Doassansiopsis caldesiae sp. nov. and Doassansiopsis tomasii: two remarkable smut fungi from Cameroon

Three recent collections of Doassansiopsis from western Cameroon are assessed taxonomically. Doassansiopsis caldesiae M. Piatek & Vánky is described as a new species from infected leaves of Caldesia reniformis (D. Don) Makino. Its diagnostic characters are flat, nonthickened sori with spore balls as blackish, slightly elevated dots, more or less globoid spores, conspicuous cortical sterile cells and parasitism on Caldesia reniformis of family Alismataceae. The species is compared to another Doassansiopsis species on host plants belonging to family Alismataceae. Doassansiopsis tomasii Vánky is described from two localities on Nymphaea nouchali Burm.f. var. caerulea (Savigny) Verdc. (Nymphaeaceae), which represents the first report of this smut from Cameroon and western Africa. Similarities between this species and Doassansiopsis nymphaeae (Syd. & P. Syd.) Thirum. and D. ticonis M. Piepenbr. are outlined and the global distribution of the three taxa is mapped. The species concept in the genus Doassansiopsis is discussed, and a key to all known species of the genus is provided.     

The life cycle of the smut fungus Moesziomyces penicillariae is adapted to the short-cycle of the host, Pennisetum glaucum

Moesziomyces penicillariae (Brefield) Vànky is a basidiomycete fungus responsible for smut disease on pearl millet, an important staple food in the sub-Sahelian zone. We revisited the life cycle of this fungus. Unlike other Ustilaginales, mating of sporidia was never observed and monoclonal cultures of monokaryotic sporidia were infectious in the absence of mating with compatible partner. These data argued for an atypical monokaryotic diploid cell cycle of M. penicillariae, where teliospores only form solopathogenic sporidia. After inoculation of monoclonal solopathogenic strains on spikelets, the fungus infects the ovaries and induces the folding of the micropilar lips, as observed during early pollination steps. The infected embryo then becomes disorganized and the fungus invades peripheral ovary tissues before sporulating. We evaluated the systemic growth abilities of the fungus. After root inoculation, mycelium was observed around and inside the roots. As argued by transmission electron microscopy (TEM) observations and polymerase chain reaction (PCR) detection using specific primers for M. penicillariae, the fungus can grow from roots to the caulinar meristems. In spite of this systemic growth, no sori were formed on the varieties of pearl millet tested after root inoculation. All together, these data suggest that the reduced life cycle of M. penicillariae – i.e. dispersal of ‘ready to infect’ solopathogenic sporidia, floral infection – is an adaptation to the aetiology of this disease to short-cycle pearl millet varieties from the sub-Sahel.

Wood ash treatment affects seasonal N fluctuations in needles of adult<Emphasis Type="Italic"> Picea abies</Emphasis> trees: a <Superscript>15</Superscript>N-tracer study

A ¹⁵N-tracer experiment was carried out in a stand of adult spruce trees [Picea abies (L.) Karst.] located on the Swiss Plateau in order to investigate the effects of wood ash treatment on seasonal nitrogen fluctuations in fine roots and needles. Treatments included irrigation (W), liquid fertilization (LF) and wood ash (A) application. ¹⁵N fluctuation in fine roots and current to 3-year-old needles was studied after one ¹⁵N pulse for 2 consecutive years (1999, 2000). ¹⁵N tracer was rapidly incorporated into the fine roots of adult trees, and ¹⁵N values reached similar levels in all treatments 2 months after the pulse. In the needles, the largest increase in ¹⁵N was observed in those of the current year. Following the initial peak during spring growth, ¹⁵N values in needles of control trees showed an oscillating pattern through the season. This oscillation is attributed to the increased use of internal N sources, as soon as the roots can no longer meet the increased N demand during the sprouting phase. However, W-, LF- and A-treated trees no longer showed the oscillation in ¹⁵N. Additional water (W and LF) as well as fertilizer (A and LF) may have induced shifts in the microbial flora, thus increasing the unlabelled N release from the soil. The strongest dampening was observed for the A treatment, indicating sufficient N availability from the soil, and making intensive use of the internal N sources unnecessary. Treatment with wood ash thus resulted in a similar fertilizer response to liquid fertilization.

An electrophoretic and morphological analysis of Labiostrongylus (Labiosimplex) bancrofti (Johnston & Mawson, 1939) (Nematoda: Cloacinidae), from macropodid marsupials,with the description of two new species

Allozyme electrophoresis was used to compare specimens of Labiostrongylus (Labiosimplex) bancrofti from two species of Australian macropodids, Macropus dorsalis and M. parryi, with a related species, L. (Labiomultiplex) uncinatus which also infests M. dorsalis. Each nematode was characterised genetically at 18 enzyme loci. The level of fixed genetic differences detected between L. (Ls.) bancrofti from M. parryi and M. dorsalis (83%) is equivalent to that when each is compared to the morphologically distinct species L. (Lm.) uncinatus (89–94%), demonstrating unequivocally that the taxon L. (Ls.) bancrofti represents at least two species, one in M. parryi and one in M. dorsalis. In addition, morphological evidence from additional specimens collected from M. parryi suggested the existence of a third sibling species in this group. All three species differ in the shape of the spicule tips; L. (Ls.) bancrofti has longer spicules than either of the two new species. L. (Ls.) quasibancrofti n. sp. has smaller cephalic papillae, larger oesophago-intestinal diverticula, a larger genital cone and a longer female tail than L. (Ls.) turnbulli n. sp. The taxon L. (Ls.) bancrofti consists, therefore, of three species, L. (Ls.) turnbulli in M. parryi, L. (Ls.) quasibancrofti in M. dorsalis, and L. (Ls.) bancrofti found in both host species, as well as in four species of rock wallabies.     

A new classification for the subgenera of the genus Acanthophthirius Perkins,with descriptions of twelve new taxa (Acarina,Trombidiformes, Myobiidae)

The myobiid genus Acanthophthirius Perkins, to date comprising four subgenera, is reviewed and divided into just two subgenera, the nominate subgenus and Myotimyobia Fain. The male genital shield and female opisthogastric sclerites, which are here considered to be part of female genitalia, are adopted as the criteria for dividing the subgenera. These structures are essentially the same in form and position in the subgenus Acanthopthirius in its revised sense, while they are both more heterogeneous in species of the redefined subgenus Myotimyobia. The subgenera Acanthophthirius Fain and Chiromyobia Fain are thought to represent species-groups in the nominate subgenus, named respectively the etheldredae and miniopteri groups. The following one new subspecies and 11 new species are described: A. (A.) womersleyi eptesicus, A. (A.) glauconycteris, A. (A.) mauritaniensis, A. (A.) philetoris, A. (A.) otonycteris, A. (A.) steatocaudatus, A. (A.) nyctophilis, A. (M.) vagus, A. (M.) longus A. (M.) baueris, A. (A.) hesperopteris (female only) and A. (M.) pixonixeos (female only). A. (M.) hanensis is synonymised with A. (M.) namurensis, and A. (M.) capacini is emended to A. (M.) capaccinii and relegated to a subspecies of A. (M.) myotis. All the known and new species are assigned to their respective subgenera and shown in a table. Incongruent host-relationships of some of the mites are clarified, although not completely solved, by the introduction of the new classification for the subgenera.

A new species of Ceratozamia (Zamiaceae, Cycadales) from Veracruz, Mexico

Ceratozamia huastecorum sp. nov. is from an isolated meseta or tepui-like mountain in the Huasteca region of northern Veracruz State, Mexico. It has affinity to C. morettii Vázq.Torres & Vovides from the Mexican transvolcanic mountain range, which lies over 200 km to the south. The most notable differences are in female cone colour, leaf and leaflet morphology and length. The specific epithet is chosen in honour of the Huasteca ethnic region of great cultural importance to northern Veracruz.  © 2003 The Linnean Society of London, Botanical Journal of the Linnean Society , 2003, 141 , 395–398.     

Morphological variation of the five vole species of the genus Microtus (Mammalia,Rodentia, Arvicolinae) occurring in Greece

Morphometric data for the five vole species of the genus Microtus living in Greece are old, sparse, poor and insufficiently analysed. This work aims to give the first comprehensive morphometric analysis of body and skull inter‐ and intraspecific variation for M. (M.) guentheri, M. (M.) rossiaemeridionalis, M. (Terricola) subterraneus, M. (T.) felteni and M. (T.) thomasi, applying multivariate statistics to 28 linear morphometric variables. It was based on ample material (202 adult individuals) using samples from localities that adequately cover the entire distributional range of each species in Greece. The five species and the two subgenera (Microtus and Terricola) were morphometrically clearly distinguished and discriminating variables were revealed. However, morphometrics did not provide robust criteria to infer phylogenetic relations among species. Furthermore, three species, M. (M.) guentheri, M. (M.) rossiaemeridionalis and M. (T.) thomasi, exhibited considerable intraspecific size or shape variation, which was mostly random and not associated with geographical proximity. Comparisons with data in the literature, mainly concerning populations of these species from adjacent areas, indicate that the Greek M. (M.) guentheri, M. (M.) rossiaemeridionalis and M. (T.) thomasi tend to be smaller than their conspecifics, while M. (T.) subterraneus and M. (T.) felteni are about equal in size to their Balkan relatives.     

Morphological evolution and phylogenetic relationships of the European ground voles (Arvicolidae, Rodentia)

Brunet-Lecomte, P. & Chaline, J. 1991 01 15: Morphological evolution and phylogcnctic relationships of the European ground voles (Arvicolidae. Rodentia). Lethaia. Vol. 24. pp. 45–53. Oslo. ISSN 0024–1164. A new morphological study of the first lower molar M₁ of European Quaternary ground voles (Arvicolidac. Rodcntia. Microtus (Terricola)) by means of multivariate analysis renews the systematics. phylogenetic relationships and their evolutionary group history. An Allophaiomyan origin of ground voles has been confirmed and the evolution of Mediterranean and middle Europcan groups has now been clarified. Primitive species of middle European groups display plesiomorphics. except for M. (T.) arvalidens, which shows certain apomorphies of the present species. The occurrence of M. (T.) multiplex in France at the end of the middle Pleistocene before the appearance of M. (T.) suhterraneus completely reverses previous ideas which considered that M. (T.) multiplex was a sibling species derived from M. (T.) subterraneus during the Würmian glaciation. The Atlantic species M. (T.) pyrenaicus is probably derived from the middle Pleistocene species M. (T.) mariaclaudiue whose exact origin is unknown. M. (T.) sauii, M. (T.) tarentina. M. (T.) melirensis and M. (T.) henseli belong to the same geographic group. Perhaps M. (T.) savii derived from M. (T.) tarentina or shares the same ancestor with M. (T.) tarentina. M. (T.) duodecimcostarus probably indirectly derived from an Iberian specics of Allophuiomys such as A. chalinei, while M. (T.) lusitanicus was separated from M. (T.) duodecimcostutus about 60,000 years ago. A sketch of the stratigraphical records and geographical distribution of the Terricola species in Western Europe showing their phylogenetic relationships and migrations during the middle and upper Pleistocene is included.

穗状狐尾藻与不同生长期苦草种间竞争研究

水生植物之间的竞争作用在水体生态系统恢复过程中具有重要作用。本研究采用取代系列实验方法,对穗状狐尾藻(Myriophyllum spicatum L.)与不同生长期(幼苗期和成株期)苦草(Vallisneria natans(Lour.)Hara)的种间竞争进行了研究。结果显示,对于不同生长期的苦草,穗状狐尾藻均具有较强的竞争优势,成株期苦草的竞争能力强于其幼苗期;苦草成株组中的穗状狐尾藻平均株高比苦草幼苗组中的穗状狐尾藻平均株高增加了128.6%(P0.05),但苦草成株组中的穗状狐尾藻植株平均干重比苦草幼苗组中的穗状狐尾藻植株平均干重降低了62.8%(P0.05);苦草幼苗组中的穗状狐尾藻分枝较多、株丛大,对苦草幼苗形成了较大的遮光作用;苦草成株组中的穗状狐尾藻分枝少、植株较长,顶端漂浮于水面生长,表明受苦草的种间竞争压力增大,但仍小于穗状狐尾藻的种内竞争;另外,苦草幼苗组中的苦草根长比苦草成株组中的苦草根长平均长28.6%(P0.05),表明在与穗状狐尾藻竞争过程中,苦草幼苗更趋于竞争地下资源。本研究结果说明穗状狐尾藻竞争能力强于苦草,苦草幼苗受穗状狐尾藻的竞争影响较大。
