Exploración de elementos de tierras raras en materiales geológicos subaéreos y submarinos de las Islas Canarias: estado de la cuestión
La exploración de mineralizaciones de tierras raras (TR) en islas volcánicas y montes submarinos del archipiélago canario se ha llevado a cabo en tres tipos de materiales geológicos: (1) rocas ígneas félsicas (traquitas, ...
Productes químics en contacte amb els insectes en el procés de preparació i conservació al Museu de Zoologia de Barcelona entre 1939 i 1989
In studies investigating heavy metal contamination in the bodies of coleopterans and lepidopterans preserved in museum collections, questions often arise about whether the source of contamination is environmental or related ...
Moult and age determination criteria of the monk parakeet (Myiopsitta monachus)
Age determination of the invasive monk parakeet Myiopsitta monachus has been hampered by its juvenile plumage showing only subtle differences from subsequent plumages, and little is known about its moult. Here we examined ...
Motivos botánicos en las artes visuales: una mirada alternativa a la flora de China
El uso de elementos vegetales (flores, hojas, frutos, pero también plantas enteras) está muy presente en las diferentes expresiones del arte visual (pintura, cerámica, escultura y arquitectura principalmente), y ...
Cataloging the alien flora of the Costa Brava (NE Iberian Peninsula): new findings and updates in a plant invasion hotspot
The Costa Brava, a Mediterranean coastal strip spanning ca. 250 km (in NE Spain), is a hotspot of plant invasions. To address this issue, the LIFE medCLIFFS project was launched to improve the management of invasive ...
Cryptic speciation in arid mountains: an integrative revision of the Pristurus rupestris species complex (Squamata, Sphaerodactylidae) from Arabia based on morphological, genetic and genomic data, with the description of four new species
In the arid landscapes of the Arabian Peninsula, high levels of cryptic diversity among reptiles, and especially in geckos, have recently been revealed. Mountain ranges within the peninsula were shown to contain the ...
Atethmia algirica (Culot, 1914-1917) a Catalunya (Lepidoptera, Noctuidae, Hadeninae) = Atethmia algirica (Culot, 1914-1917) en Catalogne (Lepidoptera, Noctuidae, Hadeninae)
Atethmia algirica (Culot, 1914-1917) es un noctuid íbero-magribí, que habita el Magrib i la península Ibèrica. L`extrem septentrional de la seva àrea de dispersió coneguda es troba situat al sud-oest de Catalunya, on ...
Erebia pronoe (Esper, 1780) a Catalunya (Lepidoptera, Nymphalidae, Satyrinae) = Erebia pronoe (Esper, 1780) en Catalogne (Lepidoptera, Nymphalidae, Satyrinae)
Es duu a terme un estudi sobre el Satyrinae Erebia pronoe (Esper, 1780) i la seva distribució a Catalunya. El tàxon ha estat trobat al Pirineu central català (comarques de la Vall d’Aran i de l’Alta Ribagorça). La seva ...
Continent-wide drivers of spatial synchrony in breeding demographic structure across wild great tit populations
Variation in age structure influences population dynamics, yet we have limited understanding of the spatial scale at which its fluctuations are synchronised between populations. Using 32 great tit populations, spanning ...
Obtaining three-dimensional models of limb long bones from small mammals: a photogrammetric approach
The use of two-dimensional (2D) pictures to analyse form variation of three-dimensional (3D) objectsentails measurement error, loss of important information and a possible misinterpretation of real shapechanges. Despite ...
Idiosyncrasy of feather mite intensity and prevalence across passerine bird species: a comparative study
Symbionts are key elements of ecosystems, by playing important roles in shaping the biology and ecology of their hosts. However, the factors determining symbiont loads across host species are still unclear. Nowadays, we ...
Documentació de la coŀlecció de Zigenes d’Esteve Bassa i Mauri (1946-2023), i aportacions faunístiques interessants (Lepidoptera: Zygaenidae)
The sudden death of Esteve Bassa has led to the transfer of the Zygaenidae that were part of his collection to the Natural Sciences Museum of Barcelona. With this donation, the conservation of the Zygaenidae is guaranteed, ...
Els lepidòpters nocturns de la finca de Can Marroig, Parc Natural de ses Salines, Formentera (illes Balears) (Insecta: Lepidoptera)
During the autumn of 2023 and the spring of 2024, a night sampling was carried out using light traps in the Ses Salines Natural Park, within the Can Marroig estate, Formentera (Balearic Islands), to learn about the ...
Imágenes 3D, una nueva colección científica en el Museu de Ciències Naturals de Barelona (MCNB)
La introducción de nuevas tecnologías en los museos es necesaria e imprescindible para su modernización. Es importante verificar previamente que éstas permitirán obtener o ampliar la rendibilidad científica y cultural del ...
The expansion of monk parakeet in mediterranean urban areas: implications for the transmission of parasites by native and invasive vectors
Invasive species may create novel epidemiological scenarios in the invaded areas by changing the transmission dynamics of pathogens. Here we test the implication of two invasive species in the ...
Un homenaje a dos pilares de la ecología evolutiva en España: Anders y Tinín
Homenaje a Anders Møller y Florentino de Lope
The winner takes it all: a single genotype of Kalanchoe ×houghtonii is a global invader
Invasive alien plant species pose a global challenge, and their impact is amplified by globalisation and the accelerating pace of climate change. In mild-climate regions, drought-tolerant invasive plants showing broad ...
Associating cultivars or species with complementary traits is key for enhancing aphid control through bottom-up effects
Organic farming promotes diversification strategies to enhance ecological functions. However, early field studies suggested that not all cereal polycultures confer benefits in terms of pest control. Our research involved ...
Petrogenesis of the alkaline lamprophyre cluster between Molí d’en Ponç and Collet de la Cidereda (eastern Catalonian Coastal Ranges, NE Iberia)
This work focuses on the cretaceous camptonite cluster between Molí d’en Ponç and Collet de la Cidereda, eastern Montseny massif from the Catalan Coastal Ranges (NE Iberian Peninsula). These post-orogenic lamprophyres (~ 79 ...
Testing for parallel genomic and epigenomic footprints of adaptation to urban life in a passerine bird
Identifying the molecular mechanisms involved in rapid adaptation to novel environments and determining their predictability are central questions in Evolutionary Biology and pressing issues due to rapid global changes. ...
