Diseases And Causes Of Death In European Bats: Dynamics In Disease Susceptibility And Infection Rates, Kristin Mühldorfer, Stephanie Speck, Andreas Kurth
Diseases And Causes Of Death In European Bats: Dynamics In Disease Susceptibility And Infection Rates, Kristin Mühldorfer, Stephanie Speck, Andreas Kurth
KIP Articles
Bats receive increasing attention in infectious disease studies, because of their well recognized status as reservoir species for various infectious agents. This is even more important, as bats with their capability of long distance dispersal and complex social structures are unique in the way microbes could be spread by these mammalian species. Nevertheless, infection studies in bats are predominantly limited to the identification of specific pathogens presenting a potential health threat to humans. But the impact of infectious agents on the individual host and their importance on bat mortality is largely unknown and has been neglected in most studies published …
The Evolution Of Sensory Divergence In The Context Of Limited Gene Flow In The Bumblebee Bat, Sebastian J. Puechmaille, Meriadeg Ar Gouilh
The Evolution Of Sensory Divergence In The Context Of Limited Gene Flow In The Bumblebee Bat, Sebastian J. Puechmaille, Meriadeg Ar Gouilh
KIP Articles
The sensory drive theory of speciation predicts that populations of the same species inhabiting different environments can differ in sensory traits, and that this sensory difference can ultimately drive speciation. However, even in the best-known examples of sensory ecology driven speciation, it is uncertain whether the variation in sensory traits is the cause or the consequence of a reduction in levels of gene flow. Here we show strong genetic differentiation, no gene flow and large echolocation differences between the allopatric Myanmar and Thai populations of the world's smallest mammal, Craseonycteris thonglongyai, and suggest that geographic isolation most likely preceded sensory …

The Nubian Complex Of Dhofar, Oman: An African Middle Stone Age Industry In Southern Arabia, Jeffery I. Rose, Vitaly I. Usik, Anthony E. Marks
The Nubian Complex Of Dhofar, Oman: An African Middle Stone Age Industry In Southern Arabia, Jeffery I. Rose, Vitaly I. Usik, Anthony E. Marks
KIP Articles
Despite the numerous studies proposing early human population expansions from Africa into Arabia during the Late Pleistocene, no archaeological sites have yet been discovered in Arabia that resemble a specific African industry, which would indicate demographic exchange across the Red Sea. Here we report the discovery of a buried site and more than 100 new surface scatters in the Dhofar region of Oman belonging to a regionally-specific African lithic industry - the late Nubian Complex - known previously only from the northeast and Horn of Africa during Marine Isotope Stage 5, ∼128,000 to 74,000 years ago. Two optically stimulated luminescence …
Feeding Habits Of The Egyptian Fruit Bat Rousettus Aegyptiacus On Cyprus Island: A First Assessment, Maria Alessandra Del Vaglio, Haris Nicolau, Luciano Bosso
Feeding Habits Of The Egyptian Fruit Bat Rousettus Aegyptiacus On Cyprus Island: A First Assessment, Maria Alessandra Del Vaglio, Haris Nicolau, Luciano Bosso
KIP Articles
Rousettus aegyptiacus is the only fruit bat occurring in Europe. A dramatic, poorly understood decline was recently reported for the important population occurring on the island of Cyprus (Eastern Mediterranean). Assessing diet in this population is important to tailor appropriate conservation measures and help mitigate conflicts with farming. In this study, we present a first assessment of diet for the Cyprus population, mainly based on the occurrence of fruit remains in droppings. We analyzed 222 droppings (corresponding to 281 food items) collected at two cave roosts over three seasons. We identified 11 plant species from 8 families. Melia azedarach, Morus …

The Later Stone Age Calvaria From Iwo Eleru, Nigeria: Morphology And Chronology, Katerina Harvati, Chris Stringer, Rainer Grün
KIP Articles
Background: In recent years the Later Stone Age has been redated to a much deeper time depth than previously thought. At the same time, human remains from this time period are scarce in Africa, and even rarer in West Africa. The Iwo Eleru burial is one of the few human skeletal remains associated with Later Stone Age artifacts in that region with a proposed Pleistocene date. We undertook a morphometric reanalysis of this cranium in order to better assess its affinities. We also conducted Uranium-series dating to re-evaluate its chronology. Methodology/Principal Findings: A 3-D geometric morphometric analysis of cranial landmarks …

A Blind Circadian Clock In Cavefish Reveals That Opsins Mediate Peripheral Clock Photoreception, Nicola Cavallari, Elena Frigato, Daniela Vallone
KIP Articles
The circadian clock is synchronized with the day-night cycle primarily by light. Fish represent fascinating models for deciphering the light input pathway to the vertebrate clock since fish cell clocks are regulated by direct light exposure. Here we have performed a comparative, functional analysis of the circadian clock involving the zebrafish that is normally exposed to the day-night cycle and a cavefish species that has evolved in perpetual darkness. Our results reveal that the cavefish retains a food-entrainable clock that oscillates with an infradian period. Importantly, however, this clock is not regulated by light. This comparative study pinpoints the two …

Karst Landforms In An Interior Layered Deposit Within The Coprates Chasma, Mars, Davide Baioni, Nadja Zupan Hajna, Forese Carlo Wezel
KIP Articles
The Coprates Chasma forms part of the backbone of the Valles Marineris canyon system. In the westernmost part of the chasma in an embayment on the northern wall a mound of layered material rises from the chasma floor and displays a characteristic dome-shaped morphology. The mineralogical characteristics of the dome and its surroundings have been determined by analysis of the CRISM (Compact Reconnaissance Imaging Spectrometer for Mars) data (image HRL00003752). The unit shows the clear signatures of kieserite, an evaporite mineral also found on Earth. Through analysis of the M.RO. HiRISE (Mars Reconnaissance Orbiter High Resolution Imaging Science Experiment images) …

Bats Of The Western Indian Ocean Islands, John O'Brien
Bats Of The Western Indian Ocean Islands, John O'Brien
KIP Articles
The natural colonisation of many remote oceanic islands by bats, including those of the western Indian Ocean, has been facilitated by their unique capability among mammals for powered flight. In the western Indian Ocean region, only the Malagasy islands of Madagascar and the Comoros archipelago have been naturally colonised by non-volant mammals. Despite their greater potential for inter-island dispersal, and thus gene transfer, endemicity of Chiroptera in the western Indian Ocean islands is high. Given their vulnerability to stochastic and anthropogenic disturbances, greater focus needs to be placed on investigating the demographic and ecological history of bats on Western Indian …

Invertebrate Fossils From Cave Sediments: A New Proxy For Pre-Quaternary Paleoenvironments, O. T. Moldovan, A. Mihevc, L. Miko
Invertebrate Fossils From Cave Sediments: A New Proxy For Pre-Quaternary Paleoenvironments, O. T. Moldovan, A. Mihevc, L. Miko
KIP Articles
Five samples of clastic sediments from interior cave facies taken in three Slovenian relic caves (Trhlovca, Račiška pečina, and a cave in Črnotiče Quarry, Classical Karst, SW Slovenia) provided invertebrate fossil remains. Most of them belong to Oribatida but sparse individuals of Cladocera and insects were also identified. They represent the first pre-Quaternary invertebrate fossils found in sediments of continental temperate climate. The Pliocene/Pleistocene age of the sediments was determined by paleomagnetic dating chronologically calibrated by micromammal biostratigraphy. Invertebrate fossils could be validated as new proxy for the study of cave sediments due to their suitability for ecological and paleogeographic …

Minerogenetic Mechanisms Occurring In The Cave Environment: An Overview, Bogdan P. Onac, Paolo Forti
KIP Articles
Perhaps man’s first motivation to explore caves, beyond using them as shelter, was the search for substances that were not available elsewhere: most of them were minerals. However, for a long time it was believed that the cave environment was not very interesting from the mineralogical point of view. This was due to the fact that most cave deposits are normally composed of a single compound: calcium carbonate. Therefore, the systematic study of cave mineralogy is of only recent origin. However, although only a limited number of natural cavities have been investigated in detail, about 350 cave minerals have already …
The Reality Of Neandertal Symbolic Behavior At The Grotte Du Renne, Arcy-Sur-Cure, France, François Caron, Francesco D'Errico, Pierre Del Moral
The Reality Of Neandertal Symbolic Behavior At The Grotte Du Renne, Arcy-Sur-Cure, France, François Caron, Francesco D'Errico, Pierre Del Moral
KIP Articles
The question of whether symbolically mediated behavior is exclusive to modern humans or shared with anatomically archaic populations such as the Neandertals is hotly debated. At the Grotte du Renne, Arcy-sur-Cure, France, the Châtelperronian levels contain Neandertal remains and large numbers of personal ornaments, decorated bone tools and colorants, but it has been suggested that this association reflects intrusion of the symbolic artifacts from the overlying Protoaurignacian and/or of the Neandertal remains from the underlying Mousterian. We tested these hypotheses against the horizontal and vertical distributions of the various categories of diagnostic finds and statistically assessed the probability that the …
Changes In Body Condition Of Hibernating Bats Support The Thrifty Female Hypothesis And Predict Consequences For Populations With White-Nose Syndrome, Kristin A. Jonasson, Craig K. R. Willis
Changes In Body Condition Of Hibernating Bats Support The Thrifty Female Hypothesis And Predict Consequences For Populations With White-Nose Syndrome, Kristin A. Jonasson, Craig K. R. Willis
KIP Articles
White-nose syndrome (WNS) is a new disease of bats that has devastated populations in eastern North America. Infection with the fungus, Geomyces destructans, is thought to increase the time bats spend out of torpor during hibernation, leading to starvation. Little is known about hibernation in healthy, free-ranging bats and more data are needed to help predict consequences of WNS. Trade-offs presumably exist between the energetic benefits and physiological/ecological costs of torpor, leading to the prediction that the relative importance of spring energy reserves should affect an individual's use of torpor and depletion of energy reserves during winter. Myotis lucifugus mate …

Transport rates and residence time in the subsurface are critical parameters for understanding water‐rock interactions for efficient contaminant remediation. This paper presents a methodology for assessing flow and transit time of water through hydrological systems, with specific applications to karst systems and implication for hydraulics of a conduit system surrounded by a porous and permeable intergranular matrix. A time variant cross‐correlation function analysis is applied to bivariate time series that characterize mass transfer, assuming a stationary system using sliding windows of various sizes. We apply the method to 1 year long temperature records in the Santa Fe River (north central …
Pan-European Distribution Of White-Nose Syndrome Fungus (Geomyces Destructans) Not Associated With Mass Mortality, Sebastien J. Puechmaille, Gudrun Wibbelt, Vanessa Korn
Pan-European Distribution Of White-Nose Syndrome Fungus (Geomyces Destructans) Not Associated With Mass Mortality, Sebastien J. Puechmaille, Gudrun Wibbelt, Vanessa Korn
KIP Articles
The dramatic mass mortalities amongst hibernating bats in Northeastern America caused by “white nose-syndrome” (WNS) continue to threaten populations of different bat species. The cold-loving fungus, Geomyces destructans, is the most likely causative agent leading to extensive destruction of the skin, particularly the wing membranes. Recent investigations in Europe confirmed the presence of the fungus G. destructans without associated mass mortality in hibernating bats in six countries but its distribution remains poorly known. We collected data on the presence of bats with white fungal growth in 12 countries in Europe between 2003 and 2010 and conducted morphological and genetic analysis …

RIDA®COUNT test plates were used as an easy-to-handle and rapid indicator of microbial counts in karst ecosystems of several caves in Slovakia and Slovenia. All of the caves had a high organic input from water streams, tourists, roosting bat colonies or terrestrial surroundings. We sampled swabs, water and air samples to test robustness and universality of the RIDA®COUNT test kit (R-Biopharm AG, Germany, http://www.r-biopharm.com/) for quantification of total bacteria, coliforms, yeast and mold. Using data from swabs (colony-forming units per cm2) we proposed a scale for description of biocontamination level or superficial microbial load of cave niches. Based on this …
