Systematics, phylogeny and faunistics of crustaceans
Studies, including revisions and descriptions of new species, of the genera of the isopod family Sphaeromatidae have been continued. The long term aims of the study are to identify the phylogenetically informative characters for all genera of the family, to develop a data matrix for cladistic analyses, and to place the genera into a phylogenetically based classification, which can then be related to the evolution and biogeography of the family (N.L. Bruce). Taxonomic studies on sphaeromatids have been continued (N.L. Bruce, with D.M. Holdich, University of Nottingham, and R. Wetzer, University of Charleston).
A revision of the family Aegidae, which are ectoparasitic on fish, has been initiated, beginning with papers on the genera Xenuraega*, Syscenus* and Aega. (N.L. Bruce)
A large-scale phylogenetic and biogeographic revision of the genera of the isopod family Cirolanidae comprising more than 400 species has been initiated (N.L. Bruce, with R.C. Brusca, University of Charleston). A revision of the genus Cirolana has been initiated (N.L. Bruce).
The chapter on marine isopods for the popular book "Field Guide to the Sea Shores of East Africa" has been prepared (N.L. Bruce).
Description of a new species of Booralana has been initiated (N.L. Bruce, J. Olesen).
A phylogenetic analysis of six of the eight orders of the Branchiopoda has been almost completed. A comparative study of the phylogenetic significance of the so-called dorsal organ of the family Chydoridae (Cladocera) has been carried out. A study of the morphology and phylogeny of smaller crustaceans (Mystacocarida, Leptostraca, Remipedia, and Branchiopoda) has been initiated; it comprises a description of the larval development of Derocheilocaris remanei (Mystacocarida) and a comparative study of the larval development of various branchiopods representing most of the systematic groups. A new species of Nebalia (Leptostraca) is being described, and the phylogeny of the leptostracan genera is being analysed (J. Olesen, ph.d. project). A study of larval development and embryology in a Nebalia species has been initiated (J. Olesen, with D. Walossek, University of Ulm). The male of the phylogenetically pivotal clam shrimp Cyclestheria hislopi has been studied and redescribed (J. Olesen, with J.W. Martin, Natural History Museum Los Angeles County, and E.W. Roessler, Universidad de los Andes, Bogotá). Description of headpores/dorsal organs in the cladoceran family Macrotrichidae has been initiated (J. Olesen, with A. Kotov, A.N. Severtsov Institute of Ecology and Evolution, Moscow). A survey of the distribution of larger Danish phyllopods has been completed (J. Olesen, with J. Damgaard, Entomology Department).
Description of tantulocarids and harpacticid copepods from the North East Water polynya (NE Greenland) have been completed, and TEM studies of the tantulocarid Polynyapodella ambrosei have been initiated (R.M. Kristensen, with R. Huys, Natural History Museum, London, and J. Høeg and N. Møbjerg, Zoological Institute).
Morphological variation in three species of the brackish water shrimp genus Palaemonetes has been studied (E. Rasmussen) A handbook in the series "Danmarks Fauna" on Danish freshwater phyllopods has been completed*. The freshwater crustacean fauna of the Nuuk area, Greenland, has been analyzed with the aim of outlining the differences between coastal, low-Arctic areas and inland, high-Arctic areas (U. Røen).
A study of Caribbean species of asellote isopods (Munnidae, Paramunnidae, Santiidae and Mexicope) has been completed (T.Wolff, with A. Brandt, University of Hamburg), and a study of a new deep-sea species of an aberrant asellote family has been initiated (T. Wolff, with M. Thiel, Smithsonian Marine Station, Florida).
The distribution, habitats and reproductive biology of two gnathiid species from the Denmark Strait and North of Iceland have been studied* (A.B. Klitgaard, ph.d. project)
The Budde-Lund types of isopods have been studied. A review of the Museum's material of the crab genera Hyas and Chionocoetes from Grønland has been initiated (P. Jeppesen).
A global revision of the amphipod genus Westwoodilla has been initiated (T. Jansen, cand. scient. project).
