    On potentials and relevance of the use of copulatory structures in anostracan taxonomy (1997)
    Springer
    Hydrobiologia 359 (1997), S. 83-92 
    Details
    ISSN: 1573-5117
    Keywords: Branchiopoda ; Anostraca ; genital morphology ; genus concept

    Topics: Biology
    Notes: Abstract This paper reviews and extends the knowledge of anostracan penile morphology and its taxonomic significance. Since Linder‘s pioneering classification(based partly on male genital characters), the morphology of both basal and distal penile parts has been applied repeatedly to reorganize or establish higher anostracan taxa, or to extend their diagnoses. In general, the configuration of both basal and distal penile structures follows a constant pattern in well-defined genera. Size and shape of processes and spinulation on the basal (in Linderiella and Chirocephalidae) and the distal parts (in Parartemia), however, may show inter-specific differences. Variability in penile structures in the current genus Brachinella indicates the need for a taxonomic revision of this genus. Similar intra-generic penis morphology may contribute to hybridizability of congeners and validate Dubois‘genus concept for use in anostracans.

    Supplement to "Checklist of the Anostraca" (1997)
    Springer
    Hydrobiologia 359 (1997), S. 243-245 
    Details
    ISSN: 1573-5117
    Keywords: Anostraca ; checklist
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Our 1995 "Checklist of the Anostraca" covered all species described through 31 December 1993 along with those described in the volume from the Second International Large Branchiopod Symposium (Hydrobiologia 298). This supplement includes new species (14) described through 31 December 1996, one change in rank and one new species discussed in this symposium volume, anew synonym, and correction of errors discovered in the original. We do not update new range extensions. With these additions and changes, we number the named anostracan fauna of the world at 273 species and six subspecies organized in 23 genera. The need for more study of anostracan zoogeography is again demonstrated by the fact that seven of the 16 species added to the checklist are know only from their type localities. Until we have more complete information on the distributions of the species, it will not be possible to make an accurate evaluation of the status of anostracan biodiversity.

    Anostracans in dark sections of Saudi Arabian caves (1997)
    Springer
    Hydrobiologia 359 (1997), S. 203-206 
    Details
    ISSN: 1573-5117
    Keywords: Anostraca ; cave ; Saudi Arabia
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Anostracans were found living in ephemeral pools in the dark sections of three caves on the As Summan Plateau in Saudi Arabia. Branchipus schaefferi Fischer, 1834 occurred alone in one while it cohabited with Streptocephalus torvicornisbucheti Daday, 1910 in a second cave; fairy shrimps were observed but not collected from the third. None of the specimens demonstrated any of the types of morphological changes typically associated with cave adapted species. This is likely due to continuing colonization of the pools during flooding events.
