New data and new species of Microcoryphia and Zygentoma (Insecta) from Israel

The presented contribution concerns the study of several samples of Microcoryphia and of Zygentoma obtained in Israel; an up to date of the species of these insect Orders reported from Palestine is also presented. Genus Hyperlepisma (Lepismatidae: Ctenolepismatinae) is reported for the first time from the country and one new species H. palaestinensis n. sp., is described from the northern Negev. Another new species this one of the genus Lepidospora s. s. (Nicoletiidae: Coletiniinae), L. (L.) ayyalonica n. sp., is described from the Ayyalon Cave in Western Central Israel, from where several other terrestrial and aquatic endemic arthropods were already known.     

The known species of <Emphasis Type="Italic">Psilocybe</Emphasis> (Basidiomycotina,Agaricales, Strophariaceae) in Nepal

Psilocybe percevalii, P. pseudobullacea, and P. subcubensis are reported for the first time from Nepal. Of these threes the latter is the only species with neurotropic properties. Previously, only P. montana and P. coprophila have been reported from Nepal. Psilocybe coprophila, as reported from Nepal, probably represents P. pseudobullacea.

Species diversity of bats (Mammalia: Chiroptera) in Iwokrama Forest, Guyana, and the Guianan subregion: implications for conservation

Fourteen species of bats are reported for the first time from Guyana (Saccopteryx gymnura, Micronycteris brachyotis, M. homezi, Lichonycteris obscura, Anoura latidens, Vampyressa pusilla, Vampyrodes caraccioli, Eptesicus chiriquinus, Cynomops paranus, Molossops neglectus, Molossus sp., Molossus coibensis, Molossus sinaloae, and Promops centralis) bringing the known bat diversity for the country to 121 species. Information including measurements, reproductive data, distribution, and taxonomy are provided for these species. Seven of these new records were collected in the Iwokrama International Rain Forest Programme site in central Guyana. Eighty-six bat species are now documented from Iwokrama Forest which is the highest species diversity for bats reported from any protected area in the world. There are, however, few tropical sites that have relatively complete inventories. A summary for bat species diversity in southern Venezuela, Guyana, Suriname, and French Guiana indicates that at least 146 species of bats are known from the Guianan subregion. Intense inventory surveys, especially in the often neglected subcanopy, suggest that species richness is probably underestimated in most Neotropical areas. Likewise, species-level diversity in the Guianan subregion is higher than previously suggested. Surveying and monitoring biodiversity are critical to developing a National Protected Areas System in Guyana.     

Reproductive biology of skates, Bathyraja(Ishiyama), along the eastern Bering Sea continental slope

Eight Bathyraja skate species, Bathyraja aleutica, Bathyraja interrupta, Bathyraja lindbergi, Bathyraja maculata, Bathyraja minispinosa, Bathyraja parmifera, Bathyraja taranetzi and Bathyraja trachura, collected along the eastern Bering Sea continental slope were examined for reproductive features. The sex ratio for six of eight Bathyraja skate species studied was c. 1 : 1 with males dominating for B. interrupta and B. parmifera. Five of eight species examined, B. aleutica, B. lindbergi, B. parmifera, B. taranetzi and B. trachura approximately equalled or exceeded the maximum reported total length, L_T. Maximum L_T for three species (B. interrupta, B. minispinosa and B. parmifera) revealed that the largest individuals were males and that in three other species (B. lindbergi, B. maculata and B. trachura) both females and males grew to approximately the same size. Both females and males matured at approximately the same L_T for seven of eight species. Only female B. aleutica matured at a much larger size than males. All species matured within a narrow size range following a protracted juvenile stage and once mature these skates appeared to grow very little. First maturity for all species occurred at ≥80% of their maximum L_T. The number of oocytes did not significantly differ between the left and right ovary for any species. The total number of mature oocytes increased with L_T for six of eight species examined. The number of oocytes for one species, B. aleutica, increased in number until 145 cm L_T, then declined in those individuals greater in length. The egg cases of all species are described, of which four (B. lindbergi, B. parmifera, B. taranetzi and B. trachura) have never been previously reported. Evidence is presented that suggest skates may be limited to as little as one and as many as 13 spawning seasons, depending on the species, and that senescence may occur in older individuals.     

Ultrastructure of the atrioventricular valve and ventricular endo- and myocardium of the tigerfish,Hydrocynus forskahlii

Osteology of four extant species of Bregmacerotidae, Bregmaceros houdei, B. bathymaster, B. japonicus, and B. macclellandi, is described for the first time. The osteological analysis enables the recognition of two groups: (1) B. houdei and B. bathymaster, and (2) B. japonicus and B. macclellandi. Considerable differences in the structure of skull, and pectoral and pelvic girdles among the species indicate the existence of at least two phyletic lines within the genus. Knowledge of the skeleton may be of great importance for the taxonomy of fossil and extant species of Bregmaceros.     

Mycorrhizal and dark septate fungal associations in shola species of Western Ghats, southern India

We analyzed mycorrhizal types and dark septate endophyte (DSE) fungal associations in a shola vegetation of Western Ghats region, southern India. Plants belonging to 29 species of 19 families were assessed for mycorrhizal type and DSE fungal association. Five mycorrhizal classes were classified based on morphological traits: arbuscular, ecto-, ectendo-, ericoid-, and orchid mycorrhizas. Arbuscular mycorrhizal (AM) association was the most predominant mycorrhizal type, occurring in 16 plant species, followed by orchid (3 species), ericoid- (2 species), and ecto- and ectendomycorrhizas (1 species each). Mycorrhizal association is reported for the first time in 19 plant species. DSE fungal association was found in six plant species. Arum- and Paris-type AM morphology was found, respectively, in 10 and 5 plant species, with intermediate type recorded in one species. In this study, some new records on the morphological types of AM in some plant families were obtained. Further occurrence of ectendomycorrhizas in Pinus oocarpa and dark septate fungal association in Eleaocarpus munronii, Symplocos cochinchiensis, Daphniphyllum neilgherrense, Euodia roxburghiana, Syzygium arnottianum, and Syzygium montanum are reported for the first time. Roots of Berberis tinctoria, Mahonia leschenaultii (Berberidaceae), Elaeagnus latifolia (Elaeagnaceae), and Elaeocarpus oblongus (Elaeocarpaceae) lacked any fungal structures.     

Structural and numerical chromosomal polymorphism in natural populations ofAlopecurus (Poaceae)

Considerable structural and numerical chromosomal variation has been found in natural populations ofAlopecurus. Interchange heterozygotes, identified by multivalent formation during meiosis, have been recovered in four out of six species studied and are reported for the first time in the diploidsA. bulbosus, andA. myosuroides, and the tetraploidA. pratensis. B chromosomes have been found in two species,A. pratensis andA. myosuroides and also in inter-specific hybrids betweenA. pratensis andA. arundinaceus. The characteristics, distribution and meiotic behaviour of both interchange heterozygotes and B chromosomes are described.     

First inventory of aphyllophoroid basidiomycetes of Zagros forests,W Iran

Zagros is a mountainous region in Western Asia, extending roughly along the western borders of Iran. Knowledge on aphyllophoroid fungi in the region is very scanty, and no survey has been made in the area. As part of an inventory of aphyllophoroids in selected protected areas in Zagros region, 32 species belonging to 6 orders, 11 families, and 25 genera are reported for the first time from Zagros. Botryobasidium robustius, Corticium endoxylon, C. erikssonii, C. lombardiae, C. meridioroseum, Eichleriella leucophaea, Phellinus rimosus, Phlebia bresadolae, and Sanghuangporus lonicerinus are newly reported from Iran. The nuclear ribosomal ITS barcode sequences are provided for 14 species (including five species sequenced for the first time), and 28S rDNA LSU sequences are given for three species. Most of the identified species belong to the orders Polyporales and Hymenochaetales.     

Diversity and ecology of algae from the Lower Jordan River,Israel

Abstract

The Lower Jordan River stretches from the outlet of Lake Kinneret till the Dead Sea and is one of the most polluted rivers in Israel. In order to estimate the aquatic ecosystem of the northern part of the Lower Jordan River we used algal communities as biological indicators in the rainy and dry seasons of 2005 and 2007. We found 152 species of algae and cyanoprokaryotes from seven taxonomic divisions, which were mostly dominated by diatoms accompanied by the greens, blue‐greens and euglenoids. The xanthophycean species Heterococcus viridis, a red freshwater alga Audouinella hermannii, and a cyanobacterium Microcrocis marina were found for the first time in Israel. In the ecological analysis we revealed groups of freshwater algae according to pH, salinity, and saprobity as well as temperature, streaming and oxygenation. Quantitative information on the relationship between species and environmental variables was obtained using CCA analysis, emphasizing the major seasonal parameters. The extent of association of species with the environmental variables vector allowed us to determine the bio‐sensors and bio‐indicators, which may be relevant for monitoring of pollutants in the Lower Jordan River. The combination of bio‐indicational methods and statistics were effective in the determination of the main factors influencing algal diversity, as well as in revealing the indicators or bio‐sensing species for the most important environmental variables.     

Parasitism of three attelabid weevils by Bracon (Uncobracon) apoderi Watanabe (Hymenoptera: Braconidae) in Kyushu,Japan

The larval parasitoid Bracon (Uncobracon) apoderi Watanabe (Hymenoptera: Braconidae) is reported from Kyushu for the first time. Two host weevils, Phymatapoderus latipennis and Paroplapoderus pardalis (Coleoptera: Attelabidae), are newly recorded. Bracon apoderi parasitized three attelabid species, including Apoderus balteatus, but did not parasitize Cycnotrachelus roelofsi even though it is a dominant attelabid species in the study site. In addition, B. apoderi mainly parasitized suspended cradles rather than cut‐off cradles.     

Diversity and distribution of Chironomidae (Insecta: Diptera) of the Oued Charef basin,North-Eastern Algeria

Summary. As part of the study of the Chironomidae fauna in lotic waters of North-Eastern Algeria, nine sampling stations in the Oued Charef basin were visited monthly during a study cycle. This work collected 7615 specimens forming a list of 75 species divided into four subfamilies. For North Africa, 23 species are reported for the first time, including six species of Tanypodinae (Paramerina vaillanti, P. berkana, Procladius lugens, Thienemannimyia zousfana, Trissopelopia longimana, Trissopelopia sp. and Zavrelimyia berberi), eight species of Chironominae (Cladotanytarsus vanderwulpi, Cryptochironomus obreptans, C. supplicans, Cryptotendipes usmaensis, Polypedilum sordens, Micropsectra fallax, M. contracta and Tanytarsus sylvaticus), and nine species of Orthocladinae (Cricotopus tibialis, Chaetocladius insolitus, C. piger, Tokunagaia rectangularis, Heterotrissocladius subpilosus, Limnophyes gurgicola, Nanocladius bicolor, Rheotanytarsus distinctissimus and Smittia sp.). In Algeria, 34 species are reported for the first time: seven Tanypodinae, 15 Chironominae and 12 Orthocladinae. In addition to the species reported as new for North Africa, the following ones can be added: Macropelopia nebulosa, Harnischia curtilamellatus, Microtendipes chloris, M. confinis, Polypedilum convictum, Stictochironomus sp., Paratanytarsus dissimilis, Cricotopus fuscus, C. trifascia and Pseudosmittia sp. This study has highlighted factors that control the distribution of the Chironomidae depending on characteristics of each site and the study season. The results have shown that the occurrence and diversity of chironomid species in these streams are significantly influenced by conductivity, temperature, current velocity and the type of substratum, while altitude had no significant effect on chironomid occurrence and distribution. The Motomura analysis and the ecological indices comparison have shown that the sampled stations are widely different. Despite the extreme environmental conditions undergone by streams of this area (eutrophication, high temperatures, drought in summer and water abstraction), Oued Chaniour was the richest and most balanced community, comprising 40 mostly stenotopic species, which require undisturbed conditions.

Non-siliceous algae in a five meter core from Lake Kinneret (Israel)

The composition and succession of non-siliceous algae, studied in a five meter core from Lake Kinneret (Israel), are described. Only Chlorophyta species were recorded, probably due to the standard palynological sample processing which was used. In the lower part of the core, from the bottom to 300 cm (interval 5500–2500 years B.P.), Botryococcus braunii was the only common alga. Relevant changes in algal diversity and abundance occur at 300 cm. Many species of green algae were recorded for the first time (Pediastrum, Scenedesmus, Coelastrum, etc.). These changes may be related to an increase in nutrient concentration as a consequence of cultural disturbance. In the interval 300-0 cm, a succession of Pediastrum species is followed. The recovered green algae are extant in the present plankton of Lake Kinneret. They also constitute an important part of the algae found in the profundal sediments today.     

Diphyllobothriids (Cestoda: Pseudophyllidea) from the long-finned pilot whale Globicephala melas (Traill, 1809) off the Faroe Islands,with comments on the taxonomy of Diphyllobothrium Cobbold, 1858 species from cetaceans

The taxonomy of marine species of the genus Diphyllobothrium, particularly those parasitic in cetaceans, is rather confused. During parasitological investigations of long-finned pilot whales Globicephala melas from waters off the Faroe Islands, five diphyllobothriid species were detected: Diphyllobothrium sp. (possibly D. polyrugosum), D. stemmacephalum, Diphyllobothrium sp. A, Diphyllobothrium sp. B and Diphyllobothriidae sp. D. stemmacephalum is reported for the first time from G. melas. The stituation regarding the taxonomy of Diphylobothrium species from cetaceans is briefly reviewed. It is concluded that the recent development of genetic techniques may be of great value in relation to clarifying the taxonomy of this group.
