Multi‐Platform Deployments of Low‐Cost Devices for Cetacean Passive Acoustic Monitoring
Remote Sensing in Ecology and Conservation, EarlyView.Recent advances in affordable, user‐friendly devices offer new opportunities to overcome cost constraints of underwater passive acoustic monitoring (PAM) and expand acoustic data collection. In this study, we deployed low‐cost acoustic recorders and underwater cameras across a range of platforms in the Western Mediterranean, including fishing gear ...

Anais da Academia Brasileira de Ciências, 2014 The South American Pleistocene mammal fauna includes great-sized animals that have intrigued scientists for over two centuries. Here we intend to update the knowledge on its palaeoecology and provide new evidence regarding two approaches: energetics and ...

Conservation Science and Practice, 2020 Conservation in eastern and southern Africa has historically centered on megafauna and protected areas (PAs), yet, in the face of rapid change, biodiversity outside of PAs is under threat.

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Physical trampling is a ubiquitous activity of walking vertebrates, but is poorly understood as a mechanism impacting biogeochemical cycling in soil. Lack of detailed knowledge of soil abiotic–biotic interactions underlying trampling effects, and the primary sources of ...

Wild large herbivores promote plant diversity and functional redundancy by reducing dominance
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Large herbivores can strongly shape plant communities, yet studies report contrasting effects on species richness, and how they affect plant functional diversity remains largely unknown.

Long-term collapse in fruit availability threatens Central African forest megafauna [PDF]
, 2020 Afrotropical forests host many of the world’s remaining megafauna, but even here they are confined to areas where direct human influences are low. We use a rare long-term dataset of tree reproduction and a photographic database of forest elephants to ...

The development of agriculture in the Americas: an ecological perspective
Ecosphere, 2010 Agriculture began independently in both North and South America ∼10,000 years before present (YBP), within a few thousand years of the arrival of humans in the Americas. This contrasts with the thousands of years that people were present in the old world

Nature Communications, 2023 The worldwide extinction of megafauna during the Late Pleistocene and Early Holocene is evident from the fossil record, with dominant theories suggesting a climate, human or combined impact cause.

Megafauna moves nutrients uphill [PDF]
Current Biology, 2016 Large animals have a disproportionate capacity to transport nutrients along gradients and against water flow directions, making them more available to ecosystems and ultimately saving them from disappearing in sea floor sediments. Megafauna extinctions have reduced this capacity dramatically, while humans and their livestock aren’t stepping in to ...
