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 ... -
Molecular Phylogeny of the Astrophorida (Porifera, Demospongiaep) Reveals an Unexpected High Level of Spicule Homoplasy
Cárdenas, Paco; Xavier, Joana R.; Reveillaud, Julie; Schander, Christoffer; Rapp, Hans Tore (Peer reviewed; Journal article, 2011-04-08)Background: The Astrophorida (Porifera, Demospongiaep) is geographically and bathymetrically widely distributed. Systema Porifera currently includes five families in this order: Ancorinidae, Calthropellidae, Geodiidae, ... -
Phylogeny, Taxonomy and Evolution of the Astrophorida (Porifera, Demospongiae)
Cárdenas, Paco (Doctoral thesis, 2010-06-04)The Astrophorida (Porifera, Demospongiae) currently represent ca 660 extant species worldwide. In tropical and parts of warm temperate waters they are common at quite shallow depths, while in boreal/antiboreal and Arctic ... -
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, ... -
Rock sponges (lithistid Demospongiae) of the Northeast Atlantic seamounts, with description of ten new species
Correia De Carvalho, Francisca; Cárdenas, Paco; Ríos, Pilar; Cristobo, Javier; Rapp, Hans Tore; Xavier, Joana R. (Journal article; Peer reviewed, 2020)Background Lithistid demosponges, also known as rock sponges, are a polyphyletic group of sponges which are widely distributed. In the Northeast Atlantic (NEA), 17 species are known and the current knowledge on their ...
