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

Fisheries 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

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

Frontiers 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.

The early expansion and evolutionary dynamics of POU class genes. [PDF]

, 2014
The POU genes represent a diverse class of animal-specific transcription factors that play important roles in neurogenesis, pluripotency, and cell-type specification. Although previous attempts have been made to reconstruct the evolution of the POU class,

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

Journal 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.

Evolutionary origins of sensation in metazoans: functional evidence for a new sensory organ in sponges [PDF]

, 2014
Background: One of the hallmarks of multicellular organisms is the ability of their cells to trigger responses to the environment in a coordinated manner.

Identification and Antimicrobial Potential of Marine Sponges (Carteriospongia foliascens, Callyspongia fallax, and Paratetilla arcifera) from Kenyan Marine Waters

International Journal of Microbiology, Volume 2025, Issue 1, 2025.
Emerging and re‐emerging infectious diseases and pathogens present a significant global public health threat that has led researchers to focus on discovering new antimicrobial agents in order to address the challenge. Sponges are a promising source of marine natural products, which can be used as lead molecules for drug discovery.

The Buds of Oscarella lobularis (Porifera, Homoscleromorpha): A New Convenient Model for Sponge Cell and Evolutionary Developmental Biology

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 342, Issue 8, Page 503-528, December 2024.
We describe a technique for triggering asexual reproduction by budding in vitro and have monitored bud development. The natural properties of Oscarella lobularis buds and the technical tools we developed make them a new biological system for getting insights into sponge molecular and cellular processes.

L’Argile de La Pérade : nouvelle unité marine antérieure au Wisconsinien supérieur, vallée du Saint-Laurent, Québec [PDF]

, 1990
L'Argile de La Pérade témoigne d'un nouvel épisode marin dans la vallée du Saint-Laurent, antérieur à l'Interstade de Saint-Pierre. Le nom de Mer de Cartier est formellement proposé pour désigner cette transgression marine. La nouvelle unité marine a été

rRNA depletion for holobiont metatranscriptome profiling across demosponges

, 2022
AbstractDespite the extensive knowledge of sponge microbiome diversity, a critical knowledge gap persists concerning the molecular mechanisms that govern host-symbiont interactions. Deciphering these mechanisms is crucial for understanding how sponge holobionts respond to environmental changes and identifying potential disruptions in sponge-microbe ...
