Similar circling movements observed across marine megafauna taxa. [PDF]

iScience, 2021
Advances in biologging technology have enabled 3D dead-reckoning reconstruction of marine animal movements at spatiotemporal scales of meters and seconds. Examining high-resolution 3D movements of sharks (Galeocerdo cuvier, N = 4; Rhincodon typus, N = 1), sea turtles (Chelonia mydas, N = 3), penguins (Aptenodytes patagonicus, N = 6), and marine mammals

Editorial: Tracking marine megafauna for conservation and marine spatial planning [PDF]

Frontiers in Marine Science, 2023
Antarctic terrestrial biodiversity faces multiple threats, from invasive species to climatechange. Yet no large-scale assessments of threat management strategies exist. Applying astructured participatory approach, we demonstrate that existing conservation efforts areinsufficient in a changing world, estimating that 65% (at best 37%, at worst 97%) of ...

Energyscapes pinpoint marine megafauna feeding hotspots in the Mediterranean. [PDF]

Proc Natl Acad Sci U S A
Ocean giants shape the structure and functioning of marine food webs via trophic top–down controls, landscapes of fear, vertical and horizontal redistribution of nutrients, energy, and matter. Yet, they face threats from overfishing, pollution, habitat degradation, and climate change, and one-third of marine megafauna species are at risk of extinction,

The Status of Marine Megafauna Research in Macaronesia: A Systematic Review

Frontiers in Marine Science, 2022
Marine megafauna serve valuable ecological and economical roles globally, yet, many species have experienced precipitous population declines. The significance of marine megafauna is particularly evident in Macaronesia, a complex of oceanic archipelagos ...

Using Drones to Assess Volitional Swimming Kinematics of Manta Ray Behaviors in the Wild

Drones, 2022
Drones have become increasingly popular tools to study marine megafauna but are underutilized in batoid research. We used drones to collect video data of manta ray (Mobula cf.

Key Questions in Marine Megafauna Movement Ecology [PDF]

Trends in Ecology & Evolution, 2016
It is a golden age for animal movement studies and so an opportune time to assess priorities for future work. We assembled 40 experts to identify key questions in this field, focussing on marine megafauna, which include a broad range of birds, mammals, reptiles, and fish.

Quantitative overview of marine debris ingested by marine megafauna

Marine Pollution Bulletin, 2020
This review quantifies plastic interaction in marine biota. Firstly, entanglement and ingestion records for all marine birds, mammals, turtles, fish, and invertebrate species, are summarized from 747 studies. Marine debris affected 914 species through entanglement and/or ingestion. Ingestion was recorded for 701 species, entanglement was documented for

The Azores: A Mid-Atlantic Hotspot for Marine Megafauna Research and Conservation

Frontiers in Marine Science, 2020
The increasing public perception that marine megafauna is under threat is an outstanding incentive to investigate their essential habitats (EMH), their responses to human and climate change pressures, and to better understand their largely unexplained ...

Residency, movement patterns, behavior and demographics of reef manta rays in Komodo National Park [PDF]

PeerJ, 2022
Background The reef manta ray (Mobula alfredi) is a globally threatened species and an iconic tourist attraction for visitors to Indonesia’s Komodo National Park (NP). In 2013, manta ray fishing was banned in Komodo NP and its surroundings, preceding the
