total species richness of terrestrial and groundwater (vadose and phreatic)
fauna, dissecting regional diversity into alpha and beta components; (2) to
analyze the contribution of historical and ecological determinants in
shaping spatial patterns of subterranean biodiversity across the region;
and (3) to assess the conservation value of species and caves, mapping
priority areas for biodiversity conservation in the Karst.

http://dx.doi.org/10.3897/zookeys.50.504. ABS: The centipede
genus Eupolybothrus Verhoeff, 1907 in North Africa is revised. A new
cavernicolous species, E. kahfi Stoev & Akkari, sp. n., is described from a
cave in Jebel Zaghouan, northeast Tunisia. Morphologically, it is most
closely related to E. nudicornis (Gervais, 1837) from North Africa and
Southwest Europe but can be readily distinguished by the long antennae
and leg-pair 15, a conical dorso-median protuberance emerging from the
posterior part of prefemur 15, and the shape of the male first genital
sternite. Molecular sequence data from the cytochrome c oxidase I gene
(mtDNA-5' COI-barcoding fragment) exhibit 19.19% divergence between
E. kahfti and E. nudicornis, an interspecific value comparable to those
observed among four other species of Eupolybothrus which, combined
with a low intraspecific divergence (0.3-1.14%), supports the
morphological diagnosis of E. kahfi as a separate species. This is the first
troglomorphic myriapod to be found in Tunisia, and the second
troglomorph lithobiomorph centipede known from North Africa. E.
nudicornis is re-described based on abundant material from Tunisia and
its post-embryonic development, distribution and habitat preferences
recorded. E. cloudsley-thompsoni Turk, 1955, a nominal species based on
Tunisian type material, is placed in synonymy with E. nudicornis. To
comply with the latest technological developments in publishing of
biological information, the paper implements new approaches in
cybertaxonomy, including database and interactive key publishing,
georeferencing of all localities via Google Earth, and ZooBank, GenBank
and MorphBank registration of datasets. An interactive key to all valid
species of Eupolybothrus is made with DELTA software. KW:

TRONTELJ, ISBN 978-961-269-286-5. ABS: The neotropical
characid fish Astyanax, which has colonized Middle and North America
at the end of Pliocene, has gained considerable interest in evolutionary
research. It occurs in all freshwater habitats providing sufficient
temperature conditions like rivers, creeks, stagnant pools, cenotes, and
lakes. Within two restricted karst areas in Mexico it has even developed
eye and pigment reduced cave forms. The various surface populations
show considerable meristic and morphometric variation. This is probably
the reason why a large number of species and subspecies have been
described in the past. However, they were very poorly defined and their
taxonomy is still a matter of research. Molecular studies of the cave
populations showed that they have descended from multiple invasions of
surface Astyanax at different times being the cause of different
phylogenetic age. It is assumed that this is due to climatic change during
Pleistocene. It was furthermore found that genetic introgression is a
relatively frequent event in the cave populations. We performed a
molecular study using mtDNA sequences and microsatellite data of
several surface and the cave populations. Based on these markers several

different haplotype lineages and microsatellite clusters could be
discriminated. However, the clusters of the two markers were not
congruent. Furthermore, the distribution of the clusters is mostly not
correlated with geographic barriers. Such distribution pattern cannot be
explained by deep vicariant events but rather reflects random colonization
events. The taxonomic status of Mexican Astyanax populations is
discussed. http://www.icsb2010.net/

www.polytec.com. ABS: In the life of insects, vibrational signals
mediate important information that is used in various contexts, from pair
formation to detection of predators or finding prey. Therefore, insects are
equipped with both extremely sensitive receptor organs in the legs for
detection of substrate vibrations and the underlying neural network
enabling recognition and localization of the signallers in a complex
environment. Without the use of special equipment to detect those
signals, the intriguing world of insect vibrations would remain hidden to
humans, which mostly communicate by sight and sound.

ABS: Cave crickets (Rhaphidophoridae) represent an under investigated
group of Ensifera with respect to mating behaviour and communication,
since they neither hear nor emit sound. In this study we describe the
complete process of courtship and mating together with the substrateborne
vibrational signalling in the mid-European cave cricket
Troglophilus neglectus. Males produce substrate vibration signals with
abdominal oscillations during the close range courtship. As detected by
laser vibrometry, only one type of signals is produced with the mean
duration of 566 ms and repetition time of 2.2 s. Most of the signals'
spectral energy lies below 300 Hz with the dominant frequency between
80-90 Hz. At the point of measurements, 5-10 cm away from the
signaller, the peak velocity of signals ranged between 2.5*10-5 - 10-6
m/s. In the prothoracic nerve chord ganglion of T. neglectus six most
highly sensitive vibratory interneurons that were previously identified
respond to the respective range of frequencies and intensities; only one
neuron, however, conveys this information directly towards the brain. To
determine to what degree the vibrational system of T. neglectus may be
adapted to detect intraspecific signals at further processing levels, we
investigated spectral sensitivity and responses to play-backed male
signals in the brain neurons using intracellular recording. So far two
(groups of) local neurons have been identified in the lateral
protocerebrum, with broadband excitatory "on" and "off" responses and
inhibitory responses to vibration, respectively. In addition, three different
types of physiological responses have been recorded, expressing low-,
middle- and high-frequency sensitivity, respectively. Of these neurons,
only one low-frequency tuned element responded to the signals of the
male at the relevant intensity.

Caves ranks among the most important karst phenomena not only in
Slovenia's Karst region, but worldwide. Škocjan Caves is on the
UNESCO list of natural and cultural world heritage sites. It is also
featured on the Ramsar list of wetlands of international importance as the
first registered underground wetland in Europe. In this regard, a very
important task is raising visitors' awareness of the importance of
protecting endangered and protected plant and animal species. We
therefore need to properly interpret scientific data and findings, and adapt
and present this information so that it can easily be understood by the
general public. In our case, we decided to use technical illustrations to
present some of the most important species, with an emphasis on the
aboveground and subterranean karst world. So far, twenty-seven
