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

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 ...

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.

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

Computational 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

Multi‐proxy sequence stratigraphy of a mixed carbonate–siliciclastic shelf across the Jurassic–Cretaceous transition

The Depositional Record, Volume 12, Issue 4, September 2026.
An integrated facies, MS and XRF‐based approach applied to the Tithonian–Berriasian Sidi Khalif Formation (central Tunisia) resolves five Tithonian and eight Berriasian third‐order sequences, showing how mixed carbonate–siliciclastic shelves record coupled eustatic, climatic and tectonic controls and providing a transferable template for similar mud ...

First Report on the Diet of the Angolan Flying Squid (Todarodes angolensis) in New Zealand Waters

New Zealand Journal of Zoology, Volume 53, Issue 3, September 2026.
The Angolan flying squid (Todarodes angolensis) is a southerly distributed, large‐bodied ommastrephid preyed upon by many large marine vertebrates such as the southern elephant seal and deep‐sea squalid sharks. Here, we report its diet in New Zealand waters for the first time, identifying prey items from the stomach contents of 58 adults using ...

Integrative COI Barcoding and Species Delimitation in Echinodermata from Vietnam

Fishes
Echinoderms are marine invertebrates that play important roles in structuring marine benthic ecosystems. DNA barcoding has become a valuable tool for species identification; however, reference DNA barcode libraries for echinoderms remain incomplete. This

Ecological Reasons for the Unusually High Rate of Gastropod Drill Hole Repair in the Deep‐Sea Brachiopod Abyssothyris wyvillei From New Zealand

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 3, September 2026.
Brachiopods are able to repair drill holes made in their shells by predatory gastropods. However, in most samples examined, drill hole repair is rare to absent: Presumably the drilling attack is usually fatal to the prey. The shells of short‐looped brachiopod Abyssothyris wyvillei, from deep‐sea dredge samples from two localities in the Tasman Sea, New

Using Photographs in Fishers’ Ecological Knowledge Research: A Review and Field Study on Small‐Scale Fishers’ Knowledge of Coastal Habitats in the Central Mediterranean Sea

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT Fishers interact daily with coastal environments, which generate a deep understanding of habitat characteristics, species associations and ecological change. Fishers’ ecological knowledge (FEK) is therefore a critical source of insight for marine science, offering observations that uniquely complement scientific data and, when incorporated ...
