First record of the starfish Luidia atlantidea in the Canary Islands [PDF]

open access: yes, 2018
We document the first observations of Luidia atlantidea Madsen, 1950 (Luidiidae; Paxillosida, Asteroidea) along the coasts of the Canary Islands, which represents a new westward occurrence of its known range.

Radial Glia in Echinoderms [PDF]

open access: yesDevelopmental Neurobiology, 2018
AbstractRadial glial cells are crucial in vertebrate neural development and regeneration. It has been recently proposed that this neurogenic cell type might be older than the chordate lineage itself and might have been present in the last common deuterostome ancestor.

Identification of Crucial Drug Targets and Pathways to Reprogram Drug Resistance Through Epigenetic Modulation in Advanced Lung Cancer Using Integrated Bioinformatics Approach

open access: yesComputational and Systems Oncology, Volume 6, Issue 1, December 2026.
ABSTRACT Resistance to chemotherapy, which is demonstrated in almost every patient with advanced‐stage lung cancer (ALC), underscores an urgent need to unravel the underlying molecular mechanisms and identify novel strategies to overcome drug resistance. In the present study, an attempt was made to identify epigenetic targets and modulators that can be

Sea Urchins as an Inspiration for Robotic Designs

open access: yesJournal of Marine Science and Engineering, 2018
Neuromorphic engineering is the approach to intelligent machine design inspired by nature. Here, we outline possible robotic design principles derived from the neural and motor systems of sea urchins (Echinoida).

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

open access: yesJournal 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.

Herbivore regulation of plant abundance in aquatic ecosystems. [PDF]

open access: yes, 2017
Herbivory is a fundamental process that controls primary producer abundance and regulates energy and nutrient flows to higher trophic levels. Despite the recent proliferation of small-scale studies on herbivore effects on aquatic plants, there remains ...

Internalized Evolutionary Inertia on Body Plan Evolution

open access: yesEvolution &Development, Volume 28, Issue 2, June 2026.
Animal development appears to intrinsically bias phenotypic evolution, though the exact mechanism is unclear. This review discusses potential mechanisms by which animal embryogenesis limits phenotypic diversification and considers whether inherent evolutionary inertia could allow us to predict future evolutionary paths.

Environmental controls on the distribution of neoselachian sharks and rays within the British Bathonian (Middle Jurassic). [PDF]

open access: yes, 2003
Extensive sampling from a range of facies within the Bathonian (Middle Jurassic) of southern England has allowed the palaeoenvironmental distribution of a number of taxa of neoselachian sharks and rays to be assessed.
