Two Novel S‐methyltransferases Confer Dimethylsulfide Production in Actinomycetota

Advanced Science, Volume 13, Issue 9, 13 February 2026.
This study identifies two novel S‐adenosine‐methionine‐dependent methyltransferases, MddM1 and MddM2, in actinomycetes from the Mariana Trench. These enzymes can convert toxic hydrogen sulfide (H2S) and methanethiol (MeSH) into dimethylsulfide (DMS), serving as a cellular detoxification and oxidative stress response.

Macroid Formation in Salmacina stellaebayensis n. sp. From Mauritania's Baie de l'Étoile With New Insights on Mitogenome Evolution in Serpulidae (Annelida)

Ecology and Evolution, Volume 16, Issue 2, February 2026.
We describe Salmacina stellaebayensis n. sp. from Mauritania's Baie de l'Étoile and provide the first complete mitochondrial genome for the genus Salmacina. The species forms distinctive macroid colonies in Cymodocea nodosa seagrass meadows, offering new insights into serpulid life history and habitat specialization.

Lithistid sponges from submarine caves in the Mediterranean: taxonomy and affinities

Scientia Marina, 2011
Several lithistid sponges are described from Mediterranean caves occurring in the northwestern and Adriatic basins. In the Corallistidae, Neoschrammeniella bowerbanki and Neophrissospongia nolitangere are recorded for the first time from the ...

Invertebrate Biodiversity Associated With a Unique Bryozoan Biogenic Reef Complex (Western Port, Victoria, Australia)

Austral Ecology, Volume 51, Issue 2, February 2026.
ABSTRACT A unique biogenic bryozoan reef has been recently discovered in Western Port (a temperate embayment), Victoria, Australia. This reef is significant owing to its contiguous, regular, linear rows of densely stacked bryozoan colonies with large vertical relief. We aimed to (1) document the biodiversity of the macroinvertebrate epifauna associated

Cryptofauna Associated With the Epilithic Algal Matrix on Subtropical Brazilian Reefs

Austral Ecology, Volume 51, Issue 2, February 2026.
ABSTRACT The epilithic algal matrix (EAM) plays a significant role in the benthic cover of reefs worldwide. In Brazil, the EAM accounts for a substantial proportion of the benthos, and its associated fauna contributes to the majority of the reef's metazoan biodiversity and is an important link into the trophic chain, connecting the production performed

Mapping Mediterranean bentho‐demersal communities to better inform marine conservation

Conservation Science and Practice, Volume 8, Issue 2, February 2026.
Marine protected areas are one of the most common conservation tools being implemented worldwide to reach conservation targets, but their implementation does not usually take the heterogeneous distribution of bentho‐demersal communities into account.

Spongivory by Fishes on Southwestern Atlantic Coral Reefs: No Evidence of Top-Down Control on Sponge Assemblages

Frontiers in Marine Science, 2018
Predator-prey dynamics can affect assemblage structure and ecosystem processes representing a central theory in ecology. In coral reef ecosystems, recent evidences have suggested that sponge assemblages in regions with high diversity, like the Caribbean,

Selective Effects of Environmental Conditions and Protection Levels on Herbivorous Fish Functions in the Largest South Atlantic Reef Complex

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 1, January 2026.
ABSTRACT Herbivorous fish are key components in maintaining functionality in reef environments; however, this group is widely threatened by overfishing and habitat degradation. Investigating the main factors determining the structure of herbivorous fish becomes paramount to defining management strategies amid anthropogenic impacts. This study evaluated

Water Parameters and Hydrodynamics in Rivers and Caves Hosting Astyanax mexicanus Populations Reveal Macro‐, Meso‐ and Microhabitat Characteristics

Ecology and Evolution, Volume 16, Issue 1, January 2026.
From 2009 to 2025, we have recorded the physicochemical parameters of the water and the hydrological regimes at localities hosting Astyanax mexicanus cavefish and surface fish populations in Mexico. Sampling 13 caves and 30 surface stations revealed strong signatures of the two macrohabitats, but also significant differences in specific water ...
