Parasitation of the European marine gobies (Gobiidae, Perciformes) by metazoan parasites
Slámová, Tereza ; Vukićová, Jasna (advisor) ; Mašová, Šárka (referee)
Gobiidae (Teleostei, Perciformes) is one of the most species-rich families of teleost fishes, comprising over 1,700 species currently recognized. They inhabit marine waters worldwide, with the exception of the Arctic and Antarctic regions, but also brackish and freshwater habitats. Mostly, they live inconspicuously on the bottom. They are usually small-sized, so they are suitable intermediate hosts in the transfer of parasites to larger fishes, or to birds and mammals. The main metazoan groups of parasites of gobies are Myxozoa, Monogenea, Digenea, Cestoda, Nematoda, Acanthocephala and Crustacea. Their life cycles and the known impact of parasites on fish physiology, fitness, behaviour and mortality are described. Additional effects on goby hosts such as the effect on reproduction and the effect on a female mate choice are mentioned, as well. The immunity response of fish to parasitation is briefly discussed. Finally, some special cases like parasitism in brackish and eutrophicated waters, and a difference in parasitation of gobies in protected and unprotected areas are discussed. Published works about parasitation of European marine gobies are scattered and usually are focussed on a single parasite species or group. The effects of a parasite on a goby are rarely described. Only some parts of...

Review of knowledge on the Mediterranean marine gobies
Chalupecká, Katarína ; Vukićová, Jasna (advisor) ; Petrtýl, Miloslav (referee)
Gobies (Gobiidae, Perciformes) are small, inconspicuous fishes occupying marine, brackish and freshwater environments. They are very abundant group, with more than 1,700 species and around 260 genera currently recognised. Gobies have worldwide geographical distribution in coastal waters with exceptions of Arctic and Antarctic areas. More than half species occur in tropical seas. In the Mediterranean Sea, 61 species are known up to date, which inhabit four main types of habitats: benthic, cryptobenthic, hyperbenthic and nektonic. The European gobies were assigned to three distinct lineages. In all these lineages, north-east Atlantic and Mediterranean species are placed together, which evidences common evolution of the gobies from these two water masses. A variety of ecological and biological traits can be seen within each of the European goby lineage. The nectonic way of life evolved three times independently in the course of evolution. Although Gobiidae are the most specious fish family in the Mediterranean, there is still little information about most of the species. In some cases, the assumption on geographical distribution is based just on several findings. The life-span and reproduction is known for about one third of species. This work is a summarization of the published data about the gobies...

Phylogenetic relationships within the Gobius-lineage (Gobiidae)
Slámová, Tereza ; Vukićová, Jasna (advisor) ; Tougard, Christelle (referee)
Gobiidae is one of the largest families of teleost fishes with nearly 2000 species currently recognized. They have a worldwide distribution with exception of Arctic and Antarctic areas, inhabiting marine, brackish and freshwaters. Mostly, they are small-sized and live inconspicuously on the bottom. Their phylogeny has been studied only partially. In Europe, three independent lineages of gobies exist (Gobius-, Aphia- and Pomatoschistus-lineage), most of the species of these lineages are marine. In this work, I performed a multilocus study of the Gobius-lineage encompassing the majority of the species. Mitochondrial (cytochrome b and cytochrome c oxidase I) as well as nuclear (rhodopsin and recombination activating gene) markers were used. 480 individuals of 30 species were analyzed in the laboratory and sequences of further 25 - 32 species were downloaded from the Genbank and added to a dataset of each marker according to availability. Mitochondrial markers were more informative than the nuclear ones. The usefulness of cytochrome c oxidase I for studying phylogenetic relationships of gobies was compared with cytochrome b. Cytochrome c oxidase I showed to be useful for identification of the species, but has some limitations in resolving deeper phylogenetic relationships in gobies. Cytochrome b showed...
