Genomic analysis of NE Atlantic sardine (Sardina pilchardus) reveals reduced variation in a recently established North Sea population and directs reconsideration of management units

open access: yesEcology and Evolution
The European sardine (Sardina pilchardus) is under intense fishing pressure and exhibits distributional/abundance shifts linked to environmental change.

Dynamic Fluorescence Modulation via Light‐Driven Competitive Protonation

open access: yesAdvanced Optical Materials, EarlyView.
A two‐component molecular system demonstrates reversible, light‐driven fluorescence write–erase cycling and thermal imaging. Illumination of a merocyanine photoacid transfers a proton to a highly efficient fluorescent pyridinium dye, switching its emission color; thermal relaxation reverses the process in the dark.

Plankton vertical migrations - Implications for the pelagic ecosystem [PDF]

open access: yes, 2011
Habitat selection is an important behavior of many organisms. The direction and strength of this behavior is often characterized as a result of a trade off between predator avoidance and obtaining resources. A characteristic example of this trade off may

Metazoan Diversity and Its Drivers: An eDNA Survey in the Pacific Gateway of a Changing Arctic Ocean

open access: yesEnvironmental DNA
Climate change drives species to adapt or undergo range shifts to survive. The Arctic Ocean, experiencing more drastic environmental changes than any other ocean, has two primary inflow regions that facilitate these shifts: the wide, deep Atlantic ...

Coherent Absorption Reveals Colors Hidden in a Grey Fabry–Pérot Cavity

open access: yesAdvanced Optical Materials, EarlyView.
A dielectric thin film shows colors depending on its thickness; this effect can be used to encode information normally accessible through single‐beam spectroscopy. We developed a method to conceal this kind of information, based on coating the dielectric with a matched conductor, that suppresses the color‐bearing thin‐film resonances.

From Lab to Landscape: Environmental Biohybrid Robotics for Ecological Futures

open access: yesAdvanced Robotics Research, EarlyView.
This Perspective explores environmental biohybrid robotics, integrating living tissues, microorganisms, and insects for operation in real‐world ecosystems. It traces the leap from laboratory experiments to forests, wetlands, and urban environments and discusses key challenges, development pathways, and opportunities for ecological monitoring and ...

The known and unknown about Marine Biodiversity in Ecuador (Continental and Insular) Lo conocido y desconocido de la Biodiversidad Marina en el Ecuador (Continental e Insular)

open access: yesGayana, 2003
Ecuador has a high diversity of ecosystems in its coastal and marine territory with beaches, bays, estuaries, cliffs, coastal lagoons and rocky coasts being the most representative. So far, 1,859 marine species have been identified in Ecuador.

A Pentaradial and Bilateral Combined Photoreception System in the Sea Cucumber is Mediated by a Blue Light‐Sensitive R‐Opsin

open access: yesAdvanced Science, EarlyView.
The sea cucumber Holothuria leucospilota detects blue and adjacent wavelengths of light via an r‐opsin with a maximum absorption at 459 nm. In the oral tentacles, papillae, and tube feet, distinct light‐sensing structures with specialized morphologies are formed, constituting a unique pentaradial and bilateral combined photoreception system.
