AlkaPlorer: A database‐driven explorer for natural alkaloids and derivatives

Journal of Integrative Plant Biology, EarlyView.
The alkaloid database AlkaPlorer integrates over 130,000 compounds across 12,250 species. By linking chemical structures with biological and evolutionary data, it reveals how these molecules evolve and function. This platform serves as a vital resource for AI‐driven discovery in plant metabolism and modern drug development. ABSTRACT Alkaloids, renowned

Depth-wise variations in biofouling community development on aquaculture cage nets in the Red Sea

Egyptian Journal of Aquatic Research
This study examined the development of biofouling assemblages on cage net panels submerged at different depths in a fish farm in the Red Sea. Experimental rafts equipped with Dyneema fibre nets were submerged at depths of 5, 10 and 15  m.

Extraction, Isolation, Characterization, and Biological Activity of Sulfated Polysaccharides Present in Ascidian Viscera Microcosmus exasperatus

Pharmaceuticals, 2023
Ascidians are marine invertebrates that synthesize sulfated glycosaminoglycans (GAGs) within their viscera. Ascidian GAGs are considered analogues of mammalian GAGs and possess great potential as bioactive compounds, presenting antitumoral and ...

Ascidian Sperm Lysin System [PDF]

Zoological Science, 2002
Fertilization is a precisely controlled process involving many gamete molecules in sperm binding to and penetration through the extracellular matrix of the egg. After sperm bind to the extracellular matrix (vitelline coat), they undergo the acrosome reaction which exposes and partially releases a lytic agent called "lysin" to digest the vitelline coat ...

Propagation method and species drive survival patterns across reef zones in coral seeding on the Great Barrier Reef

Restoration Ecology, EarlyView.
Abstract Introduction Coral reef restoration increasingly relies on scalable methods, yet outcomes vary across species, propagation techniques, and habitats. Coral seeding, where coral propagules are settled on deployment units before outplanting, provides a flexible approach that accommodates both asexual (e.g. microfragments) and sexual (e.g.

Evaluating the possible role of bottom currents and internal waves in shaping seafloor morphology in a mesophotic reef

Sedimentology, EarlyView.
ABSTRACT Mesophotic reefs are located in low light conditions which, depending on the region, are usually found in water depths greater than ~30 m. They are less affected by ocean warming than reefs found in shallower water depths and thus might become increasingly important for the sustainability of marine biodiversity.

Prioritising research on endocrine disruption in the marine environment: a global perspective

Biological Reviews, Volume 101, Issue 2, Page 848-868, April 2026.
ABSTRACT A healthy ocean is a crucial life support system that regulates the global climate, is a source of oxygen and supports major economic activities. A vast and understudied biodiversity from micro‐ to macro‐organisms is integral to ocean health.

The Mediterranean Sea on the Bench: Unveiling the Marine Invertebrate Sidnyum elegans as a Source of Novel Promising Therapeutic Tools Against Triple-Negative Breast Cancer

Marine Drugs
This study aims to unveil the marine invertebrate Sidnyum elegans, a Mediterranean ascidian, as a natural resource for the early development of new treatments for triple-negative breast cancer (TNBC). Nine different fractions obtained via medium-pressure

Depth‐structured sponge assemblages offer limited evidence for mesophotic refuge potential under the deep reef refuge hypothesis

Ecography, Volume 2026, Issue 3, March 2026.
Temperate mesophotic ecosystems (TMEs) have the potential to act as climate refugia for shallower benthic species impacted by environmental change. However, the extent to which mesophotic ecosystems might provide an ecological refuge, particularly for key functional groups like sponges, remains poorly known in temperate systems.
