Sea urchin akt activity is Runx-dependent and required for post-cleavage stage cell division

Biology Open, 2013
Summary In animal development following the initial cleavage stage of embryogenesis, the cell cycle becomes dependent on intercellular signaling and controlled by the genomically encoded ontogenetic program.

Sperm chemotaxis is driven by the slope of the chemoattractant concentration field

eLife, 2020
Spermatozoa of marine invertebrates are attracted to their conspecific female gamete by diffusive molecules, called chemoattractants, released from the egg investments in a process known as chemotaxis.

ParaHox Genes Revisited: From Gut Patterning to Integrated Axial and Neural Organization in Rotifera

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 346, Issue 4, Page 357-369, June 2026.
In rotifers, ParaHox genes show a dispersed genomic organization, with Xlox absent across gnathiferans. Exclusive neuronal expression of Gsx and Cdx reveals that ancestral ParaHox genes coordinated neural and epithelial development beyond gut patterning, suggesting an integrated role in early bilaterian body plan organization.

Comparative Neurobiology of Biogenic Amines in Animal Models in Deuterostomes

Frontiers in Ecology and Evolution, 2020
We review the occurrence of biogenic amines and their potential role as neurotransmitters in the nervous system of three groups of invertebrate deuterostomes: tunicates, cephalochordates, and echinoderms.

The complex set of internal repeats in SpTransformer protein sequences result in multiple but limited alternative alignments

Frontiers in Immunology, 2022
The SpTransformer (SpTrf) gene family encodes a set of proteins that function in the sea urchin immune system. The gene sequences have a series of internal repeats in a mosaic pattern that is characteristic of this family.

Models reveal potential synergies in management actions for bull kelp forest resilience and restoration

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
We found that urchin culling and kelp seeding interventions can be effective at rebuilding kelp forests, but require intensive effort (e.g. removing 25%–50% of urchins over multiple years), especially in the absence of predators. Our results provide recommendations for the magnitude and timing of culling and seeding that would be needed to provide ...

A novel fatty acid-binding protein-like carotenoid-binding protein from the gonad of the New Zealand sea urchin Evechinus chloroticus. [PDF]

PLoS ONE, 2014
A previously uncharacterized protein with a carotenoid-binding function has been isolated and characterized from the gonad of the New Zealand sea urchin Evechinus chloroticus. The main carotenoid bound to the protein was determined by reversed phase-high

Tissue‐Specific Plasticity of DNA Methylation Across Intertidal Microhabitats in Juvenile Mussels (Mytilus californianus)

Molecular Ecology, Volume 35, Issue 11, June 2026.
ABSTRACT Epigenetic modifications to DNA are proposed to underpin plastic responses to environmental change, and the manner in which DNA methylation contributes to plasticity likely differs among tissues. However, few studies have investigated tissue‐specific DNA methylation responses to ecologically relevant environmental stressors in natural settings.

Genomic Resources for Imperiled Caribbean Reef‐Forming Corals (Hexacorallia: Scleractinia): Complete Mitochondrial Genomes of Dichocoenia stokesii, Diploria labyrinthiformis, Oculina patagonica, and Stephanocoenia intersepta

Ecology and Evolution, Volume 16, Issue 2, February 2026.
Mitochondrial genomes of imperiled Caribbean corals are sequenced. These genomic resources will support conservation initiatives. ABSTRACT Coral reefs provide a wide variety of services essential to both marine ecosystems and human societies yet reef‐forming corals are currently facing a multitude of global and local environmental stressors.
