Asociaciones de Ostrácodos del Mioceno Temprano—Medio de Loma Negra (Bardenas Reales de Navarra, Cuenca del Ebro): Evolución Paleoambiental de un Med…

LOWER-MIDDLE MIOCENE OSTRACOD ASSEMBLAGES OF LOMA NEGRA (BARDENAS REALES DE NAVARRA, EBRO BASIN): PALAEOENVIRONMENTAL EVOLUTION OF A LACUSTRINE SYSTEM. The palaeoenvironmental evolution of the Loma Negra section (Bardenas Reales de Navarra, Ebro Basin) during the lower-middle Miocene, is studied for the first time. The paleoen- vironmental interpretation is based on the recovered ostracod assemblages and the sedimentology. The lower part of this section is composed by red, yellow and grey mudstones, and with Paralimnocythere sp. as the most abundant ostracod taxon. The lithological features and the fau- nistic assemblage allows the interpretation of a paleoenvironment with the development o…

<strong>A new species of <em>Pactola</em> Pascoe, 1876 (Coleoptera: Curculionidae: Eugnomini) from New Caledonia</strong>

2015

Pactola corporosa sp. n. is described from New Caledonia. Illustrations of body parts, terminalia of both sexes and distributional data of the new species are provided. The genus Pactola Pascoe, 1876 now contains thirteen species distributed in New Zealand, New Caledonia and Taevuni Island (Fiji Archipelago).

A NEW SPECIES OF ANTRUSA AND THREE NEW SPECIES OF CHOREBUS (HYMENOPTERA: BRACONIDAE) FROM THE IBERIAN PENINSULA

2004

Antrusa curtitempus, Chorebus liliputanus, C. propediremptum, and C. vicinus, four new species of Dacnusini from the Iberian Peninsula, are described, illustrated, and compared with allied species. Keys for their discrimination are provided. The taxonomic rehabilitation of the genus Antrusa is proposed.

A multi-gene approach reveals a complex evolutionary history in the Cyanistes species group

2011

Quaternary climatic oscillations have been considered decisive in shaping much of the phylogeographic structure around the Mediterranean Basin. Within this paradigm, peripheral islands are usually considered as the endpoints of the colonization processes. Here, we use nuclear and mitochondrial markers to investigate the phylogeography of the blue tit complex (blue tit Cyanistes caeruleus, Canary blue tit C. teneriffae and azure tit C. cyanus), and assess the role of the Canary Islands for the geographic structuring of genetic variation. The Canary blue tit exhibits strong genetic differentiation within the Canary Islands and, in combination with other related continental species, provides a…

El género <i>Lysaphidus</i> (Hymenoptera: Braconidae) en la Península Ibérica

1995

The genus Lysaphidus Smith, 1944 (Hymenoptera, Braconidae, Aphidiinae) is recorded for the first time from the Iberian Peninsula represented by two species: L. arvensis Stary, 1960, first record for the Iberian Peninsula, and L. santolinae n. sp., both of them parasitoids of Coloradoa Wilson,1910 genus (Homoptera, Aphididae). The mummies were collected on Santolina chamaecyparissus L. and Santolina rosmarinifolia L. (Asteraceae).

Activity overlap between mesocarnivores and prey in the Central Mongolian steppe

2021

Research on the ecology and behaviour of mesocarnivores and their prey is scant in Mongolia. We investigated activity patterns of a guild of mesocarnivores (red fox, Pallas's cat and beech marten) and their prey (Siberian marmot, Daurian pika, Brandt vole, Mongolian gerbil and Mongolian silver vole) using 21 camera traps (effort = 1155 camera days) in Central Mongolia from 25st of May to 20th August 2019. Activity patterns of mesocarnivores were cathemeral (i.e. no difference between diurnal, nocturnal and crepuscular detections, although activity peaked at sunrise). Among prey, the Siberian marmot and the Daurian pika were diurnal, whereas the Mongolian gerbil and the Mongolian silver vole…

Taxonomic Revision of the Genus Trictenotoma Gray, 1832 (Coleoptera: Trictenotomidae). Part 3 – Species from the Philippine Archipelago, with Descrip…

2021

The species of Trictenotoma Grey, 1832 from the Philippine Archipelago are critically assessed, description of T. boudanti Drumont et Telnov sp. nov. from Balabac and Palawan, and a redescription of T. cindarellaKriesche, 1921 from Mindanao are provided. A key to the Philippine Trictenotomidae Blanchard, 1845 is presented for the first time.

Geochemistry of streams from Byers Peninsula, Livingston Island

2013

AbstractIn January and February 2009, a series of water samples were collected from streams on Byers Peninsula. These samples were analysed for major elements and δ18O to determine the role of lithology and landscape position on stream geochemistry, and to understand better the hydrology (i.e. residence time of water) of these systems. Precipitation chemistry is enriched in Na+, as are the streams located close to the coast. Streams originating from inland locations have much higher percentages of Ca2+. In contrast, Mg2+ varied little, though streams that are in greater contact with volcanic-derived soils have slightly higher concentrations. Anion percentages varied greatly between streams …
