Shifting Seas, Changing Diets: Evidence of Temporal Dietary Shifts in Marine Megafauna in Southern Brazil (2017–2023)

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 5, May 2026.
ABSTRACT Understanding the dietary dynamics of marine megafauna is essential for interpreting ecological interactions and assessing environmental changes in marine ecosystems. We analysed temporal trends in the diets of eight megafaunal species, comprising marine mammals, seabirds, and sea turtles.

Trends in marine species distribution models: a review of methodological advances and future challenges

open access: yesEcography, Volume 2026, Issue 5, May 2026.
Correlative species distribution models (SDMs) are quantitative tools in biogeography and macroecology. Building upon the ecological niche concept, they correlate environmental covariates to species presence to model habitat suitability and predict species distributions.

Bycatch of marine mammals and seabirds: Occurrence and mitigation

open access: yes, 2021
Gillnet fisheries are generally considered environment-friendly, causing limited bottom-impact and generating high-quality fish. Nevertheless, gillnets are also associated with high risks of bycatch of non-target animals, including seabirds and marine mammals. To fulfil Denmark’s obligations with regards to European legislations and other international

Assessing the Effects of Banana Pingers as a Bycatch Mitigation Device for Harbour Porpoises (Phocoena phocoena)

open access: yesFrontiers in Marine Science, 2020
Bycatch is a significant cause of population declines of marine megafauna globally. While numerous bycatch mitigation strategies exist, acoustic alarms, or pingers, are the most widely adopted strategy for small cetaceans.

Resilience to Cardiac Aging in Greenland Shark Somniosus microcephalus

open access: yesAging Cell, Volume 25, Issue 5, May 2026.
Greenland shark Somniosus microcephalus shows severe cardiac aging such as fibrosis, lipofuscin buildup, mitochondrial damage, and oxidative stress, unseen in comparison species Etmopterus spinax and Nothobranchius furzeri, yet remain healthy. S. microcephalus resilience suggests unique mechanisms that preserve heart function for centuries, offering ...

Hawksbill turtles in Korean waters: Occurrence records, tracking, and conservation considerations

open access: yesConservation Science and Practice, Volume 8, Issue 5, May 2026.
In Korean waters, diverse efforts, including rescue, rehabilitation, and post‐release satellite tracking, has been conducted to conserve and restore hawksbill turtles. Hawksbill turtles showed three movement patterns and a potential migratory corridor linking Jeju Island to Hainan Island, southern China.

Modeling habitat and bycatch risk for dugongs in Sabah, Malaysia

open access: yesEndangered Species Research, 2014
Bycatch of marine megafauna in fishing gear is a problem with global implications. Bycatch rates can be difficult to quantify, especially in countries where there are limited data on the abundance and distribution of coastal marine mammals, the ...

Predicting Historical Populations and Evaluating Shifting Baselines of Traditionally Exploited Fisheries

open access: yesFish and Fisheries, Volume 27, Issue 3, Page 506-518, May 2026.
ABSTRACT Development of data‐intensive stock assessment and ecosystem‐based models has improved our understanding of shifting species abundance in response to fishing, ocean ecology, and species interactions. Along with this analytical progress is evidence that many stocks lack data required for complex models, resulting in data‐limited options for ...
