Long-term change in the abyssal NE Atlantic: The ‘Amperima Event’ revisited [PDF]
, 2010 The results from a time series study (1989–2005) at a depth of 4850 m on the Porcupine Abyssal Plain, NE Atlantic, are presented, showing radical changes in the density of large invertebrates (megafauna) over time.

Climate-human interaction associated with southeast Australian megafauna extinction patterns
Nature Communications, 2019 Whether Australia’s Pleistocene megafauna extinctions were caused by climate change, humans, or both is debated. Here, the authors infer the spatio-temporal trajectories of regional extinctions and find that water availability mediates the relationship ...

Different megafauna vary in their seed dispersal effectiveness of the megafaunal fruit Platymitra macrocarpa (Annonaceae). [PDF]
PLoS ONE, 2018 The world's largest terrestrial animals (megafauna) can play profound roles in seed dispersal. Yet, the term 'megafauna' is often used to encompass a diverse range of body sizes and physiologies of, primarily, herbivorous animals. To determine the extent

Freshwater megafauna shape ecosystems and facilitate restoration [PDF]
Freshwater megafauna, such as sturgeons, giant catfishes, river dolphins, hippopotami, crocodylians, large turtles, and giant salamanders, have experienced severe population declines and range contractions worldwide.

Scientific ReportsKelp forest trophic cascades have been extensively researched, yet indirect effects to the zooplankton prey base and gray whales have not been explored. We investigate the correlative patterns of a trophic cascade between bull kelp and purple sea urchins

PLANTS, PEOPLE, PLANET, EarlyView.Asian elephants play crucial roles in ecosystem functioning, and their interactions with plants influence above‐ and belowground carbon cycling. We tested whether their mechanically destructive foraging triggers short‐term, stress‐induced shifts in tree root exudation, an underappreciated pathway linking herbivory to belowground carbon processes.

PLANTS, PEOPLE, PLANET, EarlyView.Many plant species worldwide are struggling to regenerate due to the ongoing effects of climate change. These effects appear to be further exacerbated by the loss of keystone megafauna, which were important seed dispersers. By identifying the traits commonly seen in seeds spread by modern elephants, it is possible to predict which species likely ...

Review and suggestions for upgrading StrandNet as a key element of the Reef 2050 Integrated Monitoring and Reporting Program: final report of the StrandNet team in the megafauna expert group [PDF]
, 2020 The objective of this report is to provide an overview of the present StrandNet program and suggest how it might be improved to enable the StrandNet database to function as a central component of the megafauna component of the Reef 2050 Integrated ...

Environmental drivers of megafauna and hominin extinction in Southeast Asia
, 2020 Southeast Asia has emerged as an important region for understanding hominin and mammalian migrations and extinctions. High-profile discoveries have shown that Southeast Asia has been home to at least five members of the genus Homo.

Scientific Reports, 2022 People could have hunted Madagascar’s megafauna to extinction, particularly when introduced taxa and drought exacerbated the effects of predation. However, such explanations are difficult to test due to the scarcity of individual sites with unambiguous ...
