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. ...

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 ...
