The Biodiversity of Peter I Island—The Most Remote Island in the World

Ecology and Evolution, Volume 15, Issue 11, November 2025.
Peter I Island is one of the most isolated and least visited islands on earth; lying within the Antarctic Polar Front but over 420 km from continental Antarctica. Here we assess the biodiversity of the island from both previous records and our own BioBlitz in January 2022.

Seismic Disturbance, Productivity and Depth Shape Hadal Benthic Habitats and Biodiversity in the Japan, Ryukyu and Izu‐Ogasawara Trenches (Northwest Pacific Ocean)

Journal of Biogeography, Volume 52, Issue 11, November 2025.
ABSTRACT Aim This study characterises benthic habitats and associated biodiversity in three Japanese subduction trenches, and explores the effects of trench‐specific differences in large‐scale seismic events, disturbance and productivity regimes on habitat structure and assemblage composition.

Post‐Embryonic Development and Formation of the Heterocoelic Aquiferous System in Two Species of Calcareous Sponges (Calcarea, Porifera)

Molecular Reproduction and Development, Volume 92, Issue 10, October 2025.
ABSTRACT We characterized the morphogenetic processes of larval metamorphosis and the development of the olynthus and heterocoelic aquiferous system (AS) in Sycettusa hastifera (syconoid) and Paraleucilla magna (leuconoid) (Porifera, Calcarea). Metamorphosis and development up to the olynthus were similar in both species.

Microbial diversity in four Mediterranean irciniid sponges [PDF]

Biodiversity Data Journal
This paper describes a dataset of microbial communities from four different sponge species: Ircinia oros (Schmidt, 1864), Ircinia variabilis (Schmidt, 1862), Sarcotragus spinosulus Schmidt, 1862 and Sarcotragus fasciculatus (Pallas, 1766).

Sponges - systematics, as pests of molluscs, agents of bioerosion and a source of bioactive compounds [PDF]

, 2000
This paper on sponges deals mainly with 1) systematics, 2) as pests oj molluscs and agents oj bioerosion and 3) as a source of bioactive compounds. Sponges have many physical and physiological peculiarilies not seen in other animal groups, and hence ...

Applying Deep Learning to Quantify Drivers of Long‐Term Ecological Change in a Swedish Marine Protected Area

Ecology and Evolution, Volume 15, Issue 9, September 2025.
We applied an object‐detection model to archived videos from 1997‐2023 of a submarine rock wall in a Swedish marine protected area. We modeled depth distributions and abundance trends of 17 invertebrate taxa. Most taxa resided at deeper wall sections and abundance trends were generally positive, but heat sensitivity was associated with population ...

Growth Efficiency and Carbon Balance for the Sponge Haliclona oculata [PDF]

, 2009
To obtain more knowledge about carbon requirements for growth by sponges, the growth rate, respiration rate, and clearance rate was measured in situ in Haliclona oculata. We found that only 34% of the particulate carbon pumped through the sponge was used

Limited Dispersal of Benthic Environmental DNA From a Subtropical Mesophotic Shelf‐Edge Bank

Environmental DNA, Volume 7, Issue 5, September–October 2025.
We investigated the vertical and horizontal dispersion of eDNA away from an isolated mesophotic coral reef (Bright Bank) in stratified offshore waters. We found that vertical transport of benthic eDNA was limited by water column stratification and that the prevalence of eDNA from benthic invertebrates declined with horizontal distance away from the ...

Two new species in the family Axinellidae (Porifera, Demospongiae) from British Columbia and adjacent waters

ZooKeys, 2013
Two new species of Demospongiae are described for British Columbia and adjacent waters in the family Axinellidae, Auletta krautteri sp. n. and Dragmacidon kishinensis sp. n. They represent range extensions for both of these genera.

Revisiting the silicon isotopic signal of sponge skeletons and its implications

Limnology and Oceanography, Volume 70, Issue 9, Page 2480-2495, September 2025.
Abstract This study investigates the relationship between the silicon (Si) isotopic composition of sponge skeletal silica (δ30SibSi) and seawater characteristics in sponge habitats, specifically the concentration of dissolved silicic acid and its Si isotopic signature (δ30SidSi).
