Environmental Flow Regimes for Dysidea avara Sponges [PDF]

open access: yes, 2008
The aim of our research is to design tank systems to culture Dysidea avara for the production of avarol. Flow information was needed to design culture tanks suitable for effective production. Water flow regimes were characterized over a 1-year period for

Revisiting the silicon isotopic signal of sponge skeletons and its implications

open access: yesLimnology and Oceanography, Volume 70, Issue 9, Page 2480-2495, September 2025.
Abstract This study investigates the relationship between the silicon (Si) isotopic composition of sponge skeletal silica (δ30SibSi) and seawater characteristics in sponge habitats, specifically the concentration of dissolved silicic acid and its Si isotopic signature (δ30SidSi).

Metabolic responses of a phototrophic sponge to sedimentation supports transitions to sponge-dominated reefs [PDF]

open access: yes, 2017
Declines in coral abundance have been linked to increased sedimentation at many locations across the world and at some of these locations there have been subsequent increases in sponge abundance.
