The variability of the reticulum pattern, ornamentation and outline of the Urocythereis populations of the La Strea Bay is analysed. The results show that the shell features of the form U. distinguenda (Neviani, 1928) (= U. oblonga Brady, 1866) have to be included within the high variability range of U. margaritifera (G.W. Müller, 1894). Consequently, it is suggested that in the upper infralittoral waters of the inlet two (and not three, as stated in previous investigations) species of the genus Urocythereis presently live. A second form, displaying a relatively low variability, is described as a new species, U. ilariae sp. nov.
A catalogue of aphidiine parasitoids (Hymenoptera: Braconidae: Aphidiinae) associated with various aphids species occurring in India was compiled. The present catalogue with 125 species under 22 genera has been further reinforced with not only all the latest taxonomic changes but also host names, host plants, distribution in India etc.
We revise the genus Attemsostreptus Verhoeff, 1941 based on type material of the type species, A. costatus Verhoeff, 1941, synonymise A. orobius (Kraus 1958) with A. costatus and describe a second species of the genus, A. reflexus sp. nov., collected from Kimboza Forest Reserve in Tanzania, and discuss the dubious tribe Trachystreptini.
In this work we present a revision of the genus Ommatoiulus Latzel, 1884 in Portugal. Based on recently collected material and older museum samples, including type specimens, we describe six new species to science, viz. Ommatoiulus alacygni sp. nov., O. camurus sp. nov., O. denticulatus sp. nov., O. litoralis sp. nov., O. staglae sp. nov. and O. stellaris sp. nov. The species O. alacygni sp. nov., O. denticulatus sp. nov. and O. staglae sp. nov. described from the Algarve are outstanding by their extremely reduced mesomerital process. The species O. porathi (Verhoeff, 1893) and O. andalusius (Attems, 1927) are recorded and redescribed for the first time after their original description. The finding of O. andalusius – originally described from Andalusia in Spain – constitutes a new record for Portugal together with two species, viz. O. fuentei (Brolemann, 1920) and O. martensi Mauriès, 1969. The taxonomic status of several species is revised. Thus Archiulus (Schistocoxitus) cingulatus Attems, 1927 is here considered as a junior synonym of Ommatoiulus lusitanus (Verhoeff, 1895) while Schizophyllum cervinum Verhoeff, 1910 is synonymized with Ommatoiulus moreleti (Lucas, 1860). An identification key to all hitherto known Portuguese species of Ommatoiulus is presented as well as a distribution map illustrating the various species occurrences in the country.
Die Interpretation der Moses-Ḫiḍr-Erzählung in Ibn ʿArabīs Werken „al-Futūḥāt al-Makkīya“und „Fuṣūṣ al-ḥikam“
Die Moses-Ḫiḍr-Erzählung in den Versen 60-82 der Sura Kahf, der in der sufischen Tradition eine enorme Bedeutung zugemessen wird, wurde im Laufe der Geschichte zum Gegenstand unterschiedlicher Interpretationen. Es besteht somit kein Zweifel, dass eine der bemerkenswertesten dieser Interpretationen, die einen besonderen Platz in der Geschichte des Sufismus hat, von Ibn ʿArabī stammt. Er bewertete die Ereignisse zwischen Moses und der koranischen Figur, die er entsprechend der Tradition „Ḫiḍr” benannt hat, anders. Neben der literarischen Bedeutung der Personen und Ereignisse, die in der Erzählung vorkommen, etabliert Ibn Arabi dazu neue Zusammenhänge, indem er zu deren verborgenen Bedeutungen übergeht. Nach ihm ist nichts so, wie es scheint
This paper is part of a project of studying benthic diatom biodiversity on marine coastal regions of Sweden with focus on rare and less known species. Two new species of Cocconeis Ehrenb. are described from Vrångö, a small island in the west coast of Sweden. Both species were found as epiphytic on the green alga Ulva intestinalis L. Cocconeis magnoareolata Al-Handal, Riaux-Gob., R.Jahn & A.K.Wulff sp. nov. is a small species not exceeding 9 μm in length and characterized by having large subquadrangular areolae on the sternum valve. Cocconeis vrangoensis Al-Handal & Riaux-Gob. sp. nov. appears similar to some taxa of the 'Cocconeis scutellum complex', but differs by its stria density on both valves and variable features of the areola and valvocopula ultrastructure. Detailed descriptions based on light and electron microscopy examination, a comparison with closely related taxa, as well as a description of the habitat of both species are here presented.
The present study is a compilation of moss flora of Western Himalayas (India). This compilation listed 745 species of mosses, belonging to 19 orders; 55 families and 230 genera. Out of these 17 species have been reported endemic from Western Himalayas. 196 species have been synonymized and status of 86 species is still doubtful i.e. unresolved name. At present out of 745 only 463 species are validly known from this mountain range of India
In the present study the level of S, Cu, Cr, Cd, Zn, Pb and Cr was estimated in samples of the common thalloid liverwort Plagiochasma rupestre (G. Frost) Stephani, from Ranthambhore National park, Rajasthan (India). High metallic load was observed both in substrate as well as in plant tissue at locations adjacent to higher vehicular load, during winter the metallic content is highest, followed by summer and monsoon season. Elemental concentration in substrate for Plagiochasma rupestre was in the order of Zn> S> Pb> Cu> Cd> Cr, while in plant tissue it showed S> Zn> Pb> Cu> Cd> Cr, which is indicative of air borne trace elemental load. Quantitative analysis of these elements in vegetative thalli of Plagiochasma rupestre and the substrate showed an increase in metallic content during winter, which reveals the significance of this liverwort as a biological sink of mineral elements present in the soil and air and may provide an important tool in estimation of both aerial pollution and mineral enrichment in soil.
The present contribution is an enumerated account of mosses of Munsyari (Pithoragarh), Western Himalayas. The study revealed the presence 8 orders, 20 families, 32 genera and 44 species in the area. Moss species viz. Anoectangium walkeri Broth., Actinothuidium hookeri (Mitt.) Broth. Stereophyllum ligulatum Jaeg., Anomodon minor (Hedw.) Fŭrnr., Hageniells assamica Dixon, Schoenobryum cocavifolia (Griff.) Gang., Entodon luteonitens Ren. et Card. and Physcomitrium pulchellum (Grif.) Mitt. are reported for the first time from Munsiyari hills as well as western Himalayas as welcome additions to the bryoflora of Uttarakhand (Western Himalaya).
Similipal Biosphere Reserve is a part of biotic province of Chhotanagpur Plateau. It has a representative ecosystem under Mahanadian biogeographic region. Its biodiversity is an assemblage representation of Western Ghats and North-East India. Regarding bryophytes this area was rather unexplored and the current investigation shows the occurrence of 33 taxa of bryophytes in this biosphere reserve and its neighboring areas. Each species has been enumerated with its ecological and distributional details.
Since the existence of Nilgiri hills, bryophyte- the miniatures of plant kingdom play an important and crucial role in the stabilization of Blue Mountains ecology. Unlike Himalayas, the landslides were rare in the area, but with the time and changing global environment it had become a common sight. Significantly ever increasing population and vehicular traffic is the prime reason for them, to cater the need, roads are periodically broadened by cutting road sides destroying the habitat as also the inhabiting species. Bryophytes, are efficient soil binders that regulate the soil moisture and provide substrate for future plant succession. The habitat loss and nudeness of substratum gives impetus to rapid soil erosion that further enhances the problem of their very survival. The present communication provides significance of these avascular cryptogams in environmental assessment, ecological balance and their role in decreasing the pore pressure to check land slides.
In succession of terrestrial ecosystem, bryophytes, algae and lichens constitute the primary components. Not only phylogenetically but also physically they are related to each other, as they are also found in close association and intermixed with each other on same substratum. A chlorophycean alga Ulothrix zonata (Weber & Mohr) Kützing has been found growing as an epiphyte on moss Macromitrium sulcatum (Hook.) Brid.. The association is peculiar as the algal filaments form a close net over the surface of moss leaves and axis.
Bryoflora of Munsyari and Dharchula Tehsil of Pithoragarh, Uttarakhand, Western Himalayas, India
(2012)
Uttarakhand state of India comprises unique topographical conditions and hence is rich in bryophytes. In present work two Tehsils-Munsyari and Dharchula of Pithoragarh have been explored extensively to assess the bryophytic wealth of this district. A preliminary checklist has been prepared which revealed the occurrence of 51 taxa of bryophytes from this district.
India is among of the 12 mega biodiversity countries in the world. The huge area and the range of phyto-climatic conditions met within its eight bio-geographical zones contribute to the great diversity of the Indian flora. These bio-geographical zones have diverse topographical variations and climatic conditions. The present work deals with the bryo-diversity of western part of the country which is greatly neglected due to its comparatively harsh environmental conditions by the bryologists. It is an attempt to provide a comprehensive account of the bryophyte wealth of the region by stepwise exploration and it has initiated with Ranthambhore National Park.
The present contribution revealed the occurrence of Hypnum plumaeforme Wilson belonging to family Hypnaceae (Bryopsida) for the first time in Munsiyari region of Uttarakhand state, which is a new addition to the bryoflora of Western Himalayas. Earlier this species was known only from eastern Himalayas (Nepal).
Scanning electron microscope analyses of sporoderm of 7 species of 3 genera of Marchantiales are presented in this study. In the studied species, sporoderm exhibit a broad range of morphology and have taxonomic specificity. The structurally rigid sporoderms have specific sculpturing and characteristic patterning. Peculiar architectures are found in different taxa, which revealed that and stable architectures may be present within an order. Sporoderms usually have specific surface markings which are often one of the best parameters to identify any species.
