presence and documenting new localities. Another important subject is<br />
the study of the history of research of Proteus. Owing to this interest, the<br />
laboratory has put together an extensive library on this species. The<br />
laboratory also raises the public awareness of Proteus as the symbol of<br />
the Slovene natural history, with special emphasis on nature conservation.<br />
Since the beginning, one of the missions of Tular was to establish a<br />
breeding colony, which could reintroduce Proteus back to a destroyed<br />
habitat. This idea became most urgent after the discovery of an extremely<br />
vulnerable and rare P. a. parkelj in SE Slovenia, where even a local<br />
pollution could destroy the entire population. Occasionally, the laboratory<br />
serves as a sanctuary for injured specimens that were washed out of their<br />
subterranean habitat. http://www.icsb<strong>2010</strong>.net/<br />

269-286-5. ABS: The European cave salamander, Proteus anguinus<br />
(Amphibia: Urodela) is restricted to its aquatic cave habitat. However,<br />
during seasonal flooding, some individuals are washed out of their<br />
subterranean environment. In fact, this was the only way to obtain<br />
Proteus through the early decades of its research. Also, many new<br />
localities were discovered on the account of this, obviously not rare,<br />
phenomena. Though this may be considered as a highly hazardous way of<br />
Proteus to disperse into new habitats, it is clear that all these individuals<br />
present a constant loss for their population. There are several suggestions<br />
how Proteus could directly detect the coming flood and search for shelter<br />
(sensing sudden rise of water level/increase of water current, detecting<br />
changes of sound owing to the higher water level/percolating water,<br />
sensing the changes of temperature/chemistry of water, etc.), though non<br />
of them were observed or tested. Recently, another possibility was<br />
proposed by M. Prelovšek. Precise measurements of several physical and<br />
chemical parameters of cave water have revealed a significant rise in<br />
electrical conductivity shortly after first rain, up to several hours before a<br />
substantial rise of the water level. Namely, the rain above the cave<br />
squeezes the old, saturated water from the aquifer. A fast response of<br />
local infiltration of precipitation is followed by higher but later flow of<br />
water from a distant but larger catchment area, which actually brings the<br />
flood, and a rapid decrease of electrical conductivity. On the basis of a<br />
short preliminary behavioural test, performed in the Tular Cave<br />
Laboratory, it was not possible to conclude with certainty whether<br />
Proteus is sensitive to the changes of electrical conductivity in the range<br />
that appears in a cave water prior the flood. Further laboratory<br />
investigation, supported by observation in nature is needed.<br />

http://dx.doi.org/10.1665/034.019.0118. ABS: In this study we<br />
reconstructed the molecular phylogeny and attempted to infer historical<br />
biogeography of a sample of cricket species, most of them cave-dwelling,<br />
belonging to the subfamily Macropathinae (Orthoptera,<br />
Rhaphidophoridae) which shows a clear Gondwanan distribution. We<br />
sequenced fragments of 4 genes (12S rRNA, 16S rRNA, 18S rRNA and<br />
28S rRNA), for a total of 1993 bp. We present here preliminary data<br />
based on a total of 17 species, 11 belonging to Macropathinae and<br />
representative of the main regions of Gondawanaland, 7 to<br />
Aemodogryllinae and Rhaphidophorinae from India, Bhutan, China,<br />
Philippines and the Sulawesi Islands. The use of relaxed molecular clocks<br />
by means of Bayesian analysis allowed us to estimate the timing of the<br />
main cladogenetic events, using calibration of a molecular clock; the<br />
clock is based on the plate disjunction of Africa from South America,<br />
Australia from Zealandia (New Zealand), or Australia from Antarctica.<br />
The latter was considered at two different datings on the basis of two<br />
alternative palaeogeographic hypotheses. Node dating using separation of<br />
Africa or a model of earlier separation of Australia from Antarctica,<br />
suggests that the main cladogenetic events in the Macropathinae<br />
phylogeny could be explained by vicariance hypotheses, related to the<br />
Gondwana fragmentation. However, two other equally valid calibrations<br />

suggest that lineage formation is not consistent with vicariant processes<br />
and requires either some long-distance dispersal, or an inconceivable age<br />
of origin of this family of insects, enabling the prior existence of all<br />
lineages in Gondwanaland with subsequent regional extinction. KW:<br />

<strong>2010</strong> Abstract Book, edited by: Ajda MOŠKRIČ and Peter<br />
TRONTELJ, ISBN 978-961-269-286-5. ABS: This study<br />
focuses on the phylogenetic relationships among ninety percent of known<br />
Dolichopoda species (44 out of 49); primarily a Mediterranean genus,<br />
distributed from eastern Pyrenees to Caucasus. A total of 2490 base pairs<br />
were sequenced corresponding to partial sequences of one nuclear (28S<br />
rRNA) and three mitochondrial genes (12S, 16S and COI). A relaxed<br />
molecular clock, inferred from Bayesian analysis was applied to estimate<br />
the divergence times between the lineages using well dated palaeoevents<br />
of the study areas. Molecular substitution rates per lineage per million<br />
years were also obtained for each analysed gene. Based on the nearly<br />
complete species phylogeny, temporal patterns of diversification were<br />
analysed using Lineage-Through-Time plots and diversification statistics.<br />
Alternative hypotheses about the colonization of western Mediterranean<br />
by Dolichopoda species were tested by means of Approximate Bayesian<br />
Computation analysis and by comparing the degree of discordance<br />
between species trees and gene trees under four plausible biogeographic<br />
scenarios. Both phylogenetic reconstruction and results from the<br />
biogeographical hypotheses test suggested that the current distribution of<br />
Dolichopoda species has been essentially shaped from the<br />
palaeogeographic and climatic events occurred in the Mediterranean<br />
region, starting from Late Miocene up to the Plio-Pleistocene. Our results<br />
suggest that the current distribution of Dolichopoda can be explained by a<br />
combination of both vicariance and dispersal events, with many processes<br />
occurring in ancestral epigean populations before the invasion of the<br />
subterranean environment. http://www.icsb<strong>2010</strong>.net/<br />

1739.<strong>2010</strong>.01624.x. ABS: Since the late 1980s, Brazilian free-tailed<br />
bats (Tadarida brasiliensis) have increasingly used bridges as roosts in<br />
the southern United States. We examined differences in blood cortisol<br />
levels, body condition, and parasite load, as measures of physiological<br />
stress in bats roosting in bridges and bats roosting in caves. We collected<br />
data during three periods, coinciding with female phases of reproduction.<br />
For all measures, bats were captured during the nightly emergence from<br />
the roost and immediately sampled. Cortisol levels were significantly<br />
higher during pregnancy and lactation and in individuals with lower<br />
body-condition scores (length of forearm to mass ratio) and significantly<br />
higher in bats roosting in caves than in those roosting in bridges. Thus,<br />
we concluded that individuals of this species that roost in bridges are not<br />
chronically stressed and seem to be unaffected by human activities<br />
present at bridges. This is a rare documented instance where a humandominated<br />
environment does not appear to be adversely affecting the<br />
physiological health of a free-ranging animal. RES: Desde fines de la<br />
década de 1980, murciélagos (Tadarida brasiliensis) han incrementado el<br />
uso de puentes como perchas en el sur de los Estados Unidos.<br />
Examinamos las diferencias en los niveles de cortisol en la sangre,<br />
condición del cuerpo y carga de parásitos, como medidas del estrés<br />
fisiológico en murciélagos que perchan en puentes y murciélagos que<br />
perchan en cuevas. Recolectamos datos durante 3 períodos, coincidentes<br />
con las fases reproductivas de hembras. Para todas las medidas, los<br />
murciélagos fueron capturados al salir de sus perchas y procesados<br />
inmediatamente. Los niveles de cortisol fueron significativamente<br />
mayores durante el embarazo y la lactancia y en individuos con valores<br />
bajos en la condición del cuerpo (relación longitud del antebrazo - masa)<br />
y significativamente mayores en murciélagos que perchan en cuevas que<br />
en los que perchan en puentes. Por lo tanto, concluimos que los<br />
individuos de esta especie que perchan en puentes no están estresados<br />
crónicamente y parece que las actividades humanas en el puente no les
