Marine invertebrates and fishes exhibit inconsistent body size responses to ocean acidification

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Body size is a fundamental characteristic of all living organisms that determines physiological functions and life‐history traits. Ecological theory predicts that ocean acidification can cause body size reductions, confirmed by several studies reporting miniaturization in ectotherms.

MAPK and GSK3/ß-TRCP-mediated degradation of the maternal Ets domain transcriptional repressor Yan/Tel controls the spatial expression of nodal in the sea urchin embryo. [PDF]

PLoS Genetics, 2018
In the sea urchin embryo, specification of the dorsal-ventral axis critically relies on the spatially restricted expression of nodal in the presumptive ventral ectoderm.

Cabomba caroliniana and Schoenoplectus californicus as Antifouling Candidates: Anti‐Attachment and Toxicological Effects in Aurelia coerulea (Cnidaria, Scyphozoa)

Environmental Toxicology, Volume 41, Issue 6, Page 356-372, June 2026.
ABSTRACT Biofouling on artificial surfaces in aquatic ecosystems leads to significant economic losses. Current antifouling paints, while effective, often harm the aquatic environment. This study explores ecologically safe antifouling alternatives derived from plants, focusing on the aquatic macrophytes Cabomba caroliniana (CC) and Schoenoplectus ...

Effects of larval diet and metamorphosis cue on survival and growth of sea urchin post-larvae (Paracentrotus lividus; Lamarck, 1816) [PDF]

, 2016
In this study, we present the results of two experiments; in the first one we evaluated the effects of four larval dietary treatments on the survival and growth of the sea urchin Paracentrotus lividus, larvae and post-larvae.

Cadmium, Copper and Tributyltin effects on fertilization of Paracentrotus lividus (Echinodermata)

Italian Journal of Animal Science, 2010
Marine environments are continuously being threatened by a large number of xenobi- otics from anthropogenic sources. The effect of chemical pollution on living organisms are numerous and may impair reproductive success of adults species of marine ...

When protection backfires: Contrasting states of macroalgal forests and sea urchin populations in a Mediterranean MPA

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
This study demonstrates that NTZs can be counterproductive, as they may exacerbate the decline of marine forests by protecting sea urchins that are not effectively controlled by predators. We therefore call for a reassessment of management policies, including the targeted harvesting of herbivores where natural top‐down control is absent.

Effects of dietary microalgae on growth, survival and fatty acid composition of sea urchin Paracentrotus lividus throughout larval development [PDF]

, 2012
This study investigated the growth, survival and fatty acid composition of sea urchin Paracentrotus lividus larvae fed four microalgal diets: Cricosphaera elongata, Pleurochrysis carterae, Tetraselmis suecica and Dunaliella tertiolecta (control).

Cost of parasite exposure depends on host ontogeny 寄生接觸的代價依賴於宿主發育階段

Ecological Entomology, Volume 51, Issue 3, Page 592-603, June 2026.
The cost of parasite exposure varies across host developmental stages, demonstrating that ontogeny influences the expression of non‐consumptive effects (NCEs). Mite exposure resulted in consumptive effects in fly eggs and NCEs in early‐stage pupae; mite longevity was comparable when provisioned with pupae or water but increased when provisioned with ...

Sea urchin holobionts: microbiome variation across species, compartments and locations in Paracentrotus lividus and Arbacia lixula

Frontiers in Marine Science
Understanding holobiont dynamics is essential for unraveling the complex interactions between marine hosts and their microbiota. Sea urchins play pivotal roles in shaping benthic ecosystems, yet the functional roles of their microbial symbionts remain ...
