Annelid diversity in anchialine systems: unique adaptations and functional morphology of Protodrilus n. sp. to the cave environment of La Corona lava tube (Canary Islands, Lanzarote):76. In: 20 th International Conference on Subterranean Biology, Postojna, Slovenia, 29 August-3 September 2010, ICSB 2010 Abstract Book, edited by: Ajda MOŠKRIČ and Peter TRONTELJ, ISBN 978-961-269-286-5. ABS: After crustaceans, annelids are the second most diverse animal group in anchialine caves. Despite little attention paid to this group in early studies, the evidences of its high diversity has been recorded from several anchialine environments during the last 20 years, especially regarding interstitial species. Many of these records correspond to offshore forms inhabiting offshore habitats resembling caves, but stygobiotic species have also been described. Although all endemic, these stygobiotic taxa show in fact very diverse morphological adaptations. They range from typical interstitial species, morphologically similar to their offshore relatives, to highly modified meiofauna taxa with unique adaptation to drifting life style in the still anchialine water column at the caves. This holds also for several animals belonging to otherwise predominantly interstitial annelid families, such as Nerillidae and Protodrilidae. We here explore the unique functional morphology of Protodrilus n sp., an endemic species from La Corona lava tube (Lanzarote, Canary Islands). Musculature, nervous system, adhesive glands and ciliation were investigated by immunostaining and CLSM, SEM, TEM and LM. Motility, feeding activity and behavior are described from in situ and laboratory observations on live specimens (including video recording). These observations are compared to similar studies conducted in other species of the genus from coastal interstitial habitats with adaptations to the turbulent upper zone of the seafloor. The habitat of each species was characterized by measuring organic matter content, chlorophyll, salinity and sediment structure. Other cave species of interstitial annelids were compared to Protodrilus n. sp., emphasizing adaptive convergences among different lineages. These convergences are discussed in terms of the habitat of the species and compared to offshore relatives, in order to test the applicability of the current concept of troglomorphisms in Annelida. The role of historical and ecological processes on the origin of these taxa is briefly discussed. http://www.icsb2010.net/ MARTÍNEZ SÁNCHEZ-DEHESA (J.) & ZARAGOZA (J. A.), 2010.

Annelida, an often neglected component of groundwater ecosystems:77. In: 20 th International Conference on Subterranean Biology, Postojna, Slovenia, 29 August-3 September 2010, ICSB 2010 Abstract Book, edited by: Ajda MOŠKRIČ and Peter TRONTELJ, ISBN 978-961- 269-286-5. ABS: About 350 species and 100 genera represent the presently known contribution of the annelids to the groundwater fauna. Stygobionts account for about 1/3 of these species. The bulk of groundwater annelids are oligochaetes, and only a few hirudineans and polychaetes are found. Despite their frequency and richness, annelids are often ignored in the studies of groundwater diversity. This is partly due to their size, often quite small - so that they might be overlooked in the researches, and partly to the fact that their identification is difficult. We present a synthesis of the current state of knowledge about annelids, on their diversity, patchwork of endemicity and regional differences, and we underline their contribution to the diversity of the subterranean aquatic fauna. In the last decade, investigations of the groundwater fauna led to the discovery of a fauna with characteristic elements (such as the naidides of marine lineage and the stygobiont family Parvidrilidae), and of freshwater taxa showing an adaptive radiation in subterranean Bernard LEBRETON & Jean-Pierre BESSON Créé le : 01.01.2010 Modifié le : 30.06.2010 environments (such as Rhyacodrilus and Trichodrilus), or relicts of an ancient fauna (such as Rhyacodriloides). Extensive studies like the European PASCALIS Project allowed to prove the high species richness of subterranean annelid fauna of some European regions (namely Italy and Spain) and to examine the environmental gradients driving the distribution patterns of stygobiotic annelid assemblages. Habitat structure, water chemistry, anthropogenic pressure and historical factors are shown to influence the biodiversity patterns. In annelids, adaptations to the subterranean environments can be attempted by several different mechanisms, such as the body size reduction, the shifting or the asymmetrical bending of some genital organs, or the cyst formation in order to survive to habitat constraints. http://www.icsb2010.net/ MARTÍNKOVÁ (N.), BAČKOR (P.), BARTONIČKA (T.), BLAŽKOVÁ (P.), ČERVENÝ (J.), FALTEISEK (L.), GAISLER (J.), HANZAL (V.), HORÁČEK (D.), HUBÁLEK (Z.), JAHELKOVÁ (H.), KOLAŘÍK (M.), KORYTÁR (ĽU.), KUBÁTOVÁ (A.), LEHOTSKÁ (B.), LEHOTSKÝ (R.), LUČAN (R.

Increasing Incidence of Geomyces destructans Fungus in Bats from the Czech Republic and Slovakia. PLoS ONE 5(11):e13853. DOI: http://dx.doi.org/10.1371/journal.pone.0013853. ABS: Background: White-nose syndrome is a disease of hibernating insectivorous bats associated with the fungus Geomyces destructans. It first appeared in North America in 2006, where over a million bats died since then. In Europe, G. destructans was first identified in France in 2009. Its distribution, infection dynamics, and effects on hibernating bats in Europe are largely unknown. Methodology/Principal Findings: We screened hibernacula in the Czech Republic and Slovakia for the presence of the fungus during the winter seasons of 2008/2009 and 2009/2010. In winter 2009/2010, we found infected bats in 76 out of 98 surveyed sites, in which the majority had been previously negative. A photographic record of over 6000 hibernating bats, taken since 1994, revealed bats with fungal growths since 1995; however, the incidence of such bats increased in Myotis myotis from 2% in 2007 to 14% by 2010. Microscopic, cultivation and molecular genetic evaluations confirmed the identity of the recently sampled fungus as G. destructans, and demonstrated its continuous distribution in the studied area. At the end of the hibernation season we recorded pathologic changes in the skin of the affected bats, from which the fungus was isolated. We registered no mass mortality caused by the fungus, and the recorded population decline in the last two years of the most affected species, M. myotis, is within the population trend prediction interval. Conclusions/Significance: G. destructans was found to be widespread in the Czech Republic and Slovakia, with an epizootic incidence in bats during the most recent years. Further development of the situation urgently requires a detailed pan-European monitoring scheme. MARTINSEN (L.), JOHNSEN (A.), VENANZETTI (F.) & BACHMANN (L.), 2010. Phylogenetic footprinting of non-coding RNA: hammerhead ribozyme sequences in a satellite DNA family of Dolichopoda cave crickets (Orthoptera, Rhaphidophoridae). BMC Evolutionary Biology 10:3. DOI: http://dx.doi.org/10.1186/1471-2148- 10-3. http://www.biomedcentral.com/1471-2148/10/3. ABS: Background: The great variety in sequence, length, complexity, and abundance of satellite DNA has made it difficult to ascribe any function to this genome component. Recent studies have shown that satellite DNA can be transcribed and be involved in regulation of chromatin structure and gene expression. Some satellite DNAs, such as the pDo500 sequence family in Dolichopoda cave crickets, have a catalytic hammerhead (HH) ribozyme structure and activity embedded within each repeat. Results: We assessed the phylogenetic footprints of the HH ribozyme within the pDo500 sequences from 38 different populations representing 12 species of Dolichopoda. The HH region was significantly more conserved than the non-hammerhead (NHH) region of the pDo500 repeat. In addition, stems were more conserved than loops. In stems, several compensatory mutations were detected that maintain base pairing. The core region of the HH ribozyme was affected by very few nucleotide substitutions and the cleavage position was altered only once among 198 sequences. RNA
© Biospeologica Bibliographia Publications 2010-1 Page 67 sur 116 folding of the HH sequences revealed that a potentially active HH ribozyme can be found in most of the Dolichopoda populations and species. Conclusions: The phylogenetic footprints suggest that the HH region of the pDo500 sequence family is selected for function in Dolichopoda cave crickets. However, the functional role of HH ribozymes in eukaryotic organisms is unclear. The possible functions have been related to trans cleavage of an RNA target by a ribonucleoprotein and regulation of gene expression. Whether the HH ribozyme in Dolichopoda is involved in similar functions remains to be investigated. Future studies need to demonstrate how the observed nucleotide changes and evolutionary constraint have affected the catalytic efficiency of the hammerhead. MATHESON (A. L.), CAMPBELL (K.

Development of vocalization and social communication in a free-ranging nursing colony of Hipposideros turpis:223-224. In: 15 th International Bat Research Conference, Prague, 22-27 August 2010, the conference manual: Programme, abstracts, list of participants, edited by: Ivan HORÁČEK and Petr BENDA, ISBN 978-80-87154-46-5, 380 p. ABS: Hipposideros turpis is the only hipposiderid bat native to Japan. A longterm mark-recapture study in a nursing colony of this species has been conducted since 1983 on Iriomotejima Island, Okinawa Prefecture, Japan. There is great individual variation in the vocal signature of the attractive calls of new-born infants, which consist of one- or two-note syllables. The fundamental frequency of each note ranges 15~20 kHz and consists of 4 harmonic components with a maximum frequency of up to 80 kHz. Each infant repetitively emits its attractive call and, during growth, the fundamental frequency of each call increases, especially at the second note of two-note call of the Frequency Modulation (FM) type. Every night after foraging, the mother comes home and collects her own infant which has been left on the ceiling of the cave. Before the reunion for nursing, the mother touches the infant making it bark; this confirms by voice wheather it is her own baby. At each reunion, the infant emits attractive calls and the mother emits intensive echolocation type calls. By the age of three weeks, infants developed to emit pure-tone type calls of 75~77 kHz, but the fundamental harmonic, which is a feature of the immature type of call, remains. The social call of adults recorded in the nursing roost are mostly warning calls, which consist of a series of graded signals reflecting different degree of warriness. Clear differences were found in vocal character of these calls; (1) a harsh bark of low frequency( 8~24 kHz) appears to be an urgent warning; (2) an FM type of call of long duration appeared to denote the need for caution; and (3) a rhythmic FM type call (trill or chirrup) appeared to denote a middle range of warning. These finding demonstrate that the vocal activity of this species is high and that vocalization is closely related to different phases of social contexts.

In: 20 th International Conference on Subterranean Biology, Postojna, Slovenia, 29 August-3 September 2010, ICSB 2010 Abstract Book, edited by: Ajda MOŠKRIČ and Peter TRONTELJ, ISBN 978-961-269-286-5. ABS: New groundwater ecology studies are underway in the UK to sample the many geologies and areas in which the groundwater ecology is largely unknown. More detailed studies are also being carried out to investigate the local geological and hydrogeological controls on the distribution of groundwater fauna. One area of focus is the English Chalk. Stygobites have been known in Chalk groundwaters from sporadic records for more than 150 years, but there have been no systematic investigations of their distribution, and the spatial variability of stygobites in the English Chalk is largely unknown. New studies have been carried out in recent years in the Chalk of Southern England. In Berkshire 19 boreholes in two catchments (total ~400 km 2 ) were sampled at maximum and minimum water level conditions. The hydrogeology of these boreholes is well known (the detailed chalk stratigraphy, the location of inflowing fractures to the boreholes, whether the boreholes Bernard LEBRETON & Jean-Pierre BESSON Créé le : 01.01.2010 Modifié le : 30.06.2010 contain upward or downward vertical flow, and the nature and size of the voids through which the water flows from borehole imaging data). The boreholes are in a range of topographical situations (valley and interfluve) with variable depths to the water table, and they are at varying distances from surface karst features. Results from these boreholes are used to investigate whether there are local geological and hydrogeological controls on the distribution of groundwater fauna, and whether there are variations between low and high water table sampling. In addition sampling at different depths in the boreholes was carried out to investigate whether stygobionts live on the bottom or in the water column. Results from the Berkshire study are compared to those from other areas to investigate any regional differences in groundwater fauna in the Chalk. http://www.icsb2010.net/ McCRACKEN (G. F.)

ABS: The mixture of soil, epikarstic and hypogean fauna, as inputs and outputs of the vadose zone offers the possibility to understand the complex structure of this heterogeneous ecosystem, by studying the structure of its populations from two different habitats: fissures network and pools. Relationships between the copepod assemblages and the habitat characteristics from the vadose zone in caves from the Pădurea Craiului Mountains (northwestern Romania) are emphasized based on nine environmental parameters. The aims of the present research are to: 1. identify the dissimilarities between copepod communities from the vadose zone within and between caves and in the two different habitats: voids and pools; 2. depict spatial and temporal trends in heterogeneous copepod distribution in drips and pools along a vertical gradient in the vadose zone, in relationship to the environmental features at small spatial scale. Canonical Correspondence Analysis was used to explore the relationship between the copepod species and the environmental features. Vegetation cover was the most important factor influencing copepod diversity and abundance. Precipitation and the amount of drips were related to epigean species, while the electrical conductivity seemed to be related indirectly to hypogean species. Pools on limestone harbored a more diverse and abundant fauna than those on clay; the hypogean species prefer mainly the pools on limestone. Genetic analyses are in progress, extraction and PCR protocols are optimized for harpacticoid populations. http://www.icsb2010.net/ MERRITT (D. J.) & CLARKE (A. K.), 2010.
