Assessment of phosphorus associated with Fe and Al (hydr)oxides in sediments and soils
JAN, Jiří
2016 - anglický The established fractionation scheme of Psenner and Pucsko with consecutive BD and NaOH steps was shown to be ineffective in distinguishing between the stable crystalline (hydr)oxides and their more active amorphous and poorly crystalline forms. These forms highly vary in their ability to sorb P and thus in their ecological significance. Dissolution kinetics of the Fe and Al minerals were performed using both the BD and NaOH extraction solutions. The results were applied to modify the original fractionation scheme for better quantification of P associated with active Al and Fe (hydr)oxides, and better estimation of the amounts of these Fe and Al forms in soils and sediments.

Is genetic diversity congruent with morphological diversity across the distributional range of the Melampyrum subalpinum group (Orobanchaceae)?
CHLUMSKÝ, Jan
2016 - anglický Allozymes were used to assess the genetic structure of 27 populations of Melampyrum subalpinum group and an artificial pollination experiment was carried out to examine the possibility of autogamy. Genetic variation was generally congruent with the known morphological variation of the group. The results corresponded with the central-marginal concept. Allelic enrichment due to hybridization with M. nemorosum was observed in some Austrian populations. Czech and Slovak populations do not differ from Austrian populations. The high inbreeding coefficient and the pollination experiment do not contradict the possibility of autogamy.

Rapid turnover of the W chromosome in geographical populations of wild silkmoths, Samia cynthia ssp.
ŠÍCHOVÁ, Jindra
2016 - anglický Geographical subspecies of wild silkmoths, Samia cynthia ssp. (Lepidoptera: Saturniidae) exhibit a unique polymorphism in chromosome numbers, resulting from variations in the sex chromosome systems. Three different sex chromosome constitutions were identified: Z0/ZZ in S. c. ricini (2n=27/28), neo-Wneo-Z/neo-Zneo-Z in S. c. walkeri (2n=26/26), and neo-WZ1Z2/Z1Z1Z2Z2 in S. cynthia subsp. indet. (2n=25/26). It has been proposed, that the common ancestor of S. cynthia subspecies had a classical WZ/ZZ constitution with diploid chromosome number of 2n=28/28 and the neo-sex chromosomes in S. c. walkeri and S. cynthia subsp. indet. arose by repeated sex chromosome-autosome fusions. Our sampling effort enabled us to examine five populations of S. cynthia with an ancestral-like karyotype with the aim to verify a hypothesis about sex chromosome evolution in this species complex. Obtained results suggest that the curious WZ system of S. cynthia pryeri may represent an ancestral state of the Samia species complex. However, they do not exclude an alternative hypothesis of its derived origine.

Analyses based on cytochrome b sequences confirm the existence of two monophyletic lineages/species of Haemoproteus infecting Testudo tortoises.

Conservation value of post-mining headwaters: drainage channels at a lignite spoil heap harbour threatened stream dragonflies
TICHÁNEK, Filip
2016 - anglický V práci jsme se prozkoumaly společenstva vážek 52 sekcí (30m) odvodňovacích kanálů Radovesické výsypky. Pomocí zobecněných lineárních modelů a mnohorozměrných metod analýzy dat jsem identifikovaly klíčové faktory ovlivňující složení, diverzitu a ochranářskou hodnotu společenstev vážek na studovaném území. V práci pak navrhujeme řadu doporučení pro obnovu podobných post-těžebních území. In the work, we studied the biodiversity of dragonflies and damselflies (Odonata) at 53 sections (30 m) of an extraordinarily dense system of drainage ditches at a large lignite spoil heap in the Czech Republic. Using generalized linear models and canonical correspondence analyses we identified crucial factors affecting dragonfly communities and suggested implications for restoration ecology practise.
