From glacial echoes to timber pathways: Climatic–historical drivers and timber‐trade influence on the phylogeography of Ips sexdentatus in the Basque Country

open access: yesAgricultural and Forest Entomology, EarlyView.
Ips sexdentatus is expanding across southern Europe, attacking multiple Pinus species and showing the ability to colonize trees at early stages of decline. Genetic analysis of 668 individuals revealed 106 haplotypes, with Iberian populations as diversity hotspots, reflecting long‐term refugial persistence alongside more recent demographic expansion ...

Mapping Palaeolithic Imprints: Spatial Analysis of Hand Stencils in El Castillo Cave (Spain) Through Geomatic Techniques

open access: yesArchaeometry, EarlyView.
ABSTRACT We present the application of a new quantitative approach to space study in Palaeolithic cave art. Using GIS, we analysed the distribution and position of hand stencils in El Castillo cave to track the gestures and behaviours of Palaeolithic societies.

New 3-Hydroxyquinaldic Acid Derivatives from Cultures of the Marine Derived Actinomycete Streptomyces cyaneofuscatus M-157

open access: yesMarine Drugs, 2018
Fractionation of the bioactive extract of a culture of the marine derived actinomycete Streptomyces cyaneofuscatus M-157 led to the isolation of the known 3-hydroxyquinaldic acid (4), its amide (5) and three new derivatives (1–3) containing ...

Worldwide Impact of Human Development and Inequality on the Prevalence of Asthma, Rhinoconjunctivitis and Eczema. Global Asthma Network's Ecological Study

open access: yesClinical &Experimental Allergy, EarlyView.
Global Asthma Network Phase I surveyed children, adolescents, and adults worldwide to assess the prevalence of asthma, rhinoconjunctivitis, and eczema. Human Development Index (HDI) and Gini inequality index (GinI) were important explanatory factors for prevalence variability of these conditions, with hotspots in areas with high HDI and high GinI ...

A histology-free description of Lineus marcosii (Pilidiophora: Lineidae), a cryptic species resembling Lineus lacteus

open access: yesZoologia (Curitiba)
Cryptic biodiversity is one of the main challenges to overcome for an accurate characterization of Earth’s biodiversity. The nemertean species Lineus lacteus has been recorded from Sweden to the Black Sea since its description in the first half of the ...

Anthracimycin B, a Potent Antibiotic against Gram-Positive Bacteria Isolated from Cultures of the Deep-Sea Actinomycete Streptomyces cyaneofuscatus M-169

open access: yesMarine Drugs, 2018
The potent antimicrobial extract of a culture of the marine derived actinomycete Streptomyces cyaneofuscatus M-169 was fractionated by reversed phase flash chromatography and preparative HPLC to yield the new Gram-positive antibiotic, anthracimycin B (1),

Beyond the breeding grounds: identifying post‐breeding staging areas, corridors and ecological niche of the Lesser Kestrel

open access: yesIbis, EarlyView.
The post‐breeding period is a critical yet overlooked phase in the annual cycle of migratory birds, where individuals must resolve competing bioenergetic trade‐offs between recovery from breeding, moult and migratory fuelling. Using GPS data from 54 adult Lesser Kestrels Falco naumanni tracked across Spain, we analysed 76 post‐breeding tracks to ...

Morphological and genetic diversity of the wood-boring Xylophaga (Mollusca, Bivalvia): new species and records from deep-sea Iberian canyons. [PDF]

open access: yesPLoS ONE, 2014
Deep-sea bivalves of the Xylophagaidae, a poorly known group, are obligate wood-borers. Deployment of wood in three submarine canyons off the Iberian coast, the Blanes and La Fonera Canyons (Mediterranean Sea) and the Avilés Canyon (Cantabric Sea, Bay of

When Infrastructure Pushes Residents Out: High‐Speed Rail and Tourism Outflows

open access: yesJournal of Regional Science, EarlyView.
ABSTRACT This paper examines the impact of high‐speed rail (HSR) connectivity on both inbound and outbound tourism inflows. Leveraging the opening of a new HSR line connecting a northern Spanish region with mainland Spain, we employ a triple difference‐in‐differences design combined with inverse probability weighting (IPW) to evaluate the causal effect
