Gearing Up for Warmer Times: Transcriptomic Response of Spongia officinalis to Elevated Temperatures Reveals Recruited Mechanisms and Potential for Resilience

Frontiers in Marine Science, 2020
The emblematic sponge Spongia officinalis is currently threatened by recurrent mortality incidents in its native habitats. Elevated temperature has been indicated as a major triggering factor, but the molecular mechanisms recruited for the organism’s ...

Diverse cell junctions with unique molecular composition in tissues of a sponge (Porifera)

EvoDevo, 2019
The integrity and organization of animal tissues depend upon specialized protein complexes that mediate adhesion between cells with each other (cadherin-based adherens junctions), and with the extracellular matrix (integrin-based focal adhesions ...

The coral-killing red sponge Clathria (Microciona) aceratoobtusa (Porifera: Demosponigiae) invades various coral communities of Gulf of Mannar Marine National Park, southeast India

The European Zoological Journal, 2020
Accounts of the encrusting, coral-killing sponges are increasing at an alarming rate. The present paper details about a thinly encrusting red sponge Clathria (Microciona) aceratoobtusa (Carter, 1887) which is invasive or locally spreading species and ...

Growth and feeding in the sponge Agelas tubulata from shallow to mesophotic depths on Grand Cayman Island

Ecosphere, 2021
On Caribbean coral reefs, sponges are important members of the benthic community and play multiple roles in ecosystem structure and function. They have an important role in benthic‐pelagic coupling, consuming particulate organic matter (POM) and ...

Observations on North Dakota Sponges (Haplosclerina: Spongillidae) and Sisyrids (Neuroptera: Sisyridae) [PDF]

, 2017
Factors influencing occurrence, distribution, and ecology of sponges and sisyrids are discussed, with emphasis on northeastern North Dakota. New state records for North Dakota sponges, Eunapius Jraguis Leidy and Ephydatia fluviatilis L. and the sisyrids,

Silica-associated proteins from hexactinellid sponges support an alternative evolutionary scenario for biomineralization in Porifera

Nature Communications
Metazoans use silicon traces but rarely develop extensive silica skeletons, except for the early-diverging lineage of sponges. The mechanisms underlying metazoan silicification remain incompletely understood, despite significant biotechnological and ...

Sponges as “living hotels” in Mediterranean marine caves

Scientia Marina, 2016
Although sponges constitute the dominant sessile organisms in marine caves, their functional role as ecosystem engineers has received little attention in this habitat type.

Patterns of Sponge Abundance Across a Gradient of Habitat Quality in the Wakatobi Marine National Park, Indonesia [PDF]

, 2011
Sponges are important components of reef communities worldwide, fulfilling a number of important functional roles. Habitat degradation caused by the loss of hard corals has the potential to cause increases in sponge abundance and percentage cover as they

Early animal evolution: a morphologist's view [PDF]

Royal Society Open Science, 2019
Two hypotheses for the early radiation of the metazoans are vividly discussed in recent phylogenomic studies, the ‘Porifera-first’ hypothesis, which places the poriferans as the sister group of all other metazoans, and the ‘Ctenophora-first’ hypothesis ...
