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. ...
Los especímenes tipo de ortópteros (Insecta, Orthoptera) del Museu de Ciències Naturals de Barcelona, España
The Orthoptera type specimens held at the Museu de Ciències Naturals de Barcelona (Natural Sciences Museum of Barcelona, MCNB) have undergone a comprehensive review and detailed documentation. The collection comprises 115 ...

Es descriu un nou moitessièrid (Gastropoda: Moitessieriidae) present a tres fonts situades al municipi de Castellar del Vallès, a partir de material conquiliològic obtingut mitjançant el triatge de sediments: Moitessieria ...
Ancient genomics: clues about the earliest migrations out of Africa
Analyses of 45,000-year-old bones from Europe allow scientists to pin down when modern humans interbred with Neanderthals, shedding light on the histories of populations with no present-day descendants.
Com fer un article divulgatiu: integrant coneixements i desenvolupant competències
Activitat dissenyada per proporcionar als estudiants uns fonaments clars per escriure bones memòries, informes o articles en el seu futur professional. Neix de la necessitat de millorar la seva competència comunicativa ...
Llista actualitzada dels microlepidòpters paleàrtics (Insecta, Lepidoptera) del Museu de Ciències Naturals de Barcelona
The microlepidoptera collection housed at the Museu de Ciències Naturals de Barcelona (the Natural Sciences Museum of Barcelona, MCNB) has been documented. The collection consists of 44 boxes with a total 7,146 specimens: ...
Nassarius acer n. sp., a new species of Nassariidae (Gastropoda, Neogastropoda) from Indo-Western Pacific
A new species of the genus Nassarius, N. acer. n. sp., from Indonesia is described. Although uncommon, specimens with this morphology were known but had never been formally described as a new species. This new species ...
Age and sex differences in niche use at molt and its effect on plumage coloration characteristics in a bird
Bird plumage is often very colorful and can communicate the quality of the bearer to conspecifics. These plumage-based signals of quality are composed of multiple pigments (e.g., melanin and carotenoids). Therefore, sex ...
Beyond 10,000 ancient human genomes: ancestral origins at the Balkans
With more than 10,000 ancient human genomes published in 2023, thanks to new technological developments on DNA sequencing, we are now able to investigate multiple ancestry layers associated to past migrations that have ...
