Environmental Risk Assessment and Anti‐Corrosion Efficacy of Safe‐by‐Design Nitrite‐Based Nanomaterials for Maritime Applications

Nano Select, Volume 7, Issue 2, February 2026.
The environmental behavior and impact of anti‐corrosion nanoadditives, ZnAl‐NO2 and MgAl‐NO2 layered double hydroxides (LDH), are assessed under marine conditions. These nanomaterials show instability in water but exhibit no or low toxicity to most tested marine species.

Unravelling echinoid mass mortalities: a global overview of mechanisms, spatio‐temporal trends, and taxonomic insights

Biological Reviews, Volume 101, Issue 1, Page 221-236, February 2026.
ABSTRACT Mass mortality events (MMEs) have been occurring since the dawn of time. However, in contrast to terrestrial events, most marine MMEs remain undetected, largely due to the inaccessibility of many marine environments. One of the most notorious and best‐studied marine MMEs in modern times is that of the population collapse of the echinoid ...

Regulation of dynamic pigment cell states at single-cell resolution

eLife, 2020
Cells bearing pigment have diverse roles and are often under strict evolutionary selection. Here, we explore the regulation of pigmented cells in the purple sea urchin Strongylocentrotus purpuratus, an emerging model for diverse pigment function. We took

Demography and dynamics of giant kelp cohorts across four decades: Lessons for conservation and resilience planning

Ecological Applications, Volume 36, Issue 1, January 2026.
Abstract Kelp forests throughout many temperate zones are in decline due to various human stressors, chiefly marine warming. Conservation measures including restoration are presently of great interest and focus on both historical and novel methodologies.

Food limitation erodes the thermal tolerance of larvae in an ecologically influential marine herbivore

Ecology, Volume 107, Issue 1, January 2026.
Abstract Biologists often use organismal thermal tolerance to help explain or forecast responses of populations to climate change. Yet many studies quantify thermal tolerance under isolated laboratory conditions despite extreme events, such as heatwaves, often coinciding with other stressors such as nutrient or food limitation.

Developmental and Transcriptomic Responses in Sea Urchin Larvae to an Urban‐Associated Pollutant

Ecology and Evolution
Urban environments provide a unique opportunity to investigate the impacts of novel stressors on organismal performance. Marine intertidal zones exist at the transition from sea to land, where they are exposed to a unique suite of stressors, including ...

Skeletogenic Expression of Integrin Alpha, Talin and Npnt Genes and Npnt Role in Sea Urchin Skeletogenesis

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 346, Issue 1, Page 7-19, January 2026.
Three integrin alpha genes and the cytoskeletal adaptor talin are enriched in sea urchin skeletogenic cells during early skeletogenesis. The extracellular matrix protein nephronectin (Npnt) is expressed in the skeletogenic cells throughout skeletogenesis and supports normal skeletal growth, highlighting a potential role for cell–matrix interactions in ...

Examining the Role of DNA Methylation in Transcriptomic Plasticity of Early Stage Sea Urchins: Developmental and Maternal Effects in a Kelp Forest Herbivore

Frontiers in Marine Science, 2020
Gene expression plasticity can confer physiological plasticity in response to the environment. However, whether epigenetic marks contribute to the dynamics of gene expression is still not well described in most marine invertebrates. Here, we explored the

Cold Shock Compromises the Electrically Mediated Block to Polyspermy in Lytechinus variegatus Eggs

Molecular Reproduction and Development, Volume 93, Issue 1, January 2026.
ABSTRACT Exposure to low temperature prior to insemination increases the likelihood of polyspermy in Lytechinus variegatus eggs. Electrophysiological recordings reveal that cold shock partially disrupts the egg's action potential, producing a subthreshold depolarization during the fertilization response.

Excess Food Availability Can Have Detrimental Effects on Planktotrophic Larvae: Evaluation of the Quantitative Feeding on Sea Urchin Paracentrotus lividus Larval Rearing

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
Larval rearing in echinoculture still has room for optimization in order to reach economical soundness and commercial‐scale production. One of the key factors in larval feeding is to provide larvae the necessary energy for metamorphosis into juveniles. Paracentrotus lividus (Lamarck, 1816) is a meroplanktonic species with a planktotrophic larval stage,
