwise handicapped Raptors (Falconiformes) and owls (Strigiformes) in rescue centers
SLAVÍKOVÁ, Kristýna
At least half of our raptors and owls are classified into three categories the list of specially protected animals. Electricity poles, traffic and landscape changes have led to the disappearance many individuals of raptors and owls in the wild. This work evaluates range and success of the return raptors and owls into the wild. All information about adopted raptors and owls were compiled by selected rescue station for animals ČSOP Vlašim. Rescue station records served as basis in the range of years 2009 - 2013. Most of Falconiformes were admitted individuals of Buteo buteo and Falco tinnunculus. Most common causes of admit into the rescue station were injuries by transport facilities or burns due to electric current. From Strigiformes were most admitted individuals Asio otus and Strix aluco. The most frequently been admitted youngs fell out of the nest . The total number of predators during the reported period were release back into the wild less than half of the accepted ones. The total number of admitted owls were release into the wild only a quarter of individuals.

Metody individuální identifikace u vybraných druhů ptáků
Stopka, Pavel
Studie obsahuje návrh spolupráce Ministerstva životního prostředí s referenční laboratoří a souhrnnou studii zaměřenou na zmapování konkrétních metod prokazování původu zvláště chráněných druhů sov a dravců včetně zvážení výhod a nevýhod jednotlivých metod. Součástí studie je seznam pracovišť vybavených technickým zázemím umožňujícím analýzu DNA výše zmíněnými metodami.

Hnízdní biologie sýce rousného v imisních oblastech Krušných Hor
Česká zemědělská univerzita v Praze, Praha ; Zárybnická, Markéta
Cílem studie bylo: a) vyhodnocení biotopů využívaných jedinci sýce rousného k hnízdění a k získávání potravy, a to mj. na základě dat získaných prostřednictvím telemetrie jedinců daného druhu (včetně odhadu velikosti domovského okrsku); b) vyhodnocení údajů o množství kořisti přinášené samcem za jednu noc na hnízdo v době inkubace a výchovy mláďat získaných prostřednictvím kamerových systémů umístěných v hnízdních budkách; c) vyhodnocení výše uvedených údajů ve vztahu k údajům o početních stavech populací drobných savců ve studovaném území získaných prostřednictvím odchytu do pastí během hnízdního období.
