    • Bioactive Compounds from Marine Heterobranchs 

      Avila, Conxita; Angulo-Preckler, Carlos (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-21)
      The natural products of heterobranch molluscs display a huge variability both in structure and in their bioactivity. Despite the considerable lack of information, it can be observed from the recent literature that this group of animals possesses an astonishing arsenal of molecules from different origins that provide the molluscs with potent chemicals that are ecologically and pharmacologically ...

    • Epiphytic diatom community structure and richness is determined by macroalgal host and location in the South Shetland Islands (Antarctica) 

      Burfeid-Castellanos, Andrea M.; Martín-Martín, Rafael P.; Kloster, Michael; Preckler, Carlos Angulo; Avila, Conxita; Beszteri, Bank (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-30)
      The marine waters around the South Shetland Islands are paramount in the primary production of this Antarctic ecosystem. With the increasing effects of climate change and the annual retreat of the ice shelf, the importance of macroalgae and their diatom epiphytes in primary production also increases. The relationships and interactions between these organisms have scarcely been studied in Antarctica, ...

    • Experimental evidence of antimicrobial activity in Antarctic seaweeds: ecological role and antibiotic potential 

      Martín-Martín, Rafael P.; Carcedo-Forés, Marta; Camacho-Bolós, Pablo; García-Aljaro, Cristina; Preckler, Carlos Angulo; Avila, Conxita; Lluch, Jordi Rull; Garreta, Amelia Gómez (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-25)
      Seaweeds contain a wide range of secondary metabolites which serve multiple functions, including chemical and ecological mediation with microorganisms. Moreover, owing to their diverse bioactivity, including their antibiotic properties, they show potential for human use. Nonetheless, the chemical ecology of seaweeds is not equally understood across different regions; for example, Antarctic seaweeds ...

    • A Minireview on Biodiscovery in Antarctic Marine Benthic Invertebrates 

      Avila, Conxita; Preckler, Carlos Angulo (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-21)
      Antarctic marine benthic invertebrates are an underexplored source of natural products for biodiscovery. Bioactive marine natural products from Antarctica are reviewed here for their potential use as drugs, considering the main examples in Porifera (15 species), Cnidaria (eight species), Mollusca (one species), Bryozoa (one species), Nemertea (one species), Echinodermata (six species), and ...

    • Spatio-temporal patterns of eukaryotic biodiversity in shallow hard-bottom communities from the West Antarctic Peninsula revealed by DNA metabarcoding 

      Preckler, Carlos Angulo; Turon, Marta; Præbel, Kim; Avila, Conxita; Wangensteen, Owen S. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-05)
      Aim: We studied molecular eukaryotic biodiversity patterns in shallow hard-bottom Antarctic benthic communities using community DNA metabarcoding. Polar ecosystems are extremely exposed to climate change, and benthic macroinvertebrate communities have demonstrated rapid response to a range of natural and anthropogenic pressures. However, these rich and diverse ecosystems are poorly studied, ...

    • Volcanism and rapid sedimentation affect the benthic communities of Deception Island, Antarctica 

      Preckler, Carlos Angulo; Pernet, Philippe; García-Hernández, Cristina; Kereszturi, Gabor; Álvarez-Valero, Antonio M.; Hopfenblatt, Joaquín; Gómez-Ballesteros, María; Otero, Xosé L.; Caza, Jaime; Ruiz-Fernández, Jesús; Geyer, Adelina; Avila, Conxita (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-17)
      Deception Island is amongst the most active volcanoes in the Southern Ocean, with over 20 explosive eruptions in the last ca. 200 years. The eruption that formed the caldera at Deception Island occurred 3980 ± 125 calendar years Before Present, and it is the largest eruptive event documented in Antarctica during Holocene. Since then, post-caldera volcanic activity has comprised many scattered eruptive ...
