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’?

Megafauna

, 2019
The megafauna, or megabenthos, represents the largest body size class of organisms associated with the seafloor. It encompasses microbial mats, “giant” unicellular eukaryotes, the largest demersal fish, and a very broad range of metazoan invertebrate ...

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

Proc Natl Acad Sci U S A
International audienceOcean 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,

Assessing the effects of coral reef habitat and marine protected areas on threatened megafauna using aerial surveys

, 2023
Overfishing and habitat degradation are major threats to marine megafauna worldwide. Marine protected areas (MPAs) are effective spatial conservation tools for reducing anthropogenic pressures on threatened species but their benefits for megafauna are ...

Ecological and evolutionary legacy of megafauna extinctions [PDF]

, 2017
For hundreds of millions of years, large vertebrates (megafauna) have inhabited most of the ecosystems on our planet. During the late Quaternary, notably during the Late Pleistocene and the early Holocene, Earth experienced a rapid extinction of large ...

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.

Extinction of eastern Sahul megafauna coincides with sustained environmental deterioration

, 2020
Explanations for the Upper Pleistocene extinction of megafauna from Sahul (Australia and New Guinea) remain unresolved. Extinction hypotheses have advanced climate or human-driven scenarios, in spite of over three quarters of Sahul lacking reliable ...

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.
