Abstrakt: Bakalářská práce pojednává o diploidních počtech chromozomů, jejich morfologii a chromozomovém mechanismu určení pohlaví u čtyřech tříd podkmene Myriapoda. Pozornost je zároveň věnována vzájemným fylogenetickým vztahům v rámci podkmene. Přehled literatury ukazuje míru prozkoumanosti cytogenetických charakteristik u jednotlivých tříd, která je zejména ve třídách Pauropoda a Symphyla stále velmi nízká a v rámci třídy Diplopoda je stále ještě velké množství řádů, kde nám tyto informace zcela chybí. Cytogenetické analýzy odhalily celkové rozpětí počtu chromozomů pro: Pauropoda 2n = 12 – 27, Symphyla 2n = 11 – 18, Chilopoda 2n = 14 – 54 a Diplopoda 2n = 8 – 30. V rámci všech čtyř tříd se vyskytují jak morfologicky nediferencované pohlavní chromozomy, tak systémy typu XX/XY a XX/X0. Navíc je u řádu Spirostreptida uváděný i systém X1X1X2X2/X1X20. Pouze u malého množství druhů z řádů Glomerida, Calipodida, Julida, Spirostreptida a Lithobiomorpha a čeledi Scutigerellidae se podařilo identifikovat výskyt NORů. V práci se také podařilo identifikovat některé neshody mezi údaji různých prací, kdy se ukazuje, že zejména některé starší studie byly postaveny na špatném pozorování chromozomů v karyotypu.

Karyotype variability of Myriapoda

Abstract: The bachelor thesis deals with diploid numbers of chromosomes, their morphology and chromosome mechanism of sex determination in four classes of the subphylum Myriapoda. Attention is also paid to mutual phylogenetic relationships within the subphylum. A review of the literature shows the degree of examination of cytogenetic characteristics in individual classes, which is still very low, especially in the classes Pauropoda and Symphyla, and within the class Diplopoda there are still a large number of orders where we completely lack this information. Cytogenetic analyzes revealed a total range of chromosome numbers for: Pauropoda 2n = 12 - 27, Symphyla 2n = 11 - 18, Chilopoda 2n = 14 - 54 and Diplopoda 2n = 8 - 30. Within all four classes, there are both morphologically undifferentiated sex chromosomes and XX/XY and XX/X0 systems. In addition, the X1X1X2X2/X1X20 system is mentioned for the order Spirostreptida. Only a small number of species from the orders Glomerida, Calipodida, Julida, Spirostreptida, Lithobiomorpha and from family Scutigerellidae were able to identify the occurrence of NORs. The work also managed to identify some discrepancies between the data of different works, which shows that especially some older studies were based on poor observation of chromosomes in the karyotype.

The shallow underground of rock debris is a unique animal refuge. Nevertheless, the research of this habitat lags far behind the study of caves and soil, due to technical and time-consuming demands. Data on Myriapoda in scree habitat from eleven localities in seven different geomorphological units of the Czech and Slovak Republics were processed. Based on previous studies, as well as knowledge of cave and soil fauna, it was hypothesised that the occurrence of a varied and peculiar fauna would show a pattern of depth distribution with variations due to local specificities. From 2005–2016 (at least one year on each site), macrofauna was collected via sets of three long-term exposed subterranean traps consisting of 110 cm long perforated tube, with ten cups located in a gradient at 5–95 cm below the soil surface. In total, 14 symphylans (not identified to species level), 271 centipedes (23 spp.) and 572 millipedes (32 spp.) were sampled. The overall depth distribution of centipedes and millipedes appeared to have relatively similar pattern, with both groups being found at all depth levels. Nevertheless, this pattern depends on locations. The depth distribution trend lines are mostly in the form of an asymmetric ‘U’, with decreased abundance until the middle of the gradient, followed by increase in the deepest levels. Epigeic species were sporadically distributed along the whole depth gradient, but concentrated at the soil surface, while some subterranean species, such as the centipede Lithobius lucifugus and the millipedes Geoglomeris subterranea, Cibiniulus slovacus and Archiboreoiulus pallidus, were recorded in the deepest parts of the gradient. This characterises the debris community as a mixture of soil and subterranean species with an absence of species exclusively found in caves. The use of different fixation methods in traps had a significant and selective impact on samples; millipedes were either attracted by ethylene glycol or repelled by formaldehyde. Centipedes were also captured more frequently in ethylene glycol; however, the species composition varied in each of the fixatives. Depth distribution of myriapods was similar in both fixative solutions. Traps with these fixatives could be recommended for similar ecological studies.

The diplopod fauna of Georgia, Transcaucasia, is very rich given the country’s relatively small territory; it presently comprises 103 species from 44 genera, 12 families, and 7 orders. Most of the Diplopoda known from Georgia (86 species, or 83%) demonstrate Caucasian distribution patterns, 36 and 46 species, as well as 8 and 9 genera being endemic or subendemic to the country, respectively. A single Holarctic family, Anthroleucosomatidae (order Chordeumatida), contains 44 Caucasian species and 20 genera, of which 27 species and 14 genera are endemic or subendemic to Georgia. Likewise, all species from the orders Polyzoniida, Siphonocryptida, Glomerida and Chordeumatida, as well as most species of Julida and Polydesmida are native, also endemic or subendemic to the Caucasus, but the genera and families they represent are widely distributed at least across the Euro-Mediterranean Realm. Most of the presumed troglobionts in the Caucasus appear to be confined to western Georgia’s karst caves (14 species, 5 genera). Within Georgia, the fauna of the western part (= Colchis) is particularly rich and diverse, while that of the central and eastern parts of the country grows increasingly depauperate inland following the gradual climatic aridisation from west (Black Sea coast) to east (Armenia and Azerbaijan). The vertical distribution of the Diplopoda in Georgia, as well as the Caucasus generally, shows the bulk of the fauna restricted to forested lowland to mountain biomes or their remnants. Only very few Chordeumatida and Julus species seem to occur solely in the subalpine to alpine environments and thus may provisionally be considered as high-montane elements. Ongoing and future research on the millipedes of the Caucasus, especially in cave and montane environments, will undoubtedly allow for many more novelties and details of the diversity and distribution of Georgia’s Diplopoda to be revealed or refined.
