Cavefish lack melanin synthesis in regressed pigment cells due to loss-of-function mutations in oca2, which normally regulates the supply of L-DOPA precursor during melanin synthesis. The block in cavefish pigmentation occurs at a metabolic branch point in which L-tyrosine is normally converted either (1) to L-DOPA, DOPAquinone, and melanin by tyrosinase or (2) to L- DOPA, dopamine, and related catecholamines by tyrosine hydroxylase and other enzymes. A similar block in the initial step of melanin synthesis has evolved independently in the cave plant hopper Oliarus polyphemus and other diverse cave animals. In Astyanax cavefish, the benefit of lost melanin pigment appears to be the production of excess L-DOPA and its derivative dopamine by the second alternative pathway, which promotes constructive development of dopaminergic neurons and enhances the magnitude of adaptive feeding behavior. We conclude that the evolution of beneficial constructive traits could have driven regressive traits via developmental tradeoffs encoded in pleiotropic genes, which adapt cave animals to life in darkness. http://www.icsb2010.net/ JEFFERY (W.

DOI: http://dx.doi.org/10.1111/j.1439- 0310.2010.01785.x. ABS: The cause and significance of variation in echolocation call frequency within hipposiderid bats is not well understood despite an increasing number of allopatric and sympatric examples being documented. We examined variation patterns in the resting frequency (RF) of echolocation calls emitted by the intermediate leaf-nosed bat, Hipposideros larvatus, on a broad geographical scale. Data mining technology and Kruskal-Wallis test both showed substantial variation with a longitudinal pattern in RF in H. larvatus among colonies, and this variation was associated with geographical distance and not body size. In addition, we found that a high degree of variability between individuals was hidden under the geographical variation. The results support an effect of random cultural drift, and challenge the prey detection hypothesis. Moreover, an acoustic difference among local island colonies may be indicative of a vocal dialect. We found that each colony of H. larvatus seems to maintain a "private bandwidth", which could be used for colony identity and individual communication thus helping individuals and colonies to get a number of fitness benefits.

Bernard LEBRETON & Jean-Pierre BESSON Créé le : 01.01.2010 Modifié le : 30.06.2010 ABS: Diverse biogenic and abiogenic processes produce calcite speleothems. From a biogenic perspective, cave microbes mediate a wide range of destructive and constructive processes that collectively influence the growth of calcite speleothems and their internal fabrics. Destructive processes include substrate breakdown by dissolution, boring and residue micrite production, whereas constructive processes include microbe calcification, trapping and binding of detrital particles to substrates, and microbial induced calcite precipitation. Biogenesis can be established from: (1) the presence of mineralized microbes; (2) fabrics, such as stromatolite-like structures, that can be attributed to microbial activity; and/or (3) geochemical proxies (carbon and oxygen isotopes, lipid biomarkers) considered indicative of microbe activity. Such criteria have, for example, been used to demonstrate microbial involvement in the formation of pool fingers, stalactites/stalagmites, cave pisoliths and moonmilk. Nevertheless, absolute proof of microbial biogenesis in calcitic speleothems is commonly difficult because taphonomic processes and/or diagenetic processes commonly mask evidence of microbial activity. The assumption that calcitic speleothems are abiogenic, which has been tacitly assumed in many studies, is dangerous as there is clear evidence that microbes thrive in most caves and can directly and indirectly influence calcite precipitation in many different ways.

ABS: A recent study in BMC Evolutionary Biology has reconstructed the molecular phylogeny of a large Mediterranean cave-dwelling beetle clade, revealing an ancient origin and strong geographic structuring. It seems likely that diversification of this clade in the Oligocene was seeded by an ancestor already adapted to subterranean life.

ABS: Cave animals have historically attracted the attention of evolutionary biologists because of their bizarre "regressive" characters and convergent evolution. However, understanding of their biogeographic and evolutionary history, including mechanisms of speciation, has remained elusive. In the last decade, molecular data have been obtained for subterranean taxa and their surface relatives, which have allowed some of the classical debates on the evolution of cave fauna to be revisited. Here, we review some of the major studies, focusing on the contribution of phylogeography in the following areas: biogeographic history and the relative roles of dispersal and vicariance, colonization history, cryptic species diversity and modes of speciation of cave animals. We further consider the limitations of current research and prospects for the future. Phylogeographic studies have confirmed that cave species are often cryptic, with highly restricted distributions, but have also shown that their divergence and potential speciation may occur despite the presence of gene flow from surface populations. Significantly, phylogeographic studies have provided evidence for speciation and adaptive evolution within the confines of cave environments, questioning the assumption that cave species evolved directly from surface ancestors. Recent technical developments involving "next generation" DNA sequencing and theoretical developments in coalescent and population modelling are likely to revolutionize the field further, particularly in the study of speciation and the genetic basis of adaptation and convergent evolution within subterranean habitats. In summary, phylogeographic studies have provided an unprecedented insight into the evolution of these unique fauna, and the future of the field should be inspiring and data rich.

ABS: The MSS was discovered by Juberthie et al. (1980, 1981) in the French Pyrenees, then in 1981 in Carpathian Mountains in Romania (Juberthie et al.). At the same time Ueno described in Japan the Upper Hypogean Habitat. In 1986, Oromi et al. described from Canary Islands a Volcanic MSS type found also in Hawaii by Howarth. The MSS is present in mountains of the temperate zone. The MSS is recorded at least from: Canary Islands, Spain, France, Italy, Austria, Czech Republic, Slovenia, Romania, Bulgaria, Greece, Turkey, Japan, Taiwan, China, Hawaii. The MSS is located beneath the last mineral horizon of soil and the compact bedrock. The more frequent MSS is composed of a network of small voids in screes covered by soil. When a soil has covered the scree, a climatic subterranean habitat, similar to the climate of caves is generated and a new MSS is available for colonization. The difference consists in the greater range of seasonal temperature variations. In karstic areas the MSS lies at the foot of carbonated cliffs; it can be connected with caves. The second type is very superficial cracks of the rocks, covered by soil. The third type is the Volcanic MSS in scoriaceous layers or in some types of lava flow, or in combination of the first and the second. The MSS extends the subterranean habitat. It is present in karstic areas but mainly in other types of rocks, without caves. Trophic resources consist in organic matters introduced by meteoric waters, and soil animals which penetrate passively or actively. Two fauna communities inhabit the MSS: one specific to the MSS, and the other composed of selected soil dwellers. The specific community is composed of troglophile and troglobiotic species, the same as in caves, or specific to MSS. Dominant group, the Coleoptera Trechinae and Leptodirinae: around 120 troglobitic species, and 46 genera. Also found are: Isopoda, Pseudoscorpiones, Araneae, Chilopoda, Diplopoda, Collembola, Campodea, Blattaria, Orthoptera, Diptera. In Pyrenees, a scree on a slope of a glacial valley was formed at the end of the last glacial period, from 24000 to 12000 BP, the genesis of the MSS began 12000-13000 years ago when climate changed, and a soil covered the scree. It was colonized by Coleoptera Aphaenops and Speonomus migrating from small populations surviving in limestone caves in the neighbouring karstic massif. The MSS is really a permanent subterranean habitat similar to caves. http://www.icsb2010.net/ JUGOVIC (J.), 2010.

ABS: Cave shrimps of the subgenus Troglocaris (Crustacea: Decapoda: Atyidae), exhibit high variability in rostral length and dentition. In the shrimp populations that are co-occurring with its amphibian predator Proteus anguinus, longer rostra armed with more numerous teeth are recorded. These shrimps are also larger than the ones living in the presumably Proteus-free environment. Discrepancies between the molecularly established phylogenetic relations and distributions of rostral length, as well as body size, directed our search towards possible environmental influences and possible defence mechanisms of cave shrimps. Although there are some exceptions, the common use of the rostral length is disputable in the diagnoses of the Atyid taxa. In preliminary laboratory observations no successful frontal attack of Proteus was recorded on shrimps with long rostra. Also, a handling time of Proteus feeding on shrimps with long rostra was longer. http://www.icsb2010.net/ Bernard LEBRETON & Jean-Pierre BESSON Créé le : 01.01.2010 Modifié le : 30.06.2010 JUGOVIC (J.), PREVORČNIK (S.), BLEJEC (A.) & SKET (B.), 2010. Linking molecular phylogeny to morphological evolution in Troglocaris (Crustacea: Decapoda: Atyidae):58. 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: Ever since first species of Troglocaris (Dormitzer, 1853) was described the taxonomy of the genus has been unresolved. Only after the phylogenetic reconstruction (COI, 16S rRNA and 28S rRNA) of the putative Troglocaris taxa from three separated distribution areas - from the Dinarides (Western Balkan Peninsula), S France and Caucasus - their phylogenetic relationships were revealed. The only French species was relocated into a new genus as Gallocaris inermis Sket & Zakšek, 2009, being more closely related to the epigean Dugastella valentina (Ferrer Galdiano, 1924) than to its supposed congeners. The taxa from the other two areas constitute a monophylum comprising the Caucasian Xiphocaridinella Sadovsky, 1930, and three Dinaric subgenera: sg. Troglocaris (= Troglocaris s. str.), sg. Spelaeocaris Matjašič, 1956 and sg. Troglocaridella Babić, 1922. Eleven species and phylogroups of the Dinaric subgenera were morphometrically analysed. The accordance of morphology and molecular data is demonstrated by multivariate statistical analyses. Although already a set of non-sexual characters enables distinct separation of all subgenera, optimal accordance of morphological and molecular data is achieved by the consideration of sexual characters in adult males. At the subgeneric level, both phylogenetic subclades of the subgenus Spelaeocaris are morphologically recognized, together with most of their species. In Troglocaris s. str., however, only a combination of numerous characters can separate phylogroups to some extent. A few characters, inappropriate for the multivariate statistics support the separation additionally. While the majority of the morphometric characters seem to be a subject of a phylogenetic patrimony, rostral characteristics and body size may be a result of adaptation. Eventually, the molecular approach remains the most appropriate for a reliable determination of the most Troglocaris s. str. species and phylogroups. http://www.icsb2010.net/ JURADO (V.), PORCA (E.), CUEZVA (S.), FERNANDEZ-CORTES (A.), SÁNCHEZ-MORAL (S.) & SÁIZ-JIMÉNEZ (C.), 2010.

Despite of extensive control, on 26 August 2008 the cave walls and sediments appeared colonized by long, white fungal mycelia. This event was the result of an accidental input of detritus on the afternoon of 24 August 2008.

Preliminary Survey of Copepods from Cueva Clara, Río Camuy Caves Park, Puerto Rico. Espeleorevista Puerto Rico 3(Junio- Diciembre):13-16. ABS: Recent surveys have recorded cosmopolitan cyclopoid copepods such as Macrocyclops albidus, Mesocyclops aspericorni, Microcyclops varicans and Eucyclops agilis from Cueva Clara de Empalme (or Cueva Clara) in the Río Camuy Caves Park of the Río Camuy Cave System (RCCS) in the northern karst of Puerto Rico. Our findings do not support the widely accepted notion that cave dwelling organisms are for the most part endemic and/or highly specialized species, leading to the conclusion that not all cave fauna is necessarily endemic. Further detailed examination of cave-dwelling copepod fauna using molecular techniques would prove beneficial in determining whether species found are indeed individuals of a particular species with a wide distribution, or if the presence of cryptic species is a viable explanation.
