Formalizing morphologically cryptic biological entities: New insights from DNA taxonomy, hybridization, and biogeography in the leafy liverwort <i>Porella platyphylla</i> (Jungermanniopsida, Porellales)
No full textPremise of the study: Recognition and formalization of morphologically cryptic species is a major challenge to modern taxonomy. An extreme example in this regard is the Holarctic Porella platyphylla s.l. (P. platyphylla plus P. platyphylloidea). Earlier studies demonstrated the presence of three isozyme groups and two molecular lineages. The present investigation was carried out to elucidate the molecular diversity of P. platyphylla s.l. and the distribution of its main clades, and to evaluate evidence for the presence of one vs. several species. Methods: We obtained chloroplast (atpB-rbcL, trnL-trnF) and nuclear ribosomal (ITS) DNA sequences from 101 Porella accessions (P. platyphylla s.l., P. x baueri, P. cordaeana, P. bolanderi, plus outgroup species) to estimate the phylogeny using parsimony and likelihood analyses. To facilitate the adoption of Linnean nomenclature for molecular lineages, we chose a DNA voucher as epitype. Key results: Phylogenies derived from chloroplast vs. nuclear data were congruent except for P. platyphylla s.l., including a North American lineage that was placed sister to P. cordaeana in the chloroplast DNA phylogeny but sister to the Holarctic P. platyphylla s.str. in the nuclear DNA phylogeny. European and North American accessions of P. cordaeana and P. platyphylla form sister clades. Conclusions: The genetic structure of P. platyphylla s.l. reflects morphologically cryptic or near cryptic speciation into Holarctic P. platyphylla s.str. and North American P. platyphylloidea. The latter species is possibly an ancient hybrid resulting from crossings of P. cordaeana and P. platyphylla s.str. and comprises several distinct molecular entities

Sphagnum comprises a speciose clade of mosses that dominates many wetland ecosystems, especially in the boreal zone of the Northern Hemisphere (Shaw et al. 2003). In particular, Sphagnum is an important and conspicuous component in peatlands, which perform a significant global function in regulating the Earth's atmospheric chemistry as well as providing valuable economic commodities (Rochefort 2000). Sphagnum holds an interesting position amongst mosses, with Cox et al. (2004) indicating that Sphagnum and Takakia form a clade sister to all remaining mosses.Published as part of <i>Konrat, Matt Von, Shaw, A.

Morphologically cryptic biological species within the liverwort Frullania asagrayana.
No full textUNLABELLED: PREMISE OF THE STUDY: The Frullania tamarisci complex includes eight Holarctic liverwort species. One of these, F. asagrayana, is distributed broadly throughout eastern North America from Canada to the Gulf Coast. Preliminary genetic data suggested that the species includes two groups of populations. This study was designed to test whether the two groups are reproductively isolated biological species. • METHODS: Eighty-eight samples from across the range of F. asagrayana, plus 73 samples from one population, were genotyped for 13 microsatellite loci. Sequences for two plastid loci and nrITS were obtained from 13 accessions. Genetic data were analyzed using coalescent models and Bayesian inference. • KEY RESULTS: Frullania asagrayana is sequence-invariant at the two plastid loci and ITS2, but two clear groups were resolved by microsatellites. The two groups are largely reproductively isolated, but there is a low level of gene flow from the southern to the northern group. No gene flow was detected in the other direction. A local population was heterogeneous but displayed strong genetic structure. • CONCLUSIONS: The genetic structure of F. asagrayana in eastern North America reflects morphologically cryptic differentiation between reproductively isolated groups of populations, near-panmixis within groups, and clonal propagation at local scales. Reproductive isolation between groups that are invariant at the level of nucleotide sequences shows that caution must be exercised in making taxonomic and evolutionary inferences from reciprocal monophyly (or lack thereof) between putative species.Version of Recor
Formation of children's salue orientations of older pupilage
No full textThe purpose of the thesis of the author Blanka Gubánová titled Formation of Children's Value Orientations of Older Pupilage is to deal with values, value orientations and value systems which are formed in the process of the human development. There are many factors to be related to the adoption of individual's values which are the part of sociocultural environment where the individual lives. The relation between them is therefore the object of the discussion in the first part (chapter 1 - 5). The issue of the values, value orientations and value systems are discussed from different perspectives. In the sixth and following the seventh chapters we analysed the developmental periods to show the gradual human maturation, self-evaluation, moral development which is reflected in the formation of value systems and orientations. The special attention is paid to adolescents
Nature - the best gym for kids in kindergarten
No full textTITLE: Nature - the best gym for kids in kindergarten AUTHOR: Blanka Dymáčková DiS DEPARTMENT: Department in English language SUPERVISOR: Mgr. Věra Kuhnová ABSTRACT: The subject for this Bachelor Thesis is the movement of children in the nature in the context of preschool education. The main goal to achieve in the practical part is to introduce games and physical activities from the all-year program called Adventures of the owl, which was executed in the last year in the forest kindergarten of Tři údolí. It is based on the use of the physical activities and games in all aspects of The training program for preschool education during the seasons.
