Article Reference First record of the rotifer Lecane shieli Segers and Sanoamuang, 1994 from Australia
The monogonont rotifer Lecane shieli is recorded for the first time from Australia (Bora Channel in the Macquarie Marshes, New South Wales: 30.65872° S/147.53 144° E). Until recently, L. shieli was known only from Thailand, where the species was first described. This Australian record of a Thai 'endemic' is interesting in considering possible dispersal and biogeographical distribution.

Article Reference Restoration of tropical peat swamp rotifer communities after perturbation: An experimental study of recovery of rotifers from the resting egg bank
In order to assess the recovery potential of tropical freshwater communities after disturbance, we performed an experimental study on the effects of exposure conditions and durations of storage on hatching of rotifer resting eggs in sediment. Well-mixed surface sediment samples from Mai Khao peat swamp on Phuket Island, Thailand, were stored under three conditions (cold -4°C & dark: CD; ambient -32-42°C & dark: AD; and ambient & daylight conditions: AL), for different periods of time (1, 2, 4, 6, 12, 18 and 24 months). The number of species hatching from the sediment was significantly affected by treatment for both short- (1-6 months) and long-term (6-20 months) exposure. Significant effects of short- and long-term exposure within treatments were also present. Both factors interacted significantly. Regarding numbers of specimens hatching, no short-term effects of differences in treatment condition were found, but increasing the duration did have an effect. Significant effects of treatment occurred after 6 months, in addition to prolonged effects of duration. Again, both factors interacted significantly. These experiments indicate that exposure time has a strong impact on the viability of resting eggs, whereas, an effect of exposure condition appears only after 6 months. So, recovery of rotifer communities from resident sediment egg banks in disturbed peat swamps can only be effectively attained when restoration occurs within a relatively short period after perturbation. © Springer 2005.

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 chemical/x-molconn-Z 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.

Article Reference Learning from ancient water management: Archaeology's role in modern-day climate change adaptations
Climate change is altering our environment and societies worldwide have to devise adaptation strategies. Water management strategies are becoming especially important. In the past, societies had to adapt in order to survive as well. Communities often practised long‐term sustainable agriculture. By understanding the ways in which ancient communities were successful at or failed in attaining social‐ecological resilience through water management archeologists can provide important information for modern communities facing similar problems. Archeology's long time perspective is very valuable. However, archeologists are confronted with a number of issues. Archeology can only study the material remains of past societies, not the living communities. Not all human activity translates into material residue and not all materials survive. Moreover, people will not demonstrate completely rational cause‐and‐effect behavior, but ideology and beliefs, which archeology can only poorly attest, will also have influenced decisions. Nevertheless, archeology can bring a unique perspective to the debate on climate change adaptation: archeology can falsify or corroborate sustainability claims, ancient water management techniques may still be a resilient mode of subsistence and ancient techniques often rely on relatively simple technology allowing for easier adoption. When transposing ancient water management techniques to modern situations it is important to involve stakeholders from an early stage, to incorporate traditional knowledge systems as much as possible and most importantly to ascertain whether physical and socio‐cultural circumstances are comparable. Archeological knowledge on ancient sustainability and water management is not a panacea for all climate related aridification, but can contribute a unique longue durée perspective.
