Effect of Acute Thermal Stress Exposure on Ecophysiological Traits of the Mediterranean Sponge Chondrilla nucula: Implications for Climate Change

open access: yesBiology, 2023
As a result of climate change, the Mediterranean Sea has been exposed to an increase in the frequency and intensity of marine heat waves in the last decades, some of which caused mass mortality events of benthic invertebrates, including sponges.

Fan worms (Annelida: Sabellidae) from Indonesia collected by the Snellius II Expedition (1984) with descriptions of three new species and tube microstructure [PDF]

open access: yesPeerJ, 2020
The Indonesian archipelago is one of the most diverse regions in the marine World. Many contributions on polychaete worms have been published since the Dutch Siboga Expedition to the Indonesian archipelago at the end of the 19th century.

Information-theoretic signatures of biodiversity in the barcoding gene

open access: yes, 2018
The COI mitochondrial gene is present in all animal phyla and in a few others, and is the leading candidate for species identification through DNA barcoding.

The evolution of reproduction in Ediacaran–Cambrian metazoans

open access: yesBiological Reviews, EarlyView.
ABSTRACT The evolution of reproductive style is a fundamental aspect of metazoan life history but has not been explored holistically through the Ediacaran–Cambrian rise of metazoans. Recent molecular clock analyses based on only unequivocal metazoan fossil calibrations suggest that Porifera were present by at least 590 million years ago (Ma), all major

Sponges as “living hotels” in Mediterranean marine caves

open access: yesScientia 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.

Comparative Chemical Profiling and Antimicrobial/Anticancer Evaluation of Extracts from Farmed versus Wild Agelas oroides and Sarcotragus foetidus Sponges

open access: yesMarine Drugs, 2023
Marine sponges are highly efficient in removing organic pollutants and their cultivation, adjacent to fish farms, is increasingly considered as a strategy for improving seawater quality.

Recovery at Morvin: SERPENT final report [PDF]

open access: yes, 2010
Recovery from disturbance is poorly understood in deep water, but the extent of anthropogenic impacts is becoming increasingly well documented. We used Remotely Operated Vehicles (ROV) to visually assess the change in benthic habitat after exploratory ...

Benthic foraminifers and siliceous sponge spicules assemblages in the Quaternary rhodolith rich sediments from Pontine Archipelago shelf [PDF]

open access: yes, 2016
The bottom samples (Quaternary in age) of two cores (CS1 and Caro1) collected at 60 and 122 m water depth in the marine area near Ponza Island (Pontine Archipelago, Tyrrhenian Sea) are investigated.

Divergence times in demosponges (Porifera): first insights from new mitogenomes and the inclusion of fossils in a birth-death clock model

open access: yesbioRxiv, 2017
BackgroundApproximately 80% of all described extant sponge species belong to the class Demospongiae. Yet, despite their diversity and importance, accurate divergence times are still unknown for most demosponge clades.

Evolution of Haplosyllis (Syllidae, Annelida) With Emphasis on the Indo‐Pacific Region and the djiboutiensis Species Complex

open access: yesZoologica Scripta, EarlyView.
ABSTRACT Haplosyllis is a worldwide distributed genus of marine annelids, commonly associated with other invertebrates. Its characteristic simple bidentate chaetae have often led to mistakes in estimating the real diversity of the genus. Currently, Haplosyllis includes 38 species, nearly half of which inhabit the Indo‐West Pacific (IPW).
