Photoperiod modulates male sexual maturation in the Emperor tetra (Nematobrycon palmeri), a strictly tropical ornamental fish

open access: yesJournal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract Photoperiod manipulation is widely used to regulate reproduction in temperate fish species, but little is known about its effects in strictly tropical species. This study evaluated whether the Emperor tetra (Nematobrycon palmeri), a tropical ornamental fish, can modulate sexual maturation in response to artificial light regimes.

Health Impact of Climate Change on Older Adults Living With Dementia: A Scoping Review

open access: yesWIREs Climate Change, Volume 17, Issue 3, May/June 2026.
Heat waves, cold events, wildfires, and hurricanes place older adults living with dementia at greater risk of hospitalization, worsened neuropsychiatric health, and mortality. ABSTRACT Relatively little is known about the association between climate change, climate variability, weather, and health among older adults living with dementia, who face ...

High‐Resolution Observations Unveil (Sub)Mesoscale Heat Fluxes Shaping Upper‐Ocean Heat Content

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Upper‐ocean heat content (UOHC) modulates air–sea exchange in tropical regions; however, its variability at (sub)mesoscale remains insufficiently resolved. Here we combine Surface Water and Ocean Topography (SWOT) observations with high‐resolution glider sections in the northeastern tropical Pacific, where mesoscale eddies and sharp frontal ...

Meridional Dipole in Eddy Activity Along Peruvian Coast During Eastern Pacific El Niño Events

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Mesoscale oceanic eddies (O $O$(100)km) play a key role in regulating climate by affecting the transport of heat and water mass properties. However, most climate models struggle to simulate these eddies due to coarse horizontal resolution. Using a 120‐year ultra‐high‐resolution simulation with 1/10° ${}^{\circ}$ horizontal ocean resolution ...

A Low‐Order Data‐Driven Model of ENSO Diversity

open access: yesGeophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Linear Inverse Models (LIMs) are widely used data‐driven tools for studying El Niño Southern Oscillation (ENSO). However, standard LIMs struggle to simulate the observed asymmetry and diversity of ENSO events. Observations reveal that strong Central Pacific (CP) La Niñas and extreme Eastern Pacific (EP) El Niños occur more frequently than ...
