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 currently documented fauna of described species of myriapods in Canada includes 54 Chilopoda, 66 Diplopoda, 23 Pauropoda, and two Symphyla, representing increases of 24, 23, 23, and one species, respectively, since 1979. Of the 145 myriapod species currently documented, 40 species are not native to Canada. The myriapods have not been well documented with DNA barcodes and no barcodes are available for Pauropoda. It is conservatively estimated that at least 93 additional myriapods species will be discovered in Canada: Chilopoda (40), Diplopoda (29), Pauropoda (17), and Symphyla (seven). In general, there is a serious dearth of knowledge about myriapods in Canada, and systematics research and surveys continue to be needed to help document the diversity and distribution of these groups in the country.

Red Listing of Threatened species is recognized as the most objective approach for evaluating extinction risk of living organisms which can be applied at global or national scales. Invertebrates account for nearly 97% of all animals on the planet but are insufficiently represented in the IUCN Red Lists at both scales. To analyze the occurrence of species present in regional Red Lists, accounts of 48 different countries and regions all over the world were consulted and all data about myriapods (Myriapoda) ever assessed in Red Lists at any level assembled. Myriapod species assessments were found in eleven regional Red Lists; however, no overlap between the species included in the global IUCN Red List and the regional ones was established. This means that myriapod species considered threatened at regional level may not be eligible for international funding specific for protection of native threatened species (more than US$ 25 million were available in the last decade) as most financial instruments tend to support only threatened species included in the IUCN Red List. As the lack of financial resources may limit protection for species in risk of extinction, it is urgent to increase the possibilities of getting financial support for implementation of measures for their protection. A Red List of all Myriapoda species recorded in Red Lists at national or local (596) and global (210) scales totaling 806 species is presented. This list shows for the first time an overview of the current conservation status of Myriapoda species. Here, the urgent need of establishing a Myriapoda Specialist Group in the Species Survival Commission of IUCN is also stressed.
