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/

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

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/

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.

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
