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. Collagen from marine sponges, known as spongin (SPG) or spongin-like collagen (SC), exhibits biocompatibility an

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.

Freshwater sponges (Spongillida: Demospongiae), including more than 240 described species, are globally distributed in continental waters (except for Antarctica), where they cover both natural and artificial surfaces. However, fragmentary studies have targeted their microbiome, making it difficult to test hypotheses about sponge-microbe specificity and metabolic relationships, along with the environmental factors playing key roles in structuring the associated microbial communities. To date, particular attention has been paid to sponges (family Lubomirskiidae) that are endemic to Lake Baikal.

Abstract:

The present study was conducted in crossbred ewes to compare the efficiency of different artificial insemination techniques with natural tupping following fixed time artificial insemination using fresh semen. Crossbred ewes (n=29) were randomly divided into three groups with 10 animals in natural tupping (NT) and laparoscopic artificial insemination (LAI) groups and nine animals in cervical artificial insemination (CAI) group. Ewes in all the treatment groups were subjected to the same estrus induction protocol: insertion of intravaginal progesterone sponges for 10 days followed by an intramus

Abstract:

Many research studies are directed toward developing safe and efficient collagen-based biomaterials as carriers for drug delivery systems. This article presents a comparative study of the properties of new collagen sponges prepared and characterized by different methods intended for biomedical applications. The structural integrity is one of the main properties for a biomaterial in order for it to be easily removed from the treated area. Thus, the effect of combining a natural polymer such as collagen with an antimicrobial drug such as oxytetracycline or doxycycline and glutaraldehyde as the c

Sponges are at the forefront of marine natural product research. In the deep sea, extreme conditions have driven secondary metabolite pathway evolution such that we might expect deep-sea sponges to yield a broad range of unique natural products. Here, we investigate the chemodiversity of a deep-sea tetractinellid sponge, Characella pachastrelloides, collected from ~800 m depth in Irish waters. First, we analyzed the MS/MS data obtained from fractions of this sponge on the GNPS public online platform to guide our exploration of its chemodiversity.

Abstract As a tropical archipelago country, Indonesia has a mega diversity of marine organisms, such as sponges. About 850 species of sponges were identified from the east part of Indonesia. The uniqueness of Indonesian marine sponges attracted many researchers to explore the sponge’s potential in producing active substances. During 1995-2016, about 40 genera of Indonesian sponges were investigated for their potential in producing pharmacological activity such as antimicrobial, anticancer, antivirus, multidrug-resistant (MDR), etc. The data showed that 56.7% of 430 reported compounds were conf

Abstract:

The waters around the western Antarctic Peninsula are experiencing fast warming due to global change, being among the most affected regions on the planet. This polar area is home to a large and rich community of benthic marine invertebrates, such as sponges, tunicates, corals, and many other animals. Among the sponges, the bright yellow Dendrilla antarctica is commonly known for using secondary diterpenoids as a defensive mechanism against local potential predators. From the dichloromethane extract of sponge samples from Deception Island collected in January 2023, we isolated a novel derivativ

Abstract Polymer sponges based on chitosan are first obtained from chitosan solutions in carbonic acid and gels based on these solutions crosslinked by a noncytotoxic agent of natural origin, genipin. A comparative analysis of the structure and mechanical strength properties of sponges prepared from chitosan solutions in carbonic and acetic acids is carried out. It is shown that the addition of genipin in an amount of ~2 wt % to a chitosan solution in carbonic acid leads to a decrease in the average pore size by ~2.5 times and a significant increase in the strength characteristics of the mater

Chronic discharge of surplus organic matter is a typical side effect of fish aquaculture, occasionally leading to coastal eutrophication and excessive phytoplankton growth. Owing to their innate filter-feeding capacity, marine sponges could mitigate environmental impact under integrated multitrophic aquaculture (IMTA) scenarios. Herein, we investigated the clearance capacity of four ubiquitous Mediterranean sponges (Agelas oroides, Axinella cannabina, Chondrosia reniformis and Sarcotragus foetidus) against three microalgal substrates with different size/motility characteristics: the nanophytop

Oceans harbor a vast biodiversity that is not represented in terrestrial habitats. Marine sponges have been the richest source of marine natural products reported to date, and sponge-derived natural products have served as inspiration for the development of several drugs in clinical use. However, many promising sponge-derived drug candidates have been stalled in clinical trials due to lack of efficacy, off-target toxicity, metabolic instability or poor pharmacokinetics. One possible solution to this high clinical failure rate is to design drug delivery systems that deliver drugs in a controlle

In contrast, striking differences of alkaloid patterns were found between sponges from shallow sites (1.8 - 11.8 m) and those collected from deeper sites (11.8 - 38.5 m). Sponges from shallow depths consistently exhibited alkaloid patterns typical for Aplysina aerophoba with aerophobin-2 (2) and isofistularin-3 (3) as main con
