269-286-5. ABS: The subterranean unsaturated zone of the karstic
areas is a fragmented landscape. The maze of more or less connected
voids harbors simple communities of mixed surface and subterranean
species. The hypogean crustaceans are dominant in almost all
communities of eight stations sampled monthly in a cave from
northwestern Romania. Water stable isotopes and flow rates were used to
understand the morphological organization of the subterranean habitats.
Communitiey structure, synchrony, temporal and spatial structures and
variation at different geographical levels are discussed in evolutionary
and conservation terms. http://www.icsb2010.net/

ISBN: 978-83-7051-575-1, 507 p. ABS: Spariolenus Simon,
1880 is one of the rarest genera of the spider family Sparassidae with just
few species described so far. Currently, six nominal species of the genus
are reported from Asia. Sparassids of Iran have been poorly investigated
with just three recorded species. During surveys in semiarid parts of Iran
(caves as well as river banks), three morphologically different specimens
of the genus were encountered. Results from investigations of somatical
and copulatory characters as well as analyzing CO-I sequences will be
presented as well as a discussion about the species status of the new
forms. The cave-dwelling species, Spariolenus sp. 1, are impressive giant
spiders and have leg spans up to 15 cm. The other two species were
caught from crevices in rocks near river banks. In this study, the
subfamily Heteropodinae is recorded for the first time from Iran.
Representatives of Heteropodinae are common inhabitants of subtropical
and tropical forests of Africa (Barylestis), Asia (Barylestis, Bhutaniella,
Heteropoda, Martensopoda, Pandercetes, Pseudopoda, Sinopoda,
Spariolenus) and Australia (Heteropoda, Pandercetes, Yiinthi). Occurring
of the members of Heteropodinae in the current arid and semiarid areas
suggests that the region used to be humid in former times. After
vanishing of the ancient tropical forest in the territory of the today's Iran,
the relict populations retreated into places like caves as remaining
suitable (=humid) habitats. Taxonomy and zoogeography of the current
species in relation to other species of the genus are discussed.

Biodiversity of ostracods (Ostracoda, Crustacea) in
groundwater habitats of Slovenia:138, poster presentation.
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: The
extensive sampling campaigns in the past few years in Slovenia provided
new information about distributional patterns of many groundwater
ostracod species. Many species known until now only from a single site
or the type locality showed wider geographical distributions. The
biodiversity and species composition of ostracods from different
groundwater habitats and different geographical regions is compared and
the updated checklist of recent Ostracoda is presented.

TRONTELJ, ISBN 978-961-269-286-5. ABS: The striking
features of groundwater biodiversity resulted in intensive debates about
the origin and distribution of species. The prevalence of relicts naturally
led to the idea that the great age and stability of many subterranean
habitats protected species from the vicissitudes of climate through
geological time whereas their epigean ancestors went extinct due to
extreme climatic change. This paradigm undoubtedly influenced one of
the most widely accepted models known as the "Glacial Relict" model (or
Climatic Relict Hypothesis; CRH) and its derivatives (the regression
model, the biphasic model of evolution, the two-step model and the threestep
model). In all these conceptual models, specific events such as cold
Pleistocene climate, marine regression, stream capture, and spring failure
resulted in the ablation of surface populations, thereby unequivocally
interrupting gene flow between epigean and hypogean populations. In
these models, speciation is allopatric and diversification in groundwater is
driven by extrinsic factors. In the seventies, the discovery of stygobionts
in tropical regions where closely related species were still extant led to
the proposal of an alternative model: the adaptive shift hypothesis (ASH).
This model postulates that epigean and hypogean populations
parapatrically diverge because of different selective pressures in surface
and subterranean habitats. The ASH differs fundamentally from the CRH
in that diversification in groundwater is a mostly continuous process
depending on intrinsic factors linked to ecological adaptation in
groundwater. Paleontology is the main method to evaluate diversification
and its variation over geological times. However, fossil records of
stygobionts are extremely scarce and morphological convergence is
believed to be rampant. In this context, methods based on molecular data
are promising alternatives for detecting temporal shifts in diversification
rates, thereby enabling to tease apart the contribution of the CRH and
ASH models. Using two of the most diverse genera of stygobiont, the
isopods Proasellus and the amphipods Niphargus, we tested whether the
speciation rate of stygobiotic taxa changed over time and if so, when and
how did the changes occur. This work was developed within the
framework of the DEEP and Biofresh research programs.

bioinformatic quest for phylogenetic resolution: adding
new genes to the Niphargus supermatrix:171. In: 20 th
International Conference on Subterranean Biology,

2010 Abstract Book, edited by: Ajda MOŠKRIČ and Peter
TRONTELJ, ISBN 978-961-269-286-5. ABS: The subject of
our study is the genus Niphargus Schiodte (Amphipoda: Niphargidae)
which is the largest genus of freshwater amphipods. It also represents one
of the most diversified and well-studied group of aquatic troglobionts.
Recent phylogenetic studies based on molecular (one nuclear and one
mitochondrial locus) and morphological data of approximately one-third
of all nominal Niphargus taxa revealed a number of smaller and
geographically defined clades although relationships between them
remain unsolved. In order to obtain the much needed, robust framework
for the study of more fundamental problems of evolution, adaptation and
adaptive radiation of this group we searched for novel, more informative
and robust molecular markers. We used a bioinformatic approach
combined with conventional PCR techniques. Our first step was a review
of published alternative nuclear protein-coding regions that resolved other
difficult phylogenies where standard universal markers had failed. We
selected thirty-two potential nuclear regions and tried to amplify them
using primers reported elsewhere. With genomic DNA as a template we
successfully amplified four nuclear regions (glutamyl- and prolyl- tRNA
synthetase, elongation factor 1- α, phosphoenolpyruvate carboxykinase
and glucose phosphate isomerase). We also constructed several primers
by scanning sequence databases and using bioinformatic tools and
amplified two additional nuclear regions (glyceraldehyde- 3-phosphate
dehydrogenase and arginine kinase). Using DNA sequence data of these
markers, a phylogeny of a subset of Niphargus species was constructed.
Together with two mitochondrial genes, COI and ATP synthetase subunit
β, our supermatrix currently contains approximately 5000 base pairs.
With the growing number of included gene sequences, both overall
phylogenetic resolution and individual node support are increasing. The
results of this preliminary study already show the potential of resolving
power of nuclear protein-coding genes. http://www.icsb2010.net/
