Mismatches in scale between highly mobile marine megafauna and marine protected areas

Frontiers in Marine Science, 2022
Marine protected areas (MPAs), particularly large MPAs, are increasing in number and size around the globe in part to facilitate the conservation of marine megafauna under the assumption that large-scale MPAs better align with vagile life histories ...

Drone-Based Assessment of Marine Megafauna off Wave-Exposed Sandy Beaches

Remote Sensing, 2023
The wave-impacted waters off exposed sandy beaches support marine megafauna, including dolphins, whales, sharks, rays and turtles. To characterise variation in megafaunal assemblages in this challenging habitat, we used drone-based remote sensing to ...

Marine megafauna catch in Thai small‐scale fisheries

Aquatic Conservation: Marine and Freshwater Ecosystems, 2023
Small‐scale fisheries are a global conservation threat to marine megafauna (marine mammals, sea turtles, and elasmobranchs). There is currently limited information about marine megafauna catch in Thailand's small‐scale fisheries, which is required for ...

Toward Data-Driven Glare Classification and Prediction for Marine Megafauna Survey [PDF]

ICPR Workshops, 2023
Critically endangered species in Canadian North Atlantic waters are systematically surveyed to estimate species populations which influence governing policies. Due to its impact on policy, population accuracy is important.

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

An overview of forensic ecology applied for marine megafauna conservation

Forensic Science International: Animals and Environments
Ocean currents, driven by gravity, wind, and water density, disperse marine biota worldwide, often leading species to shorelines alive or as carcasses.

Ocean lens for biodiversity within One Health: Claims to coastal-marine megafauna species, Brazil

CABI One Health
Coastal-marine megafauna (marine mammals, reptiles, and seabirds) are key components of healthy marine-coastal environments. These ecosystems are tied to the land and the ocean through rivers, estuaries, beaches, mangroves, and restinga systems.

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.

Ecological impacts of climate change on Arctic marine megafauna.

Trends in Ecology & Evolution, 2023
Global warming affects the Arctic more than any other region. Mass media constantly relay apocalyptic visions of climate change threatening Arctic wildlife, especially emblematic megafauna such as polar bears, whales, and seabirds. Yet, we are just beginning to understand such ecological impacts on marine megafauna at the scale of the Arctic.

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 ...
