Organic carbon in aquatic shallow subterranean
habitats:30-31. 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: Organic carbon is likely to be an important limiting
factor in shallow subterranean habitats (SSHs). Data on dissolved organic
carbon (DOC) for interstitial, epikarst, and hypotelminorheic habitats are
reviewed. The best studied of these is the epikarst. In Organ Cave, West
Virginia (U. S. A.), DOC in epikarst drips averaged 1.10 + 0.15 mg C/L
over the course of the year. In Postojna Planina Cave System, Slovenia,
DOC in epikarst drips averaged 0.70 + 0.04 mg C/L over the course of
the year. While this is at least five times lower in concentration than
water entering the caves through sinking streams, it plays a vital role
because it is more ubiquitous in the caves and forms the basis for the
biofilm. Specific UV absorbance (SUVA) at 254 nm, an estimate of
aromatic C content and an indicator of dissolved organic matter
composition, was significantly lower in drips than in sinking streams and
cave streams. In studies of the Rhône and its tributaries, Marmonier et al.
report DOC values averaging between 1.9 and 3.5 mg C/L. Lower values
were reported for smaller streams, increased depth, and increased lateral
distance from the river. For the first time, we report on values for
hypotelminorheic habitats, which average 3 mg C/L.

Aquatic subterranean species are often geographically and numerically
scarce. Many of these species are denizens of epikarst, the uppermost
zone of karst with semi-isolated solutional openings and channels, and
are only known from drip pools in caves where they accumulate as a
result of animals dripping out of the epikarst. 2. The question of whether
these pool communities adequately reflected the epikarst community was
addressed by directly collecting animals from drips in a continuous
collecting device. 3. The study area was six caves in Slovenia, where a
total of 35 drips and associated pools were sampled for copepods for a
period of approximately one year. A total of 37 copepod species were
found, 25 of them stygobionts and 16 epikarst specialists. 4. Overall, the
frequency of stygobionts was 1.5 times higher in drips compared with
pools and the frequency of epikarst specialists was three times higher in
drips compared with pools, and the frequency of immature individuals
was higher in drips compared with pools, with the exception of one
artificially enlarged pool in Škocjanske jame. The cause of this difference
is probably increased juvenile mortality in pools and reduced
reproduction, indicating that pools are not source populations. 5. The
results of this research suggest that epikarst per se, not just the sampling
sites (including pools) in caves, needs to be the focus of conservation
planning. KW: Cave fauna, Copepoda, epikarst, rare species, stygobionts.

Background: Local adaptation to divergent environmental conditions can
promote population genetic differentiation even in the absence of
geographic barriers and hence, lead to speciation. Perturbations by
catastrophic events, however, can distort such parapatric ecological
speciation processes. Here, we asked whether an exceptionally strong
flood led to homogenization of gene pools among locally adapted
populations of the Atlantic molly (Poecilia mexicana, Poeciliidae) in the
Cueva del Azufre system in southern Mexico, where two strong

environmental selection factors (darkness within caves and/or presence of
toxic H2S in sulfidic springs) drive the diversification of P. mexicana.
Nine nuclear microsatellites as well as heritable female life history traits
(both as a proxy for quantitative genetics and for trait divergence) were
used as markers to compare genetic differentiation, genetic diversity, and
especially population mixing (immigration and emigration) before and
after the flood. Results: Habitat type (i. e., non-sulfidic surface, sulfidic
surface, or sulfidic cave), but not geographic distance was the major
predictor of genetic differentiation. Before and after the flood, each
habitat type harbored a genetically distinct population. Only a weak
signal of individual dislocation among ecologically divergent habitat
types was uncovered (with the exception of slightly increased dislocation
from the Cueva del Azufre into the sulfidic creek, El Azufre). By
contrast, several lines of evidence are indicative of increased floodinduced
dislocation within the same habitat type, e. g., between different
cave chambers of the Cueva del Azufre. Conclusions: The virtual absence
of individual dislocation among ecologically different habitat types
indicates strong natural selection against migrants. Thus, our current
study exemplifies that ecological speciation in this and other systems, in
which extreme environmental factors drive speciation, may be little
affected by temporary perturbations, as adaptations to physico-chemical
stressors may directly affect the survival probability in divergent habitat
types.

2010 Abstract Book, edited by: Ajda MOŠKRIČ and Peter
TRONTELJ, ISBN 978-961-269-286-5. ABS: Past attempts to
understand the evolution and establish a phylogenetic system of the
Leptodirini (Leiodidae, Cholevinae) were based on morphological
characters. None of these attempts could satisfactorily explain the
resulting morphological and biogeographical patterns. Most authors
concluded that modern molecular approaches are the only possible and
legible way to solve the enigmatic Leptodirine phylogeny in the future. In
the last years, we conducted a molecular phylogenetic study of 54
different genera of Leptodirini. We sequenced about 3.3 kbp from two
mitochondrial (COI and 16S) and three nuclear gene segments (two
pieces of 28S rDNA, Histone H3), and analyzed them using standard
phylogenetic procedures. External and internal morphological characters
used so far in the higher suprageneric classifications of leptodirines were
cladisticly analyzed in combination with molecular data. Phylogenetic
trees from different loci recovered a monophyletic origin of the studied
leptodirines. Our results and those recently obtained by other authors
suggest that most subterranean Leptodirini are geographically grouped.
The most important and consistent result of the molecular phylogenetic
reconstruction was the resolution of major lineages differing significantly
from those recognized at present based on morphological characters only.
The traditional suprageneric subdivision of leptodirines into
Antroherponini (Antroherpona) and Bathysciini (Bathysciae) as well as
subtribes Anthroherponina, Spelaeobatina, Bathysciina, Bathysciotina,
Leptodirina and Pholeuonina are polyphyletic groups and have to be
redefined or rejected. Since not all of the genera or genera-groups were
molecularly tested, a more precise new systematics of the Leptodirini is
not yet possible. http://www.icsb2010.net/
