    Over Oenanthe crocata L (1985)
    In:  Gorteria: tijdschrift voor de floristiek, de plantenoecologie en het vegetatie-onderzoek van Nederland vol. 12 no. 11/12, pp. 267-280
    Details
    Publikationsdatum: 2024-02-08
    Beschreibung: In 1975 two specimens of O. crocata were found in the dunes of Voorne. Since then the number increased to c. 50. The species is described and compared to other umbelliferous species, as it is likely to be mistaken for Petroselinum crispum or Apium graveolens vegetatively. Different observations on the smell of the plant and the colour of its juice are mentioned. The plant is virulently poisonous, which is illustrated with some references from literature. Its Atlantic-Westmediterranean area (fig. 2) has been reconstructed from literature and herbarium collections; somewhat uncertain is a record from Morocco. From an old collection its presence along the Northwest-coast of Italy could be confirmed. The habitats in Voorne, Normandy and Jersey are described and compared, also with records from other localities. At the localities in the northern part of France and in Holland it grows in coastal habitats characterized by a considerable seepage of fresh water rather rich in carbonates.

    Taxonomy, phylogeny and biogeography of the tridentigera group of the genus Chremistica St\xc3\xa5l, 1870 (Homoptera, Cicadidae) (1985)
    In:  Beaufortia vol. 35 no. 4, pp. 37-60
    Details
    Publikationsdatum: 2024-01-12
    Beschreibung: The tridentigera group is one of four groups within the genus Chremistica St\xc3\xa5l, 1870. Its monophyly is based upon genitalia characters. The group comprises 11 species, of which 4 are redescribed and 3 are described as new ( (C. minor, C. siamensis, C. biloba). The remaining 4 species are endemic to the Philippines and are not redescribed. A key to the males, distribution maps, a phylogenetic reconstruction and a historical biogeographic hypothesis are presented. The tridentigera group is distributed in Southern India, Sri Lanka, Thailand, Laos, Malaya, Sumatra, Kalimantan and the Philippines.

    Autoradiographic localization of 5-hydroxytryptamine and noradrenaline in the central nervous system of Lithobius forficatus L. (Myriapoda; Chilopoda) (1985)
    In:  Bijdragen tot de dierkunde vol. 55 no. 1, pp. 47-54
    Details
    Publikationsdatum: 2024-01-12
    Beschreibung: Using the ability of selective uptake by the neurons of their own secreted amines, two 3H labeled neurotransmitters were used: 5-hydroxytryptamine (5 HT, serotonin) and noradrenaline (NA). Autoradiographic study was conducted on semithin and on ultrathin sections.\nIn the brain, 3H-5 HT labeling is observed in the frontal lobes of the protocerebrum (two pairs of neurons) and in the lateral areas of the deutocerebrum and tritocerebrum (three or four pairs of neurons). A pair of labeled neurons is also present in each ganglion of the posterior part of the ventral nerve cord.\nIn the protocerebrum, 3H-NA is taken up by a pair of neurons located in the frontal lobes; two pairs of noradrenergic neurons can be found in each ganglion of the nerve cord.\nLabeled axons (5-HT and NA) are present in the brain and in the neuropils of the abdominal ganglions. The pathway of some cerebral axons can be followed in the perioesophageal connectives and in the cerebral glands.\nThese results are in agreement with the effects of injected neurotransmitters on (1) the brain electrical activity and (2) the stimulated activity of some of the protocerebral neurons (ultrastructural study by Jamault-Navarro in preparation).

    Developmental patterns in two populations of the millipede Archispirostreptus syriacus (De Saussure) in Israel (Diplopoda) (1985)
    In:  Bijdragen tot de dierkunde vol. 55 no. 1, pp. 37-46
    Details
    Publikationsdatum: 2024-01-12
    Beschreibung: Comparison between two populations of the spirostreptid millipede Archispirostreptus syriacus reveals that there are no significant differences in the pattern of development between the xeric population (in Brosh) and the mesic one (in Megiddo). However, there is a difference in the duration of larval stages resulting in higher growth rates in the xeric population than in the mesic one. In Megiddo there are 11 larval stages and maturity is reached at the age of 8 years, following 3 adult stages. In Brosh maturity is reached at the age of 6 years after 12 larval stages, followed by 4 adult stages.\nEggs that are laid in Brosh during May are significantly heavier then those laid in Megiddo during July-August. Similarly, there is a significant difference in the caloric value of the eggs from both habitats and probably in their water content as well.

    Untersuchungen zur feinstrukturellen Organisation und Funktion der Coxalorgane und Analorgane bei Chilopoda (1985)
    In:  Bijdragen tot de dierkunde vol. 55 no. 1, pp. 181-189
    Details
    Publikationsdatum: 2024-01-12
    Beschreibung: Topography and fine structural organization of coxal organs and anal organs are compared in pleurostigmophorous chilopods. Each of the coxal or anal pores leads into a cuticle-lined pore channel, the bottom of which is surrounded by a single-layered epithelium. The epithelium is composed of different cell types, except for the larval anal organs of Lithobius forficatus. The main epithelial cells show a fine structure like transport-active cells with enlargements of the cell surfaces, plasmalemma-mitochondrial complexes and a widened subcuticle. The main epithelium is surrounded by junctional cells, exocrine glands, and the cells of the pore channel. A distinct mucous layer, containing mucopolysaccharides, covers the specialized cuticle of the transporting epithelium, and is secreted by the exocrine glands. The entire epithelium is separated from the hemolymph by an inner cellular sheath.\nIn Lithobius forficatus the coxal organs transport Na+ ions into the hemolymph, resulting in an increase of the Na+ ion concentration.\nOn the other hand, the coxal organs of L. forficatus are also capable of absorbing water vapour from the atmosphere. An analogous function is assumed for the similarly structured coxal organs and anal organs of other chilopods.

    The assimilation of heavy metals by Lithobius variegatus and Glomeris marginata (Chilopoda; Diplopoda) (1985)
    In:  Bijdragen tot de dierkunde vol. 55 no. 1, pp. 88-94
    Details
    Publikationsdatum: 2024-01-12
    Beschreibung: Specimens of the centipede Lithobius variegatus and the millipede Glomeris marginata collected from uncontaminated sites, and sites contaminated with heavy metals, have been fed on tissues from the terrestrial isopod Oniscus asellus and leaf litter, respectively, containing different concentrations of zinc, cadmium, lead and copper. The extent to which these elements are accumulated by Lithobius variegatus or Glomeris marginata depends on the amounts of metals in the food and the degree of contamination of the site from which the centipedes and millipedes are collected. The tissues within the body where metals are stored are compared in the two animals and suggestions are made of the areas which are in most need of further research.

    Stadial distributions of Ommatoiulus Moreleti at different altitudes in Madeira with reference to life history phenomena (Diplopoda; Julidae) (1985)
    In:  Bijdragen tot de dierkunde vol. 55 no. 1, pp. 177-180
    Details
    Publikationsdatum: 2024-01-12
    Beschreibung: Ommatoiulus moreleti is a julid millipede native of Spain and Portugal. It has been introduced into Australia, where it has become a considerable pest, and also into Madeira, where it is now reported to be the commonest species of millipede.\nIn April and August 1981 an expediton from the University of Manchester Zoology Department visited Madeira and collections of the species were made in a variety of locations and habitats. The sex, instar and dimensions of each individual were later determined.\nThe stadial distributions at different altitudes are given for April and August.\nA pattern is found with difference in altitude which varies between the times of the year studied. This variation is discussed with reference to the climate of different parts of the island.

    Water relations in millipedes from some alpine habitat types (Central Alps, Tyrol) (Diplopoda) (1985)
    In:  Bijdragen tot de dierkunde vol. 55 no. 1, pp. 131-142
    Details
    Publikationsdatum: 2024-01-12
    Beschreibung: Five species of millipedes, living cither in a mixed oak wood (alt. 670 m) (Enantiulus nanus, Mastigona mutabilis) or in an Alnus viridis community (alt. 2000 m) ( Leptoiulus saltuvagus, Haasea fonticulorum and Ochogona caroli) and the nival species Trimerophorella nivicomes are compared in respect of their desiccation tolerance and their capacity to take up water from moist substrate.\nResults are expressed as the change of the initial water content of normally hydrated animals (\xce\x94m0, % h-1) and as the rate of transpiration per unit surface area per unit time per saturation deficit (\xc2\xb5g cm-2 h-1 mmHg-1).\nAt 0% r.h. and at 25\xc2\xb0 C, O. caroli (44.6% h-1), M. mutabilis (54.6) and H. fonticulorum (65.5) lost their water at rates higher than L. saltuvagus (9.1), T. nivicomes (9.8) and E. nanus (17.4). The tolerable water loss, expressed as a percentage of the initial body water, varied between 21 % (E. nanus) and 44.2% ( L. saltuvagus).\nThe uptake of water by eversion of rectal tissue onto moist surface seems to be an important source of water gain. Dehydrated animals of M. mutabilis absorbed at a maximal rate of 79% h-1. The ecological implications of these facts are discussed.
