Based on molecular studies, the small Chinese genus Petrocodon (two species and one variety) has been recently enlarged to include monotypic genera Calcareoboea, Paralagarosolen Tengia. It is shown here that (6-7) of Lagarosolen, Dolicholoma, a few Didymocarpus, number new have published (but not formally described) under Lagarosolen should be included in this genus. This raises size from five around 20 species. With respect floral diversity (corolla form, size, coloration; with exception...
The precision and reliability of quantitative nucleic acid analysis depends on the quality sample analyzed integrity acids. RNA is currently primarily assessed by ribosomal RNA, which far dominant species. extrapolation these results to mRNAs microRNAs, are structurally quite different, questionable. Here we show that some nucleolar mitochondrial RNAs, highly resistant naturally occurring post-mortem degradation, while mRNAs, although showing substantial internal variability, generally much...
Host specificity varies among parasite species. Some parasites are strictly host-specific, others show a for congeneric or non-congeneric phylogenetically related host species, whilst some non-specific (generalists). Two cyprinids, Cyprinus carpio and Carassius gibelio, plus their respective hybrids were investigated metazoan parasites. The aim of this study was to analyze whether interspecies hybridization affects specificity. different degrees within phylogenetic framework taken into...
With the introduction of first high-throughput qPCR instrument on market it became possible to perform thousands reactions in a single run compared previous hundreds. In reaction, only limited volumes highly concentrated cDNA or DNA samples can be added. This necessity solved by pre-amplification, which part experimental workflow. Here, we focused our attention limits specific target pre-amplification reaction and propose optimal, general setup for gene expression experiment using BioMark...
Bats are natural reservoirs of numerous coronaviruses, including the potential ancestor SARS-CoV-2. Knowledge concerning interaction between coronaviruses and bat cells is sparse. We investigated ability primary from
The article explores the construction and preservation of Holocaust memory in small Czech village Kosova Hora. study, based on focus group interviews, reveals how local is shaped by a unique combination activism, history, communal practices. highlights role Jewish couple who, rescuing restoring synagogue during Communist era, created central site for remembrance. This act catalyzed broader engagement, resulting collective effort to remember community that once thrived there. now serves not...
Morphometric and genetic variation were examined in parental Carassius auratus gibelio carassius individuals, their natural hybrids. Of meristic traits, only the number of gill rakers clearly distinguished hybrids (39·4 ± 1·4) from C. a. (48·3 0·7) (28·6 1·1). MtDNA sequences showed that descendants female . Microsatellite analysis confirmed presence variants typical
Abstract This article documents the addition of 268 microsatellite marker loci to M olecular E cology R esources D atabase. Loci were developed for following species: A lburnoides bipunctatus, C hamaerops humilis, hlidonias hybrida, yperus papyrus, F usarium graminearum, L oxigilla barbadensis, acrobrachium rosenbergii, O dontesthes bonariensis, P elteobagrus vachelli, osidonia oceanica, otamotrygon motoro, hamdia quelen, S arotherodon melanotheron heudelotii, ibiraea angustata, T akifugu...
Hybridization and polyploidization are important evolutionary processes whose impacts range from the alteration of gene expression phenotypic variation to triggering asexual reproduction. We investigated fishes Cobitis taenia-elongatoides hybrid complex, which allowed us disentangle direct effects both processes, due co-occurrence parental species with their diploid triploid hybrids. Employing morphological, ecological, RNAseq approaches, we molecular determinants polyploid forms. In...
Wild‐captured 16 diploid, five triploid and one tetraploid Prussian carp Carassius gibelio males produced motile haploid, aneuploid (1·5n) haploid to (> 2n) sperm, respectively, in similar concentration with the lowest percentage of live spermatozoa sperm for male (mean ± s . d 83·03 1·76%; P < 0·05) compared diploid (97·37 1·11% 96·70 1·45%; > 0·05).
The effect of water temperature and flow on the migration fish was observed using weekly inspections a fishpass lowland section River Elbe (Střekov, Czech Republic) from spring to fall 2003 2004. examined separately for immature (up 2 years old) adult also most abundant species (roach Rutilus rutilus, bleak Alburnus alburnus, chub Squalius cephalus, gudgeon Gobio gobio). More than 13 thousand 23 were recorded in during both years. highest levels occurrence spawning migrations adults...
The invasion success of gibel carp (Carassius gibelio) depends on demographic and competitive traits. major biological trait responsible for the invasiveness C. gibelio is mode reproduction. Apart from sexual reproduction, which typical in fish, a unique cyprinid species able to reproduce through asexual gynogenesis, also known as sperm-dependent parthenogenesis, observed all-female populations. Though forms co-exist widely natural habitats, gynogenetic form has capacity modulate range...
Leptospirosis is a bacterial zoonotic infection of worldwide occurrence. Bats, like other mammalian reservoirs, may be long-term carriers that maintain endemicity and shed viable leptospires in urine. Direct and/or indirect contact with these Leptospira shedders the main risk factor as regards public health concern. However, knowledge about bat leptospirosis Palearctic Region, Europe particular, poor. We collected urine from 176 specimens 11 species Czech Republic, Poland, Republic Armenia...
Especially in the temperate zone, female bats are exposed to increased energy demands during gestation. In addition, abiotic factors, such as ambient temperature and pathogen load, can significantly affect reproduction success. Bats considered natural reservoirs for a wide variety of pathogenic agents, have developed strong immune systems cope. Nevertheless, very little is known about influence these microorganisms on bat health most infections asymptomatic. this study, we monitored presence...
Gibel carp (Carassius gibelio) is a cyprinid fish that originated in eastern Eurasia and considered as invasive European freshwater ecosystems. The populations of gibel Europe are mostly composed asexually reproducing triploid females (i.e., by gynogenesis) sexually diploid males. Although some cases coexisting sexual asexual reproductive forms known vertebrates, the molecular mechanisms maintaining such coexistence still question. Both reproduction modes supposed to exhibit evolutionary...
