  1. Definition of Microclimatic Conditions in a Karst Cavity: Rull Cave (Alicante, Spain)

    Pla, Concepción; Galiana-Merino, J.; Cuevas-González, J.; Andreu, J. M.; Cañaveras, Juan Carlos; Cuezva, Soledad; Fernández Cortés, Ángel; García-Antón, E.; Sánchez Moral, Sergio; Benavente, David
    Rull Cave (Alicante, SE Spain) is a shallow karstic cavity located in metre-thick beds of Miocene limestone conglomerate and overlain by soil with little profile development. A microenvironmental monitoring system was installed in order to record the exchange between the cave and the external atmosphere. Data were collected every 15 min over a period of 14 months (from 22/11/2012 to 13/01/2014). Both radon and CO2 concentration values changed over the course of the annual cycle and were strongly controlled by the difference in air temperature between the exterior and the cave atmosphere. Wavelet transform was applied to the data to...

  2. Nd-YAG laser irradiation damages to Verrucaria nigrescens

    Speranza, Mariela; Sanz, M.; Oujja, M.; Ríos, Asunción de los; Wierzchos, Jacek; Pérez-Ortega, Sergio; Castillejo, Marta; Ascaso, Carmen
    Epilithic and endolithic microorganisms and lichens play an important role in stone biodeterioration. The structural and physiological damage caused by nanosecond pulsed laser of 1064 nm from Nd:YAG laser to Verrucaria nigrescens lichen as well as to endolithic algae and fungi were investigated in the present study. Ultrastructural laser effects on lichen and endolithic microorganisms were study without disturbing the relationship between lichen and lithic substrate by taking lichen-containing rock fragments and processing both together. SEM-BSE, LT-SEM and FM were used to determine cell integrity and ultrastructure, which reflect microorganism viability. Photobiont vitality was determined using a PAM chlorophyll fluorescence...

  3. New data on the Moschidae (Mammalia, Ruminantia) from the upper Miocene of Spain (Mn 10–Mn 11) New data on the Moschidae (Mammalia, Ruminantia) from the upper Miocene of Spain (Mn 10–Mn 11)

    Sánchez, Israel Miguel; Domingo, M. Soledad; Morales, Jorge
    New data on the last representatives of the Spanish Miocene Moschidae (Mammalia, Ruminantia) are presented and discussed. A new species of Micromeryx, Micromeryx soriae, is described on the basis of fossil material from the locality of La Roma-2 (upper Vallesian; MN 10, Teruel province, Spain, previously assigned to Micromeryx sp.), Batallones-1, and Batallones-10 (upper Vallesian; local zone J, MN 10, Madrid province, Spain). The new species is characterized by possessing relatively hypsodont lower molars of advanced morphology and a unique type of Palaeomeryx-fold. M. soriae gives insight to the last representatives of the genus, which achieved an overall lower molar...

  6. Development and characterization of twelve new polymorphic microsatellite loci in the Iberian ribbed newt, Pleurodeles waltl (Caudata: Salamandridae), with data on cross-amplification in P. nebulosus

    Gutiérrez-Rodríguez, Jorge; González, Elena G.; Martínez-Solano, Íñigo
    Twelve novel polymorphic microsatellite loci were isolated and characterized for the Iberian ribbed newt, Pleurodeles waltl (Caudata, Salamandridae). The distribution of this newt ranges from central and southern Iberia to northwestern Morocco. Polymorphism of these novel loci was tested in 40 individuals from two Iberian populations and compared with previously published markers. The number of alleles per locus ranged from two to eight. Observed and expected heterozygosity ranged from 0.13 to 0.57 and from 0.21 to 0.64, respectively. Cross-species amplification was tested in Pleurodeles nebulosus, which is listed as Vulnerable by the IUCN. Eight new and seven previously published loci...

  7. Mortality patterns and skeletal physical condition of the carnivorans from the Miocene assemblage of Batallones-1 (Madrid Basin, Spain)

    Domingo, M. Soledad; Alberdi, María Teresa; Azanza, Beatriz; Morales, Jorge
    Batallones-1 lower level assemblage contains numerous and diverse Miocene vertebrates that were deposited over time at the bottom part of a cavity. In this study, the age structure and skeletal physical condition of the four more abundant taxa, all of them carnivorans, are analysed to better delineate the taphonomic history undergone by the remains and the concentration mode of the assemblage. The prime-adult dominated profile of the two sabertoothed cats and the hyaenid can be related to a proneness of these individuals to search for resources in dangerous locations during the stressful period of dispersal. In turn, the amphicyonid profile,...

  8. Origin of an Assemblage Massively Dominated by Carnivorans from the Miocene of Spain

    Domingo, M. Soledad; Alberdi, María Teresa; Azanza, Beatriz; Silva, Pablo G.; Morales, Jorge
    Carnivoran-dominated fossil sites provide precious insights into the diversity and ecology of species rarely recovered in the fossil record. The lower level assemblage of Batallones-1 fossil site (Late Miocene; Madrid Basin, Spain) has yielded one of the most abundant and diversified carnivoran assemblage ever known from the Cenozoic record of mammals. A comprehensive taphonomic study is carried out here in order to constrain the concentration mode of this remarkable assemblage. Another distinctive feature of Batallones-1 is that the accumulation of carnivoran remains took place in the context of a geomorphological landform (cavity formation through a piping process) practically unknown in...

  9. Polymorphic microsatellite markers for the critically endangered Balearic shearwater, Puffinus mauretanicus

    González, Elena G.; Genovart, Meritxell; Oro, Daniel; Zardoya, Rafael; Juste, Javier
    Ten novel polymorphic microsatellite loci were isolated and characterized from the Balearic shearwater (Puffinus mauretanicus), a critically endangered seabird. The developed loci revealed a relatively low number of alleles per locus, as well as low levels of polymorphism (HO = 0.377 ± 0.241). One of the loci appeared to be W-linked. All polymorphic loci were successfully amplified in its closely related species, the Yelkouan shearwater (Puffinus yelkouan). These microsatellite markers would be useful for assessing population structure in the Balearic shearwater and the possible hybridization process between both shearwaters species

  10. Two pieces of information in a single trait? The yellow breast of the great tit (Parus major) reflects both pigment acquisition and body condition

    Senar, Juan Carlos; Negro, Juan J.; Quesada, Javier; Ruiz, Iker; Garrido Fernández, J.
    Carotenoid-based plumage coloration has been shown to be dependent both on pigment content and feather structure. Against this background, we predict a relationship between feather pigment content and plumage hue. Furthermore, given the susceptibility of chroma to developmental perturbation of feather structure, we predict body condition to be related to chroma. We tested these predictions in the great tit, Parus major. Carotenoid content in yellow breast feathers was analysed by high-performance liquid chromatography (HPLC). Lutein was the main carotenoid contained in great tit feathers, followed by zeaxanthin. The hue of the feathers was accurately predicted from their lutein concentration, and chroma was predicted from the body condition value....

  11. New evidence for the reawakening of Teide volcano

    Gottsmann, Joachim; Wooller, Luke K.; Martí Molist, Joan; Fernández Torres, José; Camacho, Antonio G.; González Méndez, Pablo José; García García, Alicia; Rymer, Hazel
    Geophysical signals accompanying the reactivation of a volcano after a period of quiescence must be evaluated as potential precursors to impending eruption. Here we report on the reactivation of the central volcanic complex of Tenerife, Spain, in spring 2004 and present gravity change maps constructed by time-lapse microgravity measurements taken between May 2004 and July 2005. The gravity changes indicate that the recent reactivation after almost a century of inactivity was accompanied by a sub-surface mass addition, yet we did not detect widespread surface deformation. We find that the causative source was evolving in space and time and infer fluid migration at depth as the most likely cause for mass increase. Our...

  13. The role of immigration and local adaptation on fine-scale genotypic and phenotypic population divergence in a less mobile passerine

    García-Navas, Vicente; Ferrer, Esperanza S.; Sanz, Juan José; Ortego, Joaquín
    Dispersal and local patterns of adaptation play a major role on the ecological and evolutionary trajectory of natural populations. In this study, we employ a combination of genetic (25 microsatellite markers) and field-based information (seven study years) to analyse the impact of immigration and local patterns of adaptation in two nearby (< 7 km) blue tit (Cyanistes caeruleus) populations. We used genetic assignment analyses to identify immigrant individuals and found that dispersal rate is female-biased (72%). Data on lifetime reproductive success indicated that immigrant females produced fewer local recruits than their philopatric counterparts whereas immigrant males recruited more offspring than those that...

  14. A 2,500-year multi-proxy reconstruction of climate change and human activities in northern Spain: the Lake Arreo record

    Corella, Juan Pablo; Stefanova, Vania; El Anjouni, Adel; Rico, Eugenio; Giralt, Santiago; Moreno Caballud, Ana; Plata-Montero, Alberto; Valero-Garcés, Blas L.
    Lake Arreo sequence (western Ebro Basin, Spain) illustrates the century-scale climatic variability and human interactions in the landscape during the last 2.5 kyr in the low lands of northern Spain. Two sediment cores from shallow-water and deep-water environments were analyzed using sedimentological, geochemical, mineralogical, biological ¿ diatoms, pollen and charcoal content ¿ and radiometric techniques for absolute dating. The shallow-water sequence indicates a rapid evolution from an alluvial-influenced wetland prior to 7th century BC to a wetland during the Ibero-Roman Humid Period (BC 630¿AD 465) and a deeper, carbonate producing lake during the Dark Ages Cold Period (AD 465¿890). The...

  15. Lacustrine carbonates of Iberian Karst Lakes: Sources, processes and depositional environments

    Valero-Garcés, Blas L.; Morellón, Mario; Moreno Caballud, Ana; Corella, Juan Pablo; Martín-Puertas, Celia; Barreiro-Lostres, Fernando; Pérez-Sanz, Ana; Giralt, Santiago; Mata, M. Pilar
    [EN] Carbonates are the main components of Iberian Quaternary lake sediments. In this review we summarize the main processes controlling carbonate deposition in extant Iberian lakes located in Mesozoic and Tertiary carbonate-dominated regions and formed through karstic activity during the Late Quaternary. The lakes, relatively small (1 ha to 118 ha) and relatively shallow (Zmax = 11 to 40 m) provide examples of the large variability of sedimentary facies, depositional environments, and carbonate sources. Hydrology is dominated by groundwater inflow except those directly connected to the fluvial drainage. Nine lakes have been selected for this review and the main facies...

  17. Mud-Ball construction by sceliphron Mud-Dauber wasps (Hymenoptera: Sphecidae): A comparative ethological study

    Chatenoud, L.; Polidori, Carlo; Federici, M.; Licciardi, V.; Andrietti, F.
    Mud-ball construction by Sceliphron mud-dauber wasps (Hymenoptera: Sphecidae): a comparative ethological study. Zoological Studies 51(7): 937-945. Mud-dauber wasps of the genus Sceliphron build aerial nests using mud collected at humid-soil sources and carried to the nest in the form of spherical mud-balls. We recorded and analyzed a series of video-sequences of 5 (3 native and 2 alien) species of Sceliphron in Italy, in order to compare their mud-ball-building behavior. Four phases were recognized: I) patrolling the ground in search of a suitable place for mud-ball building; II) removing leafs, twigs, or small stones from the chosen area; III) forming the...

  18. Hatching asynchrony and brood reduction influence immune response in Common Kestrel Falco tinnunculus nestlings

    Martínez-Padilla, Jesús; Viñuela, Javier
    The onset of incubation before the end of laying imposes asynchrony at hatching and, therefore, a size hierarchy in the brood. It has been argued that hatching asynchrony might be a strategy to improve reproductive output in terms of quality or quantity of offspring. However, little is known about the mediating effect of hatching asynchrony on offspring quality when brood reduction occurs. Here, we investigate the relationship between phenotypic quality and hatching asynchrony in Common Kestrel Falco tinnunculus nestlings in Spain. Hatching asynchrony did not increase breeding success or nestling quality. Furthermore, hatching asynchrony and brood reduction had different effects...

  19. Mineralogy, geochemistry and uses of the mordenite-bentonite ash-tuff beds of Los Escullos, Almería, Spain

    Benito García, R.; García-Guinea, Javier; Valle Fuentes, Francisco José; Recio, Paloma
    The mordenite ore deposit of Los Escullos has a surface area of 106 m2 with an average thickness of 5 m and estimated reserves of 7,500,000 tons of mordenite-bentonite. It is made up of horizontal layers of interbedded epiclastic tuffs with volcanic bentonitised materials which have been subjected to hydromagmatic activity. The layers are essentially composed of bentonite and mordenite with lesser amounts of quartz, cristobalite, biotite, plagioclase, chlorite, amphiboles, titanomagnetite, ilmenite and calcite. The harder layers display a higher proportion of plagioclase crystals and are enriched in Al2O3, CaO, Fe2O3, TiO2, P2O5, Cu, Zn, Co, Cr, Ni and V,...

  20. A new genus and a new species of hydrobiid snail (Mollusca: Gastropoda: Hydrobiidae) from Eastern Spain

    Ramos, M. Ángeles; Arconada, Beatriz; Moreno, D.
    The identity of Hauffenia (Neohoratia) gasulli Boeters, in Gasull, 1981, type material, with shell topotypes and live specimens collected in neighbouring localities, has been established on the basis of shell characters (statistical analysis DFA and Anova). Anatomical studies confirmed its allocation to a new genus, Tarraconia, which is only known from the Iberian Peninsula. We present histological data to demonstrate the lack of a seminal receptacle, its function having being transferred to a wide part of the proximal renal oviduct. This character, together with a well-defined data set, including lack of a suboesophageal connective and a gastric caecum, penis size...
