Exploring depth‐related patterns of sponge diversity and abundance in marginal reefs

Ecology and Evolution
Marine sponges play a vital role in the reef's benthic community; however, understanding how their diversity and abundance vary with depth is a major challenge, especially on marginal reefs in areas deeper than 30 m.

Hydrothermal waters enriched in silica promote the development of a sponge community in North Sulawesi (Indonesia)

The European Zoological Journal, 2017
Two shallow hydrothermal vents were investigated by SCUBA diving to evaluate their influence on the structure and diversity of a sponge community living close to the vent outflow, in the equatorial Pacific Ocean just off the coast of North Sulawesi ...

Monopodial and Sympodial Growth Modes in the Colonial Graptolithina (Hemichordata, Pterobranchia)

Evolution &Development, Volume 27, Issue 2, June 2025.
ABSTRACT Two growth modes are recognized in colonial pterobranchs (Graptolithina): monopodial growth and sympodial growth. The earliest colonial Graptolithina likely developed through monopodial growth, a mode of colony formation well‐documented in the extant graptolite Rhabdopleura normani.

Evolution of group I introns in Porifera: new evidence for intron mobility and implications for DNA barcoding

BMC Evolutionary Biology, 2017
BackgroundMitochondrial introns intermit coding regions of genes and feature characteristic secondary structures and splicing mechanisms. In metazoans, mitochondrial introns have only been detected in sponges, cnidarians, placozoans and one annelid ...

Calibrating Predicted Mixture Toxic Pressure to Observed Biodiversity Loss in Aquatic Ecosystems

Global Change Biology, Volume 31, Issue 6, June 2025.
This study bridges the gap between lab‐based chemical toxicity estimates and real‐world biodiversity loss in freshwater ecosystems. Findings show that rising toxic pressure from chemical mixtures is closely linked to declining species diversity, even at levels considered safe.

Hyperdiverse Macrofauna Communities Associated with a Common Sponge, Stylissa carteri, Shift across Ecological Gradients in the Central Red Sea

Diversity, 2019
Sponges act as important microhabitats in the marine environment and promote biodiversity by harboring a wide variety of macrofauna, but little is known about the magnitude and patterns of diversity of sponge-associated communities.

A Baseline for the Conservation of the Native and Protected Centrostephanus longispinus (Philippi, 1845) and the Management of the Invasive Diadema setosum (Leske, 1778) (Echinoidea: Diadematidae) in the Mediterranean Sea

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 5, Page 1-12, May 2025.
ABSTRACT Centrostephanus longispinus (Echinodermata: Echinoidea) is an endemic and protected sea urchin species of the Mediterranean Sea. Another long‐spined sea urchin, Diadema setosum from the Red Sea, entered the Mediterranean Sea in 2006 and rapidly spread throughout the eastern basin. As a keystone competitive grazer, D.

Assessing the regional conservation status of sponges (Porifera): the case of the Aegean ecoregion

, 2018
Sponges are among the less-studied benthic invertebrates as regards their extinction risk and conservation status. Herein, we evaluate the regional conservation status of sponges in the Aegean ecoregion (Eastern Mediterranean Sea), using the IUCN Red ...
