Between Life and Death: Sea Urchin Embryos Undergo Peculiar DNA Fragmentation after Exposure to Vanadium, Cadmium, Gadolinium, and Selenium

Life
Exogenous DNA damage represents one of the most harmful outcomes produced by environmental, physical, or chemical agents. Here, a comparative analysis of DNA fragmentation was carried out on Paracentrotus lividus sea urchin embryos exposed to four common

2D to 3D: Exploring Variation of Niche Dimensionality Across Consumers in a Coastal Arctic Ecosystem and Implications on Interpretation

Ecology and Evolution, Volume 16, Issue 5, May 2026.
We compared the traditional two‐dimensional (2D: δ13C and δ15N) isotopic niches with a three‐dimensional (3D: δ13C, δ15N, and δ34S) framework to evaluate changes in niche size and overlap. Overall, invertebrates and benthic‐associated species showed greater changes in niche size and reduced overlap using the 3D approach.

Functional Morphology of the Oral Jaws and Dentition Across Diverse Diets and Ontogeny in Prickleback Fishes (Stichaeidae)

Journal of Morphology, Volume 287, Issue 5, May 2026.
Prickleback fishes (Stichaeidae) feed upon diverse diets, spanning carnivory (orange), omnivory (blue), and herbivory (green). We used microCT scanning to explore the functional morphology of the oral jaws and dentition across species and ontogeny. Focal species vary by morphotype and have divergent scaling patterns across diets.

Panama Canal expansion and shifts in fishing practices: A social‐ecological network approach

People and Nature, Volume 8, Issue 5, Page 1520-1532, May 2026.
Abstract Species introductions have spiked over the past two centuries due to globalization. These introductions impact ecosystems, but may also have long‐term implications for human communities. In one of the world's hubs for global shipping, the Panama Canal, a recent canal expansion has coincided with an increase in marine fishes entering the ...

Control Strategies in Guanine Biocrystallization

Angewandte Chemie, Volume 138, Issue 18, 27 April 2026.
Biological guanine crystals produce spectacular photonic phenomena in animals and hold great promise as new, sustainable optical materials. We review how organisms precisely control the structure, morphologies, and resulting optical properties of these crystals using a set of ingenious ‘design’ strategies, including control of pH, template‐directed ...

Ecotoxicological Evaluation of Organic Sunscreens Used Worldwide, Alone and in Mixture, on Terrestrial Plants

Environmental Toxicology, Volume 41, Issue 5, Page 257-269, May 2026.
ABSTRACT The environmental hazards of sunscreens are discussed worldwide. However, there are few ecotoxicological studies on these compounds alone for edaphic organisms, and none for their mixtures. Avobenzone (1 and 10 ng/L), octocrylene (10 and 100 μg/L), and oxybenzone (2 and 20 μg/L), alone and in binary combinations (between the lowest and the ...

Great Meteor Seamount Circulation Revisited: Insights Into Cold‐Water Coral Habitat Potential

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract Seamounts play a crucial role in shaping deep‐sea ecosystem structure, influencing ocean circulation, enhancing biological productivity, and supporting diverse marine life. The Great Meteor Seamount (GMS), is the largest seamount in the North Atlantic and a key ecological feature in the regional network of the Protected Areas of the Azores ...

Remote Text‐Supplemented Audiobook Intervention Supports Children's Explicit and Incidental Vocabulary Learning

Developmental Science, Volume 29, Issue 3, May 2026.
ABSTRACT Vocabulary knowledge is foundational to educational success, but significant gaps exist between students with reading disabilities or those from disadvantaged backgrounds and their peers. These gaps have cascading effects, as children with lower vocabulary knowledge are less likely to acquire new words through independent reading and are less ...
