Unravelling Hidden Trophic Interactions Among Sea Urchin Juveniles and Macroinvertebrates by DNA Amplification [PDF]

Molecular Ecology, Volume 34, Issue 24, December 2025.
ABSTRACT Rocky reefs may shift between two distinct stable states: productive algal forests, characterised by high abundance and biodiversity of macrofauna, and impoverished barrens, dominated by overgrazing sea urchins. Barren states may persist despite the recovery of adult sea urchin predators, suggesting additional stabilising mechanisms.

Transcriptomic analysis reveals insights into deep-sea adaptations of the dominant species, Shinkaia crosnieri (Crustacea: Decapoda: Anomura), inhabiting both hydrothermal vents and cold seeps [PDF]

BMC Genomics, 2019
Background Hydrothermal vents and cold seeps are typical deep-sea chemosynthetically-driven ecosystems that allow high abundance of specialized macro-benthos.

Effects of Climate‐Responsive, Fjordscape, and Aquaculture‐Associated Environmental Drivers on Fjord Hyperbenthic Community Structure

Journal of Geophysical Research: Oceans, Volume 130, Issue 4, April 2025.
Abstract Marine community sensitivity to climate change can be informed by examining community patterns along current environmental gradients. Fjords provide natural laboratories for such studies due to their variable oceanographic conditions that can differ from basin to basin.

Positive species interactions structure rhodolith bed communities at a global scale

Biological Reviews, Volume 100, Issue 1, Page 428-444, February 2025.
ABSTRACT Rhodolith beds are diverse and globally distributed habitats. Nonetheless, the role of rhodoliths in structuring the associated species community through a hierarchy of positive interactions is yet to be recognised. In this review, we provide evidence that rhodoliths can function as foundation species of multi‐level facilitation cascades and ...
