Divergence times in demosponges (Porifera): first insights from new mitogenomes and the inclusion of fossils in a birth-death clock model

, 2017
Approximately 80% of all recent sponge species belong to the class Demospongiae. Yet, despite their diversity and importance, accurate divergence times are still unknown for most demosponge clades.

Convergent antifouling activities of structurally distinct bioactive compounds synthesized within two sympatric Haliclona Demosponges

, 2009
A wide range of sessile and sedentary marine invertebrates synthesize secondary metabolites that have potential as industrial antifoulants. These antifoulants tend to differ in structure, even between closely related species.

In Murky waters : Swedish demosponges and their genealogies

, 2022
Swedish Sponge fauna last updated happened over 80’s years ago. This fact explains, partially, the country’s low sponge. In this thesis, I update our knowledge of the swedish demosponge fauna (Paper I and II) and, give an insight to the relationship within one of the most common sponge groups in the country belonging to order Suberitida (Paper III and ...

Drivers Of Rhythmic Contractions In The Temperate Demosponges Tethya Californiana And Hymeniacidon Perlevis

Sponges (Phylum Porifera) are suspension feeders whose water filtration is important to benthic ecosystems because of their conversion of large amounts of dissolved carbon and nitrogen into particulate waste available for detritivores.
