    Notes: We conducted an experiment with the dual aims of (1) examining the feasibility of establishing a species-rich grassland using a commercially available grass and wild-flower seed mixture and (2) examining the effects of different defoliation and fertilizer managements on the productivity, species richness, diversity, and composition of a species-rich grassland established on a site reclaimed after opencast coal mining. The use of the seed mixture successfully established a sward of some 18–25 species per square meter. The species composition was enriched to some extent by recruitment of unsown species, principally from the soil seed bank. Hay-type defoliation management produced greater dry matter yield and species richness than grazing defoliation, but grazing defoliation produced greater species diversity. Fertilizer application had no significant effect on dry matter production but reduced species diversity. Ordination analysis revealed that both defoliation and fertilizer management significantly affected species composition. The response obtained by individual species was explicable largely by their comparative biology.

    Notes: Abstract. The neutron deficient 199At nucleus has been studied in the 175Lu+28Si reaction at Eb= 141 MeV. In order to select events of interest in the presence of the very strong background caused by fission, γ-rays have been detected in coincidence with recoiling evaporation residues. The excited states of 199At observed for the first time may indicate that this nucleus is deformed.

    Notes: Abstract The58Ni(30Si,αpn)82Y reaction at a beam energy of 134 MeV was used to populate the odd-odd nucleus82Y and coincidentγ rays depopulating high spin states in the evaporation residues were detected with the EUROGAM Phase 2 array. A superdeformed structure has been observed with an intensity of 1.5±0.5%. The cascade of 9 coincidentγ rays has consecutive energy spacing of ∼160 keV. This corresponds to a dynamic moment of inertia which is almost constant at approx mately 25h 2 MeV−1. The band is interpreted as a signature=0, negative parity SD band with aπ51 V52 intrinsic intruder configuration.

    Description / Table of Contents: Résumé Les insecticides pyrethroïdes ont été utilisés pour lutter contre les pullulations d'araignées rouges. Cette note examine les réponses de Tetranychus urticae Koch et des prédateurs phytoseiidés résistants aux organo-phosphorés, Amblyseius fallacis Garman et Typhlodromus occidentalis Nesbitt, au fenvalerate (pyrethroïde) et à l'azinphosmethyl (organophosphate). Quelques essais avec du carbaryl sont indiqués. Une femelle adulte de T. urticae est placée sur une rondelle de feuille de Phaseolus vulgaris L. pulvérisée dans une tour de Potter. Les résultats sur la mortalité en fonction de la dose obtenus montrent une activité plus rapide du fenvalerate que de l'azinphosmethyl. Les DL50 du fenvalerate (0,056 et 0,051g AI/I) sont les mêmes à 24 et 48 h, tandis que l'azinphosmethyl montre une activité plus lente (DL50 de 0,72 et 0,38g AI/I à 24 et 48 h). La mortalité se partage entre la sortie de la rondelle et la mortalité in situ. Le fenvalerate provoque une plus forte répulsion que l'azinphosmethyl. Contrairement à l'azinphosmethyl le fenvalerate inhibe la production d'oeufs 60% et 20% d'inhibition à DL50 au bout de 24 h par rapport au témoin. Cette inhibition n'est pas permanente. Le carbaryl n'a pas d'effets inhibiteur ou acaricide à 1g AI/l. Les femelles adultes de T. urticae décèlent les résidus de fenvalerate sur les rondelles et pondent leurs oeufs sur les moitiés non traitées ou traitées à l'azinphosmethyl. Les Phytoseiides sont très sensibles aux résidus de fenvalerate. Après consommation d'oeufs traités, A. fallacis est incapable d'éviter des bandes gluantes. T. occidentalis décèle des traitements à 0,00005g AI/l en quittant les lames traitées par les bandes gluantes.
    Notes: Abstract The pyrethroid fenvalerate showed significantly faster activity against adult ♀ two-spotted spider mite Tetranychus urticae Koch c.f. azinphosmethyl using broad bean leaf discs sprayed in a Potter tower. LC50s for fenvalerate were similar at 24 and 48 hr (0.056 and 0.051g AI/1) while LC50s for azinphosmethyl were significantly different at 24 and 48 hr (0.72 and 0.38g AI/1, respectively). Mortality was partitioned to run-off and direct mortality. Fenvalerate showed an increasing contribution to mortality by run-off with increasing concentration. Increasing concentrations of azinphosmethyl had no effect on the proportion of T. urticae running off the discs. Fenvalerate inhibited egg production c.f. azinphosmethyl (60% and 20% inhibition respectively c.f. control after 24hr). The effect was not permanent. Carbaryl showed no acaricidal or inhibitory effects at 1g AI/1. T. urticae detected fenvalerate residues as reflected by choice of oviposition sites on untreated halves of leaf discs c.f. treated halves. Azinphosmethyl had no effect on oviposition preference. Phytoseiid mites were highly sensitive to fenvalerate residues. Predators moved off the test arena into sticky barriers after feeding on fenvalerate-treated eggs or walking on glass slides treated at 0.00005g AI/1.

    Description / Table of Contents: Zusammenfassung Die AI(Nb, Ta)Ti−2 Substitution im Titanit: Auftauchen einer neuen Mineralspecies? Die höchsten (Nb, Ta) Gehalte, die jemals für Titanit gefunden wurden, werden für den Maršíkov II Pegmatit in Nordmähren, Tschechei, berichtet. Der Intrusivgang ist Teil eines Amphibolit-faziell überprägten Pegmatitschwarms vom Beryll-Columbit Subtypus Der Pegmatit führt u.a. seltene tantalbetonte Rutile verwachsen mit titanbetontem Ixiolith, titanbetontem Columbit-Tantalit, Fersmit and Mikrolith. Deformationsbedingte Frakturen in den (Nb, Ta) Oxiden sind mit Titanit, als Folge der Reaktion der metamorphen Porenlösungen mit den Oxidmineralen, verkittet. Titanit zeigt begrenzte Substitutionen Na(Ta 〉 Nb)(CaTi)−1,(Ta 〉 Nb)4□Ti−4Si−1 and Al(OH, F)(TiO)−1, aber extensive (und gelegentlich einzig bedeutsame) Substitution (Al 〉〉 Fe3+)(Ta 〉 Nb)Ti−2, die eine weitverbreitete, oszillierende Zonierung hervorruft. Diese Substitution verringert den Anteil der Titanit-Komponentesensu stricto, CaTiSiO,O, auf weniger als 50 Mol% in vielen Analysen. Die Extremzusammensetzung entspricht Ca0.994Na0.11) (T10.436Sn0.007Al0.280Fe3+ 0.006Ta0.199Nb0.079)Si0.988O4(O0.974F0.026). Das AusmaB dieser Substitution ist unzureichend, um eine neue Mineralspecies zu definieren.
    Notes: Summary The highest (Nb, Ta) content ever encountered in titanite is reported from the Maršíkov 11 pegmatite in northern Moravia, Czech Republic. This dike is a member of a pegmatite swarm of the beryl-columbite subtype, metamorphosed under conditions of the amphibolite facies. The pegmatite carries, i.a., rare tantalian rutile intergrown with titanian ixiolite, titanian columbite-tantalite, fersmite and microlite. Fissures generated in the Nb, Ta oxide minerals during deformation are filled with titanite, formed by reaction of the oxide minerals with metamorphic pore fluids. The titanite displays limited degrees of substitutions Na(Ta 〉 Nb)(CaTi)−1, (Ta 〉 Nb)4□Ti−4Si−1 and AI(OH, F)(TiO)−1, but an extensive (and occasionally the sole significant) substitution (Al 〉 Fe3+)(Ta 〉 Nb)Ti−2, responsible for widespread oscillatory zoning. This substitution reduces the proportion of the titanite componentsensu stricto, CaTiSiO4,O, to less than 50 mole % in many analyzed spots. The extreme composition corresponds to (Ca0.994Na0.011)(Ti0.436Sn0.007Al0.280Fe3+ 0.006Ta0.199Nb0.079)Si0.988O4(O0.974F0.026). However, so far this substitution fails to generate compositions that would define a new species.

    Description / Table of Contents: Zusammenfassung In 11 bis 60 Proben von Biotit, Muskovit und Lepidolith aus den Pegmatiten von Rožná (Typlokalität des Lepidoliths; 323 ± 9 Ma) in Westmähren wurden Chemie, Struktur-parameter, Polytypie, optische Eigenschaften und Rb-Sr-Isotopie untersucht. An beiden Lokalitäten wird früher Biotit an Endokontakten nach Innen von Muskovit und Lepidolith gefolgt, letzterer ist in und um den Kern konzentriert. In Rožná folgt 1M-Lepidolith auf 2M1-Muskovit, aber alle späteren Lepidolithgenerationen sind 2M2, nahe Tri50Ply50 und zum Teil mit 2M1-Muskovit vergesellschaftet. In Dobrá Voda sind alle Lepidolithe vom Typ 1M und frei von Muskovit, die späten Varietäten kommen Tri50Ply50 nahe. An beiden Lokalitäten ist während des Fortschreitens der Glimmerkristallisation eine Tendenz von steigendem μHF angezeigt, die in der Ausfällung von Topas ihren Höhepunkt findet. Die Polytypie des Lepidoliths kann nicht mit irgendeiner Eigenheit der Zusammensetzung oder des Wachstums korreliert worden, auch nicht mit einer Kombination von diesen. Während der ganzen Glimmerkristallisation nimmt Rb/Cs ab, aber die Tendenz von K/Rb ändert sich nach anfänglichem Abfall. Das Bor verteilt sich bevorzugt auf den Muskovit (bis zu 1.10 Gew. -% B2O3), aber die Be-, Zn-, Mn- und Sc-Gehalte sind im Lepidolith erhöht. Ein leichter Ansteig von Fe, Ba und Cl in der letzten Lepidolithgeneration könnte vielleicht durch eine Mischung von pegmatitischen Restlösungen mit metamorphen Porenlösungen verursacht sein.
    Notes: Summary The chemistry, structural parameters, polytypism, optical properties and Rb-Sr isotopes were examined in 11 to 60 samples of biotite, muscovite and lepidolite from the pegmatites at Rožná (the type locality of lepidolite; 323 ± 4Ma) and Dobrá Voda (306 ± 9Ma) in western Moravia. At both localities, early endocontact biotite is followed inwards by muscovite and lepidolite, which is concentrated in and around the core. At Rožná, a 1M lepidolite follows after 2M1 muscovite but all later generations of lepidolite are 2M2, close to Tri50 Ply50 and in part associated with muscovite 2M1. At Dobrá Voda, all lepidolite types are 1M and free of muscovite, and the late varieties approximate Tri30 Ply70. At both localities, a trend of increasing μHF is indicated during the progress of mica crystallization, culminating in precipitation of topaz. Polytypism of lepidolite is not correlatable with any compositional or growth feature, or their combination. Throughout the mica crystallization, Rb/Cs decreases but K/Rb becomes reversed after an initial decrease. Boron is partitioned preferentially into muscovite (up to 1.10 wt.% B2O3) but Be, Zn, Mn and Sc are enhanced in lepidolite. A slight increase in Fe, Ba and Cl in the last generation of lepidolite might be possibly due to mixing of residual pegmatite fluids with metamorphic pore solutions.
