These three climate change factors will, separately and in combination, affect the biotic and abiotic components of the soil ecosystems. Enchytraeids are an important component in soil ecosystems and affect the decomposition processes and the nutrient mineralisation both directly and indirectly by their activity. The background for this thesis was to investigate the effect of climate change on fi eld popula- tions of enchytraeids dominated by the species Cognettia sphagnetorum. Although enchytraeids are extremely sensitive to long-term desiccation stress, they also have a high degree of resilience when optimal conditions return. Field populations of enchytraeids were exposed in a full factorial in-situ ex- periment to increased CO2, temperature and prolonged drought manipulation for three years. In the short term, enchytraeids appear to be unaffected by climate change when all factors were combined. The negative impact of drought was counteracted when CO2 was present, as drought and CO2 in combination acted additively during summertime. However, in a long-term drought experiment in which C. sphagnetorum was exposed repeatedly to drought during a six year period, the species was, evidently, negatively affected. Even though the enchytraeids had been exposed for a long period, there was no sign of increased drought resistance.

All of the work has been conducted at the Department of Terrestrial Ecology at National Environmental Research Institute (NERI), Aarhus University, in Silkeborg, Denmark, dur- ing the past four years. The PhD is apart of the Danish climate change experiment “CLI- MAITE”, which was initiated in 2005. The objective of this PhD was to examine the effect of climate change on enchytraeids both in the fi eld, but also in the laboratory. The introduction of the thesis has the structure of a review paper on the effect of climatic changes on terrestrial enchytraeids. Following the intro- duction are six papers, all concerning the effects of increased climatic stress, with a special focus on drought stress. Four of the papers have been published, one has been submitted, and one is ready for submission. This thesis was fi nanced by the project CLIMAITE (CLIMAte change effects on biological processes In Terrestrial Ecosystems; www.climaite.dk) funded by the The Villum Kann Rasmussen Foundation. I would like to thank several people, who have all contributed to making this PhD possible. First of all, I would like to thank my supervisor Martin Holmstrup at NERI, who has been of great support, inspiration and always has taken the time to talk to me. My internal supervisor Søren Christensen from University of Copenhagen, for always helping when needed. To the people behind the CLIMAITE project, which made it all possible and for some inspiring and pleasant meetings – I am going to miss them! Thank you for introducing me to terrestrial ecol- ogy and special thanks goes to the CLIMAITE PhD group, which has been of great help and a lot of fun. I also owe a large thank you to a range of enchytraeid people, a special thanks goes to Bent Christensen and his wife, who introduced me to the taxonomy of the enchytraeids, to Dr. Valerie Standen, University of Durham, UK for helping collect soil at Moor House, to Dr. Maria Briones and Noela, University of Vigo – thanks to all of you for your help, inspiration and hospitality. Finally, I would like to acknowledge Philip Vernon from the University of Rennes in France for his help during my stay in France and Rudiger Schmelz and Louise Illum Sørensen for collecting soil in Spain and Finland. Thank you, to all my colleagues at NERI in Silkeborg. In particular, I wish to thank Paul Henning Krogh, Zdenek Gavor, Elin Jørgensen, Mette Thomson, John Rytter, Lene Birksø, Charlotte Elisabeth Kler, Ninna Skafsgaard, Frankie Henriksen, Lars Henrik Heckman, Helle Weber Ravn and several others for technical assistance, sparring and a lot of fun. A very special thank goes to my fellow PhD students, Anne Mette Bindesbøl, Stine Slotsbo and Dorthe Jensen for sparring, critical review of this thesis, and lots of good times. Tinna Christensen has been very helpful with graphical assistance, Rebekka Andreasen has been very kind to help with the Danish abstract and Lisbeth Jeppesen are thanked for her correction of the language. Without help and support from friends and family, this thesis would have been an up-hill battle. Finally, I am deeply indebted to Jens, Emma and Anders for always being there and for taking your time to hear about the life of “white earthworms”.

E-mail: [email protected] Abstract This study describes the fauna of the marine enchytraeid genus Grania at two locations on the Australian Great Barrier Reef: Lizard and Heron Islands. Collections were made from 1979 to 2006, yielding four new species: Grania breviductus sp. n., Grania regina sp. n., Grania homochaeta sp. n. and Grania colorata sp. n.. A re-description of Grania trichaeta Jamieson, 1977 based on new material is also included, along with notes and amendments on G. hyperoadenia Coates, 1990 and G. integra Coates & Stacey, 1997, the two latter being recorded for the first time from eastern Australia. COI barcode sequences were obtained from G. trichaeta and G. colorata and deposited with information on voucher specimens in the Barcode of Life database and GenBank; the mean intraspecific variation is 1.66 % in both species, while the mean interspecific divergence is 25.54 %. There seem to be two phylogeographic elements represented in the Great Barrier Grania fauna; one tropical with phylogenetic affinities to species found in New Caledonia and Hong Kong, and one southern (manifested at the more southerly located Heron Island) with affinities to species found in Southern Australia, Tasmania and Antarctica.

Shain, [email protected] Received 7 April 2009; Accepted 22 May 2009 Recommended by Dan Graur Glacier ice worms, Mesenchytraeus solifugus and related species, are the largest glacially obligate metazoans. As one component of cold temperature adaptation, ice worms maintain atypically high energy levels in an apparent mechanism to offset cold temperature-induced lethargy and death. To explore this observation at a mechanistic level, we considered the putative contribution of 5 adenosine monophosphate deaminase (AMPD), a key regulator of energy metabolism in eukaryotes. We cloned cDNAs encoding ice worm AMPD, generating a fragment encoding 543 amino acids that included a short N-terminal region and complete C-terminal catalytic domain. The predicted ice worm AMPD amino acid sequence displayed conservation with homologues from other mesophilic eukaryotes with notable exceptions. In particular, an ice worm-specific K188E substitution proximal to the AMP binding site likely alters the architecture of the active site and negatively affects the enzyme’s activity. Paradoxically, this would contribute to elevated intracellular ATP levels, which appears to be a signature of cold adapted taxa.

    HISTORIA Y PRESENTE DE LAS COLECCIONES DE INVERTEBRADOS DEL MUSEO NACIONAL DE CIENCIAS NATURALES (CSIC) Miguel Villena Sánchez-Valero Conservador de las colecciones de Invertebrados 1 .- RESEÑA HISTÓRICA Para encontrar el origen de la Colección de Invertebrados de Museo Nacional de Ciencias Naturales de Madrid tenemos que remontarnos al último tercio del siglo XVIII, cuando, tras numerosas gestiones y diversos intentos, una Real Orden de Carlos III, promulgada el 17 de octubre de 1771, crea el Real Gabinete de Historia Natural y pone punto final a las enormes carencias que, en ese sentido, tenía España respecto a otros países europeos. En estos momentos iniciales, y hasta que se inaugure de forma definitiva el 4 de noviembre de 1776, las colecciones custodiadas en este establecimiento tendrán como base el excelente Gabinete de Historia Natural formado en París por el sabio ilustrado Pedro Franco Dávila, quien, gracias a sus desvelos en la formación del Gabinete y, sobre todo, gracias a los conocimientos en Historia Natural, adquiridos en una estancia de casi 26 años en París, en contacto con los científicos más reputados del momento, será nombrado Primer Director del establecimiento. Con este nombramiento Don Pedro recibió un triple encargo: que se coloquen en Madrid en debida forma las preciosidades actuales del Gabinete, y las demás con que el Rey providenciará enriquecerle, que se verifique la instrucción pública y, sobre todo, el encargo especial de que le tenga a su cuidado y procure difundir el gusto y nociones de tan importante materia.1 A partir de ese momento el interés principal del Gabinete recién creado y de sus dirigentes será el incremento de las colecciones con ese, cuando menos, triple objetivo que tiene que tener todo Museo2 que se precie de tal, es decir: • Conservar, catalogar, restaurar y exhibir de forma ordenada sus colecciones.

Its purpose is to establish consistent levels of taxonomic resolution among agency, academic and other biologists. The information in this SOP has been established by researching current taxonomic literature. It should assist an experienced aquatic biologist to identify organisms from aquatic surveys to a consistent and reliable level. The criteria used to set the level of taxonomy beyond the genus level are the systematic treatment of the genus by a professional taxonomist and the availability of a published key. 1.2 The consistency in macroinvertebrate identification allowed by this document is important regardless of whether one person is conducting an aquatic survey over a period of time or multiple investigators wish to compare results. It is especially important to provide guidance on the level of taxonomic identification when calculating metrics that depend upon the number of taxa.

In their appeal to the Commission, Schmelz et al. (BZN 72: 186–192) give a good repetition of the taxonomical history of the taxa involved (detailed by us in Rota et al., 2008; Martinsson et al., 2014, 2015). However, we would like to highlight a few additional points. 1. The case in question (our invalidation of Cognettia in favour of Chamaedrilus and Euenchytraeus) arose after two of us (Martinsson & Erséus, 2014) provided molecular evidence that Cognettia sphagnetorum (Vejdovský, 1878) in its commonly accepted definition, based on Nielsen & Christensen’s (1959) revisionary work, is a non-monophyletic complex of species.

This work presents the first overview of groundwater oligochaete assemblages of the Mercantour National Park after a standardized exploration of both consolidated (fractured massif) and unconsolidated (porous) aquifers. About 40 species of oligochaetes were found at 49 stations representative of the main hydrogeological basins of the Mercantour National Park, from both spring and hyporheic zone habitats.
