Spatiotemporal variability of some shallow-bottom macroinvertebrates (Gastropoda, Bivalvia and Echinodermata) from Espritu Santo Archipelago, Baja California Sur, Mexico.

Ciencias Marinas, 2006
 Four surveys (October 2001, and January, April and June 2002) were conducted at nine sites around the Espíritu Santo Archipelago, Baja California Sur, Mexico, to identify spatiotemporal variation patterns in the structure of the rocky, shallowbottom ...

Progress and Challenges in Phylogenomics and Genomics of Lophotrochozoa/Spiralia

Zoologica 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,

Larval development of Holothuria tubulosa, a new tractable system for evo-devo

Frontiers in Ecology and Evolution
To explore animal diversity, new experimentally tractable organisms must be established. Echinoderms include five groups of marine animals that have been used as developmental models for over a century thanks to their low costs, high fecundity, optically

Effects of embryo energy, egg size, and larval food supply on the development of asteroid echinoderms

Ecology and Evolution, 2020
Organisms have limited resources available to invest in reproduction, causing a trade‐off between the number and size of offspring. One consequence of this trade‐off is the evolution of disparate egg sizes and, by extension, developmental modes.

Flavouring Group Evaluation 216 Revision 3 (FGE.216Rev3): Consideration of the genotoxic potential of α,β‐unsaturated 2‐phenyl‐2‐alkenals from subgroup 3.3 of FGE.19

EFSA Journal, Volume 24, Issue 7, July 2026.
Abstract The EFSA Panel on Food Additives and Flavourings (FAF) evaluated the genotoxic potential of two flavouring substances, 2‐phenylcrotonaldehyde [FL‐no: 05.062] and 5‐methyl‐2‐phenylhex‐2‐enal [FL‐no: 05.099] from subgroup 3.3 of FGE.19, in the Flavouring Group Evaluation 216 revision 3 (FGE.216Rev3).

Sea Urchin‐Inspired Immuno‐Instructive Ionic Flow Drives MSCs‐Macrophage Communication to Promote Bone Regeneration

Advanced Materials, Volume 38, Issue 33, 12 June 2026.
ABSTRACT Bone tissue regeneration is a complex physiological process dependent on the spatiotemporal coordination of immune cells and stem cells. Conventional research primarily elucidates the mechanism through which materials facilitate bone formation by initially modulating macrophages and subsequently encouraging the osteogenic differentiation of ...

Post-larval development in deep-sea echinoderms

, 1998
The post-larval phase is an essential period in the life history of marine invertebrates; vulnerable to high mortality, it ultimately influences the distribution and abundance of adult populations.

Crinoid phylogeny: a preliminary analysis (Echinodermata: Crinoidea) [PDF]

, 2004
We describe the first molecular and morphological analysis of extant crinoid high-level inter-relationships. Nuclear and mitochondrial gene sequences and a cladistically coded matrix of 30 morphological characters are presented, and analysed by ...

Unifying Retaria Research: A Common Framework for Studying Foraminifera and Radiolaria

BioEssays, Volume 48, Issue 6, June 2026.
Research on Foraminifera and Radiolaria has predominantly focused on their fossil remains. This synthesis identifies the “Big Five” disciplines of a unified Retaria research: diversity and evolution, ecology, life cycles, and ecosystem roles, highlighting this lineage as a model system for understanding life's resilience in a rapidly changing planet ...
