Faktory ovlivňující výskyt vodních makrofyt v nádrži Lipno
KROLOVÁ, Monika
2013 - český This RNDr. thesis focuses on the species composition and cover in the littoral of the Lipno Reservoir in 2006. Aquatic macrophytes are an essential component of littoral communities in lakes. Their reasonable development positively affects biodiversity and stability of the aquatic ecosystems and water quality. The aim of this study was to characterise the development of littoral macrophytes in Lipno Reservoir, an artificial lake with seasonal water level fluctuation, and highlight controlling factors for macrophyte occurrence. The development of macrophytes was examined at 114 segments of the shoreline, each 50 m long, situated along the whole reservoir perimeter in regular 1km distances. The segments were surveyed for phytocenology, shore morphology, pedological characteristics of substrate, and anthropogenic impact. The survey identified 53 macrophyte species (24 hydrophilic terrestrial, 17 emergent,1 floating-leaved, 2 free-floating, 4 submersed, and 5 amphibious). The average vegetation cover of the examined segments was 14 %, with approximately one third of the segments without any macrophytes and another third with vegetation cover less than 10 %. Macrophytes occurred only in the uppermost eulittoral zone down to the level of 75 % probability of water surface exceedance. On the basis of a correlation analysis, the major factors affecting macrophyte occurrence in the littoral zone were shore morphology, light conditions in water and erosion effect of waves that together with water level fluctuation caused loss of fine particles from and degradation of the substrate in the littoral zone. Klíčová slova: littoral vegetation; littoral morphology; vegetation cover; erosion effect of waves; water level fluctuation; grain size distribution of substrate Plné texty jsou dostupné v digitálním repozitáři JČU.

Raman Microspectroscopy of Individual Algal Cells: Sensing Unsaturation of Storage Lipids in vivo
KOTAS, Petr
2013 - anglický We have demonstrated the potential of Raman microspectroscopy for the fast and spatially resolved characterization of the composition of selected intracellular regions in individual living cells of three algal species. In particular, we have focused on lipid storage bodies and quantified the degree of unsaturation of algal lipids (iodine value). To verify our results, we developed a method for extraction of storage lipids from highly resistant Trachidiscus minutus cells and determined the fatty acid composition using GC/MS. We have found Raman microspectroscopy to be a fast, versatile, and virtually non-invasive tool for evaluating the potential of different algal species for algal lipid engineering and industry.

Prevalence of Cryptosporidium spp., Enterocytozoon bieneusi, Encephalitozoon spp. and Giardia intestinalis in wild, semi-wild and captive orangutans (Pongo abelii and Pongo pygmaeus) on Sumatra and Borneo, Indonesia.
MYNÁŘOVÁ, Anna
2016 - anglický The prevalence and diversity of Cryptosporidium spp., microsporidia and Giardia intestinalis in orangutans (Pongo abelii and Pongo pygmaeus) at seven different sites on Sumatra and Kalimantan were described using molecular methods. Out of the 298 examined animals, 33 were positive for the tested parasites at least once during the study. Microsporidia(Encephalitozoon spp. and Enterocytozoon bieneusi) were detected in orangutans for the first time and molecular data were obtained on Cryptosporidium spp. and G. intestinalis in this host.

Species diversity of Plagiorchis Lühe, 1899 (Digenea: Plagiorchiidae) in lymnaeid snails from freshwater ecosystems in central Europe revealed by molecules and morphology
ROHÁČOVÁ, Jana
2014 - anglický Tato studie používá molekulární a morfologické přístupy pro identifikaci morfologicky podobných larválních stádií (cerkárií) druhů Plagiorchis (Digenea: Plagiorchiidae), kteří parazitují plže čeledi Lymnaeidae ve sladkovodních ekosystémech střední Evropy. Pět morfologicky homogenních a geneticky odlišných linií druhů Plagiorchis bylo identifikováno spojením molekulárních dat pro mitochondriální gen cox1 spolu s detailními morfologickými údaji. Fylogenetické a srovnávací sekvenční analýzy využívající částečné 28S rDNA a ITS1-5.8S-ITS2 sekvence umožnily molekulární identifikaci tří druhů (P. elegans, P. maculosus a P. koreanus) prostřednictvím shody sekvencí larválních stádií a dospělců těchto digenetických motolic. Součástí předkládané práce je klíč k identifikaci cerkárií rodu Plagiorchis parazitujících populace plovatkovitých plžů ve střední Evropě. This study applies molecular and morphological approaches addressing the identification of morphologically similar larval stages (cercariae) of Plagiorchis spp. (Digenea: Plagiorchiidae) parasitising lymnaeid snail populations in the freshwater ecosystems of central Europe. Five morphologically homogeneous and genetically distinct lineages of Plagiorchis spp. were identified via matching molecular data for the mitochondrial cox1 gene with detailed morphometric data. Phylogenetic and comparative sequence analyses using partial 28S rDNA and ITS1-5.8S-ITS2 sequences allowed molecular identification of three species (P. elegans, P. maculosus and P. koreanus) via matching sequences from larval and adult digenean stages. A key for the identification of the cercariae of Plagiorchis spp. parasitising lymnaeid populations in central Europe is provided.

Spatial heterogeneity and seasonal succession of phytoplankton along the longitudinal gradient in a eutrophic reservoir
RYCHTECKÝ, Pavel
2013 - anglický Spatial distribution and seasonal succesion of phytoplankton along the longitudinal axis of a eutrophic Římov reservoir (Czech Republic) was investigated from April to October 2007, at 1?2 week intervals. Phytoplankton spatial heterogeneity was the most apparent during the summer reflecting a pronounced gradient of environmental parameters from the river inflow to the dam. The riverine zone differed markedly from downstream parts of the reservoir, being dominated by functional groups D and J (large cryptophytes and colonial diatoms). While a dense cyanobacterial bloom (groups H1 and M) occurred in the transition zone, considerably lower biomass of desmids (Group N) was found at lacustrine zone at the same time. A sudden flood event considerably altered nutrient and light availability, and later even resulted in cyanobacterial dominance in the whole reservoir.
