Seedling Predation

Effects of floral herbivory (grazing flowers) by slugs on production and quality of seeds of herbaceous plants have been rarely quantified. We studied consequences of grazing by an invasive slug Arion lusitanicus (Mabille) for inflorescences of dandelion (Taraxacum officinale Weber ex Wiggers). In May 2008, a grassy site in Prague-Ruzyně (Czech Republic) was densely populated by dandelion inflorescences. Of the 40% of the flowers grazed by the slug, 70% died before seed dispersal and seed was eaten from 10% of the closed mature inflorescences. Viability of seeds from inflorescences that survived slug grazing was not affected. In addition to seedling predation, grazing of flowers may be an important source of dandelion mortality at sites where this slug is abundant.

Vegetative Season

AbstractDandelion (Taraxacum officinale) is an abundant Asteraceae species of grassland and vasteland stands. Through the vegetative season each plant produces a number of short-lived inflorescens. Final stage of inflorescence development is seed dispersal that lasts 2 days. Despite its ephemeral persistence, inflorescences at this period host abundant fauna. In 2005–2010 the inflorescences were collected in regular intervals in May–October, at Prague-Ruzyně and selected sites of western Czech Republic. Typical fauna consist of Heteroptera adults and larvae (34 species), phytophagans feeding on receptacle and seeds (mainly Miridae, Pentatomidae, Rhopalidae) and predators consuming thrips (Anthocoridae). The composition of Heteroptera fauna varies through the vegetative season, and its abundance decreases with increasing altitude of the locality. Other fauna are relics of species consuming seeds in the post-flowering phase of inflorescence maturation (mainly Thysanoptera) and occasional visitors with no trophic relationship to dandelion (Coleoptera, Diptera, Hymenoptera, Araneae). The reasons for association of phytophagous Heteroptera and dandelion may be preferences for seed consumption and chemicals present in plant tissues and possibly used for sequestration of aposematic substances.

The allowance introduces the lay and professional public project The mole in the network. This project aims at support the comprehensive care of children with oncological disease, their siblings and parents. The chief aim of the project is to create networks of organizations at the level of nonprofit organizations, educational and health organizations and universities that deal with improving the quality of life of children with oncological disease during and after treatment. It will be created a system of cooperation at the level of Endowment fund pediatric Oncology KRTEK (Czech Republic), Palacky University in Olomouc (Czech Republic) and the Regional youth council of Žilina (Slovak Republic). With the czech-slovak cooperation we want to create an unique system of exchangeable residential programs aimed at adapted physical activity where the children with oncological disease, their parents and siblings from the Czech and Slovak Republic will meet together and attend the programs under professional guidance.

The chapter presents the problem of quality of life modeling in the Czech Republic based on classification methods. It concerns a comparison of methodological approaches; in the first case the approach of the Institute of Sociology of the Academy of Sciences of the Czech Republic was used, the second case is concerning a project of the civic association Team Initiative for Local Sustainable Development. On the basis of real data sets from the institute and team initiative the authors synthesized and analyzed quality of life classification models. They used decision tree classification algorithms for generating transparent decision rules and compare the classification results of decision tree. The classifier models on the basis of C5.0, CHAID, C&RT and C5.0 boosting algorithms were proposed and analyzed. The designed classification model was created in Clementine.

 Genetic diversity was detected in 11 varieties of triticale registered in the Czech Republic by means of polymorphism of prolamin proteins using the PAGE ISTA method. The polymorphism of prolamin proteins allowed the differentiation of the individual triticale varieties in 2002 and 2003 harvests. On the basis of Dice’s calculations of coefficients of similarity we discovered, in parallel with the uniform genotypes, genotypes with sister prolamin spectrums with a different percentage of participation in the respective years. A uniform spectrum was detected in the following varieties: Disco, Kolor, Lamberto, Marko, Presto, Sekundo, Ticino and Tricolor; Kitaro and Modus were dimorphous varieties. In 2003 three sister prolamin lines appeared in the variety Gabo and in 2004 only two. In 2003 a 5% admixture of a foreign genotype was detected in the variety Marko. Typical of the unknown genotype was the gliadin block Gld 1B3, which is the marker of rye translocation T1BL.1RS, gene Sr31 with resistance to black rust, higher cold resistance and lower baking quality of the wheat. The prolamin proteins of triticale grain are suitable for the detection of the genetic diversity and for the assessment of varietal authenticity and purity in seed samples of triticale varieties registered in the Czech Republic.

Number Of Seeds

Following the entire process of frugivore seed dispersal, from intake of seeds to seed deposition, is a difficult task. One alternative is to monitor areas of heavy seed rain deposited by animals. We quantified the number of seeds deposited by hornbills and followed the fates of these seedlings for 3 y to evaluate the effectiveness of hornbill seed dispersal at nest trees, on the basis of seedling survival. For 14 mo, fallen fruits and seeds were collected in traps established around four nest trees of each of two hornbill species (Aceros undulatus and Anthracoceros albirostris) and the seedlings were monitored in adjacent quadrats. Seedfall and seedlings of species represented in hornbill diets occurred at significantly higher densities in the traps/quadrats in front of nest cavities than in other traps/quadrats. Fewer seedling species and individuals germinated under nest trees than expected from the composition of the seedfall. Our results suggest that the quality of hornbill seed dispersal might be poor at nest trees due to the highly concentrated seedfall, which results in high seed and seedling mortality. Although seed deposition at nest trees is a useful guide to hornbill diet during the breeding season, it is clearly not of benefit to the plants involved. However, the pattern and consequences of hornbill seed dispersal at nest sites is likely very different from that during the non-breeding season.
