Asellus aquaticus from the Ljubljanica drainage. Two troglobiotic and<br />
troglomorphic populations are from Planina Cave (Rak Channel and<br />
Pivka Channel), whereas the surface population is from Planina Polje,<br />
adjacent to the cave. So far, ten loci have been analyzed in subterranean<br />
populations, with seven of them also yielding positive results in the<br />
surface population. The results show that all three populations are<br />
significantly differentiated from each other. Pairwise Fst estimates are<br />
highest between the surface and the Pivka Channel population (0.8) and<br />
are also high (over 0.6) between the two cave populations (0.57).<br />
Expected heterozygosity and allele diversity are very similar in both cave<br />
populations. We interpret this strong structure and the apparent lack of<br />
gene flow in spite of the tight hydrological interconnectedness of all three<br />
populations as consequence of ongoing speciation with ecological<br />
divergence. Our new results contradict the results obtained by<br />
mitochondrial DNA analysis and they seem to indicate stronger genetic<br />
isolation among parapatric populations. The results show the importance<br />
of employing different genetic markers and taking all of them into<br />
consideration. http://www.icsb<strong>2010</strong>.net/<br />

http://dx.doi.org/10.1007/s10750-010-0541-z. ABS: The<br />
notion of ecosystem health has been widely adopted in environmental<br />
policy, particularly in the management of river systems. Despite this,<br />
even a notional understanding of ecosystem health and its assessment in<br />
connected aquifer ecosystems remains elusive. In this article, we propose<br />
a definition and provide a tiered framework for the assessment of<br />
ecosystem health in groundwater. From the literature we identify general<br />
attributes of a healthy groundwater ecosystem and from these develop<br />
primary (Tier 1) indicators of health. Where Tier 1 benchmarks are<br />
exceeded or more detailed assessment is required, we discuss a range of<br />
indicators (Tier 2) that may together generate a multimetric index of<br />
groundwater health. Our case study using samples from an alluvial<br />
aquifer in north-western New South Wales, Australia, demonstrates the<br />
utility of both tiers of the framework, and the ability of the approach to<br />
separate disturbed and undisturbed sites. The process of multimetric<br />
development is simple and our Tier 2 benchmarks determined from<br />
limited data. Nevertheless, our framework will be applicable and readily<br />
adaptable to site-specific contexts. KW: Groundwater, Ecosystem health,<br />

269-286-5. ABS: Two new endemic species of subterranean<br />
freshwater amphipods, Crangonyx islandicus and Crymostygius<br />
thingvallensis were recently discovered in groundwater underneath<br />
porous lava fields in Iceland. We recently demonstrated that Crangonyx<br />
islandicus survived the repeated glaciations periods of the Ice Age in subglacial<br />
refugia. This species is widespread over the active volcanic zone<br />
and presents unique morphological and meristical features compared to<br />
other Crangonyx species and might represent a new genus. Crymostygius<br />
thingvallensis, defines a new family, is rare and has mainly been found in<br />
lake Thingvallavatn. These two species belong to the Crangonyctoidea<br />
super family, which has representatives both in North America and on the<br />
Eurasian continent. In order to understand where the species come from<br />
and to confirm their taxonomic status we have sequenced nuclear genes<br />
(18S rRNA and 28S rRNA, about 3000 bp per individual) from the two<br />
species from Iceland and from species from North- America, Europe and<br />
Asia. A comparison of the gene sequences to published sequences of<br />
other amphipod species resulted in phylogeny comprising 10 genes and a<br />
total of 21 species. On the taxonomic side, the phylogenetic analyses<br />
supports that the two species from Iceland are truly unpreviously<br />
described species. Furthermore, no species of Crangonyctoidea appeared<br />

closely related to C. thingvallensis. An early divergence from the other<br />
species of the group is observed, confirming its monotypic family status.<br />
The Crangonyx genus is polyphyletic and C. islandicus is clearly distinct<br />
from the other Crangonyx species, and may thus define a new monotypic<br />
genus. Crangonyx species from Europe appeared more closely related to<br />
the Stygobromus and Bactrurus genus than with the other Crangonyx<br />
species. These findings clearly highlight the need for a taxonomic<br />
revision of the group. On the phylogeographic side, C. islandicus is more<br />
closely related to other Crangonyx species from North America which<br />
supports the hypothesis of an ancient colonization trough groundwaters<br />
contacts between Greenland and Iceland during the early formation of the<br />
island. These two endemic species might therefore be the oldest<br />
inhabitants of Iceland. http://www.icsb<strong>2010</strong>.net/<br />

269-286-5. ABS: Two endemic groundwater arthropod crustacean<br />
species, Crangonyx islandicus and Crymostygius thingvallensis, were<br />
recently discovered at the mid-Atlantic volcanic island of Iceland. The<br />
extent of morphological differences from closest relatives, endemism, the<br />
geographic isolation of Iceland and its complete coverage by glaciers<br />
21000 years ago, suggests that these two species have survived glaciation<br />
periods in a sub-glacial refugium. Here we provide a strong support for<br />
this hypothesis by an analysis of mitochondrial genetic variation within<br />
Crangonyx islandicus. Our results show that the species is divided into<br />
several distinct monophyletic groups, found along the volcanic zone in<br />
Iceland, which have been separated by 0.5 to around 5 million years. The<br />
genetic divergence between groups reflects geographic distances between<br />
sampling sites, indicating that divergence occurred after the colonization<br />
of Iceland. The genetic patterns and the dependency of genetic variation<br />
on distances from the tectonic plate boundary and altitude, point to recent<br />
expansion from several refugia within Iceland. This presents the first<br />
genetic evidence of a multicellular organisms, as complex as crustacean<br />
amphipods, which have survived glaciations underneath an ice sheet. This<br />
survival may be explained by geothermal heat linked to volcanic<br />
activities, which may have maintained favorable habitats in fissures along<br />
the tectonic plate boundary in Iceland during glaciations<br />

<strong>2010</strong> Abstract Book, edited by: Ajda MOŠKRIČ and Peter<br />
TRONTELJ, ISBN 978-961-269-286-5. ABS: Palpigrades are<br />
primarily inhabitants of upper soil layers of tropical forests. Moreover,<br />
they occur in caves of the Northern Hemisphere where they are extremely<br />
rare. Eukoenenia spelaea (Peyerimhoff, 1902) is the only palpigrade<br />
species inhabiting the caves in the Western Carpathians (Slovakia,<br />
Hungary). Firstly it was described as Koenenia vagvoelgyi Szalay, 1956.<br />
Later, Dozsa-Farkas & Loksa (1970) made a redescription of the taxon<br />
and transferred it as subspecies to Eukoenenia austriaca. However, it<br />
clearly belongs to E. spelaeacomplex that involves five subspecies with<br />
very vague taxonomic status since descriptions were made based on few<br />
specimens only and differential characters were not properly described.<br />
The present contribution is based on the detailed morphological study of<br />
a population from the Ardovska Cave in Slovakia. Unique collection of<br />
specimens allowed to study variability in the most important characters<br />
and to evaluate critically the subspecies status of the species. SEM<br />
electron-microscopy was used to study detailed morphological structures.<br />
At present 14 caves in the Western Carpathians are known to be inhabited<br />
by Eukoenenia spelaea, 17 in Slovakia and 4 in Hungary. It is the
