The influence of biogenic habitat created by the non-indigenous bryozoan, Amathia verticillata, on the resident marine invertebrate community in San Diego, California [PDF]

Aquatic Invasions
The non-indigenous bryozoan, Amathia verticillata, has a worldwide distribution and commonly colonizes anthropogenic structures such as docks. Although widely recognized to house marine invertebrates within its structure, little is known regarding how ...

High Species Richness and Extremely Low Abundance of Cumacean Communities Along the Shelf and Slope of the Gulf of Guinea (West Africa)

Frontiers in Marine Science, 2021
The Gulf of Guinea belongs to the most scarcely sampled marine basins in the oceans of the world. We have analyzed diversity and distribution patterns of cumacean communities on the shelf and slope, along the coast of Ghana. The material was collected in

Antimicrobial Peptides from Marine Invertebrates [PDF]

Antimicrobial Agents and Chemotherapy, 2004
Marine invertebrates lack an acquired, memory-type immunity based on T-lymphocyte subsets and clonally derived immunoglobulins (72). This differs from the vertebrate immune system, which is characterized by somatic gene rearrangement, clonal selection, and expansion and a discriminative ability that includes lymphocytes, among other factors, which ...

On the Discorhabdins Leading to the Aleutianamine Ring System: A One‐Step in Situ Transformation Characterized Through Computational and Experimental Studies and Its Implications on Biosynthesis, Synthesis, and Pharmacology

Angewandte Chemie, EarlyView.
The thiocarbenium ion rearrangement of 3‐dihydrodisorhabdin B greatly increases the recovery of aleutianamine from Latrunculia spp., a pyrroloiminoquinone natural product with potent activity against drug‐resistant cancers, collected from the deep‐ocean along the Aleutian Islands.

Impact of Different Sources of Anthropogenic Pollution on the Structure and Distribution of Antarctic Marine Meiofauna Communities

Diversity
Human influence on Antarctic marine ecosystems is a growing concern, despite limited information being available. This study investigated the coastal meiofauna and environmental parameters of 10 locations, 4 of which served as reference points (OB1, OB2,
