Evidence for long-term uplift on the Canary Islands from emergent Mio-Pliocene littoral deposits

[EN] Several islands in the Canarian archipelago show marine deposits with identical fossil faunas, which are generally assigned to different glacioeustatic marine episodes: mainly Pleistocene episodes in Lanzarote and Fuerteventura, and Mio-Pliocene ones in Gran Canaria. Three fossil species (Saccostrea chili, Nerita emiliana and Strombus coronatus) characterize all the marine deposits from southern Lanzarote, to the west and south of Fuerteventura and northeast of Gran Canaria. Three other species (Ancilla glandiformis, Rothpletzia rudista and Siderastraea miocenica) confirm the chronostratigraphic attribution of these deposits. Other more occasional fossils (as Chlamys latissima, Isognomon soldanii and Clypeaster aegyptiacus) fit an upper Miocene and lower Pliocene age.

Complex organochlorine pesticide mixtures as determinant factor for breast cancer risk: a population-based case–control study in the Canary Islands (Spain)

[EN]All the relevant risk factors contributing to breast cancer etiology are not fully known. Exposure to organochlorine pesticides has been linked to an increased incidence of the disease, although not all data have been consistent. Most published studies evaluated the exposure to organochlorines individually, ignoring the potential effects exerted by the mixtures of chemicals.

Recovery plan for the giant lizard of El Hierro (Canary Islands), Gallotia simonyi: project outline and preliminary results

[EN] The Giant Lizard of El Hierro, Gallotia simonyi is one of the most endangered reptile species of the world (Corbett 1989, 1993, Machado et al. 1985). The first scientific news about a living population of G. simonyi dates back to 1975 (Böhme & Bings 1975, 1977; see also Bischoff et al. 1979). The giant lizard, widely distributed in El Hierro in the past (Böhme et al. 1981) is presently restricted to a small area of the Fuga de Gorreta (fig. 1).

A new giant land tortoise from the Pliocene of Gran Canaria (Canary Islands)

[ES] Una nueva especie de tortuga terrestre extinguida en el Plioceno de Gran Canana es descrita con el nombre de Geochelone vulcanica. La comparación con el material óseo similar de G. burchardi en la isla de Tenerife, demuestra las grandes diferencias existentes entre ambos taxones. Los huevos fósiles de tortugas terrestres descritos en la isla de Gran Canana se consideran pertenecientes a la nueva especie.

Origin, colonization, adaptive radiation, intrainsular evolution snd species substitution processes in the fossil and living lizards of the Canary Islands

[EN] The Canary lsland lizards constitute a monophyletic group which separated from the rest of the family shortly after the first islands of the archipelago emerged. Five living and at least one recently extinct species belong to the genus Gallotia. In addition, two of the living species, Gallotia simonyi and Gallotia stehlini have become extinct on Gomera and Tenerife, respectively. Juveniles of all species present tricuspid teeth. This character is preserved in the adults with changes to one degree or another in G. galloti, G. caesaris, G. simonyi and G. goliath. In G. atlantica there are only two cuspids and G. stehlini has 4 or more.

Estimating Natural Recharge by Means of Chloride Mass Balance in a Volcanic Aquifer: Northeastern Gran Canaria (Canary Islands, Spain)

[EN]The chloride mass balance method was used to estimate the average diffuse groundwater recharge on northeastern Gran Canaria (Canary Islands), where the largest recharge to the volcanic island aquifer occurs. Rainwater was sampled monthly in ten rainwater collectors to determine the bulk deposition rate of chloride for the 2008–2014 period. Average chloride deposition decreases inwardly from more than 10 g·m−2 ·year−1 to about 4 g·m−2 ·year−1 . The application of the chloride mass balance method resulted in an estimated average recharge of about 28 hm3 /year or 92 mm/year (24% of precipitation) in the study area after subtracting chloride loss with surface runoff.

Comments on Uncertainty in Groundwater Governance in the Volcanic Canary Islands, Spain

[EN]The uncertainty associated with natural magnitudes and processes is conspicuous in water resources and groundwater evaluation. This uncertainty has an essential component and a part that can be reduced to some extent by increasing knowledge, improving monitoring coverage, continuous elaboration of data and accuracy and addressing the related economic and social aspects involved. Reducing uncertainty has a cost that may not be justified by the improvement that is obtainable, but that has to be known to make the right decisions. With this idea, this paper contributes general comments on the evaluation of groundwater resources in the semiarid Canary Islands and on some of the main sources of uncertainty, but a full treatment is not attempted, nor how to reduce it.

Trichogramma canariensis (Insecta: Hymenoptera: Trichogrammatidae) a parasitoid of eggs of the twinspot moth Chrysodeixis chalcites (Lepidoptera: Noctuidae) in the Canary Islands

A new species of Trichogramma Westwood (Hymenoptera: Trichogrammatidae) parasitizing eggs of the golden twin-spot moth (or tomato looper) Chrysodeixis chalcites (Esper) (Lepidoptera: Noctuidae) on banana crops in the Canary Islands, Spain, is described as Trichogramma canariensis del Pino & Polaszek, sp.n. The new species is closely related to T. brassicae Bezdenko. Limited aspects of morphology, coupled with ITS2 and COI sequences and reproductive data are presented to distinguish T. canariensis sp.n. from T. brassicae.

Herpes simplex-like infection in a bottlenose dolphin stranded in the Canary Islands

A bottlenose dolphin, stranded in the Canary Islands in 2001 exhibited non-suppurative encephalitis. No molecular detection of cetacean morbillivirus (CeMV) was found, but a herpesviral-specific band of 250 bp was detected in the lung and brain. The sequenced herpesviral PCR product was compared with GenBank sequences, obtaining 98% homology (p-distance of 0.02) with Human herpesvirus 1 (herpes simplex virus 1 or HSV-1). This is the first report of a herpes simplex-like infection in a stranded dolphin.

FOLK ELEMENTS IN TWENTIETH-CENTURY HUNGARIAN MUSIC

At the beginning of the twentieth century, composers Béla Bartók and Zoltán Kodály collected thousands of folksongs from the rural regions of Hungary. In an effort to preserve a part of their culture that they feared would be lost, they not only transcribed and catalogued these folksongs, but also incorporated the folk traditions they encountered into their own compositional style. This dissertation deals with violin music written by Bartók, Kodály and their Hungarian contemporaries that have in common the use of rhythms, modes, melodies, figurations and playing techniques sourced in folk traditions. The use of the Hungarian folk idiom in classical music was not exclusive to the twentieth century. From the late eighteenth century until the first decades of the twentieth century, composers utilized aspects of a popular eighteenth-century form of Hungarian folk music called verbunkos. What makes the use of folk music unique in the twentieth century is that, thanks to the work of Bartók and Kodály, composers found inspiration in the more authentic “peasant music.” Unlike the popular, urban verbunkos music, peasant music was the product of the more secluded village-music tradition, largely untouched by the influences of city life. In addition to stimulating a new focus on peasant music, Bartók and Kodály fully assimilated the folk idiom into their compositional toolkits, creating a new style of folk-inspired art music that influenced a generation of Hungarian composers. The new style included characteristic elements of both peasant music and the verbunkos tradition, such as ancient modes and scales, accompanimental and melodic rhythmic patterns, ornamentation, and phrase structures sourced in folk song. To demonstrate the implementation of the folk idiom by twentieth-century Hungarian composers, three recital programs were given at the University of Maryland that included works by Béla Bartók, Sándor Veress, Leo Weiner, Zoltán Kodály, Ernő Dohnányi, Zoltán Székely and György Kurtág. The works can be divided into two main categories: settings or transcriptions of folk material (e.g. Bartók’s Hungarian Folksongs) and compositions using classical forms that include the Hungarian folk idiom (e.g. Bartók’s Contrasts). Recital collaborators include Li-Tan Hsu, Evelyn Elsing, Elizabeth Brown, Shelby Sender and Samantha Angelo.

Comparative study of the epibionts on the pelagic and mature female loggerhead turtles on the Canary and Cape Verde islands

[EN] Marine turtles commonly carry diverse forms of epizoa on their shells. The occurrence of a particular species may ultimately help to clarify certain questions about sea turtle natural life history. This paper gives a detailed and comparative list of epizoic species found on two populations of macaronesian loggerheads: pelagic and juveniles living around the Canary Islands and mature females nesting in Boavista Island, Cabo Verde. For the epizoic flora, the most important genera founded is Polysiphonia (Rhodophiceae); P. carettia for the pelagics and Polysiphonia sp. for the nesting animals.

RUSSIAN THREADS: THE PRESENCE OF RUSSIAN INFLUENCES IN TWENTIETH­ CENTURY ENGLISH CELLO MUSIC

A cursory glance at cello works by English composers during the twentieth- century yields an unexpected relationship to Russian musicians, history, culture, and religion. One must wonder how this connection or "Russian thread" came to be. When considering the working relationship of Benjamin Britten and Mstislav Rostropovich, the likelihood of such a connection is tangible, since their deeply personal friendship influenced Britten's music for cello. However, what is perhaps more interesting is the emergence of connections to Russia in the works of other English composers of the twentieth-century, featuring works from 1913-1996. This project was conceived after close study and analysis of Benjamin Britten's Third Suite for Solo Cello, Op. 87 (1971). Britten's inclusion of Russian folk tunes and an Orthodox Church hymn signaled the penetrating presence of Russian elements in his works. Britten's First Suite for Solo Cello, Op. 72, Third Suite for Cello, Op. 87, and Sonata for Piano and Cello in C, Op. 65 are presented in this project. Further exploration of works for cello by English composers unveiled similar connections to Russia. The Sonata for Cello and Piano of Frank Bridge is likened to Russian romanticism and the Cello Sonata of Sergei Rachmaninoff. William Walton's Cello Concerto was written for the Russian-American cellist Gregor Piatigorsky. Wake Up ...and die is John Tavener's deeply spiritual work, which is rooted in his Russian Orthodoxy. John Ireland, influenced by models of French and Russian Impressionism, contributed works colored with Russian folk influences, of which his Piano Trio No. 2 is an example. Finally, Arnold Bax traveled to Russia as a young man and his Folk Tale and Legend Sonata are imbued with the spirit of Russian folk music and architecture. This dissertation project is comprised of three recitals featuring English works for cello connected by a "Russian Thread." All events took place on the campus of University of Maryland, College Park: Recital #1 on December 4, 2011 in the Gildenhorn Recital Hall of the Clarice Smith Performing Arts Center, Recital #2 on February 11,2012, and Recital #3 on April 15, 2012, both in the Ulrich Recital Hall.

A unusual pinnotherid zoea attributed to Afropinnotheres monodi Manning, 1993 (Decapoda: Brachyura: Pinnotheridea) from the Selvagens Islands (Eastern Atlantic Ocean)

A pinnotherid zoea taken in a plankton sample from the Selvagens Islands during the TFMCBM/SELVAGENS’2000 Cruise, organized by the Natural Sciences Museum of Tenerife (Canary Islands), differs from previously described zoeas of the family. The specimen has dorsal and lateral spines but no rostrum, a combination of characters not previously described from pinnotherid zoeas. The lateral spines originate behind the upper part of the eye, unlike all previously described Pinnotheridae zoeas where these spines, when present, originate near the ventrolateral margin of the carapace. The specimen is attributed to Afropinnotheres monodi, the only pinnotherid species known from the area with undescribed larvae.
