<strong>2010</strong> Abstract Book, edited by: Ajda MOŠKRIČ and Peter<br />
TRONTELJ, ISBN 978-961-269-286-5. ABS: In comparison<br />
with the other amphibians Proteus has very extended reproductive period,<br />
continuing 30 years or more and it has an extremely long reproductive<br />
cycles, that is to say Proteus' female lays eggs at intervals of 6 years.<br />
Sexual maturity is also acquired very late, with males maturing earlier<br />
than females, appears in 11 year-old males and 15 year-old females at 11-<br />
12°C. Opposite to the knowledge of reproduction, little is known about<br />
Proteus oogenesis; a process of differentiation and maturing of the<br />
oocyte, resulting in the mature ovum capable of ovulation. To gain a<br />
better understanding and elucidation of the Proteus reproductive cycles,<br />
we have begun with studies of its ovary and oogenesis. Ovaries of 30<br />
females of Proteus anguinus anguinus, with snout-vent lengths of 225 -<br />
270 mm were examined by light and transmission electron microscopy.<br />
The gonad samples used in this research were taken from animals that<br />
had been collected in previous years (from 1972 to 2009) for other<br />
research purposes. Animals had been collected during different seasons<br />
and from different locations of the subterranean karstic system of<br />
Slovenia. The morphology of the Proteus ovary, the stages of oocytes and<br />
characteristics of developmental oocytes were determined. The oocytes<br />
were divided into five stages based on size, colour and histology. The<br />
most predominant oocytes in the ovaries of Proteus beside the oogonium<br />
are previtellogenic oocytes (stage I and II). Oogonium and previtellogenic<br />
oocytes are a constant stock of oocytes for growth. In a few cases, early<br />
vitellogenic oocytes (stage III and IV) and only in two cases late<br />
vitellogenic oocytes (stage V) were encountered. Stage V oocytes are the<br />
most mature oocytes found in the ovary of Proteus. No mature<br />
(postvitellogenic) oocytes or ova were found in the materials that were<br />
available. In majority of ovaries examined a degenerating vitellogenic<br />
oocytes or atretic bodies occurred too. Furthermore, we found that larger<br />
and heavier females have more mature oocyte stages and also that<br />
vitellogenic oocytes occur in ovaries independently of seasons, therefore<br />
Proteus females could lay eggs at any period of the year.<br />

White Nose Syndrome (WNS) is a disease associated with unprecedented<br />
bat mortality in the eastern United States and Canada. Since the winter of<br />
2006-2007, bat population declines approaching 100% have been<br />
documented at some long-surveyed hibernacula. At least six species of<br />
hibernating bats are susceptible to WNS. Total estimated losses have<br />
exceeded one million bats over the past three years. This presentation<br />
summarizes disease investigation efforts underway at the USGS National<br />
Wildlife Health Center since January 2008. Affected hibernating bats<br />
often present with visually striking white fungal growth on their muzzles,<br />
ears, and/or wing membranes. However, severe microscopic wing<br />
damage associated with the disease is not always obvious to the naked<br />
eye. Histopathological and microbiological analyses demonstrated that<br />
WNS is characterized by a hallmark fungal skin lesion caused by a<br />
recently discovered species of psychrophilic (cold-loving) fungus,<br />
Geomyces destructans. The fungus invades and erodes living tissue and<br />
grows optimally between 5°C and 14°C, temperatures consistent with the<br />
body temperatures of hibernating bats. Laboratory infection trials<br />
indicated that Geomycetes destructans is transmissible from bat to bat. A<br />
genetic signature of the fungus has been identified in environmental<br />
samples collected from several bat hibernation caves within WNSinfested<br />
states. There is a growing body of evidence supporting an<br />
association between WNS and life-threatening cutaneous fungal infection<br />
by G. destructans, and this disease represents an unprecedented threat to<br />
bats of temperate regions of North America and beyond. The decline of<br />
North American bat populations may have far-reaching ecological<br />
consequences.<br />

269-286-5. ABS: The genus Aphaobius was established in 1878 by<br />
Abeille de Perrin to segregate the species Adelops milleri (Schmidt,<br />
1855). A few years later, the species A. heydeni was described by Reitter.<br />
After the first decade of the 20 th century eleven new taxa were described<br />
by J. Muller. Further three subspecies of A. milleri were described in the<br />
ensuing decades by Mandl and then a new, remarkably distinct species<br />
was found and described by Pretner in 1963 as A. muellerianus. Only<br />
recently, new investigations led to the discovery of the new species A.<br />
grottoloi (Vailati, 2004). Following the latest revision (Bognolo &<br />
Vailati, <strong>2010</strong>), the genus is composed of four species groups:<br />
muellerianus, heydeni, kraussi and milleri. The northern kraussi group is<br />
a cluster of species distributed on the left-hand side of the river Sava,<br />
which includes A. mixanigi, A. angusticollis, A. knirschi, A. brevicornis<br />
and A. kraussi. The southern milleri group is a cluster of species<br />
distributed on the right-hand side of the river Sava, which includes A.<br />
forojulensis, A. grottoloi, A. lebenbaueri, A. miricae, A. kaplai, A.<br />
fortesculptus, A. robustus, A. kahleni, A. milleri, A. ljubnicensis, A. kofleri<br />
and A. alphonsi. The muellerianus group and the heydeni group include<br />
one species each: A. muellerianus and A. heydeni. The overall distribution<br />
of the genus Aphaobius shows a combination of species with large<br />
distribution areas and other species known from a single site or a very<br />
restricted geographic area. The correlation of paleogeographic features<br />
and allopatric speciation is evident when considering the kraussi and the<br />
milleri species groups. In particular, the northern kraussi group is<br />
geographically located within the Southern Alps, whilst the southern<br />
milleri group is mainly located on the Outer Dinarides. In particular, in<br />
central Slovenia such groups have long been isolated due to the<br />
movement of respective plates which, according to plate tectonics, slid<br />
along the contact boundary represented by the Sava fault. To sum up, the<br />
speciation patterns of the genus Aphaobius show past isolation in the<br />
region between Ljubljana and Železniki, characterised by the complex<br />
paleogeographic evolution, as opposed to a high dispersal activity of the<br />
southern area, along the typical north-west to south-east orientation of<br />
limestones in the northern Balkan area. http://www.icsb<strong>2010</strong>.net/<br />

ABS: We surveyed the Tsingy de Bemaraha plateau in central-western<br />
Madagascar for amphibians and reptiles. We recorded 19 species of<br />
amphibians and 60 species of reptiles by opportunistic searching,<br />
bioacoustic identification (frogs), and pitfall trapping. Among the species<br />
recorded, 13% were previously unknown to science and a further 15% are<br />
of uncertain taxonomic status and possibly represent undescribed species.<br />
Of all the species recorded, 28% are endemic to the Bemaraha plateau<br />
and 48% appear to be dependent on forest habitat. Phylogenetic<br />
relationships of Bemaraha amphibians suggest a biogeographic link to<br />
eastern rainforests; whereas, those of reptiles demonstrate a link to the<br />
forests of northern Madagascar. We comment on former species records<br />
from the area and discuss conservation issues for amphibians and reptiles<br />
related to the habitat alteration observed in several parts of the protected<br />
area complex. KW: Amphibia, biogeography, checklist, conservation,<br />

surveillé les amphibiens et les reptiles dans le plateau du Tsingy de<br />
Bemaraha dans le central-ouest de Madagascar. Nous avons recensé 19<br />
espèces d'amphibiens et 60 espèces de reptiles par des recherches<br />
opportunistes, identification bioacoustique (amphibiens) et des piégeages<br />
par trous pièges. Parmi les espèces recensées, 13% sont auparavant<br />
inconnues par la science et plus de 15% ont des statuts taxonomiques<br />
incertains et sont possibles des espèces non-décrites. 28% de toutes les<br />
espèces recensées sont considérées pour représenter les endémicités à<br />
Bemaraha et 48% des espèces pourraient être dépendantes de l'habitat<br />
forestier. Les relations phylogénétiques des amphibiens de Bemaraha<br />
indiquent une continuité biogéographique aux forêts humides de l'Est et<br />
celles de reptiles une continuité aux forêts au nord de Madagascar. Nous<br />
avons fait des commentaires sur les espèces recensées auparavant dans la<br />
région et avons discuté à propos des actions de conservation des<br />
amphibiens et des reptiles reliées à l'altération des habitats observée dans<br />
certaines parties du complexe aire protégée. MC: Amphibiens,
