Article Reference New metallothionein mRNAs in Gobio gobio reveal at least three gene duplication events in cyprinid metallothionein evolution
This paper reports the identification and analysis of the primary structure of three novel metallothionein cDNA sequences in the gudgeon, Gobio gobio (Cyprinidae). Two different 180 bp coding regions were identified, resulting in two MT isoforms differing in one amino acid. The primary structure of the amino acid sequence was compared to other cyprinid MT sequences. Furthermore, two differently sized cDNAs were discovered in one of the two transcripts. We present a phylogenetic comparison of our sequences to other, previously published cyprinid MT gene sequences. Our analysis reveals an unexpected complexity in cyprinid MT evolution, with at least three gene duplication events. Differences and homologies between the evolution of cyprinid MT genes are compared to other teleost families. Finally, possible implications for metallothionein classification are discussed. © 2005 Elsevier Inc. All rights reserved.

Article Reference Paracrenhydrosoma oceaniae sp. nov. (Copepoda: Harpacticoida), from Kongsfjorden, Northwest Svalbard (Arctic)
Both sexes of a new species of Cletodidae belonging to the Acrenhydrosoma-lineage are described from material collected at Kongsfjorden (Svalbard) and attributed to the genus Paracrenhydrosoma Gee, 1999. Paracrenhydrosoma oceaniae sp. nov. is easily distinguished from its congeners by the reduced setal formula of the natatorial legs, lacking the inner subdistal seta on segment 3 of legs 3 and 4. Several other characteristics viz. antennular and antennal armature, and the free leg 5 exopodite in both sexes, are indications of its basal position in the genus.

Article Reference Rotifers from Kalasin Province, Northeast Thailand, with notes on new and rare species
We report on a survey of rotifers from 30 habitats in Kalasin Province, Northeast Thailand, collected during Dec. 2001. One hundred and fifty species were identified. One of them, Lecane lungae sp. nov. is new to science, and two, L. opias (Harring and Myers), and L. stichoclysta Segers are new to the Oriental region and Thailand; the record of L. stichoclysta is the second record ever of the species after its description from Nigeria (Africa). In addition, we illustrate a remarkable morphological variant of Keratella cochlearis. These records, together with the new occurrences of other endemic rotifer species illustrate the remarkable diversity of the Thai rotifer fauna, and add to our knowledge of rotifer chorology.

Article Reference Tale of a sleeping beauty: A new and easily cultured model organism for experimental studies on bdelloid rotifers
We present the description of a new species of bdelloid rotifer, Adineta ricciae n. sp., which emerged from dry mud of Ryan's billabong, Victoria, Australia. Its conspicuous frontal eyes easily diagnose the species; it differs from A. oculata (Milne) by the position of the eyes and its general habitus. The animal came to our attention because it is exceptionally easy to culture, so that the species already is being used in diverse experimental studies utilising bdelloid rotifers as model organisms. © Springer 2005.

Inproceedings Reference Stratigraphic context and dating of the Middle and Late Eocene vertebrate localities of the Fayum.
The Fayum Oasis and surrounding areas in Egypt include a number of exceptionally rich and important fossil vertebrate sites. These include the Wadi Al-Hitan World Heritage Site, made famous by the abundance of archaeocete whale remains, and the site BQ-2 with its diverse terrestrial mammals, including primates. Despite the importance of this area, the stratigrapby is poorly understood and there has be little agreement in the dating of the fossiliferous units. This is in large part due to the extreme diachroneity of some of the rock units and paucity of biostratigraphically useful fossils within the shallow water facies. Platform carbonates are overlain by condensed open marine mudstones of the Gebannam Formation. These span the Bartonian-Priabonian boundary, with a diverse offhore marine fauna being present throughout, including marine mammals. Four units of shoreface sandstone of the Birkel Qarun Formation overlie and partly pass into the Gehannam Formation. The lowest of these sandstone units is dated to nannofossil zone NP19/20, and hence 'mid' Priabonian, and contains the oldest archaeocetes described from the region. Diverse fossils, including abundant whales, are present throughout the Birket Qarun Formation, but these are especially concentrated at the top of the lowest sandstone (lowstand systems tract) and in the transgressive lower part of the third sandstone and its lateral equivalent within the Gehannam Formation (transgressive systems tract). The overlying Qasr el Sagha Formation is a very rapidly deposited deltaic/lagoonal complex. Tidal channels from two to over 40 metres deep are present throughout. The lower part of this formation is still in nannofossil zone NP19/20. INterchannel deposits contain a fully marine, but probably shallow water, assemblage. Larger channels also include deeper water elements near the base, with transported terrestrial and quasimarine elements being present within the uppermost part of a small channel fill at quarry BQ-2. The transition to the non-marine units above is sharp but conformable and coincides with the base of the Oligocene. The clastic succession indicates the initiation of Nile-type drainage and coincides with the uplift of East Africa, preventing drainage to the east. It is likely that clastic successions in the Qattara Depression and Libya can be related to the same sedimentological episodes. This is largely based on, and dedicated to, the work of Chris King, who passed away earlier this year.
