Summary: Thyroid hormones have diverse physiological and developmental functions in animals and can activate both genomic and non-genomic signaling pathways. In sea urchin development, thyroid hormones regulate gene expression through both genomic and non-genomic mechanisms, with genomic signaling being more prominent during later stages of larval development.

Summary: The study found that sea urchins adapt to food-limited environments by adjusting energy allocation between reproductive capacity and modifications to their foraging apparatus. In sea urchin barrens, reproductive capacity was lower and the morphology of the foraging apparatus was more elongate.

Summary: Marine heatwave (MHW) events pose a significant threat to coastal marine ecosystems, and their impact on organisms' reproductive cycles can determine the biological consequences. The study focuses on the influence of paternal thermal history on the early development of the California purple sea urchin. It was found that exposure to elevated temperatures during early development resulted in larger, more thermally tolerant larvae, and the alignment of paternal and offspring exposure to MHW temperatures had additional positive effects on larval thermal tolerance.

Summary: Sea urchins are genetically closer to vertebrates but lack a brain. Little is known about the neurobiology of adult sea urchins. In this study, the effects of neurotransmitter receptor antagonists on the righting response of sea urchins were investigated. The results showed that glycine and adrenergic receptors are involved in tube foot movement, while dopamine receptors are involved in the neural processing of righting behavior.

Summary: The kelp forests of the California Current System have experienced prolonged marine heatwave (MHW) events that coincide with the life history events of many marine invertebrates. This study focused on the purple sea urchin and examined the effects of MHWs on gametogenesis and whether it induces transgenerational plasticity in thermal tolerance. The results showed that embryos from MHW-acclimated females had higher thermal tolerance and increased protein concentration in their eggs.

Summary: Over the last decade, there has been a rapid expansion of barren grounds caused by an overabundance of purple urchins that have destructive grazing pressure on kelp forest habitats. Harvesting purple urchins from barrens and enhancing their roe through aquaculture could potentially transform them into high-quality seafood, benefiting both the seafood industry and the restoration of kelp forests.

Summary: The sea urchin immune cell populations undergo dynamic changes in response to distinct immune stimuli and injury, particularly driven by the responses of large phagocyte populations.

Summary: The study identified the expression of repetitive elements at different stages of sea urchin embryogenesis, showing significant changes in transcription patterns during gastrulation. The expression of these elements was found to be independent of their copy number in the genome and served as population markers, with the primary mesenchyme cell lineage having the greatest diversity.

Summary: Heavy fuel oil (HFO) spills can cause long-term and significant damage to the marine environment and the reproductive functions of sea urchins, resulting in developmental toxicity effects on their offspring.

Summary: MiRNA transcriptome analysis of sea urchin larvae exposed to CO2-driven seawater acidification identified numerous novel miRNAs and predicted target genes related to growth, spicule formation, and skeletogenesis, providing insights into the impact of ocean acidification on S. purpuratus larvae.

Summary: Plastic additives used in plastic production can leach into the marine environment and cause harm to marine ecosystems. This study tested the effects of four commonly used plastic additives on the growth and survival of purple sea urchin larvae and found that they had varying degrees of impact, highlighting the need for testing the effects of plastic additives on marine organisms.

Summary: The recent collapse of predatory sunflower sea stars (Pycnopodia helianthoides) due to sea star wasting disease (SSWD) has led to the proliferation of sea urchin barrens and loss of kelp forests on the North American west coast. Experiments and a model were used to test whether restoring Pycnopodia populations could help recover kelp forests by consuming nutritionally poor purple sea urchins (Strongylocentrotus purpuratus) found in barrens. The results show that Pycnopodia has a significant impact on regulating sea urchin populations and maintaining healthy kelp forests.

Summary: The study found that larval supply of the Peruvian bay scallop in northern Chile is influenced by environmental processes, and is not clearly associated with wild benthic species. Both scallops and wild species showed significant association with lower frequency climate variability (SOI and PDO), but not the AAO. The findings suggest that larval supply patterns to Tongoy Bay may be modulated by regional patterns of climatic variability, particularly of tropical origin.

Summary: The purple sea urchin serves as a crucial research model for developmental biology, cell biology, and immunology. The study focused on protein modification and extracellular vesicles to understand their roles in health and disease, providing insights for potential biomarker development and environmental monitoring.

Summary: The SpTrf gene family from the California purple sea urchin is upregulated upon immune challenge and encodes proteins that interact with pathogens. The appearance of gene clusters may have been driven by multiple duplication and deletion events, resulting in the extant genes and family structure. The theoretical evolutionary history of these genes suggests that they have been selected for based on the survival benefits of pathogen binding and host protection in responses to pathogens.
