Rethinking megafauna [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2020
Concern for megafauna is increasing among scientists and non-scientists. Many studies have emphasized that megafauna play prominent ecological roles and provide important ecosystem services to humanity. But, what precisely are ‘megafauna’?

Investigating the benthic megafauna in the eastern Clarion Clipperton Fracture Zone (north-east Pacific) based on distribution models predicted with random forest

Scientific Reports, 2022
The eastern Clarion Clipperton Fracture Zone (CCZ) is a heterogeneous abyssal environment harbouring relatively low abundances of highly diverse megafauna communities.

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.

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 ...

Megafauna Seed Dispersal in the Neotropics: A Meta-Analysis Shows No Genetic Signal of Loss of Long-Distance Seed Dispersal

Frontiers in Genetics, 2019
Restricted gene flow may lead to the loss of genetic diversity and higher genetic differentiation among populations, but the genetic consequences of megafauna extinction for plant populations still remain to be assessed.

Shaken, not stirred: blue whales show no acoustic response to earthquake events

Royal Society Open Science, 2022
Quantifying how animals respond to disturbance events bears relevance for understanding consequences to population health. We investigate whether blue whales respond acoustically to naturally occurring episodic noise by examining calling before and after

Paleoamerican exploitation of extinct megafauna revealed through immunological blood residue and microwear analysis, North and South Carolina, USA

Scientific Reports, 2023
Previous immunological studies in the eastern USA have failed to establish a direct connection between Paleoamericans and extinct megafauna species.

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 ...

Lake levels and trackways: An alternative model to explain the timing of human-megafauna trackway intersections, Tularosa Basin, New Mexico

Quaternary Science Advances, 2021
The margins of Paleolake Otero in southern New Mexico, USA, contain one of the largest concentrations of fossilized late Pleistocene (Rancholabrean) megafauna trackways in North America.
