Seasonality shapes gut microbiota composition in two sympatric sea urchins [PDF]

PeerJ
Background The gut microbiota plays critical roles in digestion, immunity, and environmental adaptation in marine invertebrates. Its composition is shaped by both host traits and abiotic factors such as temperature and seasonality.

A scuticociliate causes mass mortality of Diadema antillarum in the Caribbean Sea. [PDF]

Sci Adv, 2023
Echinoderm mass mortality events shape marine ecosystems by altering the dynamics among major benthic groups. The sea urchin Diadema antillarum , virtually extirpated in the Caribbean in the early 1980s by an unknown cause, recently experienced another mass mortality beginning in January 2022.

El primer genoma mitocondrial completo de Diadema antillarum (Diadematoida, Diadematidae) [PDF]

, 2022
The mitochondrial genome of the long-spined black sea urchin, Diadema antillarum, was sequenced using Illumina next-generation sequencing technology. The complete mitogenome is 15,708 bp in length, containing two rRNA, 22 tRNA and 13 protein-coding ...

Can sea urchins beat the heat? Sea urchins, thermal tolerance and climate change [PDF]

PeerJ, 2015
The massive die-off of the long-spined sea urchin, Diadema antillarum, a significant reef grazer, in the mid 1980s was followed by phase shifts from coral dominated to macroalgae dominated reefs in the Caribbean.

Applying coral breeding to reef restoration: best practices, knowledge gaps, and priority actions in a rapidly‐evolving field

Restoration Ecology, Volume 31, Issue 7, September 2023., 2023
Reversing coral reef decline requires reducing environmental threats while actively restoring reef ecological structure and function. A promising restoration approach uses coral breeding to boost natural recruitment and repopulate reefs with genetically diverse coral communities. Recent advances in predicting spawning, capturing spawn, culturing larvae,

Sargassum polyceratium (Phaeophyceae, Fucaceae) surface molecule activity towards fouling organisms and embryonic development of benthic species [PDF]

, 2011
International audienceCoral reefs have undergone profound ecological changes over recent decades. Areas formerly covered by scleractinian coral species are now often overgrown by macroalgae.

Co‐occurrence of herbivorous fish functional groups correlates with enhanced coral reef benthic state

Global Ecology and Biogeography, Volume 32, Issue 3, Page 435-449, March 2023., 2023
Abstract Aim Biodiversity loss is impacting essential ecosystem functions and services across the globe. Recently, our interest in the benefits of biodiversity for ecosystem function has shifted focus from measurements of species richness to functional diversity and composition.

Contrasting influence of seascape, space and marine reserves on genomic variation in multiple species

Ecography, Volume 2023, Issue 1, January 2023., 2023
Marine reserves are being established worldwide to conserve and manage marine resources, and are also often assumed to conserve the evolutionary potential of marine populations. However, comparisons of genomic patterns inside and outside marine reserves in multiple species are scarce.
