eDNA Collected by Custom‐Built Unmanned Surface Vehicles (USVs) Reveals Spatio‐Temporal Shifts in Tropical Coral Reef Faunal Communities

open access: yesEnvironmental DNA, Volume 8, Issue 4, July‐August 2026.
Self‐constructed Unmanned Surface Vehicles were deployed at coral reefs on Reunion Island to capture environmental DNA (eDNA), identifying changes in animal communities depending on the time of day and sampling station. These findings suggest specific sites for high‐frequency, long‐term eDNA monitoring using low‐cost mobile devices.

Mollusca, Nudibranchia: new records and southward range extensions in Santa Catarina, southern Brazil [PDF]

open access: yesCheck List, 2011
Nudibranch molluscs constitute a group of marine gastropods little studied in most of the Brazilian coast extension. Up to date, only ten species are known from Santa Catarina state, southern Brazil.

Predatory behaviour on Ostracoda: spatial analysis of drill‐hole distribution in relation to shell size and ornamentation

open access: yesPalaeontology, Volume 69, Issue 4, July/August 2026.
Abstract Palaeobiological evidence of predation on ostracods derives primarily from drill‐hole traces. However, this record is limited to sparse reports and rare quantitative analyses hinder understanding of influence of predator–prey interaction in the evolution of ostracods. Moreover, predation is rarely studied in deep‐water settings.

Allelochemistry of some Hawaiian dorid nudibranchs [PDF]

open access: yes, 1981
Several novel metabolites were isolated from Hawaiian dorid nudibranchs, an order of brightly colored marine mollusks. The metabolites are believed to serve as defense allomones.

Gene Expression and Structural Differences Underpinning Black and White Colouration in Spiders

open access: yesMolecular Ecology, Volume 35, Issue 12, June 2026.
ABSTRACT The presence of multiple color variants within a single population, known as color polymorphism, is a striking example of intraspecific phenotypic variation and a model for studying evolutionary processes. These processes depend on the underlying mechanisms such as the genes and pigments involved; but we currently lack such information for non‐

DNA Metabarcoding Reveals Unexpected Predator–Prey–Microbial Dynamics in the Southern Right Whale (Eubalaena australis)

open access: yesMolecular Ecology, Volume 35, Issue 12, June 2026.
ABSTRACT Southern right whale (Eubalaena australis; SRW) populations are recovering from the impacts of commercial whaling, however, recovery has been spatially variable, with strong associations between reproduction and prey availability. The diet of SRWs has not been widely examined, and with SRW foraging shifting away from high‐latitude foraging ...

The complete mitochondrial genome of the photosymbiotic sea slug Berghia stephanieae (Valdés, 2005) (Gastropoda, Nudibranchia)

open access: yesMitochondrial DNA. Part B. Resources, 2021
Berghia stephanieae (Nudibranchia, Cladobranchia) is a photosymbiotic sea slug that feeds exclusively on sea anemones from the genus Exaiptasia. It then specifically incorporates dinoflagellates belonging to the Symbiodiniaceae obtained from their prey ...

2D to 3D: Exploring Variation of Niche Dimensionality Across Consumers in a Coastal Arctic Ecosystem and Implications on Interpretation

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
We compared the traditional two‐dimensional (2D: δ13C and δ15N) isotopic niches with a three‐dimensional (3D: δ13C, δ15N, and δ34S) framework to evaluate changes in niche size and overlap. Overall, invertebrates and benthic‐associated species showed greater changes in niche size and reduced overlap using the 3D approach.
