© Biospeologica Bibliographia Publications 2010-1 Page 38 sur 116 inhabiting ground waters of Slovenia depict a fauna of approximately 50 species, 20 of which are stygobionts. In the last decades, new researches in Slovenian ground waters enabled us to study into more depth the oligochaete fauna of this environment. The studied material resulted from three main sources: a campaign in Slovenian caves conducted by Fabio STOCH, a large collection of groundwater fauna made available to us by Boris SKET, and samples collected during the European project PASCALIS. The data derived from the examination of this large amount of material enabled us to broaden the faunistic spectrum of oligochaetes of Slovenia, as well as to show that the oligochaete biodiversity in Slovenian ground waters is a substantial fraction of the European one. Endemic and very rare species constitute a remarkable proportion of the stygobiont oligochaete fauna. Among these, the genera Rhyacodriloides, Cernosvitoviella, Parvidrilus, Trichodrilus and Haber are some of the most outstanding taxa. In Pajsarjeva Cave, which was sampled many times over the past 15 years, the sporadic presence of some species, as well as the high rate of presence of stygobionts lead us to formulate a hypothesis about the relationship between the faunal data and the hydrogeology of the cave. http://www.icsb2010.net/ GIBERT (J.), GEOFFROY (J.-J.) & MESSANA (G.), 2010.

Echolocation behavior of Brazilian free-tailed bats during dense emergence flights. Journal of Mammalogy 91(4):967-975. DOI: http://dx.doi.org/10.1644/09-MAMM-A-302.1. ABS: Brazilian free-tailed bats (Tadarida brasiliensis) emerge from cave roosts in dense columns in which adjacent bats are separated by only small distances. We describe and quantify variation in the structure of echolocation calls produced by these emerging bats and determine if call structure changes in relation to the rate of emergence measured using thermal infrared imaging. We recorded emergence calls at 2 roosts, 1 housing approximately 200000 bats and the other approximately 17000 bats. We found that Brazilian free-tailed bats emit distinct frequencymodulated (FMstart) and constant frequency (CFstart) calls during emergence that are significantly different from echolocation calls they emit while foraging. We propose that these calls provide different information for orientation within the emergence column. CFstart calls are very similar to social calls used by Brazilian free-tailed bats, suggesting 2 potential functions for this call type. The structure of both the FMstart and CFstart calls were not related to the number of bats emerging from a roost, although significant structural differences existed between sites. The differences between sites could be associated with the spacing of bats during emergence, because bats appeared to form tighter columns at the larger roost colony compared to the smaller colony.

Pteridòfits i briòfits de les cavitats de la serra de na Burguesa (Serra de Tramuntana, Mallorca). Endins 34:69-86. RES: Se citen els pteridòfits i els briòfits que s'han observat tant a les cavitats naturals com a les mines i pedreres de la serra de na Burguesa. En comparació amb la zona central de la serra de Tramuntana, no hi ha una flora briofítica i pteridofítica relictual, exceptuant Homalia lusitanica i Asplenium scolopendrium que s'han trobat a una única cavitat, el Clot des Sero. Asplenium sagittatum s'ha observat a 15 cavitats i en una d'aquestes ha desaparegut una població, per causes desconegudes, en un període d'uns sis anys. Anogramma leptophylla, Asplenium petrarchae i Asplenium trichomanes subsp. inexpectans és la primera vegada que se citen en aquesta serra. ABS: We have studied the pteridophytes and bryophytes observed in natural cavities as well as in mines and quarries of Na Burguesa mountain range. Compared with the central area of the Tramuntana mountains, it is not present a relictual bryophyte and pteridophyte flora, except Homalia lusitanica and Asplenium scolopendrium found at a single cavity, the Clot des Sero. Asplenium sagittatum was observed in 15 of these cavities and in one of them it was noticed its decline for unknown reasons, during the last six years. Anogramma leptophylla, Asplenium petrarchae and Asplenium trichomanes subsp. inexpectans are recorded for the first time in this area. GIRARD-CLAUDON (J.), 2010. Évolutions récentes des populations de chiroptères en région Rhône-Alpes: essai Bernard LEBRETON & Jean-Pierre BESSON Créé le : 01.01.2010 Modifié le : 30.06.2010 de synthèse [Recent evolution of bat populations in Rhone- Alpes: a synthesis]. Bulletin mensuel de la Société linnéenne de Lyon, hors-série n° 2:? RÉS: Le groupe des chiroptères compte trente-quatre espèces en France. En raison de leurs mœurs nocturnes, ces mammifères n'ont été étudiés que tardivement. En effet, il n'y avait que peu de chiroptérologues dans la région jusqu'à la moitié du vingtième siècle. Au cours de la fin de ce siècle, le nombre de spécialistes a considérablement augmenté et les techniques d'études des chauves-souris se sont largement développées et diversifiées. Cet article est un essai de synthèse sur l'évolution des populations de chauves-souris en Rhône-Alpes. Nous pouvons distinguer deux périodes différentes: - Au cours des années 1950-1960, les populations de chauves-souris se sont effondrées en France, probablement en raison des activités humaines (modification dans les pratiques agricoles, urbanisation, transport, tourisme souterrain, etc.). - Au cours de la fin du vingtième siècle des suivis ont été mis en place progressivement par les chiroptérologues. Malgré le peu de recul, des tendances d'évolutions semblent se dégager. Ainsi nous pouvons par exemple dire qu'il semblerait que les effectifs des populations de rhinolophes (Rhinolophus hipposideros et R. ferrumequinum) augmentent, de même que ceux des murins de grande taille (Myotis myotis et M. oxygnathus). Ces interprétations sont toutefois à prendre avec précaution et à relativiser avec la taille des populations existantes au début du vingtième siècle. Les suivis mis en place actuellement sont à maintenir sur le long terme afin de détecter toutes nouvelles fluctuations. En parallèle les actions de conservation doivent être poursuivies et amplifiées pour éviter tout nouveau déclin d'origine anthropique. ABS: The Chiroptera include 34 species in France. As a result of their nocturnal habits, these mammals have only lately been studied. Indeed, there were few chiropterologists until the mid-20 th century. Throughout the second half of the century the number of specialists has increased considerably and the techniques of studies of bats widely developed and diversified. This article is an attempt to synthesise information on the evolution of the bat populations in Rhone- Alpes. We can distinguish two different periods: i) during the 50's and 60's bat populations collapsed in France, probably as a result of human activity (changes in agricultural practices, urbanisation, transport, subterranean tourism etc.) ii - towards the end of the 20 th century surveys were progressively implemented by chiropterologists. Despite the limited period concerned, the evolutionary trends seem to have halted. Thus we can, for instance, state that it appears that the population densities of horseshoe bats (Rhinolophus hipposideros, R. ferrumequinum) are increasing, as are those of the mouse-eared bats (Myotis myotis and M. oxygnathus). These interpretations are nevertheless to be taken with caution and weighed against the size of populations existing at the beginning of the 20 th century. Current studies need to be maintained longterm to detect any new fluctuations. In parallel, conservation measures should be pursued and increased, in order to avoid further decline as a result of human intervention. http://www.linneennelyon.org/rubrique.php3?id_rubrique=41 GIRIBET (G.), VOGT (L.), PÉREZ GONZÁLEZ (A.), SHARMA (P.) & KURY (A.), 2010.

Ecological and hydrobiological characteristics]. Ecologia mediterranea 36(1):25-44. RÉS: Les cours d'eau à régime karstique sont alimentés par des aquifères souterrains. Leurs caractéristiques physico-chimiques sont: la faible variabilité des débits, car les apports d'eau souterraine assurent des débits réguliers avec des étiages peu marqués et des crues modérées; la température de l'eau, basse et constante sur la totalité ou sur une partie importante du cours; la minéralisation élevée des eaux de surface, avec de fortes teneurs en calcium. Ces caractéristiques confèrent aux cours d'eau karstiques des spécificités écologiques et faunistiques originales, atypiques dans le contexte régional méditerranéen. Le présent article porte sur quatre cours d'eau à régime karstique: l'Argens (Var), la Siagne et le Loup (Alpes-Maritimes), les Sorgues (Vaucluse). Il met en évidence leur originalité hydroécologique et surtout les particularités de leur peuplement analysées à travers la faune de macroinvertébrés. La

Une des particularités faunistiques les plus remarquables, commune à ces cours d'eau, est la présence d'espèces sténothermes d'eau froide qui vivent habituellement dans le crénal et le rhithral des cours d'eau de montagne, à des altitudes bien supérieures à celles où elles ont été récoltées dans les cours d'eau karstiques. Une analyse comparative du statut écologique de 11 espèces sténothermes, que l'on trouve à la fois dans les cours d'eau de régime karstique et dans les cours d'eau de type méditerranéen, a été réalisée. De plus, les cours d'eau recevant les apports des systèmes karstiques hébergent des populations qui, du fait de leur caractère sténotherme, se sont trouvées isolées par rapport aux cours d'eau méditerranéens adjacents. Ceci explique la présence d'espèces endémiques. En définitive, les cours d'eau de régime karstique, bien qu'ils soient assez nombreux, sont atypiques dans la région méditerranéenne. On y trouve des conditions hydrologiques, thermiques et des peuplements (ripisylves, biocénoses, populations) qui sont habituellement présents dans des cours d'eau de montagne et dans des cours d'eau médioeuropéens.

ABS: Seasonnality and variability in rainfall is the principal attribute of Mediterranean-type climate. As a consequence, Mediterranean-type streams exhibit strong seasonnal variability which can lead to extreme conditions of flooding and drying. Large areas of karst geology occur in the Mediterranean region, consequently large amounts of water may be stored in subterranean aquifers; so, many karstic streams occur in Mediterraneanclimate areas. Karstic streams are lotic habitats supplied from underground water in contrast to surface run-off, and this gives them some characteristics quite different from those of other true Mediterranean streams; mainly, water conditions are more regular and uniform. Karstic streams, vary little in flow volume and temperature all year round (the temperature fluctuates by only a few degrees, even in areas with cold winters and warm summers; summer temperatures seldom exceed 20°C). Moreover, water issuing from sedimentary rocks, such as limestones, contains large amount of dissolved salts, notably calcium bicarbonate; these streams are liable to deposit calcium carbonate (tufa concretions). The present paper concerns four karstic watercourses in Provence (South-East France); it relates the influence of the ground water supplying on hydrology, ecology and hydrobiology of streams issuing from limestone formations. The peculiarities of these streams and the specificities of their animal community, analized through the knowledge of their macroinvertebrate fauna, are pointed out. In the studied karstic streams, the invertebrate community is dominated in numbers by taxa (Crustacea Gammarus, Coleoptera Elmidae, Gasteropoda) regularly found in strongly mineralized water-courses with high Ca contents; these taxa have always been found associated. In addition to that, two species of Diptera Simuliids, Simulium xanthinum and S. galloprovinciale, occur on tufa (from Spain to Libanon). One of the most noteworthy faunal peculiarity, common to karstic hydrologic regime watercourses, is the occcurence of a lot of coldstenothermous invertebrates which usually live at higher altitudes in mountain streams and in springs. Their occurrence in Mediterranean streams at middle and low altitudes is atypic. This peculiarity is correlated with thermal regime of the karstic streams which appear as cold enclaves in the Mediterranean region. The ecology of 11 cold-stenothermous species (1 Planarian, 3 Ephemeroptera, 2 Plecoptera, 4 Trichoptera, 1 Blepharicerid) which are both inhabitants of karstic and of non-karstic streams in the same mediterranean region (South-East France) is compared. The invertebrate community of karstic streams also contains some endemic species. The most worthy of note is Rhyacophila vallisclausae, a caddisfly (Trichoptera) which lives in the upper reach of the river Sorgue. This species, belonging to the European group of R. vulgaris, is clearly distinguished from all species in this group by the strongly marked brachyptery of specimens; it appears to be a relic remnant of an ice age fauna which could survive in an aquatic environment characterized by its remarquable cold stenothermy.

In: 20 th International Conference on Subterranean Biology, Postojna, Slovenia, 29 August-3 September 2010, ICSB 2010 Abstract Book, edited by: Ajda MOŠKRIČ and Peter TRONTELJ, ISBN 978-961-269-286-5. ABS: The protection of ecological communities within ground water, as distinct from groundwater-dependent surface ecosystems, is relatively novel in water resource management policy. Given the international focus on protection of ground water communities, it is pleasing to note that Australia, in particular Western Australia (WA), is considered among the scientific community as world leading in its recognition of the need to protect groundwater resources and their dependent ecosystems through water resource policy. In WA, there is considerable regulatory focus currently on the protection of groundwater-dependent stygofauna as competing priorities to develop groundwater resources for human use begin to be realised. Accordingly, in the past 10 years, collaboration between speleologists, scientists, and government institutions has been matched by increased regulatory focus - requiring commercial and industrial proponents to fund surveillance programs to inform proposals undergoing Environmental Impact Assessments (EIA) by the Environmental Protection Authority (EPA). Yet, contrary to external perceptions, the collaboration has not been without its difficulties due to inconsistent application of the EPA guidance by administrative authorities and a general uncertainty over a proponent's legal obligations towards protecting stygofauna. During the years 2005-2009 I investigated whether the regulatory framework in WA, ostensibly designed to protect stygofauna, really achieves that objective - specifically in the context of abstraction of ground water for the town of Exmouth in northern WA. Particularly, I sought to unravel the confusion over legal and regulatory responsibilities towards stygofauna conservation and clarify the true statutory protection afforded to these animals under national and WA State laws. Here, I discuss: (i) an overview of historic and present-day Commonwealth and WA State legislation providing directly or indirectly for protection of stygofauna; (ii) inconsistencies and/or limitations of administrative and policy documents used to regulate stygofauna conservation; and, (iii) avenues for improving links between regulatory, scientific and societal groups to better protect stygofauna in Australia. http://www.icsb2010.net/ GODLEVSKA (L.), GHAZALI (M.), KHOKHLOVA (A.) & TYSHCHENKO (V.), 2010. Bat key underground sites in eastern Crimea, Ukraine: Numbers, threats and future:150-151. In: 15 th International Bat Research Conference, Prague, 22-27 August 2010, the conference manual: Programme, abstracts, list of participants, edited by: Ivan HORÁČEK and Petr BENDA, ISBN 978-80- 87154-46-5, 380 p. ABS: In 2000 Ukrainian bat-workers started a systematical work on survey and inventory of bat fauna of the Crimean peninsula (southern Ukraine), mainly in connection with bat underground roosts. Unique large bat aggregations were discovered in underground cavities of eastern Crimea: nine important bat sites were found. All of them are anthropogenic, mostly represented by limestone mines of different length (up to 50 km). In summer, the sites are used by ca. 26000 bat individuals, represented mostly by maternity and male colonies of Myotis blythii and Rhinolophus ferrumequinum. The most detailed census in winter 2010 revealed more than 21000 bat individuals (ca. 79% M. blythii, 20% R. ferrumequinum). Besides these two species three more were found regularly: Myotis mystacinus, Plecotus austriacus, Eptesicus serotinus. It was revealed that most of cavities are important bat mating sites. Evidently, all the sites are located at the relatively small area (a distance between the outermost sites is 75 km) and may create a united roost complex. The bat aggregations are the biggest in Ukraine. However, all of them are under constant threats. Among them there are: attendance cavities by people and directed full or partial blocking of entrances, leading to closing of cavities for bats or to critical changes in existing favorable for bats microclimatic conditions. A characteristic feature of many mine objects is presence of the great number of entrances. Thus, standard methods of protection (by putting grilles or fences at their entrances) are not applicable here. A work on conservation of the sites,
