    Reviews (1997)

    Description: The International Conference \xe2\x80\x98Compositae: Systematics, Biology, Utilization\xe2\x80\x99 held in 1994 inspired the authors, on the suggestion of Dr. K. Ferguson, to publish a book accommodating more general systematic papers on Asteraceae, resulting in the present work. It contains seventeen chapters [in English, French (1), and Spanish (1)], including the Introduction by C. Jeffrey, and is provided with a taxonomic index. Following the Introduction, Jeffrey gives a review of the developments in Asteraceae systematics during the last 20 years, since the conference of 1975. I agree with him that improvements are possible in the use of cladistic analysis in taxonomy, but it seems to me that his review is a bit too negative in this respect. \nAdvances in Compositae Systematics presents studies at many different taxonomical levels, from macromorphology to molecular systematics and chemistry. The sequence of the chapters seems rather arbitrary; however, starting with a paper dealing with the origin of the Asteraceae seems very logical. In this chapter DeVore & Stuessy argue that the Asteraceae originated in late Eocene on the South America-Antarctica-Australia supercontinent. The Calyceraceae and Goodeniaceae would be families most closely related to the Asteraceae. DeVore & Stuessy used information on (pollen) morphology, present distribution, fossil records, and geology to reach their conclusions.

    The Miocene fish Marosichthys, a putative tetraodontiform, actually a perciform surgeon fish (Acanthuridae) related to the recent Naso (1997)
    In:  Beaufortia vol. 47 no. 1, pp. 1-10
    Details
    Publication Date: 2024-01-12
    Description: Marosichthys huismani (de Beaufort, 1926), a fish from the Miocene of the Celebes, was described in the tripod fish family Triacanthidae, Tetraodontiformes. It is shown here to be a valid genus of the surgeon fish family Acanthuridae, Perciformes, and closely related to the Recent genus Naso. Marosichthys is unique among all acanthurids in having the ventral shafts of the first two basal pterygiophores of the spiny dorsal fin in the preneural space (versus only one in front of the first neural spine) and no vacant interneural spaces (versus the third space vacant).

    Precopulatory mate guarding and mating in Tachidius discipes (Copepoda: Harpacticoida) (1997)
    In:  Contributions to Zoology vol. 66 no. 4, pp. 201-214
    Details
    Publication Date: 2024-01-12
    Description: Precopulatory mate guarding and mating behaviour of Tachidius discipes Giesbrecht, 1881, has been analysed using a video camera mounted on a microscope. Males preferably accompany fourth or fifth stage female copepodids during precopulatory mate guarding; only rarely are third copopodid stages guarded. Rare cases of males clasping juvenile males are also known. Males are active during mate guarding and constantly change the site of attachment of their antennules. This behaviour may ensure continued association of the adult male with the juvenile copepodid when the latter moults during the mate guarding phase.\nThe final moult of the female, once observed only, lasts only 2 minutes. Copulation immediately follows but is preceded by the male\xe2\x80\x99s control of the genital field of the female. This is done by the second, third and fourth legs of the male sliding over the female\xe2\x80\x99s genital field. Males copulate only with virgin females. A male will also copulate with a female that he has not guarded during her juvenile state. Previously inseminated adult females are rejected. Their condition is recognized even when the spermatophore has fallen off and when no egg sac is carried. Copulation takes only a few seconds. The spermatophore is transferred without the aid of any appendage and the male separates from the female shortly afterwards.\nMales of T. discipes were found to have either one or two spermatophores in their gonoduct. Those with two were able to inseminate two females within about two to three hours. After the first or, in the case of a male with two spermatophores, after two copulations, 12.5 to 24 hours elapsed before he was able to inseminate another virgin female. Females are passive when investigated by a male and make no attempt to repel him. In T. discipes, a species exhibiting typical precopulatory mate guarding, male choice is a strongly expressed behaviour while female choice is not expressed.
