Demosponge diversity from North Sulawesi, with the description of six new species

open access: yesZooKeys, 2017
Sponges are key components of the benthic assemblages and play an important functional role in many ecosystems, especially in coral reefs. The Indonesian coral reefs, located within the so-called “coral triangle”, are among the richest in the world ...

3D Chitin Scaffolds of Marine Demosponge Origin for Biomimetic Mollusk Hemolymph-Associated Biomineralization Ex-Vivo

open access: yesMarine Drugs, 2020
Structure-based tissue engineering requires large-scale 3D cell/tissue manufacture technologies, to produce biologically active scaffolds. Special attention is currently paid to naturally pre-designed scaffolds found in skeletons of marine sponges, which

Habitat heterogeneity over multiple scales supports dense and diverse megafaunal communities on a northeast Pacific ridge

open access: yesLimnology and Oceanography, Volume 70, Issue 2, Page 377-392, February 2025.
ABSTRACT Marine environments are highly heterogeneous, varying across scales of a few meters to entire ocean basins. Understanding the relationship between environmental variability and species distribution is essential for area‐based management and conservation.

Contraction-Expansion and the Effects on the Aquiferous System in the Demosponge Halichondria panicea

open access: yesFrontiers in Marine Science, 2020
Contractile behavior is common among sponges despite their lack of nerves and muscles. As sessile filter-feeders, sponges rely on water with suspended food particles being pumped through their aquiferous system.

Multi‐Taxon Predictions of Deep‐Sea Corals and Sponges From Stacked Species Distribution Models in the United States West Coast Exclusive Economic Zone and Relation to Trawl Closure Zones

open access: yesDiversity and Distributions, Volume 31, Issue 2, February 2025.
ABSTRACT Aim Abundant species distribution models (SDMs) of deep‐sea corals and sponges (DSCS) allow one to make community‐level predictions about DSCS. Pairing that with the conservation information of Vulnerable Marine Ecosystems (VMEs) due to their sensitivity to seafloor trawling, one can assess the efficacy of established seafloor protections ...

The Use of Image‐Based Data and Abundance Modelling Approaches for Predicting the Location of Vulnerable Marine Ecosystems in the South Pacific Ocean

open access: yesFisheries Management and Ecology, Volume 32, Issue 1, February 2025.
ABSTRACT Vulnerable marine ecosystems (VMEs) are typically fragile and slow to recover, thereby making them susceptible to disturbance, including fishing. In the high seas, the United Nations General Assembly (UNGA) requested regional fishery management organisations (RFMOs) to implement measures to prevent significant adverse impacts on VMEs. Here, we

Determination of the Halogenated Skeleton Constituents of the Marine Demosponge Ianthella basta

open access: yesMarine 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.

The mitochondrial genome of the hexactinellid sponge : Evidence for programmed translational frameshifting [PDF]

open access: yes, 2008
Background Mitochondrial genomes (mtDNA) of numerous sponges have been sequenced as part of an ongoing effort to resolve the class-level phylogeny of the Porifera, as well as to place the various lower metazoan groups on the animal-kingdom tree.

Dynamics of Near‐Bottom Currents in Cold‐Water Coral and Sponge Areas at Valdivia Bank and Ewing Seamount, Southeast Atlantic

open access: yesJournal of Geophysical Research: Oceans, Volume 130, Issue 1, January 2025.
Abstract This study investigates near‐bottom currents and physical processes from simulations with the hydrodynamic model ROMS‐AGRIF at two seamounts of the northeast Walvis Ridge to obtain valuable insights about drivers of observed occurrences of benthic suspension feeders (cnidarians and sponges) in this data‐poor area.
