Visual Enhancement of Ultrasound Images

Ultrazvuk je velmi častou a oblíbenou metodou lékařského vyšetření. Interpretace obrazu získaného při tomto vyšetření je ovšem netriviální a vyžaduje velkou zkušenost. Tato práce se zabývá technikami vylepšení obrazu z ultrazvuku a tedy usnadněním diagnozy. Představuje základní metody zpracování obrazu vhodné na tento typ úloh a představuje také několik pokročilých postupů. Je zde ukázán návrh aplikace, která tyto postupy spojuje a vytváří tak nástroj pro zjednodušení vizuální diagnostiky.Ultrasound imaging is widely used in medical examination. However, the interpretation of images is not trivial and requires much experience. In this thesis, various techniques for enhancement of visual quality of ultrasound images are presented. Several basic and advanced methods that may simplify the visual diagnosis are described. Finally, an interactive application is designed and implemented for simple usage of presented methods.

Taxonomic problems in the subgenus Meloehelea Wirth of the genus Atrichopogon Kieffer (Diptera: Ceratopogonidae) inferred from both morphological and molecular characters

The classification of Meloehelea (Ceratopogonidae) species is based on morphological characters. The taxonomic revision of generally well-known species recovered interesting facts on possible geographic intraspecific variability or on the presence of an additional valid species. In this study, 5 European species and 2 species from the U.S.A. and Canada have been compared based on their morphological characters. Subsequently, the 16S rDNA sequences analyses of well known European species have been performed to confirm the characters mentioned in the determination key ofthis subgenus. Although, this study was limited by the number of examined non-European specimens, it provides some interesting facts on the possible morphological variability of well-known species and also an initial phylogenetic backbone for the progressive reconstruction of infrageneric relationships within the genus Atrichopogon

New host and country records for European Tachinidae (Diptera)

The paper presents host records for 17 species of Tachinidae (of subfamilies Exoristinae and Tachininae) from the Czech Republic, Slovakia, Austria, Croatia, Macedonia, Italy, Spain, Portugal, and Bulgaria. New parasitoid-host couples are Exorista larvarum — Melanchra pisi; Exorista segregata — Catocala nymphaea; Sturmia bella — Hadena compta; Spallanzania multisetosa — Cycnia sordida (first host record); Tachina praeceps — Cucullia bubaceki; and Bithia modesta — Bembecia megillaeformis. New country records of tachinid species Rhacodinella apicata from the Czech Republic, Masicera pavoniae from Macedonia and Bithia demotica from Portugal are presented

Taxonomic approach to the tachinid flies Dinera carinifrons (Fallén) (Diptera: Tachinidae) and Dinera fuscata Zhang and Shima using molecular and morphometric data

Molecular phylogenetic and traditional morphometric methods were applied to examine six Palaearctic taxa of the taxonomically difficult tachinid fly genus Dinera Robineau-Desvoidy (Diptera: Tachinidae), with particular reference to D. carinifrons (Fallén) and D. fuscata Zhang and Shima. Results of a phylogenetic analysis based on the mitochondrial markers 12S and 16S rDNA and multivariate statistical analyses of 19 morphometric characters were used to delimit both species. A lectotype was designated for D. carinifrons to stabilize the nomenclature in the group. Dinera carinifrons has a transpalaearctic distribution and is present in Central Europe, especially in high altitudes of the Alps. It differs from the similar and closely related D. fuscata in that it has a slightly larger body size, a dense greyish microtrichosity on the body, and different head proportions. Dinera fuscata, as delimited here, is widespread in the Palaearctic region, including Europe. Slight differences in both molecular and morphometric characters were found between western (Europe and Iran) and eastern (China and Japan) populations of D. fuscata, which are interpreted as an intraspecific variation. Differential diagnosis between D. carinifrons and D. fuscata is provided in the form of a revised portion of the determination key to the Palaearctic Dinera by Zhang and Shima (2006).

Annotated host catalogue for the Tachinidae (Diptera) of the Czech Republic

An annotated host catalogue is given for the Tachinidae of the Czech Republic. It comprises 149 of 476 tachinid species which are currently known from this country (included the two new records cited below). 195 hosts are listed. The first host records of Tachinidae date back to the second half of the 19th century. The bibliography for the host records consists of 116 papers of 55 researchers. Several records of hitherto unpublished material are included. Phryxe setifacies and Anthomyiopsis plagioderae are first records for the Czech Republic

Identification and taxonomy of the West Palaearctic species of Tachina Meigen (Diptera: Tachinidae) based on male terminalia and molecular analyses

The male postabdominal structures of the West Palaearctic species of the genus Tachina are described. A new identification key is given. Characters are illustrated by original pen drawings and deep focus micrographs, some of them for the first time. The results are documented by molecular analyses (based on CO°I, Cyt°b, 12S, and 16S rDNA). This approach solves old taxonomical discrepancies, which resulted in these conclusions: 1) the taxonomic concept ofthe genus was evaluated; 2) the position ofthe present subgenus Tachina s.str. seems to be untenable: T. grossa (Linnaeus, 1758) could be categorized inside existing subgenus Tachina s.str. and a new subgenus could be created for T. magna (Giglio- Tos, 1890); 3) an expected new species from subgenus Eudoromyia was confirmed; 4) T. nigrohirta (Stein, 1924) having been resurrected from synonymy was confirmed as a valid species; 5) some differences between central European and Japanese specimens of T. nupta (Rondani, 1859) were found

Abstract Fauna Europaea provides a public web-service with an index of scientific names (including important synonyms) of all extant multicellular European terrestrial and freshwater animals and their geographical distribution at the level of countries and major islands (east of the Urals and excluding the Caucasus region). The Fauna Europaea project comprises about 230,000 taxonomic names, including 130,000 accepted species and 14,000 accepted subspecies, which is much more than the originally projected number of 100,000 species. Fauna Europaea represents a huge effort by more than 400 contributing taxonomic specialists throughout Europe and is a unique (standard) reference suitable for many user communities in science, government, industry, nature conservation and education. The Diptera-Brachycera is one of the 58 Fauna Europaea major taxonomic groups, and data have been compiled by a network of 55 specialists. Within the two-winged insects (Diptera), the Brachycera constitute a monophyletic group, which is generally given rank of suborder. The Brachycera may be classified into the probably paraphyletic 'lower brachyceran grade' and the monophyletic Eremoneura. The latter contains the Empidoidea, the Apystomyioidea with a single Nearctic species, and the Cyclorrhapha, which in turn is divided into the paraphyletic 'aschizan grade' and the monophyletic Schizophora. The latter is traditionally divided into the paraphyletic 'acalyptrate grade' and the monophyletic Calyptratae. Our knowledge of the European fauna of Diptera-Brachycera varies tremendously among families, from the reasonably well known hoverflies (Syrphidae) to the extremely poorly known scuttle flies (Phoridae). There has been a steady growth in our knowledge of European Diptera for the last two centuries, with no apparent slow down, but there is a shift towards a larger fraction of the new species being found among the families of the nematoceran grade (lower Diptera), which due to a larger number of small-sized species may be considered as taxonomically more challenging. Most of Europe is highly industrialised and has a high human population density, and the more fertile habitats are extensively cultivated. This has undoubtedly increased the extinction risk for numerous species of brachyceran flies, yet with the recent re-discovery of Thyreophora cynophila (Panzer), there are no known cases of extinction at a European level. However, few national Red Lists have extensive information on Diptera. For the Diptera-Brachycera, data from 96 families containing 11,751 species are included in this paper
