December):35-40. ABS: Mark-recapture studies of Orconectes (O.)<br />
australis, O. (O.) sheltae, and Cambarus (A.) jonesi, conducted in Shelta<br />
Cave, Huntsville, Alabama, USA, between 1968 and 1973, provided<br />
baseline data on population sizes of all three species. Individuals were<br />
given a painted carapace mark to identify intermolts, and all were injected<br />
between the cuticle and the muscles of the abdomen with a permanent<br />
mark of Bates inks. A grand total of 1314 individual crayfish was<br />
processed during that period, and there were 1213 recaptures (92.3%) of<br />
previously marked individuals. The number of O. (O.) australis marked<br />
was 959, the number of C. (A.) jonesi was 266, and the number of O. (O.)<br />
sheltae was 89. KW: Cave crayfishes, Cambarus, Orconectes, population<br />

BENDA, ISBN 978-80-87154-46-5, 380 p. ABS: In this study,<br />
the community composition, species richness, and abundance of cavedwelling<br />
bat fauna of Yildiz Mountains is presented and our census data<br />
(2009) is compared with the results of the 2001 census to examine<br />
possible changes in populations' abundance and structure over the last<br />
few years. Approximately 42000 bats, representing nine species, were<br />
recorded in 22 caves and Miniopterus schreibersii was the most abundant<br />
species, followed by Rhinolophus ferrumequinum and large Myotis. For<br />
the comparison, we focused on 19 caves and analyzed abundance of nine<br />
taxa: Miniopterus schreibersii, Myotis capaccinii, M. emarginatus, M.<br />
blythii, M. myotis, Rhinolophus euryale, R. blasii, R. ferrumequinum, and<br />
R. hipposideros. Myotis blythii and M. myotis, and Rhinolophus euryale<br />
and R. blasii were pooled together as large Myotis and medium-size<br />
Rhinolophus species, respectively. In winter and in summer 2001 the total<br />
number of recorded bats was ca. 36000 and 14000, respectively. The total<br />
abundance in 2001 was somewhat larger than in 2009 (ca. 30000 and<br />
12000). In both time periods, and in both seasons, all analyzed species<br />
showed similar clamped distribution (as estimated by high values of<br />
Green's index). Similarly, the Hill's diversity indices and evenness indices<br />
did not show any drastic differences. The observed discrepancy in the<br />
total abundance of bats, we link to almost twofold decrease in abundance<br />
Miniopterus schreibersii and medium-size Rhinolophus species during<br />
summer months from 2001 to 2009. In winter months, a similar trend was<br />
observed in large Myotis and again in medium-size Rhinolophus species.<br />
Whereas Miniopterus schreibersii and in large Myotis appear to show<br />
only seasonal changes, decrease in abundance of medium-size<br />
Rhinolophus species seem to be consistent and might indicate a<br />
population decline of these species. We also report the first record of<br />
White Nose Syndrome in Turkey, which has been detected in a cave close<br />
to the Bulgarian state border on a large Myotis species.<br />

1. Leaf litter constitutes the major source of organic matter and energy in<br />
woodland stream ecosystems. A substantial part of leaf litter entering<br />
running waters may be buried in the streambed as a consequence of<br />
flooding and sediment movement. While decomposition of leaf litter in<br />
surface waters is relatively well understood, its fate when incorporated<br />
into river sediments, as well as the involvement of invertebrate and fungal<br />
decomposers in such conditions, remain poorly documented. 2. We tested<br />
experimentally the hypotheses that the small interstices of the sediment<br />
restrict the access of the largest shredders to buried organic matter<br />
without compromising that of aquatic hyphomycetes and that fungal<br />

decomposers in the hyporheic zone, at least partly, compensate for the<br />
role of invertebrate detritivores in the benthic zone. 3. Alder leaves were<br />
introduced in a stream either buried in the sediment (hyporheic), buried<br />
after 2 weeks of exposure at the sediment surface (benthic-hyporheic), or<br />
exposed at the sediment surface for the entire experiment (benthic). Leaf<br />
decomposition was markedly faster on the streambed surface than in the<br />
two other treatments (2.1- and 2.8-fold faster than in the benthichyporheic<br />
and hyporheic treatments, respectively). 4. Fungal assemblages<br />
were generally less diverse in the hyporheic habitat with a few species<br />
tending to be relatively favoured by such conditions. Both fungal biomass<br />
and sporulation rates were reduced in the hyporheic treatment, with the<br />
leaves subject to the benthic-hyporheic treatment exhibiting an<br />
intermediate pattern. The initial 2-week stage in the benthic habitat<br />
shaped the fungal assemblages, even for leaves later subjected to the<br />
hyporheic conditions. 5. The abundance and biomass of shredders<br />
drastically decreased with burial, except for Leuctra spp., which<br />
increased and was by far the most common leaf-associated taxon in the<br />
hyporheic zone. Leuctra spp. was one of the rare shredder taxa displaying<br />
morphological characteristics that increased performance within the<br />
limited space of sediment interstices. 6. The carbon budgets indicated that<br />
the relative contributions of the two main decomposers, shredders and<br />
fungi, varied considerably depending on the location within the<br />
streambed. While the shredder biomass represented almost 50% of the<br />
initial carbon transformed after 80 days in the benthic treatment, its<br />
contribution was
