http://dx.doi.org/10.2134/jeq2009.0048. ABS: In the absence of<br />
sunlight energy, microbial community survival in subterranean aquifers<br />
depends on integrated mechanisms of energy and nutrient scavenging.<br />
Because karst aquifers are particularly sensitive to agricultural land use<br />
impacts due to rapid and direct hydrologic connections for pollutants to<br />
enter the groundwater, we examined the fate of an exogenous pesticide<br />
(atrazine) into such an aquifer and its impact on microbial ecosystem<br />
function. Atrazine and its degradation product deethylatrazine (DEA)<br />
were detected in a fast-flowing karst aquifer underlying atrazineimpacted<br />
agricultural land. By establishing microbial cultures with sediments from<br />
a cave conduit within this aquifer, we observed two distinct pathways of<br />
microbial atrazine degradation: (i) in cave sediments previously affected<br />
by atrazine, apparent surface-derived catabolic genes allowed the<br />
microbial communities to rapidly degrade atrazine via hydroxyatrazine,<br />
to cyanuric acid, and (ii) in low-impact sediments not previously exposed<br />
to this pesticide, atrazine was also degraded by microbial activity at a<br />
much slower rate, with DEA as the primary degradation product. In<br />
sediments from both locations, atrazine affected nitrogen cycling by<br />
altering the abundance of nitrogen dissimulatory species able to use<br />
nitrogenous compounds for energy. The sum of these effects was that the<br />
presence of atrazine altered the natural microbial processes in these cave<br />
sediments, leading to an accumulation of nitrate. Such changes in<br />
microbial ecosystem dynamics can alter the ability of DEA to serve as a<br />
proxy for atrazine contamination and can negatively affect ecosystem<br />
health and water quality in karst aquifers.<br />

ABS: Townsend's big-eared bat (Corynorhinus townsendii) is a North<br />
American bat that hibernates in caves and mines. These underground<br />
habitats also are important roost sites during fall swarming, a period<br />
during which bats undergo preparation for hibernation. During swarming<br />
bats are very active at night, rousing frequently several times a night to<br />
fly within and between roosts. During hibernation nighttime activity is<br />
suppressed so that bats rouse and move infrequently. Daytime activity is<br />
suppressed during both periods by daily torpor. Both hibernacula and<br />
swarming roosts have particular thermal requirements associated with<br />
energetic optimization. Swarming roosts tend to have a higher minimum<br />
temperature than hibernacula, facilitating efficient arousal from torpor.<br />
Both roost types have low maximum temperatures, facilitating<br />
conservation of stored body fat resources. We explored and tested<br />
preferences of C. townsendii for microclimates in these habitats. Our<br />
results confirm that C. townsendii prefers habitats that are thermally<br />
constrained such that temperatures and related microclimate variables are<br />
optimum for swarming or hibernation activities. KW: Bat, caves, habitat<br />

269-286-5. ABS: The natural monument Kalkberg, which includes the<br />
Segeberger Cave, the gypsum hill and the Small Segeberg Lake, is<br />
intensively influenced by human. If measures of protection are necessary,<br />
the Kalkberg Stadium, the show cave and the cave as a hibernating place<br />
for more than 22000 bats and the habitat for the endemic cave beetle<br />
Choleva septentrionis holsatica must be considered. During the last three<br />
years such measures of protection and the modernization of the lighting<br />
with participation of experts were planned in the underground gypsum<br />
show cave, in cave passages not open for the public, and on the<br />
overground rock faces of the hill. Most of these measures are already<br />
realised. Thus it was possible to minimize the effects of primarily planned<br />
geotechnical measures. The focus was on noninvasive techniques to<br />
assure to protect the ecosystem. http://www.icsb<strong>2010</strong>.net/<br />

ISBN: 978-83-7051-575-1, 507 p. ABS: The presentation shows<br />
the results of five years of work dedicated to the Subterranean Arachnids<br />
of the Western Italian Alps. The work, that has just been published by the<br />
Natural Museum of Torino (NW-Italy), is based on unpublished material<br />
collected by Enrico LANA and Marco ISAIA throughout an intense field<br />
work from 2005 to <strong>2010</strong>, on literature records and on the complete<br />
revision of the material cited in the previous regional catalogue of the<br />
cave-dwelling spiders of Piemonte. The work is the outcome of a fruitful<br />
collaboration of several European arachnologists, who identified different<br />
arachnid groups. A special mention to Axel L. SCHÖNHOFER<br />
(Germany) and Erhard CHRISTIAN (Austria) for their contributions on<br />
harvestmen and palpigrades, respectively. Scorpions and mites have not<br />
been considered. The exclusion of scorpions is justified by the<br />
trogloxenic life of the few species recorded in the studied area.<br />
Concerning mites, records of an extremely specialized species of<br />
Troglocheles (Prostigmata: Rhagidiidae) will be published separately.<br />
The work covers 366 subterranean cavities, most of them located in<br />
province of Cuneo (166), followed by Torino (69), Biella (38), Vercelli<br />
(30), Aosta (22), Novara (21), Verbania (15), and Alessandria (5). We<br />
present 104 species (74 spiders, 14 harvestmen, 2 palpigrades, and 14<br />
pseudoscorpions). Twelve (4 spiders, 2 palpigrades, and 6<br />
pseudoscorpions) are considered as troglobiont on the basis of obvious<br />
troglomorphy, 28 as troglophilic (20 spiders, 6 harvestmen, and 2<br />
pseudoscorpions). For each species identification aids are provided,<br />
including several illustrations of diagnostic features (original drawings),<br />
in situ photographs, maps of the hypogean localities in the Western<br />
Italian Alps, large-scale distribution and considerations from the<br />
ecological and faunistic points of view. Spiders represent the major order<br />
of arachnids recorded in the study area, with Meta menardi and Metellina<br />
merianae being the most abundant, followed by Nesticus eremita,<br />
Malthonica silvestris, Pimoa rupicola and Troglohyphantes lucifuga. The<br />
latter two are endemic to the southern and northern sectors of the Western<br />
Alps respectively. Most remarkable are the troglobiont species of the<br />
genus Troglohyphantes (T. konradi, T. pedemontanus, T. lanai) that also<br />
show, together with the troglophilic T. bornensis, T. nigraerosae and T.<br />
pluto, the most restricted distributions. Another interesting species is the<br />
troglobiont Nesticus morisii, only known from the type locality in the<br />
Maritime Alps. Meta bourneti, a troglophilic and markedly thermophilous<br />
species of Turanic-European-Mediterranean corotype, is confined, in NW<br />
Italy, to one cave in the province of Cuneo and a few caves in Susa<br />
Valley (province of Torino). Among opilionids, the most interesting taxa<br />
are Holoscotolemon oreophilum, three species of Ischyropsalis, and<br />
Leiobunum religiosum. All of these species show restricted distribution<br />
and a strong relation with subterranean habitats. Palpigrades represent the<br />
flagship of this work and of the entire arachnological fauna of the<br />
Western Italian Alps. The data presented in the book are of outstanding<br />
significance. According to current knowledge, the south-western part of<br />
the Alpine chain houses Eukoenenia bonadonai and E. strinatii. Both<br />
species belong to the spelaea/austriaca complex and show highly<br />
developed troglomorphic features. Records are from three caves in the<br />
province of Cuneo. Despite the lack of details and the difficulty in finding<br />
updated information on the Western Alpine species, the pseudoscorpion<br />
section is mainly based on literature data. Several species such as<br />
Pseudoblothrus peyerimhoffi, P. ellingseni, Chthonius italicus, C.<br />
troglophilus, and Neobisium zoiai deserve special attention for their<br />
pronounced troglomorphy and the restricted distribution. With respect to<br />
overall arachnid species richness, the most important caves are located in<br />
the Alpine districts of Alpi Marittime and Alpi Liguri (province of<br />
Cuneo) which may thus be considered as a hot-spot of biodiversity.<br />
Curiously, the most interesting assemblage is found in an artificial cave,<br />
the abandoned military bunker of Vernante (province of Cuneo), that<br />
houses 9 species of subterranean arachnids. Among these, at least 6 taxa<br />
are extremely specialized and some of them, like Troglohyphantes<br />
konradi and Nesticus morisii (for which the bunker is the locus typicus),<br />
show restricted or punctual distribution. The current state of conservation<br />
policy in the Western Italian Alps is also discussed. Nearly one third<br />
(122) of the recorded caves are situated in Protected Areas, but only in<br />
five cases the cave habitat ("8310, Caves not open to public" according to<br />
92/43 Habitat Directive) is mentioned in the official document. Despite<br />
the presence of extraordinary biocoenoses and the proximity to protected
