7 fig. DOI: http://dx.doi.org/10.1127/1863-
9135/2010/0177-0081. ABS: The spatial and temporal patterns in
concentration and character of dissolved organic matter (DOM) in karst
basins in Slovenia and the United States were characterized. DOM in the
shallow aquifer, or epikarst, waters was characterized by low, stable
concentration and compounds of low aromaticity and humification. There
was strong temporal coherence in DOM character, but not concentration,
across locations within the epikarst. DOM in sinking streams, cave
streams, and resurgence springs typically had higher DOM concentration
and aromaticity. Fluorescence and parallel factor analysis of DOM
revealed that humic or fulvic-like substances in soils, surface and cave
streams, and springs were the dominant fluorophores. However, DOM
extracted from soils was chemically different from that present in the
stream and spring waters. Epikarst water contained humic-like and
protein-like DOM, and had fluorescence characteristics indicative of
microbial uptake and release of DOM in the epikarst. These data show
that there are substantial basin-scale patterns in DOM concentration and
character and that aquifer structure influences the spatial patterns of
DOM in karst groundwater. KW: Karst, cave, PARAFAC, groundwater,

2010 Abstract Book, edited by: Ajda MOŠKRIČ and Peter
TRONTELJ, ISBN 978-961-269-286-5. ABS: The influence of
abiotic and biotic interactions in shaping the present-day distribution
ranges of stygobiotic species has attracted very little attention essentially
because distributional patterns have historically been interpreted as
palaeogeographical imprints of the geographic range of putative epigean
colonizers. Only very recently have some studies attempted to model
species richness or distribution using abiotic predictors. In most
groundwater studies, however, physical variables alone left a substantial
amount of unexplained deviance. It is therefore necessary to investigate
the role of biotic interactions in the distribution patterns of groundwater
species. Proasellus cavaticus and Proasellus valdensis exhibit separate
but contiguous distributions along the western margins of the Jura and
pre-Alps mountains. The goal of this work is to determine whether these
two parapatric species exhibit the same trophic niche in nearby
groundwater systems, hence suggesting interspecific competition for food
along the parapatric boundary. We thus determined the diet of both
species in six caves located along the contact zone, using carbon and
nitrogen stable isotopes. The contribution of the different food resources
to Proasellus diet have been calculated using mixing model from their
13 C/ 12 C and 15 N/ 14 N ratios. In the six caves, P. cavaticus and P. valdensis
exhibit a similar diet, mainly constituted of bacteria attached on
sediments (> 70%), while particulate organic matter contributes with a
maximum of 30% to both species diet. This result indicates that
interspecific competition for food may be a structural factor of species
distribution in groundwater ecosystems. Laboratory experiments are
needed to test this hypothesis of competition by measuring the influence
of the interactions between P. cavaticus and P. valdensis on their trophic
efficiency. This work was developed within the framework of the DEEP
research program. http://www.icsb2010.net/

SIMON (T. P.), 2010. Status of Crayfish in Indiana. In:
Abstracts that were not submitted as manuscripts, but were
presented at the 2008 crayfish symposium, Southern
Division American Fisheries Society meeting, Wheeling,
WV. ABS: The number of crayfish inhabiting Indiana includes 23
species. Primary burrowers are represented by four species, secondary
burrowers by eight species, and tertiary burrowers by eleven species. Six
checklists have been historically compiled for crayfish within Indiana;
however, little is known about species distributions. From the period
between 1891 and 1955, only ten crayfish species were documented and
significant confusion existed in our understanding of species distribution,
identity, and biology. Most early studies (
