Marine Ecology, Volume 43, Issue 2, April 2022., 2022 Abstract Anthropogenic disturbances affect the health of coral reefs worldwide and may also impact hawksbill (Eretmochelys imbricata) foraging areas, potentially decreasing sponge numbers, while increasing macroalgae. Few studies have been conducted to understand energy content of hawksbill prey.

Biomimetic Graphene/Spongin Scaffolds for Improved Osteoblasts Bioactivity via Dynamic Mechanical Stimulation [PDF]
Macromolecular Bioscience, 2021 AbstractBiomimetics offers excellent prospects for design a novel generation of improved biomaterials. Here the controlled integration of graphene oxide (GO) derivatives with a 3D marine spongin (MS) network is explored to nanoengineer novel smart bio‐based constructs for bone tissue engineering.

Lethaia, Volume 54, Issue 5, Page 823-844, December 2021., 2021 The so‐called Permian–Triassic mass extinction was followed by a prolonged period of ecological recovery that lasted until the Middle Triassic. Triassic stromatolites from the Germanic Basin seem to be an important part of the puzzle but have barely been investigated so far.

The ‘classic stromatolite’ Cryptozoön is a keratose sponge‐microbial consortium
Geobiology, Volume 19, Issue 2, Page 189-198, March 2021., 2021 Abstract Animal evolution transformed microbial mat development. Canonically inferred negative effects include grazing, disturbance and competition for space. In contrast, ancient examples of cooperation between microbial mats and invertebrates have rarely been reported.

Bioglass-Reinforced Spongin-Like Collagen Scaffolds for Osteoporotic Bone Tissue Engineering
ACS OmegaOsteoporotic fractures pose a significant clinical challenge due to impaired bone regeneration. In this study, composite scaffolds based on Bioglass 45S5 (BG) and marine-derived spongin-like collagen (SPG) were developed and analyzed. Characterization techniques included scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy ...

Determination of the Halogenated Skeleton Constituents of the Marine Demosponge Ianthella basta
Marine Drugs, 2017 Demosponges of the order Verongida such as Ianthella basta exhibit skeletons containing spongin, a collagenous protein, and chitin. Moreover, Verongida sponges are well known to produce bioactive brominated tyrosine derivatives.

Adsorption of C.I. Natural Red 4 onto Spongin Skeleton of Marine Demosponge [PDF]
Materials, 2014 C.I. Natural Red 4 dye, also known as carmine or cochineal, was adsorbed onto the surface of spongin-based fibrous skeleton of Hippospongia communis marine demosponge for the first time. The influence of the initial concentration of dye, the contact time, and the pH of the solution on the adsorption process was investigated.
