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 ... -
Genetic diversity, connectivity and gene flow along the distribution of the emblematic Atlanto-Mediterranean sponge Petrosia ficiformis (Haplosclerida, Demospongiae)
Riesgo, Ana; Taboada, Sergi; Pérez-Portela, Rocío; Melis, Paolo; Xavier, Joana R.; Blasco, Gema; Lopez-Legentil, Susanna (Peer reviewed; Journal article, 2019-01-16)Background: Knowledge about the distribution of the genetic variation of marine species is fundamental to address species conservation and management strategies, especially in scenarios with mass mortalities. In the ... -
Genetic diversity, gene flow and hybridization in fan-shaped sponges (Phakellia spp.) in the North-East Atlantic deep sea
Taboada, Sergi; Ríos, Pilar; Mitchell, Alex; Cranston, Alex; Busch, Kathrin; Tonzo, Vanina; Cárdenas, Paco A.; Sánchez, Francisco; Leiva, Carlos; Koutsouveli, Vasiliki; Cristobo, Javier; Xavier, Joana R.; Hentschel, Ute; Rapp v/dødsbo, Hans Tore; Morrow, Christine; Drewery, Jim; Romero, Pedro E.; Arias, Maria Belén; Whiting, Connie; Riesgo, Ana (Journal article; Peer reviewed, 2022)Deep-sea North Atlantic sponge grounds are crucial components of the marine fauna providing a key role in ecosystem functioning. To properly develop effective conservation and management plans, it is crucial to understand ... -
Long distance dispersal and oceanographic fronts shape the connectivity of the keystone sponge Phakellia ventilabrum in the deep northeast Atlantic
Taboada, Sergi; Whiting, Connie; Wang, Shuangqiang; Ríos, Pilar; Davies, Andrew J.; Mienis, Furu; Kenchington, Ellen; Cárdenas, Paco A.; Cranston, Alex; Koutsouveli, Vasiliki; Cristobo, Javier; Rapp v/dødsbo, Hans Tore; Drewery, Jim; Baldó, Francisco; Morrow, Christine; Picton, Bernard; Xavier, Joana R.; Arias, Maria Belén; Leiva, Carlos; Riesgo, Ana (Journal article; Peer reviewed, 2023)Little is known about dispersal in deep-sea ecosystems, especially for sponges, which are abundant ecosystem engineers. Understanding patterns of gene flow in deep-sea sponges is essential, especially in areas where rising ... -
The Molecular Machinery of Gametogenesis in Geodia Demosponges (Porifera): Evolutionary Origins of a Conserved Toolkit across Animals
Koutsouveli, Vasiliki; Cárdenas, Paco; Santodomingo, Nadiezhda; Marina, Anabel; Morato, Esperanza; Rapp, Hans Tore; Riesgo, Ana (Journal article; Peer reviewed, 2020)All animals are capable of undergoing gametogenesis. The ability of forming haploid cells from diploid cells through meiosis and recombination appeared early in eukaryotes, whereas further gamete differentiation is mostly ... -
Reproductive Biology of Geodia Species (Porifera, Tetractinellida) From Boreo-Arctic North-Atlantic Deep-Sea Sponge Grounds
Koutsouveli, Vasiliki; Cárdenas, Paco; Conejero, Maria; Rapp, Hans Tore; Riesgo, Ana (Journal article; Peer reviewed, 2020)Boreo-arctic sponge grounds are essential deep-sea structural habitats that provide important services for the ecosystem. These large sponge aggregations are dominated by demosponges of the genus Geodia (order Tetractinellida, ...
