Abstract:
Marine sponge holobionts, defined as filter-feeding sponge hosts together with their associated microbiomes, are prolific sources of natural products. The inventory of natural products that have been isolated from marine sponges is extensive. Here, using untargeted mass spectrometry, we demonstrate that sponges harbor a far greater diversity of low-abundance natural products that have evaded discovery. While these low-abundance natural products may not be feasible to isolate, insights into their chemical structures can be gleaned by careful curation of mass fragmentation spectra. Sponges are a

Abstract:
Some animals have basic culture, but to date there is not much evidence that cultural traits evolve as part of a cumulative process as seen in humans. This may be due to limits in animal physical cognition, such as an inability to compare the efficiency of a novel behavioural innovation with an already existing tradition. We investigated this possibility with a study on a natural tool innovation in wild chimpanzees: moss-sponging, which recently emerged in some individuals to extract mineral-rich liquids at a natural clay-pit. The behaviour probably arose as a variant of leaf-sponging, a tool

Abstract:
The use of collagen-based biomaterials in tissue engineering has surged in recent decades due to collagen's advantages, including biocompatibility, controlled biodegradation, and support for cell adhesion and differentiation. Traditional collagen sources, often from bovine or porcine origins, pose challenges such as zoonotic risks, immunogenic reactions, and ethical concerns. To address these limitations, researchers are exploring innovative collagen sources, such as marine sponges.

Abstract:
Marine sponges have emerged as effective natural samplers of environmental DNA (eDNA), offering a promising alternative for biodiversity monitoring. By filtering large volumes of seawater, sponges accumulate eDNA from surrounding communities, potentially enhancing species detection in marine environments where conventional water sampling is limited. In this study, we evaluated the eDNA recovery efficiency of seven Mediterranean sponge species to identify optimal candidates for biomonitoring.

Abstract The chemical ecology and chemical defenses of sponges have been investigated for decades; consequently, sponges are among the best understood marine organisms in terms of their chemical ecology, from the level of molecules to ecosystems. Thousands of natural products have been isolated and characterized from sponges, and although relatively few of these compounds have been studied for their ecological functions, some are known to serve as chemical defenses against predators, microorganisms, fouling organisms, and other competitors.

Marine sponges and corals are widely recognized as rich sources of novel bioactive natural products. These organisms are frequently colonized by bacteria. Some of these bacteria can be pathogenic or serve as beneficial symbionts. Therefore, these organisms need to regulate the bacteria they encounter and resist microbial pathogens. One method is by chemical defense.
