      Demosponges are a well-known source of a plethora of bioactive compounds. In particular, they are able to form a skeleton by direct deposition of silica in a process catalyzed by silicatein. Herein, we isolated biosilicas ...

    • Biodiversity, environmental drivers, and sustainability of the global deep-sea sponge microbiome 

      Busch, Kathrin; Slaby, Beate M.; Bach, Wolfgang; Boetius, Antje; Clefsen, Ina; Colaço, Ana; Creemers, Marie; Cristobo, Javier; Federwisch, Luisa; Franke, Andre; Gavriilidou, Asimenia; Hethke, Andrea; Kenchington, Ellen; Mienis, Furu; Mills, Sadie; Riesgo, Ana; Ríos, Pilar; Roberts, Emyr Martyn; Sipkema, Detmer; Pita, Lucía; Schupp, Peter J.; Xavier, Joana R.; Rapp, Hans Tore; Hentschel, Ute (Journal article; Peer reviewed, 2022)
      In the deep ocean symbioses between microbes and invertebrates are emerging as key drivers of ecosystem health and services. We present a large-scale analysis of microbial diversity in deep-sea sponges (Porifera) from ...

      The ocean plays a crucial role in the functioning of the Earth System and in the provision of vital goods and services. The United Nations (UN) declared 2021–2030 as the UN Decade of Ocean Science for Sustainable Development. ...

    • Community Composition and Habitat Characterization of a Rock Sponge Aggregation (Porifera, Corallistidae) in the Cantabrian Sea 

      Ríos, Pilar; Prado, Elena; Correia De Carvalho, Francisca; Sánchez, Francisco; Rodríguez-Basalo, Augusto; Xavier, Joana R.; Ibarrola, Teodoro P.; Cristobo, Javier (Journal article; Peer reviewed, 2020)
      Deep-sea sponge-dominated communities are complex habitats considered hotspots of biodiversity and ecosystem functioning. They are classified as Vulnerable Marine Ecosystem and are listed as threatened or declining as a ...

    • Deep-sea sponge derived environmental DNA analysis reveals demersal fish biodiversity of a remote Arctic ecosystem 

      Brodnicke, Ole Bjørn; Meyer, Heidi Kristina; Busch, Kathrin; Xavier, Joana R.; Knudsen, Steen Wilhelm; Møller, Peter Daniel Rask; Hentschel, Ute Humeida; Sweet, Michael John (Journal article; Peer reviewed, 2023)
      The deep-sea is vast, remote, and largely underexplored. However, methodological advances in environmental DNA (eDNA) surveys could aid in the exploration efforts, such as using sponges as natural eDNA filters for studying ...
