  • UB study analyses the structure of marine ecosystems from 6,000 to 5,000 years ago to anticipate those changes caused by global warming
    Global warming will modify the distribution and abundance of fish worldwide, with effects on the structure and dynamics of food networks. However, making precise predictions on the consequences of this global phenomenon is hard without having a wide historical perspective. A study carried out at the UB and the Southern Centre for Scientific Research (CADIC-CONICET, Argentina), analysed the potential implications in the distribution of the Argentinian hake (Merluccius hubbsi), caused by the warming of marine waters. The study is based on the analysis of the structure of the marine ecosystems from 6,000 to 500 years ago, when temperatures were warmer than now. The results show this species could expand towards south and reach the coast of the South America extreme southern area, like it happened in the past. According to the researchers, this approach allows researchers to make predictions on the transformations to be caused by the climate change in the marine environment with important ecogical and economic implications.
  • Sea slugs: discovering other inhabitants in the Barcelona coasts
    Un estudi sobre biodiversitat marina ha identificat setanta-tres espècies de llimacs de mar al litoral de la ciutat de Barcelona, un entorn fortament antropitzat per la metròpoli urbana. Segons revela un article coordinat pel professor Manuel Ballesteros, de la Facultat de Biologia i de l’Institut de Recerca de la Biodiversitat (IRBio) de la Universitat de Barcelona, en aquest grup de mol·luscos gasteròpodes, els que més abunden al litoral urbà són les llebres de mar.
  • Researchers identify a mechanism that explains the recurrence of many lung infections
    A study published in the journal Virulence states that the class II ribonucleotide reductase enzyme (RNR) plays a key role in the frequent lung reinfection processes that affect patients with cystic fibrosis, among other cases. The study is led by the experts Eduard Torrents, tenure-track 2 lecturer at the Department of Genetics, Microbiology and Statistics of the Faculty of Biology of the UB and researcher at IBEC, and Maria de la Mar Cendra, also member of IBEC.
