The Role of Vegetated Coastal Wetlands for Marine Megafauna Conservation [PDF]
Trends in Ecology & Evolution, 2019 Habitat loss is accelerating a global extinction crisis. Conservation requires understanding links between species and habitats. Emerging research is revealing important associations between vegetated coastal wetlands and marine megafauna, such as cetaceans, sea turtles, and sharks.

Embracing Complexity and Complexity-Awareness in Marine Megafauna Conservation and Research
Frontiers in Marine Science, 2018 Conservation of marine megafauna is nested within an intricate tapestry of multiple ocean resource uses which are, in turn, embedded in a dynamic and complex ecological ocean system that varies and shifts across a wide range of spatial and temporal ...

Laser photogrammetry improves size and demographic estimates for whale sharks [PDF]
PeerJ, 2015 Whale sharks Rhincodon typus are globally threatened, but a lack of biological and demographic information hampers an accurate assessment of their vulnerability to further decline or capacity to recover.

Insight into the kinematics of blue whale surface foraging through drone observations and prey data [PDF]
PeerJ, 2020 To understand how predators optimize foraging strategies, extensive knowledge of predator behavior and prey distribution is needed. Blue whales employ an energetically demanding lunge feeding method that requires the whales to selectively feed where ...

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 ...

Understanding individual and population-level effects of plastic pollution on marine megafauna
Endangered Species Research, 2020 Plastic pollution is increasing rapidly throughout the world’s oceans and is considered a major threat to marine wildlife and ecosystems. Although known to cause lethal or sub-lethal effects to vulnerable marine megafauna, population-level impacts of ...

Using Drone Footage to Analyze the Effect of Diver Presence on Juvenile Manta Ray Behavior
DronesManta ray tourism has become a multi-million-dollar industry proposed as a conservation tool in recent decades; however, its impacts remain unclear. We use drones and Markov models to quantify the effects of diver presence on a juvenile population of the

From sea monsters to charismatic megafauna: Changes in perception and use of large marine animals.
PLoS ONE, 2019 Marine megafauna has always elicited contrasting feelings. In the past, large marine animals were often depicted as fantastic mythological creatures and dangerous monsters, while also arousing human curiosity.
