Aeolid opisthobranch molluscs (Glaucidae) from the Indian Ocean and the south-west Pacific

Eight aeolid opisthobranch molluscs of the subfamilies Facelininae, Favorininae, and Herviellinae are reported from Tanzanian waters, and two species from Northwestern India. New records from Queensland, Australia greatly extend the range of two species reported from Tanzania. Phidiana militaris (Alder & Hancock) and P. indica (Bergh) are shown to be distinct and a species from New Zealand, originally identified as P. militaris , is shown to be new. P. bourailli (Risbec), previously reported only from New Caledonia, is described from Tanzania, as is a new species of Phidiana. Favorinus japonicus Baba is reported from Tanzania, the first published record outside Japan, a new species of Godiva is described from Tanzania and Queensland, and three new species of Sakuraeolis are described, one from India and two from Tanzania. A new species of Herviella is described from Tanzania.

New Pennsylvanian (Moscovian) echinoderms from Xinjiang Uyghur Autonomous Region,western China

The few Pennsylvanian echinoderm faunas reported from the Paleotethys are from China, Japan, and Australia. The Japanese and Chinese faunas contain camerates that are rare in Pennsylvanian faunas worldwide.Genera of one monobathrid camerate, two disparids, five cladids, one flexible, one blastoid, and one archaeocidarid are reported from the late Moscovian uppermost part of the Qijiagou Formation or lowermost part of the Aoertu Formation in the Taoshigo Valley near Taoshuyuan Village, Xinjiang Uyghur Autonomous Region, China. They are here referred to as the Aoertu fauna, which is most closely allied with Pennsylvanian crinoids reported from a slightly older fauna from the Qijiagou Formation in the Taoshigo Valley and with faunas known from Japan and North America. Most taxa are identified to the genus level and left in open nomenclature because of poor or partial preservation. In addition, camerate ossicles and a cup of Synbathocrinus are reported from the early Moscovian part of the Sanquanzi Formation at Yamansu, southeast of the Taoshigo Valley. New taxa described are: Synbathocrinus labrus n. sp., Stellarocrinus qijiagouensis n. sp. and Metaperimestocrinus aoertuensis n. sp.

Hyperparasitism by helminths: new records of cestodes and nematodes in proteocephalid cestodes from South American siluriform fishes

Proteocephalid cestode hyperparasites are reported from numerous proteocephalids occurring in pimelodid fishes in different regions of Brazil. In addition, three specimens of a nematode hyperparasite are reported from the proteocephalid cestode Choanoscolex abscissus from the pimelodid fish Pseudoplatystoma corruscans in Brazil. Previous records of cestode and nematode hyperparasites of cestodes are listed, and the possible identities of the Brazilian records are discussed.     

Novel chemistry of invasive exotic plants

Of the many exotic plants that have become naturalized in North America, only a small proportion are pests capable of invading and dominating intact natural communities. In the present study, we tested the hypothesis that the most invasive plants are phytochemically unique in their new habitats. A comparison of exotic plant species that are highly invasive in North America with exotics that are widespread, but non-invasive revealed that the invasive plants were more likely to have potent secondary compounds that have not been reported from North American native plants. On average, the compounds found in the invasive plants were reported from fewer species, fewer genera and fewer families than those from non-invasive plants. Many of the unique phytochemicals from invasive plants have been reported to have multiple activities, including antiherbivore, antifungal, antimicrobial and allelopathic (phytotoxic) effects, which may provide the plants with several advantages in their new environments.     

Corals,molluscs, and paleogeography of late Jurassic strata of the Cerro Pozo Serna,Sonora, Mexico

Jurassic strata of late Oxfordian to early Kimmeridgian age are reported from the Cerro Pozo Serna, northwest-central Sonora, Mexico. The presence of these marine strata greatly alters previous paleogeographic reconstructions of the Tethyan embayment in this area. Approximately 60% of the Sonorian molluscan fauna has been previously reported from Jurassic horizons in the Gulf of Mexico and west Texas regions. The remainder of the molluscs have previously been reported from either the western interior United States or Canada. The Pozo Serna faunas seem to be zoogeographically transitional between communities present in the southern North American Tethyan realm and regions within the central North American Tethyan realm. Additionally, the Pozo Serna fauna greatly resembles contemporaneous communities reported from the Jurassic of Morocco. Corals from the Sonorian Jurassic prove to be, in large part, conspecific with well-known central European and Algerian reef-building species. The scleractinian Lepidophylliopsis gen. nov. and Macgeopsis sonorensis sp. nov. are described from central Sonora.     

Laboulbeniales (Ascomycota) from Bulgaria and other countries

Fifty-two species of the Laboulbeniales are reported for the first time from Bulgaria. One new species of Diphymyces, parasitic on Hexaurus schipkaensis is also described. The total number of species from Bulgaria is thus raised from 15 to 68. The first records of any of the Laboulbeniales are reported from Armenia, Eritrea, Georgia and Kazakhstan; more new records are reported also from Albania, China, Cyprus, Hungary, Italy, Mongolia, Namibia, Romania, Slovenia, Switzerland, United Kingdom and Yemen. The antheridia of Misgomyces dyschirii are described and illustrated.     

NOTES UPON A COLLECTION OF BIRDS FROM INDOCHINA

Notes are given on 22 selected forms and a list is appended of the type specimens and topotypical material in the collection. One species, Acrocephalus concinnens , is reported from Indochina for the first time and several forms are reported or confirmed for the first time for either North or Central Laos.

Late Holocene sea level indicators from twelve atolls in the central and eastern Tuamotus (Pacific Ocean)

New sea-level data for the late Holocene period are reported from twelve atolls of the Tuamotu archipelago: Faaite, Hikueru, Marokau, Hao, Amanu, Tatakoto, Pukarua, Nukutavake, Vairaatea, Tureia, Nukutipipi, and Hereheretue. The data come from coral conglomerate outcrops, coral colonies in growth position, in situ reef framework and marine notches; they give consistent results, and their ages are controlled by 29 radiocarbon datings. The Holocene MSL remained 0.8±0.2 m higher than at present, from before 4000 years BP until at least 1500 years BP, then dropped gradually to the present level. This pattern is very similar to that reported from the northwest Tuamotus, suggesting the absence of measurable differential vertical movements over a distance greater than 1300 km during the late Holocene. Effects of the 1983 cyclones on reef morphology are reported from some atolls and radiocarbon dates of some storm-generated reef blocks are given.     

中国及其邻国的石蕊科(地衣型子囊菌)
