Since about 1880 the scientific literature on Myriapoda has increased enormously. As this literature is widely dispersed in a huge number of scientific journals, we have started the German Myriapod Literature Project (GerMyLit) to gather literature published on Myriapoda. As a database standard we have adopted the field conventions of ...

The Diplopoda communities in 12 different forest habitats were studied in Bialowieza Primeval Forest, Poland. Material was collected in 1999 by pitfall trapping at 138 study sites. The epigeic communities of Diplopoda inhabiting the Bialowieza Forest consist of 10-14 species, depending on the type of forest. Glomeris connexa and Polydesmus ...
Voigtlander, Karin - - 2003
As part of a large-scale research program investigating endangered biotopes in the state of SaxonyAnhalt in eastern Germany, the centipede fauna of 50 sites, belonging to five types of xeric biotopes, was studied by pitfall trapping from 1995 to 1998 (each site for one year). The most abundant species was ...
Tufova, Jana - - 2003
The eastern part of the Czech Republic, Moravia, was effected by a disastrous flood in the summer of 1997. This flood washed away floodplain forest litter and most of epigeic soil invertebrates. Three adjoining floodplain forests were investigated to examine the effect of the flood on the population of Leptoiulus ...
Tuf, Ivan - - 2003
In July 1997 a disastrous summer flood affected extensive areas of Moravia in the Czech Republic. During the years 1998-2001 the development of communities of centipedes (Chilopoda) were studied in floodplain forests along the Morava River in the Litovelske Pomoravi Protected Landscape Area. Three floodplain forests of different ages (3, ...
Serra, Antoni - - 2003
This work was performed in an experimental plot in the Parc Natural de Sant Llorenc de Munt, Barcelona, Spain, in a sclerophilous forest of Mediterranean climate. This forest is made up mainly of Quercus ilex and Pinus halepensis trees and the most important bush species is Arbutus unedo. The litter ...
Grgic, Tanja - - 2003
The issue investigated was whether a distinction can be made between centipede communities from different development phases of an unevenly-aged beech forest stand. The influence of stand structure on centipede diversity, resulting from a particular forest management practice, was evaluated. Soil samples were taken three times during 2000 from a ...
Ruiz, A. - - 2003
The current work presents a study of the centipedes captured in three habitats of Toledo Province, Spain. These habitats correspond to a riverside, a well preserved green oak forest, and a rural field degraded by anthropogenic action. Sampling was performed using both direct capture and Berlese extraction from soil cores. ...
Redman, Guy - - 2003
The southern African Harpagophoridae comprises three genera: Zinophora (12 described and four undescribed species), Harpagophora (six described and one undescribed species) and Poratophilus (three species, including one unconfirmed species). Recent collecting in South Africa, and taxonomic revisions, have provided new insights facilitating a biogeographical study. The family is widely distributed ...
Mesibov, Robert - - 2003
Allopatric/parapatric distribution mosaics are apparently widespread among millipede genera, notably in Polydesmida. In this paper I discuss possible origins for these lineage mosaics and possible mechanisms for the persistence of their narrow parapatric zones, using mainly Tasmanian examples. Although it seems unlikely that lineage mosaics arise through rapid differentiation of ...
Kocourek, Pavel - - 2003
Twelve previously unrecorded species were discovered in the Czech Republic between 1970 and 2002. These species, belonging to the Mediterranean and Atlantic zoogeographic zone, have so far been found in synanthropic and semi-natural habitats in the Czech Republic. The occurrence of thermophilic species may correlate with the gradual warming of ...
Muller, C.H.G. - - 2003
Pore openings in different arrangements were observed between the ommatidia of the compound eyes of Scutigera coleoptrata (Scutigeromorpha) and Lithobius forficatus (Lithobiomorpha). Similar pores were not detectable between the ommatidia of either Scolopendromorpha or Craterostigmophora. Fine structural investigations revealed that the pores belong to epidermal exocrine glands. In order to ...
Hilken, Gero - - 2003
The present study describes a new head gland in Scutigera coleoptrata using light and electron microscopy. This multicellular complex gland is located at the dorsal side of the maxillary organ and is therefore called the 'maxillary organ gland'. This gland is composed of numerous secretory units, each of which is ...
Hilken, Gero - - 2003
The plasmatocytes of Scutigera coleoptrata were investigated by light and electron microscopy. Plasmatocytes exocytose fibrous structures that develop in their grana. The grana contain an electron-dense area in their centre, from which the fibrous material detaches. The grana transform themselves to vacuoles. The tubules may be released from the vacuoles ...
Ernst, Alfred - - 2003
Scanning and transmission electron microscopic investigations of the maxillipedes of adult centipedes and the first anamorphic larval stage of Lithobiomorpha show the presence of sensilla coeloconica on the surface of the poison claw. In maxillipedes of larval stages only a single type of sensillum is present. In the adult centipedes ...
Koch, Markus - - 2003
Current support for myriapod monophyly is revised based on a comparative study of the head morphology in Tetramerocerata (Pauropoda) and Pselaphognatha (Diplopoda). New data on the cephalic endoskeleton permit a reconstruction of the common pattern of the myriapod 'tentorium'. Polyxenus lagurus (Pselaphognatha) shows no principle difference to the original state ...
Edgecombe, Gregory - - 2003
Increasing evidence, in particular from gene expression data, indicates that mandibles throughout the Mandibulata are gnathobasic and that myriapod and hexapod mandibles do not represent 'whole limbs'. These observations do not necessarily imply that the gnathal edges of the mandibles are also homologous, though this homology finds some support from ...
Pripnow, Birgit - - 2003
This study was undertaken in order to obtain more data on the life history of Onychophora under laboratory conditions, and to help distinguish selected morphs of the 'Peripatoides novaezealandiae-complex'.
Duy-Jacquemin, M. - - 2003
The subclass Penicillata Latreille, 1829 (= Pselaphognatha Latzel, 1884), sister-group of the Chilognatha (Class Diplopoda), comprises a single order (Polyxenida Lucas, 1840; nomen translatum Chamberlin & Hoffman, 1958) and four families including tiny, hairy, arthropods (up to 7 mm long) characterised by a soft integument and the presence of numerous ...
Duy-Jacquemin, Monique - - 2003
Three genera of Penicillata, belonging to the family Polyxenidae, appear to show the sensilla on their gnathochilarial palps apically pseudoarticulated. These are Macroxenus Brolemann, 1917 (the type-species: Polyxenus rubromarginatus Lucas, 1846, from Algeria), Macroxenodes Silvestri, 1948 (the type-species: Polyxenus meinerti Silvestri, 1898, from Venezuela), and Chilexenus Silvestri, 1948 (the type-species: ...
Lewis, J.G.E. - - 2003
Difficulties encountered in achieving correct identifications of scolopendromorphs are detailed, and the need for work on variation is stressed. The causes of this variation are examined with particular reference to scolopendrids and Cryptops. Many of the characters used in specific determination cannot be explained in terms of their function, and ...
