Photoprotective potential of gadusol against ultraviolet B radiation in melanocytes

Photochemistry and Photobiology, EarlyView.
Gadusol protects melanocytes from ultraviolet B (UVB)‐induced damage without cytotoxicity. Abstract The increasing incidence of skin cancer, including melanoma, combined with the need for ultraviolet (UV) filters that are safe for human health and marine ecosystems, is driving the search for new photoprotective agents.

Consumer diversity drives stronger predation in tropical marine communities

Ecography, Volume 2026, Issue 8, August 2026.
Biotic interactions are predicted to be stronger in the tropics compared to higher latitudes, contributing to observed patterns of global biodiversity. While increased consumer diversity and more complex food webs are expected in tropical communities, the trophic dynamics underlying strong regional effects of predation are not well understood.

Reconsidering the role of introduced species in the climate‐affected and highly invaded eastern Mediterranean

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Bioinvasions are considered mostly as a biodiversity and conservation hazard, but in specific situations, introduced species can bring ecological or socioeconomic benefits. We assessed the social–ecological role of marine introduced species in the eastern Mediterranean Sea—a global hotspot of bioinvasions and extirpations—and their potential ...

Critical Status of the Endangered Limpet Patella candei in the Canary Islands: Historical Population Trend and Environmental Stressors

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 7, July 2026.
ABSTRACT The Macaronesian endemic limpet Patella candei, also known as the ‘majorera limpet’, is an endangered species with a restricted distribution limited to Fuerteventura (Canary Islands) and the Selvagens Islands (Madeira). This study assessed its current distribution and conservation status in Fuerteventura through field surveys conducted in 2022,

Bomb Radiocarbon, Otolith Daily Increments and Length Modes Validate Age Interpretations of Chilean Jack Mackerel (Trachurus murphyi)

Frontiers in Marine Science, 2022
Ages of Chilean jack mackerel (Trachurus murphyi) in the southern Pacific Ocean were validated using three methods: 1) daily microincrement readings in sagittal otoliths of young-of-the year (YOY) fish to validate the first annulus; 2) modal progression ...

Exploring natural sunscreens: UVB protection and antioxidant properties in gadusol‐rich fish roes extracts

Photochemistry and Photobiology, Volume 102, Issue 4, Page 877-888, July/August 2026.
Gadusol‐rich extracts provide effective UVB protection and antioxidant activity in HaCaT cells and C. elegans, highlighting their potential as natural photochemoprotective agents for pharmaceutical and cosmetic applications. It also demonstrates remarkable in vitro antioxidant capacity and thermal stability over time.

Exploring Pathways to the Persistence of Community Engagement in Co‐Management Across Social‐Ecological Conditions

Conservation Letters, Volume 19, Issue 3, May/June 2026.
ABSTRACT Evaluating sustained community engagement in co‐management is critical for designing durable governance with conservation potential, yet such persistence remains rarely assessed. We analyze 750 co‐management initiatives established under Chile's Territorial Use Rights for Fishing policy (1998–2021), examining persistence across conditions ...
