Effects of seawater acidification on cell cycle control mechanisms in Strongylocentrotus purpuratus embryos. [PDF]

open access: yesPLoS ONE, 2012
Previous studies have shown fertilization and development of marine species can be significantly inhibited when the pH of sea water is artificially lowered.

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

Evaluating Spatial Compliance of Protected Areas by Recreational Fishers and Resulting Ecological Responses of Temperate Rocky Reefs

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.
ABSTRACT Protected areas (PA) are widely used to mitigate overfishing, but their conservation value depends on their size, age, take/no‐take regulations, compliance and enforcement. We evaluated fisher compliance of PAs within Barkley Sound, Canada, using recreational fishing effort location data from aerial surveys (2021–2023).

Antimicrobial peptides in Echinoderms [PDF]

open access: yesInvertebrate Survival Journal, 2010
Antimicrobial peptides (AMPs) are important immune effector molecules for invertebrates, including echinoderms, which lack a vertebrate-type adaptive immune system. Here we summarize the knowledge of such peptides in echinoderms.

Conditioning cultured Diadema antillarum through uncaged mid‐water grow‐out shifts behavior and morphology

open access: yesRestoration Ecology, Volume 34, Issue 5, July 2026.
Abstract Introduction The long‐spined black sea urchin Diadema antillarum is a keystone herbivore on Caribbean reefs, yet population recovery following mass mortality events has been slow and spatially variable. Restocking programs increasingly rely on aquaculture, but rearing conditions may generate behavioral and morphological shifts that affect post‐

Elements of divergence in germline determination in closely related species

open access: yesiScience, 2023
Summary: Evolutionary transitions are particularly important in development of the germ line, cells which directly impact sexual reproduction. Differences in the primordial germ cells (PGCs) of two sea urchin species were examined here by stage-matched ...

Progress and Challenges in Phylogenomics and Genomics of Lophotrochozoa/Spiralia

open access: yesZoologica Scripta, Volume 55, Issue 4, Page 521-544, July 2026.
ABSTRACT Lophotrochozoa is one of the three major bilaterian groups comprising more than half of the bilaterian phyla. Lophotrochozoa includes among others Mollusca, Annelida, Platyhelminthes and Rotifera. Despite representing such a large proportion of animal diversity, they are historically understudied and genomic resources have been scarce. However,

When species don't move together: Non-concurrent range shifts in Eastern Pacific kelp forest communities.

open access: yesPLoS ONE
Species range shifts due to changing ocean conditions are occurring around the world. As species move, they build new interaction networks as they shift from or into new ecological communities.

The impact of gene expression variation on the robustness and evolvability of a developmental gene regulatory network. [PDF]

open access: yesPLoS Biology, 2013
Regulatory interactions buffer development against genetic and environmental perturbations, but adaptation requires phenotypes to change. We investigated the relationship between robustness and evolvability within the gene regulatory network underlying ...

Possible role of microtubules in vesicular transport of matrix protein during sea urchin larval biomineralization

open access: yesDevelopmental Dynamics, Volume 255, Issue 6, Page 585-601, June 2026.
Abstract Background Biomineralization is a vital biological process through which organisms produce mineralized structures such as shells, skeletons, and teeth. Microtubules are essential for biomineralization in various eukaryotic species; however, their specific roles in this process remain unclear.
