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.
The aqueous extract of Dumortiera hirsuta (Swaegr.) Nees, a bryophyte, was found to be effective against seven postharvest phytopathogens tested. The fungitoxicity of the extract was measured by percent spore germination inhibition and percent radial growth inhibition using poisoned food technique. The inhibition of spore germination by the Dumortiera extract was within the range of 400 to 550 ppm. In poisoned food technique, out of seven postharvest phytopathogenic fungi tested six were completely inhibited by the Dumortiera extract with concentration range of 550 to 600 ppm. The mode of action of extract (350 ppm) was examined in the case of Aspergillus niger van Tieghem. Distinct morphological changes were observed in treated hyphae in comparison to control . The treatment clearly showed anomalies in the hyphae; cell wall of became flaccid, cytoplasm started leaving the cell wall and became granulated.
Parson’s valley is an area explored for the first time in Indian Bryology; it is situated in Nilgiri hills (Western Ghats). The region is very conducive for the growth of liverworts and it is evident by the present study of recent collections from this area in which 27 taxa (under 12 genera and 5 families) of liverworts have been recorded, of which few are new to Nilgiri hills as well as south India.
Keys and diagnoses of North European aphids (Hemiptera, Aphidoidea) associated with mosses, horsetails and ferns are given, based on fresh and freeze-dried material. Numerous externally visible and thus informative characters, that are absent in cleared, slide-mounted specimens, such as body shape colours, wax coating and pattern etc., are utilized. Most of the species are illustrated by photographs of live specimens and drawings. Root-feeding species living in the moss layer or otherwise often present in moss samples are also included, even if their hosts were spermatophytes. The combination of colour images and diagnoses, utilizing easily observed characters, allows the identification of a large number of species already in the field, and many more at home with the aid of a stereo microscope. Host plant relationships and association with ants are summarised, including new records. Brief accounts on aphid life cycles, freeze-drying preparation techniques, etc. are also given to support the use of the keys.

Review of Neurepyris Kieffer, 1905 (Hymenoptera, Bethylidae), a new synonym of Pristocera Klug, 1808
(2011)
The genus Neurepyris Kieffer, 1905 is revised. The adult male holotypes N. rufiventer Kieffer, 1913 from Eritrea and N. tagala (Ashmead, 1905) from the Philippines are redescribed and illustrated. Both species are transferred from the subfamily Epyrinae to Pristocerinae because they have the metanotum well developed medially. Neurepyris rufi venter is transferred to Pristocera Klug, 1808 because the hypopygium is deeply divided into two apical lobes, the subdiscoidal and cubital veins do not reach the border of the forewing, the pronotal disc has the anterior region slightly elevate medially, and the stigma is elongate. Neurepyris tagala is transferred to Apenesia Westwood, 1874 because the basal tooth of mandible is not curved inward, the median lobe of clypeus is not depressed near the antennal insertions, and the aedeagus consists of one lamina. The genus Neurepyris is considered a junior synonym of Pristocera because its type species is N. rufiventer.
