Root traits and resource acquisition determining durum wheat performance under Mediterranean conditions: An integrative approach
Crop performance is very dependent on roots because they determine the capture of water and nutrients, and the crop’s subsequent growth and productivity. Durum wheat is a major crop in the Mediterranean region, where water ...
Notes fitocenologiques IV
En connexion avec un travail monographique sur la vallée de Ribes (Pyrénées orientales), l'auteur décrit huit associations nouvelles: Veronico (urticifoliae)-Betuletum, forêt acidophile et hygrophile propre aux versants ...
Interactive effects of elevated [CO2] and water stress on physiological traits and gene expression during vegetative growth in four durum wheat genotypes
The interaction of elevated [CO2] and water stress will have an effect on the adaptation of durum wheat to future climate scenarios. For the Mediterranean basin these scenarios include the rising occurrence of water stress ...
Experimental evidence of synergistic effects of warming and invasive algae on a temperate reef-builder coral
In the current global climate change scenario, stressors overlap in space and time, and knowledge on the effects of their interaction is highly needed to understand and predict the response and resilience of organisms. ...
La necròpolis medieval de St. Martí Xic (Masies de Voltregà, Osona)
La petita església romànica de Sant Martí Xic es troba al peu del recinte del castell de Voltregà, el qual queda situat dalt d'un massís, al cantó de ponent de la plana de Vic, sobre el nucli de població de Santa Cecília ...
Twenty years, eight legs, one concept: describing spider biodiversity in Zootaxa (Arachnida: Araneae)
Zootaxa published more than a thousand papers on Araneae from 2002 to the present, including descriptions of 3,833 new spider species and 177 new genera. Here we summarise the key contributions of Zootaxa to our current ...
Polymorphisms of two loci at the oxytocin receptor gene in populations of Africa, Asia and South Europe
Background: The oxytocin (OT) system is known to be implicated in the regulation of complex social behavior, particularly empathy and parenting. The goal of this study was to estimate the gender and population differences ...

The structure of Mediterranean rocky reef ecosystems across environmental and human gradients, and conservation implications
Historical exploitation of the Mediterranean Sea and the absence of rigorous baselines makes it difficult to evaluate the current health of the marine ecosystems and the efficacy of conservation actions at the ecosystem ...
An evaluation of whale skin differences and its suitability as a tissue for stable isotope analysis
Stable isotope analysis of whale skin has been recurrently used to assess diet and movement patterns. Such studies rely on the untested assumption that the stable isotope ratios in the small skin biopsies analysed are ...
Carbon Isotope Composition and the NDVI as Phenotyping Approaches for Drought Adaptation in Durum Wheat: Beyond Trait Selection
High-throughput phenotyping platforms provide valuable opportunities to investigate biomass and drought-adaptive traits. We explored the capacity of traits associated with drought adaptation such as aerial measurements of ...
Examining the temporal effects of wildfires on forest birds: Should I stay or should I go?
In flammable ecosystems, forest dynamics are affected by fire suppression, climate change and changes in land use that cause the frequency and intensity of fires to diverge from natural fire regimes. Although afforestation ...
Crecimiento estacional y caída de acículas en Pinus uncinata Ram. y Pinus sylvestris L.
En este trabajo se estudia la formación mensual del anillo del tronco, la caída de acículas y la elongación de las ramas en poblaciones de Pinus sylvestris L. y Pinus uncinata Ram. en el Pirineo Central Español durante ...
Synergus brevis (Weld, 1962), una nova sinonímia de S. mexicanus Gillette, 1896 (Hym., Cynipidae: Synergini)
Espècie originalment descrita en el gènere Saphonecrus Dalla Torre & Kieffer, 1910, atès que tenia la cel·la radial oberta (Weld, 1926), ha estat recentment transferida al gènere Synergus Hartig, 1840 per Schwéger et al. (2015).
Multiple cotrols of community structure and dynamics in a sublittoral marine environment
The structure and dynamics of ecological communities can be determined by both top‐down (e.g., predation) and bottom‐up (e.g., energy inputs) processes, which can act synergistically and across spatial and temporal scales. ...
Understanding oceanic migrations with intrinsic biogeochemical markers
Migratory marine vertebrates move annually across remote oceanic water masses crossing international borders. Many anthropogenic threats such as overfishing, bycatch, pollution or global warming put millions of marine ...
Leaf orientation as part of the leaf developmental program in the semi-deciduous shrub, Cistus albidus l.: Diurnal, positional, and photoprotective effects during winter
Mediterranean ecosystems harbor a very important part of Earth's biodiversity, and they are a conservation priority due to the effects of global change. Here, we examined the performance of the semi-deciduous shrub Cistus ...
Biomonitoreo de la calidad del agua en los ríos ibéricos: lecciones aprendidas.
Los autores resumen en un decálogo la experiencia de más de 30 años de estudio de los ríos españoles con dos focos principales: el uso de macroinvertebrados para la obtención de la calidad biológica y el diseño de sistemas ...
Notas sobre la vegetacion del valle de Ribes
El valle de Ribes, situado en el extremo interior de los Pirineos orientales, representa una zona de transición entre las comarcas lluviosas del nordeste de Cataluña y el país relativamente seco y continental que se extiende ...
