Inferring the wintering distribution of European storm petrels (Hydrobates pelagicus spp melitensis) from stable isotope analysis and observational field data
Bird migration studies have been given added impetus recently thanks to the miniaturisation of tracking devices. However, tracking methodologies have remained impractical for the smallest pelagic species and so important ...
Childhood abuse in the etiological continuum underlying psychosis from first-episode psychosis to psychotic experiences
GOAL: The present study aimed to examine the prevalence of child abuse across the continuum of psychosis. PATIENTS AND METHODS: The sample consisted of 198 individuals divided in three groups: (1) 48 FEP patients, (2) 77 ...
Tundra Trait Team: a database of plant traits spanning the tundra biome
Motivation The Tundra Trait Team (TTT) database includes field‐based measurements of key traits related to plant form and function at multiple sites across the tundra biome. This dataset can be used to address theoretical ...
High Potential of Facial Biomarkers to Diagnose Psychotic Disorders
Schizophrenia (SCZ) and Bipolar Disorder (BP) are severe psychiatric disorders (PD) that affect more than 3% of the world's population and are among the leading causes of disability worldwide. Current diagnostic systems ...
Variability of the radius growth at 25 years old Pinus uncinata Miller ex Mirbel in the North-East Spanish Pyrenees
It has been studied the variability of stem radial growth in four radius orientations at the age of 25 years old trees. The species was Pinus uncinata. The sampling sites, located in the North East Spanish Pyrenees belong ...
A new genus of oak gall wasp, Striatoandricus Pujade-Villar (Hyenoptera: Cynipidae: Cynipini) from Americ with descriptions of two new Mexican species
A new genus of cynipid oak gall wasp, Striatoandricus Pujade-Villar (Hymenoptera: Cynipidae: Cynipini), is described. Striatoandricus gen. nov. includes four previously described species, Andricus nievesaldreyi n. comb., ...
Molecular dating of caprines using ancient DNA sequences of Myotragus balearicus, an extinct endemic Balearic mammal
Background: Myotragus balearicus was an endemic bovid from the Balearic Islands (Western Mediterranean) that became extinct around 6,000-4,000 years ago. The Myotragus evolutionary lineage became isolated in the islands ...
Spore germination and development of young mycelia in some Rhizopogon species
Spore germination in Rhizopogon abietis, R. luteolus, R. roseolus and R. villosulus was induced in the presence of Rhodotorula glutinis and activated charcoal, in agar medium (N6:5). In one R. roseolus sample, 51% of spores ...
Sobre les avellanoses als Pirineus catalans
Els bosquets de Corylus avellana dels Pirineus Catalans representen, malgrat llur fisiognomía uniforme, fases de degradació o de reconstitució de diversos boscos caducifolis. Atenent a aquest fet i a llur composició ...
Deep-sea, deep-sequencing: metabarcoding extracellular DNA from sediments of marine canyons
Marine sediments are home to one of the richest species pools on Earth, but logistics and a dearth of taxonomic work-force hinders the knowledge of their biodiversity. We characterized α- and β-diversity of deep-sea ...
Algunas adventicias notables en el Euphorbieto-Eleusinetum geminatae (ass. nova) de Barcelona
Alternantherarepens (L.j Steud. ( =A. achymnthaR. Br.). Amarantácea procumbente, de hojas elíptico-orbiculares y glomérulos blanco-plateados. Fué hallada en el puerto de Barcelona, junto a las vías del ferrocarril, hacia ...
Strategic Tillage in the Mediterranean: No Universal Gains, Only Contextual Outcomes
In Mediterranean drylands, where year-to-year climatic variability and soil con-straints (e.g., compaction or shallow profiles) often limit the feasibility of strict no-tillage (NT), strategic tillage (ST) has emerged as ...
Light regime and components of turbidity in a Mediterranean coastal lagoon
The underwater light regime of a Mediterranean coastal lagoon (Albufera des Grau, Balearic Islands) was studied during four years in order to characterise the spatial and temporal variations in the light attenuation ...
The influence of visitors on behaviour and on the use of space in two species of ursids: a managenent question?
Zoos and aquariums are making significant contributions to conservation by acting as mentors in socially relevant formal and informal education, thereby influencing people's attitudes and behaviour towards animals and ...
Dendroclimatological study of Pinus sylvestris L. in southern Catalonia (Spain)
Two modern tree-ring width chronologies of Pinus sylvestris L. have been established in an area near the southern limit of the species distribution. Trees were sampled in the south of Catalonia in northeastern Spain where ...
Drought-induced weakening of growth-temperature associations in high-elevation Iberian pines
The growth/climate relationship of theoretically temperature-controlled high-elevation forests has been demonstrated to weaken over recent decades. This is likely due to new tree growth limiting factors, such as an increasing ...
Trichoptera (INSECTA) collected in Mediterranean river basins in the Iberian Peninsula: taxonomic remarks and notes on ecology
As a result of the GUADALMED project, undertaken in Iberian Mediterranean basins, to which were added samples taken by the junior author in the area, we collected numerous caddisfly larvae, pupae and adults. Some larvae ...

Parasitoids of Monochamus galloprovincialis (Coleoptera, Cerambycidae), vector of the pine wood nematode, with identification key for the Palaearctic region
The parasitoid complex associated with Monochamus galloprovincialis (Olivier), vector of the pine wood nematode, is discussed. Four species of the family Braconidae and one Ichneumonidae were found associated with Monochamus ...
High trophic niche overlap between a native and invasive mink does not drive trophic displacement of the native mink during an invasion process
The pressure elicited by invasive species on native species significantly increases with the increase of the overlap of their ecological niches. Still, the specific mechanisms of the trophic displacement of native species ...
